ABSTRACT:
A method for processing an input digital video signal, the method comprises the steps of capturing first and second frames from the input digital video signal; determining intermediate motion vectors from the first and second frames, which intermediate motion vectors represent motion of objects between frames; and re-creating the second frame for forming a blurred first frame having pixel values determined by combining pixels in the first and second frames, wherein the combining is controlled by the intermediate motion vectors.
