The present invention relates to a communication system and a method thereof, and more particularly, to a communication system and a method for distributing image processing to a plurality of servers on a network to perform separated or isolated image processing desired by a user, wherein the communication system and the method make it possible to improve the speed of image processing on a network platform at reduced costs.
In general, techniques for synthesizing images desired by a user on a network are widely known.
Synthesized image is usually generated by overlapping and joining a number of pre-existing images such as images having already been stored in a server connected through a network or images having been made available from digital still cameras. In some cases, the synthesized image may be generated by a texture mapping.
However, there are problems in that synthesized images generated by using the above conventional methods give rise to the occurrences of motion blur. For example, motion blur commonly occurs with a moving body that cannot be accurately adjusted into the synthesized images. Consequently, synthesizing processes are performed with low accuracy and unnatural appearances are frequently generated in the synthesized images.
Additionally, if one server performs synthesizing process in a multiple bundle task, a significant duration of time is required for the process. For example, even when the same background images are to be overlapped, the overlapping process is repeated as many times as the number of images desired. This poses a problem to users in that when the processing services are charged by time, the cost can be a considerable burden.
In view of the foregoing, it is an object of the present invention to provide a communication system and a method for distributing image processing characterized by having multiple tasks to a plurality of servers on a network to perform separated or isolated image processing desired by a user, wherein the communication system and the method make it possible to improve the speed of image processing on a network platform at reduced costs.

Further, in this specification, encoding means to convert the image data into data of the foreground component image, the background component image, the motion vector, the positional information, the amount of motion blur and the mixture ratio information, and the data thereof is referred to as encoded data.
Further, it does not matter whether each function of the separation server 11 is implemented by hardware or software. That is, each block diagram of the present invention may be considered as a block diagram of hardware or as a functional block diagram of software.
The input image supplied to the separation server 11 is supplied town object extracting unit 101, an area specifying unit 103, a mixture ratio calculator 104 and a foreground/background separator 105.
The object extracting unit 101 roughly extracts an image object corresponding to the foreground object of the input image and supplies the extracted image object to the motion detector 102. The object extracting unit 101 detects, for example, the outline of the image object corresponding to the foreground object of the input image and roughly extracts the image object corresponding to the foreground object.
The object extracting unit 101 roughly extracts an image object corresponding to the background object of the input image and supplies the extracted image object to the motion detector 102. The object extracting unit 101 roughly extracts the image object corresponding to the background object on the basis of, for example, the difference between the input image and the image object corresponding to the extracted foreground object.
Further, for example, the object extracting unit 101 may roughly extract the image object corresponding to the foreground object and the image object corresponding to the background object on the basis of the difference between the background image stored in an internally provided background memory and the input image.
The motion detector 102 calculates a motion vector for a roughly extracted image object corresponding to the foreground object by using techniques such as a block matching method, an equally-dividing method, a phase correlating method or a pixel recursive method to supply the calculated motion vector and the positional information of the motion vector (information specifying positions of pixels corresponding to the motion vector) to the area specifying unit 103 and the motion blur adjusting unit 106. The motion vector output from the motion detector 102 includes information corresponding to the amount of movement v.
Further, for example, the motion detector 102 may output the motion vector of each image object to the motion blur adjusting unit 106 along with the pixel positional information specifying pixels of image object.
The amount of movement v which indicates the positional variation of the image corresponding to the moving object is expressed in units of pixel interval. For example, when the object image corresponding to the foreground is moved and displayed at a position that is separated by 4 pixels in a frame following a reference frame, the amount of movement v of the object image corresponding to the foreground is 4.
Further, the object extracting unit 101 and the motion detector 102 are required for adjusting the amount of motion blur corresponding to the moving object.
The area specifying unit 103 specifies the foreground area, the background area or the mixed area for each pixel of the input image and supplies information indicating the foreground area, the background area or the mixed area for each pixel, to the mixture ratio calculator 104, the foreground/background separator 105 and the motion blur adjusting unit 106.
The mixture ratio calculator 104 calculates a mixture ratio corresponding to pixels in the mixed area on the basis of the input image and the area information supplied from the area specifying unit 103 and supplies the calculated mixture ratio to the foreground/background separator 105.
The mixture ratio α is a value indicating a ratio of image component (hereinafter, referred to as background component) corresponding to the background object in pixel values as shown in equation (3) to be described later.
The foreground/background separator 105 separates the input image into a foreground component image having only the image component (hereinafter, referred to as foreground component) corresponding to the foreground object and a background component image having only the background component on the basis of the area information supplied from the area specifying unit 103 and the mixture ratio α supplied from the mixture ratio calculator 104 to supply the foreground component image to the motion blur adjusting unit 106 and the selector 107. Further, it may be considered that the separated foreground component image is the final output. Compared to the conventional methods where only the foreground and background are specified and separated without considering the mixed area, more accurate foreground and background can be obtained.
The motion blur adjusting unit 106 determines a unit of processing which specifies one or more pixels in the foreground component image, based on the amount of movement v known from the motion vector and the area information. The unit of processing is a data specifying a group of pixels that is a target of motion blur adjusting process.
The motion blur adjusting unit 106 adjusts the amount of motion blur in the foreground component image by removing the motion blur in the foreground component image, decreasing the amount of motion blur, increasing the amount of motion blur, etc. based on the amount of motion blur input to the separation server 11, the foreground component image supplied from the foreground/background separator 105, the motion vector and the positional information thereof supplied from the motion detector 102 and the unit of processing, and outputs the foreground component image of which the amount of motion blur is adjusted to the selector 107. The motion vector and the positional information thereof may not be used.
Here, the motion blur means distortion included in an image corresponding to a moving object, generated by the motion of object in real society which is a target of picking up an image and by picking up characteristics of sensors.
The selector 107 selects the foreground component image supplied from the foreground/background separator 105 or the foreground component image supplied from the motion blur adjusting unit 106 of which the amount of motion blur is adjusted, based on, for example, a selection signal corresponding to a selection made by a user and then, outputs the selected foreground component image.
Next, with reference to
The sensor 76a picks up the image of the object 112 corresponding to the foreground along with the object corresponding to the background. The sensor 76a outputs the picked up in a frame unit. For example, the sensor 76a outputs an image having 30 frames per second. The exposure time of the sensor 76a may be set to 1/30 second. The exposure time means a time interval which starts at the point of converting the input light into charges and ends at the point when the input light has converted into charges. Hereinafter, the exposure time is referred to as a shutter time.
As shown in
The charge stored in the detection element is converted into a voltage value by means of a circuit not shown and the voltage value is converted into a pixel value such as digital data, etc. to be output. Therefore, each pixel value output from the sensor 76a has a value projected to one-dimensional space as a result of integrating some portion having spatial extension of an object corresponding to foreground or background with respect to the shutter time.
The separation server 11 extracts any significant information, for example, mixture ratio α, hidden in the output signal by means of storing operation of such sensor 76a. The separation server 11 adjusts the amount of distortion, for example, the amount of motion blur resulting from the mixture of the same image object of the foreground. Further, the separation server 11 adjusts the amount of distortion resulting from the mixture of image object of the foreground and image object of the background.
The pixel values of pixels in the background area comprise only the components of the background, that is, the components of the image corresponding to the background object. The pixel values of pixels in the foreground area comprise only the components of the foreground, that is, the components of the image corresponding to the foreground object.
The pixel values of pixels in the mixed area comprise the components of the background and the components of the foreground. Since the pixel values of pixels in the mixed area comprise the components of the background and the components of the foreground, the mixed area can be mentioned as a distortion area. Further, the mixed area is classified into a covered background area and an uncovered background area.
The covered background area is a mixed area corresponding to a front end portion in a direction in which the foreground object moves in respect to the foreground area and is an area in which the background components is hidden behind the foreground with time elapsing.
In contrast, the uncovered background area is a mixed area corresponding to the rear end portion in a direction in which the foreground object moves in respect to the foreground area and is an area in which the background components appear with time elapsing.
As such, the image including the foreground area, the background area, the covered background area or the uncovered background area is input to the area specifying unit 103, the mixture ratio calculator 104 and the foreground/background separator 105 as the input image.
Pixel values of F01 to F04 shown in
The vertical direction in
Now, a case of when the shutter time equals to the frame interval will be explained as an example.
The horizontal direction in
When the object of foreground and the object of background are stationary, light to be input to the sensor 76a is not varied for a time interval corresponding to a shutter time.
Here, the time interval corresponding to the shutter time is divided into two or more equivalent lengths. For example, if a virtual division number is 4, the model diagram shown in
The uppermost row in the drawing corresponds to a first divided time interval after the shutter is opened. The second row from the uppermost in the drawing corresponds to a second divided time interval after the shutter is opened. The third row from the uppermost in the drawing corresponds to a third divided time interval after the shutter is opened. The fourth row from the uppermost in the drawing corresponds to a fourth divided time interval after the shutter is opened.
Now, the time interval by which the shutter time is divided according to the amount of movement v is referred to as shutter time/v.
When the object corresponding to the foreground is stationary, since light input to the sensor 76a is not varied, the foreground component F01/v has the same value the pixel value F01 divided by the virtual division number. Similarly, when the object corresponding to the foreground is stationary, the foreground component F02/v has the same value as the pixel value F02 divided by the virtual division number, the foreground component F03/v has the same value as the pixel value F03 divided by the virtual division number and the foreground component F04/v has the same value as the pixel value F04 divided by the virtual division number.
When the object corresponding to the background is stationary, since light input to the sensor 76a is not varied, the background component B01/v has the same value as the pixel value B01 divided by the virtual division number. Similarly, when the object corresponding to the background is stationary, the background component B02/v has the same value as the pixel value B02 divided by the virtual division number, the background component B03/v has the same value as the pixel value B03 divided by the virtual division number and the background component B04/v has the same value as the pixel value B04 divided by the virtual division number.
That is, when an object corresponding to the foreground is stationary, since light input to the sensor 76a is not varied for the time interval corresponding to the shutter time, the foreground component F01/v corresponding to a first shutter time/v after the shutter is opened, the foreground component F01/v corresponding to a second shutter time/v after the shutter is opened, the foreground component F01/v corresponding to a third shutter time/v after the shutter is opened and the foreground component F01/v corresponding to a fourth shutter time/v after the shutter is opened all have the same value. F02/v to F04/v have also the same relation as F01/v.
When an object corresponding to the background is stationary, since light input to the sensor 76a is not varied for the time interval corresponding to the shutter time, the background component B01/v corresponding to a first shutter time/v after the shutter is opened, the background component B01/v corresponding to a second shutter time/v after the shutter is opened, the background component B01/v corresponding to a third shutter time/v after the shutter is opened and the background component B01/v corresponding to a fourth shutter time/v after the shutter is opened all have the same value. B02/v to B04/v have the same value as B01/v.
Next, a case of when an object corresponding to the foreground is moving and the object corresponding to the background is stationary will be explained.
In
Since the object corresponding to the foreground is moving to cover the object corresponding to the background with time elapsing, the components included in the pixel values of pixels belonging to the covered background area is changed from the background components to the foreground components at certain time point of the time interval corresponding to the shutter time.
For example, the pixel values M of which edge is a bold line in
M=B02/v+B02/v+F07/v+F06/v (1)
For example, since the fifth pixel from the leftmost includes the background component corresponding to a first shutter time/v and the foreground component corresponding to a third shutter time/v, the mixture ratio α of the fifth pixel from the leftmost is ¼. Since the sixth pixel from the leftmost includes the background component corresponding to a second shutter time/v and the foreground component corresponding to the second shutter time/v, the mixture ratio α of the sixth pixel from the leftmost is ½. Since the seventh pixel from the leftmost includes the background component corresponding to the third shutter time/v and the foreground component corresponding to the first shutter time/v, the mixture ratio α of the seventh pixel from the leftmost is ¾.
Since it can be supposed that the object corresponding to the foreground is a rigid body and the foreground image is moving at an uniform speed to be displayed at a position displaced to the right by 4 pixels in a next frame, for example, the foreground component F07/v, of the fourth pixel from the leftmost in
Since it can be supposed that the object corresponding to the foreground is a rigid body and the foreground image is moving at an uniform speed to be displayed at a position displaced to the right by 4 pixels in a next frame, for example, the foreground component F06/v of the third pixel from the leftmost in
Since it can be supposed that the object corresponding to the foreground is a rigid body and the foreground image is moving at an uniform speed to be displayed at a position displaced to the right by 4 pixels in a next frame, for example, the foreground component F05/v of the second pixel from the leftmost in
Since it can be supposed that the object corresponding to the foreground is a rigid body and the foreground image is moving at an uniform speed to be displayed at a position displaced to the right by 4 pixels in a next frame, for example, the foreground component F04/v of the leftmost pixel in
The foreground area corresponding to a moving object may be mentioned as a distortion area because it includes the motion blur as described by the above.
In
Since the object corresponding to the foreground covering the object corresponding to the background is moving to be displaced from the object corresponding to the background with time elapsing, the components included in the pixel values of pixels belonging to the uncovered background area is changed from the foreground components to the background components at certain time point of the time interval corresponding to the shutter time.
For example, the pixel values M′ of which edge is a bold line in
M′=F02/v+F01/v+B26/v+B26/v (2)
For example, since the fifth pixel from the leftmost includes the background component corresponding to a third shutter time/v and the foreground component corresponding to a first shutter time/v, the mixture ratio α of the fifth pixel from the leftmost is ¾. Since the sixth pixel from the leftmost includes the background component corresponding to a second shutter time/v and the foreground component corresponding to the second shutter time/v, the mixture ratio α of the sixth pixel from the leftmost is ½. Since the seventh pixel from the leftmost includes the background component corresponding to the first shutter time/v and the foreground component corresponding to the third shutter time/v, the mixture ratio α of the seventh pixel from the leftmost is ¼.
More generalizing combining equation (1) and equation (2), the pixel value M can also be expressed by equation (3).
Here, α is a mixture ratio. B is a pixel value of the background and Fi/v is a foreground component.
Since it can be supposed that the object corresponding to the foreground is a rigid body and is moving at an uniform speed and the amount of movement v is 4, for example, the foreground component F01/v of the fifth pixel from the leftmost in
Since it can be supposed that the object corresponding to the foreground is a rigid body and is moving at an uniform speed and the virtual division number is 4, for example, the foreground component F02/v of the sixth pixel from the leftmost in
Since it can be supposed that the object corresponding to the foreground is a rigid body and is moving at an uniform speed and the amount of movement v is 4, for example, the foreground component F03/v of the seventh pixel from the leftmost in
In the explanations of
A frame #n+1 is a frame next to a frame #n and a frame #n+2 is a frame next to the frame #n+1.
A model in which the pixels of the foreground area, the background area and the mixed area extracted from one of the frame #n to the frame #n+2 and the pixel values of the extracted pixels are expanded in the time direction with the amount of movement v being 4 is shown in
Since the object A corresponding to the foreground is moving, the pixel values of the foreground area comprise 4 different foreground components according to intervals of a shutter time/v. For example, the leftmost pixel in the foreground area shown in
Since an object corresponding to the background is stationary, the light corresponding to the background input to the sensor 76a for the time interval corresponding to the shutter time does not change. In this case, the pixel values of the background area do not include the motion blur.
The pixel values of pixels belonging to the mixed area containing the covered background area or the uncovered background area is comprised the foreground components and the background components.
Next, a model will be explained that when an image corresponding to an object is moving, the pixel values of pixels are adjacent in one row in a plurality of frames and are at the same positions in the frames are expanded in the time direction. For example, when the image corresponding to the object is moving horizontally with respect to the screen, the pixels being in one line on the screen can be selected as pixels being adjacent in one row.

