Hue correction apparatus controlled by chrominance saturation

In a system for processing color television signals including chrominance signals having a phase representative of hue and an amplitude representative of saturation of colors present in a scene, said television signals further including a reference subcarrier signal having a nominal phase relative to said chrominance signals, hue correction apparatus comprising:

• means having at least a first input responsive to said reference subcarrier signal and at least a second input responsive to said chrominance signals for providing a gating signal representative of a phase relationship between said chrominance signals and chrominance signals representative of flesh tones as determined by the nominal phase of said reference subcarrier;
• signal modulating means responsive to said chrominance signals and to said gating signal for passing a selected amplitude portion of said chrominance signals;
• signal combining means responsive to said reference subcarrier signal and to said selected amplitude portion of said chrominance signals for providing a corrected reference subcarrier having a phase modified towards the phase of said chrominance signals according to said selected amplitude portion of said chrominance signals;
• and
• control means responsive to the amplitude of said chrominance signals for providing a control signal for reducing the amplitude of said selected amplitude portion of said chrominance signals so as to reduce the correction of said reference subcarrier phase in the presence of chrominance signals having an amplitude representative of relatively saturated colors.
