Description

  The present invention relates to an image display apparatus and method, and more particularly to an image display apparatus and method that can make pixel defects inconspicuous.

Recently, television receivers whose display units are composed of liquid crystals, plasma displays, and the like are becoming widespread. The display unit of the television receiver is desired to have a higher density so that a more detailed image can be displayed. The display portion can be increased in density by being manufactured using a semiconductor process. Various proposals have been made to increase the density (for example, Patent Document 1).
JP-A-5-5096

  However, when the density is increased, the pixels become smaller and the image can be displayed in detail. On the other hand, the pixels are likely to be defective during manufacturing. As a result, there is a problem that the display state of the image deteriorates.

  The present invention has been made in view of such a situation, and makes it possible to make pixel defects inconspicuous.

According to an aspect of the present invention, a display unit in which a plurality of display areas each displaying an image are arranged close to each other along one plane, and a single display area having a plurality of pixels from each of the pixels. one lens for emitting substantially parallel light to light is arranged close correspondingly, and a lens array section where light Ru emitted image from a plurality of pixels of the corresponding display area by the lens, the lens, Image light from a plurality of pixels in the corresponding display area is imaged on the user's retina and viewed as a single virtual image by the user as substantially parallel light in a direction corresponding to the position in the display area. An image display device that emits light .

In one aspect of the present invention, an image is displayed by each of a plurality of display areas that are arranged close to each other along one surface, and light from each of the pixels is omitted in one display area having a plurality of pixels. A single lens that emits as parallel light is arranged correspondingly in close proximity, and the lens emits image light from a plurality of pixels in the corresponding display region. In addition, the direction of the position corresponding to the position in the display area so that the light of the image from the plurality of pixels in the corresponding display area is formed on the user's retina and visually recognized as one virtual image by the user. Are emitted as substantially parallel light.

  According to one aspect of the present invention, an image can be displayed, and in particular, an image can be displayed without conspicuous pixel defects.

  FIG. 1 shows a configuration example of an image display device as an embodiment of the present invention. The image display device 1 includes a display unit 11, a lens array unit 12, a cover glass 13, a circuit unit 14, and an adjustment unit 15.

  For example, as shown in FIG. 2, a plurality of display elements 31 are arranged in the display unit 11. Each display element 31 includes, for example, a liquid crystal display device, an organic EL (Electroluminescence) display device, an FED (Field Emission Display) display device, or the like. In the example of FIG. 2, a total of 49 display elements 31 of 7 × 7 are arranged in a matrix along one plane. Each display element 31 has a display area 31A, and each display element 31 is configured to display an independent image. That is, each display element 31 is composed of a plurality of pixels, and can display an image that can be recognized by a person. In the example of FIG. 2, the image of the character S is displayed for each.

  The display unit 11 is provided with a lens array unit 12 in close proximity to and substantially parallel to the display unit 11. For example, as shown in FIG. 3, the lens array unit 12 includes a plurality of lenses 41. One lens 41 is disposed adjacent to one display area 31A. Therefore, the lenses 41 are also arranged in a matrix along one plane (a surface parallel to the surface along which the display element 31 is aligned). In the example of FIG. 3, a total of 49 lenses 41 of 7 × 7 are provided.

  The surface on which the display element 31 and the lens 41 are arranged may be a gently curved surface instead of a flat surface. Further, the display elements 31 and the lenses 41 are arranged at a constant pitch interval so that one image can be recognized by a person as a whole (so that an image is not locally lost).

  A cover glass 13 is disposed on the front surface of the lens array unit 12. The display unit 11, the lens array unit 12, and the cover glass 13 are integrated.

  The circuit unit 14 outputs an image signal for displaying the same image (an image having parallax when displaying a stereoscopic image) on each display element 31 of the display unit 11. The adjustment unit 15 adjusts the distance between the display unit 11 and the lens array unit 12 (the display element 31 and the lens 41) based on an instruction from the user.

  The light of the image displayed by each of the display elements 31 is made into substantially parallel light by the lens 41 and is incident on the left eye 21L and the right eye 21R of the user through the cover glass 13.

