DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing and displaying method suitable for a video conference and the like and a display device used for the method. More specifically, when displaying multiple images photographed from different places or from different directions, a position where the displayed image is viewed. The present invention relates to a photographing display method and a display device that allow the user to view an image reproducing the place where the image was taken or the direction in which the image was taken through the display device as if in a real space.

[0002]

2. Description of the Related Art Hitherto, a video conference system has been constructed and put into practical use for remote communication between a plurality of interlocutors by video. As an example of this case, a case where a conference is held between two points X and Y shown in FIG. 12 for simplification of description will be described. At each of the points, one to a plurality of photographing devices and display devices are respectively installed. In the example, the photographing devices Xa, Xb, Xc at the X point and the display devices Y1, Y2, Y2 at the Y point.
Y3 corresponds to the photographing devices Ya, Yb, Yc and X at the Y point.
The display devices X1, X2, and X3 of the point correspond. For convenience, the photographing devices Xa, Xb, and Xc photograph the interlocutors XA, XB, and XC in front of the photographing devices, and the display device Y at the Y point.
The interlocutors XA, XB and XC are individually displayed on 1, Y2 and Y3.

FIGS. 13 (a) and 13 (b) are explanatory diagrams showing a state of a dialogue with the above configuration. Display device Y at Y point
Interactors YA, YB, YC in front of 1, Y2, Y3
By observing the above-mentioned display devices Y1, Y2, Y3, they will look at the interlocutors XA, XB, XC at the X point respectively. For example, in the case where the interlocutor YB interacts with the interlocutor XB, the interlocutor YB stares at each other while looking at each other (as shown in FIG. 13A, the interlocutor YB is through the display device Y2, and the interlocutor XB is through the display device X2). Can talk. However, as shown by the broken line in FIG. 12, if the interlocutor YB interacts with the interlocutor XC, the user shakes his head to the right instead of the display device of Y2.
3 will be seen on the display device XC. When the interlocutor XC faces the display device X2, the video of the interlocutor XC photographed by the photographing device Xc is displayed horizontally on the display device Y3 as shown in FIG. Will be interacted with the interlocutor XC displayed in FIG.

In order to compensate for such a situation in which the eyes of the interlocutors are deviated from each other, the image of the interlocutor XC is switched and displayed on the display device Y2, or any one of the X points is displayed on one display device. Instead of displaying only the image of the photographing device, many images of the interlocutors XB and XC are partially displayed,
A method in which the interlocutor YB selects and talks with the interlocutor at the X point has been considered.

On the other hand, a composite image obtained by vertically dividing and combining images from each photographing device is displayed on a focal plane of a microlens, and this is displayed on a lenticular killer used in a stereoscopic display device utilizing binocular parallax. There are also proposals to separate images by using a lens sheet.

[0006]

As described above, in the conventional video conference system, the interlocutor and the display device are one-to-one.
In the case of the method of talking in response to, although you can get the feeling of talking in real space, when talking with people other than the front, you will talk with people in an oblique figure, and in order to improve this, In a case where the display image is switched to an image captured from an oblique direction and displayed, for example, when the interlocutor YB changes the interlocutor from the interlocutor XB to the interlocutor XC using the display device Y2 in FIG. 12, the screen is manually changed. It is possible to switch the screen, detect the movement of the interlocutor, and automatically switch the screen by recognizing the voice of "Mr. C" or the like. However, the operation and the configuration are complicated, and the image relationship between the interlocutor and the background is always photographed by the photographing device in front of the display device. Also, in the case of a method of partially displaying multiple images on one display device, there is a drawback that the sense of reality is poor unlike a normal-size display because multiple images are reduced and displayed.

[0007] As described above, in the remote video conference of a large number of people according to the conventional method, when the people who interact with each other are exchanged, they talk with the obliquely-viewed video or photograph the video in front of themselves from different places and directions. There is a problem that the dialogue in an unnatural environment is more difficult than switching to the same place in order to switch to a different image or to select and talk to each other from among reduced multi-images .

