Description

Technical Field

[0001] This invention relates to an imaging device, and more particularly to a stereoscopic imaging device. Background Technology

[0002] Parallax barriers and lenticular lenses are common naked-eye stereoscopic imaging techniques. Although they can generate different stereoscopic or dynamic stereoscopic images through displays such as liquid crystal displays, they suffer from poor resolution. Furthermore, while projecting light from a light source onto a high-resolution imaging plate can generate high-resolution levitation stereoscopic images, only a single image corresponding to the image data on the imaging plate can be generated. Summary of the Invention

[0003] This invention relates to a stereoscopic imaging device capable of displaying different high-resolution stereoscopic images or dynamic stereoscopic images.

[0004] According to one embodiment of the present invention, a stereoscopic imaging device includes a light source, a control mechanism, and a light-transmitting sheet. The light-transmitting sheet is coupled to the control mechanism and disposed on one side of the light source. The light-transmitting sheet includes a first pattern area and a second pattern area, and the control mechanism is used to control the light-transmitting sheet to generate displacement, so that light from the light source is received by the first pattern area or converted to light from the light source being received by the second pattern area, thereby displaying different stereoscopic images.

[0005] According to another embodiment of the present invention, a stereoscopic imaging device includes a light source, a control mechanism, a light-transmitting plate, and a light-shielding plate. The light-transmitting plate is coupled to the control mechanism and disposed on one side of the light source. The light-transmitting plate includes a first pattern area and a second pattern area, and the light-shielding plate is disposed between the light source and the light-transmitting plate. The light-transmitting plate or the light-shielding plate is coupled to the control mechanism and is adapted to be displaced under the control of the control mechanism, so that the first pattern area receives light from the light source and the second pattern area is blocked by the light-shielding plate, or the light-transmitting plate is switched to the second pattern area receiving light from the light source and the first pattern area being blocked by the light-shielding plate, thereby displaying different stereoscopic images.

[0014] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0015] Figure 1 This is a schematic diagram of the imaging conversion of a stereoscopic imaging device according to an embodiment of the present invention. Please refer to... Figure 1 In this embodiment, the stereoscopic imaging device 100 includes a light source 110, a light-transmitting sheet 120, and a control mechanism 20. Specifically, the light-transmitting sheet 120 is disposed on one side of the light source 110 and located in the optical path of the light ray 111 emitted by the light source 110. The light-transmitting sheet 120 is, for example, an imaging sheet, and includes at least a linearly arranged first pattern area 121 and a second pattern area 122.

[0016] For example, the first pattern area 121 has image data corresponding to the first holographic image 121a, and the second pattern area 122 has image data corresponding to the second holographic image 122a. On the other hand, the image data can be formed on the light-transmitting film 120 through printing, photolithography, or other suitable methods, that is, the light field information of the object to be imaged (such as spatial position coordinates, orientation angle, and intensity) is recorded on the light-transmitting film 120. Furthermore, the holographic image of the object to be imaged cannot be directly seen through the naked-eye light-transmitting film 120; it requires a light source to reconstruct the light field information recorded on the light-transmitting film 120, restoring the characteristics and direction of the reflected light entering the viewer's eyes, in order to see the holographic image. This allows the viewer to produce the same visual effect as observing a real object when viewing the reconstructed holographic image from various angles.

[0017] The light-transmitting sheet 120 is coupled to the control mechanism 20, which controls the light-transmitting sheet 120 to produce a linear displacement relative to the light source 110, for example, sliding along the horizontal direction. When the first pattern area 121 is aligned with the light source 110, the second pattern area 122 is misaligned with the light source 110, so that the first pattern area 121 receives light 111 from the light source 110, thereby displaying a first levitation stereoscopic image 121a with high resolution above or to one side of the light-transmitting sheet 120. When the control mechanism 20 controls the light-transmitting sheet 120 to move and align the second pattern area 122 with the light source 110, the first pattern area 121 is misaligned with the light source 110, so that the second pattern area 122 receives light 111 from the light source 110, thereby displaying a second levitation stereoscopic image 122a with high resolution above or to one side of the light-transmitting sheet 120. However, for the sake of simplifying the drawings and aiding understanding, the levitation stereoscopic images of each embodiment are drawn in a simplified manner, but in practical applications, there can be more complex patterns that can be used with stereoscopic imaging devices.

[0018] For example, the light-transmitting sheet 120 may contain two or more patterned areas, which are linearly arranged on the light-transmitting sheet 120. When any patterned area receives light 111 from the light source 110, a corresponding holographic image is displayed above or to one side of the light-transmitting sheet 120. In one example, these holographic images may be different stereoscopic images, each displaying different image content. In another example, these holographic images may be similar stereoscopic images, but in different states; through the linear displacement generated by the light-transmitting sheet 120, these stereoscopic images can be continuously transformed, thereby achieving the display of dynamic stereoscopic images.

