Description

  The present invention relates to an imaging apparatus and a program.

A compound-eye imaging device is known as an imaging device that captures a right image and a left image for stereoscopic display (see, for example, Patent Document 1). The imaging device can obtain a right image and a left image by imaging a subject using a plurality of imaging systems provided at different positions.
Japanese Patent Application Laid-Open No. 2008-312058

  A subject at infinity is imaged at substantially the same position in the right image and the left image regardless of the baseline length of the right imaging system and the left imaging system. When such a right image and a left image are displayed on the display device, it is viewed as if an infinite subject exists at the position of the display surface of the display device, and all other subjects are present in front of the display surface. It will be viewed.

  In general, if the difference between the position of the display surface in the depth direction and the position where the subject is viewed is large, the burden on the viewer increases. For this reason, if all the subjects are viewed on the front side of the display surface, the burden on the viewer when viewing the subject on the near side increases.

  On the other hand, it is conceivable that the right image and the left image are slid and displayed in the horizontal direction so that a subject at a predetermined reference distance is viewed at the position on the display surface. Thereby, a subject on the back side of the subject is viewed on the back side of the display surface, and a subject on the near side of the subject is viewed on the near side of the display surface.

  However, when the right image and the left image are slid in the horizontal direction so that the subject at the predetermined reference distance is viewed at the position on the display surface, the subject on the very back side (for example, an infinite subject) The viewing position may be too far from the display surface, increasing the burden on the viewer. In particular, if the parallax between the left and right images of the subject on the back side exceeds the eye width, the viewer's eyes will diverge and the burden becomes very large.

  In order to solve the above-described problem, in the first aspect of the present invention, an imaging device that captures a left-eye image and a right-eye image, the left-eye capturing a left-eye image and a right-eye image. When the imaging system for the right eye and the imaging system for the right eye, and the image for the left eye and the image for the right eye are displayed on the display device, the shift amount of the display position of the infinity image in the image for the left eye and the image for the right eye is And an image output unit that outputs an image for the left eye and an image for the right eye so as to have a value greater than 0 and less than or equal to a predetermined eye width.

  According to a second aspect of the present invention, there is provided a program for causing a computer to function as an image output unit in the imaging apparatus of the first aspect.

  It should be noted that the above summary of the invention does not enumerate all the necessary features of the present invention. In addition, a sub-combination of these feature groups can also be an invention.

2 shows a configuration example of functional blocks of the imaging apparatus 100. An example of the positional relationship between the subject 102, the subject 104, and the subject 106 captured by the left-eye imaging system 10 and the right-eye imaging system 20 is shown. The example which displayed the image for left eyes and the image for right eyes which were imaged on the display surface 110 without shifting is shown. An example of image processing in the image processing unit 34 is shown. The example which displayed on the display surface 110 the image for right eyes and the image for left eyes which performed the image process shown in FIG. It is a figure explaining a parallax angle. Another configuration example of the imaging apparatus 100 is shown. 2 shows an exemplary hardware configuration of a computer 1600 according to the present embodiment.

  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 shows a configuration example of functional blocks of the imaging apparatus 100. The imaging device 100 captures a left-eye image and a right-eye image simultaneously. The imaging apparatus 100 includes a left-eye imaging system 10, a right-eye imaging system 20, and an image output unit 30.

  The left-eye imaging system 10 and the right-eye imaging system 20 are provided at positions separated from each other by a predetermined baseline length in the horizontal direction. The left-eye imaging system 10 and the right-eye imaging system 20 simultaneously capture the left-eye image and the right-eye image in synchronization with the operation of the common shutter mechanism.

  The left-eye imaging system 10 and the right-eye imaging system 20 have the same characteristics. The left-eye imaging system 10 and the right-eye imaging system 20 have substantially the same conditions other than the imaging position, such as the same angle of view, the same zoom amount, the same aperture, and the like. Take an image. The imaging directions of the left-eye imaging system 10 and the right-eye imaging system 20 may be substantially parallel. The left-eye imaging system 10 and the right-eye imaging system 20 acquire digital data of the captured image.