On the other hand, in a display method using a lenticular killer lens sheet, an area where a separated image can be observed (observation area).
Changes depending on the distance between the lenticular killer lens sheet and the observer (interviewer), and when the distances are adjacent, the viewing area becomes narrower, and the display surface (lenticular killer lens sheet surface) and the observer (interactor) There is a problem that the distance is restricted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a photographing system that matches the eyes of interlocutors through a video image and realizes a display space that allows the user to enjoy a sense of interacting in the same place.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment according to the photographing and displaying method of the present invention. As a specific example, a case of a video conference system between a plurality of interlocutors will be described. For the sake of simplicity, the present embodiment describes a case of a trapezoidal micro prism sheet as a polygonal micro prism sheet, and a conference between two points X and Y shown in FIG.

A plurality of display devices X1, X2, X3, Y1, Y2, Y3 are placed between each of the two points X, Y, and subjects XA, XB, XC, YA, Y in front of each display device are placed.
A plurality of photographing devices (Xa _C , Xb _L ) for photographing B and YC,
(Xa _R , Xb _C , Xc _L ), (Xb _R , Xc _C ), (Y
_{a C, Yb R), (} Ya L, Yb C, Yc R), (Yb L, Y
c _C) to place. That is, the photographing device (Xa _C , X
b _L ) photographs the subject XA. (Xa _R , Xb _C , X
c _L ) is XB, (Xb _R , Xc _C ) is XC, (Ya _C , Yb)
_R) is _{YA, (Ya L, Yb C} , Yc R) is YB, (Y
b _L , Yc _C ) captures YC. Here, the suffix _C of the image capturing device captures an image in the front direction, _L indicates that the image is captured in the left direction, and _R indicates that the image is captured in the right direction. Further, a, b, and c indicate installation locations of the photographing devices corresponding to 1, 2, and 3 of the display device.

In this way, the images of the subject photographed by the plurality of photographing devices at each point are transmitted to the display devices at the other points and displayed. In this case, as described above,
The same subject is photographed by multiple photographing devices,
A plurality of videos of the same subject are synthesized and displayed on a display device at another location. The correspondence between the composite image and the display device is such that the composite image obtained by capturing the subject XA is displayed on the display device Y1.
Then, the subject YB is displayed on the display device Y2, the subject XC is displayed on the display device Y3, the subject YA is displayed on the display device X1, the subject YB is displayed on the display device X2, and the subject YC is displayed on the display device X3. It should be noted that the meaning of “absent” in the figure indicates that there is no image of the photographing device included in the composite image, and specifically means that a black image or an adjacent image is used.

FIG. 2 shows the display device Y2 and the interlocutors YA, YB, and Y2 when the display surfaces of the display devices Y1, Y2, and Y3 at the point Y in FIG. 1 are set up along the line LL '. Y
The relationship of C is mainly shown. The interlocutor XB at the X point and the interlocutors YA, YB, Y at the Y point displayed on the display device Y2.
When C interacts, the interlocutors YA, YB, and YC can talk while forgoing by shaking their heads to the right, facing the front, or shaking their heads to the left from their respective positions. . The optimum azimuth angle γ to be swung will be described later in the description of the small trapezoidal prism sheet in FIG.

As shown in FIG. 2, the structure of the display device according to the first aspect of the present invention is such that images taken by changing the photographing angle by a photographing device in which the same subject is installed in different places are vertically divided. A configuration is adopted in which trapezoidal minute prisms corresponding to the combined minimum unit set image 3 are displayed through the small trapezoidal prism sheet 1 having a shape repeated by the number of sets of the set images constituting the composite image. In this embodiment, the incident light of the display image of the small trapezoidal prism sheet 1 is once projected on a semi-light-shielding screen sheet 2 which is close to or in close contact with the small trapezoidal prism sheet 1, and the image is projected by the small trapezoidal prism sheet 1 in three directions. The video is separated. Described on the display surface of the display device in the figure [...]
Indicates an arrangement order when a composite image is created from images from the respective photographing apparatuses. For example, [Xa _R Xb _C Xc _L ] is X
And images of the image from the imaging device Xa _R disposed in place of a, from the photographing apparatus Xb _C disposed in place of b at the point,
This shows that the images from the photographing apparatus Xc _L arranged at the location c are vertically divided, arranged side by side, and synthesized. The three images making up this one composite image 4 are separated and displayed by the action of the micro prism sheet 1 in the directions of the interlocutors YA, YB, YC corresponding to the shooting directions of the shooting device.

