Description

  The present invention relates to a method for manufacturing a binocular parallax-applied stereoscopic image sheet structure and a binocular parallax-applied stereoscopic image sheet structure. More specifically, the binocular parallax-applied stereoscopic image composite image and a convex lens assembly are accurately and easily obtained. Manufacturing method of a binocular parallax application stereoscopic image sheet structure that can be registered with a binocular parallax application stereoscopic image and a binocular parallax application stereoscopic image in which a composite image for a binocular parallax application stereoscopic image and a convex lens assembly are accurately registered The present invention relates to a seat structure.

  For example, a stereoscopic sheet using a lenticular lens or an itegral using a microarray lens can obtain a three-dimensional visual effect by utilizing the parallax of an observer without using a specific instrument such as glasses. Photography (referred to as IP in this invention) stereoscopic sheet and the like. These stereoscopic sheets are usually produced by directly printing a stereoscopically visible image on the back surface of the lenticular lens or microarray lens, or by laminating a sheet on which a stereoscopically visible image is printed with the lenticular lens or microarray lens. It is produced by sticking or fusing.

  These three-dimensional sheets are formed in a desired three-dimensional image as long as the lenticular lens or microarray lens and the three-dimensional image (printed on the sheet) are not accurately arranged at predetermined positions. It cannot be seen, and the image quality deteriorates. Therefore, in the stereoscopic sheet, the positional relationship between the lenticular lens or the microarray lens and the stereoscopically viewable image is important. In particular, in order to obtain a sufficient three-dimensional visual effect, an integral photography stereoscopic sheet using a microlens array has a horizontal position between the lens position of the microarray lens and the arrangement position of the sections constituting a stereoscopically viewable image. It is necessary to accurately match both the direction and the vertical method and the tilt angle.

  However, the alignment of the lenticular lens or the microarray lens and the stereoscopically viewable image (referred to as registration in this invention) is performed by, for example, superimposing the lenticular lens or the microarray lens on the stereoscopically viewable image. While relatively moving one of them, the position where the position of the lenticular lens or the microarray lens and the position where the stereoscopically viewable image is considered to coincide is determined sensuously. This registration is also possible by printing a stereoscopically visible image on the back of the lenticular lens or microarray lens, observing the image printed through the lenticular lens or microarray lens, and stereoscopically visible with the lenticular lens or microarray lens. This was done by sensuously judging the position where the position of the correct image would match.

  As described above, registration of a conventional lenticular lens or microarray lens and a stereoscopically viewable image is performed by repeating trial and error, which requires a long time and high cost for positioning, and is a skillful technique. Was requested.

From the above, the binocular parallax-applied stereoscopic image composition with respect to the convex lens assembly is performed by an easy determination method of determining whether or not the first region designation position of the registration unit matches the position in the lens formation section of the convex lens assembly. The arrangement position of the image can be determined accurately and easily. Therefore, according to the present invention, it is possible to provide a method for manufacturing a binocular parallax-applied stereoscopic image sheet structure capable of accurately and easily registering a binocular parallax-applied stereoscopic image composite image and a convex lens assembly. it can.

  In addition, the binocular parallax applied stereoscopic image sheet structure manufactured by the manufacturing method according to the present invention has the initial positions since the positions of the convex lens assembly and the binocular parallax applied stereoscopic image composite image sheet are accurately adjusted. The stereoscopic effect is fully exhibited.

  The binocular parallax-applied stereoscopic image sheet structure manufacturing method according to the present invention is for a binocular parallax-applied stereoscopic image having a convex lens assembly and a registration part inside or around a composite image part for binocular parallax-applied stereoscopic image. The composite image is arranged in a state where a predetermined positional relationship is maintained by using the registration unit and the convex lens.

  In the method for manufacturing a binocular parallax applied stereoscopic image sheet structure according to the present invention, a convex lens assembly is prepared. As shown in FIG. 1, a convex lens assembly 10 as an example of a convex lens assembly includes a convex lens 12 that focuses on one surface 13 of a sheet member 11 on the other surface 14 or on the same plane behind the surface 14. It is arranged. The sheet member 11 may be composed of one sheet or a plurality of sheets. The thickness of the sheet member 11 is substantially the same length as the focal length of the convex lens 12 or shorter than the focal length. In other words, when the convex lens 12 is disposed on one surface 13 of the sheet member 11, the convex lens 12 focuses on the other surface 14 of the sheet member 11, or the other surface of the sheet member 11. The thickness of the sheet member 11 is determined so as to focus on the same plane behind 14. In general, the thickness of the sheet member 11 is adjusted to 0.1 to 10.0 mm according to the focal length of the convex lens 12 and is preferably adjusted to 0.1 to 0.8 mm. The shape of the sheet member 11 may be a shape that can support the convex lens 12, and may be a plate shape such as a planar shape, a curved surface shape, or an arbitrary uneven shape.

  The convex lens assembly 10 has a plurality of convex lenses 12 formed on the surface 13 of the sheet member 11. The arrangement of the convex lenses 12 is characterized by the arrangement of lens forming sections 15 (see FIG. 2 and the like) in which one convex lens 12 is formed, the interval between the lens forming sections 15 and the like. Examples of the shape of the lens forming section 15 include a polygon such as a quadrangle and a hexagon, a circle, and a parallel line. The lens forming section 15 has one convex lens 12 formed therein, and determines the arrangement of the convex lenses 12. The size of the lens forming section 15 (the interval between adjacent lens forming sections 15) is determined according to the arrangement interval L of the convex lenses 12 described later. Examples of the arrangement of the convex lenses 12 include the arrangements shown in FIGS. The array of the convex lenses 12 shown in FIG. 2 is a honeycomb-shaped array in which one convex lens 12 is formed in each of the regular hexagonal lens forming sections 15 arranged in a close-packed manner. The arrangement of the convex lenses 12 shown in FIG. 3 is a square-shaped arrangement in which one convex lens 12 is formed in each of the regular rectangular lens forming sections 15 arranged vertically and horizontally. The arrangement of the convex lenses 12 shown in FIG. This is a square array in which one convex lens 12 is formed in each of regular square pattern forming sections 15 rotated 45 degrees and arranged vertically and horizontally.

  The convex lens 12 is formed in the lens forming section 15, preferably substantially in the center thereof. The shape of the convex lens 12 may be any shape that can focus the light incident on the convex lens 12. The size of the convex lens 12 may be equal to or smaller than the size of the lens forming section 15, and is particularly preferably the same as the size of the lens forming section 15. The height of the convex lens 12 is not limited as long as the light incident on the convex lens 12 can be focused on the other surface 14 of the sheet member 11 or the same plane behind the surface 14 and is, for example, about 5 to 500 μm.

  The convex lenses 12 are arranged with an arrangement interval L between the convex lenses 12 adjacent to each other in the arrangement direction of the lens forming sections 15. The arrangement interval L of the convex lenses 12 at this time may be equal or different, and is not particularly limited. The arrangement interval L between the convex lenses 12 is, for example, preferably about 0.1 to 1.2 mm, and particularly preferably about 0.12 to 0.42 mm. The arrangement interval L of the convex lenses 12 refers to a distance from an arbitrary position of a certain convex lens 12 to a position corresponding to the arbitrary position of the convex lens 12 adjacent thereto in the arrangement direction of the lens forming sections 15. For reference, the arrangement interval L between the centers of the convex lenses 12 in the arrangement shown in FIGS. 2 to 4 is shown in each drawing.

