Abstract
Improvements in tone correction circuits for color television receivers, of the type comprising processing circuitry sensitive to the chrominance signals contained in a color television signal, the receiver of which comprises a color reference oscillator and modulator means of color, whose demodulating means are sensitive to said chrominance signals and to said color reference oscillator to produce, at an output, demodulated color signals, characterized in that said tone correction circuits comprise detection means sensitive to said chrominance signals for detecting components that have a phase representative of the tones close to the tones of the meat, and phase shifting means coupled to said detection means to change the phase of the waves coming from said color oscillator when a chrominance signal is detected that it has a representative phase of the shades in l as close to the tones of the meat.
