Abstract
A noise reduction method for reducing noise in an input video signal to output an output video signal includes the steps of generating a motion-compensated reference video signal from the output video signal; delaying the output video signal to generate a non-motion-compensated reference video signal; mixing the motion-compensated reference video signal with the non-motion-compensated reference video signal to generate a reference video signal; subtracting the generated reference video signal from the input video signal to generate a differential signal; compensating the differential signal to generate a noise reduction signal; and subtracting the noise reduction signal from the input video signal.