  The left-eye imaging system 10 and the right-eye imaging system 20 may detect an image incident on the optical system as needed. The left-eye imaging system 10 and the right-eye imaging system 20 may record data of an image incident on the optical system at the timing when the shutter is pressed in the memory 32. The imaging apparatus 100 may further include a finder screen that displays image data detected by the left-eye imaging system 10 and the right-eye imaging system 20 as needed. The finder screen is, for example, a liquid crystal display.

  The image output unit 30 outputs digital data of the left-eye image and the right-eye image captured by the left-eye imaging system 10 and the right-eye imaging system 20 to a display device external to the imaging device 100. The imaging device 100 may be connected to a display device via the HDMI terminal 36 or the like. The image output unit 30 includes a memory 32, an image processing unit 34, and an HDMI terminal 36.

  The memory 32 stores digital data of a left-eye image and a right-eye image captured by the left-eye imaging system 10 and the right-eye imaging system 20. The image processing unit 34 performs predetermined image processing on the left eye image and the right eye image stored in the memory 32. When the image for the left eye and the image for the right eye are displayed on the display device, the image processing unit 34 has a displacement amount of the display position of the infinity image in the image for the left eye and the image for the right eye larger than 0 and The image for the left eye and the image for the right eye are subjected to image processing so that the constant value D is equal to or smaller than a predetermined eye width. As the predetermined eye width, a value input in advance by a user or the like may be used. The value may be set within a predetermined range such as 65 mm or less.

  Specifically, the image processing unit 34 shifts the relative position in the horizontal direction of the entire left-eye image and the entire right-eye image displayed on the display device, so that the position in the depth direction where each subject is viewed is viewed. Move. However, if the left and right images are shifted indefinitely, for example, the vergence angle of the viewer with respect to an infinitely distant image (or a subject that is the farthest among the subjects included in the image) is parallel (spreading state). It may become close. The image processing unit 34 may calculate a depth map indicating the position in the depth direction of each subject in the left and right images, and the subject at the farthest distance may be an infinite image. The image processing unit 34 may detect the position of the corresponding subject in the left and right images, and calculate the depth map based on the amount of displacement of each subject between the left and right images.

  For this reason, the image processing unit 34 controls the shift amount in the horizontal direction of the image for the left eye and the image for the right eye. More specifically, the image processing unit 34 displays a display position of an infinitely distant image (or a subject farthest among the subjects included in the image) when the left and right images are displayed on an external display device. The horizontal shift amount of the left and right images is controlled so that the shift amount is a constant value D that is greater than 0 and equal to or less than a predetermined eye width.

  Note that the shift amount of the display position of the infinity image when the left-eye image and the right-eye image are shifted by a predetermined pixel varies depending on the pixel pitch of the display device. The image processing unit 34 acquires display information indicating the pixel pitch of the display device via the HDMI terminal 36. The image processing unit 34 may acquire display information including the screen size and the number of pixels in the horizontal direction of the display device.

  Based on the display information, the image processing unit 34 calculates the number of pixels to be displayed by shifting the left-eye image and the right-eye image on the display device. The image processing unit 34 performs image processing for shifting the image for the left eye and the image for the right eye according to the calculated number of pixels, and then trims the image for the left eye and the image for the right eye based on the display information. Good. After shifting the left eye image and the right eye image according to the number of pixels, the image processing unit 34 may cut out only the overlapping portion from each of the left and right images. Further, an image having the same size as the original image may be generated by enlarging each cut-out image.

  The image output unit 30 outputs the image for the left eye and the image for the right eye subjected to the image processing by the image processing unit 34 to the display device. As described above, the image processing unit 34 stores, in the memory 32, the left-eye image and the right-eye image in which the left-eye image and the right-eye image should be displayed with the shift amounts shifted from each other. Remember. The image output unit 30 outputs the left eye image and the right eye image stored in the memory 32.

  Further, the image output unit 30 may output information indicating the shift amount to be displayed by shifting the left-eye image and the right-eye image to the left-eye image and the right-eye image. In this case, the image processing unit 34 calculates information indicating the shift amount based on the left-eye image and the right-eye image. Then, the image processing unit 34 stores information indicating the shift amount in the memory 32 in association with the left-eye image and the right-eye image.

