  However, in the virtual image display decorative body as disclosed in Patent Document 1, the gradation of the image of the pixel unit in the enlarged virtual image is determined by the gradation of the pixel dots forming the image of the pixel unit. For this reason, the gradation of the image in the virtual image is only two gradations of presence or absence of the image, and there is a problem that the degree of freedom of expression is poor.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  [Application Example 1] A method of manufacturing a virtual image display decorative body according to this application example includes a unit assembly in which pixel units formed by arranging pixel dots in a predetermined positional relationship are regularly two-dimensionally arranged, A lens assembly in which each lens body of the plurality of lens bodies is disposed at a position associated with the position of the pixel unit, wherein the pixel dot is a predetermined number of pixels. A unit aggregate forming step of forming the unit aggregate by forming an image portion of the pixel unit by disposing the pixel unit, and in the unit aggregate forming step, the color tone of the pixel dot is the pixel The unit aggregate including at least one background color pixel unit which is a color tone of a background portion of the unit is formed.

  According to the method of manufacturing the virtual image display decorative body according to this application example, in the unit assembly forming step, a unit assembly including at least one background color pixel unit in which the color tone of the pixel dot is the color tone of the background portion of the pixel unit Form. The background color pixel unit in which the color tone of the pixel dot is the color tone of the background portion of the pixel unit is, for example, a pixel unit in which no pixel dot is arranged. The virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the pixel unit formed by the lens body. The image part in the virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the image part of the pixel unit formed by the lens body. In the background color pixel unit, since the color tone of the pixel dot is the color tone of the background portion of the pixel unit, the virtual image of the image portion of the background color pixel unit has the color tone of the background portion. Due to the presence of the background color pixel unit, a virtual image having the color tone of the background portion exists in the image portion of the virtual image appearing on the virtual image appearing decorative body. This part can be identified individually by observing the virtual image appearing on the virtual image appearing decorative body by magnifying it to such an extent that the lens body can be visually recognized. And looks together. As a result, the entire image portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose color tone is shifted from the color tone of the image portion toward the color tone of the background portion. Similarly, the entire image portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose gradation is shifted from the gradation of the image portion to the gradation side of the background portion. Since the gradation shift amount varies depending on the number of background color pixel units, the gradation of the image portion can be adjusted by adjusting the number of background color pixel units.

  Application Example 2 In the method for manufacturing a virtual image display decorative body according to the application example, it is preferable that the background color pixel unit is arranged at a random position in the unit assembly in the unit assembly forming step.

  According to the method of manufacturing the virtual image display decorative body, the background color pixel units are arranged at random positions in the unit aggregate. The virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the pixel unit formed by the lens body. A portion of one background color pixel unit is visually recognized as a virtual image through one lens body. In the virtual image appearing on the virtual image appearing decorative body, the area occupied by one lens body is very small. In the virtual image appearing on the virtual image appearing decorative body, it is practically impossible for one background color pixel unit to be visually recognized through one lens body. Therefore, in a state where the background color pixel unit exists alone, it is difficult to visually recognize even through the lens body. However, when a large number of background color pixel units are located close to each other, the virtual image of the background color pixel dots formed through the lens body is clustered and visible in the virtual image that appears on the virtual image display decorative body. It becomes easy to be done. When the background color pixel dots are viewed as a virtual image, the image appears to be missing. By arranging the background color pixel units at random positions in the unit assembly, it is possible to prevent the virtual image of the background color pixel units from being easily seen due to the background color pixel units being placed close to each other. can do.

  [Application Example 3] In the method for manufacturing a virtual image display decorative body according to the application example described above, the method further includes a background forming step of arranging a background color material on the background part of the pixel unit to form the background part, In the background forming step, it is preferable to form at least one substrate surface background unit in which the background portion is the surface of the substrate forming the pixel unit.

  According to this method for manufacturing a virtual image appearing decorative body, there is a background forming step, and in the background forming step, a base material surface background unit is formed in which the background portion is the surface of the base material forming the pixel unit. The substrate surface background unit whose background portion is the surface of the substrate is, for example, a unit aggregate in which no background color material is arranged. The virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the pixel unit formed by the lens body. The background portion in the virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the background portion of the pixel unit formed by the lens body. In the base material surface background unit, since the color tone of the background portion is the color tone of the base material surface, the virtual image of the background portion of the base material surface background unit has the color tone of the base material surface. Due to the presence of the base material surface background unit, a virtual image having the color tone of the base material surface exists in the background portion of the virtual image that appears on the virtual image display decorative body. This part can be identified individually by observing the virtual image appearing on the virtual image display decorative body enlarged to such an extent that the lens body can be visually recognized. And looks together. As a result, the entire background portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose color tone is shifted from the color tone of the image portion to the color tone side of the background portion. Similarly, the entire background portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose gradation is shifted from the gradation of the background portion to the gradation side of the base material surface. Since the gradation shift amount differs depending on the number of base material surface background units, the gray level of the background portion can be adjusted by adjusting the number of base material surface background units.

  Application Example 4 In the method for manufacturing a virtual image display decorative body according to the application example, it is preferable that the base surface background unit is arranged at a random position in the unit assembly in the background forming step.

  According to this method for manufacturing a virtual image display decorative body, in the background forming step, the base material surface background unit is arranged at random positions in the unit assembly. The background portion of the virtual image that appears on the virtual image display decorative body is a collection of virtual images of a part of the background portion of the pixel unit formed by the lens body. One base material surface background unit is visually recognized as a virtual image through one lens body. In the virtual image appearing on the virtual image appearing decorative body, the area occupied by one lens body is very small. In the virtual image appearing on the virtual image appearing decorative body, it is practically not possible to visually recognize one base material background unit individually through one lens body. Therefore, in the state where the substrate surface background unit exists alone, it is difficult to visually recognize even through the lens body. However, when a large number of base material surface background units are located close to each other, the virtual image of the base material surface formed through the lens body is present in the virtual image that appears on the virtual image display decorative body and is visually recognized. It becomes easy. When the base material surface is visually recognized as a virtual image, the base material surface dots appear to exist in the background color. By arranging the substrate surface background unit at random positions in the unit assembly, the virtual image of the substrate surface background unit can be easily seen due to the proximity of the substrate surface background unit. Can be suppressed.

