Description

  The present invention relates to a ciliary muscle relaxation device that induces relaxation of ciliary muscles.

  Conventionally, there is a stereo test using an instrument as shown in FIG. 13 as an ophthalmic examination using a binocular vision image in which different images are visually recognized by an observer's right eye and left eye. In this ophthalmic examination, the right-eye filter and the left-eye filter are worn with glasses 1000 of different colors, and a binocular separation image is viewed to determine whether or not there is a stereoscopic function and to measure the ability of the stereoscopic function. Is going.

  In the discrimination test of the stereoscopic function, a stereoscopic image 1001 with a parallax of 3600 seconds is observed as a viewing angle for an observer to view a binocular separated image, and it is judged whether the binocular separated image 1001 looks stereoscopic. The reason why a stereoscopic image with a parallax of 3600 seconds is used as a viewing angle for the observer to see is that a healthy person can be surely determined to be a stereoscopic image.

  Further, in the capability measurement of the stereoscopic function, a stereoscopic image with a parallax of 40 seconds to 800 seconds is observed as a viewing angle for the observer to view the binocular separated image 1002, and the minimum parallax that can identify the stereoscopic is measured. The reason why a stereoscopic image with a parallax of 40 seconds to 800 seconds is used as a viewing angle for the observer to view is to measure how fine a solid can be recognized.

Furthermore, as a technique using parallax of an image, there is a recovery display device such as eye strain as shown in Patent Document 1 below. This display system for recovery from eyestrain induces relaxation or tension of ciliary muscles by means of convergence adjustment associated with movement of a target by a stereoscopic image and subjective perspective of the image. Specifically, the amount of parallax for viewing the target is changed by moving the target displayed as an image. Thereby, after inducing the tension of the ciliary muscles of the observer, the tension state is returned to the normal state, and the movement imitating the stretch is induced.
JP 2003-325605 A

  However, in the above-described display device, the ciliary muscle is forcibly tensioned from a normal state as disclosed in FIG. It only induces a relaxed movement in the state and simply changes the ciliary muscles between the normal state and the tension state.

  Therefore, the present invention has been proposed in view of the above-described circumstances, and an object thereof is to provide a ciliary muscle relaxation device that can induce relaxation of ciliary muscles with a simpler configuration. And

As a result of research, the inventor of the present application, when the viewing angle of the observer for viewing the binocular separation image is in the range of 2000 seconds to 3000 seconds, the observer is more than when viewing the binocular separation image at other viewing angles. We found that the ciliary muscles relaxed. Therefore, the present invention has been obtained from such a knowledge, and in order to solve the above-mentioned problems, the present invention is composed of arbitrary images to induce relaxation of the observer's ciliary muscle. the that optotypes, any viewing angle within range of a presentation section for presenting separated in correspondence with both eyes, the observer's viewing angle for viewing the previous SL optotypes from 2 000 seconds to 3000 seconds anda section that adjusts the parallax amount of dichoptic image so that the dichoptic image of the visual Saryou, and with the indicator characterized in that Hisage Shimesuru the presentation unit is there.

  According to the present invention, the binocular separated image having a parallax amount with any viewing angle within the range of 2000 seconds to 3000 seconds is presented as a visual target, so that relaxation of the ciliary muscle is induced with a simpler configuration. Therefore, it can be used for eye strain of the observer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The ciliary muscle relaxation device to which the present invention is applied induces the observer to relax the ciliary muscle of the observer from the normal state by visually recognizing the image.

  As shown in FIG. 1, the structure of the eye adjusts the thickness of the crystalline lens by applying ciliary muscle pressure to the crystalline lens. The crystalline lens corresponds to a transparent convex lens portion in the eye, and adjusts the focus of the light that has entered the crystalline lens and projects it on the retina. This light focus adjustment is performed by the ciliary muscle adjusting the thickness of the crystalline lens, and the observer adjusts the visual acuity in the distance and the distance. In the myopic state, the ciliary muscles become tense and the lens becomes thicker. In the farsighted state, the ciliary muscles relax and the lens returns to its original thickness.