  FIG. 4 shows a state in which light rays incident at various angles on the eye 21 (when the left eye 21L and the right eye 21R do not need to be individually distinguished are simply referred to as the eye 21) are imaged on the retina. As shown in the figure, an iris 72 is arranged around the pupil 71 of the eyeball 21A. The substantially parallel light emitted from the lens 41 enters the eyeball 21A through the pupil 71 and forms an image at points 61-11 to 61-13 on the retina 60. The image of the light beam 51-11 shown in the center of the figure is formed at a point 61-11. An image of the light beam 51-12 incident on the pupil 71 from the left side in the drawing from the light beam 51-11 is formed at a point 61-12 located on the right side in the drawing from the point 61-11. On the contrary, the image of the light beam 51-13 incident from the right side in the drawing from the light beam 51-11 is formed on the point 61-13 located on the left side in the drawing from the point 61-11.

  FIG. 5 shows the relationship between the light emitted from the display element 31 and the lens 41. As shown in the figure, in the case of this embodiment, the lens 41 is constituted by a substantially spherical lens. The lens 41-1 corresponding to the display element 31-1 and the lens 41-2 corresponding to the display element 31-2 are disposed adjacent to (in contact with). Although illustration is omitted, lenses are also arranged on the left side of the lens 41-1 in the drawing and on the near side and the depth side in the direction perpendicular to the paper surface. Similarly, lenses are arranged on the right side in the drawing of the lens 41-2 and on the near side and the depth side in the direction perpendicular to the paper surface. The display unit 11 has a display surface disposed in the vicinity of a focal point (focal length) that is formed when substantially parallel light rays enter the lenses 41-1 and 41-2. In other words, the image light emitted from the display element 31-1 is emitted as substantially parallel light from the lens 41-1. Similarly, the image light emitted from the display element 31-2 is emitted as substantially parallel light from the lens 41-2.

The light emitted from the point P _L1 slightly on the right side from the substantially center on the display element 31-1 is made into substantially parallel light by the lens 41-1, and forms an image at a point 61-13 on the retina 60, for example. Light emitted from a point P _C1 on the left side of the drawing (approximately the center of the display element 31-1) from _L1 is made into substantially parallel light by the lens 41-1, and forms an image at a point 61-11 on the retina 60. And

Similarly, an image emitted from a point P _L2 (corresponding to the point P _L1 of the display element 31-1) slightly to the right of the center of the display element 31-2 located on the right side in the drawing from the display element 31-1. The light is made into substantially parallel light by the lens 41-2, forms an image at a point 61-13 on the retina 60, and is located at a point P _C2 located on the left side (substantially the center of the display element 31-1) from the point P _L2 . Light emitted from (corresponding to the point P _C1 of the display element 31-1) is made substantially parallel light by the lens 41-2 and forms an image on the point 61-11 on the retina 60.

In this way, the light emitted from the points P _L1 and P _L2 as the corresponding pixels forms an image at the same point on the retina 60, and similarly, the points P _C1 and P P as the corresponding pixels are formed. All the light emitted from _C2 forms an image at the same point on the retina 60.

  The above will be further described with reference to FIG. 6 as follows. That is, as shown in FIG. 6, the display area 31-11A is located on the leftmost side in the figure, the display area 31-12A is located on the right side (substantially in the center), and the display area 31-13A is the display area. It is assumed that it is located further to the right than 31-12A. A real image 91-11 is displayed in the display area 31-11A, a real image 91-12 is displayed in the display area 31-12A, and a real image 91-13 is displayed in the display area 31-13A. These real images 91-11 to 91-13 have substantially no parallax and are substantially the same image. Thereby, a two-dimensional image is visually recognized. When a stereoscopic image is viewed, the image has parallax.

  In FIG. 6 and FIGS. 7 and 8 to be described later, the optical path is actually refracted on each surface of the lens, but is shown in a simplified manner.

  Of the real image 91-11 of the display area 31-11A, the light beam 81-11 emitted from the pixel located on the left side in the drawing is made into substantially parallel light by the lens 41-11 and is connected to the point 61-12 on the retina 60. Image. However, in the real image 91-11, the light ray 82-11 emitted from a pixel located farther to the right in the drawing than the pixel corresponding to the light ray 81-11 is transmitted through the lens 41-11 as compared to the light ray 81-11. It becomes difficult to form an image within the field of view on the retina 60. A light ray 83-11 emitted from a pixel located further to the right than the pixel corresponding to the light ray 82-11 is further connected to the visual field range on the retina 60 via the lens 41-11 as compared with the light ray 82-11. It becomes difficult to image. That is, the light from the pixel located on the left side is dominant in the light imaged at the point 61-12 in the visual field range on the retina 60 in the real image 91-11.

