Abstract
PURPOSE: To enable variableness of a flashing cycle and two colors or more of a flashing display by generating a clock corresponding to a plurality of bits of color information in accordance with selecting signals, and periodically converting and outputting the color information corresponding in response to this clock, based on the attribute information. CONSTITUTION: A color information conversion circuit 1 comprises a part of the screen display circuit of a computer, indicating a case of structure with two bits of color information (four color display) and one bit of attribute information for each bit. The attribute information is a data for controlling on-off for converting periodical color information. Two kinds of clock 1, 2, having mutually different periods corresponding to the color information 1, 2 of each bit of the two bits for a screen display outputted from a video memory, are transmitted from the clock generating circuit 2 to the conversion circuit 3 in accordance with the selecting signal, where the color information 1, 2 corresponding to the clock is periodically converted, imparted to a pallet circuit, and then, after converted to chrominance components in the pallet circuit, transmitted to a CRT for a display on the screen.
