Switching arrangement for flesh tone correction and chrominance overload control circuits

Abstract From the Canadian patent

Abstract of the Invention, Switching apparatus is included in a color television receiver for changing the threshold of a saturation overload detector and simultaneously changing the gain characteristics of an associated chrominance signal amplifier. The overload detector is operative to limit chrominance signals at a lower level when noisy signals are present and at a higher level when relatively noise-free signals are present. The switching apparatus is arranged to avoid annoying large shifts in picture saturation upon its operation. An associated flesh tone correction circuit is enabled by the switching apparatus when the lower overload limit is employed and is disabled when the higher …
