Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image panel in which a changing image and a dynamic image can be viewed stereoscopically without using a conventional lenticular lens. More specifically, the present invention relates to a stereoscopically visible image panel formed by forming a striped masking by printing or the like instead of a lenticular lens, and a method for manufacturing the panel.
[0002]
[Prior art]
Conventionally, as a highly accurate image forming means in a stereoscopic image panel, a stereoscopic image printing method disclosed in Japanese Patent Laid-Open No. 55-130794 has been put into practical use, and registered utility model No. 3012146 discloses two methods. There has been disclosed a lenticular printed matter in which a three-dimensional image, a dynamic image, or a plurality of double image screens can be alternately viewed by combining a multiple image screen and a lenticular screen in a freely detachable manner.
[0003]
In the former three-dimensional image printing method disclosed in Japanese Patent Laid-Open No. 55-130794, as shown in FIG. 15, a single lenticular plate 7 in which a plurality of cylindrical lenses (kamaboko-shaped lenses) are arranged in parallel is arranged on one back surface. Image information L and R (L (L) viewed from different directions (viewpoints 8 and 9) ₁ , R ₁ ... L _i , R _i , I is a positive integer) are alternately arranged to form a plurality of thin stripes. By viewing the image information L and R from the viewpoints 8 and 9 via the lenticular plate 7, It is made to be visible as a stereoscopic image.
[0004]
Further, the lenticular printed matter disclosed in the latter registered utility model No. 3012146 divides two images into a plurality of linear bands each having a predetermined width, and these linear bands are alternately arranged with different images. A print screen or lenticular, which is a combination of lenticular screens that are arranged in a single screen so that they are adjacent to each other, and are formed with many kamaboko-shaped lenses with the same width as the linear band of this print screen. By swinging one of the screens, the design of the print screen can be seen as a stereoscopic image or a dynamic image.
[0005]
In the prior art, by using a lenticular plate or a lenticular screen (hereinafter collectively referred to as “lenticular plate”) in which a large number of kamaboko lenses are formed in parallel, a combined image arranged on the back surface thereof Is viewed as a stereoscopic image.
[0006]
[Problems to be solved by the invention]
The lenticular plate in which a number of the conventional kamaboko lenses are formed in parallel is usually manufactured by molding a transparent synthetic resin with a mold.
[0007]
However, when resin molding with a mold, expensive mold costs (several million yen) are required, and also when printing images on the back of the lenticular plate, corresponding to the pitch of the kamaboko lens after formation, In parallel with this, an image with a linear band must be printed accurately, and this alignment is particularly troublesome because it requires accuracy, and the required printing accuracy cannot be obtained easily. .
[0008]
The present invention has been made in view of such problems, and can be produced by a normal printing technique or the like without requiring a lenticular lens, and a changing image and a dynamic image can be visually recognized in three dimensions. It is an object to provide a three-dimensional image panel, a method for manufacturing the panel, and a method for manufacturing the panel.
[0009]
[Means for Solving the Problems]
Therefore, as a result of various studies to improve the lenticular plate in which many of the kamaboko-shaped lenses are formed in parallel, the present inventor has repeatedly studied the above problems as a person engaged in printing, and as a result, the main function of the lenticular plate is not the lens effect. It was found that a visible part and an invisible part are formed with respect to a symbol positioned below the lenticular plate. That is, for example, according to FIG. _R From the left eye 9, the lens curved surface B can be seen. _L It is impossible to see the image of the part that becomes the shadow side of.
[0010]
And as a result of repeating various studies based on the knowledge, instead of the conventional lenticular plate, on the surface of the transparent substrate of a predetermined thickness, the pattern of the linear band positioned below the transparent substrate and the same pitch By forming masking with stripes (vertical stripes), the masking acts in the same way as the action of hiding the image of the shadow side part in the case of the lenticular plate, so that the lenticular plate through the kamaboko lens shape is used. Thus, the present invention has been completed, in which a stereoscopic image similar to that seen can be seen.
[0011]
That is, the stereoscopically-viewable image panel according to the first aspect of the present invention looks at the design 2 to which a stereoscopic effect is imparted by three-dimensional image processing from a different viewpoint. Two parallax patterns obtained respectively Is divided into a plurality of linear bands of equal width, and the arrangement pattern S is formed as a single pattern by arranging the linear bands obtained from the parallax patterns so as to be alternately adjacent to each other while maintaining the division order. A plurality of masking 3 provided on the back surface of the transparent substrate 1 having a predetermined thickness and having the same width as the two linear bands on the front surface of the transparent substrate 1 are spaced apart by the same width as the masking 3. In this state, the masking 3 is provided in stripes so that each position of the masking 3 corresponds to each position of the linear band.
With such a configuration, an image panel that can visually recognize a three-dimensional design as a three-dimensional image without using a lenticular lens is obtained.
[0012]
The equal width may be any width that can be equally divided within the range of variations during actual manufacturing, but the thinner the width, the better the visual effect. In addition, the number of linear bands may be an even number or an odd number as long as they are equally divided.
[0013]
The meaning that the linear bands are alternately arranged adjacent to each other while maintaining the order of division to form a single symbol means that the linear bands are connected without gaps and without overlapping. In addition, the meaning that each position of the masking corresponds to each position of the linear band means that the boundary position between the linear bands and the masking position correspond to each other as seen from above as shown in FIG. That means These term expressions have the same meaning in the description of other embodiments below.
[0014]
The image panel according to the second aspect of the present invention has a three-dimensional image processing, and the two types of symbols provided with a three-dimensional image are viewed from different viewpoints. A total of four parallax patterns obtained. Is divided into a plurality of linear bands of equal width, and the arrangement pattern S is formed as a single pattern by arranging the linear bands obtained from the parallax patterns so as to be alternately adjacent to each other while maintaining the division order. A plurality of masking 3 provided on the back surface of the transparent substrate 1 having a predetermined thickness and having the same width as the two linear bands on the front surface of the transparent substrate 1 are spaced apart by the same width as the masking 3. In this state, the masking 3 is provided in stripes so that each position of the masking 3 corresponds to each position of the linear band, and different images can be seen three-dimensionally by changing the viewpoint. It is characterized by.
With such a configuration, an image panel can be obtained in which different images can be visually recognized as a three-dimensional image by changing the viewpoint of the two types of symbols imparted with a three-dimensional effect without using a lenticular lens.
