Abstract
Motion compensated video signal processing apparatus for interpolating an output image of an output video signal from a corresponding pair of temporally adjacent input images of an input video signal comprises: means for generating a plurality of local motion vectors to represent image motion of respective search blocks of one input image of the pair between that image and the other image of the pair; means for detecting blocks of the output image pointed to by each local motion vector; means for assigning a group of motion vectors to each block of the output image, the group being selected from a set of motion vectors comprising at least those local motion vectors pointing to that block of the output image; and a motion compensated interpolator for interpolating pixels of each block of the output image from the pair of input images, using a motion vector from the group assigned to that block.
