Abstract
PURPOSE: To prevent flickering caused at the time of changeover by providing a simple delay circuit at a control signal supplied from a CPU to a picture display device and arranging a means outputting RGB color data corresponding to color codes displayed at other than a display screen. CONSTITUTION: The control signal, the inverse of, CE, supplied from a display controller to the picture display device is connected to an AND gate 50 through the delay circuit 60. Thus, until the RGB color data corresponding to the color codes of the display controller(VDC) 20 at other than the display screen at the time of access changeover to the VDC 20 is outputted from access from the CPU 10, the RGB color data obtained by the access from the CPU 10 is not outputted. Therefore, the flickering is prevented.
