Description

  The present invention relates to a method for using a stereoscopic photograph creation computer and a stereoscopic photograph creation method for obtaining a composite image that can be stereoscopically viewed under a lenticular screen after dividing a plurality of two-dimensional images into a plurality of stripe images. .

  Stereophotographs using a lenticular screen are created by dividing multiple images taken from multiple directions into striped images and then combining them. Observe each stripe image with separate left and right eyes through the lenticular screen. The two-dimensional image can be seen stereoscopically without wearing stereoscopic glasses.

  As shown in FIG. 7, the lenticular screen 50 is a sheet-like member in which a large number of lenticular lenses 51 having a cross-sectional cross section and a pitch p of about 100 μm are connected, and obtained from a plurality of viewpoints under one lens 51. The images represented as pixels having the same coordinates in each image are arranged as adjacent stripe images A, B, C, and D according to the viewpoint arrangement.

  When each stripe image is observed through the lenticular screen 50, it is split and incident on the observer's eye, but the observer's right eye and left eye observe the single lenticular lens 51 from different angles. Different stripe images are incident at the same viewpoint. For example, in FIG. 7, the observer's right eye 52 sees the stripe image C and the left eye 53 sees the stripe image B, and the different image information entered from the left and right eyes is combined to create a stereoscopic view. It can be done.

  Conventionally, an optical recording method has been used to create such a stripe composite image. This is a method of photographing a subject from many viewpoints using a camera or other photographing means to obtain a plurality of negatives, and printing these negatives onto a single photographic plate through a magnifying lens and a lenticular screen for composition. Each negative image projected on the lenticular screen was divided into the width W of the lenticular lens and condensed to form a plurality of stripe images that were printed on the photographic plate.

  Projection and printing of a plurality of negatives were sequentially performed from different angles by changing the relative positions of the negative, the magnifying lens, and the synthesizing lenticular screen. At that time, the negative images were projected at the same magnification, and the central images of the respective subjects were projected on the synthesizing lenticular screen, so that the foreground and background images of the central image were determined by the respective negatives. It was projected at a different position. These stripe images were recorded at different positions as shown in FIG. 7 in the area of the photographic plate corresponding to each lenticular lens.

  However, according to the conventional optical recording method, a complicated optical system for projecting a parallax image onto a lenticular recording material is necessary, and fine adjustment is also required for projection and printing of negatives. There was a problem that it was difficult to create. Therefore, due to remarkable progress in computer technology in recent years, there are various stereoscopic photo creation methods in which a stripe image is created in advance as image data on a computer and printed on a recording medium such as paper by a printing apparatus based on the image data. Has been proposed.

As a method of forming an image that can be stereoscopically viewed by being arranged on the back side of the lenticular screen using a computer equipped with image system software, for example, there has been a conventional technique as described below.
JP-A-8-22091 JP 2003-43599 A

  In order to obtain a plurality of parallax images, a conventional stereo picture creation computer uses a stereo camera, a compound eye camera, or a single camera at appropriate intervals and photographs them with synchronized shutters. The parallax image was read into the computer by an image input device such as an image scanner. The image processing unit of the computer system divides the plurality of input parallax images into stripe images having appropriate widths according to the lens width W of the lenticular screen, and further compresses the images, and then the image synthesis unit connects the stripe images. They are combined and combined to create a single stripe image file, and the image signal of this image file is input to a printer to output a combined image for stereoscopic viewing.

  However, in the conventional stereoscopic photograph creation method, a combined image cannot be formed unless intermediate processing such as image compression is performed on a stripe image divided into an appropriate width, and a large amount of memory is required for storing and combining many divided images. For example, the computer system has a drawback of becoming more sophisticated and complicated. In recent years, with the widespread use of digital cameras, it has become common to import photos into personal computers (hereinafter abbreviated as “PCs”), edit them, and print them. A possible technique has not yet been disclosed.

  The present invention has been made to solve the above-described problems of the conventional method of using a computer for creating a stereoscopic photograph, and it is possible to easily generate a composite image for stereoscopic viewing even using a general-purpose personal computer. The object is to provide a method of using a computer that can be created.

