JP 2004-334550 A

  In the case of a high-function image processing apparatus such as a PC, the technique disclosed in Patent Document 1 can be adopted. Image processing may not be performed.

  Further, when the board of the gaming machine is a two-dimensional image processing board, the board does not have an image processing function in units of subpixels. When performing stereoscopic image processing in units of sub-pixels in such a gaming machine, the gaming machine stores image data for each viewpoint for stereoscopic viewing and synthesizes the image data when performing stereoscopic viewing. A method can be considered.

  However, since it is necessary to provide image data for each viewpoint for each production pattern, a large storage capacity is required to store the image data. In particular, in the case of gaming machines, it is necessary to perform various effects and cost reduction is required, and mounting a memory having a large storage capacity is difficult to apply practically.

  In addition, when the image processing apparatus uses a process of superimposing a partially transparent image in units of pixels, which is generally used as a means for synthesizing images, a contradiction occurs in the color of the edge of the image. . This is because sub-pixel processing is required for stereoscopic viewing, whereas the image processing substrate does not have a sub-pixel processing function. However, providing an image processing apparatus with a sub-pixel processing function increases costs, and is practically difficult to apply.

Based on the sprite image data for each viewpoint and the stereoscopic background image data, the stereoscopic image data generating unit is configured to generate stereoscopic image data.

An information storage medium according to the present invention is a computer-readable information storage medium,
The above program is stored.

  According to the present invention, an image generation system for a gaming machine or the like can sequentially generate sprite image data for each viewpoint and stereoscopic background image data by using mask image data that can be processed in units of sub-pixels. it can. As a result, the image generation system for gaming machines and the like do not need to provide image data for each viewpoint in advance for each production pattern, so that the parallax barrier method of stereoscopic vision based on image processing in units of subpixels with a smaller storage capacity can be achieved. Can be realized.

The gaming machine image generation system and the computer include:
A background mask image data generation unit that generates the background mask image data based on the sprite image data and the sprite mask image data may be included.

  According to this, the image generation system for gaming machines and the like can sequentially generate the background mask image data, and there is no need to store the background mask image data in advance. Thereby, the image generation system for gaming machines and the like can realize a stereoscopic view of a parallax barrier method by image processing in units of subpixels with a smaller storage capacity.

  Further, the stereoscopic background image data generation unit, when the target viewpoint is the n-th viewpoint (n is an integer of 2 or more), the stereoscopic image data at the time of processing of the n-1 viewpoint. May be used as the sprite background image data.

  According to this, the image generation system for gaming machines and the like can generate final stereoscopic image data by sequentially superimposing stereoscopic image data from the first viewpoint to the nth viewpoint. Therefore, appropriate stereoscopic image data can be generated with a small processing load.

  Further, a two-dimensional image processing board including the sprite image data generation unit for each viewpoint, the stereoscopic background image data generation unit, and the stereoscopic image data generation unit may be included.

  According to this, even when an image generation system for gaming machines uses a cheap two-dimensional image processing board having a processing capacity lower than that of a three-dimensional image processing board, the sub-pixel unit has a smaller storage capacity. It is possible to realize parallax barrier stereoscopic viewing by image processing.

  Further, the sub-pixel may be a pixel indicating any one of R, G, and B color information.

  According to this, the image generation system for gaming machines and the like can generate stereoscopic image data that can be processed in units of R, G, and B subpixels.

A sprite image data, based on the sprite mask image data, and is configured to include a background mask image data generation unit 118 for generating a background mask image data, and a storage unit 119.

  These units are mounted on a two-dimensional image processing board 110 having a two-dimensional image processing function. The two-dimensional image processing board 110 (computer) may implement the functions of these units by reading a program from the information storage medium 200.

  As the information storage medium 200, for example, a CD-ROM, DVD-ROM, IC card, ROM, RAM, memory card, HDD, or other storage medium using laser or magnetism can be applied. Further, the method of reading the program from the information storage medium 200 may be a contact type or a non-contact type. The two-dimensional image processing board 110 may implement the functions of these units by downloading a program via a network.

  More specifically, the gaming machine image generation system 100 is incorporated in a gaming machine.

  FIG. 2 is a hardware block diagram of the gaming machine 300 in the present embodiment.

  For example, the gaming machine 300 (for example, a pachinko machine, a slot machine, etc.) includes a CPU 301, a CPU work RAM 302, a program ROM 303, a VDP (Video Display Processor) 304, a VRAM 305, an image ROM 306, and a liquid crystal panel 307. It is comprised including. Although not shown, the gaming machine 300 is configured to include hardware for operation by the player.

