[0014] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the description of the drawings, the same parts are given the same reference numerals and the description will be omitted.

[0015] (display medium) A display medium 1 according to an embodiment of the present disclosure can display content decorated with a variety of patterns. FIG. 1 is a diagram illustrating an example of content displayed by the display medium 1. The display medium 1 displays an image decorated with a pattern in which the color of a given content changes from one color to another. A user viewing the display medium 1 perceives the color of the given content as having a structural color or iridescent color, or as having a sparkling decoration. In the present disclosure, content refers to content that includes images, such as still images, videos, and videos with audio.

[0016] As shown in FIG. 1, the display medium 1 displays the reference content D in a first direction D1, displays the first converted content Ja in a second direction D2, and displays the second converted content Jb in a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are different from each other. The first converted content Ja and the second converted content Jb are contents obtained by converting the color of the reference content D with the same composition. The first converted content Ja and the second converted content Jb have the same composition and color tone. The first converted content Ja and the second converted content Jb have the color converted by different methods. When the first converted content Ja and the second converted content Jb are not particularly distinguished from each other, they may be simply referred to as the converted content J.

[0017] The display medium 1 displays three pieces of content with the same composition but different colors in different directions. A user views the display medium 1 by changing the viewpoint relative to the display medium 1. At this time, the user may change the viewpoint relative to the display medium 1, or the user may move the display medium 1. The display medium 1 can display to the user content with one common composition but with colors that change one after another, and therefore can display content decorated with a rich variety of colors.

[0018] 1, the display medium 1 displays one reference content D and two converted contents J in three directions, but is not limited to this. The display medium 1 may display multiple contents with the same composition but different colors in each of two or more directions. The display medium 1 may not display the reference content D, but may display two or more converted contents J with the same composition as the reference content D but different colors.

[0019] (First embodiment) A display medium 1 according to a first embodiment will be described with reference to FIG. 2. The display medium 1 according to the first embodiment has the configuration of the display medium described in Patent Document 3. As shown in FIG. 2, the display medium 1 includes a substrate 201. The substrate 201 may be in the form of a thin sheet such as paper, or may be in a three-dimensional shape. The substrate 201 may have a flat or curved upper surface. As shown in FIG. 2, the display medium 1 has a plurality of cells C on its surface. In the example shown in FIG. 2, the user's viewpoint is located above in the Z-axis direction (thickness direction). In the example shown in FIG. 2, the display medium 1 has a rectangular parallelepiped shape, but the shape is not important.

[0020] As shown in Fig. 3, the display medium 1 has an upper layer Lu and a lower layer Lb. The names of the upper layer Lu and the lower layer Lb are unrelated to the direction of gravity and are not dependent on the arrangement of the display medium 1. In the first embodiment, the layer closer to the user's viewpoint is called the upper layer Lu. The layer farther from the user's viewpoint is called the lower layer Lb.

[0021] As shown in FIG. 3 and FIG. 4, the upper layer Lu and the lower layer Lb are formed on the XY plane and arranged in parallel to the Z-axis direction. The display medium 1 displays a plurality of contents corresponding to a plurality of directions based on the portion of the light in a plurality of directions passing through the upper layer Lu and the lower layer Lb. Each content is visually recognized at each viewpoint provided at the position where the light in a plurality of directions passing through the upper layer Lu and the lower layer Lb is incident. The display medium 1 displays a plurality of contents because the combination of the color of the portion passing through the upper layer Lu and the color of the portion passing through the lower layer Lb is different for each direction. The display medium 1 displays the contents at three different viewpoints above the upper layer Lu and the lower layer Lb in the Z-axis direction. The three different viewpoints differ at least in the value (coordinate) in the X-axis direction and the value (coordinate) in the Y-axis direction.

[0022] In the first embodiment, the light in a predetermined direction used when displaying the content is emitted from at least a direction facing the viewpoint with respect to the upper layer Lu and the lower layer Lb. When the viewpoint is provided above the upper layer Lu and the lower layer Lb in the Z-axis direction, the light may be emitted from below the upper layer Lu and the lower layer Lb in the Z-axis direction, and the position of the light source does not matter. The light directed from below the lower layer Lb in the Z-axis direction to above may be, for example, light from a light source provided at an arbitrary position reflected by the base material M, or light from a light source provided on the base material M. Alternatively, the light may be light irradiated from a light source (not shown) provided on the back side of the base material M and transmitted through the base material M.

[0023] 3, a transparent layer N is formed between an upper layer Lu and a lower layer Lb. A base material M is provided on the lower layer Lb in the opposite direction to the transparent layer N in the Z-axis direction. The display medium 1 is formed by stacking these members in the order of the base material M, the lower layer Lb, the transparent layer N, and the upper layer Lu in the Z-axis direction.

[0024] The transparent layer N is preferably formed of a material that transmits a large amount of light without absorbing color components of light (visible light). The transparent layer N is formed of a transparent material such as water or transparent plastic. The transparent layer N may be formed of air. In other words, the upper layer Lu and the lower layer Lb may be arranged parallel to each other at a predetermined distance. The base material M is formed of a material such as a mirror or white paper that allows the colors given to the upper layer Lu and the lower layer Lb to be easily visible.

