[Patent Document 1] Japanese Patent Application Publication No. 2013-59026
However, in Patent Document 1, the object is to acquire a three-dimensional image perceived by a person, and no mention is made of three-dimensional image acquisition that considers entertainment. The purpose of the present invention is to provide a camera system that acquires entertaining three-dimensional images and to provide a controller of the camera system.
In the present invention relates to the camera system, there are two cameras, each camera has a zoom lens, and the focal length of the zoom lens of the two cameras (f1, f2) is interlocked with the distance Dc [m] between the two camera units.
A first aspect of the present invention relates to a camera system.
This system is a camera system having two camera units 21A and 21B. Each of two camera units 21A and 21B has each an optical system included the zoom lens 22A, 22B. The camera system has means for varying the camera distance Dc between the two camera units, the focal lengths (f1, f2) of the zoom lenses of the two camera units, and has control means for controlling the optical systems of the two camera units to be moved so as to be interlocked with the camera distance Dc between the two camera units.
Since the zoom lens focal length (f1, f2) changes in conjunction with the camera distance Dc, this system can change the camera angle of view (lens magnification) and the parallax image interval continuously and smoothly.
A preferred embodiment of this camera system is that the two camera units 21A and 21B have the same characteristic zoom lenses 22A and 22B, and have the same sensors 23A, 23B with the same sensor size, the number of sensor pixels. Then, the camera system controls the optical system of the camera unit, and the control means controls the focal lengths (f1, f2: the same value f [mm]) of the two zoom lenses to maintain the relationship below, with respect to the distance Dc between the two camera units.
f[mm]=a*Dc[m]+b[mm] (a, b: constant) Formula (I)
(In the formula (I), f [mm] is 6 or more and 1200 or less, a is 10 or more and 200 or less, B is 0 or more and 600 or less.)
Because this camera system has the camera units 21A and 21B with the same characteristic zoom lens 22A, 22B, and the sensors 23A and 23B having the same sensor size, and the same number of sensor pixels, if we watch each of the obtained two images by each eye of the left and right, there is an advantage that natural stereoscopic images.
f[mm]=a*Dc[m]+b[mm] (a, b: constant) Formula (I)
(In the formula (I), f [mm] is 6 or more and 1200 or less, a is 10 or more and 200 or less, B is 0 or more and 600 or less.)
Also, because this camera system controls the optical system of the camera unit so as to maintain the above relationship, there are advantages that it keeps down feeling discomfort of viewing while experiencing the difference with the usual feeling when viewing it, and that it realizes the optical configurations acceptable to perceive for stereoscopic viewing.
In a preferred embodiment of this camera system, it has the means for varying the distance Dc [m] between the two camera units respectively in conjunction with the height h [m] which two camera units 21A and 21B positioned. Interlocking the camera height h and the camera unit distance Dc [m] and the focal lengths of the zoom lens, the optical system of the camera system can acquire images of the left and right eyes as if the human body is large (or small).
In a preferred embodiment of this camera system, the means of varying the distance Dc [m] maintains the relationship of the formula (II) with respect to the height h (=h1=h2) [m] which the two camera units 21A and 21B are positioned.
Dc[m]=c*h[m]+d[m] (c, d: constant) Formula (II)
(In the formula (II), Dc [m] is 0 or more and 100 or less, c is 0.01 or more and 5 or less And d is 0 or more and 100 or less.)
By controlling in this manner, there are advantages that it is possible to obtain an optical configuration which can be sensuously tolerated by a person in stereoscopic viewing, at the same time that it suppresses discomfort of feeling as much as possible, and that it can be realized to acquire 2 images as if a person reproduces the image when viewing as it gradually becomes bigger, while experiencing the difference from the usual sense.
In a preferred embodiment of this camera system, the height control means maintains the relationship of the formula (II), the formula (III), with respect to the height h (=h1=h2) [m] of the two camera units 21 and the distance Dc [m] between two camera units.
