  However, in the conventional image display body, the cost of a mold for producing a lenticular lens is likely to be expensive, the point that it is difficult to form a high-precision lenticular lens even if a high cost is spent, and There is a problem in that it is difficult to attach the lenticular lens to a suitable position on the parallax image.

  Accordingly, the present invention has been made in view of these points, and an object of the present invention is to provide a novel image display body capable of suitably displaying a stereoscopic image or the like without using a lenticular lens. Yes.

  In order to achieve the above-described object, an image display body of the present invention includes, as a first aspect, a medium having a smooth surface, a left eye for each image width a unit, and formed on the surface of the medium. A parallax image in which the image for the right eye and the image for the right eye are repeated, a smooth transparent layer whose thickness is set to L1 on the surface of the parallax image, and the parallax image on the surface of the transparent layer A light-shielding pattern that separates the parallax image into the left-eye image and the right-eye image so as to be seen as an image, and a distance from the light-shielding pattern to the observer on the light-shielding pattern side is L2 In this case, the inter-pattern distance X in the light shielding pattern is set to 0 <X ≦ a · L2 / (L2 + L1), and the distance from the light shielding pattern to the observer on the parallax image side When it is a L3, pattern distance X in the light-shielding pattern is set to 0 <X ≦ a · L3 / (L3-L1).

  According to the image display body of the first aspect, a suitable tolerance is set based on the thickness L1 and the observation distances L2 and 3 of the transparent medium that are the distance between the parallax image and the light shielding pattern and the image width a of the parallax image. Since the light shielding pattern having the pattern inter-pattern distance X is formed, only one of the left-eye image and the right-eye image is applied to either the front surface or the back surface of the medium with respect to one eye of the observer. It can also be displayed from the side.

  An image display body according to a second aspect of the present invention is characterized in that the image display body according to the first aspect includes a reflective layer formed on the back surface of the medium formed transparently.

  According to the image display body of the second aspect, the parallax image can be brightly displayed using the light reflected by the reflection layer, and the reflection layer is provided on the surface opposite to the surface on which the parallax image and the light shielding pattern are formed. Can be formed.

  An image display body according to a third aspect of the present invention is characterized in that the image display body according to the first aspect includes a reflective layer formed between the medium and the parallax image.

  According to the image display body of the third aspect, the parallax image can be brightly displayed using the light reflected by the reflection layer, and the reflection layer is provided on the same surface as the surface on which the parallax image and the light shielding pattern are formed. Can be formed.

  The image display body according to a fourth aspect of the present invention is the image display body according to any one of the first to third aspects, wherein the light-shielding pattern is a part where the color of each pixel of the parallax image tends to blur. It is characterized by having a strong light-shielding property as compared with the above part.

  According to the image display body of the fourth aspect, it is possible to prevent a part of one of the left-eye image and the right-eye image from being overlapped and displayed on a part of the other image. .

Yes.

  According to the image display body of the fifth aspect, since the light shielding pattern is a vertical stripe pattern, the parallax image is likely to be brighter than the light shielding pattern of the step barrier method. The contrast of the parallax image obtained can be set high. Furthermore, since the degradation of resolution is evenly distributed in the vertical and horizontal directions, it is possible to suppress the degradation of the image quality of the parallax image that can be recognized by the observer as compared with the light shielding pattern of the parallax barrier method.

  Hereinafter, an image display body, a manufacturing method thereof, and a manufacturing program thereof according to the present invention will be described with reference to two embodiments.

  First, an image display 1A according to the first embodiment, a manufacturing method thereof, and a manufacturing program thereof will be described. The image display body 1A of the first embodiment is an image display panel such as a printed matter, electronic paper, or a liquid crystal display, or another object or device that displays an image. The image display 1A includes a transparent medium 2, a parallax image 3, and a light shielding pattern 4 as shown in FIG.

