[0035] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In the drawings, the same symbols are used to refer to the same parts and descriptions are omitted.

[0036] (Display medium)

[0037] The display medium 1 of the embodiments of this disclosure is capable of displaying content with varied decorations. Figure 1 This diagram illustrates an example of the content displayed on display medium 1. Display medium 1 displays an image with a decoration in which the colors of the specified content change sequentially. The user viewing display medium 1 sees the colors of the specified content, such as structural colors or multicolors, or as if a shiny decoration is applied. In this disclosure, content includes images, such as still images, moving images, and moving images with sound.

[0038] like Figure 1 As shown, display medium 1 displays reference content D in the first direction D1, first transformed content Ja in the second direction D2, and second transformed content Jb in the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are mutually different directions. The first transformed content Ja and the second transformed content Jb are content where the reference content D has been color-changed in the same compositional manner. The first transformed content Ja and the second transformed content Jb have the same composition and hue. The first transformed content Ja and the second transformed content Jb change color using mutually different methods. When not specifically distinguishing between the first transformed content Ja and the second transformed content Jb, they are sometimes simply referred to as transformed content J.

[0039] Display medium 1 displays three pieces of content with the same composition but different colors in different directions. The user views display medium 1 by changing their relative viewpoint. The user can change their viewpoint relative to display medium 1 and can also move display medium 1. Display medium 1 can display content with sequentially varying colors within a common composition, thus enabling the display of content with rich color variations.

[0040] exist Figure 1 The example shown illustrates the case where display medium 1 displays one base content D and two transformation content J in three directions, but it is not limited to this. Display medium 1 may display multiple contents with the same composition but different colors in each of two or more directions. Display medium 1 may also not display the base content D, but instead display two or more transformation content J with the same composition as the base content D but different colors.

[0041] (First Implementation)

[0042] Reference Figure 2 The display medium 1 of the first embodiment will be described. The display medium 1 of the first embodiment has the structure of the display medium described in Patent Document 3. Figure 2 As shown, the display medium 1 has a substrate 201. The substrate 201 can be a thin sheet such as paper, or it can be a three-dimensional shape. The upper surface of the substrate 201 can be flat or curved. Figure 2 As shown, display medium 1 has multiple units C on its surface. Figure 2 In the example shown, the user's viewpoint is above the Z-axis (thickness direction). Figure 2 In the example shown, display medium 1 has a cuboid shape, but the shape is not limited.

[0043] like Figure 3 As shown, the display medium 1 has an upper surface layer Lu and a lower surface layer Lb. The names of the upper surface layer Lu and the lower surface layer Lb are independent of the direction of gravity and do not depend on the configuration of the display medium 1. In the first embodiment, the layer closer to the user's viewpoint is called the upper surface layer Lu. The layer farther from the user's viewpoint is called the lower surface layer Lb.

[0044] like Figure 3 and Figure 4As shown, the upper surface layer Lu and the lower surface layer Lb are formed in the XY plane and arranged parallel to the Z-axis direction. The display medium 1 displays multiple contents corresponding to multiple directions based on the portions of the upper surface layer Lu and the lower surface layer Lb through which light from multiple directions passes. Each content is visually recognized from various viewpoints located at the incident positions of the light from the multiple directions passing through the upper surface layer Lu and the lower surface layer Lb. The display medium 1 displays multiple contents because the color combination of the portions passing through the upper surface layer Lu and the portions passing through the lower surface layer Lb differs in each direction. The display medium 1 displays contents from three different viewpoints above the upper surface layer Lu and the lower surface layer Lb in the Z-axis direction. The values ​​(coordinates) in at least the X-axis direction and the Y-axis direction are different for each of the three different viewpoints.

[0045] In the first embodiment, light used in a predetermined direction when displaying content is emitted from at least the upper surface layer Lu and the lower surface layer Lb in a direction opposite to the viewpoint. If the viewpoint is positioned above the upper surface layer Lu and the lower surface layer Lb in the Z-axis direction, light can be emitted from a position below the upper surface layer Lu and the lower surface layer Lb in the Z-axis direction; the position of the light source is not limited. Light emitted upwards from a position below the lower surface layer Lb in the Z-axis direction can be, for example, light reflected from a light source located at any position and then transmitted through the substrate M, or light from a light source located on the substrate M. Alternatively, it can be light irradiated from a light source (not shown) located on the back side of the substrate M and transmitted through the substrate M.

[0046] like Figure 3 As shown, a transparent layer N is formed between the upper surface layer Lu and the lower surface layer Lb. Furthermore, a substrate M is disposed in the opposite direction to the transparent layer N and the Z-axis direction relative to the lower surface layer Lb. In the Z-axis direction, these components are stacked in the order of substrate M, lower surface layer Lb, transparent layer N, and upper surface layer Lu to form the display medium 1.

[0047] The transparent layer N is preferably formed of a material that does not absorb light (visible light) but allows a large amount of light to pass through. For example, the transparent layer N is formed of a transparent material such as water or transparent plastic. The transparent layer N can also be formed from air. In other words, the upper surface layer Lu and the lower surface layer Lb can be arranged parallel to each other at a predetermined distance. The substrate M is a mirror, white paper, or the like, and is formed of a component whose color is easily visually recognizable for the upper surface layer Lu and the lower surface layer Lb.