The synthesized image 4 is displayed on a liquid crystal valve 5 or the like, and this image is enlarged and projected on the semi-light-shielding screen sheet 2. If the image pitch matches the trapezoidal pitch p of the small trapezoidal prism sheet 1, the small trapezoidal prism sheet 1 may be directly joined to the image display surface.

Next, a description will be given of a method of creating a composite image in which images obtained by photographing the same subject from different angles are vertically divided and combined, together with the correspondence relationship with the small trapezoidal prism sheet 1 in FIG. 3A and 3B show a specific example of the small trapezoidal prism sheet 1 together with the semi-light-shielding screen sheet 2. FIG. FIG. 3 shows the shape of the micro trapezoidal prism sheet 1 as viewed from directly above. FIG. 3A shows a concave trapezoidal shape with respect to the light incident on the minute trapezoidal prism sheet.
(B) has a convex trapezoidal shape, and images R, C, and L (subscripts) obtained by photographing the same subject from different angles are respectively n vertically elongated image pieces R _i , C _i , and L _i ( _i = 1, ... ,,
When creating a composite video in which video segments are combined by vertically dividing into n), the combination order is different.

In the case of the concave trapezoidal small trapezoidal prism sheet 1 shown in FIG. 3 (a), an image R from a photographing device for photographing the same subject from the right, an image C from a photographing device for photographing from the front, and a leftward direction The images L from the photographing device to be photographed are vertically divided and combined in order, and the image pitch of the combined image of the minimum unit of the combination is set to the trapezoidal pitch p of the small trapezoidal prism sheet.
The composite image is converted to a small trapezoidal prism sheet 1
Incident on At this time, the prism surfaces r, c, l in FIG.
Are allocated to the video pieces obtained by vertically dividing the video images R, C, and L. In the case of a convex trapezoidal small trapezoidal prism sheet, the image L from the photographing device photographing the same subject from the left, the image C from the photographing device photographing from the front, and the image R from the photographing device photographing from the right are each vertically arranged. The composite image divided and combined is incident on the small trapezoidal prism sheet 1. At this time, the images L, c on the prism surfaces l, c, r in FIG.
A vertically divided video fragment of C and R is assigned. Assuming that the trapezoidal base angle θ of the small trapezoidal prism sheet 1 and the refractive index n of the material are:
The optimum azimuth angle γ (see FIG. 2) for viewing a display image through the small trapezoidal prism sheet 1 is γ = sin ⁻¹ [n · sin (θ−sin ⁻¹ (sin θ /
n))].

When creating a composite video, video fragments R _i , C _i , L _i ( _i = 1,..., By vertical division of videos R, C, L taken of the same subject from different directions) n) is compressed in the horizontal direction so that each is reduced to 1/3, and a first method is used in which all the image pieces are used (as an example, the case of the concave trapezoidal micro trapezoidal prism sheet of FIG. 3A is used as an example). As shown, R
₁ C ₁ L ₁ R ₂ C ₂ L ₂ ...), And a second method of compressing by a factor of 2 and using all video pieces (R ₁ R ₁ C as a line)
_{1 C 1 L 1 L 1 R} 2 R 2 C 2 C 2 L 2 L 2 ······), 2 present was one by removing from a video _{piece, R 1 C 2 L 3 R} 4 C 5 L 6 as well as・
Various methods such as a third method using... Are conceivable. In the first and second methods, since all the image pieces are used, the resolution does not decrease as a display image.
Although the method of (1) is easy to make, the resolution is reduced. Therefore, the selection may be made according to the purpose of use.

4 (a) and 4 (b), a light-shielding film stripe 6 is provided in the semi-light-shielding screen sheet 2 of FIG. FIG. By aligning the division boundary of the composite image with the light-shielding film stripe 6 and each trapezoidal corner of the small trapezoidal prism sheet 1, and combining the vertically divided divided composite image into the small trapezoidal prism sheet 1, the light is blocked. The film stripe 6 has an effect of increasing the separability when separating into three-directional images, and becomes a black stripe that separates vertically separated images. 4 (a) corresponds to FIG. 3 (a), and FIG. 4 (b) corresponds to FIG. 3 (b).

