The GPU 62 operates according to a polygon drawing command from the CPU 51, and draws polygons and the like in the frame buffer 63. This GPU 62 can draw up to 360,000 polygons per second. In addition, this GPU 62 has a two-dimensional address space independent of the CPU 51, and the frame buffer 63 is mapped there.

【0020】

The frame buffer 63 is composed of so-called dual-port RAM, and can perform drawing from the GPU 62 or transfer from the main memory 53 and reading for display at the same time. This frame buffer 63 has a capacity of, for example, 1 megabyte, and is treated as a matrix of 16-bit horizontal 1024 pixels and vertical 512 pixels. Any display area in the frame buffer 63 can be output to a video output means 65 such as a display device. In addition to the display area output as video output, the frame buffer 63 is a second area in which a color look-up table (CLUT) referenced by the GPU 62 when drawing polygons or the like is stored. A CLUT area and a texture area, which is a first storage area for storing materials (textures) inserted (mapped) in polygons or the like that are coordinate-converted at the time of drawing and drawn by the GPU 62, are provided. These CLUT areas and texture areas are dynamically changed according to changes in the display area and the like. That is, the frame buffer 63 can execute drawing access to the area being displayed, and can also perform high-speed DMA transfer to and from the main memory 53.

In addition to the above-mentioned flat shading, the GPU 62 also performs Gouraud shading that saves the colors of polygon vertices to determine the color inside the polygon, and texture mapping that attaches the texture stored in the texture area to the polygon. You can do it.

【0022】

When performing these Gouraud shading or texture mapping, the GTE61 can calculate the coordinates of polygons of up to about 500,000 per second.

【0023】

Under the control of the CPU 51, the MDEC64 duplicates the still image or moving image data read from the CD-ROM disc and stored in the main memory 53 and stores it in the main memory 53 again. Specifically, MDEC64 can perform inverse discrete cosine transform (IDCT) operations at high speed, and is a color still image compression standard (so-called JPEG) read from a CD-ROM disk and a storage media video coding standard (so-called MPEG). However, in this example, it is possible to decompress the compressed data (only in-frame compression).

【0024】

Further, the reproduced image data is stored in the frame buffer 63 via the GPU 62, so that the reproduced image data can be used as a background of the image drawn by the GPU 62 described above.

【0025】

The sound system 70 includes a sound reproduction processing processor (SPU) 71 that generates music, sound effects, etc. based on instructions from the CPU 51, and data and sound source data such as voice and music read from a CD-ROM disc. It is provided with, for example, a 512-kilobyte sound buffer 72 for storing data, and a speaker 73 as a sound output means for outputting music, sound effects, etc. generated by the SPU 71.

【0026】

The SPU71 has an ADPCM decoding function that reproduces adaptive differential encoded (ADPCM) audio data using 16-bit audio data as a 4-bit difference signal, and reproduces sound source data stored in the sound buffer 72. It is equipped with a reproduction function for generating sound effects and the like, and a modulation function for modulating and reproducing audio data and the like stored in the sound buffer 72. That is, the SPU71 has functions such as looping and automatic conversion of operation parameters using time as a coefficient, has a built-in ADPCE sound source having a capacity of 24 voices, and operates by operation from the CPU 51. In addition, the SPU71 manages its own address space to which the sound buffer 72 is mapped, transfers ADPCM data from the CPU 51 to the sound buffer 72, and reproduces the data by directly passing key-on / key-off and modulation information.

【0027】

By providing such a function, the sound system 70 can be used as a so-called sampling sound source that generates musical sounds, sound effects, etc. based on the voice data recorded in the sound buffer 72 according to the instruction from the CPU 51. It has become like.

【0028】

The optical disc control unit 80 includes a disk drive device 81 that reproduces programs, data, etc. recorded on an optical disc, which is a CD-ROM disc, and a program that is recorded with, for example, an error correction (ECC) code added. , A decoder 82 that decodes data and the like, and a buffer 83 of, for example, 32 kilobytes that temporarily stores the reproduced data from the disk drive device 81. That is, the optical disk control unit 80 is composed of parts necessary for reading a disk such as the drive device 81 and the decoder 82. Here, data such as CD-DA, CD-ROM, and XA can be supported as a disc format. The decoder 82 also constitutes a part of the sound system 70.

