Description

Technical Field

[0001] The utility model relates to the field of optical imaging, in particular to a surround imaging device. Background Art

[0002] Nowadays, people have an increasingly strong demand for immersive visual experience. For example, the current spherical screen display and annular (or surround) screen display can bring a strong visual immersion experience to the people surrounded. However, these traditional technologies are currently limited by the size of the screen and the size of the venue space, and the cost is very high. In addition, these traditional surround screens actually create an opaque surround-wrapped three-dimensional space, which cannot display transparent images while displaying surround images (that is, through transparent images, you can see real objects in reality). The images displayed by these traditional image surround technologies cannot be integrated with the real scene behind the screen. Since the real objects behind the images cannot be seen and there is no real reference to the background, the depth, three-dimensionality and immersion of the images are weakened. In addition, virtual three-dimensional images cannot be displayed from the front and back at the same time, so they have limitations. Utility Model Content

[0016] According to the optical reflection principle, the reflection imaging analysis of the present invention is as follows: As Figures 1 to 12As shown, the first reflector 1 and the second reflector 2 are used as reflective carriers, and the reflectors shown can be plane mirrors or curved mirrors. The light emitted from the first screen 3 is mutually (back and forth) reflected between the first reflector 1 and the second reflector 2 to form (generate) virtual image set A and virtual image set B. Virtual image set A={A1, A2,…,A n}, each element in the set A represents a reflected virtual image, and there are n elements in the set A (that is, the number of virtual images is n), wherein the virtual image A1 is the first virtual image generated by the first screen 3 using the first reflector 1 as a reflection carrier, and the virtual image A n refers to the nth virtual image in the virtual image set A, A n is the last virtual image generated in the virtual image set A. Similarly, the virtual image set B={B1,B2,…,B n}; wherein the virtual image B1 refers to the first virtual image generated by the first screen 3 with the second reflector 2 as the reflection carrier, and the virtual image B n refers to the nth virtual image in the virtual image set B, virtual image B n It is the last virtual image generated in the virtual image set B. The virtual images in the virtual image set of the utility model are arranged in the order of the time when the corresponding virtual images are generated, that is, virtual image A1 and virtual image B1 are the first virtual images generated correspondingly, that is, virtual image A n and virtual image B n is the last virtual image generated in the corresponding virtual image set. According to the optical reflection imaging law, the virtual image A n-1 The corresponding virtual image B is generated by using the second reflector 2 as a reflector to reflect at the corresponding position n , for example, when n=12, the virtual image A 11 = virtual image A 12-1 , that is, A 11 The second reflector 2 is used as a reflector to generate a corresponding virtual image B at a corresponding position. 11 , where the virtual image A 12 and virtual image B 12 is the corresponding virtual image generated at last, the virtual image A n-1 refers to the n-1th virtual image in the set A (i.e., the previous virtual image of the nth virtual image). Similarly, the virtual image B n-1 By using the reflector 1 as a reflection carrier, a corresponding virtual image A is generated at a corresponding position. n , for example, when n=12, the virtual image B 11 The first reflector 1 is used as a reflective carrier to generate a corresponding virtual image A at a corresponding position. 12 , where the virtual image B 12 and virtual image A 12 It is the corresponding virtual image generated at last. The virtual image Bn-1 It refers to the n-1th virtual image in the set B (i.e., the previous virtual image of the nth virtual image).