  Application Example 5 In the method for manufacturing a virtual image display decorative body according to the application example, at least one arrangement position of the background color pixel unit or the base material surface background unit in the unit aggregate is randomly dithered. It is preferable to determine by pattern.

  According to this method for manufacturing a virtual image display decorative body, the arrangement positions of the background color pixel unit and the base surface background unit in the unit aggregate are determined by the random dither pattern. This is a pattern in which the coordinate positions of points are randomly arranged using a dither method in a random dither pattern. When observing the virtual image that appears on the virtual image display decorative body by changing the arrangement position of the background color pixel unit in the unit assembly so that it does not overlap with the coordinate position of the dot in the random dither pattern The gradation fluctuation of the image portion can be suppressed. By locating the base material surface background unit in the unit assembly so that it does not overlap with the coordinate position of the dots in the random dither pattern, the virtual image appearing on the virtual image display decorative body was observed from different viewpoints. In this case, it is possible to suppress the gradation fluctuation of the background portion.

  Application Example 6 A virtual image display decorative body according to this application example includes a unit assembly in which pixel units formed by arranging pixel dots in a predetermined positional relationship are regularly arranged two-dimensionally, and a plurality of lenses. A lens assembly in which each lens body of the body is disposed at a position associated with the position of the pixel unit, and the unit assembly has a color tone of the pixel dot in a color tone of a background portion of the pixel unit. And at least one background color pixel unit.

  According to the virtual image appearing decorative body according to this application example, the unit aggregate includes at least one background color pixel unit in which the color tone of the pixel dot is the color tone of the background portion of the pixel unit. The background color pixel unit in which the color tone of the pixel dot is the color tone of the background portion of the pixel unit is, for example, a pixel unit in which no pixel dot is arranged. The virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the pixel unit formed by the lens body. The image part in the virtual image appearing on the virtual image appearing decorative body is a collection of virtual images of a part of the image part of the pixel unit formed by the lens body. In the background color pixel unit, since the color tone of the pixel dot is the color tone of the background portion of the pixel unit, the virtual image of the image portion of the background color pixel unit has the color tone of the background portion. Due to the presence of the background color pixel unit, a virtual image having the color tone of the background portion exists in the image portion of the virtual image appearing on the virtual image appearing decorative body. This part can be identified individually by observing the virtual image appearing on the virtual image appearing decorative body by magnifying it to such an extent that the lens body can be visually recognized. And looks together. As a result, the entire image portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose color tone is shifted from the color tone of the image portion toward the color tone of the background portion. Similarly, the entire image portion of the virtual image appearing on the virtual image appearing decorative body appears to be a virtual image whose gradation is shifted from the gradation of the image portion to the gradation side of the background portion. Since the gradation shift amount varies depending on the number of background color pixel units, the gradation of the image portion can be adjusted by adjusting the number of background color pixel units.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a method for manufacturing a virtual image displaying decorative body and a virtual image displaying decorative body according to the present invention will be described with reference to the drawings. In the present embodiment, the step of forming the image display unit by drawing the pixel unit constituting the unit aggregate included in the image display unit included in the virtual image display decorative body using the ink jet type droplet discharge device. An example will be described. The droplet discharge device relatively moves the droplet discharge head and the drawing medium, and discharges a droplet of the functional liquid from the discharge nozzle of the droplet discharge head to land on a predetermined position on the drawing medium. This is a device for forming a predetermined image or the like. In the drawings referred to in the following description, the vertical and horizontal scales of members or portions may be shown differently from actual ones for convenience of illustration.

<Droplet ejection device>
First, the droplet discharge device 1 will be described with reference to FIG. FIG. 1 is an external perspective view showing a schematic configuration of a droplet discharge device. FIG. 1A is an external perspective view showing a schematic configuration of the entire droplet discharge device, and FIG. 1B is an external perspective view showing a schematic configuration of a droplet discharge head included in the droplet discharge device. .

  As shown in FIG. 1, the droplet discharge device 1 includes a head mechanism unit 2, a work mechanism unit 3, a functional liquid supply unit 4, a maintenance device unit 5, and a discharge device control unit 7. . The head mechanism unit 2 includes a droplet discharge head 20 that discharges functional liquid as droplets. The head mechanism unit 2 also has an ultraviolet irradiation unit (not shown). The work mechanism unit 3 includes a work mounting table 33 on which a work W that is a discharge target (drawing target) of a droplet discharged from the droplet discharge head 20 is mounted. The functional liquid supply unit 4 supplies the functional liquid to the droplet discharge head 20. The maintenance device unit 5 performs maintenance of the droplet discharge head 20. The discharge device control unit 7 comprehensively controls these mechanism units. The droplet discharge device 1 further includes a plurality of support legs 8 installed on the floor and a surface plate 9 installed on the upper side of the support legs 8.

  On the upper surface of the surface plate 9, the work mechanism unit 3 is disposed. The work mechanism unit 3 extends in the longitudinal direction (X-axis direction) of the surface plate 9. Above the work mechanism unit 3, the head mechanism unit 2 supported by two support columns fixed to the surface plate 9 is disposed. The head mechanism unit 2 extends in a direction (Y-axis direction) substantially orthogonal to the work mechanism unit 3. A functional liquid tank of the functional liquid supply unit 4 having a supply pipe communicating with the liquid droplet ejection head 20 of the head mechanism unit 2 is disposed beside the surface plate 9. In the vicinity of one support column of the head mechanism unit 2, a maintenance device unit 5 is arranged along with the work mechanism unit 3 so as to extend in the X-axis direction. Further, a discharge device control unit 7 is accommodated below the surface plate 9.

