ABSTRACT:
We describe a weighted absolute difference based deinterlace method and apparatus. The deinterlace method and apparatus uses weighted absolute differences along different directions as means for interpolating pixel data using edge orientation detection. The apparatus includes a memory adapted to store a current and previous fields and predetermined portions of a future field of an input signal. A motion detector is adapted to detect motion between the future and previous fields. An interpolating circuit is adapted to generate a plurality of output pixels using a corresponding plurality of methodologies. And a switch is adapted to select between the plurality of output pixels responsive to the motion detector.
