RENDERING PROCESSING APPARATUS REQUIRING LESS STORAGE CAPACITY FOR MEMORY AND METHOD THEREFOR

摘要

In a rendering processing system having a rendering memory forstoring rendering pixel data generated by a rendering operation circuit anda display memory for storing the image data of a current frame read outfrom the rendering memory, the display memory stores only the pixel dataread out from the rendering memory with prescribed information excludedtherefrom. Thus, it is possible to decrease the storage capacity of thedisplay memory and also reduce the time required for writing data into thedisplay memory.
