ABSTRACT:
An image synthesizing system capable of synthesizing a high-quality image in real time is provided herein. The image synthesizing system is adapted to process a plurality of overlapping polygons sequentially starting from the closest polygon to the view point in a scene. An end flag storage unit stores an end flag at an address corresponding to the processed dot. A processing dot instruction unit reads out this end flag which in turn is used to indicate a dot to be processed to a processor unit. In such a case, the processing dot instruction unit instructs the processor unit so that the end flag of the dot decided to be processed is written back into the end flag storage unit while at the same time only the dot to be processed is treated. Thus, the image synthesization can sequentially be carried out to the polygons starting from the closest polygon to the view point in the scene. At the same time, the computing process to the hidden portion of polygons which have been processed can be omitted.
