[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, in Patent Document 1, the color of the content displayed by the display medium is sometimes affected by the color of the protruding member. For example, in the case where the protruding member is black, the color of the content displayed by the display medium becomes black, and in the case where the protruding member is red, the color of the content becomes red.

[0029] Next, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the drawings, the same or similar parts are labeled with the same or similar reference numerals.

[0030] (Display medium)

[0031] Reference Figure 1 The display medium 1 according to an embodiment of the present invention will be described. The display medium 1 according to an embodiment of the present invention is configured to display a predetermined number of contents corresponding to a predetermined number of azimuth angles from a predetermined elevation angle and an azimuth angle. The display medium 1 can display contents by viewing from a predetermined elevation angle at a predetermined azimuth angle, and can also display different contents by changing the azimuth angle. The display medium 1 can display multiple contents for each predetermined azimuth angle. Furthermore, the elevation angle at which the observer views the contents can also vary for each content. In the embodiment of the present invention, the contents are static images. Additionally, in the embodiment of the present invention, the direction in which the display medium 1 displays the contents is sometimes referred to as a designated direction.

[0032] like Figure 1 As shown in (a), the display medium 1 has a colored portion 4 on the plane of the planar component 2. The planar component 2 has a plane that reflects light. The planar component 2 only needs to be able to perform specular reflection or diffuse light. In addition, from the viewpoint of improving visual recognition, the planar component 2 is preferably formed of a metal with a high specular content. The colored portion 4 is the portion colored with ink.

[0033] like Figure 1 As shown in (a), the plane of planar component 2 is divided into multiple unit elements C. Figure 1 In the example shown, the plane of planar component 2 has multiple unit cells arranged in both the longitudinal and transverse directions. Furthermore, as... Figure 1 As shown in (b), multiple unit cells C are divided into a predetermined number of sub-units B corresponding to a predetermined number of azimuth angles.

[0034] Here, the unit C and sub-unit B can also be virtual divisions. For example, when two adjacent sub-units B are assigned the same color value, or depending on the configuration of the protruding part 3, the boundary of the sub-unit B or unit C may not be visualized.

[0035] In addition, Figure 1 In the example shown, the case where the planar component 2 is a cuboid is explained, but as long as it has a plane, the colored part 4 can be set on that plane. In addition, the case where the unit unit C and the sub-unit B are both rectangles is explained, but the shapes of the unit unit C and the sub-unit B are not limited.

[0036] The number of sub-units B in a unit C corresponds to the amount of content that can be displayed on the display medium 1. For example, inFigure 1 In the example shown, 1 unit cell C is divided into 3 sub-cells B, and thus at least 3 contents can be displayed. Each sub-cell B corresponding to a predetermined azimuth angle of the coloring portion 4 is given a color of each portion corresponding to the predetermined azimuth angle, which constitutes a content.

[0037] As Figure 1 In each sub-cell B, the plate-like protruding member 3 is arranged perpendicular to the planar member 2, as shown in (b) of FIG. 1. Figure 1 In the example shown in (b) of FIG. 1, a case where 2 protruding members 3 are provided in each sub-cell B is described, but 1 protruding member 3 can be provided in each sub-cell B, or 3 or more protruding members 3 can be provided.

[0038] The protruding member 3 has a light-shielding surface parallel to the planar member 2 with respect to a predetermined number of azimuth angles. The protruding member 3 can be formed of an opaque member that shields light, but can also be formed to transmit a portion of light within a range that does not affect visual recognition by an observer. In each sub-cell B corresponding to a predetermined azimuth angle, the protruding member 3 is formed to have a surface parallel to the predetermined azimuth angle.

[0039] In a case where a plurality of protruding members 3 are provided in 1 sub-cell B, the protruding members 3 are arranged parallel to each other. The protruding members 3 are arranged in different directions for each sub-cell B in which the protruding member 3 is provided, and the protruding members 3 arranged in different sub-cells B are arranged non-parallel to each other.

