Abstract
A display control system with a control of background luminance or color data applicable for a personal computer with a paper-white type display device includes a character video signal generation unit, a background luminance setting register, a video enable signal generation unit, a video signal priority unit, and a video signal synthesis unit. A first video enable signal from the video enable signal generation unit controls the supply of the video signals to the video signal priority unit. A second video enable signal from the video enable signal generation unit controls a display of background in a background luminance tone or color designated by the background luminance setting register for an intermediate range when the character video signal is absent.