  The transparent medium 2 is a medium 2 formed using a transparent film, a transparent disk, a transparent glass, or other material that transmits light. The light transmittance and color presence / absence of the transparent medium 2 are not particularly specified as long as the light is transmitted through the transparent medium 2. The transparent medium 2 has a smooth surface and a back surface. This “smoothing” is only required to be smooth to the extent that the parallax image 3 can be recognized, and a high-precision smoothing level is not required. The thickness from the front surface to the back surface of the transparent medium 2 is set to L1.

  As shown in FIG. 1A, the parallax image 3 is formed on one surface (for example, the back surface) of the front surface and the back surface of the transparent medium 2. The parallax image 3 includes a left-eye image and a right-eye image. These left-eye image and right-eye image are provided so that the parallax image 3 through the light-shielding pattern 4 can be seen as a stereoscopic image from the observer.

  Here, when the image display 1A is a printed material, the parallax image 3 is formed using inks of various colors such as CMYK. When the image display body 1A is an image display panel, the parallax image 3 is a color layer such as a color filter layer.

  Further, as the arrangement pattern of the left eye image L and the right eye image R, the vertical stripe pattern type shown in FIG. 2A (the orthogonal direction with respect to the straight line connecting the left eye and the right eye is the vertical direction). And houndstooth type shown in FIG. 2B. Here, the line widths of the left eye image L and the right eye image R in the vertical stripe pattern type may be the same width a. Further, the grid size of the left-eye image L and the right-eye image R in the staggered grid type may be the same width a in both the vertical and horizontal directions.

  As shown in FIG. 1A, the light shielding pattern 4 (see FIG. 3) is formed on the other surface of the surface and the back surface of the transparent medium 2 on which the parallax image 3 is formed. As shown in FIGS. 4A and 4B or FIGS. 5A and 5B, the light-shielding pattern 4 is separated into a left-eye image L and a right-eye image R.

  Here, when the image display 1 </ b> A is a printed material, the light shielding pattern 4 is formed using an ink having a low light transmittance such as a black ink. When the image display body 1A is an image display panel, the light shielding pattern 4 may be a transmittance adjusting layer such as a liquid crystal filter layer.

  In addition, as the pattern method of the light shielding pattern 4, there are mainly two types, that is, a parallax barrier method shown in FIG. 3A and a step barrier method shown in FIG. These formats may be set according to what the display target of the parallax image 3 is.

  For example, when the display target of the parallax image 3 is mainly a character, a symbol, or other planar object such as a newspaper or TV news image, the pattern method of the light shielding pattern 4 may be a parallax barrier method. On the other hand, when the display target of the parallax image 3 is mainly a landscape or a person or other three-dimensional object such as a landscape, a person, a building, or a machine, the pattern method of the light shielding pattern 4 may be a step barrier method. The purpose of “mainly” is that the display target of the parallax image 3 is rarely only a flat object or a three-dimensional object, and light is blocked depending on whether the main display object is a flat object or a three-dimensional object. The pattern method of pattern 4 may be set.

  The inter-pattern distance X in the light shielding pattern 4 is the thickness L1 of the transparent medium 2 that is the distance between the parallax image 3 and the light shielding pattern 4, and the observation distances L2 and L3 that are the distance from the observer to the light shielding pattern 4. And the image width a of the parallax image 3 is set. As shown in FIGS. 1A and 1B, when the observer observes from the light shielding pattern 4 side (the surface side of the transparent medium 2), the light shielding is performed when the distance from the observer to the light shielding pattern 4 is L2. The inter-pattern distance X in the pattern 4 is set to 0 <X ≦ a · L2 / (L2 + L1). On the other hand, when the observer observes from the parallax image 3 side (the back side of the transparent medium 2), when the distance from the observer to the light shielding pattern 4 is L3, the inter-pattern distance X in the light shielding pattern 4 is 0 < X ≦ a · L3 / (L3−L1) is set.

  Note that the thickness of the parallax image 3 and the thickness of the light shielding pattern 4 are negligible values compared to the thickness L1 and the observation distance L2 of the transparent medium 2, and therefore, in calculating the inter-pattern distance X, these thicknesses are used. 0.

