  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In each embodiment, means and members having the same function are denoted by the same reference numerals, and description thereof is omitted.

(First embodiment)
[Outline of image display system]
FIG. 1 is a diagram illustrating an outline of an image display system according to an embodiment of the present invention, (a) is a schematic diagram of the image display system, and (b) is a diagram illustrating an element image group captured by a photographing camera. FIG. 4C is a diagram illustrating an element image transmitted from the photographing camera to the image display device.

As shown in FIG. 1A, the image display system 1 includes a photographing camera 2 and an image display device (client PC) 3.
The photographing camera (single camera) 2 is a digital camera that has a lens array 21 on the front surface and photographs a group of element images of the subject H (in FIG. 1, only some element lenses 21a are shown). Here, the lens array 21 is configured such that a total of twelve element lenses 21a, 3 vertical × 4 horizontal, are arranged on the same plane. The photographing camera 2 is connected to the image display device 3 via a network 5 such as a wired LAN (Local Area Network), a wireless LAN, or an intranet, and transmits a part of the element image to the image display device 3. To do.
The image display device 3 generates a display image from the element image transmitted from the photographing camera 2 and displays it.

  First, the image display device 3 transmits transmission element image information indicating the position and number of element images transmitted from the photographing camera 2 to the image display device 3 via the network 5 before photographing the subject H. Send to. Here, the transmission element image information indicates, for example, two element images located in the center of the element image group.

  Next, when the transmission element image information is received, the photographing camera 2 stores the transmission element image information and images the subject H. As described above, since the photographing camera 2 includes the twelve element lenses 21a, the element image group including the twelve element images is photographed as illustrated in FIG. Here, since the two element images located in the center of the element image group are set as the transmission element image information, the photographing camera 2 is configured as shown in FIG. 1C, as shown in FIG. Of the group of element images, only the two element images located in the center are transmitted to the image display device 3 (thick frame portion in FIG. 1B).

  That is, since the photographic camera 2 transmits the element image of FIG. 1C to the image display device 3, the image display system 1 is more effective than the case of transmitting the element image group of FIG. The amount of transmission can be reduced.

[Camera configuration]
FIG. 2 is a block diagram showing a configuration of the photographing camera of FIG. As shown in FIG. 2, the photographing camera 2 includes a storage unit 22, a photographing element 23, a correcting unit 24, a decomposing unit 25, a selecting unit 26, an encoding unit (transmitting unit) 27, and a transmission element image. Information receiving means 28. In FIG. 2, the lens array 21 is not shown.

The transmission element image information receiving unit 28 receives transmission element image information from the image display device 3 via the network 5 before photographing with the photographing camera 2.
The storage means 22 stores the transmission element image information received by the transmission element image information reception means 28, and includes a RAM (Random Access Memory), a HDD (Hard Disk Drive), and the like. In addition, the storage unit 22 stores parameters including the number of element lenses 21a (vertical and horizontal numbers), the size of the element lens 21a, and the installation conditions of the photographing camera 2 such as the distance from the photographing camera 2 to the subject H. May be.

  The transmission element image information indicates the position and number of element images transmitted from the photographing camera 2 to the image display device 3. In order for the image display device 3 to display a multi-viewpoint image, the transmission element image information sets the number of element images at arbitrary positions to two or more. For example, when the image display device 3 displays a free viewpoint planar image, the transmission element image information sets the number of element images for generating a free viewpoint planar image to 4 (for 4 viewpoints). The transmission element image information may set a plurality of adjacent element images, or may set a plurality of element images separated from each other.

  Further, for example, when the image display device 3 displays an image for left and right eyes (a stereoscopic image using binocular parallax), the transmission element image information indicates the number of element images for generating a left eye image as 2 ( (2 viewpoints), the number of element images for generating the right eye image is set to 2 (2 viewpoints). The transmission element image information may be set as a plurality of element images at adjacent positions as element images for generating a left-eye image and an element image for generating a right-eye image. A plurality of element images may be set. A plurality of pieces of transmission element image information may be set so as to include the same element image as an element image for generating an image for the left eye and an element image for generating an image for the right eye. That is, the position of the element image is set in the transmission element image information so that the element image for generating the left-eye image and the element image for generating the right-eye image overlap.

