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.

Motion compensated video signal processing

A system for integrating film material with a digital video signal employs a film scanner to produce a digital video signal from the source film, and a post production system for combining with that signal the input digital video signal. Motion interpolated temporal compensation is employed at stages of frame rate conversion.

Format conversion of digital video signals, integration of digital video

Method of integrating 30 or 60 frame/s format material and 60 field/s 2:1 interlace scan format digital video signal to produce a 60 field/s 2:1 interlace scan format digital video signal by producing a progressive scan format digital video signal from the format material, converting the progressive scan format digital video signal to a 60 field/s 2:1 interlace scan format digital video signal and combining the converted signal with the 60 field/s interlace scan format digital video signal.