Dc[m]=c*h[m]+d[m] (c, d: constant) Formula (II)
f[mm]=i*h[m]+j[mm] (i, j: constant) Formula (III)
(i=a*c, j=a*d+b)
By controlling in this manner, there are advantages that it is possible to obtain an optical configuration which can be sensuously tolerated by a person in stereoscopic viewing, at the same time that it suppresses discomfort of feeling as much as possible, and that it can be realized to acquire 2 images as if a person reproduces the image when viewing as it gradually becomes bigger, while experiencing the difference from the usual sense.
A preferred embodiment of this camera system further comprises a first controller 33 settable constant a and b. Since it has such a controller, it is possible for the user to set up the difference with the usual sense when viewing according to his/her preference. There is an advantage that a stereoscopic image peculiar to the user can be created.
A preferred embodiment of the camera system comprises a second controller 70 capable of setting one or both of them ((1) the constant c and d, (2) the constant i and j). By such a controller, there is an advantage that a stereoscopic image peculiar to the user can be created, so that the user sets the difference from the usual feeling at the time of viewing according to his/her preference.
A preferred embodiment of this camera system comprises a third controller (33, 70). Since it has such a controller, it is possible for the user to set up the difference with the usual sense when viewing according to his/her preference. There is an advantage that a stereoscopic image peculiar to the user can be created.
A preferred embodiment of this camera system further comprises one flying object 40, and the two camera units 21A and 21B are attached to one flying object 40. Since it has such a configuration, there is an advantage that the positional freedom of the image subject and the camera system is high in order to eliminate the physical restrictions on height and position control.
A preferred embodiment of this camera system further comprises two flying objects 90A, 90B, and the two camera units 21A, 21B each have two flying objects 90A, 90B, respectively. Since it has such a configuration, there is an advantage that the positional freedom of the image subject and the camera system is high in order to eliminate the physical restrictions on height and position control.
According to the present invention, since the zoom lens focal lengths (f1, f2) are set with respect to the camera distance Dc, the camera angle of view (lens magnification) and the interval between the parallax images can be changed continuously. In particular, by interlocking the camera height h, the camera distance Dc [m] between the camera units and the focal length of the zoom lens, the optical system of the camera system is possible to acquire two images of the left and right eyes when the human body becomes bigger (or smaller). Therefore, by observing the resulting image, to experience the 3D image not unnatural can be achieved.
Normally, the human eye has the same focal length for the right eye and the left eye, but in reality the focal length for the right eye and the left eye are a little bit different. Though the focal length is slightly different, we can see two images of both eyes as almost the same, because we can correct well with the brain.
Therefore, it is ideal that the same focal length f interlocks with the interval Dc of the camera unit. However, as long as it is somewhat different focal lengths f1 and f2, it is no problem.
A first aspect of the present invention relates to a camera system.
This system is a camera system having two camera units 21A and 21B. The two camera units 21A and 21B include zoom lenses 22A and 22B. In addition to the zoom lens, this optical system has a known structure possessed by the optical system of the camera can be appropriately adopted. Therefore, the two camera units 21A and 21B are possible to adjust the focal length. Elements for adjusting the focal length are known. For example, the focal length can be adjusted by moving the zoom lens in the optical axis direction. That is, the camera system can move the zoom lens as one element of the optical system as long as it has a means (eg, actuator) that can be used. Receiving a command from the control unit to activate the actuator, the position of the zoom lens is adjusted and the focal length is adjusted.
The camera system has means for varying the distance Dc between the two camera units. When two camera units are connected by an actuator etc., the distance between the two camera units can be controlled by the control unit to activate the actuator so that. On the other hand, when two camera units are mounted on different ones (for example, the first camera unit is mounted on the first drone and the second camera unit is mounted on the second drone), using GPS (for example), the two position of the object to be mounted may be controlled while measuring the position and distance of the camera units. Also, one of the two camera units has an observation part for observing the other position, while measuring the distance Dc between the two camera units, using the observation information of the two camera units. So, by changing the position of the camera unit, the distance Dc between the two camera units may be varied.