FIGS. 5A and 5B show a configuration in which the black stripe function is directly added to the micro trapezoidal prism sheet 1 instead of the semi-light-shielding screen sheet 2. FIG. That is, since it is a small trapezoidal prism sheet 1 provided with a light shielding film stripe 7 that shields a part of the divided image near each corner of the trapezoid, unlike the case of FIG. There is an advantage that the alignment of 1 is unnecessary. In FIG. 5, FIG.
FIG. 3B corresponds to FIG. 3A and FIG.

As a method of improving the separability at the time of displaying a composite image, other than the method of providing a black stripe on the display device side as shown in FIGS. 4 and 5, when synthesizing images R, C, and L, Alternatively, a method may be used in which a black striped video piece is inserted between the video pieces R _i , C _i , and L _i and synthesized.

In the embodiment of the first aspect of the present invention, the image signals corresponding to the respective images obtained by changing the photographing angle by the photographing apparatus in which the same subject is installed at different places are divided and synthesized. That is, a sequence (synthesized image) of a minimum unit image 3 formed by vertically dividing the respective images and combining them is displayed on a liquid crystal valve or the like 5 and enlarged and projected on a small trapezoidal prism sheet of a display device. The composite image is displayed on a direct-view image display surface, and this display surface is directly joined to the small trapezoidal prism sheet 1.

[Embodiment of the Invention According to Claim 2] The structure of the display device according to claim 2 of the present invention is such that each image obtained by shooting the same subject at different shooting angles by a shooting device installed at a different place. The image signal is not divided and synthesized to form the set image 3, but is directly enlarged and projected on the small trapezoidal prism sheet of the display device to synthesize and display each image on the small trapezoidal prism sheet. Is what you do.

[Extended Example of Embodiment of the Present Invention] In the video communication by the photographing and displaying method of the present invention, a case of a conference between two points is taken up for the sake of simplicity of explanation, and the line of sight of the talking parties can be matched. However, the number of communication points is not particularly limited.

In the embodiment of the present invention, the explanation has been given based on the video conference system between a plurality of interlocutors.
In particular, the present invention is not limited to the video conference system, and in the case of different point-to-point communication using images, when viewing images with different viewpoints through display devices at different points,
The direction in which the user views the display device corresponds to the direction in which the subject is photographed from the photographing device. In other words, video communication with a sense of realism is realized as if the subject were viewed from the installation point of the photographing device.

Further, when a video from each photographing device is vertically divided and a combined video is formed by combining the vertically divided videos, the composite is performed at the photographing point side and the composite video signal is transmitted to the display point side. Alternatively, each photographed image may be transmitted from the photographing point side to the display point side, and may be formed into a composite image at the display point side.

In this embodiment, the number of locations of the photographing devices and the number of display devices at each point have been described as three. However, since the polygonal shape of the small polygonal prism sheet is trapezoidal, it matches the display of a three-way image. I have. However, in the case of this trapezoidal shape, when the number of image capturing device installation locations and the number of display devices at each point are two, it is only necessary to create a composite image by vertically dividing and combining the image from the two image capturing devices and the black image. In the case of 4 or more, three images are extracted by matching the viewing direction angle with respect to the display device of the interlocutor who views the display device at the display point side and the shooting direction angle with respect to the subject of the shooting device at the shooting point side. What is necessary is just to divide the video vertically and perform combination synthesis.

In the first and second aspects of the present invention, if the number of corners of one polygon of the minute polygonal prism is an m-sided polygon, an image is formed on m-1 sides excluding the bottom side. Can be incident. In the case of a small trapezoidal prism, the number of corners of the trapezoid is quadrangular, and three sides r, c, l excluding the bottom side
The image is incident on. In the case where the m-sided polygonal prism sheet of the present invention is applied, the number of installation locations and the number of display devices are m-1 in the above-described embodiment, and each installation location is m-1 at that point. In the direction of the subject in front of the display devices, m-
One photographing device is installed, and as in the above embodiment,
A composite image may be created from a maximum of m-1 captured images for the same subject and displayed on a corresponding display device at another point. When a light-shielding film stripe having the black stripe function is provided, the position of each polygonal corner is adjusted in the same manner as in the case of a trapezoid.