Returning to
The mixture ratio calculator 104 calculates the mixture ratios α for each pixel included in the mixed area on the basis of the pixel values from a plurality of frames and the area information, and supplies the calculated mixture ratio α to the foreground/background separator 105.
The foreground/background separator 105 extracts the foreground component image having only the foreground components on the basis of the pixel values from a plurality of frames, the area information and the mixture ratio α and supplies it to the motion blur adjusting unit 106.
The motion blur adjusting unit 106 adjusts the amount of motion blur included in the foreground component image on the basis of the foreground component image supplied from the foreground/background separator 105, the motion vector supplied from the motion detector 102 and the area information supplied from the area specifying unit 103 and then outputs the foreground component image in which the motion blur is adjusted.
Referring to the flowchart of
Further, in step S11, the area specifying unit 103 may generate the area information indicating to which of the foreground area, the background area and the mixed area (the covered background area and the uncovered background area are not distinguished) that each pixel of the input image belongs on the basis of the input image. In this case, the foreground/background separator 105 and the motion blur adjusting unit 106 determine whether the mixed area is the covered background area or the uncovered background area on the basis of the direction of the motion vector. For example, when the order of the foreground area, the background area and the mixed area are sequentially arranged for the direction of the motion vector, it is determined that the mixed area is the covered background area. when the order of the background area, the mixed area and the foreground area are sequentially arranged in the direction of the motion vector, it is determined that the mixed area is the uncovered background area.
In step S12, the mixture ratio calculator 104 calculates the mixture ratio α for each pixel included in the mixed area on the basis of the input image and the area information. Details of the mixture ratio calculating processing will be given later. The mixture ratio calculator 104 supplies the calculated mixture ratio α to the foreground/background separator 105.
In step S13, the foreground/background separator 105 extracts the foreground components from the input image on the basis of the area information and the mixture ratio α to supply them to the motion blur adjusting unit 106 as the foreground component image.
In step S14, the motion blur adjusting unit 106 generates units of processing which specify the positions of the image in pixels which are continuously arranged in the moving direction and which correspond to any of the uncovered background area, the foreground area and the covered background area on the basis of the motion vector and the area information, and adjusts the amount of motion blur included in the foreground components corresponding to the units of processing. The processing details of adjusting the amount of motion blur will be explained later.
In step S15, the separation server 11 determines whether the processing is finished for the whole screen or not, and if it is determined that the processing is not finished for the whole screen, the procedure returns to step S14, and the process of adjusting the amount of motion blur for the foreground components corresponding to the unit of processing is repeated.
In step S15, if it is determined that the processing is finished for the whole screen, the process ends.
Like this, separation server 11 can separate the foreground and the background to adjust the amount of motion blur included the foreground. That is, the separation server 11 can adjust the amount of motion blur included in the sample data that are the pixel values of pixels of the foreground.
Now, the respective configurations of the area specifying unit 103, the mixture ratio calculator 104, the foreground/background separator 105 and the motion blur adjusting unit 106 will be explained.

Next, referring to
When the object corresponding to the foreground is moving, the position on the screen of the image corresponding to the object varies every frame. As shown in
In
The foreground components corresponding to the object included in the second to the thirteenth pixels from the leftmost in the frame #n are included in the sixth to the seventeenth pixels from the leftmost in the frame #n+1.
In the frame #n, pixels belonging to the covered background area are the eleventh to thirteenth pixels from the leftmost and pixels belonging to the uncovered background area are the second to fourth pixels from the leftmost. In the frame #n+1, pixels belonging to the covered background area are the fifteenth to seventeenth pixels from the leftmost and pixels belonging to the uncovered background area are the sixth to eighth pixels from the leftmost.
In the example shown in
Next, variation of the pixel values of pixels belonging to the mixed area in front or back of the indicated frame will be explained.
In the frame #n that is shown in
Here, since the object corresponding to the background is stationary, the pixel value of the fifteenth pixel from the leftmost in the frame #n−1 is not changed from the pixel value of the fifteenth pixel from the leftmost in the frame #n−2. Similarly, the pixel value of the sixteenth pixel from the leftmost in the frame #n−1 is not changed from the pixel value of the sixteenth pixel from the leftmost in the frame #n−2 and the pixel value of the seventeenth pixel from the leftmost in the frame #n−1 is not changed from the pixel value of the seventeenth pixel from the leftmost in the frame #n−2.
That is, since pixels in the frame #n−1 and the frame #n−2 corresponding to the pixels belonging to the covered background area in the frame #n comprised only the background components and the pixel values thereof are not changed, the absolute value of the difference thereof is almost 0. Therefore, the stationary/moving determination on the pixels in the frame #n−1 and the frame #n−2 corresponding to pixels belonging to the mixed area in the frame #n is determined to be stationary by the stationary/moving determining portion 202-4.
Since pixels belonging to the covered background area in the frame #n include the foreground components, the pixel values thereof are different from those in the case of including only the background components in the frame #n−1. Therefore, the stationary/moving determination on the pixels belonging to the mixed area in the frame #n and pixels in the corresponding frame #n−1 is determined to be moving by the stationary/moving determining portion 202-3.
Like the above, when the stationary/moving determination result indicating motion status is supplied from the stationary/moving determining portion 202-3 and the stationary/moving determination result indicating stationary status is supplied from the stationary/moving determining portion 202-4, the area determining portion 203-3 determines that the corresponding pixel belongs to the covered background area.
In the frame #n that is shown in
Here, since the object corresponding to the background is stationary, the pixel value of the second pixel from the leftmost in the frame #n+2 is not changed from the pixel value of the second pixel from the leftmost in the frame #n+1. Similarly, the pixel value of the third pixel from the leftmost in the frame #n+2 is not changed from the pixel value of the third pixel from the leftmost in the frame #n+1 and the pixel value of the fourth pixel from the leftmost in the frame #n+2 is not changed from the pixel value of the fourth pixel from the leftmost in the frame #n+1.
That is, since pixels in the frame #n+1 and the frame #n+2 corresponding to the pixels belonging to the uncovered background area in the frame #n comprised only the background components and the pixel values thereof are not changed, the absolute value of the difference thereof is almost 0. Therefore, the stationary/moving determination on the pixels in the frame #n+1 and the frame #n+2 corresponding to pixels belonging to the mixed area in the frame #n is determined to be stationary by the stationary/moving determining portion 202-1.
Since pixels belonging to the uncovered background area in the frame #n include the foreground components, the pixel values thereof are different from those in the case of including only the background components in the frame #n+1. Therefore, the stationary/moving determination on the pixels belonging to the mixed area in the frame #n and pixels in the corresponding frame #n+1 is determined to be moving by the stationary/moving determining portion 202-2.
Like the above, when the stationary/moving determination result indicating motion status is supplied from the stationary/moving determining portion 202-2 and the stationary/moving determination result indicating stationary status is supplied from the stationary/moving determining portion 202-1, the area determining portion 203-1 determines that the corresponding pixel belongs to the uncovered background area.
When it is determined that a pixel in the frame #n−1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n and the pixel in the frame #n, are stationary and when it is determined that the pixel in the frame #n and the pixel in the frame #n+1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n are stationary, the area specifying unit 103 determines that the pixel that is a target of determination in the frame #n belongs to the stationary area.
When it is determined that the pixel in the frame #n−1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n and the pixel in the frame #n, are moving and when it is determined that the pixel in the frame #n and the pixel in the frame #n+1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n are moving, the area specifying unit 103 determines that the pixel that is a target of determination in the frame #n belongs to the moving area.
When it is determined that the pixel in the frame #n and the pixel in the frame #n+1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n, are moving and when it is determined that the pixel in the frame #n+1 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n and the pixel in the frame #n+2 located at the same position as the position in the image of the pixel that is a target of determination in the frame #n are stationary, the area specifying unit 103 determines that the pixel that is a target of determination in the frame #n belongs to the uncovered background area.

Next, referring to the flowchart of
In step S202, the stationary/moving determining portion 202-3 determines whether it is stationary or not for the pixel in the frame #n−1 and the pixel in the frame #n located at the same position and if it is determined to be stationary, the procedure proceeds to step S203. The stationary/moving determining portion 202-2 determines whether it is stationary or not for the pixel in the frame #n and the pixel in the frame #n+1 located at the same position.