[0025] As shown in FIG. 3 and FIG. 4, the upper surface layer Lu is formed of a transparent member and has a plurality of upper surface cells Cu. Each of the plurality of upper surface cells Cu has a color region. The lower surface layer Lb is formed of a transparent member and has a plurality of lower surface cells Cb. Each of the plurality of lower surface cells Cb has a color region. A printer or the like that gives color to the color regions of the upper surface cells Cu and the lower surface cells Cb by a predetermined definition of the respective positions of the upper surface cells Cu and the lower surface cells Cb may specify the positions of each color region, and the respective positions of the upper surface cells Cu and the lower surface cells Cb may not be visually recognized. For example, there may be no clear division such as a line, partition, or recess between two adjacent upper surface cells Cu or two lower surface cells Cb. The two adjacent upper surface cells Cu or two lower surface cells Cb may not be physically separated. Furthermore, at the boundary between two adjacent top surface cells Cu or two bottom surface cells Cb, the ends of the two cells may be given the same color or the same colorlessness, so that the adjacent cells C are not necessarily visible.

[0026] In the first embodiment, each top surface cell Cu of the top surface layer Lu and each bottom surface cell Cb of the bottom surface layer Lb are formed by dividing each layer in the same manner. That is, each top surface cell Cu of the top surface layer Lu is formed at a position shifted in the Z-axis direction from each bottom surface cell Cb of the bottom surface layer Lb while keeping the positions in the X-axis direction and Y-axis direction as they are. More specifically, as shown in FIG. 4, in the embodiment of the present invention, the top surface cell Cu of the top surface layer Lu is formed at a position shifted in the Z-axis direction from the bottom surface cell Cb of the bottom surface layer Lb. The same is true for other cells. In the first embodiment, the relationship between the cells formed at positions shifted in the Z-axis direction, such as the top surface cell Cu and the bottom surface cell Cb, is called "corresponding". In the first embodiment, the corresponding top surface cell Cb and bottom surface cell Cb are described as being in the same position in the X-axis direction and Y-axis direction, and only the positions in the Z-axis direction are different, but this is not limited to this. As another embodiment, the corresponding upper surface cell Cb and lower surface cell Cb may be shifted in position in the X-axis direction or the Y-axis direction in addition to the Z-axis direction.

[0027] In the first embodiment, cell C includes an upper surface cell Cu of an upper surface layer Lu and a lower surface cell Cb of a lower surface layer Lb that overlaps (corresponds to) the upper surface cell Cu. Cell C is specified by a combination of corresponding upper surface cells Cu and lower surface cells Cb among each upper surface cell Cu of the upper surface layer Lu and each lower surface cell Cb of the lower surface layer Lb.

[0028] As shown in FIG. 4, in the first embodiment, markers Vu and Vb are provided on the upper layer Lu and the lower layer Lb, respectively. When the display medium 1 is formed by overlapping two transparent members, and the two transparent members are appropriately overlapped, the markers Vu and Vb provided on each of the two transparent members overlap. Here, in this disclosure, the case of appropriate overlapping refers to the case where the upper layer Lu and the lower layer Lb are overlapped as designed for the display medium 1. The case of appropriate overlapping is specifically the case where the reference content D is displayed in a first direction and the converted content J is displayed in a second direction.

[0029] In the present disclosure, a case will be described in which the markers Vu and Vb overlap to indicate the position where the top layer Lu and the bottom layer Lb overlap, but this is not limited thereto. The markers Vu and Vb only need to indicate the position where the top layer Lu and the bottom layer Lb appropriately overlap.

[0030] As shown in Figures 3 to 5, the upper layer Lu is formed of a transparent material and has a plurality of upper cells Cu. Each of the plurality of upper cells Cu has color regions G11 and G12. The lower layer Lb is formed of a transparent material and has a plurality of lower cells Cb. Each of the plurality of lower cells Cb has color regions G21, G22, G23, G24, G25, and G26. Each of the color regions G11, G12, G21, G22, G23, G24, G25, and G26 is formed of one or more pixels. Here, a pixel is the smallest unit to which the manufacturing device of the display medium 1 can give the same color.

[0031] In the first embodiment, a case where each upper surface cell Cu and each lower surface cell Cb has a color region of the same shape will be described, but the shape may be different for each upper surface cell Cu or lower surface cell Cb. In the first embodiment, a case where multiple color regions are provided in the X-axis direction in each of the upper surface layer Lu and the lower surface layer Lb will be described, but one color region may be provided. In addition, a case where one color region is provided in the Y-axis direction will be described, but multiple color regions may be provided. Furthermore, a case where multiple color regions are provided adjacent to each other will be described, but multiple color regions may be provided discretely, such as by providing a transparent region between the multiple color regions.

[0032] With reference to FIG. 5, the upper cell Cu and the lower cell Cb forming one cell will be described. In the first embodiment, each of the upper cell Cu and the lower cell Cb has a color region and a transparent region to which no color is given. The color region is provided at a position away from the edge of each of the upper cell Cu and the lower cell Cb. The transparent region is a portion not hatched in FIG. 5. A transparent region is provided at the boundary portion of each of the upper cell Cu and the lower cell Cb. A color region is provided in a portion inside the transparent region. By providing the transparent region, it is possible to form the color region so that light passing through the color region does not pass through the color region of the adjacent cell, thereby reducing the burden of calculation of the color to be assigned to each color region. The color region is formed by applying ink to each layer. The ink may be a dye ink or a pigment ink. One color region is formed by one or a plurality of pixels. In the present disclosure, one color is uniformly given within one color region G11. The same is true for the other color regions G12 to G26.

