The image data and the audio data are read, and the read game program and data are supplied to the decoder 14.

The decoder 14 has a CD-ROM driver 1
ECC (Error Correction)
(n Code), and supplies the error-corrected data to the main memory 5 or the audio processor 12.

The memory 20 is a card type memory,
In order to maintain the state at the time of the game interruption, various parameters at the time of the game interruption are stored. Controller 21
Is a cross key 21g integrating a left key, a right key, an up key, and a down key, a left button 21L and a right button 21R.
, Start button 21a, select button 21b
And first to fourth buttons 21c to 21f. Here, the cross key 21g indicates that the game player
It is a key for giving commands indicating up, down, left and right to U1.

The outline of the operation of the video game machine described above is as follows. That is, in a case where the CD-ROM 23 is loaded in the main body of the apparatus, when the power of the main body is turned on, the CPU 1 sends the CD-ROM driver 16 to the CD-ROM driver 16 based on the operating system recorded in the ROM 6. -Instruct to read image data, audio data, a game program (including data used when executing the program) and the like from the ROM 23. As a result, the CD-ROM driver 16

The image data subjected to the error correction processing by the decoder 14 is supplied to the expansion circuit 7 via the bus 2. The expansion circuit 7 performs expansion processing on the supplied image data, and supplies the image data to the drawing processor 10 via the bus 2. Drawing processing processor 10
Writes the supplied image data into the non-display area of the buffer 11. The audio data on which the error correction processing has been performed by the decoder 14 is supplied to the main memory 5 or the audio processor 12 via the bus 2 and written into the main memory 5 or the buffer 13. The game program that has been subjected to the error correction processing by the decoder 14 is supplied to the main memory 5 via the bus 2 and written into the main memory 5.

Thereafter, the CPU 1 advances the game based on a game program recorded in the main memory 5 or a command input by the game player via the controller 21. That is, the CPU 1 appropriately performs control of image processing, control of audio processing, control of internal processing, and the like based on the game program or the contents of instructions from the game player. Here, the control of the image processing includes, for example, issuance of a coordinate conversion processing instruction or a light source calculation processing instruction to the graphics data generation processor 3 and issuance of various drawing processing instructions to the drawing processing processor 10. The control of the audio processing is, for example, issuance of an audio output command to the audio processor 12, designation of a level or reverb, and the like. The control of the internal processing is, for example, an operation or the like in accordance with an operation of the controller 21.

Here, as an example of the control of the image processing, an operation in the case of displaying an image of a three-dimensional object (object) using polygons on the television monitor 22 will be described.
That is, as a premise, a table for storing the absolute coordinate data of the polygons forming the object, the rotation amount data of the object, and the movement amount data of the object is created on the main memory 5. Further, a table storing the above-described texture address data and color pallet address data is created on the main memory 5.

Next, the CPU 1 reads the rotation amount data of the object, the movement amount data of the object, and the absolute coordinate data of the polygon from the above-mentioned table, and transfers them to the graphics data generation processor 3. Next, the graphics data generation processor 3 converts the absolute coordinate data of the polygon into polygon vertex address data based on the transferred rotation amount data and the movement amount data of the object. Subsequently, the graphics data generation processor 3
Transfers the generated polygon vertex address data to the CPU 1.

Next, the CPU 1 reads out the texture address data and the color pallet address data from the above-mentioned table, and transfers these data and the polygon vertex address data to the drawing processor 10.

Next, the drawing processor 10 determines the range of the polygon surface based on the polygon vertex address data.
(A range surrounded by a straight line connecting the vertices of the polygon) is set on the display area of the buffer 11. Subsequently, the rendering processor 10 outputs texture address data,
Based on the color palette address data, texture data and color palette data corresponding to the polygon vertex address data are read from the non-display area of the buffer 11. Subsequently, the drawing processor 10
Writes the read drawing data in the range of the set polygon surface. This process is generally called “texture pasting”. Thus, the display area of the buffer 11 stores the display image data of the object. Then, the rendering processor 10
Of the display area (display image data) is output to the television monitor 22. [Image Display Processing Method by Video Game Machine] Next, an image display processing method by the video game machine will be described. FIG.