  In the real image 91-12 of the display region 31-12A located almost at the center in the figure, the light beam 81-12 emitted from the pixel located farthest to the left in the figure and the pixel located farthest to the right in the figure. Compared with the emitted light beam 83-12, the light beam 82-12 emitted from the pixel located substantially at the center is dominant in the light imaged at the point 61-11 in the visual field range on the retina 60.

  On the other hand, the light is emitted from the real image 91-13 of the display region 31-13A located on the rightmost side in the drawing, is made into substantially parallel light by the lens 41-13, and reaches a point 61-13 in the visual field range on the retina 60. As a light beam to be imaged, a light beam 83-13 emitted from a pixel located farthest to the right in the figure is dominant, followed by a light ray 82-13 emitted from a pixel located farther to the left. The light beam 81-13 emitted from the pixel located on the leftmost side is most difficult to form an image at the point 61-13 in the field of view on the retina 60.

  In this way, among the pixels of the real image 91-11 displayed by the display region 31-11A, a light beam having a dominant component of the light beam emitted from the pixel located on the left side, the display region 31-12A located in the center Among the pixels of the real image 91-12, the light having the dominant component as the light emitted from the substantially central pixel, and the pixel of the real image 91-13 in the display area 31-13A located on the rightmost side, Light rays having a dominant component of light rays emitted from the pixels are imaged at points 61-12, 61-11, 61-13 in the field of view on the retina 60, respectively.

  The image of the point 61-12 is recognized as a virtual image 92-11 by the light beam 81-11A virtually obtained by tracing the light beam 81-11 from the lens 41-11 in the reverse direction. The image of the point 61-11 is recognized as a virtual image 92-12 by the light ray 82-12A virtually obtained by tracing the light ray 82-12 from the lens 41-12 in the reverse direction. The image of the point 61-13 is recognized as a virtual image 92-13 by a light ray 83-13A virtually obtained by tracing the light ray 83-13 from the lens 41-13 in the reverse direction. In fact, since the same phenomenon occurs for all other pixels, the user can view the entire plurality of real images displayed in the display areas 31A including the real images 91-11 to 91-13 through the eye 21. It is visually recognized as one synthesized virtual image. That is, the virtual image optical system is configured so that light emitted from the display unit 11 forms an image on the retina 60 based on the principle of the light beam reproduction method. Thereby, it is possible to realize a thinner image display device.

  FIG. 7 schematically illustrates the above. That is, as shown in the figure, it is assumed that the same images 111-21 to 111-23 (character S images) are displayed in the display areas 31-21A to 31-23A, respectively. In the display region 31-21A located on the leftmost side in the drawing, the light whose main component is the image of the portion 31-21A1 located on the leftmost side (the left portion of the letter S) is substantially collimated by the lens 41-21. Then, an image is formed at a point 61-12 in the visual field range on the retina 60. On the other hand, in the display region 31-21A, the light of the image of the portion 31-21A2 located substantially in the center and the portion 31-21A3 on the right side thereof (the image of the center portion and the right portion of the character S) is The image is not formed in the field of view on the retina 60 through the lens 41-21, or even if the amount of energy is small.

  Of the pixels in the display region 31-22A located substantially at the center in the drawing, the amount of energy of light that forms an image at the point 61-11 in the visual field range on the retina 60 via the lens 41-22 is located on the leftmost side. Of the portion 31-22A1 and the portion 31-22A3 located on the rightmost side (the left side portion and the right side portion of the character S) have few components, and the image of the portion 31-22A2 located substantially in the center (the character S There are many components in the middle part).

  Among the pixels in the display region 31-23A located on the rightmost side in the figure, the amount of energy of light that forms an image on the point 61-13 within the visual field range on the retina 60 via the lens 41-23 is on the rightmost side. The component of the image of the portion 31-23A3 positioned (the portion on the right side of the letter S) is dominant, and the portion 31-23A2 positioned on the left side of the portion 31-23A3 and the portion 31-23A1 positioned further on the left side of the portion 31-23A3 The components of the image (the center portion and the left portion of the character S) are reduced.

  As described above, in the eye 21, the same images 111-21 to 111-23 displayed in the display areas 31-21A to 31-23A are combined and visually recognized as one image 112 by the user. That is, an image having the left portion of the image 111-21 (character S) as a main component, an image having a central portion of the image 111-22 (character S) as a main component, and an image 111-23 (character S). An image (virtual image) whose main component is the right part is synthesized as one image 112 (character S).