  The convex lens assembly 10 having such a configuration may be a commercially available convex lens sheet or may be manufactured. Since the binocular parallax-applied stereoscopic image sheet structure according to the present invention observes a binocular parallax-applied stereoscopic image composite image via a convex lens assembly, the sheet member 11 needs to be transparent. Here, “transparent” means that the composite image for binocular parallax-applied stereoscopic images can be observed, and includes states of colorless and transparent, translucent, colored and transparent, and colored and translucent. It is a concept. Therefore, the sheet member 11 is formed of a transparent material such as synthetic resin, glass, or a transparent coating film by a known manufacturing method such as a molding technique. At this time, it is preferable that the surface 13 on which the convex lens 12 is disposed in the sheet member 11 is as smooth as possible. Before the convex lens 12 is formed, the surface 13 may be surface-treated according to a standard method, or an underlayer may be provided. May be. The underlayer can be formed by using a resin composition or the like by dipping, brushing, spraying, coating with a roll coater, printing, or other methods. Next, a material that functions as the convex lens 12, for example, an acrylic ester resin such as methyl acrylate resin, a methacrylic ester resin such as methyl methacrylate resin or a vinyl resin, or a resin composition containing these resins The convex lens 12 is formed on the surface 13 of the sheet member 11. Examples of the method for forming the convex lens 12 include a molding method using a mold and a printing method.

  When the sheet member 11 and the convex lens 12 are formed of the same material, the sheet member 11 and the convex lens 12 can be integrally formed by, for example, a molding technique.

  Further, a convex lens assembly 50 as another example of a convex lens assembly prepared in the method for manufacturing a binocular parallax applied stereoscopic image sheet structure according to the present invention includes one of sheet members 51 as shown in FIG. This is a lenticular lens in which a convex lens 52 having a substantially semicircular arc-shaped cross section focusing on the other surface 54 or the same plane behind the surface 54 is disposed on the surface 53 of the lens. The lenticular lens is a known lens, and an appropriate lens can be used. For example, the shape of the lens forming section in the convex lens assembly 50 includes a rectangle extending in one direction composed of a plurality of parallel lines. The height of the convex lens 52 in the convex lens assembly 50 may be such that the light incident on the convex lens 52 can be focused on the other surface 54 of the sheet member 51 or on the same plane behind the surface 54, for example, about 5 to 500 μm. It is. Other characteristics such as the thickness of the sheet member 51 in the convex lens assembly 50 and the arrangement interval in the convex lens 52 can be set similarly to the convex lens assembly 10, for example. The convex lens assembly 50 may be a commercially available convex lens sheet or may be manufactured.

  In the method for producing a binocular parallax applied stereoscopic image sheet structure according to the present invention, a binocular parallax applied stereoscopic image composite image having a registration part inside or around a binocular parallax applied stereoscopic image composite image is prepared. To do. The composite image for binocular parallax applied stereoscopic image will be described later.

  In the binocular parallax-applied stereoscopic image sheet structure manufacturing method according to the present invention, the convex lens assembly and the binocular parallax-applied stereoscopic image composite image are registered using a registration lens and a convex lens positioned above the registration unit. Thus, they are arranged in a state where a predetermined positional relationship is maintained. The predetermined positional relationship will be described later. The binocular parallax-applied stereoscopic image sheet structure manufactured in this way is both on the other surface 14 side opposite to the one surface 13 on which the convex lens 12 of the sheet member 11 of the convex lens assembly 10 is arranged. A composite image for stereoscopic images applied with eye parallax is arranged.

  According to the binocular parallax-applied stereoscopic image sheet structure manufacturing method according to the present invention, the binocular parallax-applied stereoscopic image composite image includes the registration unit having the first region and the second region having different densities. From the method described later, for example, a method of relatively moving the convex lens assembly 10 while observing the registration portion via the convex lens 12, a method of printing a binocular parallax applied stereoscopic image composite image on the convex lens assembly 10, and the like. By using this method, the binocular to the convex lens assembly 10 is determined by an easy determination method of determining whether or not the first region designation position of the registration portion matches the position in the lens formation section of the convex lens assembly 10. The arrangement position of the composite image for parallax applied stereoscopic images can be determined accurately and easily. Therefore, according to the present invention, a method for producing a binocular parallax-applied stereoscopic image sheet structure capable of accurately and easily registering a binocular parallax-applied stereoscopic image and the convex lens assembly 10 is provided. Can do.

  About the manufacturing method of the binocular parallax application stereoscopic image sheet structure of the first aspect in the manufacturing method of the binocular parallax application stereoscopic image sheet structure according to the present invention (hereinafter sometimes referred to as the manufacturing method of the first aspect). This will be described with reference to the drawings. In the manufacturing method of the first aspect, as an example of the binocular parallax applied stereoscopic image sheet structure 1 to be manufactured, the opposite side to the one surface 13 on which the convex lens 12 in the sheet member 11 of the convex lens assembly 10 is arranged. The structure 1 in which the binocular parallax applied stereoscopic image composite image sheet 30 is arranged on the other surface 14 is shown in FIG. The convex lens assembly 10 in the manufacturing method of the first aspect is as described above.

  In the manufacturing method of the first aspect, a binocular parallax applied stereoscopic image composite image sheet 30 is produced. As shown in FIG. 5, the binocular parallax applied stereoscopic image composite image sheet 30 includes one binocular parallax applied stereoscopic image composite image portion 32 positioned substantially at the center on one surface of the sheet member 31. The binocular parallax-applied stereoscopic image composite image portion 32 surrounds the peripheral portion 33 and inside the peripheral portion 33, the four portions formed on the top, bottom, left and right of the binocular parallax-applied stereoscopic image composite image portion 32. And a register part 35.

  In the binocular parallax-applied stereoscopic image composite image portion 32, unit images (unit images similar to the unit images 36 of the peripheral portion 33 shown in FIG. 6) that can be visually recognized through the convex lens 12 are arranged with the arrangement interval L of the convex lenses 12. Alternatively, a large number are arranged in the same manner as the convex lens 12 at an arrangement interval slightly larger than the arrangement interval L. The binocular parallax-applied stereoscopic image composite image unit 32 is an original image obtained with N parallaxes that are equal to the number N of divisions of the unit image that can be visually recognized through the convex lens 12. The images are synthesized according to a binocular parallax-applied stereoscopic image synthesis method, for example, an integral photography image synthesis method. The method for synthesizing the integral photography image will be described in the manufacturing method according to the third aspect of the present invention.

  The peripheral part 33 is an area provided so as to surround the binocular parallax-applied stereoscopic image composite image part 32 where the binocular parallax-applied stereoscopic image composite image is not formed. In the peripheral portion 33, a registration portion 35 serving as a mark for registration between the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 is formed. As shown in FIG. 5, the registration unit 35 is formed on each of the upper, lower, left, and right sides of the binocular parallax applied stereoscopic image composite image unit 32 in the peripheral unit 33. As shown in FIG. 5, the registration unit 35 has a part of the peripheral portion 33 positioned on the top, bottom, left, and right of the binocular parallax applied stereoscopic image composite image portion 32, for example, a length of about 5 cm and a width of about 2 cm. It may be formed in a belt-like shape or the like, or may be formed so as to surround the entire peripheral portion 33, that is, so as to surround the binocular parallax applied stereoscopic image composite image portion 32.

  As shown in detail in FIG. 6, the registration unit 35 includes a plurality of unit images 36 each having a first region 37 and a second region 38 having different densities, according to the same arrangement as the convex lens 12. Here, as shown in FIG. 6, the unit image is a binocular parallax applied stereoscopic image that can be viewed through one convex lens 12 when the binocular parallax applied stereoscopic image sheet structure 1 is used. The composite image sheet 1, more precisely, a unit area of the peripheral portion 33, has a size substantially the same as the size of the lens forming section 15 in which the convex lens 12 is formed. The number N of partitions in which the unit image 36 is partitioned is not particularly limited. For example, it is preferable that the number n of the unit images in the vertical direction and the horizontal direction is the same, and therefore, 4, 9, 16,. -It is preferable that it is set to the square of an integer n such as. Therefore, the number of sections into which the unit image is partitioned is N, that is, the unit image is composed of N sections. For example, in the example shown in FIG. 6, each unit image 36 is composed of a total of nine sections divided into three vertical and horizontal sections defined by solid lines (number of sections N = 9).