  Further, when viewing the binocular separated image obtained by separating the images that can be seen by the left eye and the right eye, the observer sees the binocular separated image at a viewing angle as shown in FIG. The viewing angle is determined by using the center point of the line segment connecting the left eye position and the right eye position of the observer as the viewpoint position, and the line segment connecting the viewpoint position and the left eye image, the viewpoint position, and the right eye image. It is the angle formed by the line segment connecting In a visual function test or the like, since a finer viewing angle is handled, 1 ° of the viewing angle is represented as 60 minutes, and the viewing angle is adjusted by representing 60 minutes as 3600 seconds. Therefore, the ciliary muscle relaxation device to which the present invention is applied has the parallax amount that is the interval between the left-eye image and the right-eye image in a specific range, which will be described later, so that the left-eye image and the right-eye image are obtained. The viewing angle [seconds] for viewing the binocular separation image composed of the image for use can be set to a specific range.

  The ciliary muscle relaxation device to which the present invention is applied is shown in FIG. 3 and FIG. 4 obtained by the research of the inventor of the present application. As a result of measuring the adjustment response of the observer's lens during stereoscopic image observation, the viewing angle is It was confirmed that the ciliary muscle was more relaxed when viewing an image with a parallax amount in the range of 2000 seconds to 3000 seconds than when viewing the image at other viewing angles. " It is used. The relationship between the viewing angle [second] and the adjustment degree (D) of the ciliary muscle shown in FIG. 3 shows changes in the ciliary muscle and lens of the right eye when the observer gazes at the stereoscopic image. The relationship between the viewing angle [second] and the adjustment degree (D) of the ciliary muscle shown in FIG. 4 indicates changes in the ciliary muscle and lens of the left eye when the observer gazes at the stereoscopic image.

  Here, the ciliary muscle adjusts and tensions when a nearby object is watched, and deforms the lens in the direction of increasing the thickness. On the other hand, the ciliary muscle adjusts and relaxes when a distant object is watched, resulting in a thin lens. Further, when the observer gazes at the stereoscopic image, as shown in FIGS. 3 and 4, the viewing angle is recognized as binocular parallax (crossing parallax) in the range of 2000 to 3000 seconds (aa ′). The degree of relaxation of the ciliary muscle when stereoscopically viewed is significantly higher than the degree of relaxation of the ciliary muscle when a stereoscopic effect with zero parallax is not obtained. In other words, the ciliary muscles are relaxed as if looking at a distant place, even though a stereoscopic effect is felt at a viewing angle of 2000 seconds to 3000 seconds.

  Based on such changes in the ciliary muscle, the ciliary muscle relaxation device to which the present invention is applied has a viewing angle of 2000 to 3000 seconds when the observer's viewing angle for viewing the visual target is within the range. The relaxation of the ciliary muscle is induced by utilizing the fact that the degree of relaxation of the ciliary muscle is larger than when the visual target is viewed at the viewing angle.

  There are an anaglyph method, a polarization method, a time division method, and the like as a method for presenting a binocular separation image and presenting a stereoscopic image. Among these, FIG. 5 shows a configuration of the presentation unit 1 using an anaglyph method as a ciliary muscle relaxation device to which the present invention is applied. In the anaglyph method, the left eye and the right eye of the observer are fitted with filter glasses 2 having a left eye filter (red) 2L and a right eye filter (blue) 2R, respectively, on the presentation unit 1 such as white paper. The binocular separation image composed of the left-eye image (blue) 102 and the right-eye image (red) 103 depicted in FIG. The binocular separated images 102 and 103 are still images, and the interval and size thereof are not changed, and the display position in the presentation unit 1 is not moved (translated or rotated).