[0019] Figure 2 This is a schematic diagram of the imaging conversion of a stereoscopic imaging device according to another embodiment of the present invention. Please refer to... Figure 2 In this embodiment, the stereoscopic imaging device 100A includes a light source 110, a light-transmitting sheet 120a, and a control mechanism 21. Specifically, the light-transmitting sheet 120a is disposed on one side of the light source 110 and located in the optical path of the light ray 111 emitted by the light source 110. The light-transmitting sheet 120a can be an imaging sheet and includes at least a first pattern area 121, a second pattern area 122, a third pattern area 123, and a fourth pattern area 124.

[0020] For example, the first pattern area 121 has image data corresponding to the first holographic image 121a, and the second pattern area 122 has image data corresponding to the second holographic image 122a. In addition, the third pattern area 123 has image data corresponding to the third holographic image 123a, and the fourth pattern area 124 has image data corresponding to the fourth holographic image 124a.

[0021] In this embodiment, the first pattern area 121, the second pattern area 122, the third pattern area 123, and the fourth pattern area 124 can be arranged in a matrix on the light-transmitting sheet 120a, and the light-transmitting sheet 120a is coupled to the control mechanism 21 so that the control mechanism 21 controls the light-transmitting sheet 120a to generate a rotational displacement relative to the light source 110, for example, rotating about a vertical axis relative to the light source 110. When the first pattern area 121 is aligned with the light source 110, the second pattern area 122, the third pattern area 123, and the fourth pattern area 124 are misaligned with the light source 110 so that the first pattern area 121 receives the light 111 from the light source 110, thereby displaying a first levitation stereoscopic image 121a with high resolution above or to one side of the light-transmitting sheet 120a.

[0022] When the control mechanism 21 controls the light-transmitting sheet 120a to rotate relative to the light source 110 (e.g., rotate 90 degrees counterclockwise) and aligns the second pattern area 122 with the light source 110, the first pattern area 121, the third pattern area 123, and the fourth pattern area 124 are misaligned with the light source 110 so that the second pattern area 122 receives the light 111 from the light source 110, thereby displaying a second levitation stereoscopic image 122a with high resolution above or to one side of the light-transmitting sheet 120a.

[0023] When the control mechanism 21 controls the light-transmitting sheet 120a to rotate relative to the light source 110 (e.g., rotate 90 degrees counterclockwise) and aligns the third pattern area 123 with the light source 110, the first pattern area 121, the second pattern area 122, and the fourth pattern area 124 are misaligned with the light source 110 so that the third pattern area 123 receives the light 111 from the light source 110, thereby displaying a high-resolution third levitation stereoscopic image 123a above or to one side of the light-transmitting sheet 120a.

[0024] When the control mechanism 21 controls the light-transmitting sheet 120a to rotate relative to the light source 110 (e.g., rotate 90 degrees counterclockwise) and aligns the fourth pattern area 124 with the light source 110, the first pattern area 121, the second pattern area 122, and the third pattern area 123 are misaligned with the light source 110 so that the fourth pattern area 124 receives the light 111 from the light source 110, thereby displaying a high-resolution fourth levitation stereoscopic image 124a above or to one side of the light-transmitting sheet 120a.

[0025] It should be noted that the control mechanism 21 also controls the light-transmitting sheet 120a to rotate clockwise relative to the light source 110, and sequentially displays the first floating stereoscopic image 121a, the fourth floating stereoscopic image 124a, the third floating stereoscopic image 123a and the second floating stereoscopic image 122a.

[0026] For example, the light-transmitting sheet 120a may contain four patterned areas arranged in a matrix, more patterned areas arranged in a matrix, or multiple patterned areas arranged in a ring. When any patterned area receives light 111 from the light source 110, a corresponding holographic image is displayed above or to one side of the light-transmitting sheet 120a. In one example, these holographic images may be different stereoscopic images, each displaying different image content. In another example, these holographic images may be similar stereoscopic images, but in different states; through the rotational displacement generated by the light-transmitting sheet 120a, these stereoscopic images can be continuously transformed, thereby achieving the display of dynamic stereoscopic images.

[0027] Depending on the imaging requirements, the control mechanism 21 can flexibly control the light-transmitting sheet 120a to rotate in a counterclockwise or clockwise direction, and is not limited to continuous rotation in a single direction. In addition, the light-transmitting sheet 120a can also adopt a horizontal movement mechanism (e.g., forward, backward, left, and right movement) to achieve image conversion.