[0017] like Figure 1 , Figure 8 and Fig. 9 As shown, the virtual image set F={F1, F2, F3…,F m}, m is a natural number, F m is the mth virtual image, the virtual images in the virtual image set F are virtual images corresponding to the first reflector 1, wherein the virtual image F1 corresponds to the first virtual principal optical axis 42, the virtual image F2 corresponds to the second virtual principal optical axis 43, and the virtual image F3 corresponds to the third virtual principal optical axis 44; the virtual images A2 and A3 correspond to the virtual image F1, the virtual images A4 and A5 correspond to the virtual image F2, the virtual images A6 and A7 correspond to the virtual image F3, and so on; the set of angles formed by the principal optical axes (or corresponding normals) of the virtual images in the virtual image set F and the second principal optical axis 34 (or the second normal 12) is γ={γ1,γ2,…,γ m}, where m is a natural number, angle γ1 = α + 2α, angle γ2 = α + 4α, angle γ3 = α + 6α, angle γ4 = α + 8α, γ5 = α + 10α, that is, when the value of the angle α increases, the angle γ 1、 Angle γ 2、 Angle γ 3、 The values ​​of angle γ4 and angle γ5 increase, and so on; therefore, the set γ is an arithmetic progression, which increases monotonically. According to the law of optical imaging, it can be concluded that the virtual images in the virtual image set A are generated in chronological order and arranged in a circle. Among them, virtual image A2 and virtual image A3 are a virtual image group, virtual image A4 and virtual image A5 are a virtual image group, virtual image A6 and virtual image A7 are a virtual image group, and so on. Therefore, the direction of the normal vector corresponding to each virtual image group in the set A is deflected by an angle of 2α in the corresponding direction, so that the virtual images can be arranged in a circle around the corresponding axis, that is, the virtual images in the virtual image set A are combined and arranged into a ring-shaped visual effect, forming a unique three-dimensional surround visual space. Similarly, the virtual images in the virtual image set B are also combined and arranged into a ring-shaped effect. For example, if Figure 1 As shown, the virtual images in set A are within a first range 21, and the virtual images in set B are within a second range 22. Through the first direction 11, the virtual images in virtual image set A can be seen to be arranged in a ring, and through the second direction 32, the virtual images in virtual image set B can be seen to be arranged in a ring. The first range 21 or the second range 22 refers to the three-dimensional space range on one side of the first tangent plane 16 or the second tangent plane 25.

[0018] In summary, the number n of virtual images formed by the first screen 3 within the first range 21 is the integer part of the quotient of 180° / α (for example, the integer part is a), or the integer part of the quotient of 180° / α (for example, the integer part is a) plus 1, which is the corresponding number n of virtual images, that is, n=a+1; for example, when the integer part of the quotient of 180° / α is a and the decimal part is 0, the corresponding number n of virtual images is n=a, and when the angle α is 15°, n=180° / 15°=12, that is, the corresponding number n of virtual images is 12, that is, virtual image A n = virtual image A 12 , at this time, the last virtual image generated in set A is a complete reflected virtual image; for another example, when the integer part of the quotient of 180° / α is a and the decimal part is not 0, the number of virtual images n=a+1, when angle α=19°, 180° / 19°=9.4736, that is, the number of corresponding virtual images n=9+1=10, virtual image A n = virtual image A 10 At this time, the last virtual image generated in the virtual image set A is a reflected virtual image that is not completely generated (displayed). Point M is a point on the virtual image A1, and point M′ is a point on the virtual image A1. n A point on the line 16, point M and point M' are two corresponding points, the distance between line segment MM' is L (that is, the distance between the first virtual image generated and the last virtual image generated), when the value of angle α is divisible by 180°, line segment MM' is parallel to the first tangent plane 16; when angle α is equal to 0°, the value of the number n of virtual images is infinite, the last virtual image cannot be determined, and the shape formed by the arrangement of its virtual images is not a ring, and the last virtual image is at infinity, that is, at this time, virtual image A1 and virtual image A n The distance L is infinite and cannot be determined. The size of the angle α is used to determine the number n of virtual images in the virtual image set A or the virtual image set B. When the angle α increases, the number n of virtual images decreases accordingly. The adjustment of the number n of virtual images can meet the convenience of adjusting the number of virtual images and meet different visual effect requirements. The visual effects include: the visual effects presented by the density of the virtual image distribution in the virtual image set A or the virtual image set B. The density refers to the density (virtual image density) of all virtual images generated in the space of the first range 21. The size of the angle α is also used to make the corresponding orientation of the first virtual image (i.e., virtual image A1) in the virtual image set A, the last virtual image (i.e., virtual image A n ) and the corresponding directions of other corresponding virtual images produce different directions, so that the corresponding virtual images produce a unique surrounding arrangement visual effect. When the value of α changes, the virtual image A1 and the virtual image A nThe corresponding orientation changes accordingly, and the corresponding orientation refers to the direction of the normal vector corresponding to the virtual image itself. Point N is a point on the surrounding axis, point P is a point on the surface of the first screen 3, and the distance of the line segment NP is W, W<200 meters; according to the law of optical reflection imaging, when the value of W is increased or decreased, the value of L also increases or decreases, and the size of the distance W is also used to control the size of the distance L; in addition, 2W>L, the size of the distance W is used to control the size of the distance L, and when the distance W increases, the distance L increases; the size of the distance W of the line segment NP is used to adjust or determine the viewing distance between the audience 19 or the audience 18 and the corresponding virtual image (for example, the virtual image in the set A and the set B), which can conveniently determine the distribution range of the virtual images in the virtual image set A and the virtual image set B to meet different visual effect requirements.