  The head mechanism unit 2 includes a head unit 21 having a droplet discharge head 20 and a head carriage 22 that supports the head unit 21. By moving the head carriage 22 in the Y-axis direction, the droplet discharge head 20 is freely moved in the Y-axis direction. Moreover, it holds at the moved position. The workpiece mechanism unit 3 moves the workpiece mounting table 33 in the X-axis direction to freely move the workpiece W mounted on the workpiece mounting table 33 in the X-axis direction. Moreover, it holds at the moved position.

The droplet discharge head 20 is moved to the discharge position in the Y-axis direction and stopped, and the functional liquid is discharged as droplets in synchronization with the movement of the work W below in the X-axis direction. The X-axis direction, which is the relative movement direction (scanning direction) between the droplet discharge head 20 and the workpiece W, accompanied by the discharge of the functional liquid from the droplet discharge head 20, is referred to as a discharge scanning direction.
By relatively controlling the workpiece W moved in the X-axis direction and the droplet discharge head 20 moved in the Y-axis direction, droplets are landed at an arbitrary position on the workpiece W, thereby making a desired drawing. Etc. can be performed.

  As shown in FIG. 1B, the droplet discharge head 20 includes a nozzle substrate 25. In the nozzle substrate 25, two rows of nozzle rows 24A in which a large number of discharge nozzles 24 are arranged in a substantially straight line are formed. The functional liquid is ejected as droplets from the ejection nozzle 24 and landed on the workpiece W or the like located at the opposite position, thereby arranging the functional liquid at the position. The nozzle row 24A extends in the Y-axis direction shown in FIG. 1A in a state where the droplet discharge head 20 is mounted on the droplet discharge device 1. In the nozzle row 24A, the discharge nozzles 24 are arranged at equal nozzle pitches, and the position of the discharge nozzle 24 is shifted by a half nozzle pitch in the Y-axis direction between the two nozzle rows 24A. Therefore, as the liquid droplet ejection head 20, functional liquid droplets can be arranged at half nozzle pitch intervals in the Y-axis direction.

In order to extend the drawing range in the Y-axis direction, the droplet discharge head 20 may be connected in the Y-axis direction, or the droplet discharge head 20 may be moved in the Y-axis direction to The movement of the workpiece W in the X-axis direction and the discharge from the droplet discharge head 20 may be performed for each position in the direction.
In order to reduce the arrangement pitch of the droplets in the Y-axis direction, a plurality of droplet ejection heads 20 may be arranged in the X-axis direction by shifting the positions of the ejection nozzles 24 in the Y-axis direction. A droplet discharge head having a nozzle row of may be used. Of course, a droplet discharge head having a small nozzle pitch can be used as long as it can be manufactured.

<Landing position>
Next, the relationship between the discharge nozzles 24 of the droplet discharge head 20 and the landing positions of the droplets discharged from the respective discharge nozzles 24 will be described with reference to FIG. FIG. 2 is an explanatory diagram showing the relationship between the discharge nozzles and the landing positions of the liquid droplets discharged from the respective discharge nozzles. FIG. 2A is an explanatory view showing the arrangement position of the discharge nozzles, and FIG. 2B is an explanatory view showing a state where droplets are landed linearly in the extending direction of the nozzle rows, FIG. 2C is an explanatory diagram illustrating a state in which droplets are landed linearly in the ejection scanning direction, and FIG. 2D is an explanatory diagram illustrating a state in which droplets are landed in a planar shape. is there. The X-axis direction and the Y-axis direction shown in FIG. 2 coincide with the X-axis direction or the Y-axis direction shown in FIG. 1 when the head unit 21 is attached to the droplet discharge device 1. The X-axis direction is the discharge scanning direction, and the functional liquid droplets are discharged at an arbitrary position while the discharge nozzle 24 (droplet discharge head 20) is relatively moved in the direction of arrow a shown in FIG. Thus, the droplet can be landed at an arbitrary position in the X-axis direction.

  As shown in FIG. 2A, the discharge nozzles 24 constituting the nozzle row 24A are arranged at the center distance of the nozzle pitch P in the Y-axis direction. As described above, the positions of the discharge nozzles 24 constituting the two nozzle rows 24A are shifted from each other by ½ of the nozzle pitch P in the Y-axis direction.

  As shown in FIG. 2 (b), the landing point 91 indicating the landing position and the landing circle 91A indicating the wet and spreading state of the landed liquid droplets indicate the state of one landed liquid droplet. By discharging droplets from all the discharge nozzles 24 of the two nozzle rows 24A on the virtual line L indicated by the two-dot chain line in FIG. A pattern is formed in which the landing circles 91A are linearly connected at the center-to-center spacing of / 2.

  As shown in FIG. 2C, by continuously ejecting droplets from one ejection nozzle 24, a pattern in which landing circles 91A are linearly connected in the X-axis direction is formed. The minimum value of the center-to-center distance between the landing points 91 in the X-axis direction is denoted as the minimum landing distance d. The minimum landing distance d is a product of the relative movement speed in the X-axis direction and the minimum discharge interval (time) of the discharge nozzle 24.

  As shown in FIG. 2D, by ejecting liquid droplets at the timing of landing on virtual lines L1, L2, and L3 indicated by two-dot chain lines, the center-to-center spacing of 1/2 of the nozzle pitch P is obtained. Thus, a landing surface is formed in which the straight lines connecting the landing circles 91A are arranged in parallel in the X-axis direction. Each landing point 91 in the case where the distance between the virtual lines L1, L2, and L3 shown in FIG. 2D is the minimum landing distance d is a position at which the droplet of the functional liquid can be disposed by the droplet discharge device 1. is there.