[0048] like Figure 3 and Figure 4As shown, the upper surface layer Lu is formed of a transparent component and has multiple upper surface units Cu. Each of the multiple upper surface units Cu has a color gamut. The lower surface layer Lb is formed of a transparent component and has multiple lower surface units Cb. Each of the multiple lower surface units Cb has a color gamut. By defining the positions of the upper surface units Cu and the lower surface units Cb, a printing press or similar device that assigns color to the color gamuts of the upper surface units Cu and the lower surface units Cb can determine the position of each color gamut, and the positions of the upper surface units Cu and the lower surface units Cb may not be visually discernible. For example, there may be no clear lines, gaps, recesses, or other separations between two adjacent upper surface units Cu or two lower surface units Cb. Two adjacent upper surface units Cu or two lower surface units Cb may not be physically separated. Furthermore, at the boundary between two adjacent upper surface units Cu or two adjacent lower surface units Cb, since the ends of the two units are given the same color or the same colorless color, the adjacent units C may not be visually discernible.

[0049] In the first embodiment, each upper surface unit Cu of the upper surface layer Lu and each lower surface unit Cb of the lower surface layer Lb are formed to separate the layers in the same way. That is, each upper surface unit Cu of the upper surface layer Lu is formed at a position that keeps the positions of each lower surface unit Cb of the lower surface layer Lb unchanged in the X-axis and Y-axis directions but offset in the Z-axis direction. More specifically, as Figure 4 As shown, in an embodiment of the present invention, the upper surface unit Cu of the upper surface layer Lu is formed at a position that offsets the lower surface unit Cb of the lower surface layer Lb in the Z-axis direction. The same applies to other units. In the first embodiment, the relationship between units such as the upper surface unit Cu and the lower surface unit Cb, formed at positions offset in the Z-axis direction, is referred to as "correspondence." Furthermore, in the first embodiment, the case where the corresponding upper surface unit Cb and lower surface unit Cb are at the same position in the X-axis and Y-axis directions, and differ only in the Z-axis direction, is described, but is not limited to this. As another embodiment, the corresponding upper surface unit Cb and lower surface unit Cb may also be offset in the X-axis or Y-axis directions in addition to the Z-axis direction.

[0050] In the first embodiment, unit C includes an upper surface unit Cu of the upper surface layer Lu and a lower surface unit Cb of the lower surface layer Lb that overlaps (corresponds to) the upper surface unit Cu. Unit C is determined by the combination of corresponding upper surface units Cu and lower surface units Cb of each upper surface unit Cu of the upper surface layer Lu and each lower surface unit Cb of the lower surface layer Lb.

[0051] like Figure 4As shown, in the first embodiment, marks Vu and Vb are respectively provided on the upper surface layer Lu and the lower surface layer Lb. When the display medium 1 is formed by overlapping two transparent components, and the two transparent components overlap appropriately, the marks Vu and Vb provided on the two transparent components overlap. Here, in this disclosure, appropriate overlap refers to the case where the upper surface layer Lu and the lower surface layer Lb overlap according to the design of the display medium 1. Specifically, appropriate overlap occurs when the reference content D is displayed in the first direction and the transformation content J is displayed in the second direction.

[0052] In this disclosure, the case where the markings Vu and Vb overlap to indicate the overlapping position of the upper surface layer Lu and the lower surface layer Lb is described, but it is not limited thereto. The markings Vu and Vb are sufficient to indicate the position where the upper surface layer Lu and the lower surface layer Lb appropriately overlap.

[0053] like Figures 3 to 5 As shown, the upper surface layer Lu is formed of a transparent component and has multiple upper surface units Cu. The multiple upper surface units Cu each have color gamuts G11 and G12. The lower surface layer Lb is formed of a transparent component and has multiple lower surface units Cb. The multiple lower surface units Cb each have color gamuts G21, G22, G23, G24, G25, and G26. Color gamuts G11, G12, G21, G22, G23, G24, G25, and G26 are each formed by one or more pixels. Here, a pixel is the smallest unit of color assigned by the manufacturing apparatus of display medium 1.

[0054] In the first embodiment, the case where each upper surface unit Cu and each lower surface unit Cb has a color gamut of the same shape is described, but the shape may differ depending on the upper surface unit Cu or the lower surface unit Cb. Furthermore, in the first embodiment, the case where multiple color gamuts are provided in the X-axis direction in each of the upper surface layer Lu and the lower surface layer Lb is described, but a single color gamut may also be provided. Additionally, the case where a single color gamut is provided in the Y-axis direction is described, but multiple color gamuts may also be provided. Furthermore, the case where multiple color gamuts are provided adjacent to each other is described, but multiple color gamuts may also be provided discretely, such as by providing transparent areas between them.

[0055] Reference Figure 5 The upper surface unit Cu and the lower surface unit Cb forming a single unit will be described. In the first embodiment, the upper surface unit Cu and the lower surface unit Cb each have a color gamut and a transparent region that is not colored. The color gamut is located away from the ends of each unit of the upper surface unit Cu and the lower surface unit Cb. The transparent region is... Figure 5There are no shaded areas. Transparent regions are provided at the boundaries between the upper surface unit Cu and the lower surface unit Cb. A color gamut is provided at a position inside the transparent regions. By providing transparent regions, it is possible to form a color gamut where light passing through the gamut does not pass through adjacent units, thus reducing the computational burden of assigning colors to each color gamut. The color gamut is formed by coating ink onto each layer. The ink can be dye ink or pigment ink. A color gamut is formed by one or more pixels. In this disclosure, a single color is uniformly assigned within a color gamut G11. The same applies to the other color gamuts G12 to G26.