According to the fourth and fifth aspects of the present invention,
In the above embodiment, the number of directions for photographing the same subject in different directions is set to three, and the minute polygonal prism is described as the minute trapezoidal prism. However, when imaging the m direction when shooting the same subject, the inclined surface according to claim 4, 5 one one prism of the same set angle successive prism face at the fine polygonal prism in the embodiment described the same vertical plane 2
Of the prism surfaces of each surface, the inclination angles of the inclined surfaces constituting each prism of the set of the same angle continuous prism surfaces are changed, in other words, the angle θ of the prism surface of each set (see FIG. 9 and the angles shown in FIG. 10 may be changed in accordance with the shooting direction, and a minute polygonal prism may be formed from a set of m types of same-angle continuous prism surfaces. A micro-polygonal prism sheet is developed in the form of a display screen with a minimum unit image pitch p). When an image is projected on the minute polygonal prism sheet, if the image pitch p of the combined image is not constant near the center and the periphery of the minute polygonal prism sheet due to optical distortion of the projection system, etc. It is necessary to change the repetition pitch p of the rectangular prism. If the incident angle of each projected image is different between the vicinity of the center and the periphery of the micro-polygonal prism sheet, the same micro-polygonal prism is repeated to produce a micro-polygonal prism sheet without forming the micro-polygonal prism sheet. It is also possible to manufacture the prism by slightly changing the angle θ of each set of prism surfaces in the m kinds of sets in the prism with respect to the shooting direction.

In FIG. 2 of this embodiment, each display device is arranged so that the display surfaces of the left and right display devices Y1 and Y3 are aligned with the display surface of the display device Y2. 'It may be arranged at an angle without being aligned on the top. For example, FIG. 11 shows another embodiment in which the components are arranged at an angle of γ. In this case, the order in which the video pieces obtained by photographing the same subject from different angles and which are vertically divided and the black video pieces and the like as “nothing” video are arranged in a different order on the small trapezoidal prism sheet is different. In the device Y1, [No Xa _C
Xb _L ] is [Xa _C Xb _L No] in FIG. 11 and [Xb _R Xc _C No] is shown in FIG. 1 on the right display device Y1 in FIG.
In the case of 1, it becomes [No Xb _R Xc _C ].

In the above embodiment, the case where the base angle θ of the small trapezoidal prism sheet 1 is 45 degrees has been described, but it is determined in consideration of the refractive index n of the sheet material, the direction angle of the photographing apparatus with respect to the subject, and the like. do it. As a material, an acrylic material can be used in terms of processability, light transmittance, uniformity, low cost, and the like. However, the material is not particularly limited, and a material excellent in light transmittance and expansion resistance is desirable.

The polygon pitch p of the micro polygonal prism sheet is set such that when the image pitch of the minimum unit image combined in the vertical division is almost equal over the entire display image,
The pitch may be uniform over the entire surface of the sheet. However, in the case where the degree of oblique incidence of the synthesized image as it moves away from the center of the display image to the left and right is large, for example, the vertical light (small polygon prism sheet) is provided by a Fresnel lens sheet or the like in front of the small polygon prism sheet. (The incident angle α is 90 degrees). Even in this case, if the video pitch of the combined video increases as the distance from the center of the display video increases left and right,
The polygon pitch p of the micro-polygonal prism sheet must also match the image pitch of the set image, and is not necessarily limited to a uniform pitch over the entire surface of the sheet.

When the size of the image displayed on the display device is generally as large as several tens of inches to several hundreds of inches, the image is displayed in a display mode using a projection display system such as a liquid crystal projector. In this case, it is apparent that it is desirable that the synthesized image projected on the minute polygonal prism sheet should be almost uniformly and perpendicularly incident on the prism sheet depending on the design of the light source, the liquid crystal bulb, and the optical system.

In the embodiments shown in FIGS. 2, 3, 4, 5, 9, and 10, a semi-light-shielding screen sheet which is close to or in close contact with a small trapezoidal prism sheet is provided between the display device and the small trapezoidal prism sheet. Has been shown. However, the functions of the semi-light-shielding screen sheet and the micro-trapezoidal prism sheet as in the above-described embodiment can be realized by one micro-trapezoidal prism sheet by using the micro-trapezoidal prism sheet whose trapezoidal surface is subjected to the semi-light-shielding screen processing. In this case, it is obvious that the black stripe function can be realized by a small trapezoidal prism sheet provided near each corner of the trapezoid as shown in FIG.

