ABSTRACT:
According to this invention, in a display system having a CRT controller for arbitrarily and selectively display-driving a plasma display and a CRT display, display fonts inherent to the displays are prepared, and a display font corresponding to the display is selectively used and displayed in accordance with a display to be display-driven. The fonts include a plurality of types of graphics and text fonts, and are selectively used. As the text font, a single font and a double font are selectively used. When a display mode of the plasma display having a ratio of the number of dots in the vertical direction to that in the horizontal direction different from that of the CRT display is set, a specific raster of the display screen is scanned twice to stretch an image.