[0033] The positions of the top cell Cu and the bottom cell Cb are set so that in one cell, light passing through the color region of the top cell Cu passes through the bottom cell Cb, and light passing through the color region of the bottom cell Cb passes through the top cell Cu. In the first embodiment, a case is described in which the top cell Cu and the bottom cell Cb included in one cell are shifted in the Z-axis direction, but this is not limited to this. The corresponding top cell Cu and the bottom cell Cb may be shifted in an oblique direction, specifically, not only in the Z-axis direction but also in the X-axis direction or the Y-axis direction.

[0034] In the first embodiment, the cells are formed such that when viewed from each of the first to third directions, the color region of the bottom cell Cb overlaps with the color region of the top cell Cu in different portions. This allows the cells to display different colors in the first to third directions. Here, different from each other means not completely identical, and includes not only completely different colors, but also colors that are at least partially the same and partially different.

[0035] For example, in the first direction of Fig. 5(a), the color regions G11 and G12 of the top cell Cu overlap with the color regions G23 and G24 of the bottom cell Cb. In the second direction of Fig. 5(b), the color regions G11 and G12 of the top cell Cu overlap with the color regions G25 and G26 of the bottom cell Cb. In the third direction of Fig. 5(c), the color regions G11 and G12 of the top cell Cu overlap with the color regions G21 and G22 of the bottom cell Cb.

[0036] In the example shown in Fig. 5, the color region of the bottom cell Cb does not completely overlap with the color region of the top cell Cu in the first to third directions, but they may overlap partially. For example, in another embodiment, the color regions G23 and G24 may overlap with the color region of the top cell Cu in the first direction. The color regions G24 and G25 may overlap with the color region of the top cell Cu in the second direction, and the color regions G22 and G23 may overlap with the color region of the top cell Cu in the third direction.

[0037] In addition, when the ink used in the color region is a highly transparent ink such as a dye ink, the user can visually recognize a color obtained by mixing the colors of the overlapping color regions at each viewpoint in each viewing direction. In FIG. 5(a), the user visually recognizes a color obtained by mixing the colors of G11 and G23, and a color obtained by mixing the colors of G12 and G24. Furthermore, the user visually recognizes a color obtained by mixing the colors of G11 and G23, a color obtained by mixing the colors of G12 and G24, and a color obtained by mixing the colors of G21, G22, G25, and G26 due to juxtaposition additive color mixing.

[0038] On the other hand, if the ink used in the color region is a low-transparency ink such as a pigment ink, the user can see the color close to the viewpoint in the viewing direction. In Fig. 5(a), the user sees the color G11 and the color G12. Furthermore, the user sees a mixture of G11 and G12 and the colors G21, G22, G25, and G26 due to juxtaposition additive color mixing.

[0039] In this way, in each cell of the display medium 1 according to the first embodiment, the portions of the color region of the bottom cell Cb that overlap with the color region of the top cell Cu differ in the first, second and third directions, and therefore different contents can be displayed in the three directions.

[0040] Specifically, the display medium 1 displays reference content D in a first direction. The display medium 1 displays first converted content Ja, which has the same composition as the reference content D but has been color-converted, in a second direction. The display medium 1 displays second converted content Jb, which has the same composition as the reference content D but has been color-converted, in a third direction.

[0041] In the first embodiment, the user alternates between a viewpoint on the display medium 1 from which the reference content D is visible, a viewpoint from which the first converted content Ja is visible, and a viewpoint from which the second converted content Jb is visible. Specifically, the user changes the viewpoint from directly above the display medium 1 to a diagonally upward-left direction and a diagonally upward-right direction. This allows the user to view the content decorated with a rich variety of colors.

[0042] (Processing device) 6, a processing device 10 that determines the color to be applied to the display medium 1 will be described. The processing device 10 assigns a color to each pixel in a color region in the display medium 1 having a plurality of pixels, and generates manufacturing data 13 for producing the display medium 1.

[0043] The processing device 10 includes each of the data, i.e., reference data 11, conversion data 12, manufacturing data 13, cell color data 31, condition data 32, and shape data 33, and each of the functions of an acquisition unit 21, a conversion unit 22, and a generation unit 23. Each of the data is stored in a storage device, such as a memory 902 or a storage 903. Each of the functions is implemented in a CPU 901.

[0044] The reference data 11 is image data that is the basis of the reference content displayed by the display medium 1. The reference data 11 has a plurality of pixels, and each pixel is associated with a predetermined color. The reference data 11 corresponds to the reference content D.

[0045] The converted data 12 is data obtained by converting the colors of the reference data 11 while maintaining the same composition. Although only one converted data 12 is shown in FIG.

[0046] The manufacturing data 13 is data for manufacturing the display medium 1 that displays the reference content D corresponding to the reference data 11 in a first direction and displays the converted content J corresponding to the converted data 12 in a second direction. In the first embodiment, the manufacturing data 13 may be data for manufacturing each of the upper layer Lu and the lower layer Lb. The display medium 1 is manufactured by overlapping the upper layer Lu and the lower layer Lb.