  Further, the left-eye filter (red) 2L and the right-eye filter (blue) 2R need to be configured with a translucent color so that the observer can perceive the shape of the overlapping portion on the presentation unit 1 as well. is there. For example, the overlapping portion can be made to perceive the shape of the overlapped portion by cutting cellophane into a predetermined target shape and placing it on white paper. The left eye and right eye filters may be other combinations such as red and green and red and cyan.

  With such a configuration, by allowing the observer to observe the binocular separated images 102 and 103, binocular separation can be realized and the stereoscopic image 101 can be presented to the observer. That is, the red right-eye image 103 can only be seen through the blue filter 2R, and the blue binocular separated images 102 and 103 can only be seen through the red filter 2L. .

  Therefore, according to this ciliary muscle relaxation device, the line of sight 3R viewing the right eye image 103 via the blue filter 2R and the line of sight 3L viewing the right eye image 103 via the red filter 2L intersect. At the point 101a on the image 101, the angle formed by the line of sight 3L and the line of sight 3R is the viewing angle of the observer. Therefore, by adjusting the interval between the left-eye image 102 and the right-eye image 103 on the presentation unit 1 so that the viewing angle is any of 2000 seconds to 3000 seconds, the observer's hair Can induce relaxation of body muscles.

  Here, the viewing angle of the observer is expressed by an angle formed by an angle formed by the left eye line of sight 3L and the right eye line of sight 3R connecting the observer's viewpoint position and the binocular separated images 102 and 103. For this reason, in order to use the ciliary muscle relaxation device, it is necessary to limit the viewpoint position with respect to the presentation unit 1. The viewpoint position with respect to the presentation unit 1 is set at a position 40 cm away from the presentation unit 1 assuming a distance between the viewer's viewpoint position when reading a normal book and the book. In this case, the parallax amount of the binocular separated images 102 and 103 when the viewing angle of the observer when viewing the binocular separated images 102 and 103 is 2000 to 3000 seconds is drawn on the white paper presentation unit 1. When converted in terms of the distance between the binocular separated images 102 and 103, the distance is approximately 15.5 mm to 23.3 mm.

  The distance S between the binocular separated images 102 and 103 with respect to the distance D between the presenting unit 1 and the viewpoint position is expressed by the following formula 1.

S = 2 × D × tan (θ / 2)
Here, θ in the above formula is a viewing angle (°). Therefore, when it is desired to change the distance D between the presentation unit 1 and the viewpoint position, the viewing angle θ is set to any angle between 2000 seconds and 3000 seconds, and the distance S between the binocular separated images 102 and 103 is changed. Accordingly, even when the binocular separated images 102 and 103 are viewed from the distance D between the arbitrary presentation unit 1 and the viewpoint position, the distance S between the binocular separated images 102 and 103 is adjusted to be 2000 seconds to 3000 seconds. The binocular separated images 102 and 103 can be viewed at any viewing angle θ.

  Note that the visual target represented by the binocular separation images 102 and 103 may be a simple shape such as a rhombus, a circle, or a cross as shown in FIG. 5 and may have a size that can be perceived by an observer. In the example shown in FIG. 5, a rhombus shape that is visually recognized at a viewing angle of 5 ° is adopted as the binocular separated images 102 and 103.

  Further, the target may be a face, a bear, or a car as shown in FIG. However, it is desirable that the binocular separated images 102 and 103 have the same shape because the left eye image 102 and the right eye image 103 desirably have a shape capable of fusing the binocular separated image.

  As described above, the ciliary muscle relaxation device to which the present invention is applied corresponds to a binocular vision target composed of arbitrary images in order to induce relaxation of the observer's ciliary muscle. And a presentation unit 1 for separating and presenting. Then, the ciliary muscle relaxation device uses the presenting unit 1 to display a binocular separated image having a parallax amount with the viewing angle of the observer for viewing the optotype as any viewing angle within a range from 2000 seconds to 3000 seconds. Can be presented as a visual target. Therefore, according to this ciliary muscle relaxation device, relaxation of the ciliary muscles of the observer can be induced only by observing the binocular separated images 102 and 103 drawn on the presentation unit 1. Therefore, according to this ciliary muscle relaxation device, it is possible to cause eye fatigue or the like by simply allowing the observer to wear the filter glasses 2 and see the binocular separated images 102 and 103 on the presentation unit 1 in a normal posture. An effect such as recovery can be obtained.