[0019] In summary, it can be concluded that if Figure 1 , Figure 8 and Fig. 9 When the first reflector 1 and the second reflector 2 are plane mirrors and / or curved mirrors, the virtual images (virtual images in the virtual image set A or the virtual image set B) generated by reflection in the present invention are all arranged and distributed in a surrounding manner.

[0020] The beneficial effect of the utility model is: to achieve real-time adjustment of the corresponding normal direction of each virtual image in the virtual image set A or the virtual image set B, and the virtual image generated by the reflection can show a transparent (similar to the traditional phantom imaging effect) or opaque, and annularly arranged stereoscopic image effect (it can also be used in combination with stereoscopic equipment and corresponding technologies to produce a more realistic stereoscopic immersive effect), and can form a semi-enclosed (or semi-enclosed) or fully enclosed (or fully enclosed) surround virtual stereoscopic image, and finally produce a surround virtual stereoscopic space, which can surround (surround) the observer in the virtual stereoscopic image, thereby giving the observer in it a strong visual immersion experience. By setting the corresponding display object (such as the first display object, 78. the second display object or 79. the third display object), the surround virtual image generated by the corresponding display object and the image displayed on the display screen can form a set of virtual and real fusion double-layer surround stereoscopic images, which has a strong visual immersion experience. By determining the size of the corresponding angle α, the number n of virtual images in the virtual image set A and the virtual image set B can be determined in real time (for example, as the angle α decreases, the number n of virtual images generated increases), and the density of the virtual images can be determined in real time or dynamically controlled, effectively achieving the appreciation and interest of the visual effect. By determining the size of the corresponding angle α and the size of the distance W, the size of the distance L can be controlled to achieve real-time control of the size of the ring formed by the virtual images in the virtual image set A and the virtual image set B, meeting the use requirements of different venues; by controlling the size of the angle α, the number of virtual images displayed on the corresponding screen can be flexibly controlled, saving the corresponding screen materials, and using fewer screens to display the effect of multiple virtual screens. Since multiple virtual image effects can be displayed, the virtual images do not occupy space, that is, a smaller space (or smaller area) can be used to display the image effect that can only be produced by a larger space (or larger area). When the reflectors are all plane mirrors, each virtual image in the virtual image set A or the virtual image set B can produce a virtual image of the same size. When the reflector includes a curved mirror, each virtual image in the virtual image set A or the virtual image set B can produce a virtual image of different sizes with a magnifying effect, which also meets the flexible use requirements of different scenes. The audience can watch the virtual stereoscopic image from the front (such as the first direction 11) and the back (such as the second direction 32) at the same time. In addition, the utility model can also observe stereoscopic images (parallax type) with the naked eye, and can also see stereoscopic images (non-parallax type) surrounding multiple layers, which can further enhance the visual immersion experience. The utility model can be widely used in immersive experience fields such as exhibitions, amusement, intelligent interaction, and metaverse.