  At the time of drawing an image, a position where a droplet is arranged is determined for each landing point 91 shown in FIG. For example, by forming a pixel arrangement diagram that designates the arrangement position and the discharge nozzle 24 that ejects droplets at the arrangement position, and landing the functional liquid according to the pixel arrangement drawing, an image defined by the image information is obtained. draw. In the example shown in FIG. 2 (d), there is a gap between the landing circles 91A. However, the discharge weight per one droplet to be discharged is appropriate for the nozzle pitch P and the minimum landing distance d. It is possible to arrange the functional liquid without gaps. Of course, it is also possible to arrange one droplet independently without overlapping other droplets.

FIG. 4D is an enlarged plan view of the pixel aggregate, and FIG. 4E is a lens array and a pixel aggregate of the virtual image appearing ornament. FIG. 4F is an enlarged plan view of the lens array and the pixel aggregate.

  As shown in FIG. 3A, the virtual image display decorative body 51 includes a base material 53, a microlens array 61, and a pixel aggregate 71. The base material 53 is a film-like member formed of a transparent material. Examples of the material of the base material 53 include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC) polyvinyl chloride (PVC), polyvinyl alcohol (PVA), and the like. A liquid repellent layer 55 is formed on one surface of the substrate 53. On the liquid repellent layer 55, a micro lens 62 constituting the micro lens array 61 is formed. A pixel unit 72 constituting the pixel aggregate 71 is formed on the surface of the substrate 53 opposite to the surface on which the liquid repellent layer 55 is formed.

  When viewed from the direction of the arrow s shown in FIG. 3A, the pixel virtual image 73 can be visually recognized as shown in FIG. In FIG. 3B, the character A, the character B, the character C, and the character D are illustrated as the pixel virtual image 73. The pixel virtual image 73 having the shape of the character A, the character B, the character C, or the character D is referred to as a pixel virtual image 73A, a pixel virtual image 73B, a pixel virtual image 73C, or a pixel virtual image 73D. One pixel virtual image 73 appears corresponding to one pixel aggregate 71. An area where one pixel aggregate 71 is formed and one pixel virtual image 73 appears is referred to as an aggregate area 710. The aggregate area 710 in which the pixel virtual image 73A, the pixel virtual image 73B, the pixel virtual image 73C, or the pixel virtual image 73D is formed is referred to as an aggregate area 710a, an aggregate area 710b, an aggregate area 710c, or an aggregate area 710d.

  The microlens array 61 is formed by arranging microlenses 62 in a lattice shape at equal pitch intervals. A set of microlenses 62 formed at a position corresponding to one aggregate area 710 is referred to as a microlens array 61, and a set of microlenses 62 formed on the entire virtual image display decorative body 51 is referred to as a microlens. This is expressed as an array 610. A microlens array 610 is formed in a region indicated by a two-dot chain line in FIG. As shown in FIG. 4B, in the microlens array 61, the microlenses 62 are arranged vertically and horizontally at a pitch P1. In the microlens array 61, for example, 2025 microlenses 62 are formed in 45 rows × 45 columns. The pitch P1 is, for example, 180 μm.

A region surrounded by a two-dot chain line shown in FIG. 4C shows a single aggregate region 710. One pixel aggregate 71 is formed in one aggregate area 710. The pixel aggregate 71 formed in the aggregate area 710a, the aggregate area 710b, the aggregate area 710c, or the aggregate area 710d is replaced with the pixel aggregate 71a, the pixel aggregate 71b, the pixel aggregate 71c, or the pixel aggregate. This is expressed as 71d. As shown in FIG. 4D, in the pixel aggregate 71, pixel units 72 are arranged vertically and horizontally at a pitch P2. The pitch P2 and the pitch P1 are the pitch P1 × (number of rows or columns of the microlenses 62 in the microlens array 61−1) = pitch P2 × (number of rows or columns of the pixel units 72 in the pixel aggregate 71). It is set to a value that satisfies the relationship.

Alternatively, the pixel units 72d are arranged at a pitch P2.
In the pixel assembly 71, for example, 2025 pixel units 72 are formed in 45 rows × 45 columns. The pitch P2 is, for example, 176 μm.

  As shown in FIG. 4 (e), in the virtual image appearing decorative body 51, the microlens array 61 and the pixel aggregate 71 are formed so as to overlap in a direction parallel to the surface of the base material 53. A set of the microlens array 61 and the pixel aggregate 71 that causes the pixel virtual image 73 to appear is referred to as a virtual image unit 76. The virtual image unit 76 that displays the pixel virtual image 73A, the pixel virtual image 73B, the pixel virtual image 73C, or the pixel virtual image 73D is referred to as a virtual image unit 76a, a virtual image unit 76b, a virtual image unit 76c, and a virtual image unit 76d.

As shown in FIG. 4F, in the virtual image unit 76 (virtual image unit 76a), the centers of the microlens 620 of the microlens array 61 and the pixel unit 720 of the pixel aggregate 71 coincide with each other. The micro lens 620 is the micro lens 62 at the center of the micro lens array 61, and the pixel unit 720 is the pixel unit 72 at the center of the pixel assembly 71. The center positions of the microlens 62 adjacent to the microlens 620 and the pixel unit 72 adjacent to the pixel unit 720 are shifted by an amount corresponding to the difference between the pitch P1 and the pitch P2. When P1 is 180 μm and the pitch P2 is 176 μm, the deviation is 4 μm.
At the end of the virtual image unit 76, the center position of the pixel unit 72 constituting the row or column at the end of the row or column of the pixel unit 72 included in the pixel assembly 71 is the row or column of the microlens 62 included in the microlens array 61. It is located at the midpoint between the center position of the microlens 62 constituting the end row or column in the column and the center position of the microlens 62 constituting the second row or column from the end.
The pixel aggregate 71 corresponds to a unit aggregate. The micro lens 62 corresponds to a lens body. The microlens array 61 corresponds to a lens assembly.