In the embodiments of FIGS. 2, 3, 4, 5, 9, and 10, the composite image on the small trapezoidal prism sheet is set to the incident light path, and the semi-shielding screen sheet is set to the small trapezoidal shape. Although arranged in front of the prism sheet, as another embodiment, a semi-shielding screen sheet is arranged on the back side of the entrance surface of the small trapezoidal prism sheet so that the image forming distance of the synthesized image is adjusted to the semi-shielding screen, or an independent half-screen is used. It is also possible to apply a semi-light-shielding screen treatment to the back surface (not the prism surface on the incident light side but the output light surface) of the micro trapezoidal prism sheet without providing the light-shielding screen sheet. Further, if it is not necessary to make uniform light unevenness a problem, it is necessary to use a semi-light-shielding screen sheet, a trapezoidal surface of a small trapezoidal prism sheet (a prism surface on an incident light side) or a back surface of a small trapezoidal prism sheet (an incident light side). It is not necessary to subject the output light surface (not the light-side prism surface) to a semi-shielding screen treatment.

Further, when the micro trapezoidal prism sheet of the above embodiment is generally made into a micro polygonal prism sheet, as described above, a semi-light-shielding screen sheet may be used,
Even if the polygonal surface (the prism surface on the incident light side) or the back surface (the output light surface instead of the prism surface on the incident light side) of the minute polygonal prism sheet is subjected to semi-light-shielding screen processing without using the semi-light-shielding screen sheet. The same is possible. If uniform light unevenness does not have to be a problem, it is necessary to use a semi-light-shielding screen sheet, or perform a semi-light-shielding screen treatment on the polygonal front surface and the back surface of the minute polygonal prism sheet. No need. As described above, the present invention can be applied variously according to the gist and can take various embodiments.

[Expansion Example of the Embodiment of the Small Trapezoidal Prism Sheet According to the Fourth and Fifth Embodiments] The two types of sheet, the small trapezoidal prism sheet according to the fourth and fifth aspects and a flat sheet, are used to form the former small trapezoidal prism sheet. The uneven prism surface of the prism sheet and the plane of the latter flat sheet are opposed to each other, a transparent electrode film is formed on both opposing surfaces, the polymer liquid crystal is sandwiched, and the diffusion state of the polymer liquid crystal is controlled by controlling the voltage of the transparent electrode. And a transmissive state corresponding to the refractive index n of the prism sheet, and the sheet of this composite structure is alternately time-divisionally controlled between the transmissive state and the diffused state. The function can be taken by a photographing device, and in the diffused state, the function of a semi-light-shielding screen is provided while leaving the refraction of the small trapezoidal prism sheet. And it can be applied as the display screen 2. In this case, the use of the small trapezoidal prism sheet according to the fourth and fifth aspects of the invention makes it possible to reduce the size of the small trapezoidal prism sheet as compared with the case of using the small trapezoidal prism sheet according to the first, second and third embodiments. Since the unevenness is small, the electric field distribution to the polymer liquid crystal by controlling the voltage of the transparent electrode is relatively uniform, the transmittance is improved, and the image quality of an image passing through the display screen is improved.

In the case where the composite structure sheet (a sheet for controlling the transmission and diffusion of voltage by controlling a polymer liquid crystal sandwiched between two kinds of sheets, a micro trapezoidal prism sheet and a flat sheet), is applied to the display screen of claim 3. When utilizing the refraction effect of the small trapezoidal prism of the display screen at the time of photographing, unlike the above in the composite structure sheet, the refractive index of the polymer liquid crystal does not match the refractive index n of the prism sheet. It is necessary to select a polymer liquid crystal material so as to be in a transmission state while leaving a refraction effect. Alternatively, unlike the case of the sheet having the composite structure, the opposite two surfaces of the two types of sheets, the micro trapezoidal prism sheet and the flat sheet, are different from the above-mentioned sheet of the composite trapezoidal prism sheet, and the flat surface of the former micro trapezoidal prism sheet without unevenness and the latter flat sheet A transparent electrode film is formed on the two opposing planes by sandwiching the polymer liquid crystal in the same manner as described above, and a composite structure in which the diffusion state and the transmission state of the polymer liquid crystal are created by controlling the voltage of the transparent electrode. A similar purpose can be achieved with a sheet.