Among all straight lines connecting any two points on the reflecting surface, the distance of line segment bd is the longest, and the distance of line segment bd is greater than 0.2W, for example, W is equal to 2 meters, and the distance of line segment bd is more than 0.4 meters; point e and point f are two points on the reflecting surface of the second reflector 2, and among all straight lines connecting any two points on the reflecting surface of the second reflector 2, the distance of line segment ef is the longest, and the distance of line segment ef is greater than 0.2W; the edge surface 80 of the reflector is brought into contact with a black substance, for example, by black coating the edge thickness portion of the glass (for example, the edge surface 80) with black paint, and the black paint is used to reduce the brightness of the edge portion of the glass and reduce the interference of reflected light to the eyes; the first screen 3 is a liquid crystal screen, for example Figure 1 According to the imaging principle of optical reflection, the virtual image set A={A1,A2,…,A n}, the virtual image set B={B1,B2,…,B n}, determine the number of virtual images in the virtual image set A and the virtual image set B n=180° / 15°=12, that is, generate 24 corresponding complete virtual images in the first range 21 and the second range 22, the virtual images generated in the first range 21 (the virtual images in the virtual image set A) are: A1, A2, A3, A4, A5, A6, A7, A8, A9, A 10 , A11 , A 12 , that is, the virtual image set A={A1,A2,…,A 12}, the virtual images generated by the second range 22 (the virtual images in the virtual image set B) are: B1, B2, B3, B4, B5, B6, B7, B8, B9, B 10 ,B 11 ,B 12 , that is, the virtual image set B={B1,B2,…,B 12},like Figure 1 As shown, according to the above reflection imaging analysis, the 24 virtual images are arranged in a surrounding manner. The first observer 6 observes along the first direction 11 and can observe the virtual images A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A111, A12, A13, A14, A15, A16, A17, A18, A19, A20, A21, A22, A23, A24, A25, A26, A27, A28, A29, A30, A31, A32, A33, A34, A35, A36, A37, A38, A39, A40, A41, A42, A43, A44, A45, A46, A47, A48, A49, A50, A51, A52, A53, A54, A55 10 , A 11 and A 12 , and can also be observed in the second direction 32, and virtual images B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B13, B14, B15, B16, B17, B18, B19, B20, B21, B22, B23, B24, B25, B26, B27, B28, B29, B3 10 , B 11 and B 12 , the 24 virtual images in the virtual image set A and the virtual image set B are seen to be distributed in a surrounding manner (arranged in a circular shape with point N as the center); in addition, the third observer 19 observes in the first direction 11, and sees part of the virtual images in the virtual image set A through the first reflector 1, such as seeing virtual images A1, A2, A3, A4, A5, and A6, and sees that these virtual images are distributed in a semi-circular manner (arranged in a semi-circular shape with point N as the center); the second observer 18 observes in the second direction 32, and can see part of the virtual images in the virtual image set B through the second reflector 2, such as seeing virtual images B1, B2, B3, B4, B5, and B6, and sees that these virtual images are distributed in a semi-circular manner (arranged in a semi-circular shape with point N as the center). Set point M and point M′, the distance between line segment MM′ is L, point M is a point on the virtual image A1, and point M′ is a point on the virtual image A1. n When a light ray emitted from a point on the first screen 3 is reflected to form a light ray, the reverse extension line of the light ray will be aligned with the virtual image A1 and the virtual image A n intersect at two points respectively, then these two points can be point M and point M′, that is, these two points are corresponding points; according to the law of optical reflection, set point M and point P are also two corresponding points, that is, the distance of line segment NP is equal to the distance of line segment NM, set the distance from point P to the first tangent plane 16 to K, according to the Pythagorean theorem, , Right now, . The first observer 6, the second observer 18 and the third observer 19 can all watch the virtual images with a surround arrangement effect with a strong sense of immersion. Since the first reflector 1 and the second reflector 2 are both translucent, the observers can see that the virtual images in the virtual image set A and the virtual images in the virtual image set B are transparent, thereby achieving the effect of virtual-real fusion of transparent virtual images with the surrounding real objects on the site or the real objects in the front, back, left, right, up and down directions, that is, by using the real objects in the front, back, left, right, up and down directions as reference objects, a strange and strong surround fusion of virtual and real immersion experience is generated. This kind of effect has not been produced before the present utility model. This embodiment uses only one display screen to generate multiple identical virtual display screens, expands the space for image display, and finally produces a surround-wrapped virtual three-dimensional space. While improving the sense of immersion and mystery, it saves costs.

Wherein the virtual image set C={C1,C2,…,C r}, virtual image set D = {D1, D2, ..., D r}, wherein r=12. The first exhibit 77, the second exhibit 78 and the third exhibit 79 are as follows Figure 3The three exhibits are illuminated by light. According to the above light reflection analysis, the first exhibit 77, the second exhibit 78 and the third exhibit 79 respectively generate three corresponding virtual image sets, which are virtual image sets H={H1, H2, …, H 12}, virtual image set E={E1,E2,…,E 12}, virtual image set Q = {Q1, Q2}, the virtual images in the three virtual image sets are arranged in a surrounding manner, and these virtual images can also correspondingly display the appearance effects of the first exhibit 77, the second exhibit 78 and the third exhibit 79 at different angles; the virtual images in the virtual image set H, the virtual image set E and the virtual image set Q (forming the second layer of images), and the virtual images in the virtual image set A and the virtual image set C (forming the first layer of images) together form a group of multi-layer surround virtual-real fusion stereoscopic images with front and back distances, and finally produce a surround-wrapped virtual three-dimensional space, thereby producing a unique visual immersion experience.

