PROBLEM TO BE SOLVED: To provide a computer for generating video graphics of a video game, etc., with an efficient and inexpensive graphics system capable of performing interaction. SOLUTION: A graphics processor has an embedded frame buffer, and a copy line is provided between the embedded frame buffer 114 and an external frame buffer such as a main memory 112 connected directly to a display device 56. The copy line performs four types of combination conversion of data from a certain format into another format, for instance, one RGB and YUV color format into another RGB and YUV color format. The converted data are transferred to the external frame buffer or a texture buffer for being used as texture.