[0056] In a single unit, the positions of the upper surface unit Cu and the lower surface unit Cb are set such that light passing through the color gamut of the upper surface unit Cu passes through the lower surface unit Cb, and light passing through the color gamut of the lower surface unit Cb passes through the upper surface unit Cu. In the first embodiment, the case where the upper surface unit Cu and the lower surface unit Cb contained in a single unit are offset in the Z-axis direction is described, but it is not limited to this. The corresponding upper surface unit Cu and lower surface unit Cb may also be offset in the tilt direction; specifically, they may be offset not only in the Z-axis direction but also in the X-axis direction or the Y-axis direction.

[0057] In the first embodiment, when visually recognized from each of the first to third directions, the unit is formed such that the overlapping portions of the color gamuts of the upper surface unit Cu within the color gamut of the lower surface unit Cb are different from each other. Thus, the unit can display different colors in the first to third directions. Here, "different from each other" means not completely identical, including not only cases of complete difference but also cases where at least some parts are the same and some parts are different.

[0058] For example, in Figure 5 In the first direction of (a), the color gamuts G11 and G12 of the upper surface unit Cu overlap with the color gamuts G23 and G24 of the lower surface unit Cb. Figure 5 In the second direction of (b), the color gamuts G11 and G12 of the upper surface unit Cu overlap with the color gamuts G25 and G26 of the lower surface unit Cb. Figure 5 (c) upwards, the color gamuts G11 and G12 of the upper surface unit Cu overlap with the color gamuts G21 and G22 of the lower surface unit Cb.

[0059] exist Figure 5In the example shown, the case where the overlapping portions of the color gamut of the lower surface unit Cb and the color gamut of the upper surface unit Cu are completely non-overlapping in the first to third directions is illustrated, but partial overlap is also possible. For example, in other embodiments, color gamuts G23 and G24 overlap with the color gamut of the upper surface unit Cu in the first direction. Alternatively, color gamuts G24 and G25 may overlap with the color gamut of the upper surface unit Cu in the second direction, and color gamuts G22 and G23 may overlap with the color gamut of the upper surface unit Cu in the third direction.

[0060] Furthermore, when the ink used in the color gamut is a highly transparent ink such as a dye ink, the user can visually distinguish the colors formed by mixing the various colors of the overlapping color gamut at each viewpoint in each direction of visual recognition. Figure 5 In (a), the user visually identifies the color formed by mixing the colors of G11 and G23, and the color formed by mixing the colors of G12 and G24. Furthermore, the user visually identifies the color formed by mixing the colors of G11 and G23, the color formed by mixing the colors of G12 and G24, and the color formed by mixing the colors of G21, G22, G25, and G26 through additive color mixing.

[0061] On the other hand, when the ink used in the color gamut is a low-transmittance ink such as pigment ink, the user can visually distinguish colors close to the viewpoint in the direction of visual recognition. Figure 5 In (a), the user visually identifies the colors of G11 and G12. Furthermore, the user visually identifies the colors formed by mixing G11 and G12 with the colors of G21, G22, G25, and G26 through juxtaposition and additive color mixing.

[0062] In this way, for each unit of the display medium 1 in the first embodiment, the overlapping portion of the color gamut of the lower surface unit Cb and the color gamut of the upper surface unit Cu is different with respect to the first direction, the second direction and the third direction, so that different content can be displayed in the three directions.

[0063] Specifically, display medium 1 displays reference content D in a first direction. Display medium 1 displays first transformed content Ja in a second direction, with the same composition as reference content D but different colors. In a third direction, it displays second transformed content Jb, with the same composition as reference content D but different colors.

[0064] In the first embodiment, the user alternately changes their viewpoint relative to the display medium 1 between a viewpoint where they can see the base content D, a viewpoint where they can see the first transformed content Ja, and a viewpoint where they can see the second transformed content Jb. Specifically, the user changes their viewpoint relative to the display medium 1 to directly above, slightly above the left, and slightly above the right. This allows the user to visually recognize content with color-changing decorations.

[0065] (Processing device)

[0066] Reference Figure 6 The processing apparatus 10, which determines the color assigned to the display medium 1, will be described. In the display medium 1 having multiple pixels, the processing apparatus 10 assigns a color to each pixel in the color gamut and generates manufacturing data 13 for generating the display medium 1.

[0067] The processing device 10 includes reference data 11, transformation data 12, manufacturing data 13, unit color data 31, condition data 32, and shape data 33, as well as the functions of an acquisition unit 21, a transformation unit 22, and a generation unit 23. All data are stored in a storage device such as a memory 902 or a recorder 903. Each function is implemented by a CPU 901.

[0068] Reference data 11 is data of an image that serves as the source of reference content displayed on display medium 1. Reference data 11 has multiple pixels, and a defined color is associated with each pixel. Reference data 11 corresponds to reference content D.

[0069] Transformed data 12 is data whose colors have been changed in the same manner as the base data 11. Figure 6 In this context, there can be only one transformation data 12, but there can also be multiple transformation data 12. Transformation data 12 corresponds to transformation content J.

[0070] Manufacturing data 13 is data used to manufacture a display medium 1 that displays reference content D corresponding to reference data 11 in a first direction and transformation content J corresponding to transformation data 12 in a second direction. In a first embodiment, manufacturing data 13 may be data used to manufacture each of the upper surface layer Lu and the lower surface layer Lb. The display medium 1 is manufactured by overlapping the upper surface layer Lu and the lower surface layer Lb.

