Color corrector

DETAILED DESCRIPTION What is claimed is: 1.
In a television receiver adapted to receive chroma signals for demodulation thereof by a (B-Y) demodulator, an (R-Y) demodulator, and means for generating a (G-Y) demodulated signal, a color corrector for automatically correcting selected chroma signals so that their effective phase is more nearly along a fleshtone axis, comprising: means for generating a control signal in response to demodulator outputs indicative of reception of chroma signals in a selected phase range encompassing the fleshtone axis; and means coupled to the (B-Y) demodulator and responsive to the control signal for modifying the gain of the (B-Y) demodulator such that the output thereof is reduced by a predetermined factor, and for adding a predetermined negative (B-Y) component to the output of the (B-Y) demodulator, the amount of said component being selected such that demodulated chroma signals occurring with said range encompassing the fleshtone axis are offset toward the fleshtone axis; whereby fleshtone chroma signals which otherwise appear too blue or too green are given a more natural color as a result of the reduced amplitude of their (B-Y) component, and the addition of said negative (B-Y) component causes the resultant color correction to be centered about the fleshtone axis.
2.
A color corrector as set forth in claim 1 wherein said modifying means adds a preselected d.
c.
voltage offset to the output of the (B-Y) demodulator.
3.
A color corrector as set forth in claim 1 wherein said control signal generating means receives demodulated (R-Y), (B-Y) and (G-Y) chroma signals and generates the control signal in response to the instantaneous value of the received (R-Y) chroma signal being greater than the instantaneous sum of the received (B-Y) and (G-Y) chroma signals, whereby the control signal is generated only for chroma signals whose phase is within a selected range of the fleshtone axis.
4.
A color corrector as set forth in claim 3 wherein the sum of the demodulated (B-Y) and (G-Y) chroma signals includes a known d