[0028] Figure 3 This is a schematic diagram of the imaging conversion of a stereoscopic imaging device according to another embodiment of the present invention. Please refer to... Figure 3 In this embodiment, the stereoscopic imaging device 100B includes a light source 110, a light-transmitting sheet 120, a light-shielding sheet 130, and a control mechanism 20. Specifically, the light-transmitting sheet 120 is disposed on one side of the light source 110 and is located in the optical path of the light ray 111 emitted by the light source 110. The light-transmitting sheet 120 may be an imaging sheet and includes at least a linearly arranged first pattern area 121 and a second pattern area 122.

[0029] For example, the first pattern area 121 has image data corresponding to the first holographic image 121a, and the second pattern area 122 has image data corresponding to the second holographic image 122a.

[0030] A light-shielding plate 130 is disposed between the light source 110 and the light-transmitting plate 120 and coupled to the control mechanism 20. Specifically, the light-shielding plate 130, the light source 110, and the light-transmitting plate 120 can be relatively displaced. For example, the positions of the light-transmitting plate 120 and the light source 110 remain fixed, and the control mechanism 20 controls the light-shielding plate 130 to produce a linear displacement between the light source 110 and the light-transmitting plate 120, for example, moving horizontally. Based on the sliding of the light-shielding plate 130 between the light source 110 and the light-transmitting plate 120, in one state, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the first pattern area 121. Conversely, the other portion of the light 111 is blocked by the light-shielding plate 130 and cannot be projected onto the second pattern area 122; that is, the light-shielding plate 130 blocks the second pattern area 122. In another state, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the second pattern area 122. Conversely, other parts of the light 111 are blocked by the light shield 130 and cannot be projected onto the first pattern area 121, that is, the light shield 130 blocks the first pattern area 121.

[0031] In detail, the light-blocking plate 130 may include a light-transmitting area 131 and a light-blocking area 132. A portion of the light 111 can pass through the light-transmitting area 131 and be projected onto the light-transmitting plate 120. The remaining portion of the light 111 is blocked by the light-blocking area 132 and cannot be projected onto the light-transmitting plate 120. When the light-transmitting area 131 is located in the first pattern area 121, the light-blocking area 132 is located in the second pattern area 122, so that the first pattern area 121 receives the light 111 from the light source 110, and the light-blocking plate 130 blocks the second pattern area 122, thereby displaying a first levitation stereoscopic image 121a with high resolution above or to one side of the light-transmitting plate 120.

[0032] When the control mechanism 20 controls the light-shielding plate 130 to move between the light source 110 and the light-transmitting plate 120 and the light-transmitting area 131 is positioned in the second pattern area 122, the light-shielding area 132 is positioned in the first pattern area 121 so that the light 111 from the light source 110 is received by the second pattern area 122 and the first pattern area 121 is blocked by the light-shielding plate 130, thereby displaying a second levitation stereoscopic image 122a with high resolution above or to one side of the light-transmitting plate 120.

[0033] For example, the light-transmitting sheet 120 may include two or more patterned areas, which are arranged linearly on the light-transmitting sheet 120, for example. When any patterned area receives light 111 from the light source 110, a corresponding holographic image is displayed above or to one side of the light-transmitting sheet 120. In one example, these holographic images may be different stereoscopic images, each displaying different image content. In another example, these holographic images may be similar stereoscopic images, but in different states; through the displacement produced by the light-blocking sheet 130, these stereoscopic images can be continuously switched, thereby achieving the display of dynamic stereoscopic images.

[0034] In other design modifications, the positions of the light-shielding plate 130 and the light source 110 can remain unchanged. By making the light-transmitting plate 120 linearly displaced relative to the light-shielding plate 130, different display effects of stereoscopic images or dynamic stereoscopic images can also be achieved.

[0035] Figure 4 This is a schematic diagram of the imaging conversion of a stereoscopic imaging device according to another embodiment of the present invention. Please refer to... Figure 4 In this embodiment, the stereoscopic imaging device 100C includes a light source 110, a light-transmitting sheet 120a, a light-shielding sheet 130a, and a control mechanism 21. Specifically, the light-transmitting sheet 120a is disposed on one side of the light source 110 and is located in the optical path of the light ray 111 emitted by the light source 110. The light-transmitting sheet 120a is, for example, an imaging sheet and includes multiple pattern areas, such as a first pattern area 121, a second pattern area 122, a third pattern area 123, and a fourth pattern area 124.