The area determining portion 203-2 supplies the stationary area determinating flag to the frame memory storing determinating flag 204 and the procedure proceeds to step S205.
When it is determined to be moving for the pixel in the frame #n−1 and the pixel in the frame #n position located at the same position in step S202 or when it is determined to be moving for the pixel in the frame #n and the pixel in the frame #n+1 position located at the same position in step S203, since the pixel in the frame #n does not belong to the stationary area, the processing in step S204 is skipped and the procedure proceeds to step S205.
In step S205, the stationary/moving determining portion 202-3 determines whether it is moving or not for the pixel in the frame #n−1 and the pixel in the frame #n located at the same position and if it is determined to be moving, the procedure proceeds to step S206. The stationary/moving determining portion 202-2 determines whether it is moving or not for the pixel in the frame #n and the pixel in the frame #n+1 located at the same position.
In step S206, when it is determined to be moving for the pixel in the frame #n and the pixel in the frame #n+1 located at the same position, the procedure proceeds to step S207 and the area determining portion 203-2 sets “1” indicating the pixel belongs to the moving area to the moving area determinating flag corresponding to the pixel of which area is determined. The area determining portion 203-2 supplies the moving area determinating flag to the frame memory storing determinating flag 204 and the procedure proceeds to step S208.
When it is determined to be stationary for the pixel in the frame #n−1 and the pixel in the frame #n position located at the same position in step S205 or when it is determined to be stationary for the pixel in the frame #n and the pixel in the frame #n+1 position located at the same position in step S206, since the pixel in the frame #n does not belong to the moving area, the processing in step S207 is skipped and the procedure proceeds to step S208.
In step S208, the stationary/moving determining portion 202-4 determines whether it is stationary or not for the pixel in the frame #n−2 and the pixel in the frame #n−1 located at the same position and if it is determined to be stationary, the procedure proceeds to step S209. The stationary/moving determining portion 202-3 determines whether it is moving or not for the pixel in the frame #n−1 and the pixel in the frame #n located at the same position.
In step S209, when it is determined to be moving for the pixel in the frame #n−1 and the pixel in the frame #n located at the same position, the procedure proceeds to step S210 and the area determining portion 203-3 sets “1” indicating the pixel belongs to the covered background area to the covered background area determinating flag corresponding to the pixel of which area is determined. The area determining portion 203-3 supplies the covered background area determinating flag to the frame memory storing determinating flag 204 and the procedure proceeds to step S211.
When it is determined to be moving for the pixel in the frame #n−2 and the pixel in the frame #n−1 position located at the same position in step S208 or when it is determined to be stationary for the pixel in the frame #n−1 and the pixel in the frame #n position located at the same position in step S209, since the pixel in the frame #n does not belong to the covered background area, the processing in step S210 is skipped and the procedure proceeds to step S211.
In step S211, the stationary/moving determining portion 202-2 determines whether it is moving or not for the pixel in the frame #n and the pixel in the frame #n+1 located at the same position and if it is determined to be moving, the procedure proceeds to step S212. The stationary/moving determining portion 202-1 determines whether it is stationary or not for the pixel in the frame #n+1 and the pixel in the frame #n+2 located at the same position.
In step S212, when it is determined to be stationary for the pixel in the frame #n+1 and the pixel in the frame #n+2 located at the same position, the procedure proceeds to step S213 and the area determining portion 203-1 sets “1” indicating the pixel belongs to the uncovered background area to the uncovered background area determinating flag corresponding to the pixel of which area is determined. The area determining portion 203-1 supplies the uncovered background area determinating flag to the frame memory storing determinating flag 204 and the procedure proceeds to step S214.
When it is determined to be stationary for the pixel in the frame #n and the pixel in the frame #n+1 position located at the same position in step S211 or when it is determined to be moving for the pixel in the frame #n+1 and the pixel in the frame #n+2 position located at the same position in step S212, since the pixel in the frame #n does not belong to the uncovered background area, the processing in step S213 is skipped and the procedure proceeds to step S214.
In step S214, the area specifying unit 103 determines whether area specification has been performed for all the pixels in the frame #n or not and if it is determined that the area specification has not been performed for all the pixels in the frame #n, the procedure returns to step S202 and the area specifying processing is repeated for other pixels.
In step S214, if it is determined that the area specification has been performed for all the pixels in the frame #n, the procedure proceeds to step S215 and the synthesizer 205 generates the area information indicating the mixed area on the basis of the uncovered background area determinating flag and the covered background area determinating flag stored in the frame memory storing determinating flag 204, generates the area information indicating that each pixel belongs to which of the uncovered background area, the stationary area, the moving area and the covered background area and sets the generated area information in the frame memory storing determinating flag 206. Then, the processing ends.
Like the above, the area specifying unit 103 can generate the area information indicating that the each pixel included in the frame belongs to the moving area, the stationary area, the uncovered background area or the covered background area.
Further, the area specifying unit 103 may generate the area information corresponding to the mixed area by applying logical sum to the area information corresponding to the uncovered background area and covered background area and may generate the area information comprised of flags indicating that the each pixel included in the frame belongs to the moving area, the stationary area or the mixed area.
When the object corresponding to the foreground has texture, the area specifying unit 103 can specify the moving area more accurately.
The area specifying unit 103 can output the area information indicating the moving area as the area information indicating the foreground area and the area information indicating the stationary area as the area information indicating the background area.
Further, although it has been explained that the object corresponding to the background is stationary, even when the image corresponding to the background area includes motion, the area specifying processing described above can be applied. For example, when an image corresponding to the background area is moving constantly, the area specifying unit 103 shifts the whole image corresponding to this movement and processes it similarly to the case that the object corresponding to the background is stationary. Further, when an image corresponding to the background area includes other movements locally, the area specifying unit 103 selects pixels corresponding to the movements and performs the aforementioned processing.
An example of a model in which the pixel values of pixels being adjacent in a row in the moving direction of an image corresponding to the foreground object are expanded in the time direction is shown in
In

In the frame #n−1, the pixels belonging to the covered background area are the eleventh to thirteenth pixels from the leftmost and the pixels belonging to the uncovered background area are the second to fourth pixels from the leftmost. In the frame #n, the pixels belonging to the covered background area are the fifteenth to seventeenth pixels from the leftmost pixels belonging to the uncovered background area are the sixth pixels to eighth pixels. In the frame #n+1, the pixels belonging to the covered background area are the nineteenth to twenty first pixels from the leftmost and the pixels belonging to the uncovered background area are the tenth to twelfth pixels from the leftmost.
In the frame #n−1, the pixels belonging to the background area are the first pixel and the fourteenth to twenty first pixels from the leftmost. In the frame #n, the pixels belonging to the background area are the first to fifth pixels and the eighteenth to twenty first pixels from the leftmost. In frame #n+1, the pixels belonging to the background area are the first to ninth pixels from the leftmost.

The correlation value calculator 321 supplies the correlation value calculated for the respective pixels as described by the above to the threshold vale processor 322. Further, the correlation value calculator 321 may apply equation (7) to, for example, 3×3 blocks in the background image where X4 is centered as shown in
The correlation value calculator 321 supplies the absolute value of the difference calculated by the process described above as the correlation value to the threshold value processor 322.
The threshold value processor 322 compares the pixel value of the correlating image to the threshold value th0, sets 1 to the pixel value of the binary object image when the correlation value is not greater than the threshold value th0, sets 0 to the pixel value of the binary object image when the correlation value is greater than the threshold value th0 and outputs the binary object image to which pixel value 0 or 1 is set. The threshold value processor 322 may previously store the threshold value th0 or may use the externally input threshold value th0.
The area determining portion 342 determines area for each pixel in the frame #n on the basis of the binary object image of the frame #n−1, the frame #n and the frame #n+1 stored in the frame memory 341 to generate and output the area information.
When the indicated pixel of the binary object image in the frame #n is 1, the indicated pixel of the binary object image in the frame #n−1 is 1 and the indicated pixel of the binary object image in the frame #n+1 is 1, the area determining portion 342 determines that the indicated pixel in the frame #n belongs to the foreground area.
When the indicated pixel of the binary object image in the frame #n is 1 and the indicated pixel of the binary object image in the frame #n−1 is 0, the area determining portion 342 determines that the indicated pixel in the frame #n belongs to the covered background area.
When the indicated pixel of the binary object image in the frame #n is 1 and the indicated pixel of the binary object image in the frame #n+1 is 0, the area determining portion 342 determines that the indicated pixel in the frame #n belongs to the uncovered background area.
Since the pixel in the frame #n of the binary object image is 1 and the corresponding pixel in the frame #n+1 is 0, the time change detector 303 determines that the sixth to ninth pixels from the leftmost belong to the uncovered background area.
Since the pixel in the frame #n of the binary object image is 1, the corresponding pixel in the frame #n−1 is 1 and the corresponding pixel in the frame #n+1 is 1, the time change detector 303 determines that the tenth to thirteenth pixels from the leftmost belong to the foreground area.
Since the pixel in the frame #n of the binary object image is 1 and the corresponding pixel in the frame #n−1 is 0, the time change detector 303 determines that the fourteenth to seventeenth pixels from the leftmost belong to the covered background area.
Since the corresponding pixel in the frame #n of the binary object image is 0, the time change detector 303 determines that the eighteenth to twenty first pixels from the leftmost belong to the background area.
Next, referring to a flowchart of
In step S302, the binary object image extracting portion 302 calculates the correlation value between the input image and the background image supplied from the background image generator 301, for example, by using calculations which were explained by referring to
In step S304, the time change detector 303 performs the area determining processing to complete the processing.
Referring to a flowchart of
In step S321, if it is determined that the indicated pixel in the frame #n is 1, the procedure proceeds to step S323. The area determining portion 342 of the time change detector 303 determines whether the indicated pixel in the frame #n stored in the frame memory 341 is 1 and the corresponding pixel in the frame #n−1 is 0 or not, and if it is determined that the indicated pixel in the frame #n is 1 and the corresponding pixel in the frame #n−1 is 0, the procedure proceeds to step S324. Then, the area determining portion 342 determines that the indicated pixel in the frame #n belongs to the covered background area to finish the processing.
In step S323, if it is determined that the indicated pixel in the frame #n is 0 or the corresponding pixel in the frame #n−1 is 1, the procedure proceeds to step S325. The area determining portion 342 of the time change detector 303 determines whether the indicated pixel in the frame #n stored in the frame memory 341 is 1 and the corresponding pixel in the frame #n+1 is 0 or not, and if it is determined that the noticed pixel in the frame #n is 1 and the corresponding pixel in the frame #n+1 is 0, the procedure proceeds to step S326. Then, the area determining portion 342 determines that the indicated pixel in the frame #n belongs to the uncovered background area and finishes the processing.
In step S325, if it is determined that the indicated pixel in the frame #n is 0 or the corresponding pixel in the frame #n+1 is 1, the procedure proceeds to step S327. The area determining portion 342 of the time change detector 303 determines that the noticed pixel in the frame #n belongs to the foreground area and finishes the processing.
Like the above, the area specifying unit 103 can specify which of the foreground area, the background area, the covered background area and the uncovered background area that the pixels of the input image belong on the basis of the correlation value between the input image and the corresponding background image, and generates the area information corresponding to the specification result.
A robust processing portion 361 generates a binary object image of which robust processing is performed on the basis of the binary object image of N frames supplied from the binary object image extracting portion 302 and outputs it to the time change detector 303.
Referring to examples of
The switch 382 outputs the binary object image of the first frame in which motion is compensated to the frame memory 383-1 and outputs the binary object image, of the second frame in which motion is compensated to the frame memory 383-2. Similarly, the switch 382 outputs each of the binary object images of the third to N−1-th frames in which motion is compensated to one of the frame memory 383-3 to 383-(N−1) and outputs the binary object image of the Nth frame in which motion is compensated to the frame memory 383-N.
The frame memory 383-1 stores the binary object image of the first frame in which motion is compensated and outputs the stored binary object image to the weighting portion 384-1. The frame memory 383-2 stores the binary object image of the second frame in which motion is compensated and outputs the stored binary object image to the weighting portion 384-2.
Similarly, each of the frame memory 383-3 to 383-(N−1) stores one of the binary object images of the third to (N−1)th frames of which motion is compensated and outputs the stored binary object image to one of weighting portions 384-3 to 384-(N−1). The frame memory 383-N stores the binary object image of Nth frame of which motion is compensated and outputs the stored binary object image to the weighting portion 384-N.
The weighting portion 384-1 multiplies the binary object image of the first frame supplied from the frame memory 383-1 of which motion is compensated, by predetermined weight w1 to supply it to the accumulator 385. The weighting portion 384-2 multiplies the pixel value of the binary object image of the second frame supplied from the frame memory 383-2 of which motion is compensated by a predetermined weight w2 to supply it to the accumulator 385.
Similarly, each of the weighting portion 384-3 to the weighting portion 384-(N−1) multiplies the pixel value of the binary object image of one of the third to (N−1)th frames supplied from one of the frame memories 383-3 to 383-(N−1) of which motion is compensated, by one of weight w3 to weight w(N−1) to supply it to the accumulator 385. The weighting portion 384-N multiplies the pixel value of the binary object image of the Nth frame supplied from the frame memory 383-N of which motion is compensated, by a predetermined weight wN to supply it to the accumulator 385.
The accumulator 385 accumulates the pixel values corresponding to the binary object images of the first to Nth frames respectively multiplied by one of the weights w1 to wN of which motions are compensated and generates the binary object image by comparing the accumulated pixel values with the predetermined threshold value th0.
Like the above, since the robust processing portion 361 generates the binary object images of which robust processing is performed from N binary object images and supplies it to the time change detector 303, even when noises are included in the input image, the area specifying unit 103 of which the configuration is shown in