  The transmission element image information is used as a reference for the element image at the upper left of the element image group, and the position of each element image to be transmitted to the image display device 3 is expressed by a coordinate system called element image (x, y). Good (x is the horizontal position of the element image, y is the vertical position of the element image). For example, in the element image group in FIG. 1B, the position of the upper left element image is the element image (1, 1), and the position of the lower right element image is the element image (4, 3). Become.

  When performing multicast transmission described later, the storage unit 22 may store multicast information having an IP (Internet Protocol) address of the image display device 3 that performs transmission by multicast. In this case, the multicast information is set in advance by the operator.

  The imaging element 23 is for imaging the subject H, and is composed of, for example, a CCD (Charge Coupled Device) and a CMOS (Complementary Metal Oxide Semiconductor). Here, since the photographing element 23 photographs the subject H via the lens array 21, it can photograph an elemental image group of the subject H composed of elemental images corresponding to each element lens 21a of the lens array 21.

  The correction unit 24 performs at least one of geometric correction and color correction on the elemental image group captured by the imaging element 23. For example, when the lens array 21 is not perpendicular to the imaging element 23 or the optical axis of the lens array 21 does not match, the correction unit 24 performs geometric correction by enlarging, reducing, rotating, and translating the element image group. Examples of this geometric correction include affine transformation, pseudo-affine transformation, projective transformation, and transformation using a transformation map. In addition, for example, when there is a lens distortion such as a mold distortion in the element image group, the correction unit 24 performs geometric correction such as conversion using a higher-order term and conversion using a conversion map.

  Further, the correction unit 24 may perform color correction such as density, contrast, saturation, and hue of the element image group in accordance with the photographing state of the element image group. For example, when the contrast of the element image group is low, the correction unit 24 corrects the density and contrast of the element image group. For example, when the subject H is photographed with red eyes of a person or an animal (red eye), the correction unit 24 performs color correction for correcting the red eye portion to black. Note that the correction unit 24 may perform only one of geometric correction and color correction, or may perform both geometric correction and color correction.

  The disassembling means 25 decomposes the element image group after being imaged by the image sensor 23 and corrected by the correcting means 24 into element images. Here, the decomposing unit 25 may refer to the parameters stored in the storage unit 22 to obtain the number of element lenses 21a and equally divide (decompose) the element image group by the number of element lenses 21a. Further, the disassembling unit 25 may dispose the element image group at a predetermined position by installing the photographing camera 2 so that each element image is captured at a predetermined position in the element image group. In this case, the position where the element image group is decomposed can be obtained from the installation conditions of the photographing camera 2.

  Further, when the element image group includes a marker serving as a reference for decomposing each element image, the decomposition unit 25 may decompose the element image group using this marker as a reference. FIG. 3 is a diagram for explaining the details of the disassembling means of FIG. 1, (a) is a diagram showing an example of a lens array, and (b) is a diagram for explaining an element image group photographed through this lens array. FIG. As shown in FIG. 3A, a frame 21 b that is substantially perpendicular to the imaging element 23 is provided between the element lenses 21 a of the lens array 21. When the subject H is photographed through the lens array 21 in FIG. 3A, the photographing element 23 has a frame 21b in a lattice shape between the element lenses 21a as shown in FIG. 3B. Take a group of element images. In this case, the decomposing means 25 performs a process of extracting the color of the frame 21b (for example, black region extraction), extracts the frame 21b copied in the element image group as a marker, and uses the frame 21b (marker) as a reference. The element image group is decomposed into.