  For example, the functions of the sprite image data generation unit 112 for each viewpoint, the background image data generation unit for stereoscopic vision 114, the image data generation unit for stereoscopic vision 116, and the background mask image data generation unit 118 can be implemented by the VDP 304, and the storage unit 119 This function can be implemented by the VRAM 305 and the image ROM 306. Also, some of the functions of the sprite image data generation unit 112 for each viewpoint may be implemented by the CPU 301, and some of the functions of the storage unit 119 may be implemented by the CPU work RAM 302 and the program ROM 303.

  The liquid crystal panel 307 is a stereoscopic liquid crystal panel provided with a parallax barrier in units of subpixels. Here, the stereoscopic view in the case of 2 viewpoints and the case of 4 viewpoints will be described.

  FIG. 9 is a schematic diagram of a stereoscopic view of a parallax barrier system with two viewpoints. FIG. 10 is a schematic diagram of stereoscopic vision using a four-view parallax barrier system.

  In the case of two viewpoints, an opaque parallax barrier 620 is provided in front of the LCD 630, and the observer observes the right-eye pixel R through the lens filter 610 at the right-eye viewpoint 1 (PR), and the left-eye viewpoint. By observing the pixel L for the left eye at 2 (PL), stereoscopic vision is realized. Note that the parallax barrier 620 may be provided behind the LCD 620.

  In the case of four viewpoints, as in the case of two viewpoints, an opaque parallax barrier 720 is provided in front of the LCD 730 so that the viewer can view viewpoints 1 (P1), 2 (P2), and 2 through the lens filter 710. Stereoscopic viewing is realized by observing any one of the pixels 1 to 4 from two adjacent viewpoints of the viewpoint 3 (P3) and the viewpoint 4 (P4). Note that the parallax barrier 720 may be provided behind the LCD 720.

(Description of the flow of image processing)
Next, the flow of image processing in stereoscopic viewing of two viewpoints by each unit such as the sprite image data generation unit 112 for each viewpoint will be described.

  FIG. 3 is a flowchart showing the flow of image processing in the present embodiment. FIG. 4A is a diagram illustrating the entire image 400 including the stereoscopic image 410 in the present embodiment, and FIG. 4B illustrates the sprite background image 411 for the viewpoint 1 in the present embodiment. FIG. 4C is a diagram showing a sprite background image 412 for viewpoint 2 in the present embodiment, and FIG. 4D is a diagram showing a stereoscopic image 413 in the present embodiment. 5A is a diagram showing the pixel 420 in the case of two viewpoints, FIG. 5B is a diagram showing the sprite image data 431 in the case of two viewpoints, and FIG. FIG. 5D is a diagram illustrating sprite mask image data 432 in the case of two viewpoints, and FIG. 5D is a diagram illustrating sprite image data 433 for each viewpoint in the case of two viewpoints. 6A is a diagram showing sprite background image data in the case of two viewpoints, and FIG. 6B is a diagram showing background mask image data in the case of two viewpoints. ) Is a diagram showing stereoscopic background image data in the case of two viewpoints, and FIG. 6D is a diagram showing stereoscopic image data in the case of two viewpoints.

  As shown in FIG. 4A, the entire image 400 is configured so that only the numeral “7” is stereoscopically viewed. In addition, the gaming machine image generation system 100 performs the stereoscopic image processing only on the part of the stereoscopic image 410 and generates the entire image 400 by synthesizing the part and the part other than the stereoscopic image 410.

  Further, the liquid crystal panel 307 is formed with a parallax barrier (a hatched portion in FIG. 5A) in units of subpixels in an oblique direction. That is, in this embodiment, a step-like parallax barrier method is adopted, but a general parallax barrier method (a method in which a parallax barrier is formed in the vertical direction) may be adopted. Further, as shown in FIG. 5A, one pixel 420 is formed by three effective sub-pixels. Further, the sub-pixels constituting one pixel 420 are pixels that indicate any color information of R, G, and B. The color information is represented by 8 bits, and is represented by a numerical value from 0 to 255 (so-called RGB value or the like).

  First, the background mask image data generation unit 118 generates sprite white mask image data based on the sprite image data 431 stored in the storage unit 119, and subtracts the sprite mask image data 432 from the sprite white mask image data (RGB) The background mask image data 442 is generated by subtracting the numerical value in units of pixels) (step S1).

