Abstract
A method and apparatus for performing color space conversion using blend circuitry in a graphics/video adapter is provided. Blend circuitry which is capable of blending two color values and fog circuitry which is capable of adjusting color values based on a fog factor are used. A first stage of converting a color value from YC.sub.r C.sub.b (YUV) color space to RGB color space is performed using the fog circuitry, and a second stage of converting the color value from the YC.sub.r C.sub.b (YUV) color space to RGB color space is performed using the blend circuitry, resulting in the generation of a converted color value .