The control means controls the zoom lens focal length (f1, f2) of each of the two camera units in conjunction with the distance Dc between the two camera units. When the control means is connected to the two camera units by wire, the user inputs information on the distance Dc between the two camera units in the system. Then, on the basis of the information on the input Dc, the control means adjusts the distance Dc between camera units. On the other hand, the control means controls the zooming corresponding to the distance Dc. Since the focal length is read out from the storage unit or calculated by the calculation unit, the optical system of the camera unit is controlled based on the focal length (f1, f2) obtained. Specifically, the two camera units are designed to be able to adjust the distance between the lens and the image sensor, and the distance between the lens and the image sensor may be adjusted according to the control signal from the control unit. If the two camera units are mounted on the flying object, the control means transmits a radio signal to the flying object, the receiving unit of the flight object receives the control signal, and according to the received control signal, the control means adjusts the optical system, and adjusts the focal length. In this case, for example, the actuator can adjust the distance between the lens and the image sensor.
Since the zoom lens focal lengths (f1, f2) are set with respect to the camera unit distance Dc in this system and the magnification is changed, the camera angle (lens magnification) and the spacing of the parallax image can be changed continuous and smoothly.
A preferred embodiment of this camera system is that the two camera units 21A have the same characteristic zoom lenses 22A and 22B and the same sensors 23A, 23B with the same sensor size, the number of sensor pixels. When two camera units have the same characteristic of the lens and the image sensor, it is easy to adjust the focal length. In this embodiment, the camera system controls the optical system of the camera unit, and the control means controls the focal lengths (f1, f2: the same value f [mm]) of the two zoom lenses to maintain the relationship below, with respect to the distance Dc between the two camera units.
f[mm]=a*Dc[m]+b[mm] (a, b: constant) Formula (I)
(In the formula (I), f [mm] is 6 or more and 1200 or less, a is 10 or more and 200 or less, b is 0 or more and 600 or less.)
f [mm] may be 10 or more and 1000 or less, may be 15 or more and 500 or less, or 200 r more and 300 or less.
The constant a may be 15 or more and 150 or less, may be 20 or more and 100 or less, or may be 25 or more and 70 or less.
The constant b may be 0 or more and 400 or less, may be 1 or more and 300 or less, or 2 or more and 200 or more Or less.
In this camera system, the camera units 21A and 21B have the same characteristic zoom lens 22A, 22B, and the sensors 23A and 23B having the same sensor size and the same number of sensor pixels Therefore, when viewing the two images obtained with the left and right eyes it is possible to see with almost the same image quality. So, there is an advantage that natural stereoscopic images without feeling of incompatibility can be appreciated.
f[mm]=a*Dc[m]+b[mm] (a, b: constant) Formula (I)
(In the formula (I), f [mm] is 6 or more and 1200 or less, a is 10 or more and 200 or less, b is 0 or more and 600 or less.)
Also, because this camera system controls the optical system of the camera unit so as to maintain the above relationship, there are advantages that it keeps down feeling discomfort of viewing while experiencing the difference with the usual feeling when viewing it, and that it realizes the optical configurations acceptable to perceive for stereoscopic viewing.
In the case of having an actuator as one element of the optical system, the camera system can move the zoom lens by the actuator driven in response to a command from the control unit, and the focal length can be adjusted by moving the lens.
In a preferred embodiment of this camera system, two camera units 21A and 21B are positioned the means for varying the distance Dc [m] between the two camera units in conjunction with the height h [m] respectively. In the camera system of this embodiment, for example, since the two camera units are equipped with GPS, GPS can grasp the height of the camera unit. When two each camera unit is mounted on two each flying object, each flying object may have a GPS. In this case, the height of one of the flying objects is defined as the height h [m] alternatively, the average of the heights of the two flying objects may be h [m]. Also, two flight objects may be controlled to be about the same. Since the camera height h and camera unit distance Dc [m] and the focal length of the zoom lens are interlocked, the optical system of the camera system can obtain the two images of the left and right eyes when the human body gets bigger (or smaller). The methods for controlling the height of the aircraft are known, and the camera system may control the flying object to be a predetermined height by steering the flying object while measuring the height of the flying object.
In a preferred embodiment of this camera system, the means of varying the distance Dc [m] maintains the relationship of the formula (II) with respect to the height h (=h1=h2) [m] which the two camera units 21A and 21B are positioned.