In step S344, the robust processing portion 361 performs the robust processing.
In step S345, the time change detector 303 performs the area specifying process and finishes the procedure. Since the detailed process in step S345 is similar to the process explained by referring to the flowchart of
Next, referring to a flowchart of
In step S363, the robust processing portion 361 determines whether N binary object images are stored or not and if it is determined that N binary object images are not stored, the procedure returns to step S361 and the motion compensating process for the binary object image and the storing process for the binary object image are repeated. In step S363, if it is determined that N binary object images are stored, the procedure proceeds to step S364. Each of the weighting portions 384-1 to 384-N multiplies each of the N binary object images by one of the weights w1 to wN for weighting.
In step S365, an accumulator 385 accumulates the weighted N binary object images.
In step S366, the accumulator 385 generates a binary object image from the accumulated image, for example, by comparing to the predetermined threshold value th1 and finishes the procedure.
Like the above, the area specifying unit 103 of which the configuration is shown in
As described above, the area specifying unit 103 can generate the area information indicating that each pixel included in the frame belongs to the moving area, the stationary area, the uncovered background area or the covered background area.
An estimated mixture ratio processor 402 calculates the mixture ratio of each pixel by using the calculation corresponding to the model of the uncovered background area on the basis of the input image and supplies the calculated estimated mixture ratio to the mixture ratio determining portion 403.
Since it is supposed that the object corresponding to the foreground is moving at a uniform speed for the shutter time, the mixture ratio α of pixel belonging to the mixed area has the following feature. That is, the mixture ratio α is linearly varied corresponding to the positional variation of a pixel. If the positional variation of a pixel is one-dimensional, the variation in mixture ratio α can be expressed by a linear line and if the positional variation of pixel is two-dimensional, the variation in mixture ratio α can be expressed by a plane.
Further, since time interval for one frame is short, it can be supposed that the object corresponding to the foreground is a rigid body and is moving at a uniform speed.
In this case, the slope of mixture ratio α is reciprocal ratio to the amount of movement v in the shutter time of the foreground.
An example of an ideal mixture ratio α is shown in
As shown in
In the example of
In equation (8), the pixel value C06 is expressed as the pixel value M of pixel in the mixed area and the pixel value P06 is expressed as the pixel value B of pixel in the background area. That is, the pixel value M of pixel in the mixed area and the pixel value B of pixel in the background area can be expressed by equation (9) and equation (10), respectively.
M=C06 (9)
B=P06 (10)
2/v in equation (8) corresponds to the mixture ratio α. Since the amount of movement v is defined as 4, the mixture ratio α of the seventh pixel from the leftmost in the frame #n is 0.5.
As described above, by considering the pixel value C in the indicated frame #n as the pixel value in the mixed area and the pixel value P in the frame #n−1 ahead of the frame #n as the pixel value in the background area, the equation (3) expressing the mixture ratio α can be expressed by equation (11).
C=α·P+f (11)
f in equation (11) is sum ΣiFi/v of the foreground components included in the indicated pixel. Variables included in equation (11) are two of the mixture ratio α and the sum f of the foreground components.
Similarly, in the uncovered background area, the amount of movement v is 4 and the virtual division number in the time direction is 4. A model in which the pixel values are expanded in the time direction is shown in
In the uncovered background area, similar to the expressions of the aforementioned covered background area, by considering the pixel value C of pixel in the indicated frame #n as the pixel value in the mixed area and the pixel value N in the frame #n+1 behind the frame #n as the pixel value in the background area, the equation (3) expressing the mixture ratio α can be expressed by equation (12).
C=α·N+f (12)
Further, although it has been explained by considering that the background object is stationary, even when the background object is moving, equation (8) to equation (12) can be applied by using the pixel value of pixel at a position corresponding to the amount of movement v of the background. For example, in
Since each of equation (11) and equation (12) includes two variables, the mixture ratio α cannot be obtained by these equations. Here, since the image has a strong correlation in space, the adjacent pixels are almost equal.
Therefore, because the foreground components have a strong correlation in space, by changing the equations to derive the sum f of the foreground components from the front or next frame, the mixture ratio α is obtained.
The pixel value Mc of the seventh pixel from the leftmost in the frame #n in
2/v of the first term of right side of equation (13) corresponds to the mixture ratio α. The second term of right side of equation (13) can be expressed by equation (14) using the pixel value in the next frame #n+1.
Here, using the spatial correlation of the foreground components, equation (15) can be obtained.
F=F05=F06=F07=F08=F09=F10=F11=F12 (15)
Equation (14) can be replaced with equation (16) by using equation (15).
Consequently, β can be expressed by equation (17).
β=2/4 (17)
In general, if it is supposed that the foreground components corresponding to the mixed area as shown in equation (15) are equal, equation (18) can be established for all the pixels in the mixed area, in view of relation of the interior division ratio.
β=1−α (18)
If the equation (18) is established, equation (11) can be obtained as shown in equation (19).
Similarly, if the equation (18) is established, equation (12) can be obtained as shown in equation (20).
In equation (19) and equation (20), since C, N and P are the known pixel values, the only variable in equation (19) and equation (20) is the mixture ratio α. The relationship of C, N and P in equation (19) and equation (20) is shown in
Therefore, since one variable is included respectively in equation (19) and equation (20), the mixture ratio α can be calculated using the pixel values of pixels in three frames. Conditions for calculating appropriate mixture ratio by solving equation (19) and equation (20) is that the pixel values of pixels are constant, the foreground components corresponding to the mixed area are equal, that is, the pixels being located on the interface of the image object corresponding to the moving direction of the foreground object in the foreground image object picked up when the foreground object is stationary, a twice number of pixels for the amount of movement v are adjacent in a row.
As described above, the mixture ratio α of pixels belonging to the covered background area is calculated by equation (21) and the mixture ratio α of pixels belonging to the uncovered background area is calculated by equation (22).
α=(C−N)/(P−N) (21)
α=(C−P)/(N−P) (22)
The frame memory 422 stores the input image in frame unit and supplies the frame one behind the frame supplied from the frame memory 421, to the mixture ratio calculator 423.
Therefore, when the frame #n+1 as the input image is input to the mixture ratio calculator 423, the frame memory 421 supplies the frame #n to the mixture ratio calculator 423 and the frame memory 422 supplies the frame #n−1 to the mixture ratio calculator 423.
The mixture ratio calculator 423 calculates the estimated mixture ratio of the noticed pixels by using calculation shown in equation (21) on the basis of the pixel value C of the indicated pixel in the frame #n, the pixel value N of pixel in the frame #n+1 of which the spatial position corresponds to that of the indicated pixel, and on the basis of the pixel value P of pixel in the frame #n−1 of which the spatial position corresponds to that of the indicated pixel, and outputs the calculated estimated mixture ratio. For example, when the background is stationary, the mixture ratio calculator 423 calculates the estimated mixture ratio of the indicated pixel on the basis of the pixel value C of the indicated pixel in the frame #n, the pixel value N of pixel in the frame #n+1 of which the position is equal to that of the indicated pixel, and the pixel value P of pixel in the frame #n−1 of which the position is equal to that of the indicated pixel, and outputs the calculated estimated mixture ratio.
Like the above, the estimated mixture ratio processor 401 can calculate the estimated mixture ratio on the basis of the input image and supply it to the mixture ratio determining portion 403.
Further, since the estimated mixture ratio processor 402 has the same function as the estimated mixture ratio processor 401, except that the estimated mixture ratio processor 402 calculates the estimated mixture ratio of the indicated pixel by using calculation expressed by equation (22), on the contrary to the estimated mixture ratio processor 401 which calculates the estimated mixture ratio of the indicated pixel by using calculation expressed by equation (21), explanation thereof will be omitted.
It can be known that the estimated mixture ratio is almost linearly varied, as shown in the mixed area of
Returning to
The estimated mixture ratio processor 442 calculates the estimated mixture ratio of the indicated pixel belonging to the covered background area by using calculation by equation (21) on the basis of the pixel value input from the selector 441, and supplies the calculated estimated mixture ratio to a selector 444.
The estimated mixture ratio processing portion 443 calculates the estimated mixture ratio of the indicated pixel belonging to the uncovered background area by using calculation by equation (22) on the basis of the pixel value input from the selector 441, and supplies the calculated estimated mixture ratio to a selector 444.
When the target pixel belongs to the foreground area, the selector 444 selects the estimated mixture ratio of 0 on the basis of the area information supplied from the area specifying unit 103, and sets it to the mixture ratio α and when the target pixel belongs to the background area, the selector 444 selects the estimated mixture ratio of 1 and sets it to the mixture ratio α. When the target pixel belongs to the covered background area, the selector 444 selects the estimated mixture ratio supplied from the estimated mixture ratio processor 442 to set it to the mixture ratio α. When the target pixel belongs to the uncovered background area, the selector 444 selects the estimated mixture ratio supplied from the estimated mixture ratio processor 443 to set it to the mixture ratio α. The selector 444 outputs the mixture ratio α selected and set on the basis of the area information.
Like the above, the mixture ratio calculator 104 having another configuration shown in
Referring to a flowchart of
In step S403, the estimated mixture ratio processor 402 performs the estimated mixture ratio calculating process by using a model corresponding to the uncovered background area and supplies the calculated estimated mixture ratio to the mixture ratio determining portion 403.
In step S404, the mixture ratio calculator 104 determines whether the mixture ratios α are estimated for the whole frame or not, and if it is determined that the mixture ratios α are not estimated for the whole frames, the procedure returns to step S402 and performs processing of estimating the mixture ratio α for next pixel.
In step S404, if it is determined that the mixture ratio α is estimated for the whole frame, the procedure proceeds to step S405 and the mixture ratio determining portion 403 sets the mixture ratio α on the basis of the area information supplied from the area specifying unit 103, indicating which of the foreground area, the background area, the covered background area and the uncovered background area the pixel belongs to. The mixture ratio determining portion 403 sets 0 to the mixture ratio α when the target pixel belongs to the foreground area, sets 1 to the mixture ratio α when the target pixel belongs to the background area, sets the estimated mixture ratio supplied from the estimated mixture ratio processor 401 to the mixture ratio α when the target pixel belongs to the covered background area and sets the estimated mixture ratio supplied from the estimated mixture ratio processor 402 to the mixture ratio α when the target pixel belongs to the uncovered background area. Then, the process ends.
Like the above, the mixture ratio calculator 104 can calculate the mixture ratio α that is a feature amount corresponding to each pixel, on the basis of the area information supplied from the area specifying unit 103 and the input image.
The mixture ratio α calculation processing of the mixture ratio calculator 104 of which configuration is shown in
Next, a process of estimating a mixture ratio by using a model corresponding to the covered background area, corresponding to step S402 in
In step S421, the mixture ratio calculator 423 obtains the pixel value C of the indicated pixel in the frame #n from the frame memory 421.
In step S422, the mixture ratio calculator 423 obtains the pixel value P of pixel in the frame #n−1 corresponding to the indicated pixel from the frame memory 422.
In step S423, the mixture ratio calculator 423 obtains the pixel value N of pixel in the frame #n+1 corresponding to the indicated pixel included in the input image.
In step S424, the mixture ratio calculator 423 calculates the estimated mixture ratio on the basis of the pixel value C of the indicated pixel in the frame #n, the pixel value P of pixel in the frame #n−1 and the pixel value N of pixel in the frame #n+1.
In step S425, the mixture ratio calculator 423 determines whether the estimated mixture ratio calculation processing is finished for the whole frame or not and if it is determined that the estimated mixture ratio calculation processing is not finished for the whole frame, the procedure returns to step S421 and repeats the estimated mixture ratio calculation processing for next pixel.
In step S425, if it is determined that the estimated mixture ratio calculating processing is finished for the whole frame, the process ends.
Like this, the estimated mixture ratio processor 401 can calculate the estimated mixture ratio on the basis of the input image.
The mixture ratio estimating process by using a model corresponding to the uncovered background area in step S403 in
Further, since the estimated mixture ratio processor 442 and the estimated mixture ratio processor 443 shown in
Further, although it has been explained that the object corresponding to the background is stationary, even when the image corresponding to the background area includes motion, the mixture ratio α calculating process mentioned above can be applied. For example, when the image corresponding to the background area is constantly moving, the estimated mixture ratio processor 401 shifts the whole image according to motion of the background, and performs the same processing as in the case where the object corresponding to the background is stationary. Further, when the image corresponding to the background area includes local motion of other background, the estimated mixture ratio processor 401 selects the pixels corresponding to the motion of the background as the pixels corresponding to the pixels belonging to the mixed area, and performs the aforementioned process.
Further, the mixture ratio calculator 104 may perform the mixture ratio estimating processing for all the pixels by only using a model corresponding to the covered background area, and may output the calculated estimated mixture ratio as the mixture ratio α. In this case, the mixture ratio α means the ratio of the background components for the pixels belonging to the covered background area and the ratio of the foreground components for the pixels belonging to the uncovered background area. If the absolute value of the difference between the mixture ratio α is calculated like the above method and 1 for the pixels belonging to the uncovered background area and the calculated absolute value is set to the mixture ratio α, the separation server 11 can obtain the mixture ratio α indicating the ratio of the background components for the pixels belonging to the uncovered background area.
Further, similarly, the mixture ratio calculator 104 may perform only the mixture ratio estimating processing for all the pixels by using a model corresponding to the uncovered background area, and may output the calculated estimated mixture ratio as the mixture ratio α.
Next, the mixture ratio calculator 104 for calculating the mixture ratio α by using characteristics that the mixture ratio α is varied linearly will be explained.
As described above, since each of equation (11) and equation (12) includes two variables, the mixture ratio α cannot be obtained from these equations.
Therefore, equation approximating the mixture ratio α and sum f of the foreground components in the spatial direction is established by using characteristics that the mixture ratio α is varied linearly corresponding to the positional variation of pixels according to movement of the foreground object at a uniform speed for the shutter time. The equation approximating the mixture ratio α and sum f of the foreground components is solved by using the pixel value of pixel belonging to the mixed area and the pixel value of pixel belonging to the background area.
If variation of the mixture ratio α is linearly approximated, the mixture ratio α is expressed by equation (23).
α=il+p (23)
In this equation (23), i is an index in the spatial direction when the position of the indicated pixel is 0. l is slope of a linear line of the mixture ratio α. p is an intercept of the linear line of the mixture ratio α and is the mixture ratio α of the indicated pixel. In equation (23), the index i is known but the slope l and the intercept p are not known.
The relationship between index i, the slope l and the intercept p is shown in
By approximating the mixture ratio α by equation (23), a plurality of different mixture ratios α for a plurality of pixels are expressed with two variables. In the example shown in
If the mixture ratio α is approximated in a plane shown in
α=jm+kq+p (24)
In equation (24), j is an index in the horizontal direction when the position of the indicated pixel is 0 and k is an index in the vertical direction. m is a slope of the mixture ratio α plane in the horizontal direction and q is a slope of the mixture ratio α plane in the vertical direction. p is an intercept of the mixture ratio α plane.
For example, in the frame #n shown in
C05=α05·B05/v+f05 (25)
C06=α06·B06/v+f06 (26)
C07=α07·B07/v+f07 (27)
If the foreground components are equal in the neighborhood, that is, F01 to F03 are equal and F01 to F03 is replaced with Fc, equation (28) can be established.
f(x)=(1−α(x)]·Fc (28)
In equation (28), x expresses a position of the spatial direction.
If α (x) is replaced with equation (24), and equation (28) can be expressed by equation (29).
In equation (29), (−m·Fc), (−q·Fc) and (1−p)·Fc are replaced as shown in equations (30) to (32).
s=−m·Fc (30)
t=−q·Fc (31)
u=(1−p)·Fc (32)
In equation (29), j is an index in the horizontal direction when position of the indicated pixel is 0 and k is an index in the vertical direction.
Like the above, since it is supposed that the object corresponding to the foreground is moving at a uniform speed for the shutter time and the components corresponding to the foreground are constant in the neighborhood, the sum of the foreground components is approximated by equation (29).
Further, when the mixture ratio α is approximated by a linear line, the sum of the foreground components can be expressed by equation (33).
f(x)=is+u (33)
If substituting the mixture ratio α in equation (13) and the sum of the foreground components in equation (24) and equation (29), the pixel value M is expressed by equation (34).
In equation (34), the six unknown variables are the slope m of the mixture ratio α plane in the horizontal direction, the slope q of the mixture ratio α plane in the vertical direction and the intercepts p, s, t and u of the mixture ratio α plane.
The pixel value M or the pixel value B is substituted in a normal equation shown in equation (34) corresponding to pixels in the neighborhood of the indicated pixel and a plurality of normal equations in which the pixel value M or the pixel value B is substituted are solved by the least square method to calculate the mixture ratio α.
For example, if the index j of the indicated pixel in the horizontal direction is 0, the index k in the vertical direction is 0 and the pixel value M or the pixel value B is substituted in the normal equation shown in equation (34) for 3×3 pixels adjacent to the indicated pixel, equations (35) to (43) are obtained.
M−1, −1=(−1)·B−1, −1·m+(−1)·B−1, −1·q+B−1, −1·p+(−1)·s+(−1)·t+u (35)

