Patent ID: 8633935

Claim:
A rendering processor comprising a main processor, a first sub-processor that processes information output from said main processor, and a second sub-processor that processes information output from said first sub-processor, said main processor comprising: a main processor output unit that, in a case where a rendering target image is divided into two regions, outputs first information for rendering one region and second information for rendering another region to the first sub-processor, said first sub-processor comprising: a first transfer unit that outputs the second information, output from said main processor output unit, to said second sub-processor; a first rendering unit that renders the one region using the first information, output from said main processor output unit; and a first output unit that outputs a rendering result by said first rendering unit to said second sub-processor, and said second sub-processor comprising: a second rendering unit that renders the other region using the second information output from said first sub-processor; and a second output unit that outputs the rendering result output from said first sub-processor and a rendering result by said second rendering unit.