[0036] For example, the first pattern area 121 has image data corresponding to the first holographic image 121a, and the second pattern area 122 has image data corresponding to the second holographic image 122a. In addition, the third pattern area 123 has image data corresponding to the third holographic image 123a, and the fourth pattern area 124 has image data corresponding to the fourth holographic image 124a.

[0037] In this embodiment, the first pattern area 121, the second pattern area 122, the third pattern area 123, and the fourth pattern area 124 can be arranged in a matrix on the light-transmitting sheet 120a. Additionally, a light-shielding sheet 130a is disposed between the light source 110 and the light-transmitting sheet 120a and is coupled to the control mechanism 21. Specifically, relative displacement can occur between the light-shielding sheet 130a, the light source 110, and the light-transmitting sheet 120a. For example, the positions of the light-transmitting sheet 120a and the light source 110 remain fixed, while the control mechanism 21 controls the light-shielding sheet 130a to rotate between the light source 110 and the light-transmitting sheet 120a, for example, rotating about a vertical axis relative to the light source 110 and the light-transmitting sheet 120a.

[0038] Based on the rotation of the light-shielding plate 130a between the light source 110 and the light-transmitting plate 120a, in one state, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the first pattern area 121. Conversely, the other portion of the light 111 is blocked by the light-shielding plate 130 and cannot be projected onto the second pattern area 122, the third pattern area 123, and the fourth pattern area 124; that is, the light-shielding plate 130 blocks the second pattern area 122, the third pattern area 123, and the fourth pattern area 124.

[0039] In other states, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the fourth pattern area 124. Conversely, other portions of the light 111 are blocked by the light-shielding plate 130 and cannot be projected onto the first pattern area 121, the second pattern area 122, and the third pattern area 123; that is, the light-shielding plate 130 blocks the first pattern area 121, the second pattern area 122, and the third pattern area 123. Alternatively, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the third pattern area 123. Conversely, other portions of the light 111 are blocked by the light-shielding plate 130 and cannot be projected onto the first pattern area 121, the second pattern area 122, and the fourth pattern area 124; that is, the light-shielding plate 130 blocks the first pattern area 121, the second pattern area 122, and the fourth pattern area 124. Or, a portion of the light 111 can pass through the light-shielding plate 130 and be projected onto the second pattern area 122. Conversely, other parts of the light 111 are blocked by the light shield 130 and cannot be projected onto the first pattern area 121, the third pattern area 123 and the fourth pattern area 124, that is, the light shield 130 blocks the first pattern area 121, the third pattern area 123 and the fourth pattern area 124.

[0040] In detail, the light-blocking plate 130a includes a light-transmitting area 131a and a light-blocking area 132a. A portion of the light 111 can pass through the light-transmitting area 131a and be projected onto the light-transmitting plate 120a. The remaining portion of the light 111 is blocked by the light-blocking area 132a and cannot be projected onto the light-transmitting plate 120a. When the light-transmitting area 131a is located in the first pattern area 121, the light-blocking area 132a is located in the second pattern area 122, the third pattern area 123, and the fourth pattern area 124. The first pattern area 121 receives the light 111 from the light source 110, and the light-blocking plate 130a blocks the second pattern area 122, the third pattern area 123, and the fourth pattern area 124, thereby displaying a first high-resolution holographic image 121a above or to one side of the light-transmitting plate 120a.

[0041] When the control mechanism 21 controls the light-shielding plate 130a to rotate relative to the light source 110 and the light-transmitting plate 120a (e.g., rotate 90 degrees counterclockwise) and the light-transmitting area 131a is positioned opposite the fourth pattern area 124, the light-shielding area 132a is positioned opposite the first pattern area 121, the second pattern area 122 and the third pattern area 123, so that the fourth pattern area 124 receives the light 111 from the light source 110, and the light-shielding plate 130a blocks the first pattern area 121, the second pattern area 122 and the third pattern area 123, thereby displaying a high-resolution fourth levitation stereoscopic image 124a above or to one side of the light-transmitting plate 120a.

[0042] When the control mechanism 21 controls the light-shielding plate 130a to rotate relative to the light source 110 and the light-transmitting plate 120a (e.g., rotate 90 degrees counterclockwise) and the light-transmitting area 131a is positioned opposite the third pattern area 123, the light-shielding area 132a is positioned opposite the first pattern area 121, the second pattern area 122 and the fourth pattern area 124, so that the light 111 from the light source 110 is received by the third pattern area 123, and the first pattern area 121, the second pattern area 122 and the fourth pattern area 124 are blocked by the light-shielding plate 130a, thereby displaying a third levitation stereoscopic image 123a with high resolution above or to one side of the light-transmitting plate 120a.