  For example, in the lens array 21 of FIG. 3A, for example, the element lenses 21a are bonded by UV curable adhesives in a total of 12 vertical 3 × 4 horizontal 12 pieces. Each element lens 21a has, for example, a frame 21b, a size of 1 mm in length × 1 mm in width, and the material is transparent plastic or quartz glass. The size, material, and number of element lenses 21a are not limited to this. For example, the lens array 21 may be one in which spherical lenses are formed at predetermined intervals as element lenses 21a on both surfaces of a single transparent plastic plate or quartz glass plate.

  The selection unit 26 in FIG. 2 selects an element image to be transmitted to the image display device 3 from among the element images decomposed by the decomposition unit 25 based on the transmission element image information stored in the storage unit 22. Here, when two or more element images are set in the transmission element image information, the selection unit 26 selects all the set element images.

  The encoding unit 27 transmits the element image selected by the selection unit 26 to the image display device 3. For example, the encoding unit 27 encodes the element image as a moving image by the MPEG method, and transmits the element image as a still image by the JPEG method and transmits the encoded image to the image display device 3. The encoding unit 27 corresponds to the transmission unit described in the claims.

  In addition, the encoding unit 27 collects a plurality of element images, encodes them by, for example, the MVC method, and transmits them to the image display device 3. Conventionally, in the MVC method, when a multi-viewpoint image is captured with a multi-camera, encoding is performed using the fact that the images of each camera are similar when the shooting angle of each camera approximates the subject. It was thought to be intended for multi-cameras. Here, the present inventors pay attention to the fact that the element images included in the element image group photographed by the photographing camera 2 are similar, and the MVC method considered to be a multi-camera is a single camera. This was applied to the photographing camera 2.

  In FIG. 2, the photographing camera 2 is described as the element image group after the correction unit 24 corrects the element image group by the decomposition unit 25, but is not limited thereto. For example, in the photographing camera 2, after the decomposition unit 25 decomposes the element image group into element images, the correction unit 24 refers to the transmission element image information and corrects only the element image transmitted to the image display device 3. (Not shown). As a result, the photographing camera 2 does not need to correct all the element images, and the amount of calculation of the element image correction processing can be suppressed.

[Configuration of image display device]
FIG. 4 is a block diagram showing a configuration of the image display apparatus of FIG. As shown in FIG. 4, the image display device 3 includes a transmission element image information transmission unit 31, a decoding unit 32, an image generation unit 33, a display unit 34, and a storage unit 35.

  The transmission element image information transmission unit 31 transmits the transmission element image information to the photographing camera 2 via the network 5 before photographing with the photographing camera 2. Here, the transmission element image information transmission unit 31 may transmit the transmission element image information to the photographing camera 2 before the photographing camera 2 photographs the subject H, and the transmission timing and the number of transmissions are not particularly limited. . For example, the transmission element image information transmission unit 31 transmits the transmission element image information to the photographing camera 2 every time the transmission element image information is changed. Further, for example, the transmission element image information transmission unit 31 transmits the transmission element image information to the photographing camera 2 in accordance with an instruction from the operator.

  Further, for example, the transmission element image information transmission unit 31 transmits the transmission element image information to the photographing camera 2 at a constant time interval (for example, every hour). Further, the transmission element image information transmitting means 31 determines whether or not the transmission of the transmission element image information is successful. When it is determined that the transmission has failed, the transmission element image information is retransmitted to the photographing camera 2. Also good. Thus, it is possible to prevent the photographing camera 2 from storing the transmission element image information. The transmission element image information is set in advance by an operator, for example.

  The decoding unit 32 receives the element image selected by the photographing camera 2 based on the position and number of element images set in the transmission element image information from the photographing camera 2. In addition, when the element image is encoded by MPEG or JPEG, the decoding unit 32 decodes the received element image.

  The image generation unit 33 generates a display image from the element image received by the decoding unit 32. For example, when an element image for the right eye (for example, two viewpoints) and an element image for the left eye (for example, two viewpoints) are received from the photographing camera 2, the image generation unit 33 performs the right eye for two viewpoints. The depth information at the right eye position is calculated using the element image, and a display image for the right eye is generated from the depth information. Then, the image generation unit 33 generates the left-eye display image using the left-eye element images for two viewpoints, similarly to the right-eye display image. Further, when the display unit 34 displays a stereoscopic image, the image generation unit 33 calculates the three-dimensional coordinates (vertical, horizontal, and depth) of the subject H from the element image received by the decoding unit 32, and uses this result. Thus, a stereoscopic image (display image) may be generated.