Dc[m]=c*h[m]+d[m] (c, d: constant) Formula (II)
(In the formula (II), Dc [m] is 0 or more and 100 or less, c is 0.01 or more and 5 or less and d is 0 or more and 100 or less.)
When two camera units are mounted on separate items, Dc [m] is 0.1 or more and 100 or less, and may be 0.2 or more and 50 or less, or may be 0.2 or more and 20 or less. In the case where two camera units are mounted on a single items, since increasing Dc [m] is difficult, Dc [m] may be, for example, 0 or more and 1 or less, or 0 or more It may be 0.5 or less, or may be 0 or more and 0.3 or less.
The constant c may be 0.05 or more and 4 or less, or may be 0.1 or more and 3 or less. The constant d may be 0 to 80, 1 to 70, or 2 to 50.
By controlling in this manner, there are advantages that it is possible to obtain an optical configuration which can be sensuously tolerated by a person in stereoscopic viewing, at the same time that it suppresses discomfort of feeling as much as possible, and that it can be realized to acquire 2 images as if a person reproduces the image when viewing as it gradually becomes bigger, while experiencing the difference from the usual sense.
In a preferred embodiment of this camera system, the height control means maintains the relationship of the formula (II), the formula (III), with respect to the height h (=h1=h2) [m] of the two camera units 21 and the distance Dc [m] between two camera units.
Dc[m]=c*h[m]+d[m] (c, d: constant) Formula (II)
f[mm]=i*h[m]+j[mm] (i, j: constant) Formula (III)
(i=a*c, j=a*d+b)
By controlling in this manner, there are advantages that it is possible to obtain an optical configuration which can be sensuously tolerated by a person in stereoscopic viewing, at the same time that it suppresses discomfort of feeling as much as possible, and that it can be realized to acquire 2 images as if a person reproduces the image when viewing as it gradually becomes bigger, while experiencing the difference from the usual sense.
A preferred embodiment of this camera system further comprises a first controller 33 settable constant a and b. Since it has such a controller, it is possible for the user to set up the difference with the usual sense when viewing according to his/her preference. There is an advantage that a stereoscopic image peculiar to the user can be created. This controller is made possible to give and receive the information from the storage, if the constants a and b is input in the controller, the control unit stores the values of the constants a and b in a predetermined area of the storage unit. In addition, the control unit reads out the values of the input constants a and b, and the other values which is necessary for calculation, and the calculation unit is caused to perform predetermined calculation. In this way, the focal length f, the value of the distance Dc can be obtained, and the value can be used to control the camera system.
A preferred embodiment of the camera system comprises a second controller 70 capable of setting one or both of them ((1) the constant c and d, (2) the constant i and j). For example, if this controller is able to set the constants c and d (or i and j) can be set, the user may adjust only the constant c. Further, the controller 70 is the same as the first controller 33 described above one device may be used. The first controller 33 may have the function of the second controller. Since it has such a controller, it is possible for the user to set up the difference with the usual sense when viewing according to his/her preference.

Since it has such a controller, it is possible for the user to set up the difference with the usual sense when viewing according to his/her preference. There is an advantage that a stereoscopic image peculiar to the user can be created. The third controller may be the same device as the first controller or the second controller. When the third controller (33, 70) sets the distance Dc, the value of the distance Dc is input to the camera system. Then, the control unit controls the actuator based on the input distance Dc or adjusts the position of the camera unit while measuring the distance by confirming the position of the camera unit by using GPS and adjusting the position of the camera unit. Thus the control unit controls so as to approach the value of the input distance Dc.
A preferred embodiment of this camera system further comprises one flying object 40, and the two camera units 21A and 21B are attached to one flying object 40. Since it has such a configuration, there is an advantage that the positional freedom of the image subject and the camera system is high in order to eliminate the physical restrictions on height and position control. Examples of the flying body 40 are an airplane, a helicopter, a model plane, a model helicopter, and a drone. These include, for example, a radio reception unit receiving a radio signal from the controller, and it is possible to change the position of the body according to the radio signal received by the radio reception unit.

First, with reference to
f[mm]=a*Dc[m]+b[mm] (a, b: constant) (1)
When acquiring a 3D image, in order to obtain the images of the left and right eyes equivalent to the human, basically it is common to use the same optical properties, sensor characteristics. By doing so, the drive control of two optical is possible to control the control of the system in approximately the same parameters, the camera system structure becomes simpler.
