Abstract (en)

Color palette circuits are disclosed which utilize first and second color look-up tables which use information from a video bit map to address storage locations in the look-up tables, and then combine the information stored in the selected storage locations using digital adder or digital multiplier circuits, the resulting combined signals are then converted to analog signals, which may be used to generate color pixels. The use of a combining means permits the generation of a greater number of displayable colors than the sum of the number of storage locations in the look-up tables.