  Note that the viewpoint 1 (left eye) sprite image is an image of the portion “7” on the left side shown in FIG. 4A, and the viewpoint 2 (right eye) sprite image is “7” on the right side shown in FIG. 4A. It is an image of a portion of “”. In this sprite image, the portion other than “7” is represented in black. The background image is an image of the stereoscopic image 410 other than the two “7” background portions and the two “7” portions.

  For example, as shown in FIG. 5B, the sprite image data 431 in the pixel 420 is “100” in the upper left, “50” in the upper middle, “70” in the upper right, “10” in the lower left, and “10” in the lower left. In the case where the data is “50” and the lower right is “20”, the background mask image data generation unit 118 replaces the portion having one or more numerical values in the sprite image data 431 with “255”. Mask image data is generated. That is, the sprite white mask image is an image in which a portion of the sprite image (the number portion of “7”) is expressed in white and a portion other than the portion is expressed in black.

  As shown in FIG. 5C, the sprite mask image data 432 for viewpoint 1 in the pixel 420 to be processed is “0” in the upper left, “255” in the upper middle, “0” in the upper right, and “0” in the lower left. The data is “255”, the lower middle is “0”, and the lower right is “255”.

  Therefore, the background mask image data generation unit 118 subtracts the sprite mask image data 432 from the sprite white mask image data (in this case, all numerical values are 255), thereby obtaining the background mask image data 442 shown in FIG. Can be generated. The background mask image data 442 in this case is “255” in the upper left, “0” in the upper middle, “255” in the upper right, “0” in the lower left, “255” in the lower middle, and “0” in the lower right. It is data of.

  Then, the sprite image data generation unit 112 for each viewpoint generates the sprite image data 433 for each viewpoint for the viewpoint 1 by subtracting the sprite mask image data 432 from the sprite image data 431 (step S2). In this case, as shown in FIG. 5D, the sprite image data for each viewpoint 433 is “100” in the upper left, “0” in the upper middle, “70” in the upper right, “0” in the lower left, and the lower middle. Is “50” and the lower right is “0”.

  Then, the stereoscopic background image data generation unit 114 subtracts the background mask image data 442 shown in FIG. 6B from the sprite background image data 441 shown in FIG. 443 is generated (step S3).

  In this case, the sprite background image data 441 is data in which the numerical values of all the color information are “50”. For example, as shown in FIG. 4B, the sprite background image 411 for viewpoint 1 is a single gray color. It is a one-color image.

  In this case, as shown in FIG. 6C, the stereoscopic background image data 443 is “0” in the upper left, “50” in the upper middle, “0” in the upper right, “50” in the lower left, and the middle. The lower data is “0” and the lower right data is “50”.

  Further, the stereoscopic image data generation unit 116 adds the data obtained by adding the stereoscopic background image data 443 obtained in step S3 and the viewpoint-specific sprite image data 433 obtained in step S2 to a new sprite background image. Apply as data (step S4). That is, as illustrated in FIG. 4C, the sprite background image 412 for viewpoint 2 is an image in a state where the sprite image for viewpoint 1 and the background image are combined.

  The gaming machine image generation system 100 executes the above processing steps S1 to S4 until the processing of all viewpoints is completed (step S5).

  When the processing for all viewpoints is completed, the stereoscopic image data generation unit 116 applies the new sprite background image data obtained in step S4 as the stereoscopic image data 450 (step S6).

  The gaming machine image generation system 100 generates a stereoscopic image 410 based on the stereoscopic image data 450, and combines the stereoscopic image 410 and a background image other than the stereoscopic image 410, and displays the entire image 400 on the liquid crystal panel 307. Is displayed using (Step S7).

  As described above, according to the present embodiment, the gaming machine image generation system 100 uses the mask image data (sprite mask image data 432 and background mask image data 442) that can be processed in units of subpixels. The sprite image data for each viewpoint 433 and the background image data for stereoscopic vision 443 can be sequentially generated.

  In addition, according to the present embodiment, the gaming machine image generation system 100 can solve the contradiction in the color of the edge of the image, which has been a problem when using a display substrate that can only process in units of pixels. . In the conventional method, when processing is performed in units of pixels, even when it is necessary to change only G among RGB values at the end, for example, the value of RB is also changed simultaneously with G. For this reason, inconsistency has occurred in pixel-by-pixel processing, but according to the present embodiment, the gaming machine image generation system 100 can correctly perform processing in all portions including the end portion.