  In the virtual image displaying decorative body 51 configured as described above, a virtual image of a part of the pixel unit 72 is formed by the micro lens 62 corresponding to the pixel unit 72. In the virtual image unit 76, the portion of the pixel unit 72 formed as a virtual image is different for each microlens 62 corresponding to the pixel unit 72. Therefore, in the virtual image unit 76, a pixel virtual image 73 in which the pixel unit 72 is enlarged by the microlens 62 is formed so as to be visible.

<Pixel assembly and pixel unit>
Next, the configuration of the pixel aggregate 71 included in the virtual image display decorative body 51 and the configuration of the pixel unit 72 included in the pixel aggregate 71 will be described with reference to FIGS. 5 and 6.

  FIG. 5A is the same diagram as FIG. As shown in FIG. 5A, the virtual image displaying decorative body 51 includes four aggregate regions 710. As described with reference to FIG. 4C, one pixel aggregate 71 is formed in one aggregate area 710. In the aggregate area 710a, the aggregate area 710b, the aggregate area 710c, and the aggregate area 710d, a pixel aggregate 71a, a pixel aggregate 71b, a pixel aggregate 71c, or a pixel aggregate 71d is formed.

  As shown in FIG. 5B, the pixel aggregate 71a has 2025 pixel units 72a with 45 rows × 45 columns. The arrangement pitch of the pixel units 72a is, for example, 176 μm for both the row pitch and the column pitch. The same applies to pixel assemblies 71 other than the pixel assembly 71a, such as the pixel assembly 71b. In the pixel assembly 71b, the pixel assembly 71c, and the pixel assembly 71d, 2025 pixel units 72b, pixel units 72c, or pixel units 72d are formed in 45 rows × 45 columns.

  As shown in FIG. 6A, the pixel unit 72a is formed by arranging 16 pixel dots 75 in a predetermined positional relationship. The pixel unit 72 forms one pixel unit 72 in the pixel unit region 721 in which the pixel dots 75 can be arranged in 16 rows × 16 columns. In FIG. 6E, the pixel unit region 721 is shown divided into pixel dot sections 751 of 16 rows × 16 columns. A pixel dot section 751 corresponding to the pixel dot 75 in the pixel dot section 751 is referred to as a pixel section 751a. A pixel dot section 751 that corresponds to the background portion of the pixel unit 72 and that remains on the surface of the base 53 is referred to as a base color section 751b. As shown in FIG. 6E, the pixel unit 72a is formed by arranging 16 pixel sections 751a at predetermined relative positions. In the pixel unit area 721a where the pixel unit 72a is formed, there are 16 × 16−16 = 240 base material color sections 751b.

When the pixel aggregate 71 is formed using the above-described droplet discharge device 1, the pixel dot 75 corresponds to the landing point 91 described with reference to FIG. 2, and the pixel dot section 751 corresponds to the landing circle 91A. . With respect to the positions of the respective landing points 91 shown in FIG. 2D, the landing points 91 and the droplets that land the droplets correspond to the positions of the pixel dots 75 of the pixel unit 72 in the pixel aggregate 71 to be drawn. By defining the landing points 91 that are not landed, a pixel layout that defines the positions where the liquid droplets are landed is formed. A pixel aggregate 71 is drawn by landing a droplet at a position corresponding to the landing point 91 in the formed pixel arrangement diagram.

  As described with reference to FIG. 2, the functional liquid can be arranged without a gap by appropriately determining the discharge weight per droplet of the droplets to be discharged. As the landed droplets spread out, the pixel unit 72 has a shape formed by connecting pixel dots 75 or pixel dot sections 751 together. The pixel aggregate 71, which is a set of the pixel units 72, is visually recognized as a virtual image through the microlens array 61, so that it is visually recognized as a pixel virtual image 73 as illustrated in FIG.

<Adjusted Pixel Assembly Example 1>
Next, an adjustment pixel aggregate in which the gradation of the image and the gradation of the background in the virtual image to be displayed is adjusted will be described with reference to FIG. The adjusted pixel aggregate is formed by adjusting the number of pixel units 72 in the pixel aggregate 71. FIG. 7 is an explanatory diagram showing the arrangement of pixel units in the adjustment pixel assembly. FIG. 7A is an explanatory diagram showing the arrangement of pixel units in a pixel assembly in which gradation adjustment is not performed, and FIG. 7B is a diagram of the pixel assembly shown in FIG.

The pixel unit region 725 includes a base color section 751b. The pixel unit region 725 is formed by arranging base color sections 751b in 16 rows × 16 columns. That is, the pixel unit region 725 is a region that does not include the pixel section 751a and in which the pixel dot 75 is not disposed. In other words, the base color unit 745 is obtained by deleting the pixel dot 75 from the pixel unit 72. The base color unit 745 in the pixel aggregate 715 corresponds to the background color pixel unit.

In the step of forming the pixel aggregate 715, a droplet for forming the pixel dot 75 is disposed at the position of the pixel section 751a in the pixel unit region 721. Since there is no pixel section 751a in the pixel unit region 725, no droplets for forming the pixel dots 75 are disposed, and the surface of the base material 53 is maintained as it is in the pixel unit region 725.
As shown in FIG. 7B, the pixel aggregate 715 includes approximately the same number of pixel units 72 and a base color unit 745. Therefore, the pixel aggregate 715 includes half as many pixel units 72 as the pixel units 72 included in the pixel aggregate 71. The gradation of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 715 is the image portion (character A in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 71. ) Gradation of approximately 50%.

A pixel aggregate 714 partially shown in FIG. 7C includes a pixel unit 74. The pixel aggregate 714 is formed in the aggregate area 704. The aggregate area 704 includes a pixel unit area 726. In the aggregate region 704, the pixel unit regions 726 are arranged in 45 rows × 45 columns.
The pixel unit 74 is formed in the pixel unit region 726. Similar to the pixel unit region 721, the pixel unit region 726 is formed by arranging pixel dot sections 751 in 16 rows × 16 columns.