  As shown in FIG. 6, the first area 37 and the second area 38 are respectively assigned to the arbitrary sections thus partitioned. The position of the partition to which the first region 37 is assigned is not particularly limited. However, when the number N of partitions into which the unit image 36 is partitioned is an odd number, the center partition in each unit image or a plurality including the center partition. In addition, when the number N of divisions into which the unit image 36 is divided is an even number, there are a plurality of divisions extending over the central portion of each unit image or one division adjacent to the central portion. Is preferred. When the first region 37 is assigned to the central section, a plurality of sections including the central section, or a plurality of sections straddling the central section or one section adjacent to the central section, the binocular parallax applied stereoscopic image sheet structure 1 is preferable in that one convex lens 12 can be registered when viewed from the front. That is, for example, the first region 37 is a partition other than a central partition, a partition other than a plurality of partitions including the central partition, or a partition other than a plurality of partitions spanning the central portion or one partition adjacent to the central portion. When the registration is performed, it is necessary to view the binocular parallax application stereoscopic image sheet structure 1 from a specific angle through one convex lens 12 when registering, and accurate registration is possible. However, workability may be sacrificed to some extent. It is sufficient that the first region 37 and the second region 38 have different concentrations.

  As an example of the position of the section to which the first area 37 is assigned, for example, as shown in FIG. 16A, an example in which the first area 37 is assigned to the center section in each unit image 36, FIG. As shown in FIG. 16C, an example in which the first area 37 is assigned in a vertical row including the central section in each unit image 36, as shown in FIG. 16C, the first area 37 is in the center in each unit image 36. And an example in which the first region 37 is assigned to a vertical row and a vertical row including the central zone in each unit image 36, as shown in FIG. 16 (d). Can be mentioned. In these examples, the second region 38 having a lower concentration than the first region 37 is assigned to a partition other than the first region 37, that is, a partition surrounding the first region or a partition adjacent to the first region. ing. The position of the partition to which the first area 37 is allocated may be a position other than these. For example, the first area 37 is allocated by combining at least two of FIGS. 16 (a) to 16 (d). May be.

  The register 35 as an example shown in FIG. 6 is assigned the first area 37 in the same manner as the example shown in FIG. 16A, and specifically, the center of the sections divided into nine sections. The first area 37 is assigned to one of the two sections, the second area 38 is assigned to eight sections surrounding the central section among the sections divided into nine sections, and the first area 37 is the second area 38. It has a concentration higher than the concentration of.

  Each section formed by dividing the unit image 36 may be composed of only one pixel, or may be composed of a pixel aggregate in which a plurality of pixels are aggregated. For example, the size of the convex lens 12 and the periphery The number of pixels contained in each section is appropriately determined depending on the size of the portion 33 and the like. Each section may be entirely the first area 37 or the second area 38, and only one part of each section is the first area 37 or the second area as shown in FIG. It may be 38. Furthermore, in the example shown in FIG. 6, the shape of the first region 37 or the second region 38 is the same as the shape of the assigned section, but the shape of the first region 37 or the second region 38. Is not limited to the same rectangle as the shape of the allocated section, and may be an arbitrary shape, for example, a circle, an ellipse, a polygon, a crosshair, or the like.

  Such a registration unit 35 is configured by arranging a plurality of unit images 36 that can be visually recognized through one convex lens 12, and assigning a first region 37 and a second region 38 having different densities in the unit image 36. For example, a binocular parallax-applied stereoscopic image is obtained from an image having pixel-divided divided sections rearranged in the first area 37 and an image having pixel-divided divided sections rearranged in the second area 38. And, for example, an integral photography image synthesis method. When the registration unit 35 is created by the integral photography image synthesis method, an original image having a peripheral image capable of forming the registration unit 35 is prepared, and the binocular parallax application stereoscopic image is used. The composite image unit 32 may be created at the same time, and an original image capable of forming the binocular parallax applied stereoscopic image composite image unit 32 and a peripheral image capable of forming the registration unit 35 are prepared. And may be created separately.

  In this manner, a binocular parallax applied stereoscopic image synthesized image including the desired binocular parallax applied stereoscopic image synthesized image unit 32 and the registration unit 35 is created, and this binocular parallax applied stereoscopic image synthesized image is created. An image is formed on one surface of the sheet member 31 by printing or the like, and a binocular parallax applied stereoscopic image composite image sheet 30 is created.

  In the manufacturing method of the first aspect, the arrangement position of the binocular parallax applied stereoscopic image composite image sheet 30 with respect to the convex lens assembly 10 is then determined. That is, in all the registration parts 35 formed on the upper, lower, left and right sides of the binocular parallax applied stereoscopic image composite image part 32, the first area designated position where the first area 37 is assigned in the unit image, and the unit In the lens forming section 15 where one convex lens 12 positioned on the image is formed, the lens forming section position defined at the position corresponding to the first region designated position in the unit image matches. Next, the positional relationship between the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 is determined. More specifically, referring to FIGS. 6 and 7, the first region designation position is assigned with the first region 37 in each unit image 36 constituting the registration unit 35 as shown in FIG. 6. The position, that is, the position occupied by the central section 37 in each unit image 36. On the other hand, as shown in FIG. 7, the position in the lens forming section is the same as the unit image 36 in the registering section 35 in the lens forming section 15 where the convex lenses 12 arranged in the convex lens assembly 10 are formed. Assuming that the image is defined, that is, a total of 9 sections in the vertical and horizontal directions, the position (section) in the unit image 36 to which the first region designation position 37 is assigned in the defined lens forming section 15. ) 37 (virtual section), that is, the position occupied by the central virtual section 16 in each lens forming section 15. And in all the registration parts 35 formed in the upper, lower, left, and right sides of the binocular parallax applied stereoscopic image composite image part 32, the positional relationship in which the first region designation position 37 and the lens forming section position 16 substantially coincide, in other words Then, the positional relationship between the convex lens assembly 10 and the binocular parallax-applied stereoscopic image composite image sheet 30 is determined so that the first region designation position and the position in the lens formation section overlap vertically.

  In order to determine the positional relationship, for example, the convex lens assembly 10 is placed on the binocular parallax applied stereoscopic image composite image sheet 30 and the convex lens assembly 10 is combined with the binocular parallax applied stereoscopic image composite image sheet 30. Relative to, for example, the vertical (vertical) direction, the horizontal (horizontal) direction, and / or the rotational (tilting) direction. During or after the movement of the convex lens assembly 10, an appropriate method, for example, the registration unit 35 and the convex lens assembly 10 are watermarked from the back side of the binocular parallax applied stereoscopic image composite image sheet 30, and a watermark such as irradiation as desired. A method of observing the first region designation position and the lens formation section position with a magnifying glass such as a magnifying glass or the like using an auxiliary means, or the first region designation position from the convex lens 12 side via the convex lens 12 The arrangement position is determined by visual observation or a method of observing with a magnifier such as a magnifying glass.

  In the manufacturing method according to the first aspect, the position determination method for determining the positional relationship in which the first region designation position and the position in the lens formation section substantially coincide with each other is the first of the above methods through the convex lens 12 from the convex lens 12 side. The position determination method for observing one region designated position with a magnifying glass such as a visual or loupe is a positional relationship in which the first region designated position and the lens forming section position substantially coincide with each other, that is, both with respect to the convex lens assembly 10. This is preferable in that the arrangement position of the composite image sheet 30 for the stereoscopic image for eye parallax application can be accurately and easily determined. According to this position determination method, in all the registration units 35 formed on the upper, lower, left, and right sides of the binocular parallax applied stereoscopic image composite image unit 32, the registration unit is interposed via the convex lens 12 positioned on the registration unit 35. Binocular parallax with respect to the convex lens assembly 10 so that when the lens 35 is viewed, almost the entire surface of the convex lens 12 positioned on the registration portion 35 appears to be the darkest density almost the same as the density of the first region 37. The arrangement position of the composite image sheet 30 for applied stereoscopic images is determined.