[0015]
The three-dimensional image panel according to the third aspect of the present invention has a perspective that gives perspective to a plurality of different designs by three-dimensional image processing, or a composite design that gives a stereoscopic effect with perspective. The two parallax symbols obtained from each view are divided into a plurality of linear bands with the same width, and the linear bands obtained from the parallax symbols are arranged so as to be adjacent to each other while maintaining the division order. Then, an array design S as a single design is formed by printing on the surface of the first transparent film 1a, and the masking 3 having the same width as the two linear strips is the same as the width of the masking 3 A plurality of stripes are arranged on the back surface of the second transparent film 1b in a striped manner, and the surface of the transparent film 1a is bonded to the back surface of the transparent substrate 1 having a predetermined thickness. And the mass The back surface of the second film 1b is bonded to the surface of the transparent substrate 1 so that each of the ring 3 corresponds to each position of the linear band of the array pattern S, and an image having a sense of perspective is obtained. It is characterized by three-dimensional appearance.
With this configuration, an image panel can be obtained in which a design with a sense of perspective can be visually recognized as a stereoscopic image without using a lenticular lens.
[0016]
The image panel according to the fourth aspect of the present invention has a three-dimensional image processing on each surface of a plurality of different forms of dynamic symbols on one surface of a transparent substrate 1 having a predetermined thickness. While giving a three-dimensional feeling Left and right Obtained from different perspectives Number of parallax symbols twice as many as the number of dynamic symbols Is divided into a plurality of linear bands each having an equal width, and an array pattern S is obtained by arranging the linear bands obtained from the parallax patterns in such a manner that they are alternately adjacent to each other while maintaining the division order. The masking 3 having the width of the number of linear bands obtained by multiplying the number of different viewpoints by one less than the number of the dynamic symbols is provided on one surface of the image substrate A and the transparent film 1c. A stripe film B provided in a stripe shape so as to correspond to each position of the linear band in a state of being arranged with the same width as the width of the same number of different viewpoints with respect to the dynamic pattern. The image substrate A and the stripe film B are relatively movable in contact with each other in a direction orthogonal to the direction of the stripe, and a plurality of different forms of dynamic images are formed by the movement of the stripe film. Looks three-dimensional It is characterized in.
With this configuration, an image panel can be obtained in which a plurality of different forms of dynamic images can be viewed as a three-dimensional image without using a lenticular lens by moving the stripe film.
[0017]
The configuration of the stereoscopically visible image panel according to the present invention will be described in more detail as follows. In this specification, to give a three-dimensional effect is to make an image appear shaded, hide a hidden surface (shading process), and calculate the intensity of light and color it to make it appear three-dimensional. In other words, giving a sense of perspective means that two objects appear to have a relative front-rear positional relationship with a sense of depth by a perspective method.
[0018]
First, as the transparent substrate 1 in the present invention, a polyester plate, a polycarbonate plate, a polyvinyl chloride plate, a glass plate, etc. can be used in addition to a commercially available synthetic resin acrylic plate, and the thickness is about 0.3 to 10 mm. From the viewpoint of obtaining a more natural stereoscopic effect or perspective visual effect, it is preferably about 2 to 5 mm.
[0019]
In addition, the printed pattern provided by the method of assembling the linear bands provided on the back side of the transparent substrate 1 can be provided by the stereoscopic image printing method disclosed in the above-mentioned JP-A-55-130794. At present, it can be formed using a personal computer or the like using commercially available program software (for example, three-dimensional software: referred to as “3D software”).
[0020]
That is, according to such program software, three-dimensional image processing is performed on the original drawing (symbol) of a photograph or design image to give a three-dimensional effect or perspective (depth) to the symbol on the computer, From different perspectives Two symbols obtained (Hereinafter referred to as parallax symbols) are divided into equal widths to form linear bands of different parallax patterns, and a plurality of linear bands obtained from the different parallax patterns are alternately adjacent to maintain the division order. Can be easily combined. Here, the viewpoint for obtaining the parallax pattern is often set at a plurality of points on substantially the same plane, but may be points at different distances before and after.
[0021]
For the work of giving a three-dimensional effect or perspective (depth) to the pattern (original drawing) by the three-dimensional image processing, for example, using “shade” (software manufactured by Ex Tools Co., Ltd.) For example, using "Photoshop" (software manufactured by Adobe Systems) Each image processing for the symbol can be easily and reliably performed by a computer.
[0022]
As described above, the parallax symbols obtained by dividing the parallax symbols obtained from different viewpoints on the left and right sides are alternately adjacent to each other with different parallax symbols obtained by dividing the parallax symbols. Arranged symbols in the form of being arranged while being combined can be visually recognized as a stereoscopic image by binocular viewing through a plurality of slits provided corresponding to the width of the linear band with a certain dimension. The image panel according to the present invention can provide a three-dimensional visual effect even when viewed with one eye.
[0023]
In addition, the procedure for providing the pattern (array pattern) S obtained by arranging a plurality of linear bands on the back surface of the transparent substrate 1 is not only direct printing such as silk printing but also printing on another transparent film as an adhesive. However, direct printing is easy, reliable, and inexpensive.
[0024]
At this time, the width of the pattern printed as a linear band on the back surface of the transparent substrate 1 can be arbitrarily set by an actual printing apparatus or the like, but in the case of offset printing, an extremely thin linear pattern of about 0.08 mm. Even in the case of screen printing, a thin linear pattern of about 0.16 mm is obtained.
[0025]
Therefore, the width of the linear band is not particularly limited and can be set freely. The thinner the band, the denser the stereoscopic image.
[0026]
Next, combinations of symbols provided on the back side of the transparent substrate 1 will be described (see FIGS. 1 to 3). As a design to be provided on the back side, one design may appear three-dimensionally, several different designs may appear three-dimensional, and several different designs may You may combine as a three-dimensional design or a three-dimensional design with a different perspective.
[0027]
In addition, the arrangement pattern S and the striped masking 3 are provided on the front surface side and the back surface side of the single transparent substrate 1, respectively, so that a stereoscopic image can be viewed, and the pattern ( It was obtained from different perspectives for the design with three-dimensionality and perspective added to the (original drawing) and multiple different forms of dynamic designs. Number of parallax symbols twice as many as the number of dynamic symbols Is divided into a plurality of linear bands each having a predetermined width, and each linear band obtained from the parallax pattern is alternately adjacent to each other and arranged in a divided order to form a single pattern. The arrangement pattern is provided on the single transparent substrate 1 by direct printing or pasting, while the striped masking 3 is provided on another transparent film so that both are kept in contact with each other or have a small gap. Thus, it can be configured to be in a butt contact state and relatively movable in a direction orthogonal to the direction of the stripe. If comprised in this way, by changing this transparent film to right and left, the changing of two or more images and a dynamic image will be seen in three dimensions from the same position.
