Abstract
An auto-flesh circuit for a TV receiver is described which operates an I and Q color mixture signals to produce flesh corrected color mixture signals I' and Q'. The received I and Q signals are demodulated in respective circuitry to generate the magnitude and angle of their vector sum. The angle values are applied as address codes to a ROM programmed to produce the sines and cosines of the applied address codes. For address code angles corresponding to chrominance signals representing flesh tones, the values of the programmed sines and cosines correspond to values of flesh corrected chrominance angles. The sine and cosine values output by the ROM are then multiplied by the magnitude of the vector sum (chrominance magnitude) to produce corrected Q' and I' color mixture signals respectively.