M0, +1=(0)·B0, +1·m+(+1)·B0, +1·q+B0, +1·p+(0)·s+(+1)·t+u (42)
M+1, +1=(+1)·B+1, +1·m+(+1)·B+1, +1·q+B+1, +1·p+(+1)·s+(+1)·t+u (43)
Since the index j of the indicated pixel in the horizontal direction is 0 and the index k in the vertical direction is 0, the mixture ratio α of the indicated pixel is equal to the value when j=0 and k=0 in equation (24), that is, the intercept p.
Therefore, each value of the slope m in the horizontal direction, the slope q in the vertical direction and the intercepts p, s, t and u is calculated by using the least square method on the basis the nine equations (35) to (43) and then, the intercept p is output as the mixture ratio α.
Next, a more specific procedure for calculating the mixture ratio α by using the least square method will be explained.
If the index i and the index k are expressed by one index x, the relationship of the index i, the index k and the index x is expressed by equation (44).
x=(j+1)·3+(k+1) (44)
The slope m in the horizontal direction, the slope q in the vertical direction and the intercepts p, s, t, and u are expressed as variables w0, w1, w2, w3, w4 and w5, respectively and jB, kB, B, j, k and l are expressed as a0, a1, a2, a3, a4 and a5, respectively. Considering error ex, equations (35) to (43) can be rewritten as equation (45).
In equation (45), x is a value from integers 0 to 8.
Equation (46) can be derived from the equation (45).
Here, in order to use the least square method, the sum of squares of errors E is defined as shown by equation (47).
In order to minimize error, the partial differential of variable Wv and the sum of squares of errors E should be 0. Here, v is one of integers 0 to 5. Therefore, wy is obtained to satisfy equation (48).
If equation (46) is substituted in equation (48), equation (49) is obtained.
By applying, for example, sweeping-out method such as Gauss-Jordan elimination method, to six equations obtained by substituting one of integers 0 to 5 in v of equation (49), wy is calculated. As described above, w0 is the slope m in the horizontal direction, w1 is the slope in the vertical direction, w2 is the intercept p, w3 is s, w4 is t and w5 is u.
As described above, by applying the least square method to equations in which the pixel value M and the pixel value B are substituted, the slope m in the horizontal direction, the slope q in the vertical direction and the intercepts p, s, t and u can be obtained.
In explanation of equations (35) to (43), the pixel value of pixel included in the mixed area is explained as M and the pixel value of pixel included in the background area is explained as B. However, it is necessary that normal equations be established for each case that the indicated pixel is included in the covered background area or in the uncovered background area.
For example, when the mixture ratios α of pixels included in the covered background area in the frame #n as shown in
When the mixture ratios α of pixels included in the uncovered background area in the frame #n as shown in
Further, for example, when the mixture ratios α of pixels included in the covered background area in the frame #n as shown in

Mc9=(+1)·Bc9·m+(+1)·Bc9·q+Bc9·p+(+1)·s+(+1)·t+u (58)
When the mixture ratios α of pixels included in the covered background area in the frame #n are calculated, the pixel values Bc1 to Bc9 of pixels of the background area in the frame #n−1 corresponding to the pixels in the frame #n are used in equations (50) to (58).
When the mixture ratios α of pixels included in the uncovered background shown in