[0028]
next, other A three-dimensional image panel can be set to a plurality of stripe widths WS in the screen, and the masking width can be set to correspond to the stripes. You can change it, or you can differentiate between showing more and showing less.
[0029]
next, other The three-dimensional image panel is obtained by dividing the first and second parallax symbols obtained by viewing the symbol 2 given the three-dimensional effect by the three-dimensional image processing from different viewpoints into tiles in the same square. Ah, Bhk (where hkmn is a positive integer, hk is an odd number, 1 ≦ h ≦ m, 1 ≦ k ≦ n). The tile Bhk is arranged on the right side of the tile Ahk for the same subscript, and Ahk and Bhk keep the original symbol matrix arrangement alternately with each other regularly or under the tile Ahk for the same subscript. Ahk and Bhk are arranged in an array design S in which the tiles are regularly arranged alternately while keeping the matrix arrangement of the original design, and the design S is arranged as a single design. Provided on the back surface of the transparent substrate 1 having a predetermined thickness The masking having a size of 2 rows and 2 columns is arranged on the surface of the transparent substrate 1 corresponding to each tile position of the array pattern for each checkered position of the checkerboard pattern. .
[0030]
Here, the tile division means that the plane is equally divided so as to obtain a form in which the tiles are bonded so as to spread the plane with tiles having substantially the same square shape. In the alternate arrangement of the tiles, the upper, lower, left, and right are defined because the subscript 11 is in the upper left position in the matrix display by subscript. That is, as shown in FIG. 6, the subscripts 12 and 13 are arranged in the right order, and the subscripts 21 and 31 are arranged in the lower order. In this way, tile A _hk Tile B to the right of _hk Tile A _hk Tile B underneath _hk Is expressed.
[0031]
Therefore, tile A _hk Tile B to the right of _hk For the first row is A ₁₁ , B ₁₁ , A _{twenty one} , B _{twenty one} , A ₃₁ , B ₃₁ A ... _h1 , B _h1 A ... _m1 , B _m1 , Second column B ₁₂ , A ₁₂ , B _{twenty two} , A _{twenty two} , B ₃₂ , A ₃₂ , ..., B _h1 , A _h1 , ..., B _m2 , A _m2 , …………, column k is A _1k , B _1k , A _2k , B _2k , A _3k , B _3k ・ ・ ・ …… A _hk , B _hk A ... _mk , B _mk , Column k + 1 is B _{1, k + 1} , A _{1, k + 1} , B _{2, k + 1} , A _{2, k + 1} , B _{3, k + 1} , A _{3, k + 1} , ..., B _h1 , A _h1 , ..., B _{m, k + 1} , A _{m, k + 1} It is configured like this.
[0032]
Similarly, tile A _hk Tile B underneath _hk The first left column is A ₁₁ , B _{twenty one} , A ₃₁ , B ₄₁ A ... _h1 , B _{h + 1,1} A ... _m1 , B in the first right column ₁₁ , A _{twenty one} , B ₃₁ , A ₄₁ , ..., B _h1 , A _{h + 1,1} , ..., B _m1 …………, the kth left column is A _1k , B _2k , A _3k , B _4k ・ ・ ・ …… A _hk , B _{h + 1, k} A ... _mk , The kth right column is B _1k , A _2k , B _3k , A _4k , ..., B _hk , A _{h + 1, k} , ..., B _mk , The (k + 1) th left column is A _{1, k + 1} , B _{2, k + 1} , A _{3, k + 1} , B _{4, k + 1} ・ ・ ・ …… A _{h, k + 1} , B _{h + 1, k + 1} A ... _{m, k + 1} , The (k + 1) th right column is B _{1, k + 1} , A _{2, k + 1} , B _{3, k + 1} , A _{4, k + 1} , ..., B _{h, k + 1} , A _{h + 1, k + 1} , ..., B _{m, k + 1} It is configured like this.
[0033]
The meaning of dividing the first and second parallax symbols into tiles is that the first and second parallax symbols are squares or rectangles having the same shape. This means that the tiles are divided without producing a half-end portion in which the size of the tile is half-end. Therefore, if the first and second parallax symbols are rectangular, it is preferable that the common divisor of the long side and the short side is the side length of the tile.
The number of divided rows or columns may be an odd number or an even number.
[0034]
As for the notation of the matrix arrangement of tiles, A is displayed as first and B as second in order to show the regularity of the arrangement in which A and B are regularly alternated. Is).
[0035]
In addition, the subscripts h and k are described assuming that they are odd numbers for the sake of explanation of the regularity. However, the subscripts h and k are not requirements. If they are even numbers, A and B in h rows or k columns are odd numbers. It can be expressed in reverse terms.
[0036]
For example, tile A _hk Tile B underneath _hk If k is an even number, the k-th column is B _1k , A _1k , B _2k , A _2k , B _3k , A _3k , ..., B _hk , A _hk , ..., B _mk , A _mk , K + 1 column is A _{1, k + 1} , B _{1, k + 1} , A _{2, k + 1} , B _{2, k + 1} , A _{3, k + 1} , B _{3, k + 1} A ... _h1 , B _h1 ・ ・ ・ …… A _{m, k + 1} , B _{m, k + 1} It is.
[0037]
In addition, each tile is regularly and alternately arranged to form one pattern, which means that all tiles are connected to each other without gaps and without overlapping so as to form a single pattern.
[0038]
The masking arrangement can be expressed, for example, as a checkered pattern of alternating black and white patterns. That is, the checkered pattern misplacement position means, for example, the arrangement position of only one of the checkerboard patterns when only black or white is considered, or only black if it is black. .
[0039]
Such an arrangement can also be said to be a parallel zigzag arrangement (or zigzag arrangement, zigzag arrangement) of black tiles. Moreover, the checkerboard pattern may be referred to as a checkerboard pattern.