The zoom lens 22 is the power zoom which can vary the zoom position by a motor, and it is possible to control to a predetermined focal length by the command transferred from the camera zoom drive control 24 for each of the two cameras.
Here, when the minimum setting value Xmin=0.1 m of the camera distance, the minimum setting value of the camera zoom (focal length) f [mm] is 24 mm, and the maximum camera setting value Xmax=1 m, the camera zoom focal point of maximum set value of the distance) f=96 mm is set. In other words, in
On the other hand, in the independent drive, the respective drive controllers 33A and 33B are independently driven, and the movable range can be set by setting the maximum and minimum set values of the mode conditions in
The constants a and b in the equation (1) are a=80 and b=16 respectively, respectively, the interlocking drive is the mode to maintain the relationship below.

4) Transfer the image to be displayed as Live View among the obtained images to the display 32 via the memory 38, so that the image can be confirmed by the monitor unit 31. When recording button is pressed, the camera image processing 37 generates the recording images and stores the image data in the recording medium 39 through the memory 38.
5) Slide with either slider of drive controller 33A or 33B. For example, gradually slide the camera distance 0.1 m→1 m. In doing so, from the interface 34 of monitor unit 31, through the camera controller 35, the camera zoom drive control 24 changes the focal length f. In this case the drive controller 33 changes the focal length f with the relationship of equation (2) set according to the drive controller 33 position at flow 1).
6) At the same time, from the interface 34 of the monitor unit 31, through the camera distance drive control 36, the slide drive control 25 changes the distance Dc [m] which is set according to the drive controller 33 position at flow 1).
As mentioned in 1) to 6), by either slider (the drive controller 33A or 33B) sliding, the other slider automatically slide, as a result the camera unit distance Dc and the camera focal length f are changed in conjunction with each other.
(In this case, presented as still images)
By watching the recorded image with a not-shown three-dimensional television, 3D movie system or 3D goggle, it is possible to view the stereoscopic image.
Here, we consider the optical system of the human eye.
Assuming that constituted by a digital camera as the same configuration of
Based on the above, it can be said that it is possible to realize the configuration shown in
If we think of it as a giant's feelings here, it seems that if you are a small person in the body you can see the nearby objects finely and the far objects look small, but if we are a giant, we must want to see the far object finely corresponding to the size of the body. So I assume an optical system that we want to request when we became huge people.
With such a configuration, the magnification will be high, so that visibility of far objects will also increase for the far object, so that a sense of perspective appropriate for the giant should be obtained. In other words, giant eye, rather than the optical system as it is proportionally expanded human, giant was seen in conjunction with the difference, it should become more visibility is good configuration to increase to some extent magnification. It was however, if we raise the magnification too much, we will lose the wide angle that the human eye has, so we should be able to choose the balance setting taking into consideration the balance between magnification and wide angle.
Based on the above-described viewpoints, this embodiment proposes a configuration that embodies a camera system that can simulate the giant's eye in a pseudo manner.
In the second embodiment, the difference from the first embodiment is that the slide structure 26 is integrally formed with the drone 40. In the second embodiment, the camera distance drive control 36, which is a feature of the present invention, is configured to control in conjunction with the drone controller 60.
By taking the above configuration, it is possible to acquire images for obtaining three-dimensional images in various conditions including aerial space, though what was assumed terrestrial fixed in the first embodiment.
The constants a and b of the equation of the distance Dc [m] of the camera unit and the focal length f [mm] are a=80 and b=16 respectively as in the first embodiment,

From equations (3) and (4)
f[mm]=0.4*h[m]+16 (5)
As described above, both Dc [m] and f [mm] are set in conjunction with h [m].
At a height of 20 m or less and a height of 200 m or more, the camera zoom and the camera distance are fixed to the minimum and the maximum, respectively. In this case, it is possible to automatically set the optical configuration of the two lens camera units in conjunction with the drone operation, and it is possible to acquire a pseudo image in which the human is enlarged or reduced.