[0071] Manufacturing data 13 is data that determines the structure and color of the display medium 1. When the display medium 1 is manufactured by printing on a printing press, manufacturing data 13 is data input into the printing press. In the first embodiment, manufacturing data 13 associates the printing positions of transparent components with colors. Figure 5In the example shown, manufacturing data 13, on a unit basis, maps the colors assigned to each color gamut of color gamuts G11, G12, G21, G22, G23, G24, G25, and G26. Manufacturing data 13 also determines the positions of marker Vu in the upper surface layer Lu and marker Vb in the lower surface layer Lb.

[0072] The unit color data 31 is data on the colors that should be represented by each unit of the display medium 1. The unit color data 31 is set according to the orientation of the content displayed on the display medium 1. In the first embodiment, the unit color data 31 corresponds to the colors that should be represented by each unit for each of the reference content D, the first transformation content Ja, and the second transformation content Jb displayed in the first to third directions, respectively.

[0073] Condition data 32 is data that determines the azimuth and elevation angles of the content to be displayed on display medium 1.

[0074] Shape data 33 determines the position and size of each unit and each pixel of the display medium 1. Shape data 33, for example, determines the position and size of the upper surface unit Cu disposed on the upper surface layer Lu of the display medium 1, the position and size of each lower surface unit Cb disposed on the lower surface layer Lb, and the position and size of each pixel, etc.

[0075] The acquisition unit 21 acquires the reference data 11. For example, the acquisition unit 21 can acquire the reference data 11 from the user terminal 2 or the like via a communication network, or it can acquire the reference data 11 from a storage medium or the like that accessible by the processing device 10.

[0076] The transformation unit 22 transforms the reference data 11 into transformation data 12, which changes the color in the same way as the composition. When the display medium 1 displays more than three contents, the transformation unit 22 generates transformation data 12 of the number of contents displayed on the display medium 1 minus 1 as the contents corresponding to the reference data 11.

[0077] The transformation unit 22 uses a predetermined function to transform the color of each pixel in the reference data 11 to the color of each pixel in the transformation data 12. For example, the case where the color of each pixel in the reference data 11 is determined by three factors: R (red), G (green), and B (blue), and the transformation unit 22 generates two transformation data 12 will be explained.

[0078] The transformation unit 22 transforms the R value of each pixel in the reference data 11 to the B value of each pixel in the first transformation data 12a, transforms the G value of each pixel in the reference data 11 to the R value of each pixel in the first transformation data 12a, and transforms the B value of each pixel in the reference data 11 to the G value of each pixel in the first transformation data 12a, thereby generating the first transformation data 12a. Furthermore, the transformation unit 22 transforms the R value of each pixel in the reference data 11 to the G value of each pixel in the second transformation data 12b, transforms the G value of each pixel in the reference data 11 to the B value of each pixel in the second transformation data 12b, and transforms the B value of each pixel in the reference data 11 to the R value of each pixel in the second transformation data 12b, thereby generating the second transformation data 12b.

[0079] Through this process, the processing device 10 can obtain three image data with different colors.

[0080] Transformation data 12 can also be generated by other methods. For example, transformation unit 22 can also transform the RGB values ​​of each pixel into the HSV (Hue, Saturation, Chroma, Value, Brightness) color space to change the values. Transformation unit 22 can also change the hue value of each pixel by adding or subtracting a predetermined value to generate transformation data 12.

[0081] When the reference data 11 and the transformation data 12 are determined, manufacturing data 13 is generated. The generation unit 23 generates manufacturing data 13 for manufacturing the display medium 1, which displays reference content D corresponding to the reference data 11 in a first direction and transformation content J corresponding to the transformation data 12 in a second direction.

[0082] The generation unit 23 generates manufacturing data 13 for manufacturing the display medium 1, which displays reference content D corresponding to reference data 11 in a first direction and transformation content J corresponding to transformation data 12 in a second direction. The generation unit 23 includes a calculation unit 36 ​​and an allocation unit 37.

[0083] The calculation unit 36 ​​calculates the RGB values ​​of the colors displayed in each unit for the content displayed in each direction. When the display medium 1 displays reference content D corresponding to reference data 11 and two transformation contents J corresponding to two transformation data 12, the calculation unit 36 ​​calculates the colors represented by each unit for the reference data 11 and the two transformation data 12. The calculation unit 36 ​​divides the reference data 11 into distinctions for each unit of the display medium 1 and determines the colors represented by the reference data 11 in each unit. The two transformation data 12 are processed in the same way.

[0084] The allocation unit 37 assigns colors to each pixel of the upper surface unit Cu and the lower surface unit Cb for each unit in a manner that displays reference content D corresponding to reference data 11 in a first direction and transformation content J corresponding to transformation data 12 in a second direction. When the display medium 1 displays three contents, the allocation unit 37 assigns colors to each pixel of the upper surface unit Cu and the lower surface unit Cb for each unit in a manner that displays reference content D corresponding to reference data 11 in a first direction, first transformation content Ja corresponding to first transformation data 12a in a second direction, and second transformation content Jb corresponding to second transformation data 12b in a third direction.