  In addition, the light shielding pattern 4 may have a strong light shielding property in a portion where the color in each of the left-eye image L or the right-eye image R of the parallax image 3 is likely to blur as compared with other portions. For example, when the image display body 1 is a printed matter, the characteristics of the printer that printed the printed matter (for example, in the case of an ink jet printer, the ink bleeds out where ink from a nozzle that causes more ink to eject than other nozzles lands. The area where bleeding is likely to occur is known in advance, so that in the area where bleeding is likely to occur, the light-shielding pattern 4 is darkened (the amount of black ink is increased compared to other areas). It may be strong.

  As shown in FIG. 6, the reflective layer 5 is formed on the surface opposite to the transparent medium 2 in the parallax image 3. The reflection layer 5 reflects light incident on the parallax image 3 via the transparent medium 2. The reflection layer 5 may be a layer formed of a material that reflects light. For example, a layer formed by printing with a reflective ink such as a metallic ink is used.

  Next, a manufacturing program for the image display 1A according to the first embodiment will be described. The image display body 1 </ b> A of the first embodiment is manufactured by the image display body manufacturing apparatus 14. As shown in FIG. 7, the image display body manufacturing apparatus 14 is connected to an information processing apparatus 11 in which a manufacturing program for the image display body 1A is installed. And the manufacturing program of the image display body 1A of 1st Embodiment performs the manufacturing method of 1 A of image displays of 1st Embodiment by operation | movement of the information processing apparatus 11. FIG.

  As an example, the image display body manufacturing apparatus 14 is a printing apparatus such as a printer if the image display body 1A is a printed matter, and the image display panel if the image display body 1A is an image display panel such as an electronic paper or a liquid crystal display. An image engine built in the image display device for displaying an image on the screen.

  As shown in FIG. 7, the information processing apparatus 11 includes a storage device 13 and a processing device 12, and is connected to the inside or the outside of the image display body manufacturing apparatus 14. The storage device 13 stores the above-described manufacturing program, and the processing device 12 performs the manufacturing process according to the manufacturing method of the image display body 1A based on the manufacturing program stored in the storage device 13, thereby the image display body manufacturing apparatus. 14 is operated.

  Next, a manufacturing method of the image display body 1A of the first embodiment will be described. In the manufacturing method of the image display body 1A of the first embodiment, the parallax image forming step shown in FIG. 8A and the light shielding pattern forming step shown in FIG. The parallax image forming step and the light shielding pattern forming step may be performed from either step. Further, when the image display body 1 having the reflective layer 5 shown in FIG. 6 is generated, in the manufacturing method of the image display body 1A of the first embodiment, the reflective layer forming process is further performed after the parallax image forming process. (FIG. 8A).

  In the parallax image forming step, as shown in FIG. 8A, the parallax image 3 is formed on one surface (for example, the back surface) of the front surface and the back surface of the transparent medium 2. For example, when the image display body 1 </ b> A is a printed material, the parallax image 3 is formed by ink of each color ejected from the head 14 a of the printing apparatus serving as the image display body manufacturing apparatus 14. The image display body manufacturing apparatus 14 may form the reflective layer 5 on the parallax image 3 after forming the parallax image 3.

  In the light shielding pattern forming step, the light shielding pattern 4 is formed on the other surface (for example, the front surface) of the front surface and the back surface of the transparent medium 2 as shown in FIG. For example, when the image display body 1A is a printed material, the light shielding pattern 4 is formed of a low transmittance ink such as a black ink ejected from the head 14a. Further, the light shielding degree of the light shielding pattern 4 is controlled by the amount of applied black ink.

  At this time, the image width a of the left-eye image and the right-eye image and the inter-pattern distance X in the light shielding pattern 4 are 0 <X ≦ a · L2 / (L2 + L1) in FIG. 1 or 0 <X ≦. a · L3 / (L3−L1) is printed.