The pixel unit region 726 includes a pixel section 751a and a background color section 751c. As described above, the pixel section 751a is the pixel dot section 751 in which the pixel dots 75 are arranged. In the pixel unit area 726, the pixel section 751 a is arranged in the same manner as the pixel section 751 a in the pixel unit area 721. An image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 714 is a virtual image aggregate of a part of the pixel section 751 a formed through the microlens 62. The color tone of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 714 is the color tone of the substantially pixel section 751a, and the gradation is the gradation of the approximately pixel section 751a.
The background color section 751c is a pixel dot section 751 colored to the background color. In the pixel unit region 726, a pixel dot section 751 other than the pixel section 751a is a background color section 751c. The background portion of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 714 is a collection of virtual images of a part of the background color section 751c formed through the microlens 62. . The color tone of the background portion of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 714 is substantially the color tone of the background color section 751c, and the gradation is the substantially background color section 751c. Gradation.

  In the step of forming the pixel aggregate 714, first, a background color material is disposed at the position of the background color section 751c. For example, droplets for forming a background color are arranged on the entire surface of the adjusted aggregate region 706 so that the entire surface of the aggregate region 704 is the background color. Next, a droplet for forming the pixel dot 75 is disposed at the position of the pixel section 751 a in the pixel unit region 726.

A pixel aggregate 716 partially shown in FIG. 7D includes a pixel unit 74 and a background color unit 747. The pixel aggregate 716 is formed in the adjustment aggregate area 706. The adjusted assembly area 706 includes a pixel unit area 726 and a pixel unit area 727.
The background color unit 747 is formed in the pixel unit region 727. The pixel unit area 727 includes a background color section 751c. The pixel unit region 727 is formed by arranging background color sections 751c in 16 rows × 16 columns. That is, the pixel unit area 727 is an area that does not include the pixel section 751a and in which the pixel dot 75 is not disposed. In other words, the background color unit 747 is obtained by deleting the pixel dot 75 from the pixel unit 74. The background color unit 747 in the pixel aggregate 716 corresponds to the background color pixel unit.

  In the step of forming the pixel aggregate 716, first, a background color material is disposed at the position of the background color section 751c. For example, droplets for forming a background color are arranged on the entire surface of the adjusted aggregate region 706 so that the entire surface of the adjusted aggregate region 706 has a background color. Next, a droplet for forming the pixel dot 75 is disposed at the position of the pixel section 751 a in the pixel unit region 726. Since the pixel section 751a does not exist in the pixel unit region 727, no droplet for forming the pixel dot 75 is disposed, and the background color surface is maintained as it is in the pixel unit region 727.

As shown in FIG. 7D, the pixel aggregate 716 includes approximately the same number of pixel units 74 and a background color unit 747. Therefore, the pixel aggregate 716 includes approximately half as many pixel units 74 as the pixel units 74 included in the pixel aggregate 714. The gradation of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 716 is the gradation of the image portion (character A in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714. ) Gradation of approximately 50%.
The background portion of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 716 is a virtual image of a portion of the background portion in the pixel unit 74 formed through the microlens 62, and This is a collection of virtual images of a part of the background color unit 747. The background portion in the pixel unit 74 is a background color section 751c. The entire background color unit 747 is a background color section 751c. Therefore, the background portion of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 716 is a collection of virtual images of a part of the background color section 751 c formed through the microlens 62.

Gradation.

A pixel assembly 717 partially shown in FIG. 7E includes a pixel unit 74 and a base color unit 745. The pixel aggregate 717 is formed in the adjustment aggregate area 707. The adjusted aggregate area 707 includes a pixel unit area 726 and a pixel unit area 725.
The pixel unit 74 is formed in the pixel unit region 726. As described above, the pixel unit region 726 is formed by arranging the pixel dot sections 751 in 16 rows × 16 columns. The pixel unit region 726 includes a pixel section 751a and a background color section 751c.
The base color unit 745 is formed in the pixel unit region 725. As described above, the pixel unit region 725 includes the base color section 751b, and the base color section 751b is formed by being arranged in 16 rows × 16 columns. The pixel unit area 725 is an area in which the pixel section 751 is not provided and the pixel dot 75 is not disposed. The base color unit 745 in the pixel aggregate 717 corresponds to the base surface background unit.

  In the step of forming the pixel aggregate 717, first, a background color material is disposed at the position of the background color section 751c. For example, a droplet for forming a background color is arranged on the entire surface of the adjustment assembly region 707 in the position of the pixel unit region 726, and the portion of the pixel unit region 726 in the adjustment assembly region 707 is set to the background color. . Next, a droplet for forming the pixel dot 75 is disposed at the position of the pixel section 751 a in the pixel unit region 726. Since the pixel section 751a does not exist in the pixel unit region 725, a droplet for forming the pixel dot 75 is not disposed. In the pixel unit region 725, no liquid droplet for forming the background color is arranged, and no liquid droplet for forming the pixel dot 75 is arranged, so that the surface of the base material 53 is maintained as it is.

  As shown in FIG. 7E, the pixel aggregate 717 includes approximately the same number of pixel units 74 and a base color unit 745. Therefore, the pixel aggregate 717 includes approximately half the number of pixel units 74 of the pixel units 74 included in the pixel aggregate 714. The image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 717 is an aggregate of virtual images of a part of the pixel dots 75 in the pixel unit 74 formed through the microlens 62. is there. The gradation of the image portion (character A) in the virtual pixel image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 717 is the gradation of the image portion (character A in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714. ) Gradation of approximately 50%.

  The background portion of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 717 is a virtual image of a portion of the background portion in the pixel unit 74 formed through the microlens 62, and This is a collection of virtual images of a part of the base color unit 745. The background portion in the pixel unit region 726 is a background color section 751c. The entire surface of the base color unit 745 is a base color section 751b. The pixel aggregate 717 includes approximately the same number of pixel units 74 and base color units 745, and the pixel aggregate 717 includes approximately half as many pixel units as the pixel units 74 included in the pixel aggregate 714. 74 is provided. Therefore, the gradation of the background portion of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 717 is in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714. This is approximately 50% of the gradation of the background portion of the image portion (character A).