[0040]
In the present invention, since A and B can be exchanged, when attention is paid to any one of the tiles, it may be either white or black. The single 4 adjacent tile is of course the opposite color.
[0041]
The size of the masking is for 2 rows and 2 columns of tiles, and the arrangement positions thereof correspond to the arrangement positions of the tiles of the array symbol as shown in FIG. However, as shown in FIG. 11, a masking Mx having a size corresponding to one row and two columns or two rows and one column may be provided in the endmost row or endmost column.
[0042]
With this configuration, the array pattern can be obtained as a stereoscopic effect by shifting the line of sight to the image panel in the left-right direction, and can also be obtained as a stereoscopic image by shifting the line of sight in the vertical direction A visible image panel is obtained.
[0043]
Since it is extremely difficult to create a lenticular lens capable of obtaining the same effect as the checkered masking arrangement, it is visually recognized as a three-dimensional image in both the horizontal and vertical directions. A possible image panel cannot be obtained with a conventional configuration using a lenticular lens. Therefore, it is possible to obtain an image panel that can be visually recognized as a three-dimensional image even with various complicated designs by a simple manufacturing method.
[0044]
Next, the stereoscopically visible image panel according to the seventh aspect of the present invention can be configured by changing the vertical / horizontal dimension ratio of the tile in the screen, and the vertical / horizontal dimension ratio of masking also corresponds to the tile. And set. At this time, as for the dimensional ratio, a plurality of types of dimensions may be set in at least one of the vertical and horizontal directions in addition to making the vertical and horizontal directions different. In the seventh aspect, the brightness and hue of the screen can be partially changed, and a portion that can be seen more and a portion that can be seen less can be differentiated.
[0045]
Furthermore, in this aspect, the image panel that appears stereoscopically is not divided into tiles by the same square as described above, but is divided into parallelogram pieces, for example, and the divided pieces are the same as in the case of tiles. 1 symbol is U, 2nd symbol is V, each piece is U in a matrix form with subscript hk _hk , V _hk (hkmn is a positive integer, hk is an odd number, 1 ≦ h ≦ m, 1 ≦ k ≦ n). _hk Piece V to the right of _hk And U _hk And V _hk Keeps the original symbol matrix arrangement, alternating each piece regularly, or piece U for the same subscript. _hk Tiles V diagonally below _hk And U _hk And V _hk Are arranged in a matrix pattern of the original symbols, and each piece is arranged alternately and regularly to form an array symbol S, which is the back surface of the transparent substrate 1 having a predetermined thickness. Masking having a size corresponding to 2 pieces by 2 pieces is provided on the surface of the transparent substrate 1 corresponding to each piece position of the arrangement pattern for each check position of the checkered pattern.
[0046]
In addition, the image panel according to the eighth aspect of the present invention has a two-dimensional pattern as in the second aspect using the configuration of the parallax pattern in any of the fifth aspect to the seventh aspect. From a different perspective A total of four parallax patterns obtained. Then, an image panel in which different images can be visually recognized as a three-dimensional image by changing the viewpoint is obtained.
[0047]
Next, a method for easily and quantitatively producing a parallax pattern will be described. A method of manufacturing a stereoscopically visible image panel according to the present invention includes (a) preparing two design forming means, one gazing point, and at least one subject, and (b) providing two design forming means. A single point of sight is arranged with a macroscopic parallax angle away from the point of sight, and the midpoint of the parallax line segment connecting the positions of the two symbol forming means is connected to the one point of sight. (C) projecting the subject between the parallax line segment and the gazing point onto the center line segment at a distance from the gazing point to the position farthest from the gazing point in the subject; The subject is arranged so that the ratio of the distance from the viewpoint to the parallax line segment is 1: 2.5 to 1: 3.5. (D) Each subject is seen from each symbol forming unit by each symbol forming unit. It includes the steps (a) to (d) for forming a pattern of a subject to obtain a parallax pattern.
[0048]
As the symbol forming means, a device capable of looking at the subject from a specific position and copying the symbol is used. Any imaging means such as a well-known camera or imaging means such as a CCD can be used as long as the subject can be seen from the specified position and the design can be copied. If the copied pattern is image data represented by digital data, various image processing can be performed immediately, which is preferable.
[0049]
In addition, if the arrangement position of the pattern forming means is described, it is natural that it can be installed at two places on the horizontal plane with respect to the vertical line, that is, on the floor surface of a normal room, but on the vertical line across the horizontal plane. 2 places, that is, two places above and below the horizontal plane at a certain distance from the floor. Furthermore, you may install in four places of two places on the horizontal surface, and two places made into the upper and lower sides on the horizontal plane, or in multiple places including these four places.
[0050]
Furthermore, in the method for manufacturing an image panel according to the present invention, the ratio of the distance from the gazing point to the position farthest from the gazing point in the subject and the ratio of the parallax line segment is 1: 0.10 to 1: Within a range of 0.14, the angle formed by the straight line on which the symbol forming means views the gazing point and the center line may be in the range of 1 to 3 degrees.
[0051]
If within the range of the ratio and the range of the angle, the length of the parallax line segment is separated by the macroscopic parallax angle, and the stereoscopic effect is obtained when viewing the image panel with the viewpoint shifted left and right and up and down. It is configured so that the effect to be obtained can be emphasized, and settings for viewing each subject can be easily and quantitatively obtained. Macroscopic parallax refers to parallax between human eyes.
According to the above method, parallax symbols can be obtained quantitatively with high reproducibility with simple settings using an image forming means that is usually well-known without requiring special skill.
[0052]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
[0053]

R _n And divide the linear strip into L ₁ , R ₁ , L ₂ , R ₂ , ... L _n , R _n A linear strip L _i And R _i Were arranged in the division order (in ascending order of the subscripts) and arranged as an array design S as a single design.
[0056]
However, the subscript n is a positive integer that is arbitrarily designated, i represents 1, 2,..., N, and the broken line is omitted in the figure. ₁ , L _i , L _n Was illustrated. The same applies to the following second to fourth embodiments.
For example, as shown in FIG. 1, the order in which the subscripts are added is the order from the left toward the paper surface of this specification.
