Abstract:
A graphic processor comprising:a rendering control circuit controlling an operation to store pixel data of source image information onto a memory in accordance with a result of decoding a plurality of commands which include a blend processing command which causes a blend processing to be carried out in accordance with area information; and a display control circuit controlling an operation to read out pixel data from said memory synchronously with display scanning timing in a scanning direction, wherein pieces of pixel data of said source image information having an area included in said area information, are arranged on said memory to form a pixel-data matrix corresponding to a pixel matrix with columns of said pixel-data matrix being oriented perpendicularly to said scanning direction, and wherein said rendering control circuit is capable of carrying out said blend processing to correct said source image information by calculating a weighted average of pieces of pixel data located adjacent to each other which are laid out on the same column of said pixel-data matrix perpendicular to said scanning direction.