  FIG. 2 shows an example of the positional relationship between the subject 102, the subject 104, and the subject 106 captured by the left-eye imaging system 10 and the right-eye imaging system 20. A subject 102 indicates a subject at infinity (or a subject farthest from the imaging system within the imaging range). A subject 106 indicates a subject closest to the imaging system within the imaging range. A subject 104 indicates a subject at a distance between the subject 102 and the subject 106. The imaging range 12 indicates the imaging range of the right-eye imaging system 20, and the imaging range 14 indicates the imaging range of the left-eye imaging system 10.

  Each subject is imaged with parallax in the right-eye imaging system 20 and the left-eye imaging system 10 according to the distance from the imaging system. However, at infinity, the shift of the imaging range with respect to the size of the imaging range of the right-eye imaging system 20 and the left-eye imaging system 10 is relatively small. Therefore, the position of the subject 102 in the right eye image and the position in the left eye image are substantially the same.

  FIG. 3 shows an example in which the captured left-eye image and right-eye image are displayed on the display surface 110 without shifting from the captured image. The viewer's right eye 112 and left eye 114 are also shown. In this example, on the display surface 110, the subject 102 of the right-eye image and the left-eye image is displayed at substantially the same position. Therefore, the subject 102 is viewed by the viewer so as to be present at the position of the display surface 110.

  Since the subject 104 and the subject 106 are viewed so as to be present on the front side of the subject 102, all the subjects are viewed so that they are present on the front side of the display surface 110. For this reason, for example, when the subject 106 is viewed, the convergence angle of the right eye 112 and the left eye 114 of the viewer may become too large. Therefore, the image processing unit 34 shifts the left-eye image and the right-eye image in the horizontal direction so that the subject 102 is viewed from the back side of the display surface 110. At this time, the image processing unit 34 performs image processing on the image for the left eye and the image for the right eye so that the shift amount of the display position of the subject 102 on the display surface 110 becomes a constant value D equal to or smaller than a predetermined eye width. .

  FIG. 4 shows an example of image processing in the image processing unit 34. As described above, in the left and right images before image processing (the left side in FIG. 4), the image elements corresponding to the subject 102 are arranged at the same position. The image elements corresponding to other subjects have parallaxes D4 and D6 corresponding to the distance to the imaging system at the time of imaging. When the left and right images are displayed on the display surface, as shown in FIG. 3, all the subjects are viewed so as to exist on the near side of the display surface.

  The image processing unit 34 shifts at least one of the right-eye image and the left-eye image in the horizontal direction by the shift amount D2 so that the right-eye image is shifted to the right relative to the left-eye image. Let The image processing unit 34 determines the shift amount D <b> 2 based on a preset constant value D and the pixel pitch of the display surface 110. That is, the image processing unit 34 converts the constant value D indicating the width on the display surface 110 into the shift amount D2 in the left and right images. More specifically, the image processing unit 34 determines the shift amount D2 (the number of pixels in the image data) by dividing the constant value D (unit mm) by the pixel pitch (unit mm).

  The constant value D is, for example, about 40 mm to 50 mm. Thereby, even when a child monitors an image, the left and right eyes can be prevented from being in a divergent state. Further, the constant value D may be about 55 mm to 65 mm. Further, the shift amount of the subject 102 on the display surface may not be the constant value D. The image processing unit 34 may set the shift amount based on the parallax D6 before the image processing of the subject 106 closest to the imaging system among the subjects included in the image.

  For example, the image processing unit 34 relatively shifts the right-eye image and the left-eye image by half of the parallax D6. However, when the shift amount becomes larger than D2 (corresponding to the constant value D), the image processing unit 34 may relatively shift the right eye image and the left eye image by the shift amount D2.

  FIG. 5 shows an example in which the image for the right eye and the image for the left eye subjected to the image processing shown in FIG. By the above-described image processing, the subject 102 is viewed so as to exist on the back side of the display surface 110. In addition, the subject 106 is also viewed so as to exist at a position close to the display surface 110 by performing the image processing.