A pixel aggregate 718 partially shown in FIG. 7F includes a pixel unit 74, a base color unit 745, and a background color unit 747. The pixel aggregate 718 is formed in the adjustment aggregate area 708. The adjusted aggregate area 708 includes a pixel unit area 726, a pixel unit area 725, and a pixel unit area 727.
The pixel unit 74 is formed in the pixel unit region 726. The base color unit 745 is formed in the pixel unit region 725. The background color unit 747 is formed in the pixel unit region 727. The pixel unit region 726 includes a pixel section 751a and a background color section 751c. The pixel unit region 725 includes a base color section 751b. The pixel unit area 727 includes a background color section 751c.

In the step of forming the pixel aggregate 718, first, a background color material is arranged at the position of the background color section 751c. For example, in the adjustment aggregate region 708, droplets for forming a background color are arranged on the entire surface of the pixel unit region 726 and the entire position of the pixel unit region 727, so that the pixels in the adjustment aggregate region 708 are arranged. The unit area 726 and the pixel unit area 727 are set to the background color. Next, a droplet for forming the pixel dot 75 is disposed at the position of the pixel section 751 a in the pixel unit region 726.
In the pixel unit region 725 and the pixel unit region 727, since the pixel section 751a does not exist, a droplet for forming the pixel dot 75 is not arranged. In the pixel unit region 725, no liquid droplet for forming the background color is arranged, and no liquid droplet for forming the pixel dot 75 is arranged, so that the surface of the base material 53 is maintained as it is. In the pixel unit region 727, a droplet for forming the background color is arranged, and a droplet for forming the pixel dot 75 is not arranged, so that the background color surface is maintained as it is.
The base color unit 745 in the pixel aggregate 718 corresponds to the base surface background unit. The base color unit 745 and the background color unit 747 in the pixel aggregate 718 correspond to the background color pixel unit.

  As shown in FIG. 7F, the pixel units 74 in the pixel aggregate 718 are arranged in the same manner as the pixel units 74 in the pixel aggregate 716 and the pixel aggregate 717. Therefore, the gradation of the image portion (character A) in the virtual pixel image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 718 is the pixel virtual image that appears in the virtual image unit 76 that includes the pixel aggregate 716 or the pixel aggregate 717. 73, which is substantially the same as the gradation of the image portion (character A). In addition, the gradation of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 718 is the image portion in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714 ( It is approximately 50% of the gradation of the letter A).

The background portion of the image portion (letter A) in the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 718 is a virtual image or base of a portion of the background portion in the pixel unit 74 formed through the microlens 62. It is a collection of a virtual image of a part of the material color unit 745 and a virtual image of a part of the background color unit 747. The background portion in the pixel unit region 726 is a background color section 751c. The entire background color unit 747 is a background color section 751c. The entire surface of the base color unit 745 is a base color section 751b.
The pixel aggregate 718 includes approximately the same number of background color units 747 and base color units 745, and is a number approximately equal to the total number of the background color units 747 and the base color units 745. The pixel unit 74 is provided. In the background color unit 747, the base color unit 745, and the pixel unit 74 included in the pixel aggregate 718, the background color unit 747 and the pixel unit 74 occupy 75%. Therefore, the gradation of the background portion of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 718 is in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714. This is approximately 75% of the gradation of the background portion of the image portion (character A).
The positions of the base color units 745 in the pixel aggregate 718 shown in FIG. 7F are regularly arranged because the illustrated range is narrow, but are preferably arranged at random positions. By disposing the base color unit 745 at random positions, the virtual image of the base color unit 745 is separated and visually recognized in the background portion of the image portion in the pixel virtual image 73 as compared to the regular placement. The possibility of being reduced can be reduced. Further, it is possible to suppress the occurrence of gradation spots in the background portion of the image portion in the pixel virtual image 73.

<Adjusted Pixel Assembly Example 2>
Next, an adjustment pixel assembly that is partially different from the above-described pixel assembly 715 and the like will be described with reference to FIG. FIG. 8 is an explanatory diagram of a pixel aggregate in which the position of the pixel unit is set using a random dither mask. FIG. 8A is an explanatory diagram of a random dither mask, and FIG. 8B is an explanatory diagram showing an arrangement of pixel units in the adjustment pixel aggregate.

  As described above, by reducing the number of pixel units 72 in the aggregate region 710, the gradation of the image portion (character A or the like) in the pixel virtual image 73 appearing in the virtual image unit 76 is adjusted. For example, in the pixel aggregate 715, the number of the pixel units 72 is half that of the pixel aggregate 71, whereby the image portion (character A) of the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 715 is displayed. The gradation is set to about 50% of the gradation of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 71.

The random dither mask 81 shown in FIG. 8A is a random dither mask with 5% gradation. As shown in FIG. 8A, the random dither mask 81 includes a black spot portion 82 and a white spot portion 83. The total of the number of black spot portions 82 and the number of white spot portions 83 is, for example, 2025 corresponding to 45 × 45 = 2005 pixel units 72 included in the pixel aggregate 71. The random dither mask 81 has a 5% gradation, and the black dot portions 82 included in the random dither mask 81 are approximately 25% of 2025.
The position of the black dot portion 82 in the random dither mask 81 is set to a random position based on a random dither pattern formed using the dither method.

A pixel aggregate 711 partially shown in FIG. 8B includes a pixel unit 72 and a base color unit 745. The pixel aggregate 711 is formed in the adjusted aggregate area 701. The adjusted assembly area 701 includes a pixel unit area 721 and a pixel unit area 725.
The pixel unit 72 is formed in the pixel unit region 721. The pixel unit region 721 includes a pixel section 751a, and the pixel unit 72 is formed by disposing pixel dots 75 in a pixel section 751a disposed at a predetermined relative position.
The base color unit 745 is formed in the pixel unit region 725. The pixel unit region 725 includes a base color section 751b. The pixel unit area 725 does not include the pixel section 751a and is an area where the pixel dots 75 are not disposed, and the base color unit 745 is an area where the pixel dots 75 are not disposed.