Mu9=(+1)·Bu9·m+(+1)·Bu9·q+Bu9·p+(+1)·s+(+1)·t+u (67)
When the mixture ratios α of pixels included in the uncovered background area in the frame #n are calculated, the pixel values Bu1 to Bu9 of pixels of the background area in the frame #n+1 corresponding to the pixels in the frame #n are used in equations (59) to (67).
The delay circuit 501 delays the input image by one, frame and supplies it to the adder 502. When the frame #n is input to the adder 502 as the input image, the delay circuit 501 supplies the frame #n−1 to the adder 502.
The adder 502 sets the pixel values of pixels adjacent to pixel of which the mixture ratio α is calculated and the pixel values in the frame #n−1 in the normal equations. For example, the adder 502 sets the pixel values Mc1 to Mc9 and the pixel values Bc1 to Bc9 in the normal equations on the basis of equations (50) to (58). The adder 502 supplies the normal equations in which the pixel values are set to the calculator 503.
The calculator 503 solves the normal equations supplied from the adder 502 by using the elimination method, etc. to obtain the estimated mixture ratio and outputs the obtained estimated mixture ratio.
Like the above, the estimated mixture ratio processor 401 can calculate the estimated mixture ratio on the basis of the input image and supply it to the mixture ratio determining portion 403.
Further, since the estimated mixture ratio processor 402 has the configuration similar to that of the estimated mixture ratio processor 401, explanation thereof will be omitted.
It can be known that the estimated mixture ratio is varied almost linearly in the mixed area as shown in
Next, the mixture ratio estimating processing of the estimated mixture ratio processor 401 of which configuration is shown in
In step S521, the adder 502 sets the pixel values included in the input image and the pixel values included in the image supplied from the delay circuit 501 in the normal equations corresponding to the model of the covered background area.
In step S522, the estimated mixture ratio processor 401 determines whether setting for the target pixels is finished or not and if it is determined that the setting for the target pixels is not finished, the procedure returns to step S521 and repeats the setting processing of the pixel values in the normal equations.
In step S522, if it is determined that the setting the pixel value for the target pixels is finished, the procedure proceeds to step S523 and the calculator 173 calculates the estimated mixture ratio on the basis of the normal equations in which the pixel values are set and outputs the obtained estimated mixture ratio.
Like the above, the estimated mixture ratio processor 401 of which configuration is shown in
The mixture ratio estimating process using the model corresponding to the uncovered background area is similar to the process using the normal equations corresponding to the model of the uncovered background area shown in a flowchart of
Further, although it has been explained that the object corresponding to the background is stationary, even when the image corresponding to the background area includes movement, the aforementioned mixture ratio obtaining processing can be applied. For example, when the image corresponding to the background is moving constantly, the estimated mixture ratio processor 401 shifts the whole image according to the movements and then, processes similarly to the case that the object corresponding to the background is stationary. Further, when the image corresponding to the background area includes other local movements, the estimated mixture ratio processing portion 401 selects the pixels corresponding to the movements as the pixels corresponding to pixels belonging to the mixed area and then, performs the aforementioned processing.
Like the above, the mixture ratio calculator 102 can calculate the mixture ratio α that is a feature amount corresponding to each pixel on the basis of the area information supplied from the area specifying unit 101 and the input image.
By using the mixture ratio α, while the information of motion blur included in the image corresponding to the moving object is left, it is possible to separate the foreground components and the background components included in the pixel values.
Further, if an image is synthesized on the basis of the mixture ratio α, it is possible to generate image including the corrected motion blur adapted to the speed of the object moving to correspond to the images in the real world.
Next, the foreground/background separator 105 will be explained.
The mixture ratio α supplied from the mixture ratio calculator 104 is supplied to the separating portion 601.
The separating portion 601 separates the foreground components from the input image to supply the separated foreground components to the synthesizer 603 and separates the background components from the input image to supply the separated background components to the synthesizer 605, on the basis of the area information indicating the covered background area, the area information indicating the uncovered background area and the mixture ratio α.
When the pixels corresponding to the foreground are input, the switch 602 is closed and supplies only the pixels corresponding to the foreground included in the input image to the synthesizer 603, on the basis of the area information indicating the foreground area.
When the pixels corresponding to the background are input, the switch 604 is closed and supplies only the pixels corresponding to the background included in the input image to the synthesizer 605, on the basis of the area information indicating the background area.
The synthesizer 603 synthesizes the foreground component image on the basis of the foreground components supplied from the separating portion 601 and the pixels corresponding to the foreground supplied from the switch 602, and outputs the synthesized foreground component image. Since the foreground area and the background area are not overlapped, the synthesizer 603 applies, for example, logical sum operation to the foreground components and the pixels corresponding to the foreground to synthesize the foreground component image.
In initial process to be first performed in the process of synthesizing the foreground component image, the synthesizer 603 stores the image of which all the pixels in the built-in frame memory are 0, and in the process of synthesizing the foreground component image, the synthesizer 603 stores (overwrites) the foreground component image. Therefore, 0 is stored as the pixel values in the pixels corresponding to the background area and in the foreground component images supplied from the synthesizer 603.
The synthesizer 605 synthesizes the background component image on the basis of the background components supplied from the separating portion 601 and the pixels corresponding to the background supplied from, the switch 604, and outputs the synthesized background component image. Since the background area and the mixed area are not overlapped, the synthesizer 605 applies, for example, logical sum operation to the background components and the pixels corresponding to the background to synthesize the background component image.
In initial process to be first performed in the process of synthesizing the background component image, the synthesizer 605 stores the image of which all the pixels in the built-in frame memory are 0, and in the process of synthesizing the background component image, the synthesizer 605 stores (overwrites) the background component image. Therefore, 0 is stored as the pixel values in the pixels corresponding to the foreground area and in the background component images supplied from the synthesizer 605.
As shown in
As shown in
The pixel values of pixels in the mixed area are separated into the background components and the foreground components by the foreground/background separator 105. The separated background components constitute the background component image along with the pixels belonging to the background area. The separated foreground components constitute the foreground component image along with the pixels belonging to the foreground area.
Like the above, in the foreground component image, the pixel values of pixels corresponding to the background area are 0, and significant pixel values are set to the pixels corresponding to the foreground area and the pixels corresponding to the mixed area. Similarly, in the background component image, the pixel values of pixels corresponding to the foreground area are 0, and significant pixel values are set to the pixels corresponding to the background area and the pixels corresponding to the mixed area.
Next, a process of separating the foreground components and the background components from the pixels belonging to the mixed area, to be performed by the separating portion 601 will be explained.
In a frame #n, the leftmost pixel and the fourteenth to eighteenth pixels from the leftmost include only the background components and belong to the background area. In the frame #n, the second to fourth pixels from the leftmost include the background components and the foreground components and belong to the uncovered background area. In the frame #n, the eleventh to thirteenth pixels from the leftmost include the background components and the foreground components and belong to the covered background area. In the frame #n, the fifth to tenth pixels from the leftmost include only the foreground components and belong to the foreground area.
In a frame #n+1, the first to fifth pixels from the leftmost and the eighteenth pixel from the leftmost include only the background components and belong to the background area. In the frame #n+1, the sixth to eighth pixels from the leftmost include the background components and the foreground components and belong to the uncovered background area. In the frame #n+1, the fifteenth to seventeenth pixels from the leftmost include the background components and the foreground components and belong to the covered background area. In the frame #n+1, the ninth to fourteenth pixels from the leftmost include only the foreground components and belong to the foreground area.
The pixel value C15 of the fifteenth pixel from the leftmost in the frame #n is expressed by equation (68).
Here, α15 is a mixture ratio of the fifteenth pixel from the leftmost in the frame #n. P15 is a pixel value of the fifteenth pixel from the leftmost in the frame #n−1.
On the basis of equation (68), sum f15 of the foreground components of the fifteenth pixel from the leftmost in the frame #n is expressed by equation (69).
Similarly, sum f16 of the foreground components of the sixteenth pixel from the leftmost in the frame #n is expressed by equation (70), and sum f17 of the foreground components of the seventeenth pixel from the leftmost in the frame #n is expressed by equation (71).
f16=C16−α16·P16 (70)
f17=C17−α17·P17 (71)
Like the above, the foreground component fc included in the pixel value C of pixels belonging to the covered background area is calculated by equation (72).
fc=C−α·P (72)
P is the pixel value of the corresponding pixel in the frame one ahead.
The pixel value C02 of the second pixel from the leftmost in the frame #n is expressed by equation (73).
Here, α2 is the mixture ratio of the second pixel from the leftmost in the frame #n. N02 is the pixel value of the second pixel from the leftmost in the frame #n+1.
On the basis of equation (73), sum f02 of the foreground components of the second pixel from the leftmost in the frame #n is expressed by equation (74).
Similarly, sum f03 of the foreground components of the third pixel from the leftmost in the frame #n is expressed by equation (75) and sum f04 of the foreground components of the fourth pixel from the leftmost in the frame #n is expressed by equation (76)
f03=C03−α3·N03 (75)
f04=C04−α4·N04 (76)
Like this, the foreground component fu included in the pixel value C of pixel belonging to the uncovered background area is calculated by equation (77).
fu=C−α (77)
N is the pixel value of the corresponding pixel in the frame one behind.
Like the above, the separating portion 601 can separate the foreground components and the background components from the pixel belonging to the mixed area on the basis of the information indicating the covered background area, the information indicating the uncovered background area which are included in the area information and the mixture ratio α for each pixel.
The frame memory 621 stores the input image in frame unit. When the target of processing is the frame #n, the frame memory 621 stores the frame #n−1 one ahead of the frame #n the frame #n and the frame #n+1 one behind the frame #n.
The frame memory 621 supplies pixels corresponding to the frame #n−1, the frame #n and the frame #n+1 to the separation processing block 622.
The separation processing block 622 separates the foreground component and background component from the pixel belonging to the mixed area of the frame #n on the basis of the area information indicating the covered background area and the uncovered background area and the mixture ratio α by applying the pixel values of the pixels corresponding to the frame #n−1, the frame #n and the frame #n+1, supplied from the frame memory 621 by the calculation explained in
The separation processing block 622 comprises an uncovered-area processor 631, a covered-area processor 632, a synthesizer 633 and synthesizer 634.
A multiplier 641 of the uncovered-area processor 631 multiplies the pixel value of the pixel in the frame #n+1 supplied from the frame memory 621 by the mixture ratio α and outputs the result to the switch 642. The switch 642 is closed when the pixel in the frame #n supplied from the frame memory 621 (corresponding to the pixel of the frame #n+1) belongs to the uncovered background area, and supplies the value obtained by multiplying the pixel value by the mixture ratio α supplied from the multiplier 641 to the calculator 643 and the synthesizer 634. The value obtained by multiplying the pixel value of the pixel in the frame #n+1 output from the switch 642 by the mixture ratio α equals to the background component of the pixel value of the pixel corresponding to the frame #n.
The calculator 643 obtains the foreground component by subtracting the background component which is supplied from the switch 642 from the pixel value of the pixel of the frame #n which is supplied from the frame memory 621, and supplies the foreground component of the pixel of the frame #n belonging to the uncovered background area to the synthesizer 633.
The multiplier 651 of the covered-area processor 632 multiplies the pixel value of the pixel of the frame #n−1 supplied from the frame memory 621 by the mixture α, and outputs the result to the switch 652. The switch 652 is closed when the pixel of frame #n which is supplied from the frame memory 621 (corresponding to the pixel of the frame #n−1) belongs to the covered background area, and supplies the value obtained by multiplying the pixel value by the mixture ratio α which is supplied from the multiplier 651 to the calculator 653 and the synthesizer 634. The value obtained by multiplying the pixel value of the pixel of the frame #n−1 output from the switch 652 by the mixture ratio α equals to the background component of the pixel value of the pixel corresponding to the frame #n.
The calculator 653 obtains the foreground component by subtracting the background component which is supplied from switch 652 from the pixel value of the pixel of the frame #n which is supplied from the frame memory 621, and supplies the foreground component of the pixel of the frame #n belonging to the covered background area to the synthesizer 633.
The synthesizer 633 synthesizes the foreground component of the pixel of the frame #n, belonging to the uncovered background area and supplied from the calculator 643 and the foreground component of the pixel of the frame #n, belonging to the covered background area and supplied from the calculator 653, and then supplies the result to the frame memory 623.
The synthesizer 634 synthesizes the background component of the pixel of the frame #n, belonging to the uncovered background area and supplied from the switch 642 and the background component of the pixel of the frame #n, belonging to the covered background area and supplied from the calculator 652, and then supplies the result to the frame memory 623.
The frame memory 623 stores respectively the foreground component and the background component of the pixels of the mixed area of the frame #n which are supplied from the separation processing block 622.
The frame memory 623 outputs the stored foreground component and background component of the pixels of the mixed area of the frame #n.
It is possible to perfectly separate the foreground component from the background component which are included in the pixel value by using the mixture ratio α which is a feature amount.
The synthesizer 603 synthesizes the foreground component of the pixel of the mixed area of frame #n output from the separating portion 601 and the pixel belongs to the foreground area to generate the foreground component image. The synthesizer 605 synthesizes the background component of the pixel of the mixed area of frame #n output from the separating portion 601 and the pixel belongs to the background area to generate the background component image.
The second to fourth pixels from the leftmost belong to the uncovered background area before they are separated into the foreground and background. Therefore, their respective background components become 0 and their respective foreground components remain unchanged. The eleventh to thirteenth pixels from the leftmost belong to the covered background area before they are separated into the foreground and background. Therefore, their respective background components become 0 and their respective foreground components remain unchanged. Because the fifth to tenth pixel from the leftmost comprise only the foreground component, their respective pixel values remain unchanged.
The second to fourth pixels from the leftmost belong to the uncovered background area before they are separated into the foreground and background. Therefore, their respective foreground components become 0 and their respective background components remain unchanged. The eleventh to thirteenth pixels from the leftmost belong to the covered background area before they are separated into the foreground and background. Therefore, their respective foreground components become 0 and their respective background components remain unchanged. Because the fifth to tenth pixel from the leftmost comprise only the foreground component, their respective pixel values become 0.
Next, referring to a flowchart in
In step S602, the separation processing block 622 of the separating portion 601 obtains the area information supplied from the mixture ratio calculator 104. In step S603, the separation processing block 622 of the separating portion 601 obtains the mixture ratio α supplied from the mixture ratio calculator 104.
In step S604, the uncovered-area processor 631 extracts the background component from the pixel value of the pixel belonging to the uncovered background area supplied from the frame memory 621 on the basis of the area information and the mixture ratio α.
In step S605, the uncovered area processor 631 extracts the foreground component from the pixel value of the pixel belonging to the uncovered background area supplied from the frame memory 621 on the basis of the area information and the mixture ratio α.
In step S606, the covered area processor 632 extracts the background component from the pixel value of the pixel belonging to the covered background area supplied from the frame memory 621 on the basis of the area information and the mixture ratio α.
In step S607, the uncovered area processor 632 extracts the foreground component from the pixel value of the pixel belonging to the covered background area supplied from the frame memory 621 on the basis of the area information and the mixture ratio α.
In step S608, the synthesizer 633 synthesizes the foreground component of the pixel belonging to the uncovered background area and extracted from the processing in step S605 and the foreground component of the pixel belonging to the covered background area and extracted from the processing in step S607. The synthesized foreground component is supplied to the synthesizer 603. Further, the synthesizer 603 synthesizes the pixel belonging to the foreground area and supplied through the switch 602 and the foreground component supplied from the separating portion 601, and then generates the foreground component image.
In step S609, the synthesizer 634 synthesizes the background component of the pixel belonging to the uncovered background area and extracted from the processing in step S604 and the background component of the pixel belonging to the covered background area and extracted from the processing in step S606. The synthesized background component is supplied to the synthesizer 605. Further, the synthesizer 605 synthesizes the pixel belonging to the background area and supplied through the switch 604 and the background component supplied from the separating portion 601, and then generates the foreground component image.
In step S610, the synthesizer 603 outputs the foreground component image. In step S611, the synthesizer 605 outputs the background component image and then the process ends.
Like the above, the foreground/background separator 105 can separate the foreground component and the background component from the input image based on the area information and the mixture ratio α and output the foreground component image comprised of only the foreground component and the background component image comprised of only the background component.
Next, an adjustment process of adjusting the amount of motion blur of the foreground component image is explained.
The unit of processing determining portion 801 generates the unit of processing based on the motion vector, the positional information thereof and the area information, and then supplies the generated unit of processing to the model forming portion 802 and the adder 804.
The unit of processing A generated by the unit of processing determining portion 801, as shown in
The model forming portion 802 performs the model forming based on the motion vector and the input unit of processing A. More specifically, the model forming portion 802 stores, for example, a plurality of models corresponding to the number of pixels included in the unit of processing A, the virtual division number of pixel value in time direction and the number of the foreground components for each pixel in advance, and then selects a designated model corresponding to the pixel value and the foreground component shown in
For example, if the number of pixels of the unit of processing A is 12 and the amount of movement v in shutter time is 5, the model forming portion 802 selects a model totally comprised of 8 foreground components and where the virtual division number is 5, the leftmost pixel includes 1 foreground component, the second pixel from the leftmost includes 2 foreground components, the third pixel from the leftmost includes 3 foreground components, the fourth pixel from the leftmost includes 4 foreground components, the fifth pixel from the leftmost includes 5 foreground components, the sixth pixel from the leftmost includes 5 foreground components, the seventh pixel from the left includes 5 foreground components, the eighth pixel from the leftmost includes 5 foreground components, the ninth pixel from the leftmost includes 4 foreground components, the tenth pixel from the leftmost includes 3 foreground components, the eleventh pixel from the leftmost includes 2 foreground components, the twelfth pixel from the leftmost includes 1 foreground component.
Further, the model forming portion 802 may not select one of the models stored in advance, but may generate a model based on motion vector and the unit of processing when the motion vector and the unit of processing A are supplied.
The model forming portion 802 supplies the selected model to the equation generator 803.
The equation generator 803 generates equations based on the models supplied from the model forming portion 802. Referring to the models of the foreground component image in
When the foreground component included in the foreground component image corresponding to the shutter time/v lies between F01/v and F08/v, the relations between F01/v to F08/v and the pixel values C01 to C12 are expressed in equations (78) to (89).
C01=F01/v (78)
C02=F02/v+F01/v (79)
C03=F03/v+F02/v+F01/v (80)
C04=F04/v+F03/v+F02/v+F01/v (81)
C05=F05/v+F04/v+F03/v+F02/v+F01/v (82)
C06=F06/v+F05/v+F04/v+F03/v+F02/v (83)
C07=F07/v+F06/v+F05/v+F04/v+F03/v (84)
C08=F08/v+F07/v+F06/v+F05/v+F04/v (85)
C09=F08/v+F07/v+F06/v+F05/v (86)
C10=F08/v+F07/v+F06/v (87)
C11=F08/v+F07/v (88)
C12=F08/v (89)
The equation generator 803 generates equations by modifying the generated equations. Equations generated by the equation generator 803 are expressed in equations (90) to (101).
Equations (90) to (102) may be expressed as an equation (102).
In equation (102), j means the position of pixel. In this example, j is one of 1 to 12. Further, i means the position of foreground value. In this example, i is one of 1 to 8. aij is 0 or 1 according to the values of i and j.
Considering an error, equation (102) is expressed as equation (103).
In equation (103), ej is an error included in indicated pixel Cj.
Equation 103 can be expressed as equation 104 again.
Here, sum of the square of errors E is defined as shown in equation (105) to apply the least square method.
In order to minimize the error, the value of the partial differential by the variable Fk to the sum of the square of errors E should equal zero. Fk satisfying equation (106) is obtained.
In equation (106), because the amount of movement v is fixed, equation (107) can be derived.
Equation (108) is obtained by expanding and transposing equation (107).
Equation (108) is expanded in 8 equations obtained by substituting one of integers between 1 and 8 for k in equation (108). The obtained 8 equations can be expressed as a matrix equation, and this matrix equation is called a normal equation.
An example of a normal equation generated by the equation generator 803 based on the least square method is shown in equation (109).
If equation (109) is expressed as A·F=v·C, C, A and v are known and F is unknown. A and v are known at the time of model forming and C is already known by inputting the pixel values in adding operation.
Errors included in pixel C can be dispersed by calculating the foreground component by using the normal equation based on the least square method.
The equation generator 803 supplies the normal equation generated by the above to the adder 804.
The adder 804 sets the pixel values C included in foreground component image in the matrix equation supplied from the equation generator 803 on the basis of the unit of processing supplied from the unit of processing determining portion 801. The adder 804 supplies the matrix where the pixel values C are set to the calculator 805.
The calculator 805 calculates the foreground component Fi/v from which motion blur is eliminated through the processing based on the sweeping-out methods such as Gauss-Jordan elimination method, calculates Fi corresponding to the pixel value i of the foreground from which motion blur is eliminated, wherein i is one of integers between 0 and 8, and then outputs the foreground component image from which motion blur is eliminated, along with the calculated pixel value Fi to the motion blur adder 806 and the selector 807.
Further, as shown in
The motion blur adder 806 may adjust the amount of motion blur by adding the amount by which motion blur is adjusted v′ which is different from the amount of movement v, for example, the amount by which motion blur is adjusted v′ is half of the amount of movement v, or has no relation with the amount of movement v. For example, as shown in
The motion blur adder 806 supplies the foreground component image of which the amount of motion blur is adjusted to the selector 807.
The selector 807 selects one of the foreground component image from which motion blur is eliminated and which is supplied from the calculator 805 and the foreground component image of which the amount of motion blur is adjusted and which is supplied from the motion blur adder 806 on the basis of the selection signal selected by an user, and then outputs the selected foreground component image.
Like the above, the motion blur adjusting unit 106 is able to adjust the amount of motion blur based on the selection signal and the amount v′ by which motion blur is adjusted.
Further, for example, as shown in
The motion blur adjusting unit 106 generates as many equations needed to correspond to the length of the unit of processing and calculates the pixel value Fi from which the amount of motion blur is adjusted. In the same manner, when the number of pixels included in the unit of processing is, for example, 100, the motion blur adjusting unit 106 generates as many equations to accommodate the unit of processing comprising one hundred pixels, and then calculates Fi.
The selector 821 supplies the input motion vector and the positional information thereof, as it is, to the unit of processing determining portion 801 and the model forming portion 802, on the basis of the selection signal or replaces the magnitude of motion vector with the amount v′ by which motion blur is adjusted and then supplies the replaced amount v′ and the positional information thereof to the unit of processing determining portion 801 and the model forming portion 802.