【0029】

In addition to the above-mentioned ADPCM data (ADPCM data of CD-ROM_XA, etc.), the audio data recorded on the disk played by the disk drive device 81 includes so-called PCM data obtained by analog / digital conversion of the audio signal. .. As ADPCM data, for example, audio data recorded by expressing the difference of 16-bit digital data in 4 bits is supplied to the above-mentioned SPU71 after error correction and decoding by the decoder 82, and is digitally / digitally recorded by the SPU71. It is used to drive the speaker 73 after being subjected to processing such as analog conversion. Further, the audio data recorded as PCM data, for example, 16-bit digital data, is decoded by the decoder 82 and then used to drive the speaker 73. The audio output of the decoder 82 once enters the SPU 71, is mixed with the SPU output, and becomes the final audio output via the reverb unit.

【0030】

Further, the communication control unit 90 includes a communication control device 91 that controls communication with the CPU 51 via the main bus B, a controller 92 that inputs instructions from the player, and a memory card 93 that stores game settings and the like. It has.

【0031】

The controller 92 is an interface for transmitting the player's intention to the application, has various keys as described below for inputting an instruction from the player, and follows the instruction from the communication control device 91. The status of is transmitted to the communication control device 91 about 60 times per second by synchronous communication. Then, the communication control device 91 transmits the state of the instruction key of the controller 92 to the CPU 51. The controller 92 has two connectors on the main body, and it is also possible to connect a large number of controllers using a multi-tap. As a result, an instruction from the player is input to the CPU 51, and the CPU 51 performs processing according to the instruction from the player based on the game program or the like being executed.

【0032】

Here, the instruction key of the controller 92 will be described. The controller 92 includes a cross key consisting of a left key L, a right key R, an up key U and a down key D, a first left button 92L1, a second left button 92L2, a first right button 92R1, a second right button 92R2, and a start. It consists of a button 92a, a select button 92b, a first button 92c, a second button 92d, a third button 92e, and a fourth button 92f. The cross key is for the player to give up / down / left / right commands to the CPU 51. The start button 92a is for the player to instruct the CPU 51 to start the operation by the game program data or the like read from the CD-ROM disc and loaded. The select button 92b is for the player to instruct the CPU 51 to make various selections regarding game program data and the like loaded from the CD-ROM disc to the main memory 53.

【0033】

Further, the CPU 51 transmits the stored data to the communication control device 91 when it is necessary to store the settings of the game being executed, the end of the game, or the result in the middle of the game, and the communication control device 91 is concerned with the data. The data from the CPU 51 is stored in the memory card 93. Since this memory card 93 is separated from the main bus B, it can be attached and detached while the power is turned on. As a result, game settings and the like can be stored in a plurality of memory cards 93.

【0034】

The system also has a 16-bit parallel input / output (I / O) port 101 connected to the main bus B and an asynchronous serial input / output (I / O) port 102. Then, it is possible to connect to a peripheral device via the parallel I / O port 101, and to communicate with another video game device or the like via the serial I / O port 102. Can be done.

【0035】

By the way, the main memory 53 needs to transfer a large amount of image data at high speed between the GPU 62, MDEC 64, decoder 82, etc. when reading a program, displaying an image, drawing, or the like. Therefore, in this image processing system, as described above, data is directly transferred between the main memory 53, the GPU 62, the MDEC 64, the decoder 82, etc. by the control from the peripheral device controller 52 without going through the CPU 51, so-called DMA transfer. Can be done. As a result, the load on the CPU 51 due to data transfer can be reduced, and high-speed data transfer can be performed.

【0036】

In this video game device, when the power is turned on, the CPU 51 executes the operating system stored in the ROM 54. By executing this operating system, the CPU 51 initializes the entire device such as operation check, and then controls the optical disk control unit 80 to execute a program such as a game recorded on the optical disk. By executing a program such as this game, the CPU 51 controls the graphic system 60, the sound system 70, etc. in response to the input from the player to control the display of images, sound effects, and the generation of musical sounds. There is.