[0040] The display medium 1 of the embodiment of the present application is observed from a predetermined elevation angle. As shown in (b) of FIG. 1, since the plate-like protruding member 3 is arranged perpendicular to the plane of the planar member 2, the coloring portion 4 that is not shielded by the protruding member 3 is confirmed when the display medium 1 is observed from the predetermined elevation angle. Figure 1

[0041] Further, the area ratio of each sub-cell B in the unit cell C and the shape of the protruding member 3 are formed so that at least one or more of (1) the amount of light-shielding by the protruding member 3 with respect to light from a predetermined sub-cell B observed from a predetermined azimuth angle, (2) the amount of light from a direction other than the predetermined direction or a sub-cell B other than the predetermined sub-cell B, and (3) the standard deviation of the reflection luminance of each sub-cell B is reduced. The shape of each sub-cell B and the protruding member 3 is determined by the method described in Patent Document 1.

[0042] Referring to Figure 2 , the elevation angle and the azimuth angle at which the display medium 1 of the embodiment of the present application is observed are described. Figure 2 (a) of FIG. 1 describes a case where contents I0, I1, and I2 are displayed on the display medium 1. ​

[0043] When observing coordinate x on display medium 1 at a predetermined elevation angle ω0 and azimuth angle φ0, the color value of the content I0 corresponding to coordinate x on display medium 1 can be determined. Similarly, when observing coordinate x on display medium 1 at a predetermined elevation angle ω1 and azimuth angle φ1, the color value of the content I1 corresponding to coordinate x on display medium 1 can be determined. Furthermore, when observing coordinate x on display medium 1 at a predetermined elevation angle ω2 and azimuth angle φ2, the color value of the content I2 corresponding to coordinate x on display medium 1 can be determined.

[0044] Figure 1 The unit cell C of the display medium 1 shown in (a) is, for example, Figure 2 It is formed as shown in (b). Unit C comprises subunits B0, B1, and B2. Subunit B0 has three protruding members L0 arranged parallel to the direction of azimuth φ0. Subunit B1 has two protruding members L1 parallel to the direction of azimuth φ1. Subunit B2 has three protruding members L2 parallel to the direction of azimuth φ2.

[0045] exist Figure 2 In the example shown in (b), if unit cell C is viewed from the direction of azimuth angle φ0, the color of the colored portion 4 of sub-unit B0 can be seen, and the protruding member L0 disposed in sub-unit B0, the protruding member L1 disposed in sub-unit B1, and the protruding member L2 disposed in sub-unit B2 can also be seen. Since the protruding member L0 disposed in sub-unit B0 is formed parallel to the azimuth angle φ0, the thickness portion of the protruding member L0 is observed. Therefore, it can be considered that the color of the protruding member L0 has a limited impact on the visual recognizability of the content.

[0046] However, the protruding member L1 located in subunit B1 and the protruding member L2 located in subunit B2 are formed such that their length direction intersects the azimuth angle φ0, thereby obscuring the color of the colored portion 4 of subunit B1 and subunit B2 with a wider surface. When unit unit C is viewed from the direction of azimuth angle φ0, the color of the wider surface of the protruding member L1 and the protruding member L2 has a significant impact on the visual recognizability of the content.

[0047] The same applies when observing unit C from other azimuth angles φ1 and φ2. The wider face of the protruding component, orthogonal to the azimuth angle of observation, has a greater impact on the visual recognizability of the content.

[0048] (First Implementation)

[0049] In the first embodiment, the protruding member 3 is formed in a non-color gray. The protruding member 3 can be formed of a member in gray, or a member in a color other than gray can be colored in gray. The first embodiment is suitable for a display medium 1 capable of forming a member in gray as the protruding member 3. Also, in the embodiments of the present application, the non-color is gray excluding white and black.

[0050] The protruding member 3 can also be colored in a plurality of colors to form a non-color by additive color mixing, or formed by connecting members formed of the plurality of colors. For example, when viewed from a position opposite to the planar member 2, the upper surface of the protruding member is divided into a plurality of regions colored in various colors, in a manner that adjacent regions in the longitudinal direction and the lateral direction are colored in different colors, and adjacent regions in the oblique direction are colored in the same color. When the protruding member 3 is viewed at a very close distance, even in a case where the respective colors can be distinguished to be confirmed, when viewed from a place far enough to visually recognize the content displayed by the display medium 1, it appears to be gray by additive color mixing, specifically, a color having a higher brightness than black.

[0051] Since the protruding member 3 appears to be gray, even if the protruding member 3 is visually recognized, it does not affect the color tone of the content, and thus does not greatly reduce the visual recognizability of the content. Thus, the display medium 1 can be coordinated with any content without limiting the color of the content.