[0057]
Then, as shown in FIG. 1A, the array pattern S was directly printed on the back surface of the acrylic transparent substrate 1 having a thickness of about 3 mm by screen printing. On the other hand, the set of linear bands (L _i , R _i ) The black masking 3 having the same width as two widths, that is, about 0.16 mm in width, in a state in which a plurality of the masking 3 are arranged in a spaced manner with an interval of the same width as the width of the masking 3 Each pair of bands (L _i , R _i ) In parallel with the transparent substrate 1 and in stripes by screen printing so as to be in a position corresponding to (in this embodiment, a masking 3 is provided at a position corresponding to an odd set of subscripts i). An image panel was created by printing directly and creating a three-dimensional image.
[0058]
The three-dimensional image panel can be visually recognized as a three-dimensional image when viewed from a position slightly away from the slit side of the stripe on the surface. In addition, a backlight (electrical accessory) was disposed on the back surface of the transparent substrate 1 and the image panel was viewed using this backlight, so that it could be visually recognized as a bright and extremely vivid three-dimensional image.
[0059]
In the first embodiment, a plurality of two parallax symbols respectively obtained from two different viewpoints with respect to a flower symbol (original drawing) given a three-dimensional effect by three-dimensional image processing.

L _n , R _n A linear strip L _i And R _i Are printed on the transparent substrate 1 in a state where they are alternately adjacent and arranged in the division order (in ascending order of the subscripts), but the parallax pattern is viewed from two different viewpoints on the same plane. It is not limited to the two seen.
[0060]
That is, four viewpoints of left and right and the center or two left and right, respectively, or three or four parallax symbols viewed from the left and right and different points, and each of these parallax symbols is divided into a plurality of linear bands. The linear strips may be printed on the transparent substrate 1 in a state of being arranged so as to be adjacent to each other in the divided order.
[0061]
Moreover, even when the left and right different viewpoints were increased to three or four, the same visual effect as in the case of two places was obtained when viewed as a three-dimensional image panel.
[0062]
In addition, the symbols may be not only a plurality of floral symbols but also a combination of various arbitrary symbols such as a bird symbol and an animal symbol as appropriate.
[0063]
Embodiment 2:
The stereoscopically visible image panel (stereoscopic changing image panel) according to this embodiment is an image panel in which different images can be stereoscopically viewed by changing the viewpoint, and the configuration thereof will be described in the order of the manufacturing process. First, as shown in the cross section of the main part in FIG. 2, for example, for each of the individual flower (not shown) and bird (not shown) pictures, The design was given a three-dimensional effect by three-dimensional image processing.
[0064]
After that, two parallax symbols (flower parallax symbols La and Ra (not shown) and bird parallax symbols Lb and Rb) obtained from different viewpoints of the flower symbol and the bird symbol are respectively obtained. (Not shown)) and each of the two obtained parallax symbols is divided into a plurality of linear strips La each having a width of about 0.16 mm. ₁ , La ₂ , ..., La _i ,… La _n , Ra ₁ , Ra ₂ , ..., Ra _i ,… Ra _n , Lb ₁ , Lb ₂ , ..., Lb _i ,… Lb _n , Rb ₁ , Rb ₂ , ..., Rb _i ,… Rb _n The linear strips obtained by dividing the different parallax symbols into ₁ , Ra ₁ , Lb ₁ , Rb ₁ , La ₂ , Ra ₂ , Lb ₂ , Rb ₂ , ... La _i , Ra _n , Lb _n , Rb _n Arrange as follows.
[0065]
In other words, “La _i , Ra _i , Lb _i , Rb _i Are arranged in the division order by alternately adjoining the linear bands obtained from the parallax patterns so that each set is adjacent in ascending order of the subscripts. Then, the array design S arranged as a single design was taken out of the computer.
[0066]
After that, as shown in FIG. 2, the array pattern S is directly printed on the back surface of the light red acrylic transparent substrate 1 having a thickness of about 5 mm by screen printing. Each pair of linear strips (La) has a width equal to the width of two linear strips, that is, a red masking 3 having a width of about 0.32 mm, separated by an interval of the same width as the masking 3. _i , Ra _i , Lb _i , Rb _i ) Position corresponding to the position (linear band La _i And Ra _i The three-dimensional changing image panel was created by printing directly in a stripe shape by screen printing in parallel through the transparent substrate 1 so that the stripe 3 is provided at the position of
[0067]
When the three-dimensional changing image panel was viewed from a position slightly away from the slit side of the stripe on the surface while slightly shifting the viewpoint from side to side, a three-dimensional image of a flower pattern and a bird pattern could be visually recognized by changing.
[0068]
Since the three-dimensional changing image panel is made of a light red acrylic and the masking 3 is provided by red printing, the three-dimensional changing image panel is more reddish than the three-dimensional image panel according to the first embodiment. There is an advantage that an image panel can be obtained by selecting a background color suitable for the type of the original image. As described above, the image panel using the colored transparent substrate 1 can also be implemented in the first, third, and fourth embodiments.

[0070]
Then, the synthesized symbols having perspective and stereoscopic effect are two parallax symbols L and R obtained from different viewpoints, and the two parallax symbols L and R are each about 0.08 mm. Multiple linear strips L in width ₁ , L ₂ , ..., L _i ,… L _n , R ₁ , R ₂ , ..., R _i ,… R _n The linear band obtained by the division is divided into L ₁ , R ₁ , L ₂ , R ₂ , ... L _n , R _n A linear strip L _i And R _i Is taken out from the computer in a state of being arranged adjacent to each other in the division order (in ascending order of subscripts) so as to be alternately adjacent to each other, and this array design S is shown in FIG. As described above, offset printing was performed on the surface of the polyester film 1a having a thickness of about 0.01 mm.
[0071]
On the other hand, on the back surface of the polyester film 1b having a thickness of about 0.01 mm, a black masking 3 having the same width as the two linear bands, that is, a width of about 0.16 mm, is the same as the width of the masking 3. A plurality of lines were offset and printed in stripes at intervals of the width.
The thickness of the polyester film is preferably thin so as not to impair the visual effect obtained by the arrangement pattern and masking.
[0072]
And the surface (printing surface) of the polyester film 1a which printed on the surface the synthetic | combination design which the design of the said coin and the English character was synthesize | combined is adhere | attached on the back surface of the polycarbonate transparent substrate 1 about 3 mm thick with a transparent adhesive. At the same time, the back surface (printing surface) of the polyester film 1b on which the stripe-shaped masking 3 is printed on the back surface, _i , R _i ) (In this embodiment, the masking 3 is provided at a position corresponding to an odd set of subscripts i) and the transparent substrate 1 so as to be parallel to the transparent substrate 1. A three-dimensional perspective image panel was prepared by bonding to the surface with a transparent adhesive.
