Kenneth A Boehlke: Motion adaptive de-interlace filter. Focus Enhancements, Daniel J Bedell, Smith Hill and Bedell, December 11, 2001: US06330032 (21 worldwide citation)

The invention provides a method for filtering motion effects from a de-interlaced image and an apparatus associated therewith. The method assumes that the de-interlaced image is formed by a combination of a first interlaced image and a second interlaced image. A first step in the method is to interp ...

Steven R Morton, Kenneth Alfred Boehlke: Video signal converter utilizing a subcarrier-based encoder. Focus Enhancements, Christopher P Ricci, May 18, 1999: US05905536 (13 worldwide citation)

A video converter converts an input video signal conveying pixel data representing an M.times.K pixel image to an output video signal conveying data representing an N.times.L pixel image. The converter samples the input video signal to acquire an M.times.K matrix of pixel data, re-encodes each pixel ...