The unit of processing determining portion 901 generates a unit of processing based on the motion vector and positional information thereof, and the area information, and then supplies the generated unit of processing to the model forming portion 902 along with the motion vector.
The model forming portion 902 performs the model forming based on the motion vector and the input unit of processing. More specifically, the model forming portion 902 stores, for example, a plurality of models corresponding to the number of pixels included in the unit of processing, the virtual division number of the pixel value in time direction and the number of the foreground components for each pixel in advance, selects a specifying model corresponding to the pixel value and the foreground component shown in

The equation generator 903 generates equations based on the model supplied from the model forming portion 902.
Referring to models of the foreground component image shown in
When the foreground component corresponding to (shutter time)/v included in the foreground component image is between F01/v and F08/v, the relationship between F01/v to F08/v and the pixel values C01 to C12 are expressed in equations (78) to (89) as mentioned earlier.
Paying attention to the pixel values C12 and C11, the pixel value C12 comprise only the foreground component F08/v as shown in equation (111) and the pixel value C11 comprise the sum of the foreground components F08/v and F07/v. Therefore, the foreground component F07/v can be obtained from equation (112).
F08/v=C12 (111)
F07/v=C11−C12 (112)
In the same manner, referring to the foreground components included in the pixel values C10 to C01, the foreground components F06/v to F01/v can be obtained by the equations (113) to (118).
F06/v=C10−C11 (113)
F05/v=C09−C10 (114)
F04/v=C08−C09 (115)
F03/v=C07−C08+C12 (116)
F02/v=C06−C07+C11−C12 (117)
F01/v=C05−C06+C10−C11 (118)

The calculator 904 calculates the foreground components based on the equations supplied from the equation generator 903 where the pixel values of the foreground component image are set. For example, when the equations (111) to (118) are supplied from the equation generator 903, the pixel values C05 to C12 are substituted in the equations (111) to (118).
The calculator 904 calculates the foreground components based on the equations where the pixel values are set.

The adjusting portion 905 calculates the pixel value of the foreground where motion blur is eliminated by multiplying the foreground component supplied from the calculator 904 by the amount of movement v included in motion vector supplied from the unit of processing determining portion 901. For example, the adjusting portion 905 calculates the pixel values F01 to F08 of the foregrounds where motion blur is eliminated by multiplying each of the foreground components F01/v to F08/v by 5 of the amount of movement v when the foreground components F01/v to F08/v supplied from the calculator 904 are supplied as shown in
The adjusting portion 905 supplies the calculated foreground component image comprising the pixel values of the foreground where motion blur is eliminated to the motion blur adder 906 and the selector 907.
The motion blur adder 906 may adjust the amount of motion blur by, for example, the amount v′ by which motion blur is adjusted which is different from the amount of movement v and which is half of the amount of movement v, or the amount v′ by which motion blur is adjusted having no relation with the amount of movement v. For example, as shown in
The motion blur adder 906 supplies the foreground component image where motion blur is adjusted to the selector 907.
The selector 907 selects one of the foreground component image from which motion blur is eliminated and which is supplied from the adjusting portion 905, and the foreground component image of which motion blur is adjusted and which is supplied from the motion blur adder 906, for example, on the basis of selection signal corresponding to the selection of an user, and then outputs the selected foreground component image.

In step S903, the equation generator 903 generates an equation for calculating the foreground component from the differences between the pixel values of the foreground components based on the selected or generated model.
In step S904, the calculator 904 sets the pixel values of the foreground component image in the generated equation and extracts the foreground component from the differences between the pixel values on the basis of the equation which sets the pixels. In step S905, the calculator 904 determines whether all the foreground components corresponding to the unit of processing are extracted, and if it is determined that all the foreground components corresponding to the unit of processing are not extracted, the procedure returns to step S904 and the processing for extracting the foreground components is repeated.
In step S905, if it is determined that all the foreground components corresponding to unit of processing are extracted, the procedure proceeds to step S906, and the adjusting portion 905 corrects each of the foreground components F01/v to F08/v supplied from the calculator 904 based on the amount v of movement and then calculates the pixel values F01 to F08 from which the motion blur is eliminated.

In step S1813, the separation portion 2002 of the encoding server 17 performs the image separating processing. Further, the image separating processing is similar to the processing explained referring to step S1013 in the flowchart of
In step S1814, the encoding server 17 outputs the foreground component image and the background component image obtained through the processing in step S1813 to the storage server 18 so as to store them. In step S1813, the storage server 18 stores the foreground component image and the background component image transmitted.
In step S1815, the encoding server 17 adds the motion vector and the positional information to the positional information of foreground component image and the positional information of background component image generated through the encoding processing and transmits them to the client computer 27.
In step S1802, the client computer 27 receives and stores the positional information of foreground component image, the positional information of background component image, the motion vector and the positional information transmitted from the encoding server 17.
Further, in a case of separating and encoding the input image, the encoder 2001 may add only data corresponding to the difference to the code (positional information of the image) of the image already encoded to output it when image similar to a pre-encoded image is encoded. For example, in a case of synthesizing the image shown in
Consequently, when the first image and the second image shown in
Further, the mixture ratio, the motion vector and the positional information to be encoded by the encoding server 17 may be the information specified by a user, as shown in
Further, although the image ID has been employed as the information specifying image in the present invention, the image positional information may be employed instead.
Next, referring to a flowchart of
In step S1901, the client computer 27 outputs the information specifying the images A and B, the motion vector, the mixture ratio, the positional information and the information of amount by which motion blur is adjusted to the synthesizing server 19. That is, as the information specifying the images A and B desired by a user to synthesize, the specific image or the image A ID and B ID (may be the aforementioned positional information of encoded images) specifying the images A and B, the motion vector, the mixture ratio, the positional information and the information of amount by which motion blur is adjusted are output to the synthesizing server 19.
In step S1911, the synthesizing server 16 obtains the specified images. That is, the synthesizing server 19 reads out and obtains the very image when the images are transmitted from the client computer 27 and the images corresponding to the image IDs when the image IDs specifying images are transmitted, via the network 1.
In steps S1912 and S1921, the charge processor 19a of the synthesizing server 19 and the account charge server 24 perform the charge processing. Further, the charge processing is similar to that in the separating service in
In step S1913, the synthesizing server 19 performs the processing of synthesizing the images A and B on the basis of the motion vector, the mixture ratio, the positional information and the information of amount by which motion blur is adjusted.
In step S1914, the synthesizing server 19 generates ID for the synthesized image (A+B) obtained through the processing in step S1913 and transmits it to the client computer 27.
In step S1902, the client computer 27 receives and stores the synthesized image (A+B) transmitted from the synthesizing server 19.
Further, the client computer 27 may store the synthesized image (A+B) transmitted from the synthesizing server 19 in its own storage unit or output it to the storage server 18 via the network 1 so as to store it, in accordance with instructions of the user.
As described above, although the synthesizing server 20 is made to be able to synthesize a plurality of images it may generate the encrypted image by adding the motion blur of the synthesized image using the amount by which motion blur is adjusted as a key.
The input information processor 2031 of the motion blur adder for encryption 2021 outputs the input signal to be encrypted to the imaging portion 2032, outputs information of an encrypting key to the motion blur adder 2033 and outputs the image selection information for selecting image (background component image) desired to synthesize by using the signal to be encrypted as the foreground component image to the synthesizing server 20, respectively.
When the signal to be encrypted input from the input information processor 2031 is not image signal, the imaging portion 2032 converts the signal into the image signal to output it to the motion blur adder 2033. That is, since the encrypted signal is supposed to be image signal, the imaging portion 2032 images the signal that is not image signal in order to correspond with such processing.
The motion blur adder 2033 generates the amount by which motion blur is adjusted on the basis of the information such as speed or direction input from the input information processor 2031 and adds the motion blur to the image signal input from the imaging portion 2032 to output it to the synthesizing server 20. The synthesizing server 20 obtains the background component image on the basis of the image selection information input from the input information processor 2031 and synthesizes the image input from the motion blur adder 2033 as the foreground component image with the obtained background component image to generate and display the synthesized image. At this time, the image selection information specifying the background component image may be the background component image itself and may be the positional information of background component image or ID of the background component image.
Next, referring to
The separation server 11 separates the encrypted synthesized image into the foreground component image and the background component image and outputs the foreground component image to which motion blur is added to the input information processor 2051.
When the encrypted foreground component image input from the separation server 11 and the information on speed and direction as a key for decrypting the encrypted foreground component image are input, the input information processor 2051 output them to the motion blur eliminating portion 2052. When the image is displayed in 2-dimensions of x direction and y direction, the speed and the direction of the key are set thereto, respectively.
The motion blur eliminating portion 2052 generates the amount of motion blur on the basis of the information of speed and direction input from the input information processor 2051, performs the motion blur adding processing inverse to the motion blur adding processing performed by the motion blur adder for encryption 2021 on the encrypted foreground component image, and decrypts the encrypted foreground component image to output it to the signal converter 2053. When the encrypted signal to be encrypted is not image signal, the signal converter 2053 coverts the image signal input from the motion blur eliminating portion 2052 into the original signal to output it.
That is, the motion blur adder 2033 (see
Here, principles in which the image signal is encrypted by adding the motion blur will be explained. For example, as shown in
The encryption using the motion blur adjustment employs this nature and is performed by generating motion blur in the image in the 2-dimensional direction, which cannot be generated in the real world. That is, as shown in
In this state, furthermore, if movement (speed) in the horizontal direction increases to add the motion blur, as shown in the center column and lowermost row, the image in which the motion blur area is spread in the horizontal direction is further obtained. If the motion blur is generated in the vertical direction in this image, as shown in the rightmost column and lowermost row, the motion blur area of the black circle shaped subject is spread and as a whole, and the colors become lighter. As a result, since resolution of the subject is decreased, it is possible to encrypt the image itself.
Next, referring to the flowchart of
In step S2001, the input information processor 2031 determines whether the signal to be encrypted is input or not, the processing is repeated until it is input and if it is determined that it is input, the procedure proceeds to step S2002.
In step S2002, the input information processor 2031 outputs the input signal to be encrypted to the imaging portion 2032. In step S2003, the imaging portion 2032 determines whether the input signal to be encrypted is image signal or not. For example, if it is determined that the signal to be encrypted is not image signal, the imaging portion 2032 converts the signal to be encrypted into image signal to output it to the motion blur adder 2033 in step S2004. In step S2003, if it is determined that the information to be encrypted is image signal, the imaging portion 2032 outputs the input signal to be encrypted to the motion blur adder 2033.
In step S2005, the input signal processor 2031 determines whether the speed and direction information as a key is input or not and repeats the processing until it is input, and if the speed and direction as a key is input, the procedure proceeds to step S2006.
In step S2006, the motion blur adder 2033 encrypts the input image signal in the x direction (adds the motion blur).
Here, referring to
Here, as shown in
If movement in the x direction (in here, the right side in the drawing) is added to the subject, the arrangement of the pixel values shifts at a predetermined time interval and as a result, an arrangement shown in
Further, the respective pixel values on the x y plane are obtained by summing the pixel values shown in
Here, a0*=5×a0, b0*=(5/2)×b0, a0*=(5/2)×a1, c0*=(5/3)×c0, b1*=(5/3)×b1, a2*=(5/3)×a2, d0*=(5/4)×d0, c1*=(5/4)×c1, b2*=(5/4)×b2, a3*=(5/4)×a3, e1*=(5/4)×e1, d2*=(5/4)×d2, c3*=(5/4)×c3, b4*=(5/4)×b4, e2*=(5/3)×e2, d3*=(5/3)×d3, c4*=(5/3)×c4, e3*=(5/2)×e3, d4*=(5/2)×d4 and e4*=5×e4. That is, the weight of each pixel adjusts the gain to be the pixel value by 1 pixel. As a result, if the pixels a to e shown in
If the aforementioned processing encrypts all the rows in the y direction comprised of the 5×5 pixels shown in
Here, returning to the flowchart of
In step S2007, the motion blur adder 2033 encrypts the image signal encrypted in the x direction with respect to the y direction.
Here, as shown in
If movement in the y direction is added to the subject, the arrangement of the pixel values shifts at a predetermined time interval and as a result, an arrangement shown in
Here, returning to the flowchart of
In step S2008, the synthesizing server 19 synthesizes the synthesized background component image with the encrypted image (foreground component image). For example, if the background component image (image having pixels of one step in the x direction) comprised of the pixel values B0 to B9 arranged in the y direction in
By performing all these processes in all the y direction, the synthesized image of which the background component image is the encrypted foreground component image shown in
Further, since is the motion blur adding processing in the motion blur eliminating portion for encryption 2041, in the reverse of the processing by the motion blur adder for encryption 2021, explanation of the decrypting processing will be omitted.
Further, in the processing of step S2006, when encryption in the x direction is performed; the gain-up processing is performed and then, encryption in the y direction is performed. Therefore, it is necessary that after decryption in the y direction is performed, the gain is lowered, and then the decryption in the x direction is performed. Further, the order of the encryptions in the x direction and the y direction may be changed. However, since the gain-up processing is performed in the direction where the encryption is formerly performed, it is necessary that the order of decryptions should correspond to the order of encryptions.
Next, referring to the flowchart of
In step S2101, the client computer 27-1 transmits information desired to encrypt (signal to be encrypted), information of speed and direction as the encryption key and image selection information (information selecting the background component image) to the synthesizing server 19.
In step S2111, the motion blur adder for encryption 2021 of the synthesizing server 19 encrypts the information desired to encrypt (signal to be encrypted) on the basis of the encryption key input from the client computer 27-1 and performs the encrypting processing of synthesizing the selected background component image. Further, since the encrypting processing was explained referring to the flowchart of
In step S2112, the synthesizing server 19 transmits a synthesized image encrypted by adding the motion blur to the client computer 27-1.
In step S2102, the client computer 27-1 displays the synthesized image received from the synthesizing server 19 to determine whether the image is desired by the user or not and if it is determined that the image is the desired image, it is notified to the synthesizing server 19 that the image is the desired image in step S2103. In step S2113, the synthesizing server 19 determines whether the image is the desired image or not and for example, in this case, since it is notified to the synthesizing server 19 that the image is the desired image in step S2103, the procedure proceeds to step S2114.
In step S2114, the charge processor 19a of the synthesizing server 19 and the account charge server 24 perform the charge processing. Further, the charge processing is similar to that of the separating service in
In step S2115, the synthesizing server 19 transmits the synthesized image encrypted to the client computer 27-1. In step S2104, the client computer 27-1 receives the encrypted synthesized image and transmits it to the client computer 27-2.
In step S2141, the client computer 27-2 receives the encrypted synthesized image. In step S2142, the client computer 27-2 determines whether the key is input or not and repeats this processing until the encryption key is input. If the information of speed and direction as the encryption key is input in step S2142, the motion blur eliminating portion 2041 performs the motion blur processing on the basis of the speed and the direction input in step 2143. In step S2144, the image in which the motion blur is eliminated is displayed.
If it is determined that the image was not the desired image in step S2102, it is notified to the synthesizing server 19 in step S2015 that the image is not the desired image and the procedure returns to step S2101. Further, since it is determined by this processing that the image is not the desired image, the processing of the synthesizing server 19 returns to step S2111.
That is, by this processing, when the key of speed and direction specified by a user is correctly input to the client computer 27-1, an image that the encrypted image has been correctly decrypted is displayed. Further, through the same system as the aforementioned encrypting service, the decrypting service can be provided.