[0047] The manufacturing data 13 is data that specifies the structure and color of the display medium 1. When the display medium 1 is manufactured by printing with a printer, the manufacturing data 13 is data that is input to the printer. In the first embodiment, the manufacturing data 13 associates the position and color of printing on the transparent member. In the example shown in FIG. 5, the manufacturing data 13 associates the color to be given to each of the color areas G11, G12, G21, G22, G23, G24, G25, and G26 for each cell. The manufacturing data 13 further specifies the position where the marker Vu is provided on the upper layer Lu and the position where the marker Vb is provided on the lower layer Lb.

[0048] The cell color data 31 is data on the color to be expressed in each cell of the display medium 1. The cell color data 31 is provided for each direction in which the display medium 1 displays content. In the first embodiment, the cell color data 31 associates the color to be expressed in each cell with the reference content D, the first converted content Ja, and the second converted content Jb displayed in the first to third directions, respectively.

[0049] The condition data 32 is data that specifies the azimuth angle and elevation angle at which the content is displayed on the display medium 1.

[0050] The shape data 33 specifies the position and size of each cell and each pixel of the display medium 1. The shape data 33 specifies, for example, the position and size of the upper surface cells Cu arranged on the upper surface layer Lu of the display medium 1, the position and size of each lower surface cell Cb arranged on the lower surface layer Lb, and the position and size of each pixel.

[0051] The acquisition unit 21 acquires the reference data 11. The acquisition unit 21 may acquire the reference data 11 from, for example, the user terminal 2 or the like via a communication network, or may acquire the reference data 11 from a storage medium or the like accessible by the processing device 10.

[0052] The conversion unit 22 converts the reference data 11 into converted data 12 that has the same composition but has converted colors. When the display medium 1 displays three or more contents, the conversion unit 22 generates converted data 12 whose number is the number of contents displayed by the display medium 1 minus 1 as the content corresponding to the reference data 11.

[0053] The conversion unit 22 uses a predetermined function to convert the color of each pixel of the reference data 11 into the color of each pixel of the converted data 12. For example, a case will be described in which the color of each pixel of the reference data 11 is specified by three elements of R (red), G (green), and B (blue), and the conversion unit 22 generates two converted data 12.

[0054] The conversion unit 22 converts the R value of each pixel of the reference data 11 into the B value of each pixel of the first conversion data 12a, converts the G value of each pixel of the reference data 11 into the R value of each pixel of the first conversion data 12a, and converts the B value of each pixel of the reference data 11 into the G value of each pixel of the first conversion data 12a to generate the first conversion data 12a. The conversion unit 22 also converts the R value of each pixel of the reference data 11 into the G value of each pixel of the second conversion data 12b, converts the G value of each pixel of the reference data 11 into the B value of each pixel of the second conversion data 12b, and converts the B value of each pixel of the reference data 11 into the R value of each pixel of the second conversion data 12b to generate the second conversion data 12b.

[0055] Through this process, the processing device 10 can obtain three image data with different colors.

[0056] The conversion data 12 may be generated by other methods. For example, the conversion unit 22 may convert each RGB value of each pixel into a color space of HSV (hue, saturation, chroma, value, brightness) system and change each value. The conversion unit 22 may change the hue value of each pixel by adding or subtracting a predetermined value to the hue value, thereby generating the conversion data 12.

[0057] Once the reference data 11 and the converted data 12 are identified, manufacturing data 13 is generated. A generating unit 23 generates the manufacturing data 13 for manufacturing a display medium 1 that displays reference content D corresponding to the reference data 11 in a first orientation and converted content J corresponding to the converted data 12 in a second orientation.

[0058] The generation unit 23 generates manufacturing data 13 for manufacturing a display medium 1 that displays reference content D corresponding to the reference data 11 in a first orientation and that displays converted content J corresponding to the converted data 12 in a second orientation. The generation unit 23 includes a calculation unit 36 ​​and an allocation unit 37.

[0059] The calculation unit 36 ​​calculates each RGB value of the color to be displayed in each cell for the content to be displayed in each direction. When the display medium 1 displays a reference content D corresponding to the reference data 11 and two converted contents J corresponding to the two converted data 12, the calculation unit 36 ​​calculates the color to be expressed in each cell for the reference data 11 and the two converted data 12. The calculation unit 36 ​​divides the reference data 11 into sections of each cell of the display medium 1, and specifies the color to be expressed in each cell of the reference data 11. The two converted data 12 are processed in the same manner.

[0060] The allocation unit 37 allocates colors to each pixel of the upper surface cell Cu and the lower surface cell Cb so that, for each cell, the reference content D corresponding to the reference data 11 is displayed in the first direction, and the converted content J corresponding to the converted data 12 is displayed in the second direction. When the display medium 1 displays three contents, the allocation unit 37 allocates colors to each pixel of the upper surface cell Cu and the lower surface cell Cb so that, for each cell, the reference content D corresponding to the reference data 11 is displayed in the first direction, the first converted content Ja corresponding to the first converted data 12a is displayed in the second direction, and the second converted content Jb corresponding to the second converted data 12b is displayed in the third direction.