  In this position determination method, when the registration unit 35 is observed through the convex lens 12 positioned on the registration unit 35 in a predetermined direction and angle with respect to the convex lens assembly 10, the binocular parallax application stereoscopic image is displayed. The relative position of the convex lens assembly 10 with respect to the composite image sheet 30, that is, the relative position of the convex lens 12 with respect to the unit image 36, in other words, the convex lens assembly with respect to the arrangement direction of the unit images 36 of the binocular parallax applied stereoscopic image composite image sheet 30. Depending on the relative position of the ten convex lenses 12 in the arrangement direction, the registration portion 35 observed through the convex lens 12 looks different. For example, the registration unit 35 shown in FIG. 6 will be described as an example. In all the registration units 35 formed on the top, bottom, left, and right of the binocular parallax application stereoscopic image composite image unit 32, When the relative position of the convex lens assembly 10 with respect to the composite image sheet 30 for images is substantially the same, in other words, the arrangement direction of the unit images 36 of the composite image sheet 30 for binocular parallax applied stereoscopic images and the convex lens assembly 10. When the convex lens 12 is arranged in the vertical direction, the horizontal direction, and the rotational direction substantially coincide with each other, as shown in FIG. 8, the convex lens 12 is located on the registration portion 35 from the front. When the registration unit 35 is observed through the convex lens 12, registration is performed in all the registration units 35 formed on the top, bottom, left, and right of the binocular parallax applied stereoscopic image composite image unit 32. Substantially the entire surface of the convex lens 12 located on the back portion 35, i.e., substantially the entire registration portion 35, the substantially the same as the concentration of the first region 37, appear to become the most highly concentrated. On the other hand, when the relative position of the convex lens assembly 10 with respect to the binocular parallax-applied stereoscopic image composite image sheet 30 does not substantially match, for example, the convex lens 12 positioned on the registration unit 35 from the front of the convex lens 12. Even if the registering part 35 is observed through the convex lens 12, the convex lens 12 positioned on the registering part 35 can be seen only at a low density.

  In this position determination method, the predetermined direction and angle when the registration unit 35 is viewed through the convex lens 12 positioned on the registration unit 35 is a first region 37 in which the first region 37 is allocated in the unit image 36. As shown in FIG. 6, the first area 37 is determined in accordance with the area designation position, and the first area 37 includes a central section in the unit image 36 and a plurality of sections including the central section (hereinafter referred to as a central section or the like). 6), the registration portion 35 may be observed through the convex lens 12 from the front of the convex lens assembly 10, that is, from the perpendicular direction. For example, the first region 37 is shown in FIG. If the unit image 36 is assigned to the upper left section, the registration unit 35 may be observed through the convex lens 12 from the lower right direction with respect to the convex lens assembly 10. , The angle when viewed from this direction, the thickness of the convex lens assembly 10, is appropriately determined by the size of the convex lens 12.

  In the manufacturing method of the first aspect, since the binocular parallax applied stereoscopic image composite image sheet 30 includes the registration unit 35 formed by arranging a plurality of unit images to which the first regions having different densities are allocated, for example, In each of the registration portions 35, the convex lens assembly 10 is relatively moved while observing the registration portion 35 via the convex lens 12, and / or the relative movement and observation of the convex lens assembly 10 are repeated. The binocular parallax-applied stereoscopic image composite image sheet 30 for the convex lens assembly 10 is easily determined by, for example, the position determination method or the like to determine whether or not the one region designated position matches the lens formation section position. Can be accurately and easily determined. In particular, when the first region 37 having a different density is assigned to the central section or the like or the central portion in the unit image 36, the central section or the like or the central portion can be easily visually recognized through the convex lens 12. Therefore, in all the registration units 35, when the arrangement positions of the binocular parallax applied stereoscopic image composite image sheet 30 and the convex lens assembly 10 are substantially coincident with each other, as shown in FIG. Since almost the entire color tone of the first region 37 and the highest density can be seen, the arrangement position of the binocular parallax applied stereoscopic image composite image sheet 30 with respect to the convex lens assembly 10 can be more accurately and easily determined. Can be determined.

  In the manufacturing method of the first aspect, the convex lens assembly 10 and the both are then held in the state where the arrangement position of the composite image sheet 30 for binocular parallax application stereoscopic images with respect to the convex lens assembly 10 determined in this way is maintained. The synthetic image sheet 30 for stereoscopic images applied with an eye parallax is laminated, adhered, or fused. In order to maintain the arrangement position, for example, after determining the arrangement position as described above, a method of fixing a part of the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 together, For example, a method of temporarily fixing the convex lens assembly 10 and the binocular parallax-applied stereoscopic image composite image sheet 30 using fixing means such as a clip, a stapler, and an adhesive tape can be used. In this manner, the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 are laminated while maintaining the arrangement positions of the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30. Alternatively, the other surface 14 of the convex lens assembly 10 and the surface on which the binocular parallax-applied stereoscopic image composite image portion 32 is formed on the binocular parallax-applied stereoscopic image composite image sheet 30 are, for example, an adhesive or an adhesive. Adhering or fusing with adhesive, adhesive tape, etc.

  In the manufacturing method of the first aspect, after the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 are laminated, adhered, or fused, if necessary, the binocular parallax applied stereoscopic image synthesis is performed. The peripheral portion 33 of the image sheet 30 may be excised together with the convex lens assembly 10 on the peripheral portion 33.

  In this way, the binocular parallax applied stereoscopic image sheet structure 1 can be manufactured. That is, the convex lens assembly 10 in which the convex lens 12 focusing on the same plane behind the other surface 14 or the other surface 14 is arranged on one surface 13 of the sheet member 11 is combined with a binocular parallax applied stereoscopic image. An image unit 32 and a registration unit 35 formed around the binocular parallax-applied stereoscopic image composite image unit 32 are provided. The registration unit 35 includes a unit image 36 that can be visually recognized through one convex lens 12. The first region 37 in the unit image 36 is arranged on the composite image sheet 30 for binocular parallax application stereoscopic image in which a plurality of first regions 37 and second regions 38 having different densities are allocated in the unit image 36. Are assigned to the first region, and in the lens formation section 15 where one convex lens 12 is formed, in the lens formation section position corresponding to the first region designation position in the unit image 36. While maintaining the positional relationship substantially matching, it can be stacked and bonded or fused to produce a binocular disparity applications stereoscopic image sheet structure 1. In the manufacturing method of the first aspect, as described above, it is possible to accurately and easily adjust the arrangement position of the binocular parallax applied stereoscopic image composite image sheet 30 with respect to the convex lens assembly 10 by an easy determination method. it can. Therefore, in the binocular parallax applied stereoscopic image sheet structure 1 manufactured in the manufacturing method of the first aspect, the arrangement positions of the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image sheet 30 are accurately adjusted. Therefore, the initial stereoscopic effect is sufficiently exhibited.

  In the example shown in FIG. 6 in the manufacturing method of the first aspect, the first region 37 has a concentration higher than that of the second region 38. In the present invention, the first region is the second region. You may have a density | concentration thinner than a density | concentration. In this case, in the above-described preferable position determination method, when the relative position of the convex lens assembly 10 with respect to the binocular parallax applied stereoscopic image composite image sheet 30 substantially matches, the registration unit from the front of the convex lens 12 When the registering portion 35 is observed through the convex lens 12 positioned on the upper surface 35, almost the entire surface of the convex lens 12 positioned on the registering portion 35, that is, substantially the entire registering portion 35 is in the first region 37. It appears to be the lightest density, almost the same as the density.