According to Example 1, the virtual image can also form a surround effect.

[0050] The following is embodiment 7 of the present utility model. Fig. 9 and Fig.15 As shown, on the basis of Example 1, the plane mirrors of the first reflector 1 and the second reflector 2 are replaced with curved mirrors, for example, the first reflector 1 is replaced with a cylindrical mirror (such as Fig.10As shown), the second reflector 2 is replaced with a concave mirror, and the corresponding reflecting surface of the curved mirror is coated with a metal film; the first principal optical axis 33 of the reflector 1 (i.e., the cylindrical mirror) forms an angle α with the second principal optical axis 34 of the curved mirror (concave mirror), α=15°, the object distance between the first screen 3 and the curved mirror is u=0.5 meters, the focal length of the curved mirror is u=5 meters, the first principal optical axis 33 can be the principal optical axis passing through the center of the first reflector 1, point b and point d are two points on the reflecting surface of the first reflector 1, and among all straight lines connecting any two points on the reflecting surface of the first reflector 1, the distance of line segment bd is the longest, and the distance of line segment bd is greater than 0.2W; point e and point f are two points on the reflecting surface of the second reflector 2, and among all straight lines connecting any two points on the reflecting surface of the second reflector 2, the distance of line segment ef is the longest, and the distance of line segment ef is greater than 0.2W.

[0052] The following is embodiment 9 of the present utility model. Fig.11 On the basis of Example 1, a fifth reflector 45 is added, the object 4 is arranged between the first reflector 1, the second reflector 2 and the fifth reflector 45, the object 4 (for example, a display object) is illuminated by light, and the fifth reflector 45 is a transparent reflector or an opaque reflector. Fig.11According to the law of optical reflection, the real object 4 can form a plurality of first reflected virtual images 47 arranged in a surrounding manner through mutual reflection of the first reflector 1, the second reflector 2 and the fifth reflector 45, thereby forming a unique visual effect.

According to the principle of optical reflection, the third screen 52 forms a virtual image set G={G1, G2, G3, G4, G5} through the reflection of the reflector 1 and the reflector 2. The virtual images in the virtual image set G will be superimposed in front of the virtual images in the virtual image set A and the virtual image set C to form two layers of virtual images. When the third observer 19 observes according to the first direction 11, he will see the two layers of virtual images with front and back layers at the same time, that is, the first layer of images refers to the virtual images in the virtual image set A and the virtual images in the virtual image set C, and the second layer of images refers to the virtual images in the virtual image set G. The two layers of virtual images seen together form a surrounding double-layer three-dimensional space, thereby enabling the observer to have a strong sense of three-dimensional immersion. According to the principle of optical imaging, if the image displayed on the third screen 52 (i.e., the second layer of image) includes images with lower brightness and higher brightness, then the portion with lower brightness will be penetrated by the portion with higher brightness of the first layer of image, i.e., the portion with lower brightness on the second layer of image will not be visible, thereby achieving the superposition of images in the same line of sight, generating a three-dimensional sense with front and back layers, and presenting an extremely unique three-dimensional immersive effect of fusion of virtual and real.

The positive virtual image refers to the image generated by the original image through specular reflection and having the same left and right direction as the original image; the reverse virtual image refers to the image generated by the original image through specular reflection and being symmetrical to the original image. Points b and d are two points on the reflecting surface of the first reflector 1, and among all the straight lines connecting any two points on the reflecting surface of the first reflector 1, the distance of the line segment bd is the longest; points g and h are two points on the reflecting surface of the third reflector 13, and among all the straight lines connecting any two points on the reflecting surface of the third reflector 13, the distance of the line segment gh is the longest.

