Description

  The present invention relates to a stereoscopic display medium, and more particularly to a high-quality stereoscopic display medium that suppresses a decrease in resolution and further combines vertical and horizontal resolutions in a stereoscopic display medium that combines a lenticular lens and a printed material or a display panel. is there.

  Conventionally, a three-dimensional printed material combining a printed material and a lenticular lens is well known. In order to align the axial direction of the lenticular lens with the vertical direction of the printed material, this is a method of increasing the number of horizontal parallaxes at the expense of the resolution in the horizontal direction. In this method, since the resolution in the vertical direction is high, but the resolution in the horizontal direction is low, the appearance of the image is not preferable.

On the other hand, a three-dimensional display combining a liquid crystal display and a lenticular lens has been devised. In order to increase the number of parallaxes in the horizontal direction, for example, in Patent Document 1 and Non-Patent Document 1, a lenticular lens is obliquely arranged with respect to a vertical pixel arrangement of a liquid crystal display. By arranging, a stereoscopic display has been devised in which both the resolution in the horizontal direction and the vertical direction are sacrificed and the number of parallaxes in the horizontal direction is increased. In this method, the number of parallaxes in the horizontal direction can be increased at the expense of a good balance between the resolution in the horizontal direction and the vertical direction, so that the number of parallaxes can be increased and a decrease in resolution can be suppressed.
Japanese Patent Laid-Open No. 9-236777 “Three-Dimensional Image Conference 2004 Proceedings” pp. 17-20, Yuki Ebizawa, Yasuhiro Takagi “Thin-Three-Dimensional Display Displaying 72 Directional Images” (2004. 6.29 (Kogakuin University), (3D Image Conference 2004 Executive Committee))

  However, in the case of a liquid crystal display, since the configuration is usually a combination of a color filter and a liquid crystal display panel, three pixels of R (red), G (green), and B (blue) are used to display one full color pixel. In order to make the aspect ratio of a full color image 1: 1, it is common to use pixels with an aspect ratio of 3: 1.

  A three-dimensional printed matter having the same configuration can be realized by printing, but this is not preferable because unnecessary resolution reduction and brightness reduction occur.

  Further, the aspect ratio of the pixels of the stereoscopic image is not always 1: 1, and it cannot be said that the quality of the stereoscopic image is high.

  The present invention has been made in view of such problems of the prior art, and an object of the present invention is to increase the number of parallaxes in a three-dimensional display medium in which a printed material or a display panel and a lenticular lens are combined. In the case where the resolution is sacrificed in both the horizontal direction and the vertical direction, a reduction in resolution is suppressed, and a high-quality stereoscopic display medium that combines the vertical and horizontal resolutions is provided.

The three-dimensional display medium of the present invention that achieves the above object has a pixel unit in which one or a plurality of pixels are arranged adjacent to each other in the horizontal direction, which is a parallax direction, in order to display a pixel unit of a desired color. In the vertical direction, a lenticular lens is superimposed on a display medium in which the same pixel unit array as the horizontal pixel unit repeating array is arranged in parallel, and the generatrix direction of the cylindrical lens of the lenticular lens is relative to the vertical direction. In a stereoscopic display medium in which lenticular lenses are arranged in an oblique direction forming an angle,
The number of pixel units in the horizontal direction of the display medium corresponding to the repeating unit in the horizontal direction of the cylindrical lens of the lenticular lens is M, and the vertical number of pixels corresponding to the same cylindrical lens of the lenticular lens is shifted by one in the vertical direction. When the number of pixel units in the direction is N (≠ 1), the number of pixels constituting one pixel unit in the horizontal direction is m, and the ratio of the vertical dimension to the horizontal dimension of one pixel is n,
n <3 (1)
m <3 (2)
m × M = n × N (3)
Satisfying at least one, preferably a plurality of the above.

  Note that the display medium includes a printed matter or a display panel.