[0043] When the control mechanism 21 controls the light-shielding plate 130a to rotate relative to the light source 110 and the light-transmitting plate 120a (e.g., rotate 90 degrees counterclockwise) and the light-transmitting area 131a is positioned opposite the second pattern area 122, the light-shielding area 132a is positioned opposite the first pattern area 121, the third pattern area 123 and the fourth pattern area 124, so that the second pattern area 122 receives the light 111 from the light source 110, and the light-shielding plate 130a blocks the first pattern area 121, the third pattern area 123 and the fourth pattern area 124, thereby displaying a second levitation stereoscopic image 122a with high resolution above or to one side of the light-transmitting plate 120a.

[0044] It should be noted that the light-blocking plate 130a can rotate clockwise relative to the light source 110 and the light-transmitting plate 120a to sequentially display the first levitation stereoscopic image 121a, the second levitation stereoscopic image 122a, the third levitation stereoscopic image 123a and the fourth levitation stereoscopic image 124a.

[0045] Depending on the imaging requirements, the control mechanism 21 can flexibly control the light-shielding plate 130a to rotate in a counterclockwise or clockwise direction, and is not limited to continuous rotation in a single direction. In addition, the light-shielding plate 130a can also adopt a horizontal movement mechanism (e.g., forward, backward, left, and right movement) to achieve imaging conversion.

[0046] For example, the light-transmitting sheet 120a may contain four patterned areas arranged in a matrix, multiple patterned areas arranged in a ring, or multiple patterned areas arranged in other ways, while the number and arrangement of the light-transmitting areas of the light-shielding sheet 130a can be designed according to the number and arrangement of the patterned areas of the light-transmitting sheet 120a. When any patterned area receives light 111 from the light source 110, a corresponding floating stereoscopic image is displayed above or to one side of the light-transmitting sheet 120a. In one example, these floating stereoscopic images may be different stereoscopic images, each displaying different image content. In another example, these floating stereoscopic images may be similar stereoscopic images, but in different states. Through the rotational displacement generated by the light-shielding sheet 130a, these stereoscopic images can be continuously transformed, thereby achieving a dynamic stereoscopic image display effect.

[0047] In other design modifications, the positions of the light-shielding plate 130a and the light source 110 can remain unchanged. By rotating the light-transmitting plate 120a relative to the light-shielding plate 130a, different stereoscopic or dynamic stereoscopic images can also be displayed.

[0048] Figures 5 to 7 These are schematic diagrams illustrating different control mechanisms employed in the stereoscopic imaging device of the above embodiments. In one example, Figure 1 The stereo imaging device 100 shown is Figure 3 The control mechanism 20 used in the stereoscopic imaging device 100B shown can be specifically accessed through... Figure 5 This is achieved through the control mechanism 200 shown. Figure 1 Taking the stereoscopic imaging device 100 shown as an example, the light-transmitting plate 120 is coupled to the control mechanism 200 so that the linear displacement of the light-transmitting plate 120 is controlled by the control mechanism 200. Figure 3 Taking the stereoscopic imaging device 100B as an example, the light shield 130 is coupled to the control mechanism 200 so that the displacement of the light shield 130 is controlled by the control mechanism 200.

[0049] In detail, the control mechanism 200 may include a carrier 210 and a linear stepper motor 220, wherein the carrier 210 has a light passage opening 211. Figure 1 The light-transmitting sheet 120 shown is or Figure 3 The light-shielding sheet 130 shown can be disposed within the light-passing opening 211. In addition, a linear stepper motor 220 is coupled to one side of the carrier 210 and is adapted to drive the carrier 210 to produce linear displacement, thereby allowing the light-transmitting sheet 120 or the light-shielding sheet 130 disposed within the light-passing opening 211 to move with the carrier 210.

[0050] In other design changes, Figure 3The positions of the light-shielding sheet 130 and the light source 110 shown can remain fixed, and the light-transmitting sheet 120 is disposed in the light passage opening 211. In this way, the light-transmitting sheet 120 disposed in the light passage opening 211 can move with the carrier 210 to change the position of the light 111 projected onto the light-transmitting sheet 120, thereby achieving different display effects of stereoscopic images or dynamic stereoscopic images.

[0051] In one example, Figure 1 The stereo imaging device 100 shown is Figure 3 The control mechanism 20 used in the stereoscopic imaging device 100B shown can be specifically accessed through... Figure 6 This is achieved using the control mechanism 200A shown. Figure 1 Taking the stereoscopic imaging device 100 shown as an example, the light-transmitting sheet 120 is coupled to the control mechanism 200A, so that the displacement of the light-transmitting sheet 120 is controlled by the control mechanism 200A. Figure 3 Taking the stereoscopic imaging device 100B as an example, the light-shielding plate 130 is coupled to the control mechanism 200A so that the displacement of the light-shielding plate 130 is controlled by the control mechanism 200A.

