Abstract
A video display control system displays a multicolor animation pattern on a screen of a video display unit. The video display control system is mainly constructed by a video RAM (VRAM) and a video display processor (VDP). The VRAM stores animation pattern data, display position data and at least two color data. The VDP reads these data and makes an animation pattern image displayed in at least two colors at a display position on the screen. The animation pattern image, two colors and display position are determined by the animation pattern data, two color data and display position data. In another video display control system, the VRAM stores at least two sets of animation pattern data, display position data and color data. When displaying two animation patterns, the VDP effects a logical operation on the two color data with respect to the overlapping portion of the two patterns and makes the overlapping portion displayed in a new color corresponding to the operation result. When the animation patterns overlaps, the VDP can also deliver a collision signal in place of the logical operation, thereby enabling a CPU to recognize the position of the overlapping portion.