  Moreover, according to this ciliary muscle relaxation device, the binocular separated images 102 and 103 are constituted by the presentation unit 1 and the filter glasses 2 as a configuration for visually recognizing at any viewing angle of 2000 seconds to 3000 seconds. A simple configuration such as an anaglyph method can be obtained. Therefore, the configuration does not become large.

  Next, the configuration of another ciliary muscle relaxing device that can induce relaxation of the observer's ciliary muscle as described above will be described.

  The ciliary muscle relaxation device shown in FIG. 7 forms a booklet 10 by drawing binocular separated images 102 and 103 on each of a plurality of presentation sheets 1A, 1B, 1C, and 1D. The binocular separated images 102 and 103 drawn on the presentation units 1A, 1B, 1C, and 1D are observed by the observer at different viewing angles within the range of 2000 seconds to 3000 seconds. The interval between the binocular separated images 102 and 103 is adjusted.

  The amount of change in the amount of parallax between the binocular separated images 102 and 103 is not particularly limited, but the binocular separated images 102 and 103 having a 1001 pattern in which the viewing angle is changed by 1 second may be created. Eleven patterns of binocular separation images 102 and 103 may be created.

  Then, the binocular separated images 102 and 103 selected from the plurality of binocular separated images 102 and 103 by the observer from the presentation units 1A, 1B, 1C, and 1D constituting the booklet 10 are presented. can do. Specifically, when binocular separated images 102 and 103 with different amounts of parallax are described on a plurality of pages and the binocular separated images 102 and 103 with a specific amount of parallax are to be presented, the corresponding pages should be opened. It becomes.

  In the example shown in FIG. 7, the binocular separated images 102 and 103 have the same shape. However, as shown in FIG. 8, the binocular separated images 102 and 103 have different shapes depending on the amount of parallax. It may be a pattern such as a face, a bear, or a car. However, it is desirable that the binocular separated images 102 and 103 have the same shape because the left eye image 102 and the right eye image 103 desirably have a shape capable of fusing the binocular separated image.

  According to such a ciliary muscle relaxation device, a plurality of binocular separated images 102 and 103 having different parallax amounts for viewing by an observer can be prepared and selected. Thereby, although there are individual differences in the amount of parallax between the binocular separated images 102 and 103 in which the effect of relaxing the ciliary muscle is maximized, the binocular separated images 102 and 103 having a plurality of different parallax amounts set in advance. A function of selecting a specific one out of 103 is provided. Thus, by viewing the binocular separated images 102 and 103 having a parallax amount suitable for the observer, the binocular separated image 102 with the viewing angle most effective for the observer even within the range of 2000 seconds to 3000 seconds. , 103 can be given a relaxing effect on the ciliary muscle.

  Further, when the binocular separated images 102 and 103 having different parallax amounts are sequentially viewed, the thickness of the observer's crystalline lens is measured by a visual function testing device, and the most effective ciliary muscle relaxation effect appears. Alternatively, the binocular separated images 102 and 103 may be obtained. Thereby, even if the parallax amount of the binocular separation images 102 and 103 from which the relaxation effect of the ciliary muscle is obtained most for each observer, the ciliary muscle relaxation effect is obtained most for each observer. Binocular separation images 102 and 103 can be seen. Moreover, the parallax amount of the binocular separated images 102 and 103 where the relaxation effect of the ciliary muscle is exhibited most is changed by the recovery or deterioration of the visual function of the observer. On the other hand, if the binocular separation images 102 and 103 that can obtain the most relaxing effect of the ciliary muscle for the observer are measured, the binocular separation image is obtained so that the relaxation effect of the ciliary muscle can be obtained most for the observer. 102 and 103 can be updated and viewed.

