Abstract
PURPOSE: To perform quantized display without increasing the number of density converters, by using one density converter only, and controlling the readout address for the contrast or color code.
CONSTITUTION: The picture information stored in the picture memory 2 is sequentially read out, and picture is displayed via the density converter 4 consisting of RAM to assign the contrast or color corresponding to the density. In such a display unit, the area designator 3 designating one or more of arbitrary shape in the picture memory 2, and the quantized control unit 5 controlling the readout address of density of color code from the density converter 4 to change the display density level of this area are provided, allowing to emphasize and display in the display density level different every emphasized area at display.