[0052] In detail, the control mechanism 200A includes a carrier 210a, a slide rail 230, a magnet 240, and an electromagnet 250, wherein the carrier 210a has a light-passing opening 211a, and Figure 1 The light-transmitting sheet 120 shown is or Figure 3 The light-shielding plate 130 shown can be disposed within the light passage opening 211a. The carrier 210a is disposed on the slide rail 230, and the magnet 240 can be disposed on the carrier 210a (for example, disposed on the side of the carrier 210a).

[0053] On the other hand, an electromagnet 250 is disposed on one side of the carrier 210a and opposite to the magnet 240. The electromagnet 250 is adapted to generate a magnetic attraction or repulsion force on the magnet 240 to drive the carrier 210a to move on the slide rail 230, thereby allowing the light-transmitting sheet 120 or the light-blocking sheet 130 disposed in the light-passing opening 211a to move with the carrier 210a.

[0054] In other design changes, Figure 3 The positions of the light-shielding sheet 130 and the light source 110 shown can remain fixed, and the light-transmitting sheet 120 is disposed within the light passage opening 211a. In this way, the light-transmitting sheet 120 disposed within the light passage opening 211a can move with the carrier 210a to change the position of the light 111 projected onto the light-transmitting sheet 120, thereby achieving different display effects of stereoscopic images or dynamic stereoscopic images.

[0055] In one example, Figure 2 The stereo imaging device 100A shown is Figure 4The control mechanism 21 used in the stereoscopic imaging device 100C shown can be specifically accessed through... Figure 7 This is achieved through the control mechanism 200B shown. Figure 2 Taking the stereoscopic imaging device 100A shown as an example, the light-transmitting sheet 120a is coupled to the control mechanism 200B, so that the displacement of the light-transmitting sheet 120a is controlled by the control mechanism 200B. Figure 4 Taking the stereoscopic imaging device 100C shown as an example, the light-shielding plate 130a is coupled to the control mechanism 200B so that the displacement of the light-shielding plate 130a is controlled by the control mechanism 200B.

[0056] In detail, the control mechanism 200B includes a carrier 210b, a plurality of magnets 260, and a plurality of electromagnets 270, wherein the carrier 210b has a light-passing opening 211b, and Figure 2 The light-transmitting sheet 120a shown or Figure 4 The light-shielding plate 130a shown can be disposed within the light-passing opening 211b. A plurality of magnets 260 are disposed on the carrier 210b and surround the light-passing opening 211b.

[0057] On the other hand, multiple electromagnets 270 can be arranged in a ring around the carrier 210b, and can generate magnetic attraction or repulsion on the multiple electromagnets 270 to drive the carrier 210b to rotate. In this way, the light-transmitting sheet 120a or the light-blocking sheet 130a disposed in the light-passing opening 211b can rotate with the carrier 210b.

[0058] like Figure 7 As shown, the control mechanism 200B also includes a plurality of ratchet teeth 280 and a pawl 290, wherein the plurality of ratchet teeth 280 can be arranged on the edge of the carrier 210b and surround the light passage opening 211b. The pawl 290 is disposed on one side of the carrier 210b and can engage one of the plurality of ratchet teeth 280 to prevent the carrier 210b from rotating.

[0059] It should be noted that in other examples, the control mechanism 200B may not use a design that includes ratchet teeth 280 and pawl 290, so that the vehicle 210b can rotate not only clockwise but also counterclockwise.

[0060] In other design changes, Figure 4 The positions of the light-shielding sheet 130a and the light source 110 shown can remain fixed, and the light-transmitting sheet 120a is arranged in the light passage opening 211b. In this way, the light-transmitting sheet 120a arranged in the light passage opening 211b can rotate with the carrier 210b to change the position of the light 111 projected onto the light-transmitting sheet 120a, thereby realizing different display effects of stereoscopic images or dynamic stereoscopic images.

[0061] Figure 8 and Figure 9This is a schematic diagram of the imaging conversion of a stereoscopic imaging device according to another embodiment of the present invention. Please refer to... Figure 8 In one example, the stereoscopic imaging device 100D includes a light source 110, a light-transmitting plate 120b, a light-blocking plate 130b, and a control mechanism 200C. Specifically, the light-transmitting plate 120b is disposed on one side of the light source 110 and located in the optical path of the light ray 111 emitted by the light source 110. The light-transmitting plate 120b may be an imaging plate and includes multiple pattern areas, for example, three pattern areas 125, 126, and 127 arranged linearly. Each pattern area has image data corresponding to a predetermined holographic image to be displayed.