[0073]
In this three-dimensional perspective image panel, a three-dimensional image having a sense of perspective in a state where an English character design floated in front of the coin design was visible.
[0074]
Further, in this stereoscopic image panel, various designs 2 and masking 3 can be formed on a thin polyester film by offset printing, so that a high-precision printed design can be obtained and viewed as a stereoscopic image. Even sharper images.
[0075]
Embodiment 4:
The stereoscopically visible image panel (stereoscopic dynamic form change image panel) according to the present embodiment is an image panel in which a plurality of different forms of dynamic images appear stereoscopically, and the configuration thereof will be described according to the order of the production steps.

ML _n , MR ₁ , MR ₂ , ..., MR _i , ... MR _n , NL ₁ , NL ₂ , ..., NL _i , NL _n , NR ₁ , NR ₂ , ..., NR _i , ... NR _n , PL ₁ , PL ₂ , ..., PL _i , ... PL _n , PR ₁ , PR ₂ , ..., PR _i , ... PR _n This linear band with different parallax patterns is divided into ML ₁ , MR ₁ , NL ₁ , NR ₁ , PL ₁ , PR ₁ , ML ₂ , MR ₂ , NL ₂ , NR ₂ , PL ₂ , PR ₂ , ..., ML _n , MR _n , NL _n , NR _n , PL _n , PR _n Arrange as follows.
[0076]
In other words, “ML _i , MR _i , NL _i , NR _i , PL _i , PR _i ”As a set, each set is adjacent to each other in ascending order of subscripts, that is, linear bands obtained from the parallax symbols are alternately adjacent to each other and arranged in the division order. Then, the image pattern A was created by directly printing the array pattern S as a single pattern by screen printing.
[0077]
On the other hand, on the surface of another colored (light blue) film 1c made of a polyester film having a thickness of about 1 mm, the number of viewpoints different from the number of dynamic symbols, that is, the number “2”, which is one less than “3”, “2”. “4” linear band width masking 3 is multiplied by the same width as the number of different viewpoints “2” for one dynamic symbol, ie, the same width as the width of the linear band. The number of linear bands of the number “6”, which is obtained by multiplying the number of target symbols “3” by the number of different viewpoints “2”, is set to 1 pitch, and the set of the linear bands (ML _i , MR _i , NL _i , NR _i , PL _i , PR _i A stripe film B was produced by direct printing in a stripe shape by screen printing so that the film was in a position parallel to each of the above.
[0078]
In addition, the dynamic design by the said linear strip may be provided in the back surface of the transparent substrate 1, and you may provide the masking 3 also in the back surface of the film 1c.
[0079]
The image substrate A and the stripe film B are made to correspond to the front surface (printing surface) of the image substrate A and the back surface of the stripe film B, and each masking 3 corresponds to each set (ML _i , MR _i , NL _i , NR _i , PL _i , PR _i ) So that the stripe film B can be moved relatively in parallel to the left and right, that is, in the direction perpendicular to the direction of the stripe, in parallel with the stripe film B so as to be in a position corresponding to the position of 11 and the like were provided endlessly to create a three-dimensional dynamic shape change image panel.
[0080]
In this three-dimensional dynamic form change image panel, the state in which one animal dynamically changes into three forms can be visually recognized as a three-dimensional image by sliding the stripe film B to the left and right.
[0081]
The number of dynamic symbols having the dynamic change is not limited to three forms, and may be four or more.
[0082]
As described above, in the first to fourth embodiments, each linear strip obtained from a plurality of parallax symbols is alternately adjacent to each other and arranged in a divided order so as to form a single symbol. Although the example provided in the above has been described, the method of providing this is not limited to printing, and may be a method of pasting a film once printed on a transparent substrate.
[0083]
In addition, in the first to third embodiments, the positional relationship between the masking 3 and the linear band has been described as the corresponding positional relationship. However, if the respective pitches are the same, what number linear shape is used. The positional relationship such that the set of bands comes directly under the masking 3 may be shifted.

W ₁ (W ₁ > W ₂ > W _Three > W _Four As shown in (...), the parallax pattern can be divided so that the width gradually decreases toward the central portion. An array symbol is configured from the parallax symbols thus divided in the same manner as in the first to fourth embodiments.
[0085]
The masking width is configured to correspond to the stripe width, and the configuration other than the stripe and masking is the same as in the first to fourth embodiments. The method of changing the width of the stripe may be set as shown in FIG. 5B, for example, but can be variously set such that the width gradually increases toward the central portion.
[0086]
With this configuration, the masking width is also set according to the stripe, so the distribution of the thick and thin masking varies depending on the location, and the brightness and color tone of the screen can be changed partially, or more parts can be seen It can be differentiated from the part that shows less.
[0087]
Embodiment 6:

In this way, the array design S as a single design. _H And the arrangement pattern S _H Is provided on the back surface of the transparent substrate 1 having a thickness of about 3 mm.
[0097]
Next, the size of 2 tiles by 2 columns, that is, 0.32 mm square masking on the surface of the transparent substrate 1 corresponds to each tile position of the array pattern for each checkered pattern. Arranged. 10 and 11, the positions where the masking M is provided are indicated by broken lines so as to correspond to the tile arrangement of the arrangement pattern S.
[0098]
As shown in FIG. 8, the type {circle around (2)}, which is another example of the present embodiment, shows that each tile obtained by dividing the tile into the same square is represented by A in the first left column according to the same matrix display. ₁₁ , B _{twenty one} , A ₃₁ , B ₄₁ A ... _h1 , B _{h + 1,1} A ... _m1 , B in the first right column ₁₁ , A _{twenty one} , B ₃₁ , A ₄₁ , ..., B _h1 , A _{h + 1,1} , ..., B _m1 …………, the kth left column is A _1k , B _2k , A _3k , B _4k ・ ・ ・ …… A _hk , B _{h + 1, k} A ... _mk , The kth right column is B _1k , A _2k , B _3k , A _4k , ..., B _hk , A _{h + 1, k} , ..., B _mk , The (k + 1) th left column is A _{1, k + 1} , B _{2, k + 1} , A _{3, k + 1} , B _{4, k + 1} ・ ・ ・ …… A _{h, k + 1} , B _{h + 1, k + 1} A ... _{m, k + 1} , The (k + 1) th right column is B _{1, k + 1} , A _{2, k + 1} , B _{3, k + 1} , A _{4, k + 1} , ..., B _{h, k + 1} , A _{h + 1, k + 1} , ..., B _{m, k + 1} Arrangement design S by connecting all tiles _T Is made.