[0052] Also, in the first embodiment, a case where the colo rization by additive color mixing is an example of additive color mixing, but the protruding member 3 can be formed to appear to be gray by additive color mixing other than the additive color mixing by juxtaposition. For example, the protruding member 3 can be formed in gray by additive color mixing by simultaneously irradiating the protruding member 3 with a plurality of colors. Also, in a case where the colorization of the protruding member 3 can be changed by time division, the protruding member 3 can be formed to be recognized as gray in the human brain by successive additive color mixing.

[0053] (Second Embodiment)

[0054] In the first embodiment, a case where a member in gray is formed as the protruding member 3 is described, but in the second embodiment, a case where the protruding member 3 is formed of UV (ultraviolet) curable ink ejected by an inkjet printer is described.

[0055] The inkjet printer scans on the planar member 2 to colorize the colored portion 4, forming the protruding member 3. The inkjet printer colors the colored portion 4 in color values assigned to each subunit calculated by the method described in Patent Document 1. The colored portion 4 is formed of the color of the ink carried by the inkjet printer or the color after mixing the inks.

[0056] In addition, the inkjet printer ejects the UV resin toward the position of the protruding member 3 in a manner having a desired height. When the UV resin is cured, a fine uneven shape of the protruding member 3 is formed on the planar member 2. In addition, the inkjet printer forms the protruding member 3 in a manner having light shielding properties, for example, in a manner having a thickness of 0.005 mm or more.

[0057] In a case where the ink mounted on the inkjet printer is a gray ink, the inkjet printer mixes the UV ink and the gray ink to form the protruding member 3. Thereby, it is possible to form a display medium 1 that is not limited in color tone and can be coordinated with any content.

[0058] However, a general inkjet printer mostly mounts inks of C (cyan), M (magenta), and Y (yellow), and does not mount a gray ink. As a method of forming an intermediate color different from the color of the ink mounted on the inkjet printer such as gray, there are half tone and continuous tone overprint. The half tone is expressed by dithering a pattern or error diffusion, and thus cannot be used for the protruding member in principle. Regarding the continuous tone overprint, when colors are controlled in superposition, there is a case where the height differs depending on the intermediate color, and it is not possible to form a protruding member having a uniform height. Thus, the printer cannot form the protruding member 3 by a general method of forming an intermediate color.

[0059] In the second embodiment, a method of forming a protruding member 3 that can be coordinated with any content using the colors of inks mounted on an inkjet printer such as CMY is described. In the second embodiment, the protruding member 3 is colored in a plurality of colors that form an achromatic color by additive color mixing. Regarding the protruding member 3 thus formed, although each color applied to the protruding member 3 can be confirmed in a relatively close position, the color of the protruding member 3 becomes an achromatic color, specifically, a color having a higher brightness than black, in a position where it can be visually recognized by additive color mixing. Thereby, the color of the protruding member 3 does not affect the color tone of the color of the content.

[0060] The plurality of colors in which the protruding member 3 is colored are the primary colors of the inks used in the inkjet printer, respectively. The respective colors constituting the plurality of colors can be the colors of the inks mounted on the inkjet printer. In the embodiments of the present application, a case where CMY mounted on a general inkjet printer is described. The colors constituting the plurality of colors can also be a combination of other colors such as RGB. When the protruding member 3 is formed by color mixing of the inks mounted on the inkjet printer, the brightness of the protruding member 3 decreases along with the color mixing. Thus, the primary colors of the inks mounted on the inkjet printer are combined, and the protruding member 3 is colored in an achromatic color by additive color mixing, thereby making the height of the protruding member 3 uniform, and further, it is possible to avoid the decrease in the brightness of the protruding member 3 along with the color mixing.

[0061] The inkjet printer does not mix the respective inks mounted thereon and separately ejects each to the adjacent fine regions. Thus, at an extremely close distance at which the colors of the respective inks can be distinguished and visually recognized, the respective colors of CMY can be distinguished, but at a distant position at which additive color mixing can be performed, CMY is mixed and becomes gray. By forming the display medium 1 so that the respective colors of CMY can be distinguished at an extremely close distance, additive color mixing is generated at a position at which the content is visually recognized, and the display medium 1 can be coordinated with any content without limiting the color tone of the content.

