The processing of signals of television adapting to the movement

摘要

A motion adaptive television signal processing system is disclosed. An image change estimator estimates the image change over an image time interval. A television signal processor adaptively processes the signal in response to a control signal. A control signal generator is coupled between the image change estimator and the adaptive television signal processor. The control signal generated exhibits a function substantially described by: K=Ae-b/x where K is the value of the control signal, A is the maximum value the control signal can attain, x is the estimated image change, and b is a constant. In a second embodiment, a second estimator estimates a parameter of the television signal. The relationship of the control signal to the estimated image change is varied as a function of the estimated parameter.
