ABSTRACT:
A circuit in a graphics processing subsystem receives pixel color values as input and concurrently provides both dithering and scale correction of the color values. Pixel color values are initially generated by the subsystem as 8-bit binary quantities, each having a maximum possible value of 255. However, the graphics processing subsystem utilizes a scale of 0 to 256 for processing color values. The correction function prevents a loss of pixel intensity that would otherwise result from representing 8-bit color values on a 0 to 256 scale.