【0037】

Next, the display on the display in the image processing system of this example will be described. The GPU 62 displays the contents of an arbitrary rectangular area in the frame buffer 63 as it is on a display such as a CRT of the video output means 65. This area is hereinafter referred to as a display area. The size of the rectangular area can be selected according to the setting mode. For example, in mode 0, 256 (H) x 240 (V) (non-interlaced), and in mode 9, 384 (H) x 480 (V). (Interlaced). That is, the display start position and the display end position can be specified independently in the horizontal direction and the vertical direction, respectively. The relationship between the values that can be specified for each coordinate and the screen mode is, for example, the specified range of horizontal coordinates is mode 0 and 4, 0 to 276 (horizontal display start position coordinates), 4 to 280 (horizontal display). (End position coordinates), 0 to 396 (horizontal display start position coordinates), 4 to 400 (vertical display end position coordinates) in modes 8 and 9. The specified range of vertical coordinates is 0 to 240 (vertical display start position coordinates) in modes 0 to 3 and 8, and 4 to 484 (vertical display end position coordinates) in modes 4 to 7 and 9. .. Here, it is necessary to set the horizontal start and end position coordinates to be a multiple of 4. Therefore, the minimum screen size is 4 pixels horizontally, 2 pixels vertically (at the time of non-interlacing), or 4 pixels (at the time of interlacing).

【0038】

In addition, the GPU 62 supports two modes related to the number of display colors: 16-bit direct mode (32768 colors) and 24-bit direct mode (full color). The above 16-bit direct mode (hereinafter referred to as 16-bit mode) is a 32768 color display mode. In this 16-bit mode, the number of display colors is limited compared to the 24-bit direct mode (hereinafter referred to as the 24-bit mode), but the color calculation inside the GPU 62 at the time of drawing is performed in 24-bit, and the gradation is changed. Since it is also equipped with a so-called dither function that can be pseudo-high, pseudo full-color (24-bit color) display is possible. The 24-bit mode is a mode for displaying 26777216 colors (full color). However, only the image data transferred into the frame buffer 63 can be displayed (bitmap display), and the drawing function of the GPU 62 cannot be executed. Here, the bit length of 1 pixel is 24 bits, but the coordinates and display position values on the frame buffer 63 need to be specified based on 16 bits. That is, the 640 × 480 24-bit image data is treated as 960 × 480 in the frame buffer 63. Further, the horizontal display end position coordinates need to be set to be a multiple of 8, and therefore, the minimum screen size in this 24-bit mode is 8 horizontal × 2 vertical pixels.

【0039】

In addition, the GPU 62 is equipped with the following drawing functions. First, for polygons or sprites of 1 x 1 dot to 256 x 256 dots, 4-bit CLUT (4-bit mode, 16 colors / polygon, sprite) or 8-bit CLUT (8-bit mode, 256 colors / polygon, sprite) , 16-bit CLUT (16-bit mode, 32768 colors / polygon, sprite), etc., and a polygon or sprite drawing function that can draw, and the coordinates of each vertex of the polygon or sprite on the screen are specified for drawing, and the polygon Flat shading that fills the inside of sprites with the same color, gourd shading that specifies different colors for each vertex and gradations inside, texture patterns that are two-dimensional image data on the surface of polygons and sprites (especially sprite patterns for sprites) A polygon drawing function that easily pastes textures, a straight line drawing function that allows gradation, an image transfer function such as transfer from the CPU 51 to the frame buffer 63, and other functions such as each pixel. The function to take the average of and make it semi-transparent, that is, the function called α blending function because the pixel data of each pixel is mixed at a predetermined ratio α, the dither function to add noise to the color boundary and blur it, and beyond the drawing area. There is a drawing clipping function that does not display the drawn part, an offset specification function that moves the drawing origin according to the drawing area, and so on.

【0040】

In addition, the coordinate system for drawing is in units of signed 11 bits, and each of X and Y takes a value of -1024 to +1023. Moreover, since the size of the frame buffer 63 in this example is 1024 × 512, the protruding part is folded back. The origin of the drawing coordinates can be freely changed in the frame buffer 63 by the function of arbitrarily setting the offset value of the coordinate values. Further, drawing is performed only on an arbitrary rectangular area in the frame buffer 63 by the drawing clipping function. Furthermore, the CPU62 supports textures of up to 256 x 256 dots, and the vertical and horizontal values can be set freely.