  The method for using the computer for creating a three-dimensional photograph according to claim 2 allows the stereoscopic photograph under the lenticular screen to be stereoscopically viewed over the entire width, and the method for using the computer for preparing a three-dimensional photograph according to claim 3 is foreground / background. Both are intended to give a clear three-dimensional effect.

  The stereoscopic photograph creating method according to claim 4 combines a background image consisting of one viewpoint and a plurality of foreground images having parallax so that the background can be stereoscopically viewed even with a single image, and the stereoscopic photograph according to claim 5. The purpose of the creation method is to provide a method for creating a stereoscopic photograph in which a background image consisting of one viewpoint and a foreground image consisting of one viewpoint are combined, and each of the images can be viewed stereoscopically in both the foreground and background. Yes. According to the method of creating a stereoscopic photograph according to claim 6, when a composite image for stereoscopic viewing is created by dividing an image consisting of one viewpoint into stripe images, it can be easily created even using a personal household computer. The object is to provide a method for creating a stereoscopic photograph.

  In order to solve the above problems, the method of using the computer for creating a three-dimensional photograph of the present invention forms an image that can be stereoscopically arranged by placing it on the back side of a transparent lenticular screen using a computer equipped with image-based software. Therefore, there is provided a computer for creating a three-dimensional photograph having a dividing step for dividing a plurality of basic images into a plurality of stripe images, a combining step for combining the stripe images, and a printing step for printing a combined image for stereoscopic viewing. In the usage method, the dividing step includes an image layer on which the basic image is arranged, and a mask layer on the image layer on which a mask object is arranged, and the mask object has a lens pitch of a lenticular screen. Parallel to the narrow frame path to be arranged according to the size A comb-shaped object formed by combining all the thin frame-shaped paths connected to a connecting path, and masking the outside of the comb-shaped image with respect to the basic image to obtain one comb-shaped stripe image, The plurality of comb-shaped stripe images with respect to the plurality of basic images are sequentially shifted so as not to overlap each other, and the combining step arranges the stripe images of the corresponding coordinates of each basic image as adjacent stripe images according to the viewpoint arrangement, and stereoscopically displays them. It is characterized by obtaining a composite image.

  Computer image software can create layers that can be drawn separately for different elements for image layout and graphics creation, and has a mask function that can cut out and display arbitrary locations on images. Work on each layer. A layer is a layer of a transparent film superimposed on an image, and various processing operations can be performed without modifying the original image.

  In one mask layer, a narrow frame shape path with a width that divides the lens pitch size of the lenticular screen into a plurality of lenses is arranged for each lens, and the end or center portion is similarly combined with a narrow connection path to form a comb shape. Form an object. A mask is to hide a part of an image with image-based software, and the image is displayed according to a created path and the outside is hidden. The created mask range can be reused as needed by storing it as a dedicated channel for the mask.

  Although the same comb-shaped object is drawn in other mask layers, the thin frame-shaped paths corresponding to one lens position are shifted so as not to overlap each other. That is, the thin frame-shaped paths corresponding to one lens position formed in different mask layers are adjacent to each other when they are overlapped, and the total width is configured to be approximately equal to the lens width.

  For example, images with parallax are sequentially arranged in one image layer placed under one mask layer. The comb-shaped object and the image below the comb-shaped object are clipped into comb-shaped stripes by using a soft mask function to obtain a cut-out display effect. The other comb-shaped object and the image below it also obtain the same masking cutout effect to obtain a plurality of comb-shaped stripe images. Thereafter, a combined image for stereoscopic viewing is obtained by the combining function of the image system software.

  When a plurality of layers are combined, the images are integrated in a state where the mask is applied, and the hidden portions of each layer can be seen through, so that the respective stripe images are synthesized adjacent to each other. If a set of mask layers is created and saved, the images in the image layer can be linked and replaced as necessary, and can be applied to creating different stereoscopic photographs.