  In the reflective layer forming step, the reflective layer 5 is formed on the opposite surface of the parallax image 3 from the transparent medium 2 as shown in FIG. For example, when the image display body 1 </ b> A is a printed material, the reflective layer 5 is formed by metallic ink ejected from the head 14 a of the printing apparatus serving as the image display body manufacturing apparatus 14.

  Next, the operation of the image display 1A of the first embodiment, its manufacturing method, and its manufacturing program will be described.

  In the image display body 1A of the first embodiment, as shown in FIG. 1A, the parallax image 3 or the light shielding pattern 4 is formed on the front and back surfaces of the transparent medium 2, and the parallax image 3 and the light shielding pattern are formed. The inter-pattern distance X of the light shielding pattern 4 as described above is set based on the thickness L1 and the observation distance L2 of the transparent medium 2 and the image width a of the parallax image 3 that are distances between . Therefore, the observer can observe only the image for the left eye with the left eye and can observe only the image for the right eye with the right eye. As a result, the observer can three-dimensionally recognize the image displayed on the image display body 1A. Furthermore, the observer can recognize a stereoscopic image when viewing the image display body 1A of the present embodiment from either the front surface or the back surface.

  Further, the light shielding pattern 4 of the image display body 1A of the first embodiment is a color in each left-eye image L or right-eye image R of the parallax image 3 as shown in FIG. 1 (A) or (D). It may have a locally strong light-shielding property at a place where the ink is easily blurred. Thereby, it is possible to prevent a part of one of the left-eye image and the right-eye image from being overlapped and displayed on a part of the other image. A clear image can be recognized.

  Moreover, the image display body 1A of the first embodiment may include a reflective layer 5 on the surface opposite to the transparent medium 2 in the parallax image 3 as shown in FIG. Thereby, the parallax image 3 can be displayed brightly using the light reflected by the reflective layer 5.

  Here, when the display target of the parallax image 3 is mainly characters, symbols, or other planar objects, the pattern method of the light shielding pattern 4 of the image display body 1A of the first embodiment is as shown in FIGS. As shown in FIG. 4A and FIGS. 4A and 4B, a parallax barrier method may be used. Since the parallax barrier light shielding pattern 4 is a striped pattern in the vertical direction, the parallax image 3 tends to be brighter than the step barrier light shielding pattern 4. As a result, it is possible to set the contrast of the parallax image 3 whose main display target is characters or the like to be high.

  On the other hand, when the display target of the parallax image 3 is mainly a landscape or a person or other three-dimensional object, the pattern method of the light shielding pattern 4 of the image display body 1A of the first embodiment is as shown in FIGS. As shown in FIG. 5B and FIGS. 5A and 5B, a step barrier method may be used. Since the step barrier light shielding pattern 4 is evenly distributed in resolution in the vertical and horizontal directions, the image quality degradation of the parallax image 3 that can be recognized by the observer is lower than that of the parallax barrier light shielding pattern 4. Can be suppressed.

  Moreover, in the manufacturing method of the image display body 1A of 1st Embodiment, as shown in FIG.7 and FIG.8 (A) and (B), based on the manufacturing program of 1st Embodiment, it showed above. A parallax image forming step and a light shielding pattern forming step are executed. Therefore, similarly to the above, since the light-shielding pattern 4 having a suitable inter-pattern distance X is formed, the manufacturing method of the image display body 1A of the first embodiment is to manufacture the image display body 1A. The manufacturing program of the first embodiment can cause the manufacturing apparatus to manufacture the image display body 1A.

  Next, an image display body 1B of the second embodiment, a manufacturing method thereof, and a manufacturing program thereof will be described. As shown in FIG. 9A, the image display body 1B of the second embodiment includes a medium 2, a parallax image 3, a transparent layer 6, and a light shielding pattern 4.

  The difference from the first embodiment is that the parallax image 3 and the light shielding pattern 4 are formed on the same surface side of the medium 2, and the transparent layer 6 is interposed between the parallax image 3 and the light shielding pattern 4. It is that you are.

  The medium 2 has a smooth surface. Unlike the first embodiment, being transparent is not an essential condition.