【0041】

The image data (texture pattern or sprite pattern) to be attached to the polygon or sprite is arranged in the non-display area of the frame buffer 63. As for the texture pattern or sprite pattern, 256 × 256 pixels can be regarded as one page, and as many sheets as the memory allows can be placed on the frame buffer 63, and this 256 × 256 area is called a texture page. The location of one texture page is determined by specifying the page number in the parameter for specifying the position (address) of the texture page of the drawing command.

【0042】

The texture pattern or sprite pattern has three types of color modes: 4-bit CLUT (4-bit mode), 8-bit CLUT (8-bit mode), and 16-bit CLUT (16-bit mode). CLUT is used in the color modes of 4-bit CLUT and 8-bit CLUT. This CLUT is a frame buffer 63 in which 16 to 256 R, G, and B values of the three primary colors representing the colors to be finally displayed are arranged. Each R, G, B value is numbered in order from the left on the frame buffer 63, and the texture pattern or sprite pattern represents the color of each pixel by this number. In addition, the CLUT can be selected in units of polygons or sprites, and it is possible to have an independent CLUT for all polygons or sprites. The storage position of the CLUT in the frame buffer 63 is determined by specifying the leftmost coordinate of the CLUT to be used in the parameter for specifying the position (address) of the CLUT in the drawing command.

【0043】

In addition, the GPU 62 uses a method called frame double buffering as a method for displaying moving images. This frame double buffering is to prepare two rectangular areas on the frame buffer 63, display the other side while drawing in one area, and exchange the two areas with each other when drawing is completed. Is. As a result, it is possible to avoid displaying the state of rewriting. The buffer switching operation is performed within the vertical blanking interval. Further, in the GPU 62, since the rectangular area to be drawn and the origin of the coordinate system can be freely set, it is possible to realize a plurality of buffers by moving these two.

【0044】

The drawing instruction is in packet format. In this example, there are a format directly specified by the CPU 51 and a format directly specified by the dedicated hardware. In particular, in the format directly specified by the dedicated hardware, a packet configuration is used in which the instruction format used by the CPU 51 is tagged with the number of words of the instruction and a pointer to the next instruction. As a result, a plurality of instruction sequences that are not placed in a continuous area on the frame buffer 63 can be connected and executed at one time. In this case, the transfer of drawing instructions is performed by dedicated hardware, and CPU51 is not involved at all. The parameters that can be included in the drawing instruction are as follows. CDDE: Command code calling option R, G, B: Luminance value shared by all vertices Rn, Bn, Gn: Luminance value of vertex n Xn, Yn: Two-dimensional coordinates of vertex n in drawing space Un, Vn: Two-dimensional coordinates of points on the texture source space corresponding to vertex n CBA (CLUT BASE ADDRESS): CLUT start address TSB (TEXTURE SOURCE BASE): Additional information such as texture page top address and texture type [0045]

For example, the triangle drawing command (command code 1h) gives vertex information as an argument after the command code including options. Good for options, different arguments and format. As a parameter, IIP: Type of brightness value SIZ: Rectangle area size CNT: Vertex used TME: With or without texture mapping ABE: With or without translucent processing TGE: Presence or absence of multiplication of texture pattern and brightness value [0046]

For example, when IIP is 0, a triangle is drawn (flat shading) with one type of brightness value (R, G, B). Also, for example, when CNT is 0, one triangle is drawn with the three vertices following the command, and when it is 1, a connected triangle is drawn with the four vertices following the command, that is, a quadrangle is drawn. When TME is 0, the curly texture mapping is turned off, and when it is 1, texture mapping is turned on. When ABE is 0, translucent processing is turned off, and when ABE is 1, translucent processing is turned on. TGE is valid only when TME, and displays by multiplying the texture pattern of 0 and the brightness value, and draws only the texture pattern when it is 1.