  The stripe image becomes a plurality of images corresponding to each lens, but the comb-shaped stripe image masked and cut out by the comb-shaped object is stored and synthesized as one image, so that a large memory capacity is not required. Also, since image compression is not performed, system operation is simplified.

  The method of using the computer for creating a three-dimensional photograph according to claim 2, wherein, in the dividing step, each fine frame shape path in one mask layer is marked, combined with another mask layer having no mark, and the mark is predetermined. Is obtained by placing the composite image under a lenticular screen and expanding the width of each narrow frame shape path so that the mark can be observed under each lens. is there.

  The narrow frame shape path first draws a thin frame on the layer with the pitch width equally divided by the number of mask layers to be used within the same dimensions as the lens pitch. When the mask layers at this time are combined, one aggregate of the thin frame-shaped paths has the same width as the lens width. When each thin frame shape path in one mask layer is colored, for example, as a mark and combined with another transparent mask layer, the colored thin frame is positioned, for example, on the left side in each lens pitch.

  When this composite image is placed under a lenticular screen and a colored mark is observed, a part that cannot be confirmed is generated. This needs to be different in a predetermined relationship between the pitch of the stripe image and the pitch of the lenticular lens, and the stripe image is shifted so that the stereoscopic photograph under the lenticular screen can be stereoscopically viewed over the entire width. If so-called center shift is not performed, a portion that cannot be visually recognized is generated.

  Therefore, in order to shift the center, the width of each stripe image is expanded so that the colored mark can be observed under each lens. For example, if the mark is initially located on the left side of each lens, the width of the narrow frame path is increased, and the adjacent mark moves slightly from left to right within the lens pitch. This enlarged width is adjusted so that the mark can be visually recognized over the entire width according to the size of the lenticular screen and the angle of the eyes of the observer. For example, when the lenticular screen is within A4 size, the rightmost mark is shifted so that it is located at the center of the pitch.

  The basic image in the method of using the three-dimensional photograph creation computer according to claim 3 is a plurality of composite basic images created by combining a plurality of background images with parallax and a plurality of foreground images with parallax. The synthesized basic image is created by combining one background image and one foreground image corresponding to each other.

  When shooting a basic image with parallax, since the foreground is generally focused, it does not match the background parallax, and if the composite image is created as it is, the background will be blurred. In order to give a clear stereoscopic effect to both the foreground and the background, the foreground and the background are photographed separately, and a combined basic image is created by combining the corresponding viewpoints.

  In the method for creating a stereoscopic photograph according to claim 4, a plurality of basic images are formed in order to form an image that can be stereoscopically arranged on the back surface of a transparent lenticular screen using a computer equipped with image system software. In this method, the basic image is a plurality of foreground images having a parallax with a background image consisting of a single viewpoint. In combination, and the background image is positioned on the left side with respect to the foreground image having the right viewpoint, and the background image is sequentially positioned on the right side with respect to the foreground image having the left viewpoint. The present invention is characterized in that a plurality of composite basic images are created by moving the background image and combining them.

  In general, the foreground is shifted to the left by a predetermined amount with respect to the background in the composite image for the right eye, and for the left eye, the foreground is shifted to the right by a predetermined amount, and each composite image is viewed by the right and left eyes, respectively. And the foreground image are perceived as different distances. Applying such a principle, the background image is from one viewpoint, but this is shifted in a plurality of composite basic images so that there is a depth in relation to the foreground image.

  For example, a foreground image subject with parallax is cut out, and a composite basic image is created in which a background image of one viewpoint is arranged on the left side for the subject having the right viewpoint. For subjects with different viewpoints, the background image is gradually shifted to the right to create a plurality of composite basic images with the background and foreground changed respectively. If these are divided and combined, a stereoscopic photograph having a stereoscopic effect on the foreground and the background can be obtained.

  According to the method of creating a stereoscopic photograph according to claim 5, a plurality of basic images are formed in order to form an image that can be stereoscopically viewed by being placed on the back side of a transparent lenticular screen using a computer on which image system software is installed. In the stereoscopic photo creation method of combining each stripe image and printing the stereoscopic composite image, the basic image includes a background image consisting of one viewpoint and a foreground image consisting of one viewpoint. A plurality of composite basic images created by combining the foreground image that sequentially shifts to the right side and the background image that sequentially shifts to the left side. is there.

