PROBLEM TO BE SOLVED: To enable a sprite picture whose parallax quantity is small to be also displayed when it is not overlapped with a sprite picture whose parallax quantity is large. SOLUTION: Sort processing by a sort processing means 4 are performed in vertical blanking periods and selection processings by a selection means 8 are performed every one horizontal line in vertical display periods. Then, when selection processings with respect to odd numbered horizontal lines are performed, picture information generating procesings by picture information generating means 8, 15, 16 with respect to even numbered horizontal lines are performed and when selection processing with respect to even numbered horizontal lines are performed, picture information generating processings by the picture information generating means 8, 15, 16 with respect to odd numbered horizontal lines are performed. |
