Description

  The present invention relates to a display device, a stereoscopic image forming system, a display program, and an image forming program.

  As one of the modeling techniques, a 2.5-dimensional stereoscopic image forming technique using a foamable sheet is known, and is used, for example, for creating teaching materials for visually impaired persons such as Braille. As such a technique, for example, the techniques of Patent Documents 1 and 2 are disclosed.

  Patent Document 1 states that “a surface-inverted image of a desired image is formed on a surface of a sheet having a coating layer of a thermally expandable sheet having a coating layer containing thermally expandable microspheres on its surface. The heat-expandable microspheres in the coating layer are formed by using a forming material, selectively irradiating the heat-expandable sheet from the image-forming side, and selectively heating the image portion using the light absorption characteristics of the image-forming material. A “stereoscopic image forming method in which a stereoscopic image is formed by expansion” is disclosed. Patent Document 2 discloses a “foaming modeling system that selectively foams the foamed layer in a foamable sheet provided with a foamed layer on a base material layer, thereby modeling a semi-stereoscopic image”. .

  By the way, the techniques described in Patent Documents 1 and 2 do not consider displaying a stereoscopic image formed on a medium such as a thermally expandable sheet on a display device. For this reason, the techniques described in Patent Documents 1 and 2 cannot grasp the feel of the formed stereoscopic image unless a stereoscopic image is actually formed on the medium. Here, it is also conceivable to express a stereoscopic image using a cross-sectional view.

(First embodiment)
FIG. 1 is a configuration diagram of a stereoscopic image forming system according to the first embodiment of the present invention.
The stereoscopic image forming system 1000 includes a display device 100, a display operation unit 200, a two-dimensional image forming device 320, and a foaming device 310. The stereoscopic image forming device 300 includes the two-dimensional image forming device 320 and the foaming device 310. Configure.

  The display device 100 is a general-purpose information processing device connected to the display operation unit 200 using an OS (Operating System), and is used as a control device that controls the foaming device 310 and the two-dimensional image forming device 320. The display device 100 includes a control unit 10, a volatile storage unit 70, a nonvolatile storage unit 80, and a communication unit 90. The volatile storage unit 70 is a RAM (Random Access Memory) and is used as a work memory. The nonvolatile storage unit 80 is an HDD (Hard Disk Drive) or ROM (Read Only Memory), and stores an OS 81, an application program 82, a printer driver 83, image data 84, and the like. The communication unit 90 is a LAN (Local Area Network) or USB (Universal Serial Bus) serial interface or parallel interface. In this embodiment, the two-dimensional image forming apparatus 320 is connected by USB, and the foaming apparatus 310 is connected serially or in parallel. The display operation unit 200 is a touch panel connected to the display device 100, and includes a display unit that displays a two-dimensional image and an input unit that is input by an operator.

  The foaming device 310 uses a halogen lamp (not shown) as a heating device (heating device) in order to heat one or both sides of a medium in which a foam layer (expansion layer) that is foamed (expanded) by heat is laminated on one side. I have.

  The two-dimensional image forming apparatus 320 performs black printing (drawing) for foaming (expanding) a specific portion of a thermally expandable sheet as a medium, or color printing the entire surface of the medium with CMY (cyan, magenta, yellow). Inkjet printer. Here, the heat-expandable sheet is a sheet-like medium in which an expanded layer (foamed layer) that expands (foams) by heating is provided on the surface of the mount. The two-dimensional image forming apparatus 320 includes image data (surface data) of a specific portion that partially expands the expansion layer on the surface of the medium, and image data (back surface data) that partially expands the expansion layer from the back surface of the medium. Color image data is required. Here, the image data of the front surface data and the back surface data is also foam data for expanding the foam layer of the medium. That is, black printing is performed on an image printed on the thermally expandable sheet in order to partially expand the thermally expandable sheet (foamed sheet) to express a three-dimensional shape by undulation of the surface of the thermally expandable sheet. Do it.

  Since the halogen lamp strongly generates near-infrared light, black (carbon) is strongly heated, and the amount of heating is small at the CMY color printing location. For this reason, the medium having the foam layer is foamed (expanded) only at a specific portion printed in black, and so-called 2.5D printing is performed. In other words, the two-dimensional image forming apparatus 320 prints a heat conversion layer (black layer) that converts near infrared light as electromagnetic waves into heat. Here, the ink as the developer for black printing contains carbon, and the CMY ink does not contain carbon. For this reason, black mixed with CMY has a small amount of heat generation. Note that the stereoscopic image forming system 1000 operates as a structure manufacturing system for manufacturing a 2.5D structure.