  For example, prepare 4 foreground images and 1 background image of a person from one viewpoint, and the person is shifted to the right and the background is shifted to the left and the background is shifted to the left and the reverse sequentially. Four basic images are created in which the positional relationship between the person and the background is shifted. If these are divided and then combined, the background will be in the back and the person will be able to create a three-dimensional photograph that stands out in front of the lens screen.

  7. The method for creating a stereoscopic photograph according to claim 6, wherein when the composite basic image is divided into a plurality of stripe images, the method for using the stereoscopic photograph creating computer according to claim 1 is used. . A plurality of composite basic images created by using an image consisting of one viewpoint are also converted into a plurality of comb-shaped stripe images to obtain a composite image for stereoscopic viewing.

  In the method of using the computer for creating a stereoscopic photograph of the present invention, a comb-shaped stripe image to be stored as one image is obtained to form a composite image for stereoscopic viewing, so the number of divided images is drastically reduced and the memory required for the computer Less. Further, since image compression or the like is not performed, the system operation becomes simple, and a composite image for stereoscopic viewing can be easily created even with a general personal computer. If a set of mask layers is created and saved, the images in the image layer can be linked and replaced as needed, and can be applied to creating different stereoscopic photographs.

  According to the method of using the computer for creating a stereoscopic photograph according to claim 2, the width of each narrow frame shape path is expanded so that each of the marks can be observed by placing a composite image having the marks at predetermined intervals under the lenticular screen. A stereoscopic photograph that can be stereoscopically viewed over the entire width can be easily created.

  According to the method of using the computer for creating a three-dimensional photograph according to the third aspect, since the plurality of background images with parallax and the plurality of foreground images with parallax are created in combination, the foreground and background are clear without blurring the background. A stereoscopic photograph with a stereoscopic effect can be created.

  The stereoscopic photograph creating method according to claim 4 creates a composite basic image by combining a background image consisting of one viewpoint and a plurality of foreground images having parallax, and the stereoscopic photograph creating method according to claim 5 is based on one viewpoint. Since a composite basic image is created by combining a background image and a foreground image consisting of one viewpoint, a stereoscopic photograph having a stereoscopic effect can be obtained even for a single viewpoint image.

  According to the method for creating a stereoscopic photograph according to claim 6, since a plurality of composite basic images created using an image consisting of one viewpoint also obtain a plurality of comb-shaped stripe images and form a composite image for stereoscopic viewing. Even if a personal computer is used, a composite image for stereoscopic viewing can be easily created.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a mask layer screen in a computer in which image software is installed. A mask object 2 is placed on the mask layer 1 using graphic creation software. The mask object 2 is formed by combining the narrow frame-shaped paths 3 arranged at a predetermined interval and the connecting paths 4 connecting all of the plurality of narrow frame-shaped paths 3 in parallel, and is a comb-shaped object. Yes.

  The mask layer 1 is placed on the image layer where the basic image is placed, and is displayed according to the created path, and the outside is hidden. The created mask layer 1 can be reused as needed by storing it.

  A plurality of mask layers 1 are prepared according to the number of image layers, but the positions of the objects are sequentially shifted so as not to overlap each other. Details will be described with reference to FIG. FIG. 2 is a conceptual diagram showing a cross section of each mask object in a state where a plurality of mask layers are overlaid. In each mask layer 1, 101, 201, 301, comb-shaped objects 2, 102, 202, 302 having the same shape as mask objects are arranged.

  Here, the width of the thin frame shape path 3 is set to a width obtained by dividing the lens pitch size p of the lenticular screen 50 evenly by the number of mask layers. First, each narrow frame shape path 3 in the mask layer 1 is arranged so as to be positioned at the left end of each lens 51, and the next narrow frame shape path 103 of the mask layer 101 is arranged adjacently so as not to overlap therewith. Similarly, the thin frame-shaped paths 203 and 303 of the other mask layers 201 and 301 are also arranged adjacent to each other, and the total width of a set of these is configured to be substantially equal to the lens pitch p.