[0099]
In this way, the array design S as a single design. _T And the arrangement pattern S _T Is provided on the back surface of the transparent substrate 1 having a thickness of about 3 mm.
[0100]
Next, the size of 2 tiles by 2 columns, that is, 0.32 mm square masking on the surface of the transparent substrate 1 corresponds to each tile position of the array pattern for each checkered pattern. Arranged.
[0101]
In order to explain the regularity of the alternating arrangement described above, h and k are described assuming an odd number, but this is not a requirement. If it is an even number, A and B in h rows or k columns are odd numbers. In reverse, it can be expressed by replacing it.
[0102]
For example, in FIG. 7, if k is an even number, the k-th column is B _1k , A _1k , B _2k , A _2k , B _3k , A _3k , ..., B _hk , A _hk , ..., B _mk , A _mk , K + 1 column is A _{1, k + 1} , B _{1, k + 1} , A _{2, k + 1} , B _{2, k + 1} , A _{3, k + 1} , B _{3, k + 1} A ... _h1 , B _h1 ・ ・ ・ …… A _{m, k + 1} , B _{m, k + 1} It is.
[0103]
FIG. 9 shows an arrangement of two types of tiles when h and k are odd numbers. For two tiles with the same coordinate display, (a) of FIG. 9 shows when k is an odd number, and parallax symbol 2 _A Below the second parallax pattern 2 _B Array design S _H 9 (b) shows the case where h is an odd number, and parallax symbol 2 _A 2nd parallax pattern 2 to the right of _B Array design S _T Get. Therefore, if h and k are even numbers, as shown in FIGS. 9C and 9D, the presence or absence of hatching is reversed.
[0104]
With the arrangements of the type (1) and type (2), the array pattern can be obtained by shifting the line of sight in the horizontal direction with respect to the image panel, and also when the line of sight is shifted in the vertical direction. An image panel that has a three-dimensional effect and can be visually recognized as a three-dimensional image is obtained. An image panel that can be visually recognized as such a stereoscopic image cannot be obtained with a conventional configuration using a lenticular lens. Therefore, it is possible to obtain an image panel that can be visually recognized as a three-dimensional image even with various complicated designs by a simple manufacturing method.
[0105]
In the description of the present embodiment, the case where the present invention is applied to an image panel that appears stereoscopically by changing the viewpoint has been described. However, by referring to the description of the second to fourth embodiments, the second embodiment is described. It is possible to easily change the stereoscopically visible image panel related to -4 to a stereoscopically visible image panel by changing the viewpoint left and right and up and down.
[0106]
Embodiment 7
Next, the stereoscopically visible image panel according to the seventh aspect of the present invention will be described. According to the seventh aspect, in the array design, the vertical and horizontal dimension ratios of the tiles can be changed according to the position of the tile, and the vertical and horizontal dimension ratios of the masking are also changed for the respective tiles. Set according to.
[0107]
FIG. 12 shows the vertical and horizontal dimensions of the tile, for example, in (a), the horizontal is x. ₁ , Y is vertical ₁ (y ₁ > x ₁ ) Form a parallax pattern, and in (b), the side is x ₁ , Y is vertical ₁ , Y ₂ , Y _Three , Y _Four ... y ₁ (y ₁ > y ₂ > y _Three > y _Four As shown in (...), the parallax pattern is configured such that the vertical width gradually decreases toward the central portion. The vertical dimension and the horizontal dimension of the tile can be changed as long as the shape dimensions can form a parallax pattern by arranging the tiles.
[0108]
With this configuration, the image panel of this aspect has different masking density depending on the location, and the brightness and color of the screen may be partially changed, or the portion that can be seen more and the portion that can be seen may be differentiated. it can.
[0109]
Furthermore, in this aspect, the stereoscopically-viewable image panel described in the sixth embodiment is not tile-divided by the same square as described above, but, for example, parallel as shown in (c) and (d) of FIG. The array symbol S can be formed by dividing it into quadrilaterals (hereinafter referred to as pieces).
[0110]
That is, the parallax symbol is divided into the parallelogram pieces described above, and the divided pieces are divided into matrixes by the first symbol U, the second symbol V, and each piece subscript hk, as in the case of tiles. (The positional relationship of each piece as shown in FIG. 12 (c)) _hk , V _hk (hkmn is a positive integer, hk is an odd number, 1 ≦ h ≦ m, 1 ≦ k ≦ n)
(1) Type: Piece U for the same subscript _hk Piece V to the right of _hk And U _hk And V _hk Is a regular alternating arrangement of each piece, maintaining the original array of symbols, or
(2) Type: Piece U for the same subscript _hk Diagonally below (U shown in FIG. ₁₁ And U ₁₂ Position V) _hk And U _hk And V _hk Constitutes an array symbol S which is a single symbol by arranging each piece regularly and alternately while maintaining a matrix arrangement of the original symbols.
[0111]
Then, the arrangement pattern S is provided on the back surface of the transparent substrate 1 having a predetermined thickness, and masking having a size of two pieces and two columns is provided on the surface of the transparent substrate 1 for each checkered pattern position. It arrange | positions so that it may correspond to each piece position of the said arrangement | sequence symbol.
By constructing the array pattern S using a piece shape such as a parallelogram, an oblique image can be emphasized.
[0112]
Embodiment 8:
The image panel according to the eighth aspect of the present invention has a parallax symbol structure when the two types of parallax symbols obtained from different viewpoints are used as the two types of symbols as in the second aspect. Can be obtained using the parallax pattern configured in any of the fifth to seventh aspects, and an image panel in which different images can be visually recognized as a three-dimensional image by changing the viewpoint is obtained.
[0113]
In such a configuration, since the masking dimension is also set in accordance with the dimension of the piece, the brightness and color of the screen can be partially changed, and the part that can be seen more can be differentiated from the part that can be seen more.
[0114]
As described above, also in Embodiments 5 to 8, in each case of each linear band, tile, and piece respectively obtained from a plurality of parallax symbols, these are arranged in the original arrangement order to form a single symbol. However, the method of providing this is not limited to printing, and may be a method of pasting a film once printed on a transparent substrate.