  The control unit 10 is a CPU (Central Processing Unit), and functions of the preview image generation unit 20, the display control unit 30, the stereoscopic image formation control unit 40, and the communication control unit 50 by executing a program. Realize. The preview image generation unit 20 generates preview image data that simulates a stereoscopic image formed by the foaming apparatus 310 from a color original image. The preview image generation unit 20 includes a decolorization image generation unit 21, a decolorization reversal image generation unit 22, a contour extraction image generation unit 23, a contour reversal image generation unit 24, an image composition unit 25, and an emboss processing unit 26. Functional means are provided. The decolorized image generating means 21, the decolorized inverted image generating means 22, the contour extraction image generating means 23, the contour inverted image generating means 24, the image synthesizing means 25, and the embossing processing means 26 are printed on the thermally expandable sheet. Prior to printing of the image to be printed, it functions as an editing means for editing the image printed on the thermally expandable sheet.

  The decolorized image generation means 21 decolorizes the original image (grayscale) to generate a decolorized image 436 (see FIG. 10B). That is, the decolorized image generation means 21 calculates the luminance or brightness of the original image and sets it as a decolorized image. The decolored reversal image generation unit 22 inverts the density of the decolorization image generated by the decolorization image generation unit 21 to generate a decolorization reversal image 438 (see FIG. 10B). Further, the decolored inverted image generating means 22 may perform decoloring after inverting the density of the original image. The contour extraction image generation means 23 extracts the contour of the original image and generates a contour extraction image 431 (see FIG. 9B) as an edge enhanced image. The contour inversion image generation unit 24 inverts the density of the contour extraction image generated by the contour extraction image generation unit 23 to generate a contour inversion image 432 (see FIG. 9B). In addition, the contour inverted image generation unit 24 may extract the contour after inverting the shade of the original image.

  The image synthesizing unit 25 synthesizes a plurality of images of the decolorized image 436, the contour extraction image 431, the decolored inverted image 438, and the contour inverted image 432. That is, the image synthesizing unit 25 synthesizes one of the decolored image and the contour extraction image with a preset first contribution rate and the other with a second contribution rate obtained by subtracting the first contribution rate from 1 and a non-inverted synthesized image. (One composite image), a decolored image, and a contour reversal image, a first composite image obtained by combining one of them with a first contribution rate and the other with a second contribution rate obtained by subtracting the first contribution rate from 1. One of the image and the decolored inverted image is a first contribution ratio, and the other is synthesized with a second contribution ratio obtained by subtracting the first contribution ratio from 1, and one of the contour inverted image and the decolored inverted image. A third composite image is generated by combining the other with the first contribution ratio and the second contribution ratio obtained by subtracting the first contribution ratio from 1.

  Here, the first contribution rate x is 0% ≦ x ≦ 100%, and the second contribution rate y = (1−x) is 0% ≦ y ≦ 100%. That is, the non-inverted composite image may be a decolorized image 436 (FIG. 10B) or a contour extraction image 431 (FIG. 9B). The first contribution rate x and the second contribution rate y may be 0% <x, y <100%.

  The emboss processing means 26 performs emboss processing on a plurality of composite images (non-inverted composite image, first composite image, second composite image, and third composite image) composited by the image composition means 25, and generates respective emboss images. To do.

  The preview image (particularly the embossed image) displayed on the display operation unit 200 is a pseudo two-dimensional representation of a stereoscopic image after foaming (expansion). The embossed image is a three-dimensional pseudo display of a flat image (black print image). In particular, an embossed image makes it easier to grasp the feel and appearance of a formed stereoscopic image than a composite image of any one of a decolored image, a contour extraction image (edge-enhanced image), a decolored inverted image, and a contour inverted image. It is an image to be.

