2. Description Related to the Prior Art
A digital still camera is equipment for acquiring image data to record an image. An image pickup device in the digital still camera, for example, CCD image sensor, CMOS image sensor or the like, outputs an image signal of an analog form, which is converted to digital data and stored in a data storage. A widely used format of image recordable to the data storage is the EXIF file, according to which the image signal is processed by image processing and compressed according to the JPEG format before storing. Also, raw image data of CCD-RAW file is known, which is unprocessed according to the image signal. JP-A 2002-330388 discloses the digital still camera in which the raw image data is recordable by photographing an image.
As the image pickup device can detect only brightness of the color, filters of red, green and blue colors are combined with the image pickup device. Color information of three primary colors of red, green and blue colors is obtained as the image signal. The combination of the color information is referred to as the raw image data. For the purpose of digital image processing, an image processor is incorporated in the digital still camera for subjecting the raw image data to image processing of plural types, for example color conversion, white balance conversion, exposure processing and the like. To use the EXIF format, the raw image data is processed by the image processing to obtain and store the processed image data.
There are parameters predetermined in the image processor incorporated in the digital still camera. Each of condition settings of image processing is defined by a combination of a plurality of the parameters. A problem lies a finished state of a processed image comes to have a narrowly conditioned appearance after the image processing of the image processor, because the finished state depends on the parameters. The finished state cannot be changed very much even when image correction processing is made for image data after the image processing. Some of numerous camera users wishes to finish an image according to his or her preference and differently from the image processing associated with the digital still camera. The use of the raw image data is supported by such users.
JP-A 2002-330388 discloses a printing system for producing a print according to the raw image data. For printing, the raw image data of one image frame is subjected to the image processing with a plurality of the parameters associated with the condition setting. Plural test images are displayed on a display panel in a reduced size with different parameters. Image frames are selected from the test images, to designate preferred ones of the parameters. The parameters are designated for respectively the condition settings, to facilitate acquisition of the finished state of images.
The parameters of the condition settings, for example exposure and white balance, are factors influencing to one another. The finished state of a developed image is determined according to a combination of a plurality of the parameters of the condition settings. However, only each one of the parameters is changed for simulating plural test images in relation to the condition settings. This is likely to cause separation of an obtained result of the finished state and an expected condition of the finished state in designating the parameters, as the finished state is difficult to estimate.

The above objects and advantages of the present invention will become more apparent from the following detailed description when read in connection with the accompanying drawings, in which:
In
A parameter index image print, or sample or test image sheet 16 with a test image group is produced by the order processing apparatus 10 when an order for printing is placed with inputs of raw image data. The parameter index image sheet 16 will be supplied to the customer 12. A purpose of the parameter index image sheet 16 is for the customer 12 easily to determine parameters of the digital development to which the raw image data is subjected. Plural test images of a thumbnail shape are arranged in one frame of a test image group in various condition settings of plural parameters. As a print sheet with the test image group, the parameter index image sheet 16 is formed, which is also referred to as a round print. The plural test images are based on only one original image, but are different in the finished state, and are candidate images of which the customer 12 can screen one best condition setting suitable for his or her preference in the finished state. The selected condition setting is designated for a photo finisher to input the designated values of the parameters. One frame with an image of the raw image data is printed on photographic paper at the designated parameter. A main print 17 is obtained and supplied to the customer 12.
The order processing apparatus 10 has a system controller 21, a card reader 22 as interface or image reception device, an image processor 23, a data storage device 24, a communication interface 26, a user interface or console panel 27, an index image forming printer 31, and a recording medium drive 32. The user interface 27 includes a display panel 28 and a keypad 29. The system controller 21 includes a CPU, ROM, RAM and the like, and controls elements in the order processing apparatus 10 in response to input signals from the order processing apparatus 10. The keypad 29 or a keyboard together with a mouse is an input device for entry of command signals to the system controller 21. The display panel 28 displays an operating menu, input images and other indicia or message information. Note that the user interface 27 may be a touch panel type of display panel which includes the display panel 28 and the keypad 29. The card reader 22 accesses the memory card 13 and reads image data of any one of various formats, for example EXIF and CCD-RAW formats.