In implementing the image display processing method of the present invention, it is assumed that the video game machine has image data (texture data) of an object composed of a plurality of types of animation pattern model images. For example,
As shown in FIG. 2, image data of an object A indicating a flag composed of five animation pattern models (hereinafter, referred to as "models") A1 to A5 is held. Display numbers 1 to 5 are assigned to the models A1 to A5. The models A1 to A5 are sequentially displayed in the order of the display numbers or in the reverse order to represent the state in which the object A flutters.

Next, the video game machine sets a plurality of display positions of the image of the object A on the screen of the television monitor 22. For example, as shown in FIG. 3, five display positions P1 to P5 on the screen are determined so that a plurality of flags are arranged in an M shape.

Next, the video game machine moves to the display positions P1 to P1.
Based on P5, the models A1 to A5 of the object A are displayed on the screen of the television monitor 22, for example, in one frame. For example, as shown in FIG. 4, a model A1 is displayed at a display position P1, a model A2 is displayed at a display position P2, a model A3 is displayed at a display position P3,
The model A4 is displayed at the display position P4, and the model A5 is displayed at the display position P5.

Next, in the next frame, the video game machine displays the models A1 to A5 at the display positions P1 to P5, respectively. At this time, the video game machine displays, at the display positions P1 to P5, the models to which the display numbers immediately before the display numbers of the previously displayed models are assigned. That is, as shown in FIG. 5, the model A1 assigned the display number (display number 1) immediately before the display number (display number 2) of the model A2 displayed earlier is assigned to the display position P2. indicate. Similarly, the display position P3
Indicates the model A3, and the display position P4 indicates the model A3.
Is displayed, and the model A4 is displayed at the display position P5. However, at the display position P1 where the model A1 (display number 1) is displayed first, the model A5 (display number 5) is displayed as the model to which the previous display number is assigned.

Next, the video game machine sets each display position P in the next frame using the same method as in the previous frame.
The models A1 to A5 are displayed on 1 to P5, respectively. That is, as shown in FIG. 6, the model A4 is displayed at the display position P1, the model A5 is displayed at the display position P2, the model A1 is displayed at the display position P3, and the display position P
4 shows the model A2, and the display position P5 shows the model A2.
3 is displayed.

Subsequently, in the video game machine, each model A1 displayed at the display positions P1 to P5 is operated in the same manner.
A5 are replaced according to the display number (see FIGS. 7 and 8). As described above, the display positions P1 to P5 are
Are displayed by moving the models A1 to A5 clockwise (see arrows in FIG. 4). Then, finally, each of the models A1 to A5 displayed at each of the display positions P1 to P5 is shown in FIG.
Return to the original display position shown in.

Through these steps (the steps shown in FIGS. 4 to 8), the display positions P1 to P5 are
The models A1 to A5 are displayed in the reverse order of the display numbers. That is, the fluttering state of the object A indicating the flag is displayed at each of the display positions P1 to P5. [Processing by Video Game Machine] Next, processing of the video game machine when the above-described image display processing method is performed will be described. FIG. 9 is a functional block diagram showing a configuration (image display processing device) for performing image display processing of the video game machine.

The CPU 1 of the video game machine has a CD-RO
The game program read from M23 and loaded into the main memory 5 is executed. Thereby, as shown in FIG. 9, the game execution unit 1a, the position determination unit 1b, and the image processing unit 1c are realized as functions by the CPU 1 executing the program. In this image display processing, a counter 1d provided in the CPU 1 is used. In addition, a table 5a used for image display processing is created on the main memory 5 as the game program is loaded from the CD-ROM 23 into the main memory 5.

FIG. 10 is a diagram showing a table 5a created on the main memory 5. In this table 5a,
The absolute coordinate data of the polygon for determining the display positions P1 to P5 is stored. The above-described display positions P1 to P5 are determined by the graphics data generation processor 3 performing coordinate transformation of the absolute coordinate data of the polygon, which is the coordinate position of each vertex of the polygon in the three-dimensional absolute coordinate system set in the video game machine. Is done.