  In the example shown in FIG. 6 in the manufacturing method of the first aspect, the registration unit 35 is formed in a part of the peripheral portion 33 surrounding the binocular parallax applied stereoscopic image composite image portion 32. In this invention, the registration part 35 may be formed in the whole peripheral part 33, as FIG. 9 shows.

  Furthermore, in the example shown in FIG. 6 in the manufacturing method of the first aspect, the binocular parallax-applied stereoscopic image composite image sheet 30 has one binocular parallax-applied stereoscopic image composite image section 32. In the present invention, the binocular parallax-applied stereoscopic image composite image unit 32 is not limited to one, and may have a plurality. For example, as shown in FIG. You may have the synthetic image part for parallax application stereo images. In this case, the registration unit 35 includes the peripheral part 33i interposed between the plurality of binocular parallax applied stereoscopic image composite image parts 32 and / or the plurality of binocular parallax applied stereoscopic image composite image parts 32 as a whole. It may be formed in the peripheral portion 33 surrounding the.

  In the manufacturing method of the first aspect, the binocular parallax applied stereoscopic image sheet structure using the convex lens assembly 10 has been described as an example. However, in the present invention, the binocular parallax applied stereoscopic according to the present invention to be described later will be described. As in the third aspect of the manufacturing method of the image sheet structure, the manufacturing method of the first aspect is applied to the binocular parallax application stereoscopic image sheet structure using the convex lens assembly 50 shown in FIG. 17, for example, a lenticular lens. It goes without saying that it can be applied.

  About the manufacturing method of the binocular parallax application stereoscopic image sheet structure of the second aspect in the manufacturing method of the binocular parallax application stereoscopic image sheet structure according to the present invention (hereinafter sometimes referred to as the manufacturing method of the second aspect). This will be described with reference to the drawings. In the manufacturing method of the second aspect, as an example of the binocular parallax application stereoscopic image sheet structure to be manufactured, the other side opposite to the one surface 13 on which the convex lens 12 in the sheet member 11 of the convex lens assembly 10 is arranged. The structure 2 in which the binocular parallax applied stereoscopic image composite image 40 is printed on the surface 14 is shown in FIG. The convex lens assembly 10 in the manufacturing method of the second aspect is as described above.

  In the manufacturing method of the second aspect, the binocular parallax applied stereoscopic image composite image 40 to be printed on the convex lens assembly 10 is created. The binocular parallax applied stereoscopic image composite image 40 is a binocular parallax applied stereoscopic image composite image printed on the sheet member of the binocular parallax applied stereoscopic image composite image sheet 30 prepared in the manufacturing method of the first aspect. Basically the same. Therefore, an example of the binocular parallax-applied stereoscopic image composite image 40 in the manufacturing method according to the second aspect is, as shown in FIG. A peripheral portion 33 surrounding the composite image portion for applied stereoscopic image 32, and four registration portions 35 formed inside the peripheral portion 33 at the top, bottom, left, and right of the composite image portion for binocular parallax applied stereoscopic image, The registration unit 35 includes a plurality of unit images 36 that are visible through one convex lens 12 and is assigned a first region and a second region having different densities. The binocular parallax applied stereoscopic image composite image 40 in the manufacturing method of the second aspect is created in the same manner as in the manufacturing method of the first aspect.

  In the manufacturing method of the second aspect, the printing position of the binocular parallax applied stereoscopic image composite image 40 with respect to the convex lens assembly 10 is then determined. That is, in all the registration parts 35 formed on the top, bottom, left and right of the binocular parallax applied stereoscopic image composite image part 32, the first area designation position to which the first area 37 is assigned in the unit image 36, and this In the lens forming section 15 where one convex lens 12 positioned on the unit image 36 is formed, the lens forming section position defined in the position corresponding to the first region designated position in the unit image 36 is In other words, the printing positions of the convex lens assembly 10 and the binocular parallax-applied stereoscopic image composite image 40 are determined so that the first region designation position and the lens formation section position overlap vertically. . Specifically, the manufacturing method according to the first aspect is basically the same as the contents specifically described with reference to FIGS. 6 and 7.

  In order to determine the printing position, a binocular parallax-applied stereoscopic image composite image 40 including a registration unit 35 and a binocular parallax-applied stereoscopic image composite image part 32 is formed on the other surface 14 of the convex lens assembly 10. Print. After printing the binocular parallax applied stereoscopic image composite image 40 including the registration unit 35 and the binocular parallax applied stereoscopic image composite image portion 32 on the convex lens assembly 10, an appropriate method, for example, the first aspect The printing position is determined by the method exemplified in the manufacturing method.

  In the manufacturing method of the second aspect, the position determination method for determining the printing position where the first region designation position and the position in the lens formation section substantially coincide with each other is the first through the convex lens 12 from the convex lens 12 side. The position determining method for observing one area designated position with a magnifying glass such as a visual or magnifying glass can accurately and easily determine the positional relationship in which the first area designated position and the lens forming section position substantially coincide. It is preferable in that it can be performed. According to this position determination method, in all the registration units 35 formed on the upper, lower, left, and right sides of the binocular parallax applied stereoscopic image composite image unit 32, the registration unit is interposed via the convex lens 12 positioned on the registration unit 35. Binocular parallax with respect to the convex lens assembly 10 so that when the lens 35 is viewed, almost the entire surface of the convex lens 12 positioned on the registration portion 35 appears to be the darkest density almost the same as the density of the first region 37. The printing position of the composite image 40 for applied stereoscopic images is determined.

  In this position determination method, when the registration unit 35 is observed via the convex lens 12 positioned on the registration unit 35 in a predetermined direction and angle with respect to the convex lens assembly 10, the binocular parallax application stereoscopic image composition is performed. Depending on the relative position of the convex lens assembly 10 with respect to the image 40, the registration portion 35 observed through the convex lens 12 looks different. The appearance is the same as the appearance described with reference to FIG. 6 and the like in the manufacturing method of the first aspect. Further, in this position determination method, the predetermined direction and angle when viewing the registration part 35 through the convex lens 12 positioned on the registration part 35 are as described in the manufacturing method of the first aspect.

  The print position of the binocular parallax applied stereoscopic image composite image 40 with respect to the convex lens assembly 10 can be adjusted by, for example, a front / rear / left / right print position adjustment mechanism, a print image inclination adjustment mechanism, or the like in an offset printer. .

  In the manufacturing method of the second aspect, the binocular parallax applied stereoscopic image composite image 40 includes a registration unit 35 that is formed by arranging a plurality of unit images 36 to which the first regions 37 having different densities are allocated. A binocular parallax applied stereoscopic image composite image 40 including a registration unit 35 and a binocular parallax applied stereoscopic image composite image unit 32 is printed on the other surface 14 of the convex lens assembly 10, and all the registration units 35 are printed. In this case, the binocular parallax-applied stereoscopic image composition with respect to the convex lens assembly 10 is performed by an easy determination method, for example, by determining whether the first region designation position matches the position in the lens formation section by the position determination method or the like. The printing position of the image 40 can be determined accurately and easily. In particular, when the first region 37 having a different density is assigned to the central section or the like or the central portion in the unit image 36, the central section or the like or the central portion can be easily visually recognized through the convex lens 12. Therefore, when the printing positions of the binocular parallax-applied stereoscopic image composite image 40 and the convex lens assembly 10 are substantially the same in all the registration units 35, as shown in FIG. Since the entire color tone of the first region 37 and the darkest density are seen, the print position of the binocular parallax applied stereoscopic image composite image 40 with respect to the convex lens assembly 10 is determined more accurately and easily. can do.