[0061] The allocation unit 37 searches for a color of each pixel, for example, such that a combination of pixels seen from a first direction achieves a color corresponding to the first direction in the cell color data 31, a combination of pixels seen from a second direction achieves a color corresponding to the second direction in the cell color data 31, and a combination of pixels seen from a third direction achieves a color corresponding to the third direction in the cell color data 31. The allocation unit 37 may search by exhaustive search or by optimization. For example, the allocation unit 37 sets, as a target, an RGB value to be displayed in the first direction, an RGB value to be displayed in the second direction, and an RGB value to be displayed in the third direction. The allocation unit 37 sets, as an evaluation function, a difference between the target and the RGB value to be displayed in the first direction, the RGB value to be displayed in the second direction, and the RGB value to be displayed in the third direction, which are realized by the color of each pixel found by the search. The allocation unit 37 determines a color to be assigned to each pixel so that the evaluation function is minimized.

[0062] At this time, the allocation unit 37 refers to the condition data 32 and the shape data 33 as the specifications of the display medium 1 .

[0063] The allocation unit 37 may further provide markers Vu and Vb on the upper layer Lu and the lower layer Lb, respectively, so that the markers Vu and Vb provided on the upper layer Lu and the lower layer Lb, respectively, overlap when the display medium 1 displays the reference content D in the first direction and the converted content J in the second direction. The shapes of the markers Vu and Vb are preferably shapes that can specify the front and back and orientation of each layer, and further the arrangement position of the upper surface or the lower surface. The marker Vu provided on the upper layer Lu and the marker Vb provided on the lower layer Lb may have some common parts and some different parts, and the upper layer Lu or the lower layer Lb may be distinguished by different parts of each marker. The user may distinguish the upper layer Lu from the lower layer Lb from the different parts of the markers Vu and Vb, and may manufacture the display medium 1 by overlapping the upper layer Lu on the lower layer Lb so that the common parts overlap.

[0064] After determining the color to be assigned to each pixel in each cell, the assignment unit 37 outputs the manufacturing data 13.

[0065] With reference to FIG. 7, a processing method according to the present disclosure will be described.

[0066] First, in step S1, the user terminal 2 transmits the reference data 11 to the processing device 10. The processing device 10 acquires the reference data 11.

[0067] In step S2, the processing device 10 generates converted data 12 from the reference data 11. In step S3, the processing device 10 generates manufacturing data 13 for the display medium 1 for displaying the reference content D corresponding to the reference data 11 and the converted content J corresponding to the converted data 12 in different directions.

[0068] In step S4, the processing device 10 transmits the manufacturing data 13 to the user terminal 2. Upon acquiring the manufacturing data 13, the user terminal 2 manufactures the display medium 1 from the manufacturing data 13 in step S5. Specifically, the user inputs the manufacturing data 13 into a printing machine to print the upper surface layer Lu and the lower surface layer Lb. The user can manufacture the display medium 1 by overlaying the upper surface layer Lu on the lower surface layer Lb.

[0069] The display medium 1 according to the first embodiment can display content with the same composition but different colors in different directions. By changing the direction of the display medium 1 with respect to the user, the display medium 1 can display content decorated with a variety of colors to the user.

[0070] Moreover, the processing device 10 according to the first embodiment can generate manufacturing data 13 for manufacturing the display medium 1 from any reference data acquired from the user terminal 2 or the like, and transmit the manufacturing data 13 to the user terminal 2. This enables the display medium 1 to display any content, such as a drawing by a child, as content decorated with a variety of colors.

[0071] (Second embodiment) In the first embodiment, a case has been described in which a display medium is formed using the technique described in Patent Document 3. In the second embodiment, a case has been described in which a display medium 100 is formed using the technique described in Patent Document 2.

[0072] The display medium 100 according to the second embodiment displays a content decorated with a variety of colors. The display medium 100 displays three contents corresponding to three azimuth angles from a predetermined elevation angle and azimuth angle. The three contents are a reference content D corresponding to the reference data 11, and two converted contents J that have the same composition as the reference data 11 but have been color-converted.

[0073] As shown in FIG. 8, in the second embodiment, the display medium 100 has a plurality of cells C on the surface. As shown in FIG. 9, the cell C has a protruding member having a light-shielding property and a color region on the surface. The cell C is formed so that the color regions viewed are different when viewed from each of the first to third directions different from each other. Here, different color regions means that they are not completely the same, and includes not only the case where they are completely different, but also the case where they are at least partially the same and partially different. The display medium 100 displays a reference content D in a first direction in a portion of each cell viewed from a first viewpoint in a first direction. The reference content D is formed in each pixel of each cell viewed from the first viewpoint. The display medium 100 displays a first converted content Ja in a second direction in a portion of each cell viewed from a second viewpoint in a second direction. The first converted content Ja is formed in each pixel of each cell viewed from the second viewpoint. The display medium 100 displays the second converted content Jb in the third direction in a portion of each cell viewed from a third viewpoint in the third direction. The second converted content Jb is formed in each pixel of each cell viewed from the third viewpoint.

[0074] As shown in Fig. 8, the display medium 100 includes a substrate 101 and a coloring portion 102 that expresses the color of the content on the upper surface of the substrate 101. The substrate 101 has a surface that reflects light. The substrate 101 may be in the form of a thin sheet such as paper, or may be in a three-dimensional shape. The upper surface of the substrate 101 may be flat or curved.

[0075] The upper surface of the base material 101 is divided into a plurality of cells C. The plurality of cells C may be disposed adjacent to each other or may be disposed apart from each other.

[0076] As shown in Fig. 9, one cell C includes a plurality of subcells K0, K1, and K2. Protruding members T0, T1, and T2 are formed in each of the subcells K0, K1, and K2 corresponding to a predetermined azimuth angle. Protruding member T0 is formed in subcell K0. Protruding member T1 is formed in subcell K1. Protruding member T2 is formed in subcell K2.