[0085] For example, the allocation unit 37 searches for the color of each pixel in the unit color data 31 that corresponds to the color in the first direction as seen from the first direction, the color in the unit color data 31 that corresponds to the color in the second direction as seen from the second direction, and the color in the unit color data 31 that corresponds to the color in the third direction as seen from the third direction, for each unit. The allocation unit 37 can perform the search cyclically or by optimization. The allocation unit 37 sets the RGB values ​​displayed in the first direction, the RGB values ​​displayed in the second direction, and the RGB values ​​displayed in the third direction as targets, for example. The allocation unit 37 sets the difference between the RGB values ​​displayed in the first direction, the RGB values ​​displayed in the second direction, and the RGB values ​​displayed in the third direction as achieved by the searched colors of each pixel and the target as an evaluation function. The allocation unit 37 determines the color to be allocated to each pixel in a manner that minimizes the evaluation function.

[0086] At this time, the distribution unit 37 refers to the condition data 32 and shape data 33 as the specifications of the display medium 1.

[0087] The distribution unit 37 may also, when displaying reference content D in the first direction and transformation content J in the second direction on the display medium 1, provide markings Vu and Vb on each of the upper surface layer Lu and the lower surface layer Lb in an overlapping manner. The shapes of the markings Vu and Vb are preferably those that can determine the surface and orientation of each layer, as well as the placement position of the upper or lower surface. The markings Vu on the upper surface layer Lu and Vb on the lower surface layer Lb may share a common portion and differ in another portion; the difference in the markings can distinguish between the upper surface layer Lu and the lower surface layer Lb. The user can distinguish the upper surface layer Lu and the lower surface layer Lb based on the different portions of the markings Vu and Vb, and superimpose the upper surface layer Lu onto the lower surface layer Lb by overlapping the common portions to manufacture the display medium 1.

[0088] When the allocation unit 37 determines the color of each pixel to be allocated to each unit, it outputs manufacturing data 13.

[0089] Reference Figure 7 The processing method disclosed herein shall be explained.

[0090] First, in step S1, the user terminal 2 sends the reference data 11 to the processing device 10. The processing device 10 then obtains the reference data 11.

[0091] In step S2, the processing device 10 generates transformation data 12 based on the reference data 11. In step S3, the processing device 10 generates manufacturing data 13 for the display medium 1 that displays the reference content D corresponding to the reference data 11 and the transformation content J corresponding to the transformation data 12 in different directions.

[0092] In step S4, the processing device 10 sends manufacturing data 13 to the user terminal 2. Upon receiving the manufacturing data 13, the user terminal 2 manufactures the display medium 1 according to the manufacturing data 13 in step S5. Specifically, the user inputs the manufacturing data 13 into a printing press to print the upper surface layer Lu and the lower surface layer Lb. The user can manufacture the display medium 1 by superimposing the upper surface layer Lu onto the lower surface layer Lb.

[0093] The display medium 1 of the first embodiment can display content with the same composition but different colors in different directions. By changing the orientation of the display medium 1 relative to the user, the display medium 1 can display content decorated with rich color variations to the user.

[0094] Furthermore, the processing apparatus 10 of the first embodiment can generate manufacturing data 13 for manufacturing the display medium 1 based on arbitrary reference data obtained from the user terminal 2, etc., and send it to the user terminal 2. Thus, the display medium 1 can display arbitrary content, such as a child's drawing, as content with rich color variations.

[0095] (Second Implementation)

[0096] In the first embodiment, the case of forming a display medium using the technology described in Patent Document 3 was described. In the second embodiment, the case of forming a display medium 100 using the technology described in Patent Document 2 was described.

[0097] The display medium 100 of the second embodiment displays content decorated with rich color variations. The display medium 100 displays three contents corresponding to three azimuth angles, based on a predetermined elevation angle and azimuth angle. The three contents are: reference content D corresponding to reference data 11, and two modified contents J with the same composition as reference data 11 but with changed colors.

[0098] like Figure 8 As shown, in the second embodiment, the display medium 100 has a plurality of units C on its surface. For example... Figure 9 As shown, unit C is a light-shielding protruding component with a color gamut on its surface. Unit C is formed such that the color gamut perceived by the viewer differs when viewed from each of the first to third mutually different directions. Here, "different color gamut" means not completely identical, including cases where at least some parts are the same and some parts are different, in addition to cases where they are completely identical. The display medium 100 displays reference content D in the first direction through portions of each unit viewed from a first viewpoint in the first direction. The reference content D is formed by each pixel of each unit viewed from the first viewpoint. The display medium 100 displays first transformation content Ja in the second direction through portions of each unit viewed from a second viewpoint in the second direction. The first transformation content Ja is formed by each pixel of each unit viewed from the second viewpoint. The display medium 100 displays second transformation content Jb in the third-third-direction through portions of each unit viewed from a third viewpoint in the third-third-direction. The second transformation content Jb is formed by each pixel of each unit viewed from the third viewpoint.

[0099] like Figure 8 As shown, the display medium 100 has a substrate 101 and a coloring portion 102 that displays the color of the content on the upper surface of the substrate 101. The substrate 101 has a light-reflecting surface. The substrate 101 can be a sheet shape such as paper, or it can be a three-dimensional shape. The upper surface of the substrate 101 can be a flat surface or a curved surface.

[0100] The upper surface of the substrate 101 is divided into multiple units C. The multiple units C can be arranged adjacent to each other or separated from each other.

[0101] like Figure 9 As shown, a single element C has multiple sub-elements K0, K1, and K2. Protruding components T0, T1, and T2 are formed in each of the sub-elements K0, K1, and K2 corresponding to a specified azimuth angle, respectively. Protruding component T0 is formed in sub-element K0. Protruding component T1 is formed in sub-element K1. Protruding component T2 is formed in sub-element K2.