  In the manufacturing method of the second aspect, in the state where the printing position of the binocular parallax applied stereoscopic image composite image 40 with respect to the convex lens assembly 10 thus determined is held, the other of the convex lens assembly 10 is maintained. A composite image 40 for binocular parallax applied stereoscopic image is printed on the surface 14.

  In the manufacturing method of the second aspect, after the binocular parallax application stereoscopic image composite image 40 is printed on the other surface 14 of the convex lens assembly 10, the binocular parallax application stereoscopic image composite image 40 is changed as necessary. The peripheral portion 33 may be excised together with the convex lens assembly 10 on the peripheral portion 33.

  In this way, the binocular parallax applied stereoscopic image sheet structure 2 can be manufactured. That is, the binocular parallax is formed on the other surface 14 of the convex lens assembly 10 in which the convex lens 12 focusing on the same plane behind the other surface 14 or the other surface 14 is disposed on one surface 13 of the sheet member 11. A combined image portion 32 for applied stereoscopic images and a registration portion 35 formed on the upper, lower, left and right sides of the binocular parallax applied stereoscopic image combined image portion 32 are provided. The registered portion 35 is visually recognized through one convex lens 12. A binocular parallax-applied stereoscopic image composite image 40 in which a plurality of possible unit images 36 are arranged and a first region 37 and a second region 38 having different densities are allocated in the unit image 36 is displayed in the unit image 36. A lens corresponding to the first region designation position in the unit image 36 in the first region designation position to which one region 37 is assigned and the lens forming section 15 in which one convex lens 12 is formed. In a state in which the formed compartment position holds the substantially print position coinciding, by printing, it is possible to produce a binocular disparity applications stereoscopic image sheet structure 2. In the manufacturing method of the second aspect, as described above, the printing position of the binocular parallax applied stereoscopic image composite image 40 with respect to the convex lens assembly 10 can be accurately and easily adjusted by an easy determination method. . Therefore, in the binocular parallax applied stereoscopic image sheet structure 2 manufactured in the manufacturing method of the second aspect, the positions of the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image 40 are accurately adjusted. The initial stereoscopic effect is sufficiently exhibited.

  In the manufacturing method of the second aspect, similarly to the manufacturing method of the first aspect, the density of the first region 37, the formation position of the registration unit 35, the number of formations of the binocular parallax applied stereoscopic image composite image part 32, and the like. Can be changed as appropriate.

  In the second aspect of the manufacturing method, the binocular parallax applied stereoscopic image sheet structure using the convex lens assembly 10 has been described as an example. However, in the present invention, the binocular parallax applied stereoscopic according to the present invention to be described later will be described. As in the third aspect of the manufacturing method of the image sheet structure, the manufacturing method of the first aspect is applied to the binocular parallax application stereoscopic image sheet structure using the convex lens assembly 50 shown in FIG. 17, for example, a lenticular lens. It goes without saying that it can be applied.

  About the manufacturing method of the binocular parallax application stereoscopic image sheet structure of the third aspect in the manufacturing method of the binocular parallax application stereoscopic image sheet structure according to the present invention (hereinafter sometimes referred to as the manufacturing method of the third aspect). This will be described with reference to the drawings. In the manufacturing method of the third aspect, as an example of the binocular parallax applied stereoscopic image sheet structure to be manufactured, the other side opposite to the one surface 13 on which the convex lens 12 in the sheet member 11 of the convex lens assembly 10 is arranged. The structure 3 in which the binocular parallax applied stereoscopic image composite image 41 is printed on the surface 14 is shown in FIG. The convex lens assembly 10 in the manufacturing method of the third aspect is as described above.

  In the manufacturing method of the third aspect, original images obtained with different parallaxes are prepared. The number of original images is a number that matches the number N of divisions of a unit image that can be viewed through one convex lens 12. As an example of the manufacturing method of the third aspect, the number N of divisions of the unit image that can be visually recognized through the convex lens 12 in the convex lens assembly 10 in which the convex lenses 12 are arranged in the arrangement pattern shown in FIG. Although an example will be described, in the present invention, the arrangement pattern of the convex lenses 12 is not limited to the arrangement pattern shown in FIG. 3, and the number of sections N is as described above and is not limited to 9. Nor.

In this example of the manufacturing method according to the third aspect, nine original images are created with different parallaxes. In this example, as shown in FIG. 13, for example, original images A _{1 to} A representing the state of the subject when the subject is observed with a predetermined interval in the horizontal (lateral) direction and the vertical direction with respect to the subject. ₉ is created. As shown in FIG. 13, the original images A _{1 to} A ₉ are respectively (1, 1), (1, 2), (1, 3), (2, 1) according to the position where the subject is observed. , (2, 2), (2, 3), (3, 1), (3, 2), and (3, 3). These original images are the original images A _{1 to} A ₃ , the original images A _{4 to} A _6, and the original images A _{7 to} A ₉ have a parallax in the horizontal direction, respectively, and the original images A ₁ , A ₄ and A ₇ , The images A ₂ , A ₅ and A ₈ and the original images A ₃ , A ₆ and A ₉ each have a parallax in the vertical direction. The original images A1 to _A9 having different parallaxes can be created by moving the photographing device at a predetermined interval in the horizontal (lateral) direction and the vertical direction with respect to the subject and photographing the subject. Alternatively, it may be created by image editing software or the like.

In the manufacturing method according to the third aspect, of the nine original images A ₁ to 9 prepared in this way, m sheets that match the number m (m <N) of the first area allocated in the unit image. From the original image A, a GCR image a is created by GCR (Gray Color Replacement) while maintaining the color tone.

  Here, in general commercial printing, a technique for expressing a light and shade of a continuous tone image using halftone dots of inks such as cyan ink, magenta ink, yellow ink, and black ink is applied. For example, normally, in monochrome images and color images, the area ratios of cyan ink, magenta ink, yellow ink, and black ink are appropriately changed, and images are formed by adjusting to desired colors and hues. In this technology, black ink is added to supplement the color plates of cyan ink, magenta ink and yellow ink, but in addition, as a gray alternative ink expressed by halftone dots with cyan ink, magenta ink and yellow ink. Can also be used. Therefore, even if the area ratio of cyan ink, magenta ink, yellow ink and black ink, that is, the density of these inks is different, the same hue can be expressed. For example, a color consisting of halftone dots with an area ratio of about 50%, about 100%, about 100% and about 10% for cyan ink, magenta ink, yellow ink and black ink, and about 30% and about 95%, respectively. , About 95% and about 30% of the color consisting of halftone dots are recognized by the naked eye as substantially the same hue, specifically brown, under visible light. In the present invention, GCR refers to replacing not only the shadow portion of an image but also the gray component up to the highlight in the image with black ink, and the image created in this way is referred to as GCR image a. More simply, GCR is UCR (Under Color Removal), which is a method of replacing gray and K (black or black) components where CMY signals overlap in all areas from the highlight area to the shadow area. Yes, full black, achromatic plate making.

In the manufacturing method of the third aspect, focusing on the GCR, the binoculars with respect to the convex lens assembly 10 using the registration part to which regions having different densities are assigned and the convex lens 12 positioned above the registration part are used. The printing position of the composite image 41 for parallax applied stereoscopic images is determined. As an example of a registration unit density different areas are assigned, in FIG. 14, the unit image R ₁₁ are partitioned divided into 9 sections, the first region 1 partitioning (P ₁₁₂₂₎ of 9 compartments partitioned split An example assigned to is shown. According to this example, only one original image A ₅ rearranged in the section P ₁₁₂₂ assigned to the first area is subjected to GCR processing. The designation R _(XYab) of each section formed by dividing the unit image R is the position R _(XY) on the XY coordinates of the unit image R in the original image A and GCR image a in which the unit image R is included, and this unit. appears from the position on the xy coordinate _{R (XYab)} in the image _{R (XY)} within shows as an example, each compartment and its designated in compartment _{R 11} or the like located at the top left of the image (name) in FIG. 14 It is.

