Abstract: A YUV format to be stored in a memory is selected from A or B by a format judging unit for RGB data that is the input output display data of a memory unit, based on the comparison between chrominance (U, V) difference information on horizontal two pixels and the threshold values of U difference and V difference to be resistor-set at a format judging unit. The YUV data and information of A or B that are YUV format-converted at the format conversion unit are stored in the memory.
