ABSTRACT:
A motion detecting circuit for a video signal processor having a filter arrangement for separating the video signal into the low and high frequency components, a first detecting circuit for detecting a low frequency luminance moving signal, a second detecting circuit for detecting a high frequency luminance moving signal, a third detecting circuit for detecting a chrominance moving signal, a first threshold circuit for generating a low band luminance motion digit signal, a second threshold circuit for generating a high band luminance motion digit signal, a control circuit coupled for generating a control signal in response to the low and high band luminance motion digit signals, a gate circuit for selectively transmitting the chrominance moving signal in response to the control signal and a selector for selectively outputting the one of the low frequency luminance moving signal and the chrominance moving signal having the high signal intensity.