[0115]
Embodiment 9:
A method for obtaining a parallax pattern according to the present invention quantitatively with good reproducibility will be described. In this method, (a) two symbol forming means, one gazing point, and at least one subject are prepared, and (b) two symbol forming means are set to a parallax angle with respect to the one gazing point. (C) a parallax line segment that is arranged toward the gazing point at a distance and connects the midpoint of the parallax line segment that is a line segment connecting the positions of the two symbol forming means and the one gazing point. The ratio of the distance from the point of sight to the center line segment and the distance from the point of sight to the parallax line segment of the subject between the gazing point and the gazing point The subject is arranged so as to be 1: 2.5 to 1: 3.5, and (d) a symbol pattern is obtained by forming a symbol of the subject when the subject is viewed from each symbol forming unit by each symbol forming unit. Steps (a) to (d) are included.
[0116]
As the symbol forming means, a device capable of looking at the subject from the specified position and copying the symbol is used. In the present embodiment, two optical cameras are prepared and installed on the indoor floor.
[0117]
FIG. 13 is an explanatory plan view schematically showing the positional relationship between the symbol forming means for easily obtaining the array symbols and the arrangement of the subjects, and FIG. 14 is an array showing the arrangement state of the stripes representing each subject. It is explanatory drawing which shows an example of a symbol.
[0118]
As shown in FIG. 13, in order to carry out the step of obtaining a parallax symbol according to the present invention, first, (a) one gaze point F and two symbol forming means C ₁ And C ₂ And at least one subject Ω is prepared. Here, 3 subjects ₁ ~ Ω _Three Got ready. The arrangement positions of these symbol forming means will be described.
[0119]
Next, (b) two symbol forming means C ₁ And C ₂ Are arranged toward the gazing point F so as to be separated from the one gazing point F by the naked-eye parallax angle 2φ. At this time, the two symbol forming means C ₁ And C ₂ Parallax line segment L that is a line segment connecting the positions of _P Midpoint P _F And the center line segment L connecting the one gaze point F _C That's it.
[0120]
Next, (c) the subject is arranged between the parallax line segment and the gazing point so that the following condition is satisfied. That is, subject Ω ₁ ~ Ω _Three Position P farthest from the point of gaze ₀ DΩ projected from the gazing point F to the center line segment and the distance D from the gazing point to the parallax line segment _C The subject is arranged so that the ratio of the ratio is 1: 2.5 to 1: 3.5 (ratio 1).
[0121]
At this time, the distance from the gazing point to the position farthest from the gazing point in the subject (the projection DΩ) and the parallax line segment L _P And the ratio between the straight line and the center line segment L where the symbol forming means looks at the gazing point, is within a range of 1: 0.10 to 1: 0.14 (ratio 2). _C Is preferably in the range of 1 degree to 3 degrees.
[0122]
As long as the ratio is within the range (ratio 1 and ratio 2), the length of the parallax line segment is three-dimensional when the image forming means separates the visual parallax angle and the viewpoint is shifted left and right and up and down. It is configured so that the effect of obtaining a feeling can be emphasized, and settings for viewing each subject can be easily and quantitatively obtained. Here, the naked-eye parallax refers to the parallax between human eyes. In addition, if the angle is within the range, a positional relationship for obtaining a parallax design in which the effect of the three-dimensional effect is enhanced by the design can be realized.
[0123]
Then, (d) each symbol forming means looks at the subject and forms a symbol representing the subject to obtain a parallax symbol. Therefore, a parallax pattern can be obtained quantitatively with high reproducibility with a simple setting by using an image forming means that is usually well known without requiring special skill. Thereafter, an array pattern was prepared. An example is shown in FIG.
[0124]
The three-dimensional image panel manufacturing method according to the present invention is characterized by including such steps (a) to (d), and steps other than (a) to (d) are the same as those in the first embodiment. As described in -8. Further, in these steps (a) to (d), in actuality, a pattern can be produced by setting the above-described distance and angle on the “shade”.
[0125]
As described above, the present invention reliably obtains a parallax pattern quantitatively with high reproducibility with a simple setting using an image forming means that is usually well-known, without requiring special skill or the like.
[0126]
【The invention's effect】
In the present invention, in place of the conventional mold-shaped kamaboko-shaped lenticular lens, the pattern provided on the back surface of the transparent substrate through a striped mask formed by direct printing or bonding to the surface of the transparent substrate In addition to the three-dimensional changing image panel, the three-dimensional perspective image panel, and the three-dimensional dynamic form change image panel, various designs can be visually recognized as a three-dimensional image. Visible as changing or dynamic images.

In addition, a stereoscopic image obtained by the kamaboko lenticular lens cannot provide a stereoscopic visual effect when viewed with one eye, but the image panel according to the present invention can provide a stereoscopic visual effect even when viewed with one eye. That is, according to the lenticular lens, as described above, the shadowed portion of the lens curved surface cannot be seen. For example, the pattern to be seen with the left eye cannot be seen with the right eye. However, since the image panel according to the present invention has a flat surface, it is possible to see both the design seen with the left eye and the design seen with the right eye even with one eye, so that a three-dimensional visual effect can be obtained with one eye. It is done.
[0128]
Therefore, since there is no need for a mold for forming a semi-cylindrical lenticular lens, the manufacturing cost can be greatly reduced by forming everything by printing. An image panel with better visual effect than the lenticular lens system can be provided at a low price.
[0129]
Furthermore, the image panel according to the present invention can configure an array design by setting a plurality of types of stripe dimensions and tile shapes and dimensions in the parallax design, partially changing the brightness and color of the screen, and more. It is possible to differentiate between the part that shows more and the part that shows less.
[0130]
In addition, three-dimensional images and stripe-shaped masking can be formed by ordinary printing techniques, etc., so even three-dimensional images and stripe-shaped masking can be directly printed on thick transparent substrates by screen printing. The degree of freedom in design is high, and the utility value in the advertising or decoration field is high.
[0131]
In addition, the three-dimensional image panel manufacturing method, including the parallax pattern manufacturing method according to the present invention, does not require particularly technical skill or the like, and generally uses well-known image forming means (symbol forming means). It is possible to reliably obtain a parallax pattern with a simple setting and quantitatively reproducible.
[0132]
Therefore, it can be said that the industrial applicability of the present invention is extremely large.
