  • Motion compensated video signal processing
    Patent number: 5526053
    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.

    Date of Patent: June 11, 1996
    Assignees: Sony Corporation, Sony United Kingdom Limited
    Inventors: Martin R. Dorricott, Morgan W. A. David, Shima R. Varsani
  • Format conversion of digital video signals, integration of digital video signals into photographic film material and the like, associated signal processing, and motion compensated interpolation of images
    Patent number: 5353119
    Abstract: 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.

  • Method of integrating format material and an interlace scan format signal
    Patent number: 5329309
    Abstract: 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.