  By such processing, the position where each subject is viewed can be arranged at a position close to the display surface 110 while maintaining the depth of the stereoscopic image. In addition, since the amount of shift of the subject 102 on the display surface is limited, it is possible to prevent the spread state. For this reason, it is possible to provide a stereoscopic image with a small presence on the viewer and with a sense of reality.

  FIG. 6 is a diagram illustrating the parallax angle. The parallax angle θ is a convergence angle α when viewing one point on the display surface (for example, a point that intersects the center of a straight line connecting both eyes when a straight line perpendicular to the display surface 110 is extended), A difference from the convergence angle β when a stereoscopic image (the subject 102 in FIG. 6) determined by the parallax S between the left and right image elements on the display surface is shown. When the subject 102 is present behind the display surface 110, θ = α−β. When the subject 102 is present on the front side of the display surface 110, θ = β−α.

  As the parallax angle increases, the difference between the position of the display surface 110 where the image is actually displayed and the position where the subject feels to be present increases, increasing the burden on the viewer. For this reason, it is preferable that the constant value D that defines the shift amount of the display position of the subject 102 is set so that the parallax angle θ is equal to or less than a predetermined value. The image processing unit 34 preferably sets the constant value D so that the parallax angle θ with respect to the subject 102 at the farthest distance is 1.5 degrees (more preferably 1 degree) or less.

  The parallax angle θ is determined by the eye width W, the distance L from the viewer to the display surface 110, and the parallax S. The image processing unit 34 may use a preset eye width W. The eye width W may be set in the range of about 40 mm to 65 mm. The image processing unit 34 may determine the distance L based on display information including the screen size in the vertical direction of the display device (display surface 110). The image processing unit 34 may calculate the distance L as three times the screen size in the vertical direction of the display surface 110. In general, the standard viewing distance is three times the screen size in the vertical direction of the display surface 110. The convergence angle α is uniquely determined based on the position on the display surface 110, the eye width W, and the distance L.

  The convergence angle β is determined by the eye width W, the distance L, and the parallax S. Note that it is assumed that the subject 102 exists at a position that intersects the center of a straight line connecting both eyes when a straight line perpendicular to the display surface 110 is extended. Since the values of the eye width W and the distance L are uniquely determined, the convergence angle β is given as a function of the parallax S. Since the parallax angle θ is the difference between the convergence angles α and β, it is given as a function of the parallax S.

  The image processing unit 34 calculates the parallax S at which the parallax angle θ is 1.5 degrees (preferably 1 degree) based on the function of the parallax angle θ. The image processing unit 34 may set a constant value D that defines the amount of deviation at the display position of the subject 102 within a range of the calculated parallax S or less. For example, the image processing unit 34 sets the calculated parallax S as the constant value D.

  By such processing, the parallax angle θ with respect to the subject 102 at the farthest distance can be limited to a certain value or less. For this reason, the burden on the viewer can be reduced. Moreover, it can prevent that both eyes of a viewer will be in a divergent state. However, there is still a case where the convergence angle of the viewer is large for the subject on the near side.

  FIG. 7 shows another configuration example of the imaging apparatus 100. The imaging apparatus 100 of the present example further includes a baseline length control unit 40 in addition to the configuration of the imaging apparatus 100 described with reference to FIG. In the imaging apparatus 100 of the present example, the baseline lengths of the left-eye imaging system 10 and the right-eye imaging system 20 are variable. For example, at least one of the left-eye imaging system 10 and the right-eye imaging system 20 is provided to be slidable in the horizontal direction. The imaging apparatus 100 of this example reduces the convergence angle with respect to the subject on the near side by changing the baseline length.

  The baseline length control unit 40 controls the baseline lengths of the left-eye imaging system 10 and the right-eye imaging system 20. By controlling the baseline length, the shift amount of the position of each subject in the left eye image and the right eye image changes. For example, when the baseline length is shortened, the amount of positional deviation between the left eye image and the right eye image of each subject is reduced. Further, when the base line length is increased, the amount of positional deviation between the left eye image and the right eye image of each subject increases. The vergence angle of the viewer depends on the amount of positional deviation in the left-eye image and the right-eye image of the subject. Therefore, viewing the image by controlling the baseline length and capturing the image A person's convergence angle can be adjusted.

