PROBLEM TO BE SOLVED: To provide an image processor capable of efficiently performing rendering processing accompanied with blend processing of a translucent polygon. SOLUTION: In rendering processing of the translucent polygon, work data Xn as the cumulative multiplied values of transparency are found successively from the polygon of the front side in a display picture, and light source calculating processing for finding color data INTn from a light source or texture processing for finding color data TXCOn while utilizing a texture color or the like is parallel performed to plural polygons. Then, color synthesizing processing of plural polygons is performed at random for finding and accumulating image data FBn from the work data Xn-1, light source image data INTn, color data TXCOn and a opacityαn. |
