    摘要： A method of performing motion compensation includes identifying a set of candidate motion vectors for a block in an intermediate frame from a set of motion vectors from a previous and current frames, performing block-level analysis for each candidate motion vector, selecting an interpolation motion vector, and using the interpolation motion vector to interpolate the intermediate frame between the previous and current frames, wherein the number of intermediate frames depends upon a conversion to a faster frame rate. A method of determining background and foreground motion vectors for a block in an interpolated frame includes comparing a first motion vector that points to a previous frame to a second motion vector that points to a next frame to produce a difference, and designating one of the first and second motion vectors as a background motion vector and the other as a foreground motion vector depending upon the difference.
