Here, the program stored in the CD-ROM 2 is a video game in which a player operates a character and moves on a field to process and proceed with an event that occurs.

FIG. 3 shows an example of the video game screen described above. The character 51 is moved and displayed on the field by pressing the direction key 7 of the controller 3. With this movement, the background 52 on the field is scrolled. The background 52 on this screen is the entrance of the castle on which the drawbridge is hung.

FIG. 4 shows the state of FIG.
The screen rotated left from the viewpoint position of FIG. FIG. 5 also shows a screen which is similarly rotated rightward by pressing the R1 button 15.

FIG. 6 shows the relationship between fields and areas. The field in which the character 51 moves is divided into areas, and game data is recorded for each area. The game data of the area includes management information (see FIG. 7A) as a header and a data section (see FIG. 7B). The area 2b where the character 51 is currently displayed and the surrounding area (1
a) to 3c) are recorded in the RAM 23 which is the main storage device, and the data portion is stored in the buffer memory 3 of the CD-ROM 2.
Record in 7. The management information as a header includes a data part address, a program size, an image data size, and an audio data size. The corresponding data section is
The program, image data, and audio data are each recorded in a variable length. The management information and the data section are continuously recorded on the track 53 of the CD-ROM 2 (see FIG. 8). Thus, when the character 51 receives the movement input and moves to the area 3b, for example, the management information of the area 3b is stored in the RAM by the header address.
By reading from the buffer memory 37 and reading the corresponding data part from the buffer part 37 from the data part address of the management information, the processing time can be shortened as compared with the case of directly reading from the CD-ROM 2. When the character 51 moves to the area 62, the character (4
The game data of a to 4c) are read from the CD-ROM 2, and the game data of the areas (1a to 1c) are erased. Here, the seek time can be shortened by recording the game data of the CD-ROM 2 in the same part of the CD-ROM 2 for each area (see FIG. 8).

FIG. 9 is a functional block diagram of the present embodiment. When the input receiving unit 81 receives the pressing of the directional key 7 of the controller 3, the area recognizing unit 82 recognizes the area after the movement of the character 51. When moving to another area, the display control unit 83 reads the management information of the RAM 23 from the header address corresponding to the area No. of the area to which the character 51 has moved, and uses the data part address included in the management information to record the CD. -ROM
The data portion is read from the second buffer memory 37 with a pointer, subjected to image processing, and displayed on the display 5. Similarly, the audio output unit 84 reads the audio data from the RAM 23 and the buffer memory 37, performs a decoding process, and outputs the data to the speaker 6. The reading section 85 reads the management information and the data section from the CD-ROM 2 by using the header address corresponding to the area No. of the area adjacent to the destination area of the character 51, reads the management information into the RAM 23, and stores the data section in the CD-ROM buffer. Read into the memory 37. Further, the area data reading section 85 is provided for the character 5
The management information and data part of the area no longer adjacent to the area where 1 is displayed are deleted.

On the other hand, when the input receiving unit 81 receives the press of the L1 button 14 or the R1 button 15 of the controller 3, the display control unit 83 transmits the viewpoint change game data of the current area where the character 51 is displayed. RAM 23
The image is read from the CD-ROM buffer memory 37 and displayed on the display 5.

FIG. 8 is a flow chart showing this. That is, when the direction key 7 of the controller 3 is pressed (101), the input receiving unit 81 recognizes the area of the destination (102). To perform scroll display (11
1). On the other hand, when moving to another area (103),
The display control unit 83 stores the management information of the area in the RAM 23
And the data portion is read from the buffer memory 37 to display an image on the display 5, and the audio output portion 84 outputs audio to the speaker 6 (104). The reading unit 85 reads the game data of the area adjacent to the movement destination area from the CD-ROM 2, and reads the RAM 23 and the CD-ROM.
While reading into the ROM buffer memory 37, the game data of the area that is no longer adjacent
Erase from the D-ROM buffer memory 37 (10
5).

On the other hand, the input receiving unit 81
Alternatively, when the R1 button 15 is pressed (121), the game data in the current display area is read, and the viewpoint change display and sound output are performed (122).

As described above, according to the present embodiment, the program, image data and audio data are recorded in the CD-ROM for each area of the field, the management information of these data is stored in the RAM, and the data section is stored in the CD-ROM. By reading them into the ROM buffer memory, the background display accompanying the movement of the character can be displayed without apparent waiting time.

The management information may be recorded in the cache memory of the CPU instead of the RAM.

[0032]

According to the present invention, it is possible to provide a technology capable of displaying a background image accompanying a movement of a character in a video game using a CD-ROM without apparent waiting time.
