摘要： A color resolution compensator for a color television receiver improves the resolution of a reproduced color picture by mixing a high frequency component of a luminance signal to a color difference signal to generate a signal to be fed to the color demodulators of the television receiver. Various portions of the luminance signal and the color difference signal may be optimally selected in dependence upon various predetermined design parameters.

摘要： A flesh correction circuit for a color television receiver includes a reference flesh signal generator for generating a signal corresponding to flesh tone, a flesh signal detector for detecting a flesh signal of a carrier chrominance signal, a carrier chrominance signal corrector for correcting the carrier chrominance signal by mixing the carrier chrominance signal and an output signal of the reference flesh signal generator with a mixing ratio controlled by an output signal of the flesh signal detector.