  Note that the length L of the narrow frame path 3 and the width W of the comb-shaped object 2 are matched to the size of the lenticular screen 50. The position of the connecting path 4 may be an arbitrary position.

  Next, the center of the comb-shaped object is shifted so that the stereoscopic photograph can be stereoscopically viewed over the entire width. This method will be described with reference to FIG. When each thin frame shape path 3 in the mask layer 1 is colored to be a mark and combined with the other transparent mask layers 101, 201, 301, the colored thin frame shape path 3 is initially included in each lens pitch p. For example, it is located on the left side. By combining these plural mask layers, a composite image in which the marks 3 are present at a predetermined interval is obtained.

  When this synthesized image is placed under the lenticular screen 50 and the mark 3 colored under each lens 51 is observed, a part that cannot be confirmed is generated. Therefore, the width of each narrow frame shape path 3, 103, 203, 303 is slightly enlarged. At this time, the adjacent mark 3 slightly moves from the left to the right within the lens pitch P. The enlarged width is adjusted so that the mark 3 can be visually recognized under all the lenses 51 according to the size of the lenticular screen 50 and the angle of the eyes of the observer. For example, when the lenticular screen 50 is within A4 size, the rightmost mark 3 is shifted so as to be positioned at the center of the pitch p.

  The mask layer for placing the comb-shaped object created in this way is placed on the image layer for placing the basic image. This state will be described with reference to FIGS. FIG. 4 is a conceptual diagram in which an image layer and a mask layer are overlaid, and FIG. 5 is a diagram for explaining an image cross section cut out by the overlaid mask object.

  In one image layer 5 placed under one mask layer 1, an image 6 composed of one viewpoint among images having parallax is arranged. Similarly, the image layer 105 below the mask layer 101 has an image 106 from the next viewpoint, the image layer 205 below the mask layer 201 has an image 206 from the next viewpoint, and the image layer 305 below the mask layer 301. Are arranged with images 306 formed from the last viewpoint. At this time, the image position is determined so that the coordinates of the centers of the images coincide.

  The comb-shaped objects 4, 104, 204, and 304 of the mask layers 1, 101, 201, and 301 mask the comb-shaped outside of the images 6, 106, 206, and 306, respectively, and comb-shaped stripe images 7 and 107, respectively. , 207, 307 are obtained. The comb-shaped stripe images 7, 107, 207, and 307 obtained in this way are combined by a combining function of image software to become a combined image for stereoscopic viewing.

  A method of creating various stereoscopic photographs using the mask layer on which the comb-shaped objects described above are arranged will be described. For example, a case where a plurality of background images with parallax and a plurality of foreground images with parallax are combined will be described with reference to FIG. FIG. 6 is an explanatory diagram of a procedure for creating a composite basic image. The foreground image 8 and the background image 9 are a plurality of images each having a parallax, and a combined basic image consisting of one viewpoint is obtained by combining one of the background images consisting of one viewpoint and the foreground image 8a clipped from the corresponding viewpoint. create.

  This composite basic image may be a combination of a background image consisting of one viewpoint and a plurality of foreground images having parallax, or may be created by combining a background image consisting of one viewpoint and a foreground image consisting of one viewpoint. . When using a background image consisting of one viewpoint and a foreground image with parallax, multiple background images are placed on the left side with respect to the foreground of the right viewpoint, and the background image is shifted to the right side with respect to the foreground of the left viewpoint. Create a basic image.

  When using a foreground image and a background image consisting of one viewpoint, for example, prepare 4 images each, and the foreground is sequentially shifted to the right and the background is sequentially shifted to the left. The four basic images in which the positional relationship between the foreground and the background are shifted are created by combining the objects. A plurality of composite basic images created using images from a single viewpoint are also formed as a plurality of comb-shaped stripe images, and if these are combined, a stereoscopic photograph with the background in the back and the foreground in the front of the lens screen can be created.
