Abstract
PURPOSE: To increase S/N of luminance signal against chroma signal by controlling the gain in high luminance signal and noise-clipping in low luminance signal in proportion to the amount of detection of noise and by noise-clipping a color difference signal in proportion to the amount of detection of noise.
