A method and apparatus for performing color space conversion using blend circuitry (154) and fog circuitry (152) in a graphics/video adapter (140). The blend circuitry is capable of blending two color values and the fog circuitry is capable of adjusting color values based on a fog factor. The fog circuitry performs the first stage of converting values from YCrCb (YUV) color space to RGB color space. The blend circuitry performs the second stage of the conversion.

Procédé et appareil destinés à exécuter une conversion d'espace de couleur à l'aide d'un circuit de mélange (154) et d'un circuit générateur de brouillard (152) dans un adaptateur graphique/vidéo (140). Le circuit de mélange est capable de mélanger deux valeurs de couleur et le circuit générateur de brouillard est capable d'ajuster les valeurs de couleur sur la base d'un facteur de brouillard. Le circuit générateur de brouillard exécute la première phase de conversion des valeurs de l'espace de couleurs de luminance, chrominance rouge, chrominance bleue YCrCb(YUV) dans l'espace de couleur RVB. Le circuit de mélange éxécute la seconde phase de la conversion.