The image processor 23 creates a test image group according to input raw image data. The image processor 23 includes a format converter 23a, an image processing region 23b for digital image development, and an image forming region 23c. Raw image data are according to a plural number of file formats because of inequality between camera manufacturers in the file format, which is unlike the EXIF format as a publicly single format. The format converter 23a converts the raw image data of any one of the file formats into a predetermined file format, and transmits the converted image data to the image processing region 23b. The use of the format converter 23a is effective in no need in changing the image processing region 23b particularly when the known file formats are changed or when a new file format is added.
The image processing region 23b subjects raw image data of an image frame to digital development according to plural condition settings, and produces sample images or test images for checking a finished state of the development. Condition settings are combinations of conditions, which are white balance information, exposure information, and other information related to image processing. The image processor 23 changes a parameter stepwise for each of the conditions, to subject raw image data to development in plural condition settings. Test images are thus created. Data of the test images are transmitted to the image forming region 23c. The image forming region 23c processes the test image data by resizing, and produces data of test images of a reduced image size. Test images in the reduced size are arranged in one frame, to produce a test image group in an index form.
An example of the data storage device 24 is a hard disk drive, and stores an operating system (OS) and plural programs, and also stores image data acquired by use of the card reader 22. Also, the data storage device 24 has a parameter memory region 34 with a parameter designating memory, and a test image memory region 36. The parameter memory region 34 stores parameter data to which the image processor 23 refers. The test image memory region 36 stores test images before being processed for resizing.
The index image forming printer 31 produces the parameter index image sheet 16 by use of a recording sheet according to image data of the test image group produced by the image processor 23. Any one of known image forming device may be used as the index image forming printer 31, for example an ink jet printer for ejecting ink to print an image on a sheet, a laser printer in which laser light is applied to a photosensitive drum to form an image electrostatically, and toner is transferred to a recording sheet from the photosensitive drum. A size of the parameter index image sheet 16 may be any available size, for example an L size used widely in the field of photograph, or A4 size with a large area.
A photographic printer 37 to produce the main print 17 is connected by the communication interface 26 with the order processing apparatus 10. Image data of image frames to be designated for printing are transmitted by the communication interface 26 to the photographic printer 37. Laser light is applied in the photographic printer 37 to the photographic paper according to the image data. An image is created in a latent image form, and then photographically developed to acquire a photographic print.
Image data is transmitted to the photographic printer 37 in a form processed digitally according to the condition setting designated by the customer 12. In the known techniques, most of the available printers are not adapted to image files of the RAW format. It has been slightly difficult to process an order for printing according to image files of the RAW format. In the present invention, the order processing apparatus 10 is operable for digital development, and transmits image data to the photographic printer 37. This makes it possible to utilize the photographic printer 37 of general use without further modification.
The image data for transmission to the photographic printer 37 is sample image data or test image data produced in the course of producing the index test image group and stored in the test image memory region 36. The test image data in the test image memory region 36 is after the digital development but is unprocessed in relation to processing of resizing. The use of the test image data eliminates necessity of the digital development, so that the total time for producing the main print 17 can be shortened. Also, it is possible to preserve the test image data for a predetermined period, so the test image data can be reused if an order for reprinting is placed. This is effective in raising the speed of operation in reprinting.
The recording medium drive 32 writes image data to a CD (compact disk) or other recording medium. The photo shop 11 commercially writes image data to a recording medium as well as it supplies prints. The recording medium drive 32 is used in the photo shop 11, to produce a photo CD storing various data which a customer wishes to preserve in an edited form.
In
A step between values of the exposure parameter is ½ EV in both of the positive and negative directions and with reference to a value of an original state. Types of the light source type information include a light source used originally at the time of photographing, and also incandescent light, fluorescent light, daylight, light in a cloudy weather, and light in shade. Positions in the arrangement of test images are virtually stepwise and in the manner of color temperature values different from one another. Information of the condition setting or image processing conditions is indicated near to the test images 41 alphanumerically, for example, +½ EV, −1 EV, INCANDESCENT, and FLUORESCENT.
Parameters of the two conditions are arranged two-dimensionally. The test images 41 are arranged vertically and horizontally on the table of the changeable values of parameters, so as to list the estimated finished states of the image. This makes it possible to check finished images in a reliable manner as compared with the known technique in which a single parameter is changed for listing. Very slight difference will occur between the estimated finished state and the actually finished state as a result.