[0058] The first reflector 1 and the second reflector 2 are used to reflect the first screen 3 into corresponding virtual images at corresponding positions, and the third reflector 13 and the fourth reflector 14 are used to reflect the second screen 15 into corresponding virtual images at corresponding positions; that is, the first screen 3 generates the virtual images in the virtual image set A through the first reflector 1, the first screen 3 generates the virtual images in the virtual image set B through the second reflector 2, the second screen 15 generates the virtual images in the virtual image set C through the third reflector 13, and the second screen 15 generates the virtual images in the virtual image set D through the fourth reflector 14; the virtual image set A = {A1, A2, …, A n}, the virtual image set B = {B1, B2, …, B n}, the virtual image set C = {C1, C2, …, C n}, the virtual image set D = {D1, D2, …, D n}, where n is a natural number, 1 < n < 90, and the n refers to the number of virtual images in the virtual image set A, the virtual image set B, the virtual image set C, and the virtual image set D. The virtual image An is the nth virtual image in the virtual image set A. The virtual image B n is the nth virtual image in the virtual image set B, the virtual image C n is the nth virtual image in the virtual image set C, the virtual image D n is the nth virtual image in the virtual image set D; the virtual image A n is the last virtual image generated in the virtual image set A, and the virtual image B n is the last virtual image generated in the virtual image set B. The virtual image C n is the last virtual image generated in the virtual image set C. The virtual image D n It is the last virtual image generated in the virtual image set D.

[0059] The first screen 3 and the second screen 15 are respectively configured to play the corresponding left-eye parallax images at the same time. According to the parallax stereoscopic imaging principle, within the third range 62, at least one virtual image in the virtual image set A is matched with at least one virtual image in the virtual image set C in terms of parallax position, for example, the parallax image of virtual image A5 (left-eye parallax image) is matched with the parallax image of virtual image C6 (right-eye parallax image); or the parallax image of virtual image C5 (right-eye parallax image) is matched with the parallax image of virtual image A6 (left-eye parallax image). Match the position of at least one virtual image in the virtual image set A with at least one virtual image in the virtual image set C in terms of parallax, set at least one virtual image in the virtual image set A as virtual image J, and set at least one virtual image in the virtual image set C as virtual image K. The virtual image J may include the virtual images in the virtual image set A within the third range 62, that is, virtual image A4 and / or virtual image A5 and / or virtual image A6 and / or virtual image A7; the virtual image K may include the virtual images in the virtual image set C within the third range 62, that is, virtual image C4 and / or virtual image C5 and / or virtual image C6 and / or virtual image C7.

[0060] The audience's eyes are placed close to the second reflector 2 and the fourth reflector 14 (the closer to the corresponding reflectors, the larger the range of the corresponding virtual image seen), and the left eye and the right eye are respectively located on both sides of the fourth plane 64 (the fourth plane 64 is the angle bisector of the angle V), and the fourth plane 64 is placed as close as possible to the middle position between the two eyes, facing the first reflector 1 and the third reflector 13, and viewing the virtual image in front. When the audience watches in the first direction 11, facing the first reflector 1 and the third reflector 13, that is, the left eye 60 can only see the virtual images in the virtual image set A but not the virtual images in the virtual image set B, and the right eye can only see the virtual images in the virtual image set B but not the virtual images in the virtual image set A, that is, the left eye 60 can see the corresponding virtual images in the third range 63 through the first reflector 1, and can see A1, A2A3, A4A5, A6A7; the right eye 61 can see the corresponding virtual images in the fourth range 67 through the third reflector 13, for example, see C1, C2C3, C4C5, C6C7. According to the parallax stereoscopic imaging principle, the audience can see the corresponding stereoscopic image by synthesizing the virtual image A and the virtual image B in the third range 62 at the same time, so the audience can see the stereoscopic image with a stereoscopic effect through the reflector 1 and the reflector 13. Make the virtual image A5 contain the corresponding left eye parallax image, and make the virtual image C6 contain the corresponding right eye parallax image. At this time, the eyes can see a stereoscopic image synthesized by the virtual image A5 and the virtual image C6 (actually synthesized by the corresponding left eye and right eye parallax images). At this time, since the virtual image A5 is the reverse image of the first parallax image displayed on the first screen, and the virtual image C6 is the forward image of the second parallax image displayed on the second screen, the first parallax image or the second parallax image can be processed by the video synthesis software in a mirror symmetric manner and then played and displayed to obtain a correctly synthesized stereoscopic image; with the above processing, make the virtual image C5 contain the corresponding right eye parallax image, and the virtual image A6 contain the corresponding left eye parallax image. At this time, the eyes can also see a stereoscopic image synthesized by the virtual image C5 and the virtual image A6. Similarly, when the audience watches the second reflector 2 and the fourth reflector 14 in the second direction 32, the audience can see the image with a stereoscopic effect through the second reflector 2 and the fourth reflector 14. In addition, an anti-peep film can be set on the display surfaces of the first screen 3 and the second screen 15.
