Andrew J Patti, Jonathan K Riek, M Ibrahim Sezan: Contour-sensitive, single-field deinterlacing method. National Science Council, Madson & Metcalf, February 11, 1997: US05602654 (39 worldwide citation)

The present invention is a two-step, contour-sensitive deinterlacing technique. The first step of the technique determines for each missing pixel of an interlaced frame of image pixels whether the absolute difference between the pixels above and below the missing pixel is greater than a preselected ...

M Ibrahim Sezan, Andrew J Patti: Mechanism for controllably deinterlacing sequential lines of video data field based upon pixel signals associated with four successive interlaced video fields. Eastman Kodak Company, Peyton C Watkins, May 28, 1996: US05521644 (33 worldwide citation)

A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame, which is generated by using four consecutive fields to produce a motion detection map that is subsequently coupled to a deinterlacer, together with a selected tw ...
