ABSTRACT:
The disclosure relates to a device and to a method for noise reduction of a video signal. The device is comprised of the following components. A motion-compensated interpolation means, a recursive filter intended to receive the output of the recursive filter motion-compensated by the interpolation means at a first input, and the video signal at a second input;means for calculating the difference between the video signal and the output of the recursive filter motion-compensated by the interpolation means;wherein the device includes means for providing the first input of the recursive filter either with the video signal if the difference is greater than a predetermined noise level threshold, or the motion-compensated output of the recursive filter, if the difference is less than the said predetermined noise level threshold.