  The baseline length control unit 40 is for the left eye of the subject closest to the left-eye imaging system 10 and the right-eye imaging system 20 among the subjects imaged by the left-eye imaging system 10 and the right-eye imaging system 20. The base line length is controlled so that the positional deviation amount in the image and the right-eye image is equal to or less than a predetermined upper limit value. As a result, for the subject having the largest convergence angle of the viewer, the positional deviation amount in the left-eye image and the right-eye image can be controlled below the upper limit value. Accordingly, the vergence angle of the viewer can be controlled to a certain value or less.

  The vergence angle of the viewer is determined by the eye width of the viewer, the distance to the display surface, and the shift amount of the image elements in the left and right images. The baseline length control unit 40 may calculate the distance to the display surface based on display information including the screen size of the display device. In addition, a predetermined eye width value (for example, a value within a range of about 40 mm to 65 mm) may be input to the baseline length control unit 40. In addition, an upper limit value of the viewer's convergence angle may be input to the baseline length control unit 40.

  The baseline length control unit 40 may calculate the shift amount of the image element in the left and right images corresponding to the set upper limit value of the convergence angle based on the distance to the display surface and the eye width value. The baseline length control unit 40 may use the calculated deviation amount as the upper limit value described above.

  The baseline length control unit 40 detects an image element having a maximum position shift amount in the left and right images captured by the left eye imaging system 10 and the right eye imaging system 20 as needed. The baseline length control unit 40 may detect a combination of corresponding image elements between the left and right images by image matching or the like. The baseline length control unit 40 controls the baseline length so that the positional deviation amount is equal to or less than the upper limit value for the image element having the largest positional deviation amount. That is, when the shift amount of the position of the image element is larger than the upper limit value, the baseline length control unit 40 may shorten the baseline length so that the shift amount is equal to or less than the upper limit value. The left-eye imaging system 10 and the right-eye imaging system 20 cause the memory 32 to store left and right images in a state where the shift amount is equal to or less than the upper limit value. The image processing unit 34 may perform the image processing described with reference to FIGS. 1 to 6 on the left and right images stored in the memory 32.

  1 to 7, the example in which the imaging device 100 is connected to the display device has been described. In another example, the imaging device 100 may be connected to another external device via the HDMI terminal 36. The external device may be a playback device that causes a display device to play back an image. In this case, the imaging device 100 acquires display information of the display device via the playback device.

  FIG. 8 shows an example of a hardware configuration of a computer 1600 according to this embodiment. A computer 1600 according to this embodiment is connected to a CPU peripheral unit having a CPU 1805, a RAM 1820, a graphic controller 1875, and a display device 1880 that are connected to each other by a host controller 1882, and to the host controller 1882 by an input / output controller 1884. Input / output unit having communication interface 1830, hard disk drive 1840, and CD-ROM drive 1860, and legacy input / output unit having ROM 1810, flexible disk drive 1850, and input / output chip 1870 connected to input / output controller 1884 With.

  The host controller 1882 connects the RAM 1820 to the CPU 1805 and the graphic controller 1875 that access the RAM 1820 at a high transfer rate. The CPU 1805 operates based on programs stored in the ROM 1810 and the RAM 1820 and controls each unit. The graphic controller 1875 acquires image data generated by the CPU 1805 or the like on a frame buffer provided in the RAM 1820 and displays the image data on the display device 1880. Instead of this, the graphic controller 1875 may include a frame buffer for storing image data generated by the CPU 1805 or the like.

  The input / output controller 1884 connects the host controller 1882 to the communication interface 1830, the hard disk drive 1840, and the CD-ROM drive 1860, which are relatively high-speed input / output devices. The communication interface 1830 communicates with other devices via a network. The hard disk drive 1840 stores programs and data used by the CPU 1805 in the computer 1600. The CD-ROM drive 1860 reads a program or data from a CD-ROM 1895 and provides it to the hard disk drive 1840 via the RAM 1820.

