PROBLEM TO BE SOLVED: To provide a device and method for noise reduction for evaluating noise in an image and an error caused by motion compensation. SOLUTION: In the device comprising: a motion-compensated interpolation means; a recursive filter intended to receive an output of the recursive filter motion-compensated by the interpolation means, at a first input side and to receive a video signal at a second input side; and a means for calculating the difference between the video signal and the output of the recursive filter motion-compensated by the interpolation means, the device includes a means for providing the video signal to the first input side of the recursive filter if the difference is greater than a predetermined noise level threshold, or providing the motion-compensated output of the recursive filter to the first input side of the recursive filter if the difference is less than the predetermined level threshold.