【0047】

The straight line drawing command (command code = 2h) gives single point information as a command argument after the command code including options. The number and format of arguments differ depending on the option. For example, when the IIP is 0, the pixel is drawn with the specified luminance value, and when it is 1, the luminance values of the two vertices are linearly interpolated by the displacement in the long axis direction of the line segment. When CNT is 0, one straight line is drawn at the two endpoints following the command, and when it is 1, a connecting straight line is drawn. When ABE is 0, translucent processing is turned off, and when ABE is 1, translucent processing is turned on. When drawing a concatenated line, a terminal code indicating the end of the command is required at the end.

In the sprite drawing command (command code = 3h), after the command code (including options), the brightness information, the left lower end point of the rectangular area, the upper left end point of the texture source space, and the width and height of the rectangular area are given as command arguments. The number of arguments and format differ depending on the option. Also, since the sprite drawing command processes two pixels at the same time, the two-dimensional coordinate Un of the point on the texture source space corresponding to the vertex n must be specified as an even number.

【0049】

That is, the lower 1 bit has no meaning. When TME is 0, texture mapping is turned off, and when TME is 1, texture mapping is turned on. When ABE is 0, translucent processing is turned off, and when ABE is 1, translucent processing is turned on. When TGE (valid only when TME) is 0, the texture pattern (sprite pattern in this case) is multiplied by a certain brightness value and drawn, and when it is 1, only the texture pattern is drawn. When SIZ is 00, it is specified in H and 2 fields, when it is 01, it is specified in 1x1, when it is 10, it is specified in 8x8, and when it is 11, it is specified in 16x16.

【0050】

By the way, in the video game program recorded on the CD-ROM disc 81 in the present embodiment, the player selects a favorite character, feeds this character, disciplines, etc., and virtually nurtures this character. It is a program for executing a training game. The applicant has already applied for a game in which a dog is used as a character and the dog is virtually raised (see Japanese Patent Application No. 10-284513). The video game program in this embodiment is applied to the training game proposed in Japanese Patent Application No. 10-284513.

【0051】

In addition, in the training game of the present embodiment, the dog, which is the character selected by the player, can be virtually dressed (changed) or accessories such as ribbons can be virtually worn. The clothes or accessories worn on the dog are reflected in the display image of the character in the state of being trained.

【0052】

These clothes or accessory wearing operations are performed during the dress-up mode. The dress-up mode is executed by selecting the dress-up mode on the mode selection screen (not shown) in which various modes can be selected at the start of the training game of the present embodiment.

【0053】

When the dress-up mode is selected, the dress-up screen as shown in Fig. 2 is displayed first. A character image D showing the dog, which is the character selected by the player, is displayed in the center of the dress-up screen, and a pattern image P showing the types and patterns (color patterns) of clothes or accessories that the player can select on the right side. (In the illustrated example, a pattern image of an accessory) is displayed in multiple types. The operation of wearing clothes or wearing accessories can be switched by the player pressing the "accessory" button B1 or the "replacement" button B2 displayed at the top of the dress-up screen.

【0054】

When the player moves the pointer of the illustration on the pattern image P corresponding to the favorite clothes or accessories among the pattern images P of the clothes or accessories displayed on the dress-up screen and performs the selection operation, the dress-up is performed. The selection operation is reflected in the character image D on the screen. As an example, as shown in FIG. 3, when the pattern image P1 corresponding to the horizontal striped clothes is selected by the player, the character image D1 in the state of wearing the horizontal striped clothes is displayed on the dress-up screen. The pointer movement and selection operations are performed by the player operating the controller 92 according to a predetermined procedure.

【0055】

In the case of accessories, for example, the ribbon can be attached to the right ear, left ear, or tail, and the attachment location is not uniform. Therefore, as shown in Fig. 2, the attachment location is set after the pattern is selected. There is a "basho" button B3 to identify, and each time you press this "basho" button B3, the character image D in a state where the accessory corresponding to the selected pattern can be attached to any of the places where it can be attached. Is displayed, and by pressing the "Basho" button B3 in sequence, the accessory is virtually attached to the player's favorite position.

【0056】

The data for displaying the pattern image P and the data for displaying the clothes and accessories actually worn on the character are stored in the CD-ROM disk 81 together with the program data, and the work is required as needed. It is read into RAM53.