[0077] The protruding members T0, T1, and T2 are formed of a material that blocks light. The protruding members T0, T1, and T2 have a surface in a predetermined azimuth direction, more specifically, a surface parallel to the azimuth angle corresponding to the subcell in which the protruding member is formed.

[0078] This allows the colored portion of the subcell corresponding to the specified azimuth angle to be observed from a specified elevation angle and azimuth angle.

[0079] For example, when a user observes a certain coordinate on the display medium 100 at a predetermined elevation angle ω0 and azimuth angle φ0, the color value of the coordinate of the first content corresponding to the coordinate can be confirmed. Similarly, when the user observes the coordinate at a predetermined elevation angle ω1 and azimuth angle φ1, the color value of the coordinate of the second content different from the first content corresponding to the coordinate can be confirmed. Furthermore, when the user observes the coordinate at a predetermined elevation angle ω2 and azimuth angle φ2, the color value of the coordinate of the third content different from the first content and the second content corresponding to the coordinate can be confirmed. Note that the elevation angles ω0, ω1, and ω2 may be the same elevation angle with respect to the display medium 100, or may be different elevation angles from each other, although they are not shown in FIG. 9.

[0080] In the second embodiment, a case will be described in which the reference content D is displayed at an azimuth angle φ0, the first converted content Ja is displayed at an azimuth angle φ2, and the second converted content Jb is displayed at an azimuth angle φ3 as shown in Fig. 9, but the present invention is not limited to this. The correspondence between the azimuth angles and the contents to be displayed is determined appropriately.

[0081] With reference to FIG. 9, cell C at coordinate x will be described. Cell C includes subcells K0, K1, and K2. Subcell K0 corresponds to azimuth angle φ0. Subcell K1 corresponds to azimuth angle φ1. Subcell K2 corresponds to azimuth angle φ2. Three protruding members T0 parallel to the direction of azimuth angle φ0 are arranged in subcell K0. Two protruding members T1 parallel to the direction of azimuth angle φ1 are arranged in subcell K1. Three protruding members T2 parallel to the direction of azimuth angle φ2 are arranged in subcell K2.

[0082] Since the protruding member T has a predetermined height, when the display medium 1 is observed from a certain elevation angle, some parts are shielded by the protruding member T and some parts are not shielded on the surface of the display medium 100. When observed from an azimuth angle φ0, the user can see the colored portion 102 of the subcell K0 where the protruding member T0 parallel to the azimuth angle φ0 is formed, but it is difficult to see the colored portion 102 of the other subcells K1 or K2. When observed from an azimuth angle φ1, the user can see the colored portion 102 of the subcell K1 where the protruding member T1 parallel to the azimuth angle φ1 is formed, but it is difficult to see the colored portion 102 of the other subcells K0 or K2. When observed from an azimuth angle φ2, the user can see the colored portion 102 of the subcell K2 where the protruding member T2 parallel to the azimuth angle φ2 is formed, but it is difficult to see the colored portion 102 of the other subcells K0 or K1.

[0083] Such a display medium 100 according to the second embodiment can display three different contents in three different directions. The display medium 100 can display a reference content D at a first viewpoint on an azimuth angle φ0, in pixels that are visible from the first viewpoint. The display medium 100 can display a first converted content Ja at a second viewpoint on an azimuth angle φ1, in pixels that are visible from the second viewpoint. The display medium 100 can display a second converted content Jb at a third viewpoint on an azimuth angle φ2, in pixels that are visible from the third viewpoint.

[0084] In the second embodiment, when viewed from a specific azimuth angle, it is ideal for a user to be able to see each pixel of the colored portion 102 of the sub-cell that corresponds to that azimuth angle, but not be able to see each pixel of the colored portion 102 of the sub-cell that does not correspond to that azimuth angle; however, this may not always be the case.

[0085] FIG. 10 is a diagram for explaining an example of pixels that are shielded and pixels that are exposed in the display medium 100. As shown in FIG. 10, consider a case where a protruding member T1 is formed in a subcell K1. When a user observes from a direction of an azimuth angle φ1 parallel to the protruding member T1, almost all pixels in the subcell K1 can be confirmed. However, a shielding portion K1a is formed, which is a pixel that is not observed even though it is arranged in the subcell K1. Also, an exposed portion K2b may be formed, which is a pixel that is observed even though it is arranged in a subcell K2 that does not correspond to the azimuth angle φ1. Therefore, in the processing of the allocation unit 37 described later, a pixel group that is visible for each viewpoint is specified, and a color is assigned to the specified pixel group so that it is displayed at that viewpoint.

[0086] Next, processing device 10, which assigns colors to each pixel of display medium 100, will be described.

[0087] The processing apparatus 10 according to the second embodiment has a similar configuration to the processing apparatus 10 according to the first embodiment described with reference to FIG.

[0088] In the second embodiment, the manufacturing data 13 associates the position and shape of the protruding member T formed on the surface of the base material 101 with the position and color of printing on the surface of the base material 101. The manufacturing device is, for example, a 3D printer or the like that is also capable of forming the protruding member T.

[0089] In the second embodiment, the condition data 32 is data that specifies the azimuth angle and elevation angle at which content is displayed on the display medium 100. The shape data 33 specifies the position and shape of each cell and each sub-cell on the display medium 100, the position and shape of the protruding member T arranged in each sub-cell, and the like.