  In the present invention, since at least one of the conditions (1) to (3) is satisfied, a reduction in resolution is suppressed, and furthermore, a high-quality three-dimensional printed material and a three-dimensional display panel can be obtained by matching the vertical and horizontal resolutions. A stereoscopic display medium such as the above can be obtained.

  Hereinafter, first, a three-dimensional printed material will be described as an example of the three-dimensional display medium of the present invention, and description will be made based on the example.

  First, we will define terms. The minimum unit of display is called a pixel. In order to display one pixel of a desired color, a set of pixels in which one or a plurality of pixels are adjacently arranged in the horizontal direction, which is the parallax direction, for example, a set of R pixels, G pixels, and B pixels is defined as a pixel unit. . A set of pixel units at positions corresponding to each other in a set of parallax images for displaying a stereoscopic image is defined as a stereoscopic pixel.

  FIG. 6A is a diagram illustrating a relationship between one stereoscopic pixel of a conventional stereoscopic print and a lenticular lens. One stereoscopic pixel 10 parallaxes a pixel 1 corresponding to an image having a different parallax direction in the horizontal direction. In this case, twelve are arranged side by side. Then, one cylindrical lens 2 of the lenticular lens corresponding to the one three-dimensional pixel 10 is superposed with its generatrix (focal line) direction oriented in the vertical direction perpendicular to the parallax method (lateral direction). Because of such a configuration, when a printed material composed of such a set of three-dimensional pixels 10 is viewed with both eyes through a lenticular lens in which the cylindrical lens 2 is repeatedly arranged in the lateral direction, the right eye has the lenticular lens. The pixel 1 incident through the cylindrical lens 2 is different from the pixel 1 incident on the left eye through the same cylindrical lens 2 of the lenticular lens, and these pixels 1 correspond to parallax images in the parallax direction of the right eye and the left eye, respectively. Therefore, a 3D (stereoscopic) image can be observed.

  As described above, in the conventional three-dimensional printed material, one three-dimensional pixel 10 is a horizontally long three-dimensional pixel configured by arranging pixels 1 corresponding to the number of parallaxes in the horizontal direction, and the aspect ratio is 1: 1. In addition, the resolution in the vertical direction and the horizontal direction are not balanced, and a high-quality three-dimensional printed matter cannot always be said.

  FIG. 6B is a diagram (Non-Patent Document 1) showing a relationship between one stereoscopic pixel and a lenticular lens in a stereoscopic display in which a conventional liquid crystal display and a lenticular lens are combined. In this case, the liquid crystal display is R The pixel units 11 including m = 3 pixels 1R, B pixels 1B, and G pixels 1G are repeatedly arranged in the horizontal direction, and the vertical arrangement is the same as the repeated arrangement of the pixel units 11 in the horizontal direction. A cylindrical lens 2 of a lenticular lens is disposed obliquely with respect to the arrangement of the vertical pixel units 11 of the display. In the case of FIG. 6B, one cylindrical lens 2 corresponds to M = 4 pixel units 11 in the horizontal direction (parallax direction), and N = 6 pixel units 11 in the vertical direction. The cylindrical lens 2 is disposed obliquely with respect to the pixel array so that exactly one pixel unit 11 is displaced in the horizontal direction with respect to the set of the above. And 24 pixel units 11 covered in this range, that is, a pixel unit having 24 R pixels 1R, B pixels 1B, and G pixels 1G in the vertical and horizontal directions constitute one stereoscopic pixel 10. 24 parallax images are reproduced through a lenticular lens formed by arranging cylindrical lenses 2 in parallel. In FIG. 7, only the R pixel 1R in one three-dimensional pixel 10 is extracted and the arrangement position thereof is shown. The numbers after “R” in FIG. 7 indicate the parallax numbers. As the parallax direction moves from right to left, the pixels of R24 enter the field of view through the cylindrical lens 2 in order from R1.