[0062] On the other hand, the light-shielding plate 130b is disposed between the light source 110 and the light-transmitting plate 120b, and has a light-transmitting opening 133. The positions of the light-shielding plate 130b and the light source 110 remain fixed, and the light-transmitting plate 120b is coupled to the control mechanism 200C. Furthermore, the control mechanism 200C includes a first roller 201 and a second roller 202 arranged in parallel, wherein the opposite ends of the light-transmitting plate 120b are respectively wound around the first roller 201 and the second roller 202, and the first roller 201 and the second roller 202 are adapted to drive the light-transmitting plate 120b to produce a linear displacement relative to the light-shielding plate 130b, so as to adjust the relative positional relationship between the three pattern areas 125, 126, 127 and the light-transmitting opening 133.

[0063] In one state, the light-transmitting opening 133 is located in the pattern area 125, while the other two pattern areas 126 and 127 are blocked by the light-blocking plate 130b. The light 111 emitted by the light source 110 passes through the light-transmitting opening 133 and is projected onto the pattern area 125 so that the pattern area 125 receives the light 111, thereby displaying a high-resolution holographic image 125a above or to one side of the light-transmitting plate 120b.

[0064] In another state, the light-transmitting opening 133 is located in the pattern area 126, while the other two pattern areas 125 and 127 are blocked by the light-shielding sheet 130b. The light 111 emitted by the light source 110 passes through the light-transmitting opening 133 and is projected onto the pattern area 126 so that the pattern area 126 receives the light 111, thereby displaying a high-resolution holographic image 126a above or to one side of the light-transmitting sheet 120b.

[0065] Figure 9 The stereo imaging device 100E shown is... Figure 8 The design of the stereo imaging device 100D shown is similar. Figure 9In the stereoscopic imaging device 100E shown, the positions of the light-transmitting sheet 120b and the light source 110 remain fixed, and the opposite ends of the light-shielding sheet 130b are respectively wound around the first roller 201 and the second roller 202. The first roller 201 and the second roller 202 are adapted to drive the light-shielding sheet 130b to produce a linear displacement relative to the light-transmitting sheet 120b, so as to adjust the relative positional relationship between the light-transmitting opening 133 and the three pattern areas 125, 126, and 127.

[0066] Figure 10 This is a schematic diagram of a combination of a light-transmitting sheet and a light-blocking sheet according to another embodiment of the present invention. Please refer to... Figure 10 In this embodiment, the first pattern area 221 of the light-transmitting sheet 22 may include at least a plurality of first sub-pattern areas 2211 arranged at intervals, and the second pattern area 222 includes a plurality of second sub-pattern areas 2221 arranged at intervals. The plurality of first sub-pattern areas 2211 and the plurality of second sub-pattern areas 2221 are arranged alternately on the light-transmitting sheet 22, wherein each first sub-pattern area 2211 has an image corresponding to the first levitation stereoscopic image 221a, and each second sub-pattern area 2221 has an image corresponding to the second levitation stereoscopic image 222a.

[0067] Accordingly, the light-transmitting area 331 of the light-shielding sheet 33 includes a plurality of sub-light-transmitting areas 3311 spaced apart, and the light-shielding area 332 includes a plurality of sub-light-shielding areas 3321 spaced apart. The plurality of sub-light-transmitting areas 3311 and the plurality of sub-light-shielding areas 3321 are arranged alternately on the light-shielding sheet 33, and a rotational displacement mechanism can be used to move the light-shielding sheet 33 to control the plurality of sub-light-transmitting areas 3311 to be located in a plurality of first sub-pattern areas 2211 and the plurality of sub-light-shielding areas 3321 to be located in a plurality of second sub-pattern areas 2221. This allows the first pattern areas 221 to receive light 111 from the light source 110, while the light-shielding sheet 33 blocks the second pattern areas 222, thereby creating a light-shielding effect above the light-transmitting sheet 22. Alternatively, a first levitation stereoscopic image 221a with high resolution may be displayed on one side, or multiple sub-transmitting areas 3311 may be controlled to be located in multiple second sub-pattern areas 2221 and multiple sub-shielding areas 3321 may be located in multiple first sub-pattern areas 2211, so that light 111 from light source 110 is received by the second pattern area 222 and the first pattern area 221 is blocked by the light-shielding sheet 33, thereby displaying a second levitation stereoscopic image 222a with high resolution above or on one side of the transmitting sheet 22.