In the manufacturing method of the third aspect, in determining the printing position in the manner described above, first, the original image A _5, without changing the color tone of the original image A _5, the GCR, cyan ink, magenta ink Then, a new GCR image a ₅ (not shown) is created by changing the ink area ratio at each dot of yellow ink and / or black ink, that is, the density of the ink. Such a GCR image can be created by using image processing software such as “Adobe Photoshop”, for example. In the manufacturing method according to the third aspect, the ink area ratio of black ink is mainly changed by GCR, and the ink area of cyan ink, magenta ink and / or yellow ink is auxiliary changed along with this change. This is preferable in that the determination method described later becomes easy.

In the manufacturing method of the third aspect, a binocular parallax applied stereoscopic image is then obtained using the GCR image a ₅ thus created and the eight original images A _{1 to} A ₄ and A _{6 to} A _9. The binocular parallax applied stereoscopic image composite image 41 is created in accordance with the above-described synthesis method, for example, the integral photography image synthesis method.

The method for synthesizing the integral photography image is well known, but will be briefly described below. One method for synthesizing an integral photography image is N compressions obtained by compressing each of the divided pixels from N original images created with different parallaxes to a size of 1 / N. In this method, one new unit image in which the sections are rearranged is created, and this operation is repeated to form one composite image. The synthesis of this integral photography image, by taking a unit image R ₁₁ as an example will be described more specifically. First, sections R _{11A1 to} R _11A4 , R _{11A6 to} R _11A9, and GCR section R _{11a5 in} which the unit images R _{11 of} the original images A _{1 to} A ₄ and A _{6 to} A ₉ and the GCR image a ₅ are divided into pixels are _defined . The nine compressed sections R ′ _{11A1 to} R ′ _11A4 , R _′ 11A6 to R ′ _11A9 and the compressed GCR section R ′ _11a5 obtained by compressing each of them to 1/9 are photographed in the XY coordinates in the original image. One new unit image rearranged so as to be symmetric (-Y, -X) with the position (XY) is created. In this method, the composite image 41 is formed by repeating this operation.

One of the methods for synthesizing the integral photography image is to delete segment data other than a desired region from among the respective segments obtained by pixel division from N original images created with different parallaxes. This is a method in which a single unit image is created by sequentially stacking the stacking sections, and this operation is repeated to form one composite image. The synthesis of this integral photography image, by taking a unit image R ₁₁ as an example will be described more specifically. First, the original image _A 1 of the to A ₄ and _A 6 to A ₉ and GCR compartment _R each unit image _{R 11} and image _{a 5} is divided into pixels 11A1 ~R _{11A4, R 11A6} ~R _11A9 and GCR compartment _{R 11a5} Of these, partition data obtained by erasing partition data other than regions (each region indicated by r in FIG. 13) that are symmetrical (-Y, -X) with the XY coordinate shooting position (XY) in the original image of each partition. Nine stacking sections having only a single layer are sequentially stacked to create a new unit image having nine section data, the whole of which is derived from the original image. In this method, the composite image 41 is formed by repeating this operation.

In the production method of the third aspect, in forming a single composite image 41 in this manner, GCR compartment _{R 11a5} of unit image _{R 11} of the GCR image _{a 5} is divided into pixels, the binocular disparity is synthesized first area assigned to applied stereo-image in the unit image _{R 11} in the composite image 41, in this example, as shown in FIGS. 14 and 15, the partition _{P 1122} which is defined in the unit image _{R 11,} The binocular parallax to which the sections R _{11A1 to} R _11A4 and R _{11A6 to} R _{11A9 that} are _rearranged and the pixel images of the unit images R _{11 of} the original images A _{1 to} A ₄ and A _{6 to} A ₉ are divided are combined. a second region allocated within the unit image R ₁₁ in applications stereoscopic image combined image 41, in this example, 14, and as shown in FIG. 15, partition P ₁₁ which is defined in the unit image R _{11 33 to} P ₁₁₁₃ , P ₁₁₃₂ , P ₁₁₁₂ and P _{1131 to} P ₁₁₁₁ are rearranged in order.

In this way, for each unit image R, rearrangement of the pixel-divided sections or GCR sections is executed by the integral photography image combining method, and the first regions having different densities (for example, GCR section R _11a5 ). Then, a binocular parallax applied stereoscopic image composite image 41 having a registration unit in which a plurality of unit images R to which the second region is assigned is arranged is created. The method for synthesizing the integral photography image can be executed by applying image software or the like. The binocular parallax applied stereoscopic image composite image 41 includes a plurality of unit images R each having a first area and a second area.

In the manufacturing method of the third aspect, the printing position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 is then determined. That is, a single-color image of the binocular parallax applied stereoscopic image composite image 41 made of one kind of the ink is printed on the other surface 14 of the convex lens assembly 10, and a first region (for example, P ₁₁₂₂ ) is included in the unit image. In the lens formation section 15 in which the assigned first area designation position and one convex lens 12 located on the unit image are formed, the image is defined at a position corresponding to the first area designation position in the unit image. The print position of the binocular parallax applied stereoscopic image composite image 41 is determined so that the position in the formed lens formation section substantially coincides. More specifically, referring to FIGS. 6 and 7, the first region designation position is assigned with the first region 37 in each unit image R corresponding to each unit image 36 as shown in FIG. 6. The position, that is, the position occupied by the central section 37 in each unit image 36, for example, P ₁₁₂₂ . On the other hand, as shown in FIG. 7, the lens forming section position defines the lens forming section 15 in which the convex lenses 12 arranged in the convex lens assembly 10 are formed in the same manner as the unit image 36, that is, the vertical and horizontal directions. Assuming that a total of nine sections are defined, the position (virtual section) corresponding to the position (section) in the unit image to which the first area designation position is assigned in the defined lens forming section 15. ), That is, the position occupied by the central virtual section 16 in each lens forming section 15. Then, the convex lens assembly 10 is arranged so that the first region designation position and the lens formation section position substantially coincide with each other, in other words, the first region designation position and the lens formation section position overlap. The printing relationship with the binocular parallax applied stereoscopic image composite image 41 is determined.

  In order to determine the printing position, first, a monochromatic image of the binocular parallax applied stereoscopic image composite image 41 made of a kind of ink, preferably black ink, is printed on the other surface 14 of the convex lens assembly 10. After the monochromatic image of the binocular parallax applied stereoscopic image composite image 41 is printed on the convex lens assembly 10, the printing position is determined by an appropriate method. In the manufacturing method of the third aspect, each unit image R in the monochromatic image printed on the convex lens assembly 10 has a different density of one kind of ink in the first area from the density of the same ink in the second area. The first region serves as a mark for adjusting the printing position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10. Therefore, after printing a monochromatic image on the convex lens assembly 10, an appropriate method, for example, through the monochromatic image and the convex lens assembly 10 from the back of the monochromatic image, using a discrimination assisting means such as infrared irradiation if desired, A method of observing the first region designated position and the lens formation section position with a magnifying glass such as a magnifying glass or the like, or the first region designated position from the convex lens 12 side via the convex lens 12 by visual observation or a magnifying glass The printing position can be determined by a method of observing with a magnifying glass or the like.