For a preferred finished state, the customer 12 selects a preferred one of the sample images or test images 41 within the parameter index image sheet 16, and notifies an operator of the selected one of preference. The display panel 28 of the user interface 27 displays an image equal to the test image group on the parameter index image sheet 16. The operator views a test image selected by the customer 12 on the display panel 28, and designates the same, to input the condition setting to the order processing apparatus 10 with the parameters of preference.
In the present embodiment, a step of values of the exposure parameter is ½ EV. However, a step of values of the exposure parameter may be ⅓ EV or the like. Also, the number of the types according to the light source type information may be more than or less than five (5). For example, flash light as a type of the light source type information may be added. A step between values of a parameter, the number of types of type information, and the like, can be predetermined, but also can be changed according to a setting input by the user interface 27.
The operation of the above construction is described by referring to
The parameter index image sheet 16 is supplied to the customer 12. The customer 12 observes the parameter index image sheet 16, and if he or she finds one of the sample images or test images 41 acceptable for finishing, selects the same to designate the condition setting. If he or she does not find any one of the test images 41 acceptable for finishing, the parameter index image sheet 16 of a second time is produced by varying a set of parameters, and is supplied to the customer 12. The production of the parameter index image sheet 16 is repeated until at least one of the test images 41 is found acceptable. When the condition setting is designated, image data after the digital development according to the determined set of parameters are transmitted to the photographic printer 37, where the main print 17 is produced and supplied to the customer 12.
In
Plural test images 53 are arranged under the test image 52, and are formed according to variations of light source type information. 42 test images 54 are arranged under the test images 53 in a 6×7 matrix form. A vertical axis is taken for a parameter of the exposure. A horizontal axis is taken for white balance information that is a parameter of color temperature. A step between values of the color temperature parameter is 10 mired (mrd) in both of the positive and negative directions.
In
In the hexagonal form in the hue circle, an original point is defined with an original test image of the hatched portion in the setting at the time of photographing. Parameters of adjusting the chromaticity or color balance are arranged for yellow in the upward direction, for blue in the downward direction as a complimentary color of the yellow. The more distant a point is from the original point, the higher the density of the yellow or blue is. The green color is disposed diagonally from the magenta color as a complementary color. The red color is disposed diagonally from the cyan color as a complementary color. The parameters are changed stepwise according to the distance from the original point.
Condition settings, image processing conditions, the values and step of parameters, parameter types and the like can be modified. Also, arrangement of sample images or test images can be changed as desired. Furthermore, two or more test image sheets different from one another in the form may be supplied to a customer, who can designate by use of those test image sheets containing more information for consideration.
In the above embodiments, the order processing apparatus 10 is installed in a shop, store or other space where a user can directly operate the order processing apparatus 10. However, an order processing apparatus of the invention may be an order processing server 71 of
To this end, there is a commercial web site accessible through the Internet 72 for processing orders. The customer operates the personal computer 73 to access the web site to place an order by transmission. There are an image processor and a data storage device in the order processing server 71 in manner similar to the order processing apparatus 10. When the order processing server 71 receives transmission of a set of raw image data uploaded by the personal computer 73 of the customer, the order is received. For processing, a sample image group or test image group is produced according to the raw image data. Then data of the test image group is transmitted to the personal computer 73 by communication of the Internet 72. The customer views the test image group on the display at the personal computer 73, and designates a condition setting by selecting one test image. The data of the condition setting is transmitted to the order processing server 71 to complete processing of an order for printing. After this, image data processed according to the condition setting is transmitted to a photographic printer to produce the main print 17. The main print 17 can be forwarded to or supplied to the customer.
In the above embodiment, the order processing apparatus 10 is for image forming of the test image group. However, an apparatus of the invention may be an image forming apparatus specialized for image forming of the test image group without order processing of an order for printing. Also, a component for the image forming according to the invention may be an electrophotographic device as well as a printer. Also, image forming of the invention may be according to a computer program in which data of a test image group is output but not subjected to printing. Order processing of an order for printing in the invention may be according to a computer program.
Although the present invention has been fully described by way of the preferred embodiments thereof with reference to the accompanying drawings, various changes and modifications will be apparent to those having skill in this field. Therefore, unless otherwise these changes and modifications depart from the scope of the present invention, they should be construed as included therein.
