Abstract

PURPOSE: To simplify a changeover among display colors extremely by simple constitution, by providing a switch circuit between several picture memories and two output circuits and by selectively connecting both circuits by switching.
CONSTITUTION: Picture memories 11 and 12 are stored with graphic pattern information through the classification by display colors, and output circuits 13 and 14 add fixed-color information to graphic pattern information read out from memories 13 and 14 and then outputs it. Then, information from circuits 13 and 14 is sent to the display unit, where a picture is formed, and switch circuit 15 is provided between circuits 13 and 14, and memories 11 and 12, thereby making a selective connection between the both by switching. The simple constitution can therefore simplify the changeover among display colors.