The display unit 34 displays the display image generated by the image generation unit 33, and is, for example, a cathode ray tube display or a liquid crystal display. The display unit 34 may display not only the display image generated by the image generation unit 33 but also the display image stored by the storage unit 35.
The storage unit 35 stores the display image generated by the image generation unit 33 and the element image received by the decoding unit 32, and can be configured by an HDD or the like, similar to the storage unit 22 of FIG. .

[Camera operation]
FIG. 5 is a flowchart showing the operation of the photographing camera of FIG. 2 (see FIG. 2 as appropriate). In FIG. 5, it is assumed that the transmission element image information is transmitted from the image display device 3 and stored in the storage unit 22 in advance.

  First, the photographing camera 2 photographs an element image group of the subject H by the photographing element 23 (step S11). The photographing camera 2 performs at least one of geometric correction and color correction on the element image group photographed by the photographing element 23 by the correcting unit 24. Here, the photographing camera 2 performs color correction such as density, contrast, saturation, hue, and the like of the element image group according to the photographing state of the element image group by the correcting unit 24 (step S12).

  Subsequent to the processing in step S12, the photographing camera 2 uses the disassembling unit 25 to decompose the element image group after the photographing element 23 has photographed and corrected by the correcting unit 24 into each element image. Here, the photographing camera 2 may divide the element image group by the number of the element lenses 21a by the disassembling unit 25 (decompose), may decompose the element image group at a predetermined position, or The element image group may be disassembled with reference to the frame 21b (marker) copied to the element image group (step S13).

  Following the processing of step S13, the photographing camera 2 transmits the element image decomposed by the decomposing unit 25 to the image display device 3 by the selecting unit 26 based on the transmission element image information stored in the storage unit 22. An element image is selected (step S14). The photographing camera 2 transmits the element image selected by the selection unit 26 to the image display device 3 by the encoding unit 27. Here, the photographing camera 2 may transmit the element image after encoding the element image by the MPEG method or the JPEG method by the encoding unit 27. Furthermore, the photographing camera 2 may encode the plurality of element images together by the MVC method by the encoding unit 27 and transmit the encoded image to the image display device 3 (step S15).

With the above processing, the photographing camera 2 transmits only the element images required by the image display device 3 to the image display device 3, so that the amount of image transmission can be suppressed.
In FIG. 5, the photographing camera 2 has been described as performing the process of step S13 following the process of step S12, but the present invention is not limited to this. For example, the photographing camera 2 may operate by exchanging the process of step S13 in FIG. 5 and the process of step S12 (not shown).

[Operation of image display device]
FIG. 6 is a flowchart showing the operation of the image display apparatus of FIG. 4 (see FIG. 4 as appropriate).
The image display device 3 transmits the transmission element image information described above to the photographing camera 2 via the network 5 by the transmission element image information transmission unit 31 (step S21).

  Following the processing of step S21, the image display device 3 receives, from the photographing camera 2, the element image selected by the photographing camera 2 according to the transmission element image information by the decoding unit 32. Here, when the received element image is encoded by the MPEG method or the JPEG method by the decoding means 32, the image display device 3 decodes the element image by the MPEG method or the JPEG method. Further, when the received element image is encoded by the MVC method by the decoding unit 32, the image display device 3 decodes the element image by the MVC method. And the image display apparatus 3 produces | generates a display image from the element image which the decoding means 32 received by the image generation means 33 (step S22).

Following the processing in step S22, the image display device 3 displays the display image generated by the image generation unit 33 by the display unit 34 (step S23).
With the above processing, only the element images required by the image display device 3 are received from the photographing camera 2 and the display images are displayed, so that the amount of image transmission can be suppressed.

(Second Embodiment)