  Furthermore, as shown in FIG. 8, by using different patterns for the binocular separation images 102 and 103, when the infant uses a ciliary muscle relaxation device, both near the parallax amount suitable for the infant. The design of the eye separation images 102 and 103 can be changed every day, so that the examination can be performed without getting tired, and the concentration on the examination can be maintained.

  In FIG. 9, as another ciliary muscle relaxation device, the binocular separated image is changed so that the viewing angle for continuously viewing the binocular separated images 102 and 103 is changed within a range from 2000 seconds to 3000 seconds. A configuration including image operation units 4 and 5 for changing 102 and 103 is shown. The ciliary muscle relaxation device can set the binocular separated images 102 and 103 having a specific parallax amount by operating the image operation units 4 and 5.

  Specifically, the image operation units 4 and 5 operate the image operation units 4 and 5 so that the positional relationship between the left-eye image 102 and the right-eye image 103 as shown in FIG. The left-eye image 102 ′ can be moved as shown in FIG. 9B, and the left-eye image 102 ″ can be continuously moved as shown in FIG. 9C. Thereby, the positional relationship between the left-eye image 102 and the right-eye image 103 is changed.

  As shown in FIG. 9D, the image operation units 4 and 5 include a viewing angle presentation unit 4 that presents viewing angles necessary for viewing the binocular separated images 102 and 103 to the operator (observer), and binocular The operation unit 5 changes the viewing angle necessary to view the separated images 102 and 103. The operation unit 5 can slide the left-eye image 102 within a predetermined movable width W. The viewing angle presentation unit 4 has scales 4a and 4b on which the left end of the viewing angle presentation unit 4 shows a viewing angle of 2000 seconds and the right end of the viewing angle presentation unit 4 shows a viewing angle of 3000 seconds.

  Then, the operator (observer) slides the operation unit 5 while viewing the current amount of parallax from the scale 5 a of the operation unit 5 and the scales 4 a and 4 b of the viewing angle presentation unit 4. Accordingly, the binocular separated images 102 and 103 can be viewed at a desired viewing angle by arbitrarily setting the positional relationship between the left-eye image 102 and the right-eye image 103.

  According to such a ciliary muscle relaxation device, the positional relationship between the left-eye image 102 and the right-eye image 103 within a range in which the observer's ciliary muscle can be relaxed for 2000 seconds to 3000 seconds. The amount of parallax based on can be continuously changed. Therefore, according to this ciliary muscle relaxation device, it is possible to continuously select a viewing angle at which the observer can obtain the most effective ciliary muscle relaxation effect.

  Further, according to the ciliary muscle relaxing device, the binocular separated images 102 and 103 are viewed only at a single viewing angle of 2000 seconds to 3000 seconds with the ciliary muscle relaxing device shown in FIGS. 7 and 8, the binocular muscle relaxing apparatus shown in FIGS. 7 and 8 could not see the binocular separated images 102 and 103 with the viewing angle changed stepwise from 2000 seconds to 3000 seconds. On the other hand, according to the ciliary muscle relaxation device shown in FIG. 9, the positional relationship between the left-eye image 102 and the right-eye image 103 is continuously changed to be in the range of 2000 seconds to 3000 seconds. The binocular separated images 102 and 103 can be viewed by continuously changing the viewing angle.

  Since this ciliary muscle relaxation device moves the binocular separated images 102 and 103 within a fine range of viewing angles of 2000 seconds to 3000 seconds, depending on the operator (observer), the viewing angle presentation unit 4 may be moved between both ends. There is a possibility that the distance to move the operation unit 5 is shortened. Therefore, it is desirable to provide a function for converting a large operation on the operation unit 5 into a small movement of the binocular separated images 102 and 103.