7) The information of the detected camera height h [m] is transmitted to the interface 34 of the monitor unit 31. And the camera distance drive control 36 maintains the camera distance Dc [m] of the interlocking relation of the equation (4).
8) Simultaneously, from the interface 34 of the monitor unit 31, through the camera controller 35, the camera zoom lens drive control 24 changes the focal length f interlocked with the camera distance Dc [m] (camera height h [m]), on the based on the equation (3), (5).
By performing the above sequence, the camera height h [m], the camera unit distance Dc [m], and the focal length f [mm] can be operated in conjunction with each other.
In the third embodiment, the difference between this embodiment 2, camera unit 21 instead of the slide mechanism portion 26 is a point which is constituted by drone 90 each independently. Though the drone 90A, 90B are necessary to be controlled the various physical quantities, including the distance Dc [m] camera units each attitude control, angle control, they are automatically controlled by the drone controller 60. The camera distance drive control 36 which is a feature of the present invention, is configured to control in cooperation with the drone controller 60.
By adopting the above configuration, it is possible to acquire images, and it becomes possible to acquire a three-dimensional image under various conditions including aerial space as in the second embodiment.
The configuration view of the drone controller 60 and the monitor unit 31 and the setting screen for the height h [m] interlocking mode have the same configuration as in the second embodiment.
The constants a and b of the equation of the distance Dc [m] of the camera unit and the focal length f [mm] are a=100 and b=14,

From equations (6) and (7)
f[mm]=0.5*h[m]+14 (8)
At a height of 2 m or less and a height of 200 m or more, the camera zoom and the camera distance are fixed to minimum and maximum, respectively. In this case, in conjunction with the drone manipulating optical structure of 2-eye camera unit automatically it can be set, the giant is the human eye, obtaining a pseudo image such as that reduction becomes possible.

4) Transfer the image to be displayed as Live View among the obtained images to the display 32 via the memory 38, so that the image can be confirmed by the monitor unit 31. When recording button is pressed, the camera image processing 37 generates the recording images and stores the image data in the recording medium 39 through the memory 38.
5) The drone camera height h [m] is arbitrarily changed by the operator's pilot.
6) The height h of two eye camera system which is a height from the respective ground hA, hB are detected by the camera height detection system that 27 by ultrasonic distance sensor (not shown) which are mounted on the drone 90A, 90B.
7) Information on the detected camera height h [m] is transmitted to the interface 34 of the monitor unit 31.
8) On the other hand, the gyro sensor (not shown) attached the drone 90A, 90B detects the angular displacement of the camera axis deviation angle θx, θy, θz [deg] in
9) Further, the camera distance Dc [m] between the drones is also detected by the ultrasonic distance sensor (not shown).
10) The drone distance attitude control 45 maintains the camera distance Dc of the interlocking relationship of the formula (7) through the interface 34, the camera distance drive control 36 with respect with information on the detected camera height h [m].
11) Simultaneously, from the interface 34 of the monitor unit 31, through the camera controller 35, the camera zoom lens drive control 24 changes the focal length f interlocked with the camera distance Dc [m] (camera height h [m]), on the based on the equation (6), (8).
By performing the above sequence, the camera height h [m], the camera unit distance Dc [m], and the focal length f [mm] can be operated in conjunction with each other.
In embodiment 2 and 3, the ensuring accuracy of the detection of camera height h [m] and the camera unit distance Dc[m] has shown an example of detecting the ultrasonic sensor. The ensuring accuracy of the detection may be a laser distance meter, also future GPS which the detection accuracy can be improved. The distance Dc [m] between the cameras units may be detected only by the GPS detection system used for angle detection. In addition, a detection system not shown here may be adopted for height detection and camera interval detection.
By using the camera system embodiment as described above, we can obtain an image that can virtually experience the Ultraman eyes as shown in
In the second and third embodiments, the configuration in which the height is interlocked by the drone configuration has been described, but the same function can be realized by providing the height drive mechanism in the first embodiment.
Further, in the present embodiment, description has been made assuming a process of becoming a giant, but it is possible to provide a different pseudo-sense even if the interlocking properties of the zoom lens and the camera interval are set to different patterns. Such an example is also included in the present invention.
