ABSTRACT:
A motion detector includes a flicker compensating circuit for removing flicker components from a video signal, and a motion vector detecting circuit for detecting a motion vector in response to an output signal from the flicker compensating circuit. An image stabilizing system includes a flicker compensating circuit for removing flicker components from a video signal, a motion vector detecting circuit for detecting a motion vector in response to an output signal from the flicker compensating circuit, and a motion compensating circuit for removing motion components from the video signal in response to the motion vector detected by the motion vector detecting circuit.