  In the step of forming the pixel aggregate 711, a droplet for forming the pixel dot 75 is arranged at the position of the pixel section 751 a in the pixel unit region 721. Since there is no pixel section 751a in the pixel unit region 725, no droplets for forming the pixel dots 75 are disposed, and the surface of the base material 53 is maintained as it is in the pixel unit region 725.

In the pixel aggregate 711 partially shown in FIG. 8B, the position of the pixel unit 72 is set so as to correspond to the position of the black spot portion 82 in the random dither mask 81. That is, the position of the pixel unit area 721 in the adjusted aggregate area 701 corresponds to the position of the black spot portion 82 in the random dither mask 81. The portion of the pixel aggregate 711 shown in FIG. 8B is a portion corresponding to the partial region 81a shown in FIG.
The random dither mask 81 has 5% gradation, and the pixel aggregate 711 includes 5% of the pixel units 72 of the pixel units 72 included in the pixel aggregate 71. The gradation of the image portion (character A) in the virtual pixel image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 711 is the image portion (character A in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 71. ) Is approximately 5% of the gradation.

<Adjusted pixel assembly example 3>
Next, an adjustment pixel assembly that is partially different from the above-described pixel assembly 715 and the like will be described with reference to FIG. FIG. 9 is an explanatory diagram of a pixel aggregate in which the position of the pixel unit is set using a random dither mask. FIG. 9A is an explanatory diagram of a random dither mask, and FIG. 9B is an explanatory diagram showing an arrangement of pixel units in the adjustment pixel aggregate.

  As described above, by reducing the number of pixel units 72 in the aggregate region 710, the gradation of the image portion (character A or the like) in the pixel virtual image 73 appearing in the virtual image unit 76 is adjusted. For example, in the pixel aggregate 715, the number of the pixel units 72 is half that of the pixel aggregate 71, whereby the image portion (character A) of the pixel virtual image 73 that appears in the virtual image unit 76 including the pixel aggregate 715 is displayed. The gradation is set to about 50% of the gradation of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 including the pixel aggregate 71.

The random dither mask 89 shown in FIG. 9A is a 95% gradation random dither mask. As shown in FIG. 9A, the random dither mask 89 includes a black spot portion 82 and a white spot portion 83. The total of the number of black spot portions 82 and the number of white spot portions 83 is, for example, 2025 corresponding to 45 × 45 = 2005 pixel units 72 included in the pixel aggregate 71. The random dither mask 89 has a gradation of 95%, and the black dot portion 82 provided in the random dither mask 89 is approximately 95% of 2025.
The position of the black dot portion 82 in the random dither mask 89 is set to a random position based on a random dither pattern formed using the dither method.

A pixel aggregate 719 partially shown in FIG. 9B includes a pixel unit 72 and a base color unit 745. The pixel aggregate 719 is formed in the adjustment aggregate area 709. The adjusted assembly area 709 includes a pixel unit area 721 and a pixel unit area 725.
The pixel unit 72 is formed in the pixel unit region 721. The pixel unit region 721 includes a pixel section 751a, and the pixel unit 72 is formed by disposing pixel dots 75 in a pixel section 751a disposed at a predetermined relative position.
The base color unit 745 is formed in the pixel unit region 725. The pixel unit region 725 includes a base color section 751b. The pixel unit area 725 does not include the pixel section 751a and is an area where the pixel dots 75 are not disposed, and the base color unit 745 is an area where the pixel dots 75 are not disposed.

  In the step of forming the pixel aggregate 719, a droplet for forming the pixel dot 75 is arranged at the position of the pixel section 751a in the pixel unit region 721. Since there is no pixel section 751a in the pixel unit region 725, no droplets for forming the pixel dots 75 are disposed, and the surface of the base material 53 is maintained as it is in the pixel unit region 725.

In the pixel aggregate 719 partially shown in FIG. 9B, the position of the pixel unit 72 is set so as to correspond to the position of the black dot portion 82 in the random dither mask 89. That is, the position of the pixel unit area 721 in the adjustment aggregate area 709 corresponds to the position of the black spot portion 82 in the random dither mask 89. The portion of the pixel aggregate 719 shown in FIG. 9B is a portion corresponding to the partial region 89a shown in FIG.
The random dither mask 89 has a gradation of 95%, and the pixel aggregate 719 includes 95% of the pixel units 72 of the pixel units 72 included in the pixel aggregate 71. The gradation of the image portion (character A) in the virtual pixel image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 719 is the image portion (character A in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 71. ) Is approximately 95% of the gradation.

In this manner, by adjusting the number of pixel units 72 included in the pixel aggregate 71, the gradation of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 can be adjusted.

  (2) The pixel aggregate 717 includes approximately half as many pixel units 74 as the pixel units 74 included in the pixel aggregate 714. In the background portion of the image (character) portion in the pixel unit 74, a background color material is arranged. The gradation of the background portion of the image portion (character A) in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 717 is the image portion in the pixel virtual image 73 that appears in the virtual image unit 76 that includes the pixel aggregate 714. This is approximately 50% of the gradation of the background portion of (letter A). In this manner, in a pixel assembly such as the pixel assembly 714 having a pixel unit in which the background portion of the image is colored like the pixel unit 74, the background portion included in the pixel assembly is colored. By adjusting the number of the pixel units, the gradation of the background portion of the image portion (character A) in the pixel virtual image 73 appearing in the virtual image unit 76 can be adjusted.

  (3) The pixel aggregate 711 and the pixel aggregate 719 are arranged according to the random dither mask 81 or the random dither mask 89 formed based on the random dither pattern formed by using the dither method. The position is specified.