  In the manufacturing method of the third aspect, the position determination method for determining the positional relationship in which the first region designation position and the position in the lens formation section substantially coincide with each other is the first through the convex lens 12 from the convex lens 12 side. The position determination method for observing one region designated position with a magnifying glass such as a visual or loupe is a positional relationship in which the first region designated position and the lens forming section position substantially coincide with each other, that is, both with respect to the convex lens assembly 10. This is preferable in that the printing position of the composite image 41 for the eye parallax applied stereoscopic image can be accurately and easily determined. According to this position determination method, when the monochromatic image is viewed through the convex lens 12 positioned on each unit image of the monochromatic image, almost the entire surface of the convex lens 12 positioned on the monochromatic image is substantially equal to the density of the first region. The print position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 is determined so that the darkest density appears to be the same.

  In this position determination method, when a monochromatic image is observed through the convex lens 12 positioned on the monochromatic image at a predetermined direction and angle with respect to the convex lens aggregate 10, a convex lens for the binocular parallax applied stereoscopic image composite image 41 is obtained. Relative position of the aggregate 10, that is, the relative position of the convex lens 12 with respect to the unit image R, in other words, the arrangement direction of the convex lens 12 of the convex lens aggregate 10 with respect to the arrangement direction of the unit image R of the binocular parallax applied stereoscopic image composite image 41 Depending on the relative position, the monochromatic image observed through the convex lens 12, in particular, its density appears different. For example, when the relative position of the convex lens assembly 10 with respect to the binocular parallax applied stereoscopic image composite image 41 is substantially the same, in other words, the arrangement direction of the unit images R of the binocular parallax applied stereoscopic image composite image 41 And the arrangement direction of the convex lenses 12 of the convex lens assembly 10 are substantially the same in the vertical direction, the horizontal direction, and the rotational direction, through the convex lens 12 positioned on the monochromatic image from the front of the convex lens 12. When observing the monochromatic image, almost the entire surface of the convex lens 12 positioned on the monochromatic image, that is, almost the entire monochromatic image, appears to have the darkest density almost the same as the density of the first region. On the other hand, when the relative position of the convex lens assembly 10 with respect to the binocular parallax-applied stereoscopic image composite image 41 does not substantially match, a monochrome image can be seen at a density different from that of the first region of the monochrome image.

  In this position determination method, the predetermined direction and angle when a monochromatic image is viewed through the convex lens 12 positioned on the monochromatic image depends on the first area designated position where the first area is allocated in the unit image R. As shown in FIG. 6, when the first region is assigned to the central section in the unit image R, the front surface of the convex lens assembly 10, that is, the monochromatic color through the convex lens 12 from the perpendicular direction. For example, when the first region 37 is assigned to the upper left section of the unit image 36 shown in FIG. 6, the convex lens 12 is moved from the lower right direction to the convex lens assembly 10. The angle when viewing from this direction is appropriately determined depending on the thickness of the convex lens assembly 10, the size of the convex lens 12, and the like.

  The print position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 can be adjusted by, for example, a front / rear / left / right print position adjustment mechanism, a print image inclination adjustment mechanism, or the like in an offset printing machine. .

  In the manufacturing method of the third aspect, since the GCR sections obtained by pixel-dividing from the GCR image are rearranged in the first region allocated in each unit image R of the binocular parallax applied stereoscopic image composite image 41, a convex lens A monochromatic image of the binocular parallax-applied stereoscopic image composite image 41 is printed on the other surface 14 of the aggregate 10, and whether or not the first region designation position where the GCR sections are rearranged and the lens forming section position match. With this easy determination method, it is possible to accurately and easily determine the print position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10. In particular, when the first region in which the GCR sections are rearranged is assigned to the central section or the like or the central portion in each unit image, the central section or the like or the central portion is easily visually recognized through the convex lens 12. Therefore, when the print positions of the binocular parallax-applied stereoscopic image 41 and the convex lens assembly 10 are substantially coincident with each other, almost the entire convex lens 12 has the color tone of the first region and the darkest color. Since the density becomes visible, the print position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 can be determined more accurately and easily.

  In the manufacturing method of the third aspect, the other position in the convex lens assembly 10 is then maintained in a state where the print position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 determined in this way is maintained. A composite image 41 for binocular parallax applied stereoscopic image is printed on the surface 14.

  In this way, the binocular parallax applied stereoscopic image sheet structure 3 can be manufactured. In the manufacturing method of the third aspect, as described above, the printing position of the binocular parallax applied stereoscopic image composite image 41 with respect to the convex lens assembly 10 can be accurately and easily adjusted by an easy determination method. . Therefore, in the binocular parallax applied stereoscopic image sheet structure 3 manufactured in the manufacturing method of the third aspect, the positions of the convex lens assembly 10 and the binocular parallax applied stereoscopic image composite image 41 are accurately adjusted. The initial stereoscopic effect is surely exhibited.

As another example of the manufacturing method of the third aspect, an example using the convex lens assembly 50 will be described. In the example using the convex lens assembly 50, the binocular parallax application stereoscopic image sheet structure can be manufactured basically in the same manner as in the example of the manufacturing method of the third aspect. An image composite image 61 is created so as to correspond to the convex lens assembly 50. That is, the unit images in the convex lens assembly 50 are obtained in a state having N different parallaxes in the horizontal direction, respectively, corresponding to the number N of divisions (N = 5 in the example shown in FIG. 18). Original images B _{1 to} B ₅ are prepared. Then leave, (in the example shown in FIG. 18, m = 1) a first region number of partitions of m to be assigned to the unit image R a m Like the original image B ₃ of matching, maintaining the color tone, GCR Thus, a GCR image b ₃ is created by changing the ink area ratio of cyan ink, magenta ink, yellow ink and / or black ink. Next, using the G GCR images b ₃ and the (N−m) original images B ₁ , B ₂ , B ₄ and B ₅ , m GCR sections obtained by pixel division from the GCR image b ₃ are obtained. In the first region (in the example shown in FIG. 18, a region located at the center of the region divided into five) according to the binocular parallax applied stereoscopic image synthesis method, that is, in the horizontal direction of the original images B _{1 to} B ₅ A composite image 61 for binocular parallax application stereoscopic image having a registration unit rearranged so as to be in an arrangement order opposite to the arrangement order is created. Printing the binocular parallax applied stereoscopic image composite image 61 using the binocular parallax applied stereoscopic image composite image 61 thus created basically in the same manner as in the example of the manufacturing method of the third aspect. The position is determined, and the binocular parallax applied stereoscopic image composite image 61 is printed on the other surface 54 of the convex lens assembly 50 in a state where the print position is held.

  Thus, the binocular parallax applied stereoscopic image sheet structure in another example of the manufacturing method of the third aspect can be manufactured. In another example of the manufacturing method of the third aspect, as described above, the print position of the binocular parallax applied stereoscopic image composite image 61 with respect to the convex lens assembly 50 is accurately and easily adjusted by an easy determination method. can do. Therefore, in the binocular parallax applied stereoscopic image sheet structure manufactured in another example of the manufacturing method of the third aspect, the positions of the convex lens assembly 50 and the binocular parallax applied stereoscopic image composite image 61 are accurately adjusted. Therefore, the initial stereoscopic effect is surely exhibited.

  According to the manufacturing method of the third aspect, unlike the manufacturing method of the first aspect and the manufacturing method of the second aspect, the binocular parallax applied stereoscopic image composite image 41 is printed on the other surface 14 of the convex lens assembly 10. Since an unnecessary part does not occur later, it is not necessary to excise this part, so that the manufacturing efficiency can be improved and the manufacturing cost can be reduced.

It has a binocular parallax applied stereoscopic image composite image 41 having a plurality of registration portions arranged inside.

Therefore, the binocular parallax application stereoscopic image sheet structure according to the present invention is the third region according to the present invention. There is also an advantage that it is possible to easily determine whether or not the sheet structure is manufactured in the manufacturing method of the aspect.

  In the above example in the manufacturing method of the third aspect, the GCR sections are rearranged in one first region, but in this invention, the GCR sections may be rearranged in a plurality of first regions.
