Abstract

PURPOSE: To switch and display a color graphic picture having low resolution and a monochrome graphic picture having high resolution without increasing memory capacity by selectively controlling outputs from plural picture memories. CONSTITUTION: When output data simultaneously read out from the plural picture memories 11 to 14 by the selector 161 of a control circuit 16 through a color pallet 15 is selected, the color graphic picture is displayed on a display part 17. Meanwhile, the monochrome graphic picture having the high resolution is displayed by supplying one field of output by the memories 11 and 12 read out at the rising time and falling time of a clock through the selector 163, one field of output by the memories 13 and 14 through the selector 164 succeeding to the above, and output read out in a mosaic state from the memories 11 and 12, and 13 and 14 by such repetition through the selectors 162 and 161. By such constitution, the color graphic picture having the low resolution and the monochrome graphic picture having the high resolution are switched and displayed without increasing the memory capacity.