[0062] In addition, in the second embodiment, as an example of additive color mixing, a case in which collocation additive color mixing is used is described, but the protruding member 3 can be formed to appear in gray by additive color mixing other than collocation additive color mixing. For example, the protruding member 3 can be formed in gray by simultaneous additive color mixing by which a plurality of colors are overlapped and irradiated to the protruding member 3. In addition, in a case in which coloring of the protruding member 3 can be changed by time division, the protruding member 3 can be formed to be recognized as gray in the human brain by successive additive color mixing.

[0063] When the display medium 1 is observed from a position (upper side) opposite to the planar member 2, the upper surface of the protruding member 3 is divided into a plurality of regions to which various colors are imparted, and the respective regions are imparted with various colors of CMY. When the display medium 1 is observed from the upper surface, the upper surface of each protruding member 3 provided in each unit is divided into a plurality of regions, and each region is colored in the color of the ink mounted on the inkjet printer. The regions divided on the upper surface of the protruding member 3 can be the same or different for each unit C. For example, one color can be imparted in each unit C, one color can be imparted in a plurality of unit Cs, or a plurality of colors can be imparted in one unit C.

[0064] The same color is imparted in the vertical direction from the standing portion of the planar member 2 to the upper surface of the protruding member 3. The respective colors of CMY are only required to make the protruding member 3 appear in gray by additive color mixing at the time of displaying the content, and the arrangement of the respective colors of CMY is not limited.

[0065] For example, there is a method in which the protruding member 3 is divided into a horizontal stripe shape in plan view, and the respective colors of CMY are colored. In this case, the protruding member 3 is divided into a plurality of regions in the horizontal direction, and the respective regions are colored in the respective colors of CMY. The color imparted to the protruding member 3 is colored to the planar member 2 in the vertical direction. Figure 1 (b) of FIG. 1, and Figure 2 In each coordinate system shown in (b) of FIG. 1 and (b) of FIG. 2, the Y-axis direction is divided into a plurality of regions by not dividing the X-axis direction of the protruding member 3, and a plurality of regions in which the X-axis direction is the length direction are formed in the Y-axis direction. Each of the plurality of regions is colored in any one of the colors of CMY. The color imparted to the upper surface of the protruding member 3 is colored to the planar member 2 in the Z-axis direction. Specifically, in the case of (b) of FIG. 1, the protruding member 3 is divided into a plurality of regions in the Y-axis direction, and the respective regions are colored in the respective colors of CMY. The color imparted to the protruding member 3 is colored to the planar member 2 in the Z-axis direction. Figure 2In the example shown in (b), if the YZ plane of the visual recognition unit C is visually recognized from the left side in the X-axis direction, the side surface of the protruding member Ll is colored in longitudinal stripe shape in the order of CMY, and if the XZ plane of the visual recognition unit C is visually recognized from the front side in the Y-axis direction, any one color of CMY is colored to one surface.

[0066] For example, there is a method in which the protruding member 3 is divided into longitudinal stripe shape in plan view, and each color of CMY is colored. In this case, the color of the protruding member 3 is colored to the planar member 2 in the Z-axis direction. Figure 1 In the example shown in (b) of (b) and Figure 2 In each coordinate system shown in (b) of (b) and Figure 1 In the example shown in (a), if the YZ plane of the visual recognition unit C is visually recognized from the left side in the X-axis direction, any one color of CMY is colored to one surface, and if the XZ plane of the visual recognition unit C is visually recognized from the front side in the Y-axis direction, the side surface of the protruding member 3 is colored in longitudinal stripe shape in the order of CMY.

[0067] In addition, there is a method in which the protruding member 3 is divided into inclined stripe shape in plan view, and each color of CMY is colored. In this case, the color of the protruding member 3 is colored to the planar member 2 in the Z-axis direction. Figure 1 In the example shown in (b) of (b) and Figure 2 In each coordinate system shown in (b) of (b) and Figure 1 In the example shown in (a), if the YZ plane of the visual recognition unit C is visually recognized from the left side in the X-axis direction, the side surface of the protruding member 3 is colored in longitudinal stripe shape in the order of CMY, and if the XZ plane of the visual recognition unit C is visually recognized from the front side in the Y-axis direction, the side surface of the protruding member 3 is colored in longitudinal stripe shape in the order of CMY.