  The input / output controller 1884 is connected to the ROM 1810, the flexible disk drive 1850, and the relatively low-speed input / output device of the input / output chip 1870. The ROM 1810 stores a boot program that the computer 1600 executes at startup and / or a program that depends on the hardware of the computer 1600. The flexible disk drive 1850 reads a program or data from the flexible disk 1890 and provides it to the hard disk drive 1840 via the RAM 1820. The input / output chip 1870 connects the flexible disk drive 1850 to the input / output controller 1884 and inputs / outputs various input / output devices via, for example, a parallel port, a serial port, a keyboard port, a mouse port, and the like. Connect to controller 1884.

  A program provided to the hard disk drive 1840 via the RAM 1820 is stored in a recording medium such as the flexible disk 1890, the CD-ROM 1895, or an IC card and provided by the user. The program is read from the recording medium, installed in the hard disk drive 1840 in the computer 1600 via the RAM 1820, and executed by the CPU 1805.

  A program installed in the computer 1600 and causing the computer 1600 to function as the image output unit 30 includes a memory module and an image processing module. These programs or modules work on the CPU 1805 or the like to cause the computer 1600 to function as the memory 32 and the image processing unit 34, respectively.

  Information processing described in these programs functions as the memory 32 and the image processing unit 34 which are specific means in which the software and the various hardware resources described above cooperate with each other by being read by the computer 1600. And the specific image output part 30 according to the intended purpose is constructed | assembled by implement | achieving the calculation or processing of the information according to the intended purpose of the computer 1600 in this embodiment by these specific means.

  As an example, when communication is performed between the computer 1600 and an external device or the like, the CPU 1805 executes the communication program loaded on the RAM 1820, and based on the processing content described in the communication program, the communication interface A communication process is instructed to 1830. Under the control of the CPU 1805, the communication interface 1830 reads transmission data stored in a transmission buffer area or the like provided on a storage device such as the RAM 1820, the hard disk drive 1840, the flexible disk 1890, or the CD-ROM 1895, and sends it to the network. The reception data transmitted or received from the network is written into a reception buffer area or the like provided on the storage device. As described above, the communication interface 1830 may transfer transmission / reception data to / from the storage device by a DMA (direct memory access) method. Instead, the CPU 1805 stores the transfer source storage device or the communication interface 1830. The transmission / reception data may be transferred by reading the data from the host computer and writing the data to the transfer destination communication interface 1830 or the storage device.

  The CPU 1805 is all or necessary from among files or databases stored in an external storage device such as the hard disk drive 1840, CD-ROM drive 1860 (CD-ROM 1895), flexible disk drive 1850 (flexible disk 1890), etc. This portion is read into the RAM 1820 by DMA transfer or the like, and various processes are performed on the data on the RAM 1820. Then, the CPU 1805 writes the processed data back to the external storage device by DMA transfer or the like. In such processing, since the RAM 1820 can be regarded as temporarily holding the contents of the external storage device, in this embodiment, the RAM 1820 and the external storage device are collectively referred to as a memory, a storage unit, or a storage device. Various types of information such as various programs, data, tables, and databases in the present embodiment are stored on such a storage device and are subjected to information processing. Note that the CPU 1805 can hold part of the RAM 1820 in the cache memory and perform reading and writing on the cache memory. Even in such a form, the cache memory bears a part of the function of the RAM 1820. Therefore, in the present embodiment, the cache memory is also included in the RAM 1820, the memory, and / or the storage device unless otherwise indicated. To do.

  In addition, the CPU 1805 includes various operations, information processing, condition determination, information retrieval / replacement, and the like described in the present embodiment, which are designated by the program instruction sequence for the data read from the RAM 1820. Is written back to the RAM 1820. For example, when performing the condition determination, the CPU 1805 determines whether the various variables shown in the present embodiment satisfy the conditions such as large, small, above, below, equal, etc., compared to other variables or constants. When the condition is satisfied (or not satisfied), the program branches to a different instruction sequence or calls a subroutine.

  Further, the CPU 1805 can search for information stored in a file or a database in the storage device. For example, in the case where a plurality of entries in which the attribute value of the second attribute is associated with the attribute value of the first attribute are stored in the storage device, the CPU 1805 stores the plurality of entries stored in the storage device.
