Patent

CA 2319938

A graphic accelerator includes a RGB/YUV conversion unit converting color information of the RGB format included in a drawing instruction into a format which includes luminance and color difference components, a drawing instruction execution unit for compressing the color difference component converted by the RGB/YUV conversion unit to generate pixel information according to the drawing instruction, a screen data output unit expanding pixel information generated by the drawing instruction execution unit, and a YUV/RGB conversion unit which converts the pixel information expanded by the screen data output unit into pixel information of the RGB format. Therefore, the data amounts of the color difference component can be reduced to improve the processing speed.
