ABSTRACT:
An automatic chrominance gain control circuit for a color television receiver distinguishes between lower frequency chrominance variations (large color objects) and higher frequency chrominance variations (small objects) to minimize gain control for large color objects and to emphasize gain control for highly saturated contrasting colors in small objects across the picture field.