Tables 5a include models A1 to A
Five combinations of five display numbers are stored in a state corresponding to each of the display positions P1 to P5. These display numbers are stored in the display positions P1 to P5 arranged in the order of the display numbers. The table 5a stores the value of the counter 1d corresponding to each combination of the display numbers.

Although not shown, the table 5a stores light source calculation processing data (vector data of a light ray, normal data of a polygon surface), texture address data, and color palette address data of the models A1 to A5. Is stored.

The game execution section 1a shown in FIG.
-Advance the game by executing the game program loaded from the ROM 23 into the main memory 5. The game execution unit 1a issues a command (flag display command) for displaying a plurality of flag images on the screen of the television monitor 22 to the position determination unit 1b for each frame according to the game program.

When receiving the flag display command from the game execution unit 1a, the position determination unit 1b acquires the value stored in the counter 1d and decrements the value of the counter 1d by one. Then, the position determination unit 1b
The value of d is given to the image processing section 1c together with the flag display command.

When the image processing unit 1c receives the flag display command from the position determining unit 1b, the image processing unit 1c calculates the flag based on the value of the counter 1d.
Display number of each model A1 to A5 and each display position P1 to P5
And Thereby, each display position P1 to P5
Are determined respectively.
(Equivalent to change means). Subsequently, the image processing unit 1c transfers the absolute coordinate data of each of the display positions P1 to P5 to the graphics data generation processor 3. When receiving the polygon vertex address data from the graphics data generation processor 3, the image processor 1 c transfers the polygon vertex address data to the rendering processor 10.

The counter 1d is "5" in the initial state.
Is set to be stored. This counter 1d
Is decremented by one each time the position determination unit 1b acquires the counter value. The counter 1d is set so that the counter value returns to "5" when the counter value becomes "0".

Graphics data generation processor 3
Receives the absolute coordinate data of the models A1 to A5 from the image processing unit 1c, converts the absolute coordinate data into polygon vertex address data, and transfers the data to the image processing unit 1c.

The non-display area of the buffer 11 includes a CD.
-Texture data and color pallet data of the models A1 to A5 of the object A read from the ROM 23 are respectively stored (corresponding to image storage means).

The drawing processor 10 includes the image processing unit 1
When the polygon vertex address data of each of the models A1 to A5 is received from c, display image data of the models A1 to A5 is generated based on the polygon vertex address data, the corresponding texture data, and the color palette address data. The data is stored in the display area of the buffer 11. Then, the drawing processor 10 transfers the storage contents of the display area of the buffer 11 to the television monitor 22 every frame time (corresponding to a display output unit).

Next, the image display processing by the video game machine will be described with reference to the flowchart of FIG.
In this processing, a game program and data required for image display processing are loaded into the main memory 5, a table 5a is created, and texture data of the models A1 to A5 and color palette data are stored in a non-display area of the buffer 11. In the state where is loaded, for example,
The operation starts when the start button 21b of the controller 21 is pressed. It is also assumed that a counter value "5" is stored in the counter 1d at the start time, for example.

In S01, the game execution unit 1a issues a flag display command according to the execution of the game program, and gives the flag display instruction to the position determination unit 1b. Then, the process proceeds to S02.

In S02, the position determining unit 1b, which has received the flag display command, acquires the counter value from the counter 1d,
The value is given to the image processing unit 1c together with the flag display command. Here, the counter value “5” is obtained. Then, the process proceeds to S03.

In S03, the position determining section 1b decrements the value of the counter 1d by one. Here, the counter value is “4”. Then, the process proceeds to S04. S04
Then, the image processing unit 1d having received the flag display command and the counter value searches the table 5a using the counter value as a search key, acquires a combination of display numbers corresponding to the counter value, and displays each display number and each display position. P1 to P5 are associated with each other. Thereby, the models A1 to A5 to be displayed at the respective display positions P1 to P5 are respectively determined. Here, since the counter value is “5”, the model A1 is placed at the display position P1.
Is displayed, the model A2 is displayed at the display position P2, the model A3 is displayed at the display position P3, and the model A is displayed at the display position P4.
4, and it is determined that the model A5 is to be displayed at the display position P5. Then, the process proceeds to S05.

