Zusammenfassung: | PURPOSE: To display the background in the state of reducing the arithmetic load on a CPU by generating two-dimensional perspective image data seeing through three-dimensional image data, generating other two-dimensional image data responding to the coordinate move of three-dimensional image data, and synchronously displaying those respective image data. CONSTITUTION: The two-dimensional perspective image data seeing through the three-dimensional image data of a display body are generated by a main CPU 101, first VDP 120, VRAM 121 and frame buffers 122 and 123. Besides, the other two-dimensional image data responding to the coordinate move of three-dimensional image data are generated by the main CPU 101, second VDP 130 and VRAM 131. Then, these respective generated image data are synchronously displayed by the main CPU 101, second VDP 130, encoder 160 and TV receiver 5. Thus, the entire part or one part of the background can be suitably displayed in the state of reducing the arithmetic load on the main CPU 101. |
