ABSTRACT:
Method and apparatus for controlling operation of a time domain noise reduction system in a color television picture signal path by: detecting spatial picture characteristics in the path and detecting occurrence of temporal picture changes on a field by field basis, generating a control signal in relation to the detected spatial and temporal picture characteristics and applying the control signal to control time domain operation of the noise reduction system.