In S05, the drawing processor 1c transfers the absolute coordinate data of each of the display positions P1 to P5 and the light source calculation processing data corresponding to each of the absolute coordinate data to the graphics data generation processor 3. Then, the process proceeds to S06.

By the processing of S05, the graphics data generation processor 3 performs the coordinate conversion processing and the light source calculation processing for each of the models A1 to A5 at the display positions P1 to P5. Address data, luminance data) to the image processing unit 1c.

In S06, the image processing section 1c stores the polygon vertex address data and the luminance data received from the graphics data
To be stored. Then, the process proceeds to S07.

In S07, the image processing section 1c determines whether or not all the polygon vertex address data, that is, the polygon vertex address data of the models A1 to A5 has been stored in the main memory 5. At this time, if all polygon vertex address data is not stored (S0
(7: NO), the process returns to S05, and the processes of S05 to S07 are repeatedly performed until a determination of YES is made in S07. On the other hand, if all the polygon vertex address data has been stored (S07: YES), the process proceeds to S08.

When the processing has proceeded to S08, the image processing section 1c reads out the texture address data and the color pallet address data corresponding to the models A1 to A5 from the main memory 5, respectively, and receives the respective data received in S06. The data is transferred to the rendering processor 10 together with the polygon vertex address data and the luminance data. Then, the process proceeds to S09.

At S09, it is determined whether or not the image processing unit 1c has transferred all the polygon vertex address data, luminance data, texture address data, and color palette address data to the rendering processor 10 (models A1 to A5). Is determined. At this time, if not all data has been transferred (S09: NO), the process returns to S08, and the process returns to S08 until YES is determined in S09.
And the processing of S09 are repeatedly performed. On the other hand, if all data has been transferred (S09: YES), the process proceeds to S10.

By the processing of S09, the drawing processor 10 determines, based on the polygon vertex address data of the models A1 to A5 received from the image processing section 1c.
Display positions P1 to P in the display area of the buffer 11
Set 5. Subsequently, the drawing processor 10 checks the models A1 to A1 stored in the non-display area of the buffer 11.
Based on the texture data of A5 and the color pallet data, each model A1 at the display positions P1 to P5
The display image data of A5 is generated and stored in the display area of the buffer 11. Then, the drawing processor 10
Indicates the contents stored in the display area of the buffer 11 (model A
1 to A5) are output to the television monitor 22 as display contents for one frame. Thus, the images of the models A1 to A5 are displayed on the screen of the television monitor 22 at the display positions P1 to P5, respectively, according to the contents determined in S04 (FIG. 4).
reference).

When the process has proceeded to S10, it is determined whether or not the image display process has been completed. At this time, if it is determined that the process is not completed (S10: NO), the process returns to S01, and the processes of S01 to S10 are repeatedly performed until a determination of YES is made in S10. On the other hand, when it is determined that the process is completed (S10: YES)
Then, the image display processing ends.

In the processing of S01 to S10 in the second and subsequent rounds, the counter value obtained in S02 is a value decremented by one, so the combination of the display numbers determined in S04 changes. . In the above example,
Since the combination of the display numbers corresponding to the counter value “5” has been acquired in the first round of S04, the second round of S04
Then, the combination of the display numbers corresponding to the counter value "4" is obtained, and in S04 in the third round, the combination of the display numbers corresponding to the counter value "3" is obtained.

Here, as described above, each display number corresponding to each of the display positions P1 to P5 of the table 5a is set to be a display number reduced by one each time the counter value is decremented by one (see FIG. 4). (See FIG. 10). Therefore, at the display positions P1 to P5 on the screen of the television monitor 22,
The images of the models A1 to A5 are displayed in the reverse order of the display numbers (5, 4, 3,
2, 1, 5,...) Are sequentially displayed for each frame. That is, the display positions of the images of the models A1 to A5 are shifted by one clockwise for each frame.

