Patent ID: 7812884

Claim:
An apparatus comprising: a display; and a de-interlacer operative to de-interlace interlaced fields to produce an image frame comprising: recursive motion history map generating circuitry operative to determine a motion value, on a pixel by pixel or group of pixel basis, associated with one or more pixels in the interlaced fields based on pixel intensity information from at least two neighboring same polarity fields; and operative to generate a motion history map containing recursively generated motion history values for use in de-interlacing the interlaced fields wherein the recursively generated motion history values are based at least in part on a decay function; and de-interlacing circuitry operatively responsive to the recursively generated motion history values that are based at least in part on the decay function, and operative to provide de-interlaced output pixel information for display by selecting a suitable de-interlacing technique from a plurality of different techniques based on the motion history map, to produce the image frame.