【0057】

Normally, a default color is set for the clothes or accessories and the corresponding pattern image P, and the clothes or accessories of the default colors are attached to the character. More specifically, the garment or accessory is usually composed of a two-color pattern, and the data for displaying the garment or the accessory and the data for displaying the corresponding pattern image P are provided. Includes data indicating the pattern of clothing or accessories and color designation data assigned to the pattern. In the present embodiment, the clothes or accessories are displayed as textures mapped to the polygons of the model indicating the character, so the pattern data is the texture pattern data, and the color specification data is the color lookup table assigned to the pattern ( Corresponds to the number data of CLUT). Since a predetermined color is already assigned to the CLUT when the game is started, the default color means a color based on the CLUT assigned when the game is started.

【0058】

Although a clear illustration is omitted, some clothes or accessories prepared in advance use two or more colors such as gradation, but even in this case, two colors are used. If the color of is specified, the remaining colors can be calculated uniquely.

【0059】

Then, in the present embodiment, the player can further specify and change the color of the clothes or accessories selected by the player. In this embodiment, two modes are prepared for color designation and change. One is a simple setting mode in which an arbitrary color combination is selected from two preset color combinations, and the other is a detailed setting mode in which RGB values are directly specified for each of the two colors.

【0060】

As shown in Figure 3, when the player specifies the clothes or accessories to wear, the "color" button B4 is displayed on the dress-up screen, and the player presses this "color" button B4 to switch to the simple setting mode. It is selected and executed, and the simple setting mode screen shown in Fig. 4 is displayed.

【0061】

In the simple setting mode screen shown in FIG. 4, a plurality of candidate display images N (10 in the illustrated example) showing candidates for two color combinations are displayed on the right side of the screen. Then, when the player selects one of the candidate display images N, the color data corresponding to the selected candidate display image N is written in the CLUT at the number specified by the color specification data of the clothes or accessories. As a result, the character image with the clothes or accessories based on the selected color combination is displayed on the simple setting mode screen (since it has not been selected in the illustrated example, the character image D1 similar to that in FIG. 3 is displayed. Is displayed).

【0062】

Next, in the simple setting mode screen of FIG. 4, when the "palette" button B5 displayed at the lower right of the screen is pressed, the detailed setting mode is selected and executed, and the detailed setting mode screen shown in FIGS. 5 and 6 is displayed. Is displayed.

【0063】

In the detailed setting mode screen shown in FIGS. 5 and 6, a color specification image for directly specifying two colors is displayed on the right side of the screen. The color designation image has a color designation value display image CV indicating each of the R value, G value, and B value when each color is expressed by RGB values, and the player operates the color designation value display image CV to 32 each. RGB values can be specified directly in stages. Then, the color data consisting of the specified RGB values is written in the part of the CLUT with the number specified in the color specification data of the clothes or accessories. As a result, the character image with the clothes or accessories based on the selected color combination attached is displayed on the detailed setting mode screen. In FIG. 5, the color of the dark stripe portion of the horizontal stripe pattern is specified, and in FIG. 6, the color of the light stripe portion of the horizontal stripe pattern is specified.

【0064】

In the simple setting mode, candidates for a combination of two colors are determined in advance, and even if the pattern of clothes or accessories consists of two or more colors, colors other than the two colors displayed as candidates are also displayed. Although it is predetermined (it is not displayed), in the advanced setting mode, the player directly specifies the color, so if the pattern of clothes or accessories consists of two or more colors, it is specified by the program side. Create a color other than the two colors. Specifically, as shown in FIG. 7, from the RGB values of the two colors specified by the player, the RGB values of the intermediate colors required for forming the gradation based on the amount of change are calculated. The example shown in Fig. 7 is an example of forming a gradation pattern in which the RGB values change linearly, but even if it is not the case, it is not possible to calculate other colors based on the two colors specified by the player. it can.

【0065】

The clothes or accessories specified by the player as described above, and the colors of the clothes or accessories are reflected in the character display image on the actual game screen. FIG. 8 shows the game screen when the wearing of clothes or accessories is not specified, and FIG. 9 shows the game screen after specifying the wearing of clothes or accessories. In Fig. 9, it can be understood that the dog, which is the character, is wearing clothes.

【0066】