  The stereoscopic image formation control unit 40 controls the stereoscopic image forming apparatus 300. That is, the stereoscopic image formation control unit 40 controls the two-dimensional image forming apparatus 320 and the foaming apparatus 310 via the printer driver 83. Here, the stereoscopic image formation control means 40 causes the display operation unit 200 to display an image indicating that the medium is to be placed on the mounting table of the two-dimensional image forming apparatus 320 with the surface side facing up, and the surface data is displayed. Then, the image is formed (printed) on the medium, and then the display operation unit 200 displays an image indicating that “the back side of the medium is placed on the mounting table of the two-dimensional image forming apparatus 320”. The back surface data is used to form an image on the medium, and then an image to the effect that “the front side of the medium is placed on the mounting table of the foaming apparatus 310” is displayed on the display operation unit 200, and the foaming apparatus 310 is displayed. Let the medium heat.

  The communication control unit 50 is a control unit that controls the communication unit 90. Here, when the communication control unit 50 controls the two-dimensional image forming apparatus 320, the printer driver 83 is used.

FIG. 2 is a flowchart when the foaming data is simply set based on the original image.
Here, “easy setting” is a function that can automatically create foam data corresponding to the type of the original picture when the type of the original picture as the original image is selected.
The display control means 30 displays a screen (FIG. 3) for selecting the type of the original picture as the original image on the display operation unit 200, accepts the selection input selected by the operator (S10), and saves a photograph or the like as a file. Or acquired by a scanner (not shown) (S12).

FIG. 3 is a diagram illustrating an example of a setting screen for easily setting foam data.
The original picture type setting screen 410 has a check box 411 for selecting whether or not to “automatically create by selecting a picture”, and “line drawing” or “oil painting, complicated” where the original picture as the original picture is “crayon, colored pencil, etc.” Check box 412 for selecting whether the image is “a simple picture / photo” or “monotonous picture / photograph such as print / watercolor”, and a check box for selecting whether to “invert” each image 413, 414.
Here, “Automatically select a picture” is set to “Yes”, “Line drawing (crayon, colored pencil, etc.), oil painting, complex picture / photo” is set, “Invert” and “No” are set. Yes.

  Returning to the description of the flowchart of FIG. 2, the stereoscopic image formation control unit 40 (FIG. 1) determines the type of the original picture by determining the setting state of the check box 412 (S <b> 14). If the original picture is centered on the line drawing (line drawing center in S14), the stereoscopic image formation control means 40 determines whether there is a light / dark reversal instruction by determining the setting state of the check box 413 ( S16). When there is an inversion instruction (Yes in S16), the contour extraction image generation means 23 (FIG. 1) extracts the contour of the original picture and generates a contour extraction image (S18). After S18, the contour inverted image generation means 24 inverts the density of the contour extracted image to generate a contour inverted image (S20). On the other hand, if it is determined in S16 that there is no inversion instruction (not in S16), the contour extracted image generating means 23 (FIG. 1) extracts the contour of the original picture and generates a contour extracted image (S22).

4A is a diagram illustrating an example of an original image of a line drawing, FIG. 4B is a diagram illustrating an example of a contour extraction image of a line drawing, and FIG. 4C is an example of an inverted image obtained by inverting the contour extraction image of a line drawing. FIG.
These figures are set to “Line drawing (crayon, colored pencil, etc.), oil painting, complex picture / photograph” by the operator using check boxes 412 and 413 (FIG. 3), and set to “No”. Therefore, the stereoscopic image formation control means 40 (FIG. 1) automatically extracts a contour from the input original picture (FIG. 4A) (S22) and generates a contour extracted image (FIG. 4B). If “Yes” is set using the check box 413 (FIG. 3), the stereoscopic image formation control means 40 automatically inverts the shade (S22) and generates a contour inverted image (FIG. 4C). Note that the contour extraction image in FIG. 4B is foam data with convex black, and the contour inversion image in FIG. 4C is foam data with concave white.

  Returning to the flowchart of FIG. 2 again, if it is determined in S14 that the image is a non-line image that is “monotonous picture / photograph such as print / watercolor” (non-line image in S14), the stereoscopic image formation control means 40, the stereoscopic image formation control means 40 determines whether there is a light / dark reversal instruction by determining the setting state of the check box 414 (S24). When there is an inversion instruction (Yes in S24), the decolorized image generating means 21 (FIG. 1) decolorizes the original picture and generates a decolorized image (S26). After S26, the decolored inverted image generating means 22 inverts the density of the decolored image to generate a decolored inverted image (S28). On the other hand, if it is determined in S24 that there is no inversion instruction (not in S24), the decolorized image generating means 21 decolors the original picture and generates a decolorized image (S30).

