Abstract

In video processing, a motion vector is identifed for each of a plurality of overlapping picture blocks. Pictures are then shifted in accordance with the motion vectors to provide multiple shifted pictures, and these are combined with weightings derived from the proximity of the associated pixel to the respective blocks.