  Specifically, as shown in FIG. 11, a mechanism for converting the rotation operation of the operator (observer) within a predetermined range W into a slide operation of the left-eye image 102 is provided. The operation unit 5 of the ciliary muscle relaxation device has a slide shaft 5a connected to the left-eye image 102 and a rotation lever 5c that is rotated around a fulcrum 5b. The presenting unit 1 is provided with a guide groove 6 that serves as a restriction for rotating the rotary lever 5c. The guide groove 6 is connected to the rotary lever 5c by a through shaft (not shown). Further, as shown in FIG. 10 (d), the rotary lever 5c is provided with a groove 5e and is connected to the slide shaft 5a in order to convert the rotation operation of the rotary lever 5c into a slide operation of the slide shaft 5a. A connecting shaft 5d is provided that can reciprocate in the groove 5e when the rotary lever 5c is rotated.

  With such a configuration, the ciliary muscle relaxation device converts the rotation operation of the rotation lever 5c in the A direction into a translation operation in the B direction, and slides the left-eye image 102 via the slide shaft 5a. be able to. Therefore, according to the ciliary muscle relaxation device, the left eye image 102 and the right eye image as shown in FIG. 10A are operated by operating in a range W longer than the movable width W shown in FIG. From the positional relationship with the image 103, the left-eye image 102 ′ is moved as shown in FIG. 10B, and the left-eye image 102 ″ is continuously moved as shown in FIG. 10C. be able to.

  Next, in the ciliary muscle relaxation device described above, a configuration in which the parallax amount of the binocular separated images 102 and 103 is changed according to the amount of eye position deviation of the observer will be described with reference to FIG. 11 shows a configuration in which the left-eye image 102 is slid by operating the operation unit 5 as shown in FIG. 9, but the rotation operation is performed by sliding the left-eye image 102 as shown in FIG. You may employ | adopt the structure converted into operation | movement.

  In this ciliary muscle relaxation device, the image operation units 4 and 5 change the amount of parallax between the binocular separated images 102 and 103 according to the amount of eye misalignment of the observer, and the observer observes the binocular separated image 102. , 103 is set to any viewing angle within a range from 2000 seconds to 3000 seconds. Thus, the ciliary muscle relaxation device reflects the amount of eye misalignment in the parallax amount of the binocular separated images 102 and 103, and recognizes the parallax amount of the binocular separated images 102 and 103 by the observer's visual function. Reduce the difference.

  The observer's eye misalignment refers to a misalignment when different images are presented to the left eye and the right eye, and an operation of superimposing the images at the center position is performed. In a normal case where there is no misalignment, different images on the left and right can be superimposed at the center position. If there is an abnormal eye position, it is recognized that the person has overlapped at the center position, but the left and right images do not actually overlap at the center position, and the distance between the left and right images (position shift) Will occur. Then, this positional shift is an observer's eye position shift, and if there is the eye position shift, individual differences occur in recognition of the parallax amount between the binocular separated images 102 and 103.

  Therefore, the ciliary muscle relaxation device includes a correction mechanism 7 that adds the amount of eye misalignment of the observer to the amount of parallax between the binocular separated images 102 and 103. Specifically, as shown in FIG. 11 (d), the correction mechanism 7 is provided with a guide groove 7 a in the presentation unit 1, and the penetrating shaft 7 b is connected to the operation unit 5 with respect to the guide groove 7 a. To do. In addition, when the operation unit 5 is slid along the guide groove 7a, the correction mechanism 7 has an instruction arrow 7c for correcting the support positions of the scales 4a and 4b of the viewing angle presentation unit 4 with respect to the position of the operation unit 5. It is attached. The instruction arrow 7c slides and moves together with the slide operation of the operation unit 5. The difference in the sliding direction between the position of the operation unit 5 with respect to the viewing angle presentation unit 4 and the position of the correction mechanism 7 is the amount of eye position deviation of the observer. Therefore, the positions of the operation unit 5 and the pointing arrow 7c of the correction mechanism 7 are adjusted according to the amount of eye position deviation of the observer. Although the correction mechanism 7 shown in FIG. 11D is added to the above-described viewing angle presentation unit 4 and the operation unit 5 (image operation units 4 and 5), it is described separately. It functions as image operation units 4, 5, 7 configured integrally with the presentation unit 4 and the operation unit 5.

