PURPOSE:To decide colors respectively used for a graphic detecting a collision and a graphic which does not detect the collision individually by providing collision detecting registers of the number corresponding to the number of the pictures. CONSTITUTION:Since respective bits of collision designating registers 60, 61 correspond to the respective colors of the eight colors in 1:1, in order to monitor the collision of the specific graphics between the two pictures, '1' may be stored in all the bits of the collision designating registers corresponding to the colors. Thereby, when the graphics monitoring the collision are registered on the same pixel position, at the time when the pixel is displayed, a collision detecting signal 700 goes to '1', an interruption is generated in a central processing unit 2 by an interruption request signal 802, and an interruption processing by the collision is performed.