5A is a diagram illustrating an example of an original image such as a print, FIG. 5B is a diagram illustrating an example of a decolored image such as a print, and FIG. 5C is a diagram illustrating an example of a decolored inverted image such as a print. is there.
These figures are set by the operator using the check box 412 (FIG. 3) to set “monotonous pictures / photographs such as prints / watercolors”, so that the three-dimensional image formation control means 40 can input the original picture. (FIG. 5A) is automatically decolored (S30), and a decolored image (FIG. 5B) is generated. If “Yes” is set using the check box 414 (FIG. 3), the stereoscopic image formation control unit 40 automatically inverts the shade (S28) and generates a decolored inverted image (FIG. 5C). In addition, FIG. 5A has illustrated in the Kanagawa Hokusai work and the Kanagawa Katsushika beautiful scenery off Kanagawa. Note that the decolored image in FIG. 5B is foam data with white being concave, and the decolored inverted image in FIG. 5C is foam data having convex with black.

  Returning to the flowchart of FIG. 2 again, after S20, S22, S28, and S30, the stereoscopic image formation control unit 40 causes the stereoscopic image forming apparatus 300 to form a three-dimensional image (S32). That is, the three-dimensional image formation control unit 40 causes the two-dimensional image forming apparatus 320 to form any one of the contour inversion image, the contour extraction image, the decolorization inversion image, and the decolorization image on the medium, and to the foaming device 310. Then, the medium on which any of the images is formed is heated to expand a specific portion of the foam layer.

FIG. 6 is a flowchart for setting the foaming data in detail.
Here, the detailed setting refers to setting the contents and parameters of the image processing, repeating the operation of confirming the processed image obtained by image processing of the original image, and confirming the image and parameters.
The control unit 10 performs image input / generation (S50). First, the display control unit 30 displays a screen (not shown) for prompting an image input on the display operation unit 200 (FIG. 1), and acquires a photograph or the like from a file or takes it in with a scanner (not shown). Next, the display control means 30 makes an operator input the mutual contribution rate of decoloring and outline extraction (S55). That is, the display control unit 30 displays the contribution rate setting screen 420a (FIG. 9A) on the display operation unit 200, and causes the operator to set the ratio between decolorization and contour extraction. Next, the preview image generation unit 20 performs image processing such as decoloring, contour extraction, inversion, and image composition on the input color image (original image) (S60).

FIG. 7 is a flowchart of image processing.
First, the decolorized image generating means 21 (FIG. 1) of the preview image generating unit 20 performs a decoloring process (S62). That is, the decolorized image generation means 21 extracts the luminance and brightness of the input color image (original image) and generates a decolorized image. Next, the contour extraction image generation means 23 (FIG. 1) performs contour extraction of the input color image (original image), and generates a contour extraction image (S64).

  Next, the decolored inverted image generation unit 22 inverts the density of the decolored image generated in S62 to generate a decolored inverted image (S66). Further, the contour inversion image generation means 24 inverts the density of the contour extraction image generated in S64 to generate a contour inversion image (S66). Then, the image synthesizing unit 25 (FIG. 1) synthesizes the bleached image and the contour extracted image with the contribution rate set in S55 (S68). In addition, the image synthesis unit 25 synthesizes the decolored image and the contour inverted image, synthesizes the decolored inverted image and the contour extracted image, and synthesizes the decolored inverted image and the contour inverted image. Then, the process proceeds to S70 of FIG. Note that either of the processes of S62 and S64 may be performed first.

  The display control means 30 generates a preview screen 430 (FIG. 9B), and causes the display operation unit 200 to compare and display the plurality of synthesized images synthesized in S68 (S70). That is, the display control unit 30 combines the non-inverted composite image (for example, the contour extracted image 431) obtained by combining the decolored image and the contour extracted image with the first composite image (for example, the contour combined with the decolored image and the contour inverted image). A reverse image 432), a second composite image 433 obtained by combining the decolorized reverse image and the contour extraction image, and a third composite image 434 obtained by combining the decolorized reverse image and the contour reverse image are displayed in comparison.

At this time, the display control means 30 “selects an optimum image from a plurality of images” in advance.
An indication to that effect shall be made. Note that the preview screen 430 includes an “emboss execution” button 435 (FIG. 9B) and an “emboss release” button 445 (FIG. 13), and the display device 100 displays a flag when these buttons are pressed. Is configured to change.