[0102] The protruding components T0, T1, and T2 are formed by light-shielding components. The protruding components T0, T1, and T2 have a surface with a defined azimuth direction, and more specifically, a surface parallel to the azimuth of the sub-unit on which the protruding component is formed.

[0103] Therefore, the colored part of the sub-unit corresponding to the specified azimuth angle is observed from the specified elevation angle and azimuth angle.

[0104] For example, when a user observes a certain coordinate on the display medium 100 with a specified elevation angle ω0 and azimuth angle φ0, the color value of the coordinate of the first content corresponding to that coordinate can be determined. Similarly, when a user observes that coordinate with a specified elevation angle ω1 and azimuth angle φ1, the color value of the coordinate of the second content, which is different from the first content, corresponding to that coordinate can be determined. Furthermore, when a user observes that coordinate with a specified elevation angle ω2 and azimuth angle φ2, the color value of the coordinate of the third content, which is different from both the first and second content, corresponding to that coordinate can be determined. Moreover, the elevation angles ω0, ω1, and ω2 are... Figure 9 Although not shown in the figure, the elevation angle relative to the display medium 100 can be the same or different.

[0105] In the second embodiment, for the Figure 9 The example shown illustrates a scenario where azimuth angle φ0 displays the reference content D, azimuth angle φ2 displays the first transformed content Ja, and azimuth angle φ3 displays the second transformed content Jb, but this is not the only possible interpretation. The correspondence between azimuth angles and the displayed content should be appropriately determined.

[0106] Reference Figure 9 The element C at coordinate x is described below. Element C has three sub-elements: K0, K1, and K2. Sub-element K0 corresponds to azimuth angle φ0. Sub-element K1 corresponds to azimuth angle φ1. Sub-element K2 corresponds to azimuth angle φ2. Three protruding components T0 parallel to the direction of azimuth angle φ0 are arranged in sub-element K0. Two protruding components T1 parallel to the direction of azimuth angle φ1 are arranged in sub-element K1. Three protruding components T2 parallel to the direction of azimuth angle φ2 are arranged in sub-element K2.

[0107] The protruding member T has a predetermined height. Therefore, when viewing the display medium 1 from a certain elevation angle, the surface of the display medium 100 shows portions obscured by the protruding member T and portions not obscured. When viewed from an azimuth angle φ0, the user can visually identify the colored portion 102 of the subunit K0 formed by the protruding member T0 parallel to the azimuth angle φ0, but it is difficult to visually identify the colored portions 102 of other subunits K1 or K2. Similarly, when viewed from an azimuth angle φ1, the user can visually identify the colored portion 102 of the subunit K1 formed by the protruding member T1 parallel to the azimuth angle φ0, but it is difficult to visually identify the colored portions 102 of other subunits K0 or K2. Furthermore, when viewed from an azimuth angle φ2, the user can visually identify the colored portion 102 of the subunit K2 formed by the protruding member T2 parallel to the azimuth angle φ2, but it is difficult to visually identify the colored portions 102 of other subunits K0 or K1.

[0108] The display medium 100 of this second embodiment can display three different contents in three different directions. The display medium 100 can display the reference content D from a first viewpoint at azimuth angle φ0 using pixels seen from the first viewpoint. The display medium 100 can display the first transformed content Ja from a second viewpoint at azimuth angle φ1 using pixels seen from the second viewpoint. The display medium 100 can display the second transformed content Jb from a third viewpoint at azimuth angle φ2 using pixels seen from the third viewpoint.

[0109] Furthermore, in the second embodiment, when a user views from a predetermined azimuth angle, they can confirm each pixel of the shading portion 102 of the sub-unit corresponding to that azimuth angle, but they cannot confirm that each pixel of the shading portion 102 of the sub-unit not corresponding to that azimuth angle is ideal, although this is not always the case.

[0110] Figure 10 This diagram illustrates an example of pixels that are hidden and pixels that are exposed in the display medium 100. For example... Figure 10 As shown, consider the case where a protruding member T1 is formed in subunit K1. When viewed from an azimuth angle φ1 parallel to the protruding member T1, the user can confirm approximately all the pixels within subunit K1. However, pixels that are not observed despite being located within subunit K1, i.e., occluded portions K1a, are formed. Additionally, pixels that are observed despite being located in subunit K2, which does not correspond to azimuth angle φ1, i.e., exposed portions K2b, are sometimes formed. Therefore, in the processing of the allocation unit 37 described later, a group of pixels seen at a viewpoint is determined, and colors are assigned to this determined group of pixels for display at that viewpoint.

[0111] Next, the processing apparatus 10 that assigns colors to each pixel of the display medium 100 will be described.

[0112] The processing apparatus 10 of the second embodiment has a reference... Figure 6 The processing device 10 described in the first embodiment has the same structure.

[0113] In the second embodiment, the manufacturing data 13 corresponds the position and shape of the protruding member T formed relative to the surface of the substrate 101, and the position and color of the printing relative to the surface of the substrate 101. The manufacturing apparatus is, for example, a 3D printer capable of forming the protruding member T.

[0114] In the second embodiment, condition data 32 is data that determines the azimuth and elevation angles of the content displayed in the display medium 100. Shape data 33 determines the position and shape of each unit and subunit in the display medium 100, the position and shape of the protruding member T disposed in each subunit, etc.