Therefore, for example, in the first cycle of S01 to S09
4 is displayed on the screen of the television monitor 22 by the processing shown in FIG.
If the screen shown in is displayed, process the next frame
The screen shown in FIG. 5 is displayed by (processing of S01 to S09 in the second round), and the processing of the next frame (S
01 to S09), the screen shown in FIG. 6 is displayed. Then, in the next frame, the screen shown in FIG. 7 is displayed, and in the next frame, the screen shown in FIG. 8 is displayed,
In the next frame, the screen shown in FIG. 4 will be displayed. That is, on the screen of the television monitor 22, a state in which the objects A indicating the five flags arranged at the display positions P1 to P5 are fluttering separately is displayed. According to the image display processing apparatus, the image display processing method, and the recording medium on which the computer program is recorded, the display positions P1 to P5 of the object A indicating the flag on the television monitor 22 are set. In each of the display positions P1 to P5, the models A1 to A5 of the object A are changed and displayed for each frame in the reverse order of the display numbers.

For this reason, a state in which five flags are fluttering can be represented by only one type of model A1 to A5 of the object A. At this time, since different models are set at the display positions P1 to P5 in each process, different flags are displayed at the display positions P1 to P5 to the viewer of the screen of the television monitor 22. You can make it look like you are fluttering in a separate pattern.

Therefore, there is no need to prepare an object or an animation pattern model according to the number of flags to be simultaneously displayed on the television monitor 22 unlike the conventional case.
Thus, the amount of image data held by the video game machine can be reduced. If such an image display processing method is adopted in a video game machine that executes a sports game such as soccer or baseball, a display of a cheering flag or a team flag with a sense of reality with less data than before can be displayed on the screen. Can be.

In this embodiment, the models A1 to A5
The display positions P1 to P5 are set in accordance with the number of models.

In this embodiment, the display positions P1 to P
5 is fixed, and the models A1 to A5 displayed at the respective display positions P1 to P5 are set so as to correspond to each process of one frame. For example, each of the models A1 to A5 is set to P5, P4, P3 for each frame. , P2, P1, P5,... Also, for example, the controller 2
It may be set so that the viewpoint position with respect to the object on the screen is changed according to the operation 1, and the display positions P1 to P5 are set according to the viewpoint position. In this case, for example, the coordinate data of the viewpoint position, the rotation amount data of the viewpoint position, the movement amount data of the viewpoint position, the models A1 to A1
The display position may be determined by storing the position (absolute coordinate) data of A5 and the like in the main memory 5 and obtaining the absolute coordinate data of the polygon based on these data. In the present embodiment, the models A1 to A5 at the display positions P1 to P5 are set to be changed every frame, but may be changed every two or three frames, for example.

In this embodiment, the models A1 to A5
Are displayed in reverse order of the display number, but the model A
1 to A5 may be displayed in the order of display numbers. In this embodiment, each model A1 to A1
Although the position of 5 is shifted one clockwise, it may be counterclockwise. In short, it is only necessary that the object A is displayed in animation at each of the display positions P1 to P5 by changing the models A1 to A5 for each frame.

Further, in the present embodiment, the object A indicating the flag is illustrated, but the object is not limited to the flag. Further, in the present embodiment, the case has been described where the object A indicating the flag is three-dimensionally represented using polygons, but the object A may be a normal two-dimensional image.

Further, the image display processing method according to the present invention
It is widely practiced for video game machines that execute video games such as action games, role playing games, and adventure games, in addition to sports games such as soccer and baseball.

In the present embodiment, a home video game machine has been described, but the video game machine may be configured for business use. In this case, all of the components shown in FIG. 1 are housed in one integrated housing. Further, the video game machine may be configured with a computer such as a personal computer or a workstation as a core. In this case, the above-described television monitor 22 corresponds to a display for a computer, and the above-described drawing processor 10, audio processor 12, and decompression circuit 7 include a hardware on an expansion board mounted in an expansion slot of the computer. Interface circuit 4, parallel port 8, serial port 9, interface circuit 1
Reference numeral 9 corresponds to hardware on an expansion board mounted on an expansion slot of the computer. The buffers 11, 13, and 15 correspond to respective areas of the main memory 5 or an extended memory (not shown).
