ABSTRACT:
Multiplier and multiplicand output means is connected to multiplier means having a multiplier and multiplicand input section. The multiplier and multiplicand output means produces second matrix coefficient signals in response to first matrix coefficient signals, automatic chroma control signal and adjustment signal. The second matrix coefficient signals are inputted to the multiplier on a time-sharing basis and are multiplied with an input digital chroma signal in this multiplier. The second matrix coefficient signals include an automatic chroma control component, color saturation control component and hue control component.