  The parallax image 3 is formed on the surface of the medium 2. Similar to the above, the parallax image 3 has a left-eye image and a right-eye image, and the width of each image is set to a.

  The transparent layer 6 is formed on the surface of the parallax image 3. And the thickness of the transparent layer 6 is set to L1. In the function of setting the distance between the parallax image 3 and the light shielding pattern 4 to L1, the transparent layer 6 plays the same role as the transparent medium 2 of the first embodiment.

  The light shielding pattern 4 is formed on the surface of the transparent layer 6. The role of the light shielding pattern 4, the pattern method such as the parallax barrier method and the step barrier method, the inter-pattern distance X, and the light shielding property of the light shielding pattern 4 are set as in the first embodiment.

  Further, the image display body 1 </ b> B of the second embodiment may further include a reflective layer 5. For example, as shown in FIG. 10 or FIG. 11, the reflective layer 5 is formed between the medium 2 and the parallax image 3 or on the back surface of the medium 2. As shown in FIG. 11, when the reflective layer 5 is formed on the back surface of the medium 2, it is an essential condition that the medium 2 is transparent.

  Further, in the present embodiment, the reflective layer 5 may not be formed at a location where the color in the left-eye image L or the right-eye image R of the parallax image 3 is likely to blur. This is to prevent the color blur from becoming noticeable. “Easy to blur” is the same as in the first embodiment.

  Next, a manufacturing program for the image display body 1B of the second embodiment will be described. The image display body 1B of the second embodiment is manufactured by the image display body manufacturing apparatus 14 as in the first embodiment. And the manufacturing program of the image display body 1B of 2nd Embodiment performs the manufacturing method of the image display body 1B of 2nd Embodiment by operation | movement of the information processing apparatus 11 connected to the image display body manufacturing apparatus 14. FIG. To do.

  Next, the manufacturing method of the image display body 1B of 2nd Embodiment is demonstrated. In the manufacturing method of the image display body 1B of the second embodiment, as shown in FIGS. 12A, 12B, and 12C, the parallax image forming step, the transparent layer forming step, and the light shielding pattern forming step are performed as follows. Executed in order. Further, as shown in FIG. 10, in the method of manufacturing the image display body 1B including the reflective layer 5 between the parallax image 3 and the medium 2, the reflection is performed before the parallax image forming step as shown in FIG. A layer forming step is performed. As shown in FIG. 11, the manufacturing method of the image display body 1B including the reflective layer 5 on the back surface of the parallax image 3 includes a reflective layer forming step as shown in FIG.

  In the parallax image forming step, the parallax image 3 is formed on the surface of the medium 2 or the surface of the reflective layer 5 as shown in FIG. The parallax image 3 is formed using, for example, ink of each color ejected from the head 14a according to the image display body manufacturing apparatus 14. The parallax image forming step is almost the same as that in the first embodiment.

  In the transparent layer forming step, the transparent layer 6 is formed on the surface of the parallax image 3 as shown in FIG. The transparent layer 6 is formed using, for example, transparent ink such as clear ink discharged from the head 14a.

  In the light shielding pattern forming step, the light shielding pattern 4 is formed on the surface of the transparent layer 6 as shown in FIG. The light shielding pattern 4 is formed using, for example, black ink ejected from the head 14 a according to the image display body manufacturing apparatus 14. The light shielding pattern forming step is generally the same as in the first embodiment.

  In the reflective layer forming step, the reflective layer 5 is formed on the front surface or the back surface of the medium 2 as shown in FIG. The reflective layer 5 is formed using, for example, transparent ink such as metallic ink ejected from the head 14a. As shown in FIG. 12A, when the reflective layer 5 is formed on the surface of the medium 2, the reflective layer forming step is performed before the parallax image forming step. On the other hand, as shown in FIG. 13, when the reflective layer 5 is formed on the back surface of the medium 2, the reflective layer forming step is any of the parallax image forming step, the transparent layer forming step, and the light shielding pattern forming step. It may be performed before and after.