As described above, in the shooting and displaying method according to the present invention, in a shot image in a remote place and the display of the image, the same image in different directions from a different place by using a plurality of image pickup devices is claimed. According to the first aspect of the present invention, a composite image is formed by vertically dividing each of the captured images and combining them. In a display device at a remote place, a minimum unit set in which polygonal minute prisms are vertically divided and combined. This composite image is displayed through a micro-polygonal prism sheet with a shape that is repeated by the number of sets of the composite image that corresponds to the image and achieves the composite image. By viewing the display image of the device from different places and from different angles, it is possible to directly view the subject in the real space from the point where the imaging device is installed. Solving it is possible to see the display image.

According to the second aspect of the present invention, in a display device at a remote location, each of the photographed images is projected onto the minute polygonal prism sheet by a projection device provided for a plurality of photographing devices, and is projected on the minute polygonal prism sheet. In order to display the composite video, the composite processing on the video signal is unnecessary, the displayed video is separated into directions corresponding to shooting, and the display video of this display device is viewed from different places and different angles, so that the shooting device From the point where is installed, the displayed image can be viewed as if the subject is directly viewed in the real space.

According to the third aspect of the present invention, in the display device located at a remote place, the plurality of photographing devices each photograph a subject (an interlocutor) having a different direction through a minute polygonal prism sheet disposed in front thereof. The number of photographing devices can be reduced by creating a composite image as a set of vertically divided image pieces of images obtained by photographing the same subject from different directions by vertically dividing the photographed images, and a display device at a remote location By displaying this composite image through a display screen consisting of a small polygonal prism sheet in the above, a multi-directional image taken through the small polygonal prism sheet can be separated and viewed as a display image corresponding to that direction, Display images on the display device in different places,
By viewing from different angles, it is possible to watch the displayed image from the point where the photographing device is installed, as if the subject were viewed directly in the real space.

[0062] small polygonal prism according to claim 4, 5 the described invention, an image obtained by photographing the same subject from different directions to show through fine polygonal prism sheet is an aggregate of minute polygon prism, displayed in isolation Since it is possible to see an image, it has the same function as the micro-polygonal prism in claims 1, 2 and 3 optically, but one prism surface is realized by a set of the same angle continuous prism surfaces. Therefore, unevenness can be reduced in the incident direction of the projected image, and a light-shielding film stripe for separating vertically divided images of different images and preventing leakage can be easily formed only on the convex portion of the uneven surface. Alternatively, even if a part of the light-shielding film stripe is formed in the concave portion, almost all of the light-shielding film stripe can be formed on the convex portion. Further, since the light-shielding film stripes can be formed directly on the minute polygonal prisms, there is no need to form the light-shielding film stripes on the semi-light-shielding screen sheet to match each prism surface of the minute polygonal prism sheet, and there is no fear of misalignment. . Further, in the minute polygonal prism according to the first, second and third aspects, if the number of polygons of the minute polygonal prism is an m-sided polygon, the minute polygonal prism has m-1 prism surfaces excluding the base, and m = becomes a trapezoidal prism when the 4, but m is becomes 5 or more prism surface is required to process angle may each prism surface is at least four sides, claim 4, 5
In the micro-polygonal prism according to the invention described above, each prism of the set of the same angle continuous prism faces is composed of two prism faces having the same vertical face and inclined face, and one of the sets of the same angle continuous prism faces is provided. By changing the inclination angle of the inclined surface constituting each prism, a micro polygonal prism optically the same as the micro polygonal prism in the first, second and third aspects can be easily realized.

When the incident angle of each projected image is different between the vicinity of the center and the periphery of the small polygonal prism sheet,
Without repeating the same micro-polygonal prism to produce a micro-polygonal prism sheet, the direction in which the angle of the inclined surface of each set of prism surfaces in the m types of sets in the micro-polygonal prism was photographed. In contrast, it is only necessary to make it with a slight modification, and it can be easily dealt with.

Further, since the micro-polygonal prism sheets of the fourth and fifth aspects have smaller irregularities than the micro-polygonal prism sheets of the first, second and third embodiments, the present prism When a sheet is used to sandwich the polymer liquid crystal to form a sheet for controlling the transmission and diffusion of the polymer liquid crystal by controlling the voltage of the transparent electrode and use it as a display screen, the electric field distribution becomes relatively uniform and the transparency is improved. The image quality of the captured video through the display screen is improved.