  In this case, if the horizontal dimension of one pixel is 1, and the ratio of the vertical dimension to the horizontal dimension is n = 3, the dimension of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (N × N) = (3 × 4) × (3 × 6) = 12 × 18, and the horizontal direction is the same as that of the three-dimensional printed material in FIG. 6A, but the vertical direction is 18 times. It can be seen that the resolution is very poor even taking into account that the number of parallax images is doubled.

  Therefore, in the present invention, as a printed matter, the ratio n of the vertical dimension to the horizontal dimension of the pixels 1, 1R, 1B, and 1G and the number m of the pixels 1, 1R, 1B, and 1G constituting the pixel unit 11 are adjusted. Consider that the horizontal and vertical dimensions of the three-dimensional pixel 10 are further reduced to increase the resolution.

  FIG. 1 shows the case where the vertical dimensions of the pixels 1R, 1B, and 1G are shorter than 3 and n <3, and n = 1 (FIG. 1A) and n = 2 (FIG. 1B). It is a figure which shows the relationship between the one three-dimensional pixel 10 and the lenticular lens 2 in the three-dimensional printed matter which combined the printed matter corresponding to 6 (b), and a lenticular lens. The number of pixel units 11 in the horizontal direction of the stereoscopic pixel 10 is M = 4, the number of pixel units in the vertical direction is N = 6, the number of parallaxes is M × N = 24, and the number of pixels constituting the pixel unit 11 M = 3 (R pixel 1R, B pixel 1B, G pixel 1G), which is the same as in FIG. 6B.

  In the case of n = 1 in FIG. 1A, the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (3 × 4) × (1 × 6) = 12. × 6, which is three times the vertical resolution in the case of FIG. The horizontal resolution is the same.

  In the case of n = 2 in FIG. 1B, the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (3 × 4) × (2 × 6) = 12. × 12, which is 1.5 times the vertical resolution in the case of FIG. The horizontal resolution is the same as in the case of FIG. In this example, the vertical and horizontal resolutions are the same.

  FIG. 2 is a diagram in the case where the number m of pixels constituting the pixel unit 11 is smaller than 3 and m <3, and m = 2 (FIG. 2B) and m = 1 (FIG. 2C). It is a figure which shows the relationship between the one three-dimensional pixel 10 and the lenticular lens 2 in the three-dimensional printed matter which combined the printed matter corresponding to 6 (b), and a lenticular lens. The number of pixel units 11 in the horizontal direction of the stereoscopic pixel 10 is M = 4, the number of pixel units in the vertical direction is N = 6, the number of parallaxes is M × N = 24, and the vertical direction of the pixels 1R, 1B, and 1G is The dimension is n = 3, which is the same as in FIG.

Further, R pixel 1R, B pixel 1B and G pixel 1G of one pixel unit 11 are combined. FIG. 2C shows a single full-color pixel 1F added by additive color mixing.

  FIG. 2B shows that one pixel unit 11 is composed of a pixel 1RB and a G pixel 1G obtained by adding the R pixel 1R and the B pixel 1B by additive color mixing, and m = 2, and the size of one stereoscopic pixel 10 Is horizontal × vertical = (m × M) × (n × N) = (2 × 4) × (3 × 6) = 8 × 18, and the horizontal resolution in the case of FIG. 5 times. The vertical resolution is the same.

  In FIG. 2C, one pixel unit 11 is composed of one full-color pixel 1F in which R pixel 1R, B pixel 1B, and G pixel 1G are added together by additive color mixing, m = 1, The dimensions of the pixel 10 are horizontal × vertical = (m × M) × (n × N) = (1 × 4) × (3 × 6) = 4 × 18, which is the horizontal direction in the case of FIG. Three times the resolution. The vertical resolution is the same.

  2 (b) and 2 (c) are characterized in that the pixels 1RB and 1F of the printed matter are printed with the additive color mixed ink at the positions, so that FIG. 2 (b) is changed from FIG. 2 (a) to FIG. FIG. 2C shows that a brighter image than that shown in FIG. 2B can be displayed (the brightness comparison is obvious if the brightness when displaying white is compared).

