  • Motion compensated de-interlacing
    Patent number: 6512550
    Abstract: A method of motion compensation using temporal support of multiple fields of video to produce a progressive frame. The moving average of the motion compensated field lines temporally adjacent to the field to be de-interlaced are used, after a non-linear filtering, as the missing lines to complete the progressive video frame.
    Type: Grant

    Inventors: Diego P. de Garrido, Kamil Metin Uz, Leslie D. Kohn, Didier LeGall
  • Motion compensated de-interlacing
    Patent number: 6331874
    Abstract: An algorithm based on motion compensation uses a temporal support of five fields of video to produce a progressive frame. The moving average of the motion compensated field lines temporally adjacent to the field to be de-interlaced are used, after a non-linear filtering, as the missing lines to complete the progressive video frame.