  The preview image generation unit 20 determines the instruction content on the preview screen 430 (S74). That is, the preview image generation unit 20 is any one of the non-inverted composite image (for example, the contour extraction image 431), the first composite image (for example, the contour reverse image 432), the second composite image 433, and the third composite image 434. Image selection, “emboss execution” button 435 (FIG. 9B) pressed, and “emboss release” button 445 (FIG. 13) pressed.

  When any one of the non-inverted composite image, the first composite image, the second composite image, and the third composite image is selected (image selection in S74), the preview image generation unit 20 does not overfoam. Then, the level correction of the selected image (optimum image) is performed (S76), and the level-corrected image data 84 is stored in the nonvolatile storage unit 80 (FIG. 1) (S85). That is, the preview image generation unit 20 prevents the front foaming data and the back foaming data from overlapping and causing excessive foaming. Then, the stereoscopic image formation control means 40 (FIG. 1) forms a stereoscopic image on the medium (S90).

FIG. 8 is a flowchart of stereoscopic image formation.
The stereoscopic image formation control means 40 uses the two-dimensional image forming apparatus 320 to form a black surface image on the medium (S92). As this surface image, for example, a contour extraction image is used. Next, the stereoscopic image formation control unit 40 uses the two-dimensional image forming apparatus 320 to form a black back image on the medium (S94). For example, a contour extraction inverted image, a decolored image, or a decolored inverted image is used as the back surface image. Next, the stereoscopic image formation control unit 40 uses the two-dimensional image forming apparatus 320 to form a color image on the medium (S96). Next, the stereoscopic image formation control means 40 heats the medium using the foaming device 310 to foam the black front image and the back image (S98), and the process ends.

  If the embossing instruction is given in the determination of S74, the embossing processing means 26 (FIG. 1) executes the embossing process (S78), returns to the processing of S70, and the display control means 30 provides a plurality of embossed composites. The image is comparatively displayed on the display operation unit 200 (S70). Then, the preview image generation unit 20 performs level correction of the selected image so as not to overfoam (S76). At this time, the level-corrected image is not an embossed composite image but an image before the embossing process (contour extraction image, contour extraction reverse image, decolorization image, and decolorization reverse image). Then, the level-corrected image data 84 is stored in the nonvolatile storage unit 80 (FIG. 1) (S85). Then, the stereoscopic image formation control unit 40 (FIG. 1) uses the image data 84 to form a stereoscopic image on the medium (S90).

  If the emboss release is instructed in the determination of S74, the emboss processing means 26 (FIG. 1) executes the emboss release (S80), returns to the process of S70, and the display control means 30 displays the plurality of composites for which the emboss has been released. The images are compared and displayed (S70). Then, the preview image generation unit 20 performs level correction of the optimum image selected by the operator so as not to overfoam (S76), and the level-corrected image data 84 is stored in the nonvolatile storage unit 80 (FIG. 1). Save (S85). Then, the stereoscopic image formation control unit 40 (FIG. 1) uses the image data 84 to form a stereoscopic image on the medium (S90).

  FIG. 9 is a diagram illustrating an example of a setting image and a comparison image at a contour extraction contribution rate of 100%. In the contribution rate setting screen 420 (420a) of FIG. 9A, a check box “automatically created” is selected by selecting a picture, the slide bar 425 is set to “contour extraction” at the right end, and contour extraction is performed. The contribution rate is 100%, and the contribution rate of decolorization is 0%.

In particular, since the contribution rate of contour extraction is 100% and the contribution rate of bleaching is 0%, the contour extraction image 431 is displayed on the upper left, and the contour inversion image 432 is displayed on the upper right. Further, the composite image (second composite image 433) of the lower left decolored inverted image and the contour extracted image has no contribution of the decolored inverted image and is the same as the contour extracted image 431, and the lower right decolored inverted image and the contour inverted image. The composite image (third composite image 434) with the image has no contribution of the decolorization inverted image and is the same as the contour inverted image 432.

FIG. 10A shows a contribution rate setting screen 420b, in which a check box “automatically created” is selected by selecting a picture, the slide bar 425 is set to “bleaching” at the left end, and the contribution rate of bleaching. 100% and the contour extraction contribution rate is 0%.