[0068] In other examples, the light-shielding plate 33 may also use linear displacement or other movement mechanisms to achieve imaging conversion. Alternatively, the light-shielding plate 33 may remain stationary while the light-transmitting plate 22 may use rotational displacement, linear displacement or other movement mechanisms to adjust the alignment of the first pattern area 221 and the second pattern area 222 of the light-transmitting plate 22 with respect to the light-transmitting area 331 and the light-shielding area 332 of the light-shielding plate 33 to achieve imaging conversion.

[0069] Figure 11 This is a schematic diagram of a combination of a light-transmitting sheet and a light-blocking sheet according to another embodiment of the present invention. Please refer to... Figure 11 In this embodiment, the light-transmitting sheet 40 may include multiple staggered patterned areas, such as multiple first patterned areas 41, multiple second patterned areas 42, multiple third patterned areas 43, and multiple fourth patterned areas 44. The multiple first patterned areas 41 have image data corresponding to the first holographic image 60, and the multiple second patterned areas 42 have image data corresponding to the second holographic image 61. Furthermore, the multiple third patterned areas 43 have image data corresponding to the third holographic image 62, and the multiple fourth patterned areas 44 have image data corresponding to the fourth holographic image 63.

[0070] Specifically, any first pattern area 41 is not adjacent to any other first pattern area 41 and is surrounded by one or more second pattern areas 42, one or more third pattern areas 43, and / or one or more fourth pattern areas 44. Any second pattern area 42 is not adjacent to any other second pattern area 42 and is surrounded by one or more first pattern areas 41, one or more third pattern areas 43, and / or one or more fourth pattern areas 44. Any third pattern area 43 is not adjacent to any other third pattern area 43 and is surrounded by one or more first pattern areas 41, one or more second pattern areas 42, and / or one or more fourth pattern areas 44. Any fourth pattern area 44 is not adjacent to any other fourth pattern area 44 and is surrounded by one or more first pattern areas 41, one or more second pattern areas 42, and / or one or more third pattern areas 43.

[0071] On the other hand, the multiple light-transmitting areas 51 on the light-shielding plate 50 can be arranged at intervals according to the arrangement rules of different pattern areas and surrounded by the light-shielding area 52. After each rotation of a preset angle (e.g., 90 degrees), the multiple light-transmitting areas 51 are only located in specific pattern areas, and the light-shielding area 52 blocks other pattern areas to achieve image conversion.

[0072] In one implementation, all light-transmitting areas 51 of the rotated light-blocking sheet 50 are located in all first pattern areas 41, and all second pattern areas 42, all third pattern areas 43 and all fourth pattern areas 44 are blocked by the light-blocking area 52, so that light from the light source 110 is received by all first pattern areas 41, thereby displaying a first levitation stereoscopic image 60 with high resolution above or on one side of the light-transmitting sheet 40.

[0073] In one implementation, all light-transmitting areas 51 of the rotated light-blocking sheet 50 are located in all second pattern areas 42, and all first pattern areas 41, all third pattern areas 43 and all fourth pattern areas 44 are blocked by the light-blocking areas 52, so that light from the light source 110 is received by all second pattern areas 42, thereby displaying a second levitation stereoscopic image 61 with high resolution above or on one side of the light-transmitting sheet 40.

[0074] In one implementation, all light-transmitting areas 51 of the rotated light-blocking sheet 50 are located in all third pattern areas 43, and all first pattern areas 41, all second pattern areas 42 and all fourth pattern areas 44 are blocked by the light-blocking area 52, so that light from the light source 110 is received by all third pattern areas 43, thereby displaying a third levitation stereoscopic image 62 with high resolution above or on one side of the light-transmitting sheet 40.

[0075] In one implementation, all light-transmitting areas 51 of the rotated light-blocking sheet 50 are located in all fourth pattern areas 44, and all first pattern areas 41, all second pattern areas 42 and all third pattern areas 43 are blocked by the light-blocking area 52, so that light from the light source 110 is received by all fourth pattern areas 44, thereby displaying a fourth levitation stereoscopic image 63 with high resolution above or on one side of the light-transmitting sheet 40.

[0076] In summary, in the stereoscopic imaging device of the present invention, multiple image data zones of a plurality of predetermined floating stereoscopic images are formed on a light-transmitting sheet to constitute multiple pattern areas. Through linear or rotational displacement generated by the light-transmitting sheet, or through displacement generated by the light-shielding sheet, a light source can be projected onto different pattern areas, thereby displaying different high-resolution stereoscopic images or dynamic stereoscopic images.