  When the image display body 1B is generated, the medium 2 is fed in the sub-scanning direction orthogonal to the main scanning direction in which the head 14a of the printing apparatus reciprocates, while the media 2 in FIGS. 12A, 12B, and 12C. Each process is performed in order. Therefore, the head 14a has a structure as shown in FIG. 14, for example.

  That is, FIG. 14 shows a view of the nozzle surface of the head 14a as seen from the front. As shown in the figure, the head 14a includes a nozzle group 141 that ejects metallic ink that forms the reflective layer 5, a nozzle group 143 that ejects color ink that forms the parallax image 3, and a transparent ink that forms the transparent layer 6. A nozzle group 145 for discharging and a nozzle group 147 for discharging black ink 4 for forming the light shielding pattern 4 are provided. Each nozzle group 141, 143, 145, 147 is arranged along the sub-scanning direction in which the medium 2 is sent. By using this head 14a, in order to form the reflective layer 5, the parallax image 3, the transparent layer 6 and the light shielding pattern 4 on the medium 2, it is not necessary to send the medium 2 in the sub-scanning direction multiple times. The reflective layer 5, the parallax image 3, the transparent layer 6, and the light shielding pattern 4 can be laminated on the medium 2 in this order. In this way, the parallax image 3 and the light shielding pattern 4 can be stacked and formed on the same surface of the medium 2 in one sub-scan, so that the relative alignment between the parallax image 3 and the light shielding pattern 4 can be performed with high accuracy. It can be carried out.

  Next, the operation of the image display body 1B of the second embodiment, its manufacturing method, and its manufacturing program will be described.

  In the image display 1 </ b> B of the second embodiment, the parallax image 3, the transparent layer 6, and the light shielding pattern 4 are sequentially stacked on the surface of the medium 2.

  Here, the inter-pattern distance X in the light shielding pattern 4 is set to a suitable allowable range based on the thickness L1 and the observation distance L2 of the transparent layer 6 and the image width a of the parallax image 3 as in the first embodiment. In this case, the observer can observe only the image for the left eye with the left eye, can observe only the image for the right eye with the right eye, and can recognize the image three-dimensionally. Furthermore, if the medium 2 is transparent, the observer can recognize a stereoscopic image when viewing the image display body 1B from either the front surface or the back surface.

  Further, when the reflective layer 5 is formed on the back surface of the transparent medium 2 or between the medium 2 and the parallax image 3, the parallax image 3 can be brightly displayed using the light reflected by the reflective layer 5. . In addition, the reflective layer 5 can be formed on the surface opposite to the surface on which the parallax image 3 and the light shielding pattern 4 are formed, or the reflective layer 5 is formed on the same surface as the surface on which the parallax image 3 and the light shielding pattern 4 are formed. Therefore, the degree of freedom in designing the image display body 1B can be improved.

  In addition, the reflective layer 5 of the image display body 1B of the second embodiment is formed on portions of the parallax image 3 other than the portions where the colors in the left-eye image L or the right-eye image R tend to blur. May be. Thereby, since the reflected light from the reflective layer 5 can be reduced with respect to the part in which the color in each left-eye image L or the right-eye image R of the parallax image 3 is easy to blur, the blur can be made inconspicuous. .

  Further, the difference in the light shielding property and pattern method of the light shielding pattern 4 in the image display body 1B of the second embodiment, and the operation relating to the manufacturing method and the manufacturing program of the image display body 1B of the second embodiment are as follows. The same operation as the above-described operation in the embodiment or the second embodiment is shown.

  That is, according to the image display body of the present embodiment, only one of the left-eye image and the right-eye image is suitably applied to one eye of the observer by the light shielding pattern 4 and the reflective layer 5. Since it can be displayed, there is an effect that a stereoscopic image or the like can be suitably displayed without using a lenticular lens that tends to increase the manufacturing cost.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed. For example, in the above description, a preferred embodiment for displaying a stereoscopic image has been described. However, in addition to this, it is also possible to apply when displaying two different images, such as a dual display.