  The above is performed not only in the horizontal direction but also in the vertical direction. This will be described with reference to FIG.

  That is, it is assumed that the display area 31-31A, the display area 31-32A, and the display area 31-33A are located at the top, center, and bottom in the drawing, respectively. Lenses 41-31 to 41-33 are arranged corresponding to the respective display areas 31-31A to 31-33A.

  Of the image 121-31 (character S) displayed in the display area 31-31A, most of the light of the image (the upper part of the character S) of the uppermost portion 31-31A1 passes through the lens 41-31. Then, an image is formed on a point 61-11L (a lower point (not shown) perpendicular to the paper surface of the point 61-11 in FIG. 4) within the visual field range on the retina 60. On the other hand, the light of the image (the central part and the lower part of the character S) of the part 31-31A2 located below the part 31-31A1 and the part 31-31A3 located further below it. Is difficult to image at the point 61-11L within the field of view on the retina 60, or does not image.

  Similarly, of the image 121-32 (character S) displayed in the display area 31-32A positioned substantially at the center, the light of the image of the portion 31-32A (center portion of the character S) positioned approximately at the center is displayed. Most of the images are formed on the point 61-11 in the field of view on the retina 60 through the lens 41-32, but the images of the upper part 31-32A1 and the lower part 31-32A3 are formed. The light of the upper part and the lower part of the letter S is difficult to form an image at the point 61-11 or does not form an image.

  Also in the lowermost display area 31-33A, most of the light of the image (lower part of the letter S) of the lowermost part 31-33A3 in the figure passes through the lens 41-33. Then, an image is formed at a point 61-11U in the field of view on the retina 60 (an upper point (not shown) perpendicular to the paper surface of the point 61-11 in FIG. 4), but a portion 31- located above the point 61- The light of the image of 33A2 (the center part of the letter S) and the light of the image of the part 31-33A1 (the upper part of the letter S) positioned further above it are difficult to form an image at the point 61-11U. Or does not image.

  As described above, the user's eye 21 emits light whose main component is a different part (upper part, central part, or lower part of the character S) of substantially the same image (character S). It is synthesized and recognized as one virtual image 131 (character S). Thereby, even when a predetermined pixel of one display element 31 has a defect and the pixel cannot be displayed, the display of the pixel of the other display element 31 in the vicinity compensates for this, so that the defect of the pixel is made inconspicuous. Can do.

  FIG. 9 illustrates a configuration example of the circuit unit 14 that provides an image signal to the display unit 11. The circuit unit 14 includes an output unit 211 and a drive unit 212. The output unit 211 includes a tuner, a memory, and the like, and outputs an image signal received and demodulated by the tuner or an image signal read from the memory to the drive unit 212. The drive unit 212 outputs the image signal input from the output unit 211 to the display elements 31-1 to 31-n configuring the display unit 11. The display elements 31-1 to 31-n have display areas 31-1A to 31-nA, respectively. In the case of this embodiment, the drive unit 212 supplies the same image signal to each of the display elements 31-1 to 31-n. Accordingly, the display areas 31-1A to 31-nA each display the same image.

  Next, image display processing will be described with reference to the flowchart of FIG.

  In step S11, the output unit 211 outputs an image signal by receiving and demodulating with a tuner, reading from a memory, or the like. In step S12, the drive unit 212 drives each display element. Specifically, the drive unit 212 supplies the image signal input from the output unit 211 to the display elements 31-1 to 31-n. In step S13, the display unit 11 displays an image. That is, the display elements 31-1 to 31-n display images corresponding to the image signals supplied from the drive unit 212 in the corresponding display areas 31-1A to 31-nA, respectively.

  Light mainly composed of different portions of the same image displayed on the display elements 31-1 to 31-n corresponds to the corresponding lenses 41 (display elements 31-1 to 31-n) of the lens array unit 12. The image is formed on the retina 60 of the user's eye 21 through the user's eyes 21, and the user recognizes this as one image (virtual image).

  In the above description, n display elements 31 are provided. However, the number of display elements 31 may be one and the display area may be individually divided. That is, as shown in FIG. 11, one display element 31 can be provided with n display areas 31-1 </ b> A to 31-nA. In this case, the same image is displayed in each of the display areas 31-1A to 31-nA. For this reason, in the example of FIG. 11, a conversion unit 251 is inserted between the output unit 211 and the drive unit 212. The conversion unit 251 converts the image signal that is input from the output unit 211 and displays one image on one screen into an image signal that displays n images on one screen.

