Method and apparatus for motion adaptive deinterlacing with reduced artifacts

A method and apparatus for generating an interpolated pixel at a vertical position half way between lines in a field of a video frame. The method comprises detecting a degree of motion in the vicinity of said interpolated pixel and providing weighting factors based on said degree of motion, and detecting a degree of variation in the vicinity of said interpolated pixel and providing a further weighting factor based on said degree of variation. The method further comprises calculating a high vertical frequency contribution, calculating a low vertical frequency contribution, calculating a weighted high vertical frequency contribution based on said high vertical frequency contribution and said further weighting factor, calculating a total vertical contribution by summing together said low vertical frequency contribution and said weighted high vertical frequency contribution, calculating a temporal contribution, and calculating said interpolated pixel by summing together weighted contributions from said total vertical contribution and said temporal contribution based on said weighting factors.