  Further, the gaming machine image generation system 100 can sequentially generate the background mask image data 442, and the background mask image data 442 need not be stored in the image ROM 306 in advance. Of course, the gaming machine image generation system 100 may store the background mask image data 442 in the image ROM 306 in advance.

  Thus, the gaming machine image generation system 100 can realize parallax barrier stereoscopic viewing by image processing in units of sub-pixels with a smaller storage capacity.

  In addition, the gaming machine image generation system 100 sequentially superimposes stereoscopic image data (new sprite background image data) from the first viewpoint to the second viewpoint, thereby obtaining final stereoscopic image data 450. Therefore, appropriate stereoscopic image data 450 can be generated with a small processing load.

  In addition, the gaming machine image generation system 100 performs the processing related to the sprite only on the portion where the stereoscopic view is performed (stereoscopic image 410) instead of the entire image 400, thereby reducing the image processing load and reducing the stereoscopic view. Can be realized.

  Further, according to the present embodiment, the image generation system 100 for gaming machines can use the two-dimensional image processing board 110 that consumes less power and generates less heat than the three-dimensional image processing board. Energy saving can be realized compared to the case of using a substrate.

  Furthermore, according to the present embodiment, the gaming machine 300 increases the capacity of the image ROM 306 even when using the two-dimensional image processing board 110 and the liquid crystal panel 307 provided with the parallax barrier in units of subpixels. Therefore, appropriate stereoscopic vision can be realized.

  In addition, this invention is not limited to the Example mentioned above, A various deformation | transformation is possible.

  For example, the number of viewpoints for performing stereoscopic viewing is not limited to 2, and the gaming machine image generation system 100 can set any integer viewpoint of 3 or more. Here, data in the case of four viewpoints will be described.

  FIG. 7A is a diagram showing sprite image data 531 in the case of four viewpoints, and FIG. 7B is a diagram showing sprite mask image data 532 in the case of four viewpoints. FIG. 10 is a diagram illustrating viewpoint-specific sprite image data 533 in the case of four viewpoints. 8A is a diagram showing sprite background image data 541 in the case of four viewpoints, and FIG. 7B is a diagram showing background mask image data 542 in the case of four viewpoints. FIG. 7C is a diagram illustrating stereoscopic background image data 543 for four viewpoints, and FIG. 7D is a diagram illustrating stereoscopic image data 550 for four viewpoints.

  In this embodiment, it is assumed that one pixel is represented by three subpixels (one smallest rectangle). In the sprite image data 531 of FIG. 7A, “r”, “g”, and “b” each contain one or more numerical values of R, G, and B, and “0” has an RGB value of 0. Indicates that there is.

  In the sprite mask image data 532 for the viewpoint 1 in this case, as shown in FIG. 7B, numerical values of “0” are arranged in a staircase pattern, and portions other than “0” are “255 (X in the figure). It shows.) ” In this embodiment, a stepped parallax barrier method is adopted as a four-view stereoscopic display method.

  By subtracting the sprite mask image data 532 from the sprite image data 531, the sprite image data 533 for each viewpoint for the viewpoint 1 is generated.

  In the sprite background image data 541 in FIG. 8A, “R”, “G”, and “B” indicate that one or more numerical values of R, G, and B are included, respectively.

  The background mask image data 542 becomes the data shown in FIG. 8B by the method of step S1 described above.

  By subtracting the background mask image data 542 from the sprite background image data 541, stereoscopic background image data 543 shown in FIG. 8C is generated.

  The viewpoint-specific sprite image data 533 and the stereoscopic background image data 543 are added to generate stereoscopic image data 550 shown in FIG. 8D.

  As described above, the gaming machine image generation system 100 can realize stereoscopic viewing by the same image processing as in the case of two viewpoints even when performing stereoscopic viewing with four viewpoints.

  The background mask image data generation unit 118 is not an essential component, and background mask image data 442 and 542 are stored in the image ROM 306 in advance, and the stereoscopic background image data generation unit 114 stores the background mask in the image ROM 306. Stereoscopic background image data 443 and 543 may be generated using the image data 442 and 542.

  Further, the order of the processes is not limited to the example shown in FIG. 3, and the gaming machine image generation system 100 may execute the process of step S2 after executing the process of step S3, for example.

  In the above-described embodiment, the gaming machine image generation system 100 subtracts data (numerical values), but it is also possible to obtain the same result as when subtracted by performing bit inversion or the like of the data. The technique for implementing the present invention is not limited to subtraction.