  Other configurations are the same as those in FIG.

  Next, image display processing in the case of the configuration of FIG. 11 will be described with reference to the flowchart of FIG.

  In step S31, the output unit 211 outputs an image signal. In step S32, the conversion unit 251 converts the image signal. That is, the conversion unit 251 converts the image signal for one screen input from the output unit 211 into an image signal of an image in which n identical images are displayed on one screen. For example, an image signal of an image in which one character S is displayed on one screen is converted into an image signal of an image in which 7 × 7 S characters are displayed on one screen as shown in FIG. Convert. In step S33, the drive unit 212 drives the display element. That is, the drive unit 212 drives the display element 31 of the display unit 11 based on the image signal supplied from the conversion unit 251. In step S34, the display unit 11 displays an image. In other words, the image of the character S is displayed on each of the n display areas 31-1A to 31-nA constituting one display element 31. As shown in FIG. 2, this display state is substantially the same as when the character S is displayed independently on each of the plurality of display elements 31.

  Accordingly, an image (virtual image) of one character S is synthesized and displayed on the user's eye 21 as in the case of the configuration of FIG.

  It is also possible to cause the tuner to receive an already converted image signal. In this case, the conversion unit 251 can be omitted, and the configuration of the circuit unit 14 is the same as that shown in FIG.

  FIG. 13 and FIG. 14 show the ray bundle when the ray ray is traced from the pupil 71 (not shown) located on the left side in the drawing. The angle shown in these figures means the angle of light emitted from the pupil 71. It can be seen that the incident position of the light bundle with respect to the lens 41 changes according to the angle from the pupil 71.

  Generally, the maximum diameter of the human pupil 71 is said to be about 4 mm. Therefore, the pitch P of the lenses 41 is preferably set so that the difference (P−D) between the effective diameter D of the lenses 41 (see FIGS. 15 and 16 described later) is 4 mm or less. Thereby, it is possible to prevent the image from becoming discontinuous (a part of the image is lost) due to a gap larger than the diameter of the pupil 71 between the lens 41 and another lens 41 adjacent thereto. it can.

  FIGS. 15 and 16 show the detailed configuration of the lens array unit 12. In the example of FIGS. 15 and 16, the lens 41 is disposed on the surface 302 so as to be in close contact with each other, and is coupled by the coupling portion 301. In this embodiment, the thickness of the coupling portion 301 is set to a value smaller than the diameter of the lens 41.

  In this case, black paint or the like is mixed into the synthetic resin constituting the coupling portion 301, or the upper and lower surfaces of the coupling portion 301 are colored black so as not to transmit light. A value smaller than the pitch can be set. In this way, for example, as shown in FIG. 15, an external angle that is an angle greater than or equal to a predetermined value with respect to an arrow 311 in the direction in which the corresponding display element 31 faces (direction perpendicular to the surface 302). It is possible to prevent the light beam 312 from passing through the lens 41. Thereby, it is suppressed that the image from the adjacent display element 31 leaks and becomes interference light.

  FIG. 17 illustrates another configuration example of the coupling unit. In this example, the coupling portion 341 is formed to have substantially the same thickness as the diameter of the lens 41 so that a wall is formed around the lens 41. Even in this case, if the coupling portion 341 is formed of a light-shielding material, it is possible to suppress interference due to light from the adjacent display element 31 as in the case of FIG. Can transmit the light ray 312 within a predetermined value, and can block the light ray whose angle with the arrow 311 is increased.

  In the above, the lens 41 is constituted by one spherical lens. For example, as shown in FIG. 18, a protective layer 362 is disposed behind the lens 361 so that the light emitted from the display unit 11 is emitted. You may comprise so that it may become substantially parallel light. In the embodiment of FIG. 18, the lens 361 has both end faces (end faces in the left-right direction in the figure) within a predetermined range centered on the optical axis formed in a substantially spherical shape. Is formed in a substantially cylindrical shape.

  FIG. 19 shows still another configuration example of the lens 41. In this configuration example, a protective layer 372 is disposed behind the lens 371. The lens 371 has one surface and the other surface that are substantially part of a spherical surface, but has a convex lens shape as a whole.

  By configuring the lens as shown in FIG. 18 or FIG. 19, it becomes possible to correct the aberration of the portion around the lens.