  FIG. 3 shows a state in which the vertical dimensions of the pixels 1R, 1B, 1G, 1RG, and 1F are set to n = 2, which is shorter than 3, in the states of FIGS. 2 (a), (b), and (c). FIG. 3 is a view similar to FIG. The number of pixel units 11 in the horizontal direction of the stereoscopic pixel 10 is M = 4, the number of pixel units in the vertical direction is N = 6, and the number of parallaxes is M × N = 24.

  3A shows a case where m = 2 and n = 2 from the state of FIG. 6B, and the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × ( n × N) = (3 × 4) × (2 × 6) = 12 × 12, which is 1.5 times the vertical resolution in the case of FIG. The horizontal resolution is the same. In this example, the vertical and horizontal resolutions are the same (same as in FIG. 1B).

  FIG. 3B shows that one pixel unit 11 includes a pixel 1RB and a G pixel 1G obtained by adding the R pixel 1R and the B pixel 1B by additive color mixing, and m = 2 and n = 2. The size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (2 × 4) × (2 × 6) = 8 × 12. In the case of FIG. The horizontal resolution is 1.5 times the vertical resolution, and the vertical resolution is 1.5 times that in the case of FIG.

  In FIG. 3C, one pixel unit 11 is composed of 1F1 full-color pixels in which R pixel 1R, B pixel 1B, and G pixel 1G are added together by additive color mixing, m = 1, and n = Therefore, the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (1 × 4) × (2 × 6) = 4 × 12. The resolution in the horizontal direction in the case of b) is three times, and the resolution in the vertical direction is 1.5 times that in the case of FIG.

  FIG. 4 is a diagram when the vertical dimensions of the pixels 1R, 1B, 1G, 1RG, and 1F are set to n = 1, which is shorter than 3, in the states of FIGS. 2 (a), (b), and (c). 1 and FIG. The number of pixel units 11 in the horizontal direction of the stereoscopic pixel 10 is M = 4, the number of pixel units in the vertical direction is N = 6, and the number of parallaxes is M × N = 24.

  FIG. 4A shows a case where m = 1 and n = 1 from the state of FIG. 6B, and the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × ( n × N) = (3 × 4) × (1 × 6) = 12 × 6, which is three times the vertical resolution in the case of FIG. The horizontal resolution is the same.

  FIG. 4B shows that one pixel unit 11 is composed of a pixel 1RB and a G pixel 1G obtained by adding the R pixel 1R and the B pixel 1B by additive color mixing, and m = 2 and n = 1. The size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (2 × 4) × (1 × 6) = 8 × 6, as shown in FIG. 6B. The horizontal resolution is 1.5 times, and the vertical resolution is three times that of FIG.

  In FIG. 4C, one pixel unit 11 is composed of 1F1 full-color pixels obtained by adding the R pixel 1R, the B pixel 1B, and the G pixel 1G by additive color mixture, and m = 1. Therefore, the size of one three-dimensional pixel 10 is horizontal × vertical = (m × M) × (n × N) = (1 × 4) × (1 × 6) = 4 × 6. The resolution in the horizontal direction in the case of b) is three times, and the resolution in the vertical direction is three times that in the case of FIG.

As described above, in the three-dimensional printed material of the present invention, the ratio n of the vertical dimension to the horizontal dimension of one pixel is as follows.
n <3 (1)
Or for the number m of pixels constituting one pixel unit,
m <3 (2)
Satisfying this is necessary for improving the resolution in the vertical or horizontal direction.

To balance the horizontal and vertical resolution,
m × M = n × N (3)
It is desirable to satisfy

  Regarding the above conditions (1) to (3), it is more preferable that any one of a plurality of conditions or all the conditions are satisfied.