[0068] In addition, there is a method in which the protruding member 3 is divided into grid shape in plan view, and each color of CMY is colored. In this case, the color of the protruding member 3 is colored to the coloring portion 4 in the Z-axis direction. Figure 1 In the example shown in (b) of (b) and Figure 2 In each coordinate system shown in (b) of (b) and Figure 1In the example shown in (a), if the YZ plane of the visual recognition unit C is visually recognized from the left side in the X-axis direction, it is colored in vertical stripe patterns in the order of CMY, and if the XZ plane of the visual recognition unit C is visually recognized from the front side in the Y-axis direction, the side surface of the protruding member L is colored in vertical stripe patterns in the order of CMY.

[0069] At this time, as shown in Figure 3 , the protruding member 3 preferably imparts different colors to regions adjacent in the longitudinal direction and the lateral direction, and the same color to regions adjacent in the oblique direction, in plan view. Figure 3 The upper drawing in (a) shows a pattern of colors imparted to the protruding member 3 in plan view of the display medium 1. The lower drawing shows a pattern of colors imparted to the protruding member 3 in side view of the display medium 1. In addition, in Figure 3 and Figure 4 , white represents cyan (C), light gray represents magenta (M), and dark gray represents yellow (Y).

[0070] In the example shown in Figure 3 , the regions of each color of CMY are arranged in the oblique 45-degree direction, and CMY is repeatedly arranged in both the X-axis direction and the Y-axis direction. In the pattern shown in Figure 3 , regardless of which rectangular position is focused on, CMY is arranged adjacent to the surrounding rectangles, and thus if the display medium 1 is confirmed from a position where additive color mixing occurs, an achromatic color is uniformly formed. Figure 3 The pattern shown in is independent of the direction of the protruding member 3, in other words, the direction in which the display medium 1 displays content, and thus can be applied to any display medium 1.

[0071] In the display medium 1, one region obtained by dividing the upper surface of the protruding member 3 in plan view is formed by multiple ejections of an inkjet printer. In general, UV-curable ink is liquid before curing, and thus easily spreads when only one point is ejected alone, and sometimes cannot form a desired height. In addition, in general, if different colors of ink are ejected adjacent to each other, they mix, and have the characteristic of color turbidity, and thus cannot control the color in units of points. In addition, a point is a printed surface formed by one ejection of an inkjet printer.

[0072] Therefore, since each region is formed with multiple points, it is possible to prevent the UV-curable ink from spreading and mixing colors, and to form a protruding member 3 having a desired height with a desired color.

[0073] Furthermore, by forming each region from multiple points, the possibility of color mixing at the boundaries of different colors is taken into account, but the points where color mixing does not occur are ensured to be free of color mixing. For example, when a region is formed by 10 points × 10 points, in the X-axis direction passing through the center of the region, the two points at both ends are adjacent to regions assigned different colors, thus causing color mixing, but color mixing is unlikely to occur at the other 8 points. Although color mixing occurs in the parts where different colors are adjacent, it does not occur in the parts where the same color is adjacent, thus suppressing the decrease in brightness that accompanies color mixing.

[0074] In addition, the number of dots constituting each area is determined in order to achieve the following effects: the effect of UV effect ink not spreading and color not mixing, and the effect of becoming achromatic when additively mixed with the colors in the surrounding areas.

[0075] Furthermore, in the embodiments of the present invention, the division of the color of the upper surface of the protruding member 3 into rectangles when viewed from above the display medium 1 is described, but it is not limited to this. When visually recognizing the content displayed on the display medium 1 from various positions relative to the display medium 1, the protruding member 3 can be achromatic, and the colors do not necessarily have the same shape. The protruding member 3 is preferably colored without omission by any one of the inks carried by the inkjet printer, and each color has the same area. In addition, the case where the combination of achromatic colors is the three colors CMY is described, but it can also be a combination of four or more primary colors of the inks carried by the inkjet printer.

[0076] Reference Figure 4 This illustrates an example of coloring the protruding part 3. Figure 4 In the display medium 1 shown, unit cells C are arranged in a 5×5 configuration, and T-shaped protruding parts 3 are formed in each cell. Figure 4 of (a), Figure 4 (b) and Figure 4 The grain size of the region (rectangular) formed on the upper surface of the protruding member 3 gradually increases in the order of (c). Figure 6 In the image, when viewed from above, areas of the same color are set at a 45-degree angle.

[0077] When viewing the display medium 1 from above, the coarser the grain of each area, the easier it is to see shadows in the same color direction of the area; conversely, the finer the grain, the harder it is to see shadows in the same color direction of the area. The grain of each area can also be determined based on the content displayed on the display medium 1, etc.

