ABSTRACT:
A chrominance signal controlling apparatus for controlling the chrominance signal in a color television receiver employing a primary color signal demodulator providing red, green and blue primary color signals and not providing color difference signals comprises a luminance signal producing circuit for producing a luminance signal by mixing the three primary color signals, a subtracting circuit for producing a difference signal between one of the primary color signals and the luminance signal, and a comparing circuit for producing a control signal for controlling the chrominance signal level and/or phase by keeping the difference signal equal to a reference level.
