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