[0078] According to the inventors, the display medium 1 of the second embodiment has improved visual recognizability of the content compared to the display medium in which the protruding member 3 is formed in black.

[0079] (Third Implementation)

[0080] The first and second embodiments describe a case where the display medium 1 provided with the colored portion 4 and the protruding portion 3 that appears to be achromatic is formed on the planar member 2, but it can also be implemented in other ways.

[0081] In the third embodiment, as shown in FIG. 9, the display auxiliary medium 11 in which the protruding portion 3 described above is formed on a sheet-shaped member that is sheet-shaped and transmits light is attached to the display surface 13 of a general display device 12 that reflects light. The display device 12 displays an image that determines the color of each sub-unit in accordance with the shape of the unit cell C, the sub-unit B, and the protruding portion 3 formed in the display auxiliary medium 11. In other words, the display device 12 electrically implements the colored portion 4 of the first and second embodiments.

[0082] Thus, as with the embodiments of the present application, different content can be observed from each azimuth. The sheet-shaped member used by the display auxiliary medium 11 can be formed of a transparent member that transmits light, but can also be formed so as to transmit a portion of light within a range that does not affect the visual recognition of the observer. Here, the display device 12 is a liquid crystal display, an organic EL display, or the like, and is preferably a display that uses a bright backlight or uses a bright light emitting element.

[0083] The display auxiliary medium 11 of the third embodiment is suitable for a case where it is desired to display an arbitrary different image depending on the azimuth. The display auxiliary medium 11 can display information corresponding to the position and other conditions of each observer, for example, with respect to a plurality of observers who observe the display auxiliary medium 11 attached to the display device 12 from different directions.

[0084] In the third embodiment, the protruding portion 3 formed on the sheet-shaped member can be formed of gray, as described in the first or second embodiment, or can be colored in a plurality of colors that appear to be achromatic by additive color mixing.

[0085] In addition, when the display auxiliary medium 11 forms the protruding portion 3 on the transparent sheet-shaped member by ejecting UV-cured ink with an inkjet printer, the plurality of colors that are colored on the protruding portion 3 are preferably the primary colors of the ink used in the inkjet printer, respectively. In addition, it is preferable that the upper surface of the protruding portion 3 be divided into a plurality of regions to which various colors are imparted when viewed from a position opposite the sheet-shaped member, different colors are imparted to regions adjacent in the longitudinal direction and the lateral direction, and the same color is imparted to regions adjacent in the oblique direction. Furthermore, these regions are preferably formed by multiple ejections with the inkjet printer.

[0086] The display device 12 is capable of displaying an arbitrary image, and thus is capable of appropriately displaying an image according to an arbitrary condition. In addition, by continuously changing the image by the display device 12, it is possible to observe different dynamic image contents from each azimuth. By pasting the display auxiliary medium 11 in which the protruding member 3 colored in a plurality of colors formed by a gray color or a non-color formed by additive color mixing is formed on such a display device 12, the display auxiliary medium 11 is capable of coordinating with an arbitrary content without affecting the color tone of the content displayed by the display device 12.

[0087] Further, the pixels of the image displayed by the display device 12 correspond to the sub-units formed in the display auxiliary medium 11, and thus the alignment is appropriately performed so that the display auxiliary medium 11 is appropriately pasted to the display surface 13.

[0088] (Process device)

[0089] Reference Figure 6 A process device 100 of an embodiment of the present application will be described. The process device 100 is a general-purpose computer provided with a storage device 110, a process control device 120, and an input / output interface 130. The general-purpose computer realizes the functions illustrated in the drawing by executing a process program. Figure 6

[0090] Figure 3 The process device 100 illustrated in the drawing determines a combination of colors or a disposition of colors when a plurality of colors are combined and the protruding member 3 is colored by additive color mixing. The process device 100 is used for an inkjet printer to manufacture the display medium 1 of the second embodiment or the display auxiliary medium 11 described in the third embodiment.

[0091] The storage device 110 is a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, an SSD (Solid State Drive), or the like, and stores various data such as input data, output data, and intermediate data for the process control device 120 to execute a process. The process control device 120 is a CPU (Central Processing Unit) that reads and writes data stored in the storage device 110 or inputs and outputs data with the input / output interface 130 to execute a process in the process device 100. The input / output interface 130 inputs a result of a process of the process device 100 to an inkjet printer. The inkjet printer forms the protruding member 3 of the display medium 1 with reference to the result obtained from the process device 100.