  The distance between the lens and the display unit 11 (display area 31) can be adjusted and set to a predetermined value. This will be described with reference to FIGS. In these configuration examples, a protective layer 382 is provided behind the spherical lens 381.

  FIG. 20 illustrates a configuration of the image display device 401 in which the distance between the display unit 11 and the lens 381 is adjusted so that light emitted from the display unit 11 is emitted from the lens 381 as parallel light. The display surface (display region 31) of the display unit 11 is disposed on the focal length of the lens 381. Therefore, the light of the image displayed on the display unit 11 is emitted as parallel light from the lens 381.

  On the other hand, in the image display device 402 shown in FIG. 21, the position of the display surface of the display unit 11 is closer to the lens 381 than the position of the focal length of the lens 381 than in the case of the image display device 401 of FIG. It is set to be a little closer. Therefore, the light of the image displayed on the display unit 11 is slightly diverged, but is emitted from the lens 381 as substantially parallel light. 22 is set so that the display surface of the display unit 11 is closer to the lens 381 than the image display device 402 of FIG. Therefore, in the image display device 403 of FIG. 22, the degree of divergence is further wider than in the case of FIG.

  The user operates the adjustment unit 15 to adjust the distance between the display surface of the display unit 11 and the lens 381, so that any one of the image display devices 401 to 403 can be set.

  As shown in FIG. 20, by making the emitted light from the lens 381 into parallel light, the user can visually recognize that the light has arrived from infinity. As shown in FIG. 21 and FIG. 22, when the distance between the lens 381 and the display unit 11 is made closer, the virtual image optical distance becomes shorter and the image exists at a closer position (virtual image conversion distance). Allows the user to recognize larger images). The light observed by the user is closer to parallel light and closer to light from infinity, so that the user's feeling of fatigue is reduced. By setting the distance between the lens 381 and the display unit 11 so as to match the visual acuity of each user, it is possible to always display an appropriate image for each user. Further, it is possible to reduce eye strain by displaying an image at a distance even though the distance from the eyeball to the display device is relatively short. Furthermore, unlike a head-mounted display, it is not necessary to present it in contact with the eyeball, and a highly flexible display is possible.

  When a stereoscopic image is displayed (to be visually recognized by the user), an image photographed at the reference position (center position) is displayed in the display area 31A located substantially at the center, and the distance from the center is displayed in the surrounding display area 31A. An image in which the amount and direction of parallax change according to the direction is displayed.

  For example, in FIG. 2, the display area 31A on the right side of the center has a camera at a position away from the reference position on the right side (left side toward the subject) by a certain unit distance (for example, 1 cm). The image taken with is displayed. In the display area 31A on the four right sides of the center, the image is taken by the camera at a position that is four times the unit distance (4cm in this case) from the reference position to the right side (left side toward the subject) as viewed from the subject. The displayed image is displayed.

  Similarly, in FIG. 2, the display area 31A on the left side of the center is photographed by a camera at a position away from the reference position on the left side (right side toward the subject) by a unit distance (1 cm). The displayed image is displayed. In the display area 31A on the four left sides of the center, an image taken by the camera at a position separated from the reference position on the left side (right side toward the subject) by 4 times the unit distance (4 cm). Is displayed.

  The vertical relationship between the camera and the display area 31A is the same. That is, in FIG. 2, an image photographed by a camera at a position separated by a unit distance (1 cm) from the reference position is displayed in the display area 31 </ b> A that is one center above. In the display area 31 </ b> A four above the center, an image photographed by the camera at a position away from the reference position by four times the unit distance is displayed.

  Similarly, in FIG. 2, in the display area 31 </ b> A one lower than the center, an image photographed by a camera at a position away from the reference position by a unit distance (1 cm) from the subject is displayed. . In the display area 31A, which is four lower than the center, an image photographed by a camera located at a position lower than the subject when viewed from the subject by a distance of 4 times the unit distance (4 cm) is displayed.

  In other words, as shown in FIG. 23, m × n (3 × 3 in the embodiment of FIG. 23) cameras C11 to C33 arranged in a matrix with a unit distance (pitch interval) of 1 cm. Each of the 3 × 3 images photographed in FIG. 3 has display regions 31A11 to 3 × 3 corresponding positions (corresponding positions when the direction of the subject of the camera is matched with the display direction of the display element). It is displayed on 31A33.