[0090] The allocation unit 37 allocates colors to each pixel in the cell to be processed so that pixels seen from a first viewpoint in the cell to be processed display the color of the position of the cell to be processed in the converted content J, pixels seen from a second viewpoint in the cell to be processed display the color of the position of the cell to be processed in the first converted content Ja, and pixels seen from a third viewpoint in the cell to be processed display the color of the position of the cell to be processed in the second converted content Jb. The pixels to be allocated colors here are those in the cell to be processed where no protruding member is formed.

[0091] The allocation unit 37 identifies, among the pixels in the cell to be processed, a group of pixels that are visible from a first viewpoint, a group of pixels that are visible from a second viewpoint, and a group of pixels that are visible from a third viewpoint. For example, in the example of Fig. 10, the pixels that are visible when viewed from the azimuth angle φ1 include the exposed portion K2b in the subcell K2, but do not include the occluded portion K1a in the subcell K1.

[0092] The allocation unit 37 allocates a predetermined color to each pixel in each pixel group so that the color to be displayed in each direction can be expressed in the cell to be processed.

[0093] The processing device 10 repeats the process of assigning a color to each pixel for each cell, and outputs the correspondence between the pixel and the color in each cell to the manufacturing data 13. The manufacturing data 13 also includes the position and shape of the protruding member T specified by the shape data 33. By inputting the manufacturing data 13 to a manufacturing device such as a printer, the display medium 100 in which each pixel is colored with an appropriate color is output.

[0094] Like the display medium 1 according to the first embodiment, the display medium 100 according to the second embodiment can display to the user content decorated with a variety of colors.

[0095] (Technology A) A display medium capable of displaying two contents corresponding to a predetermined elevation angle and two azimuth angles, the display medium comprising: A substrate that reflects light is provided, Dividing the substrate into a plurality of cells; Dividing each of the plurality of cells into three subcells corresponding to each of the two azimuth angles; A protruding member having a surface in a direction of the predetermined azimuth angle that blocks light is formed in each subcell corresponding to the predetermined azimuth angle; From the predetermined elevation and azimuth angles, a subcell corresponding to the predetermined azimuth angle is observed; A reference content is displayed in pixels that are visible from a first viewpoint among the plurality of pixels, and a converted content that has the same composition as the reference content but has a converted color is displayed in pixels that are visible from a second viewpoint among the plurality of pixels. Display medium.

[0096] (Technology B) A processing device for assigning a color to each pixel of a display medium according to the technology A, the display medium comprises a plurality of cells; An acquisition unit that acquires reference data; a conversion unit that converts the reference data into conversion data having the same composition but converted colors; a calculation unit for calculating each color to be displayed in a predetermined cell based on the reference data and the converted data; Displaying the color calculated for the reference data at the pixel in the predetermined cell that is visible from the first viewpoint; displaying the calculated color for the transformed content at pixels in the given cell that are visible from the second viewpoint; an assignment unit for assigning a color to each pixel in the predetermined cell; a generating unit for generating manufacturing data for manufacturing a display medium that displays the color assigned by the assigning unit; A processing device comprising:

[0097] (Third embodiment) 11 is a perspective view of a display medium 200 according to the third embodiment. In the first embodiment, a case where the display medium is formed using the technique described in Patent Document 3 is described. In the third embodiment, a case where the display medium 200 is formed using the technique described in Patent Document 4 is described.

[0098] The display medium 200 according to the third embodiment is a content decorated with a variety of colors. The display medium 200 displays three contents corresponding to three azimuth angles from a given elevation angle and azimuth angle.

[0099] In the third embodiment, a display medium 200 has a plurality of cells C on its surface. The cells C are provided with partitions that radially divide the space on the cells C into three directions and have color regions. The cells C are formed so that the color regions viewed are different when viewed from each of the first to third directions. Here, different color regions means that they are not completely the same, and includes not only cases where they are completely different, but also cases where they are at least partially the same and partially different. The display medium 200 displays a reference content D in a first direction in a portion of each cell viewed from a first viewpoint in a first direction. The reference content D is formed in each pixel of each cell viewed from the first viewpoint. The display medium 200 displays a first converted content Ja in a second direction in a portion of each cell viewed from a second viewpoint in a second direction. The first converted content Ja is formed in each pixel of each cell viewed from the second viewpoint. The display medium 200 displays the second converted content Jb in a third direction in a portion of each cell viewed from a third viewpoint in the third direction. The second converted content Jb is formed in each pixel of each cell viewed from the third viewpoint.

[0100] 11, the display medium 200 includes a substrate 201. The substrate 201 may be in the form of a thin sheet such as paper, or may be in a three-dimensional shape. The upper surface of the substrate 201 may be flat or curved.

[0101] The upper surface of the base material 101 is divided into a plurality of cells C. The plurality of cells may be disposed adjacent to each other or may be disposed separately from each other.

[0102] Fig. 12(a) is a front view of a partition P used in the display medium 200. Fig. 12(b) is a right side view of the partition P. One partition P is provided for one cell C. The partition P is a surface formed on a plane intersecting with the base material 201, and has a portion that is exposed when the display medium 200 is observed from each of three directions. The partition P has a plurality of pixels on its surface.