[0092] ​The storage device 110 stores a processing program, and stores color data 111 and configuration data 112. The color data 111 is data that determines a combination of colors decided by the color deciding section 121, that is, colors of which achromatic colors are formed by additive color mixing. The configuration data 112 is a configuration of colors decided by the configuration deciding section 122, and is data that determines a size of a region in which the same color is configured and a configuration of colors of which achromatic colors are formed by additive color mixing. The processing program can be stored in a computer-readable recording medium such as an HDD, an SSD, a USB (Universal Serial Bus) memory, a CD (Compact Disc), a DVD (Digital Versatile Disc), or the like, or can be distributed via a network.

[0093] The processing control device 120 includes the color deciding section 121, the configuration deciding section 122, and an output section 123.

[0094] The color deciding section 121 decides a combination of colors of which achromatic colors are formed by additive color mixing by the protruding member 3. For example, in a case where the inkjet printer is equipped with each of inks of CMY, the color deciding section 121 decides CMY as the combination of colors of which achromatic colors are formed by additive color mixing. In a case where the inkjet printer is equipped with an ink of another color, the color deciding section 121 decides a combination of primary colors of an ink that the inkjet printer can be equipped with, that is, a combination of colors of which achromatic colors are formed by additive color mixing.

[0095] The color deciding section 121 outputs the decided combination of colors as the color data 111.

[0096] The configuration deciding section 122 decides a configuration of colors of which achromatic colors are formed by additive color mixing so that the protruding member 3 appears to be achromatic. The configuration deciding section 122 decides a size of a region in which one color is formed on the upper surface of the protruding member 3. In a case where the size of the region is large, an influence of color mixing of colors of adjacent portions of the region is small, and on the other hand, a shadow of connection of colors imparted to the region is easily seen, and in a case where the size of the region is small, an influence of color mixing of colors of adjacent portions of the region is large, and on the other hand, a shadow of connection of colors imparted to the region is difficult to see. The configuration deciding section 122 can also decide the size of the region in which one color is formed depending on content to be displayed.

[0097] The configuration deciding section 122 also decides colors of each region. The configuration deciding section 122 decides a configuration of each color of which achromatic colors are formed by additive color mixing in a manner that becomes a predetermined shape such as a vertical stripe shape or a horizontal stripe shape when viewed from above. The configuration deciding section 122 decides a configuration of each color of which achromatic colors are formed by additive color mixing in a manner that, for example, as shown in FIG. 2, a region in which a color of the protruding member 3 is formed is formed in a vertical stripe shape when viewed from above. Figure 7The manner of giving different colors to regions adjacent in the longitudinal direction and the lateral direction and giving the same color to regions adjacent in the oblique direction determines the disposition of the colors forming the achromatic color by additive color mixing.

[0098] The disposition determining section 122 outputs the disposition of the regions of the same color and the disposition of the colors forming the achromatic color by additive color mixing as the disposition data 112.

[0099] The output section 123 inputs data for enabling the inkjet printer to form the protruding member 3 to the inkjet printer. The output section 123 outputs the color data 111 output by the color determining section 121 or the disposition data output by the disposition determining section 122. The output section 123 can also output the color data 111 output by the color determining section 121 and the disposition data 112 output by the disposition determining section 122.

[0100] Reference Figure 1 The processing method of the processing device 100 will be described.

[0101] First, in step S1, the processing device 100 determines the combination of the colors forming the achromatic color. In step S2, the processing device 100 determines the disposition of the colors coloring the protruding member 3 with respect to the combination of the colors determined in step S1. In step S3, the processing device 100 outputs the disposition of the colors determined in step S2 to the inkjet printer.

[0102] Such a processing device 100 can output data for manufacturing the display medium 1 related to the second embodiment or the display auxiliary medium 11 described in the third embodiment.

[0103] In addition, the case where the color data 111 and the disposition data 112 generated by the processing device 100 are input to the inkjet printer is described, but is not limited thereto. The color data 111 and the disposition data 112 can also be used as design data for designing the disposition of the colors when the display medium 1 is formed by a combination of members having predetermined colors in size or the like that cannot be formed by the inkjet printer.
