Abstract
A video display controller which can display foregrounds as well as backgrounds of display patterns on a screen of a video display unit in a plurality of colors. The video display controller comprises a plurality of color information registers, in each of which a pair of color code data representative of foreground and background colors of one display pattern are stored. A memory is provided for storing a plurality of pattern data, a plurality of pattern name data each designating one of the display patterns to be displayed on a respective one of display portions of the screen, and a plurality of color selection data each corresponding to a respective one of the display portions. A sequence controller sequentially reads the pattern data designated by the pattern name data and the color selection data in accordance with synchronization signals. A color selection control logic circuit selects one of the color information registers in accordance with the color selection data read from the memory, and reads one of the pair of color code data from the selected color information register. A color signal generator generates a color signal in accordance with the color code data read from the register and supplies it to the video display unit.