  In FIG. 10B, the combined image of the upper left decolored image and the contour extracted image is the decolored image 436 without the contribution of the contour extracted image, and the combined image 437 of the upper right decolored image and the contour inverted image is The contour inversion image has no contribution and is the same as the decolorization image 436. A composite image of the decolored inverted image and the contour extracted image in the lower left is a decolored inverted image 438 without the contribution of the contour extracted image. The composite image 439 of the lower right decolored inverted image and the contour inverted image has no contribution of the contour inverted image and is the same as the decolored inverted image 438.

  As described above, the display device 100 according to the present embodiment includes a check box 411 for automatically creating foam data “Yes” / “No”, “Line drawing (crayon, colored pencil, etc.), oil painting, complicated picture / photo”. Or a check box 412 for selecting whether it is a monotonous picture / photograph such as a print / watercolor, etc., is displayed on the display / operation unit 200, and the front surface data and the back surface data depending on whether the image is a line image or a print , And using the generated front surface data and back surface data, a stereoscopic image can be formed on the medium placed on the stereoscopic image forming apparatus 300.

  In addition, when the foaming data is not automatically created, the display device 100 according to the present embodiment includes a decolored image 436 and a composite image (non-inverted composite image) of the contour extraction image 431, a decolorized image 436, and a contour reverse image 432. A composite image (first composite image), a composite image (second composite image) of the decolorized reverse image 438 and the contour extraction image 431, and a composite image (third composite image) of the decolorization reverse image 438 and the contour reverse image 432 Can be displayed on the display operation unit 200 for comparison. This comparatively displayed image is a three-dimensional pseudo image, and is a preview image that allows the operator to grasp the touch and appearance before forming a 2.5D stereoscopic image on the medium.

  Further, the preview screen 430 is provided with an “emboss execution” button 435, and the display device 100 can display an emboss preview screen 440 including an emboss image of each image on the display operation unit 200 for comparison. Here, the embossed images shown in FIGS. 13B to 16B have a quality sufficient to grasp the feel and appearance of the formed 2.5D stereoscopic image.

  Then, the display apparatus 100 can cause the stereoscopic image forming apparatus 300 to form a stereoscopic image of an image selected from the displayed plurality of composite images and embossed images. At this time, the image forming the two-dimensional image on the medium is any one of a contour extraction image, a contour extraction inverted image, a decolored image, and a decolorized inverted image, or a combination thereof. The front surface data is preferably a contour extraction image, and the back surface data is preferably any one of a contour extraction inverted image, a decolored image, and a decolorized inverted image, or a combination thereof.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications such as the following are possible.
(1) The stereoscopic image forming system 1000 according to the above embodiment is based on the principle that the contour extraction image is the front foam data, and any one of the contour extraction inverted image, the decolored image, and the decolored inverted image is the back foam data. However, a composite image (non-inverted composite image) obtained by capturing a decolored image in the contour extraction image at a set contribution rate can also be used as the front foam data.

(2) The display device 100 according to the embodiment includes a non-inverted composite image obtained by combining the decolorized image 436 and the contour extracted image 431, a first composite image obtained by combining the decolorized image 436 and the contour inverted image 432, and contour extraction. Four composite images of a second composite image obtained by combining the image 431 and the decolored reverse image 438, a contour composite image 432, and a third composite image obtained by combining the decolorized reverse image 438 are compared and displayed. The display device 100 may compare and display any two or three composite images, instead of the four composite images. At this time, it is preferable that the display device 100 always displays a non-inverted composite image obtained by combining the decolorized image 436 and the contour extraction image 431. (1 composite image, 2nd composite image, 3rd composite image) may be compared and displayed.

  9 to 12 are print image images (images for black printing), and FIGS. 13 to 16 are image images after foaming (images for embossing). The preview image generation unit 20 may cause the display operation unit 200 to display both the print image image and the post-foaming image image on the display screen. The preview image generation unit 20 may also display the original image (color image) together with the print image image or the foamed image image.

  Thereby, the operator can image what kind of three-dimensional image can be formed from the original image. Further, the operator can grasp the feel and appearance of the formed stereoscopic image. In addition, a planar image can be displayed in a three-dimensional manner.

  In the present embodiment, the contribution rate is adjusted in the previous stage (contour extraction, decoloring process), but the contribution rate may be adjusted after synthesis.
