Abstract

The deblurring deconvolution is dependent upon the capture time T of the image and the motion vector detected for that part of the image. A multiplexer 14 selects between deblurring deconvolutions performed in parallel in dependence upon a plurality of different candidate motion vectors V1, V2, V3 and zero motion. A region processor 10 identifies boundaries between areas within the image corresponding to different objects and controls a mixer 16 to selectively output deblurred values or unprocessed raw video values so as to reduce edge effects due to the inappropriate application of deblurring deconvolution at the edges between objects. Provision of parallel deconvolutions allows the system to operate in a continuous pipelined manner. <IMAGE>
