For storing display information to be output to CRT,
A frame memory, a lookup table that uses the output from the frame memory as address information and outputs the color data of each pixel from the address, and a CRT driver that displays the color data of each pixel output from the lookup table on a CRT.
In a CRT display device configured with a display device that is controlled by an RT driver and displays color data, this is used to switch between two lookup tables, a lookup table with the same memory capacity as the lookup table already owned by this device. By providing a switching control circuit, one lookup table is always used for displaying, and the other lookup table is used for drawing, and the switching control circuit switches between the two lookup tables for each screen display. A display output control device that is capable of performing high-speed display and screen display without flickering on the screen without being aware of the drawing period and the display period.