  Therefore, according to the ciliary muscle relaxation device, even when the observer has a misalignment, the operation unit 5 and the instruction arrow 7c of the correction mechanism 7 indicate the amount of misalignment of each observer. The distance can be adjusted, and as shown in FIGS. 11A to 11C, the binocular separated images 102 and 103 can be viewed at a viewing angle substantially between 2000 seconds and 3000 seconds.

  Further, the ciliary muscle relaxation device to which the present invention is applied is a device in which the viewer draws the binocular separation images 102 and 103 on the presentation unit 1 such as a sheet of paper at a predetermined viewing angle. 12, the image of the binocular separated images 102 and 103 separated by linearly polarized light or circularly polarized light may be displayed on the flat screen 30 coated with silver.

  In the configuration of FIG. 12, in order to display the images of the binocular separated images 102 and 103 on the flat screen 30, the left eye is applied from the image control device 20 to the two projectors 40 </ b> R and 40 </ b> L corresponding to the left and right eyes of the observer. Video signal and right-eye video signal are supplied. The projectors 40R and 40L project left-eye video light and right-eye video light onto the flat screen 30, respectively.

  When such a configuration is adopted, an observer wearing polarized glasses (not shown) needs to have a predetermined viewpoint position with respect to the flat screen 30. Further, when image lights having different polarization directions are emitted from the projectors 40R and 40L, filters having different polarization directions are attached to the exits of the projectors 40R and 40L. On the other hand, the filter glasses 2 are provided with filters having different polarization directions on the left and right.

  The video control device 20 includes an interface 21 connected to the projectors 40R and 40L, a display control unit 22, a video storage unit 23 including a hard disk device, and an operation unit 24.

  The video storage unit 23 stores binocular separated images 102 and 103 having various patterns such as the above-described rhombus, circle, and face. The video storage unit 23 may store the binocular separated images 102 and 103 in various color combinations. However, when the display control unit 22 performs color processing on the binocular separated images 102 and 103. Do not need to remember.

  The operation unit 24 is operated when adjusting the binocular separated images 102 and 103 displayed on the flat screen 30 in the same manner as when the operator (observer) operates the operation unit 5 as described above. . The operation unit 24 may be a keyboard, a pointing device, or the like, but may be similar to the slide mechanism shown in FIG. 9, or may be a rotary lever-like one shown in FIG. .

  The display control unit 22 controls the binocular separated images 102 and 103 stored in the video storage unit 23 and outputs them to the projectors 40R and 40L via the interface 21. The display control unit 22 adjusts the interval between the binocular separated images 102 and 103 as described above, and the operation for adjusting the viewing angle for the observer to view the binocular separated images 102 and 103 is performed on the operation unit 24. When it is made, a video processing process for changing the interval between the binocular separated images 102 and 103 is performed. At this time, the display control unit 22 sets the viewing angle of the binocular separated images 102 and 103 so that the viewing angle when viewing the binocular separated images 102 and 103 from the viewpoint position of a predetermined observer is between 2000 seconds and 3000 seconds. Adjust the amount of parallax. In this way, the images in which the parallax amounts of the binocular separated images 102 and 103 are adjusted can be projected by the projectors 40R and 40L, and the binocular separated images 102 and 103 can be displayed on the flat screen 30.

  Note that the present invention is not limited to such a configuration, and any configuration may be adopted as long as the stereoscopic video presentation system can present the binocular separated images 102 and 103. Current technologies for binocular separation include anaglyph, polarization, and time division, and video display includes HMD (head mounted display), display, and projection. Any technique can be used.