  By the way, in the stereoscopic display in which the conventional liquid crystal display and the lenticular lens shown in FIG. 6B are combined, the same arrangement as the repeated arrangement of the pixel units 11 in the horizontal direction is arranged in the vertical direction. Although the cylindrical lens 2 of the lenticular lens is arranged obliquely with respect to the arrangement of the pixel units 11, as shown in FIG. 8A, the same arrangement as the repetitive arrangement of the pixel units 11 in the horizontal direction is fixed. In the case of the phase shown in FIG. 8A, a similar three-dimensional display can also be realized by shifting in the vertical direction while sequentially shifting by one pixel in the horizontal direction. FIG. 8B shows the arrangement positions of the R pixel 1R, the B pixel 1B, and the G pixel 1G in one stereoscopic pixel 10 in the case of FIG. 8A. The numbers after “R”, “B”, and “G” in FIG. 8B indicate the parallax numbers, and as the parallax direction moves from right to left, R1, B1, and G1 sequentially, R24, Each primary color pixel of B24 and G24 enters the field of view through the cylindrical lens 2.

Even in the configuration of the three-dimensional pixel 10 as shown in FIG. 8A, based on the present invention,
n <3 (1)
m <3 (2)
m × M = n × N (3)
It is possible to satisfy at least one of the following. Hereinafter, an example will be described with reference to FIG. FIG. 5 is a view similar to FIG. 8 of the example corresponding to FIG. This example corresponds to a case where the vertical dimensions of the pixels 1R, 1B, and 1G in FIG. 8 are shorter than 3 and n = 2, and the size of one stereoscopic pixel 10 is horizontal × vertical = (mx M) × (n × N) = (3 × 4) × (2 × 6) = 12 × 12, which is 1.5 times the vertical resolution in the case of FIG. The horizontal resolution is the same as in FIG. In this example, the vertical and horizontal resolutions are the same.

  In contrast to the configuration of the three-dimensional pixel 10 as shown in FIG. 8A, the other FIGS. 1A, 2B and 2C, FIGS. 3A to 3C, and FIG. ) To (c), the horizontal and vertical resolutions can be increased, and the vertical and horizontal resolutions can be matched.

  As mentioned above, although the three-dimensional display medium of this invention has been demonstrated based on the Example of a three-dimensional printed matter, this invention is not limited to these Examples, A various deformation | transformation is possible. In the above embodiment, the number of parallaxes is M × N = 24, but it is needless to say that the number of parallaxes may be increased or decreased by changing M or N, or both. Further, when one of m or n is smaller than 3, it is obvious that the other may be 3 or more.

  The above description is a case where the stereoscopic display medium of the present invention is applied to a printed material. Instead of the printed material, a combination of a lenticular lens and a liquid crystal display that constitutes one pixel unit with three pixels of R, G, and B The present invention can be applied to a liquid crystal display based on a field sequential (FS) system and a display based on an EDP (display utilizing an electrophoretic phenomenon) system.

  Here, the FS type liquid crystal display does not use a color filter, but instead, red, blue, and green LEDs (light emitting diodes) blink in order 60 times per second at high speed to express a desired color with one pixel. Just like the combination of the three primary colors turns white, the human eye appears as white with a kind of afterimage phenomenon, and the color can be expressed by increasing the frequency of red and blue ( http://it.nikkei.co.jp/it/utility/word.cfm?wordid=259).

  In addition, an EDP type display encloses a charged toner between two plastic films and electrically changes the in-plane distribution of the toner to form an image. Since the toner adsorbed on the electrode surface maintains its state even when it is cut, the display image is non-volatile. In addition, color display is possible by dividing one pixel into RGB or layering three layers of CMY on top and bottom (http://web.canon.jp/technology/detail/device/pl_display/ ).

  Therefore, even in the FS liquid crystal display and the EDP display, a stereoscopic display medium with m = 1 can be realized in the present invention.

  As described above, in the present invention, a conventional liquid crystal display and an obliquely arranged lenticular lens are combined to increase the number of horizontal parallaxes at the expense of both the horizontal and vertical resolutions. When applying the 3D display method to 3D display media such as printed matter or display panels, the quality of the balance between the resolution of the 3D image and the resolution in the vertical and horizontal directions is improved by brushing up the pixel conditions premised on the LCD It is something to be made.