[0103] 13 is a cross-sectional view of a partition P used in the display medium 200. As shown in FIG. 13, the partition P is formed so as to radially divide the space on the cell C into three directions from a point CS on the cell C. In the third embodiment, the partition P divides the space on the display medium 200 into a first viewpoint, a second viewpoint, and a third viewpoint on the X-axis above the display medium 200. The partition P may be provided so as to be in contact with the outer edge of the cell C and not to be connected to the partition of an adjacent cell. Alternatively, the partition P may be provided so as to be connected to the partition of an adjacent cell C.

[0104] The skeleton of the partition P is a part of a Voronoi surface in a Voronoi diagram having points virtually set in each of the three directions as generating points.

[0105] The partition P has a surface having a plurality of pixels. The display medium 200 displays reference content D at pixels among the plurality of pixels that are visible from a first viewpoint. The display medium 200 displays first converted content Ja at pixels among the plurality of pixels that are visible from a second viewpoint. The display medium 200 displays second converted content Jb at pixels among the plurality of pixels that are visible from a third viewpoint.

[0106] The shape of partition P will be described with reference to Fig. 13. In the third embodiment, a Voronoi diagram for a mother point virtually provided in the direction in which the content is displayed is virtually formed. Partition P includes a Voronoi surface in the Voronoi diagram in its skeleton. Partition P is obtained by adding flesh to the skeleton Voronoi surface. The surface of partition P includes a surface parallel to the Voronoi surface.

[0107] In the example shown in Fig. 13, three viewpoints E1, E2, and E3 are provided. Generator points H1, H2, and H3 are provided on the line of sight when viewing the center Cs of cell C from each of the viewpoints E1, E2, and E3. The generator points H1, H2, and H3 are provided on a virtual sphere of a predetermined radius centered on the center Cs of cell C.

[0108] The partition P has two shielding members W1 and W2. The shielding members W1 and W2 divide the space above the cell C in which the partition P is installed into three regions.

[0109] The shielding member W1 has a Voronoi surface Q1 as a skeleton and is fleshed out to a thickness of 1. The shielding member W2 has a Voronoi surface Q2 as a skeleton and is fleshed out to a thickness of 1. The tip of the shielding member W1 is formed into a circle with a radius of 1.

[0110] The shielding member W1 divides the space above the cell C into a space A1 corresponding to the viewpoint E1 and a space A2 corresponding to the viewpoint E2. The shielding member W2 divides the space above the cell C into a space A2 corresponding to the viewpoint E2 and a space A3 corresponding to the viewpoint E2.

[0111] A portion of the surface of the partition P that is exposed when the display medium 200 is observed from a predetermined specified direction among the three directions has a portion that is blocked when the display medium 200 is observed from a direction other than the predetermined specified direction among the three specified directions. Even if a pixel F on the surface of the partition P is exposed in one or more of the three directions, it may not be visible from the other specified directions. The surface of the partition P expresses the color of the content corresponding to the direction in which it is exposed. This enables the display medium 200 to express parts of different contents in multiple specified directions, making it possible to display multiple contents with a wide color gamut and high brightness.

[0112] 13, the surface of shielding member W1 on the space A1 side is visible from viewpoint E1, but has a portion that cannot be seen from viewpoint E2 or viewpoint E3. The surface of shielding member W1 on the space A2 side is visible from viewpoint E2, but has a portion that cannot be seen from viewpoint E1 or viewpoint E3. The surface of shielding member W2 on the space A2 side is visible from viewpoint E2, but has a portion that cannot be seen from viewpoint E1 or viewpoint E3. The surface of shielding member W2 on the space A3 side is visible from viewpoint E3, but has a portion that cannot be seen from viewpoint E1 or viewpoint E2.

[0113] Each surface of the partition P is formed to be easily visible from one of three directions, and difficult to see from the other two directions. Each surface of the partition P has both the effect of emitting a color that forms content in one direction and the effect of blocking from other directions. This allows the display medium 200 to display different content in three directions. The display medium 200 can also display content with a wide color gamut and high brightness in three directions. Since the influence of the line of sight from directions other than the specified direction is suppressed for each surface of the partition P, a suitable color can be given to the surface observed from the specified direction.

[0114] Next, a description will be given of a processing device that assigns colors to each pixel of the display medium 200. The processing device has a configuration similar to that of the processing device 10 according to the first embodiment shown in FIG.

[0115] In the third embodiment, the manufacturing data 13 associates the position and shape of the partition P to be formed on the surface of the base material 201 with the position and color to be printed on the surface of the partition P. The manufacturing device is, for example, a 3D printer or the like that is also capable of forming the partition P.

[0116] In the third embodiment, the condition data 32 is data that specifies the azimuth angle and elevation angle at which content is displayed on the display medium 200. The shape data 33 specifies the position, shape, etc. of each cell and each partition P on the display medium 200.

[0117] The processing of the allocation unit 37 in the third embodiment is similar to the processing of the allocation unit 37 in the second embodiment.

[0118] The processing device 10 repeats the process of assigning a color to each pixel for each cell, and outputs the correspondence between the pixels and the colors in each cell to the manufacturing data 13. The manufacturing data 13 is input to a manufacturing device such as a printer, and the display medium 200 in which each pixel is colored with an appropriate color is output.

[0119] The display medium 200 according to the third embodiment, like the display medium according to the first or second embodiment, can display to the user content decorated with a variety of colors.