The motion blur adjusting portion 2101 adjusts the motion blur of the input foreground component image by the specified amount of motion blur (adjusting amount of correction) and outputs it to the synthesizer 2101. The synthesizer 2101 synthesizes the foreground component image in which motion blur is adjusted and the input background component image and output it as the corrected image.
For example, the image shown in

The synthesizer 2102 synthesizes the foreground component image adjusted as shown in
Further, when the background component image is to be changed into other background component image different from that of the input image, the separated background component image is not input to the synthesizer 2102 and the background component image desired to be changed is input to the synthesizer 2102. Further, the correcting server 20 may be constructed by replacing the separation processor 11, the motion blur adjusting portion 2101 and the synthesizer 2102 with the separation server 11, the motion blur adjusting server 16 and the synthesizing server 19 on the network 1.

Further, the client computer 27 may transmit the image to another client computer 27, for example, to present it. Furthermore, another user may purchase the foreground component image, the background component image, the synthesized image, the corrected image or the like each of which is separated by the separation processing service, the synthesizing service or the correcting service.

The retrieving server 23 retrieves the image which has been picked up on the camera terminal unit 1 connected to the network 1 on the basis of the retrieving conditions input from the client computer 27 and output the request image. The retrieving condition is time, season, weather, area, position, subject or the like.
The control unit 2161 of the retrieving server 23 controls the whole operation of the retrieving server 23. In database 2162, position data which is obtained by GPS 76b provided with a camera terminal unit 28 corresponding to the camera ID of each camera terminal unit 28 which the retrieving server 23 recognizes, weather data, subject data or the like 2062b are stored as database. The contents of the database 2162 are obtained and updated from the camera terminal unit 28 via the network 1 by controlling the communication unit 2165 at a predetermined time interval through the control unit 2161.
The storage unit 2163 stores the image obtained from the camera terminal unit 28 on the network 1 from the communication unit 2165 or stores information needed for the processing of various images.
The requested information generator 2164 arranges the retrieving conditions input from the client computer 27 on the network 1, and then generates the condition for retrieving the database 2162. That is, for example, when season is put as the retrieving condition, the season may be specified by the position data of each camera terminal unit 28 and the time information calculated by the time calculator 2166. So, the requested information generator 2164, for example, in the case when ‘spring’, is input as the retrieving condition, generates the position data of the latitude and longitude of the earth in which it is spring at the present time.

In steps S2612 and S2631, the charge processor 23a of the retrieving server 23 and the account charge server 24 perform the charge processing. Further, the charge processing is similar to that in the separating service in
In step S2613, the retrieving server 23 retrieves the image corresponding to the retrieving conditions and calls out the corresponding image in step S2614. In step S2641, the camera terminal unit 28 transmits the image shown to the retrieving server 23.

At this time, in step S2618, it is notified to the retrieving server 23 that it is not the desired image and the process ends.
In this case, the service fee for the retrieving processing is charged, but the service fee for transmitting the retrieved image is not paid.
According to above description, it is possible to improve the speed of image processing by distributing the image processing to a plurality of server on the network and it is also possible to reduce cost for the service by providing only the processing requested by a user be.
Further, following inventions may be considered.
That is, the present invention may relate to a communication apparatus and method and a communication system and more specifically, a communication apparatus and method and a communication system capable of improving the processing speed by distributing the image processing to a plurality of servers on a network to perform it, reducing the cost for the service by making it possible to perform only the processes desired by a user by means of the distributed processing, in regard to the differences between the real world and the signal detected by a sensor, and regard to the called out images and previous image data which are utilized as needed even without storing it in its own communication apparatus.
The techniques of detecting events in the real world with a sensor and processing the sampling data output from the image sensor is widely employed. However, for example, in the image obtained by taking picture of a body moving in front of a predetermined background being stationary with a video camera, when moving speed of the body is relatively fast, the motion blur occurs.
As a technique for encrypting the aforementioned image in which the motion blur is present, a burying, method for not recognizing the encrypted image in a flat portion of the image or a method for burying information using correlation of the image have been suggested.
Further, when a body is moving in front of the stationary background, the motion blur occurs when the image of the moving body is mixed by its own motion and also by the mixture of the background image and the image of moving body. However, conventionally, the processing corresponding to mixture of the background image and the image of moving body was not considered.
Further, in elimination or adjustment of the motion blur in the aforementioned image, after adjusting the shutter, the motion blur may be tolerated to certain extent to use the motion blur for visual effect. However, in general, when the motion blur is significant, Wiener filter is used for eliminating the motion blur.
Also, a conventional user printed out the aforementioned image as needed through selection of the images taken by the user using his own computer, etc.
For this reason, the image obtained by separating, synthesizing or correcting an image on the basis of the mixture of images is not widely used except for on the user's computer.
Further, when an image of body in which the motion blur occurred and other background image are combined to be synthesized, conventional users obtained the desired background image through a number of searches for being input into the user's computer to be displayed.
For this reason, in retrieving images as described above, it poses a problem that until the desired image was put into the user computer, the same processing was repeated.
Also, in the techniques for synthesizing the desired images via the network, these synthesized images have been generated by overlapping and joining a plurality of pre-existing images such as specified images obtained from images stored in the storage server, etc. on the network or images taken with a digital still camera.
By the way, in order to synthesize images by using the aforementioned techniques, it is premised that images which are bases for synthesizing are previously prepared. However, since there are various know-hows the image pickup techniques, it is difficult to obtain or generate images themselves that are satisfactory bases. For this reason, there is a problem that a user cannot easily obtain or generate desired image databases in generating synthesized image.
Further, in consideration of the above problem, if a user could obtain the desired images, the images having large data capacity must be stored in the user computer without being erased because it is not easy to obtain them again. In this case, it is suggested to perform the optimal encoding in accordance with the feature amounts by separating the image data into the feature amounts of the object and the mixture ratio.

As a result, it is possible to encrypt an image by adding motion blur to the image, and also to decrypt the encrypted image by eliminating the motion blur, that is, adding motion blur inverse to the motion blur added in the encryption process.
Further, it is possible to obtain a clear foreground component image having been eliminated with motion blur by adjusting the motion blur contained in the foreground component image, and to generate a synthesized image appearing seemingly natural by combining the motion blur adjusted foreground component image with a background component image. As a result, by adjusting the motion blur in the foreground component image and by synthesizing an image by processing the resulting foreground component with a background component, it is possible to correct images more naturally.
Moreover, since the image obtained by separating, synthesizing or correcting an image on the basis of mixed state of the image, can be purchased or sold via the network 1, the separated, synthesized or corrected image can be effectively utilized by selling the images processed by the users.
Furthermore, it is possible to retrieve the images which are being photographed, or have been photographed and stored by the camera terminal units 28-1 to 28-n by a simple input of the retrieval conditions.
Moreover, by storing images in a predetermined storage server rather than in user's computer, and by reading out and utilizing the images on the basis of positional information of the storage server as needed, pre-existing image data can be called out and utilized as needed without maintaining them in their own communication apparatus, such that images can be efficiently utilized.
According to above descriptions, it is possible to encrypt image by adding motion blur to the image and decrypt the image by eliminating the motion blur. Further, it is also possible to eliminate motion blur to generate a clear image and correct an image more naturally to synthesize an image in which motion blur is adjusted by combining the motion blur adjusted foreground component with a background image. Further, it is possible to effectively utilize via the network images separated, synthesized or corrected on the basis of mixed state of the image. Moreover, it is also possible to retrieve the separated, synthesized or corrected images via the network.