[0115] The allocation unit 37 assigns colors to each pixel within the processing object unit in such a manner that the color of the position of the processing object unit in the transformation content J is displayed through pixels within the processing object unit viewed from a first viewpoint, the color of the position of the processing object unit in the first transformation content J1 is displayed through pixels within the processing object unit viewed from a second viewpoint, and the color of the position of the processing object unit in the second transformation content Jb is displayed through pixels within the processing object unit viewed from a third viewpoint. Here, the pixels that are assigned colors are those pixels within the processing object unit that do not have protruding members.

[0116] The allocation unit 37 determines, respectively, the pixel group seen from the first viewpoint, the pixel group seen from the second viewpoint, and the pixel group seen from the third viewpoint within the unit of the processing object. For example, in Figure 10 In the example, the pixel seen when viewed from the azimuth angle φ1 includes the exposed portion K2b within subunit K2, but does not include the occluded portion K1a within subunit K1.

[0117] The allocation unit 37 allocates a specified color to each pixel in a manner that allows the processing object's unit to represent the color to be displayed in each direction through each pixel group.

[0118] The processing device 10 repeatedly performs color assignment processing on each pixel in each unit, and outputs the correspondence between pixels and colors in each unit to the manufacturing data 13. Furthermore, the manufacturing data 13 includes the position and shape of the protruding member T determined by the shape data 33. By inputting the manufacturing data 13 into a manufacturing apparatus such as a printing press, a display medium 100 in which each pixel is colored with an appropriate color is output.

[0119] The display medium 100 of the second embodiment is the same as the display medium 1 of the first embodiment, and can display content with rich color variations to the user.

[0120] (Technology A)

[0121] A display medium, relative to a predetermined elevation angle and two azimuth angles, is capable of displaying two contents corresponding to the two azimuth angles, wherein,

[0122] The display medium has a light-reflecting substrate.

[0123] The aforementioned substrate is divided into multiple units.

[0124] The aforementioned multiple units are each divided into three sub-units corresponding to each of the aforementioned two azimuth angles.

[0125] In each sub-unit corresponding to the specified azimuth angle, a protruding component with a surface that blocks light and has the aforementioned specified azimuth angle direction is formed.

[0126] Observe the sub-unit corresponding to the specified azimuth angle from the above-specified elevation and azimuth angles.

[0127] The baseline content is displayed using pixels seen from the first viewpoint out of a set of pixels, while the transformed content, which has the same composition as the baseline content but with different colors, is displayed using pixels seen from the second viewpoint out of a set of pixels.

[0128] (Technology B)

[0129] A processing apparatus assigns color to each pixel of a display medium as described in technique A, wherein,

[0130] The display medium has multiple units.

[0131] The processing device has:

[0132] The acquisition department obtains benchmark data;

[0133] The transformation unit transforms the reference data into transformed data with the same composition but different colors;

[0134] The calculation unit calculates each color displayed in a specified unit from the reference data and the transformation data;

[0135] An allocation unit assigns colors to each pixel within the defined unit in a manner that displays colors calculated for the reference data through pixels viewed from the first viewpoint within the defined unit, and colors calculated for the transformation content through pixels viewed from the second viewpoint within the defined unit; and...

[0136] The generation unit generates manufacturing data for manufacturing display media that displays colors allocated by the allocation unit.

[0137] (Third implementation method)

[0138] Figure 11 This is a perspective view of the display medium 200 according to the third embodiment. In the first embodiment, the case where the display medium is formed using the technology described in Patent Document 3 was described. In the third embodiment, the case where the display medium 200 is formed using the technology described in Patent Document 4 will be described.

[0139] The display medium 200 in the third embodiment features content decorated with rich color variations. The display medium 200 displays three contents corresponding to three azimuth angles, based on a predetermined elevation angle and azimuth angle.

[0140] In the third embodiment, the surface of the display medium 200 has a plurality of units C. Each unit C has a partition that radially divides the space on the unit C in three directions and has a color gamut. The units C are configured such that the color gamut is different when visually recognized from each of the first to third directions. Here, "different color gamut" means not completely identical; besides completely identical cases, it also includes cases where at least some parts are the same and some parts are different. The display medium 200 displays reference content D in the first direction through portions of each unit viewed from a first viewpoint in the first direction. The reference content D is formed by each pixel of each unit viewed from the first viewpoint. The display medium 200 displays first transformation content Ja in the second direction through portions of each unit viewed from a second viewpoint in the second direction. The first transformation content Ja is formed by each pixel of each unit viewed from the second viewpoint. The display medium 200 displays second transformation content Jb in the third-third-direction through portions of each unit viewed from a third-third-direction viewpoint. The second transformation content Jb is formed by each pixel of each unit visible from the third viewpoint.

[0141] like Figure 11 As shown, the display medium 200 has a substrate 201. The substrate 201 can be a thin sheet such as paper, or it can be a three-dimensional shape. The upper surface of the substrate 201 can be a flat surface or a curved surface.

[0142] The upper surface of the substrate 101 is divided into multiple units C. The multiple units can be arranged adjacent to each other or separated from each other.

[0143] Figure 12 (a) is a front view of the partition P used to display medium 200. Figure 12 (b) is a right-side view of the partition P. One partition P is provided in one unit C. The partition P is a surface formed on a plane intersecting the substrate 201, having portions exposed when the display medium 200 is viewed from three directions. The partition P has multiple pixels on its surface.

