摘要： A temporally recursive chrominance signal noise reduction can be achieved by subtracting a delayed version of the chrominance output signal from the chrominance input signal and by multiplying the related difference signal by a variable share factor and adding the resulting signal to the chrominance output signal, for achieving different degrees of noise reduction. From the difference signal a motion representative value and a value representing the presence of a smear effect are calculated and used to calculate the variable factor. After having been multiplied by this factor, the difference signal is combined with a frame-delayed version of the chrominance output signal in order to form the noise-reduced chrominance output signal.
