Portable game machine and computer-readable recording medium

摘要

In each odd-numbered frame, a game image generated by a three-dimensional image processing unit (31) is supplied to a first LCD (11), and then a game image identical to the generated game image is stored in a first VRAM (21a). Also, a two-dimensional image processing unit (37) supplies the game image stored in the immediately-preceding even-numbered frame in a second VRAM (21b) to a second LCD (12). On the other hand, in each even-numbered frame, a game image generated by the three-dimensional image processing unit (31) is supplied to the first LCD (12), and then a game image identical to the generated game image is stored in the second VRAM (21b). Also, the two-dimensional image processing unit (37) supplies the game image stored in the immediately-preceding odd-numbered frame in the first VRAM (21a) to the first LCD (11). With this, in a portable game machine including two display units, different three-dimensional game images can be simultaneously displayed by a single three-dimensional image processing unit on the two display units without flicker on the display screens.