[0144] Figure 13 This is a cross-sectional view of the partition P used to display medium 200. (Example) Figure 13 As shown, the partition P is formed to radially divide the space on unit C in three directions from point CS on unit C. In the third embodiment, the partition P distinguishes a first viewpoint, a second viewpoint, and a third viewpoint on the X-axis above the display medium 200. The partition P can be configured to be connected to the outer edge of unit C and not connected to the partitions of adjacent units. Alternatively, the partition P can also be configured to be connected to the partitions of adjacent units C.

[0145] The skeleton of partition P is part of the Volonoi surface in the Volonoi diagram, which is virtually set as parent points in each of the three directions.

[0146] The surface of partition P has multiple pixels. Display medium 200 displays reference content D through a pixel seen from a first viewpoint. Display medium 200 displays first transformed content Ja through a pixel seen from a second viewpoint. Display medium 200 displays second transformed content Jb through a pixel seen from a third viewpoint.

[0147] Reference Figure 13 The shape of the partition P will be described. In the third embodiment, a Volonoi diagram is virtually formed with respect to a parent point virtually set in the direction of the displayed content. The partition P includes a Volonoi surface in the Volonoi diagram within the skeleton. The partition P is a thickened partition of the Volonoi surface that forms the skeleton. The surface of the partition P includes surfaces parallel to the Volonoi surface.

[0148] exist Figure 13 In the example shown, three viewpoints E1, E2, and E3 are set. Parent points H1, H2, and H3 are set along the lines of sight when visually recognizing the center Cs of unit C from each viewpoint E1, E2, and E3. Parent points H1, H2, and H3 are set on a virtual sphere of a predetermined radius centered on the center Cs of unit C.

[0149] The partition P has two shielding components W1 and W2. The shielding components W1 and W2 divide the space on the unit C where the partition P is located into three areas.

[0150] The shielding component W1 is based on the Volono surface Q1 and is thickened by a thickness l. The shielding component W2 is based on the Volono surface Q2 and is thickened by a thickness l. In addition, the front end of the shielding component W1 is formed into a circle with a radius l.

[0151] The occlusion component W1 divides the space on unit C into space A1 corresponding to viewpoint E1 and space A2 corresponding to viewpoint E2. The occlusion component W2 divides the space on unit C into space A2 corresponding to viewpoint E2 and space A3 corresponding to viewpoint E2.

[0152] The portion of the surface of the partition P that is exposed when viewing the display medium 200 from one of the three specified directions has a portion that is obscured when viewed from directions other than the three specified directions. Regarding a certain pixel F on the surface of the partition P, even if it is exposed in more than one of the three directions, there may be a situation where it is not visible from other specified directions. The surface of the partition P displays the color of the content corresponding to the exposed direction. Therefore, the display medium 200 can display different portions of content in multiple specified directions, thus enabling the display of multiple contents with a wide color gamut and high brightness.

[0153] For example in Figure 13In the example shown, the surface of the occluding member W1 on the space A1 side has a portion that is visually recognizable from viewpoint E1 but not from viewpoint E2 or viewpoint E3. The surface of the occluding member W1 on the space A2 side has a portion that is visually recognizable from viewpoint E2 but not from viewpoint E1 or viewpoint E3. The surface of the occluding member W2 on the space A2 side has a portion that is visually recognizable from viewpoint E2 but not from viewpoint E1 or viewpoint E3. The surface of the occluding member W2 on the space A3 side has a portion that is visually recognizable from viewpoint E3 but not from viewpoint E1 or viewpoint E2.

[0154] The partition P has surfaces that are easily visible from one of the three directions, but difficult to see from the other two. Each surface of the partition P combines the effect of emitting the color of the content in one direction with the effect of blocking it from other directions. Therefore, the display medium 200 can display different content in three directions. Furthermore, the display medium 200 can display content with a wide color gamut and high brightness in all three directions. Since each surface of the partition P suppresses the influence of viewing from directions other than the specified direction, it is possible to assign appropriate color to the surface viewed from the specified direction.

[0155] Next, the processing apparatus for assigning colors to each pixel of the display medium 200 will be described. The processing apparatus has a... Figure 6 The processing device 10 of the first embodiment shown has the same structure.

[0156] In the third embodiment, the manufacturing data 13 corresponds to the position and shape of the partition P formed relative to the surface of the substrate 201, and the position and color of the printing relative to the surface of the partition P. The manufacturing apparatus is, for example, a 3D printer capable of forming the partition P.

[0157] In the third embodiment, condition data 32 is data that determines the azimuth and elevation angles of the content displayed on the display medium 200. Shape data 33 determines the position and shape of each unit and each partition P in the display medium 200.

[0158] The processing of the distribution unit 37 in the third embodiment is the same as that in the second embodiment.

[0159] The processing device 10 repeatedly performs color assignment processing on each pixel in each unit, and outputs the correspondence between pixels and colors in each unit to the manufacturing data 13. By inputting the manufacturing data 13 into a manufacturing device such as a printing press, a display medium 100 in which each pixel is colored with an appropriate color is output.

[0160] The display medium 200 of the third embodiment is the same as the display medium of the first or second embodiment, and is capable of displaying content with rich color variations to the user.

[0167] The reference content is displayed using the pixels seen from the first viewpoint among the multiple pixels set in the aforementioned partition, and the transformed content, which has the same composition as the reference content but with different colors, is displayed using the pixels seen from the second viewpoint among the multiple pixels.
