Abstract
PURPOSE: To make a raster scan-system display high-speed by storing section information, which indicates the same luminance level section, and luminance level information, which indicates a luminance level in the same luminance level section, in a buffer memory for screen refresh.
CONSTITUTION: Section information indicating the same luminance level section and luminance level infomation indicating the absolute value of a luminance level in each section or the relative value to the just preceding section are received from a central processing room and are stored in a buffer memory for screen refresh. Then, section information and luminance level information are read out from buffer memory successively to generate a luminance signal for every section, and this signal is supplied to a display part to display a prescribed variable density pattern. Thus, since a fine variable density pattern can be displayed in a high speed on a basis of section information and luminance level information and the luminance level is designated for every section of the same luminance level, the capacity of the buffer memory can be reduced.
