Motion compensated video signal processing

摘要

Motion compensated video signal processing apparatus comprises means for generating a plurality of motion vectors to represent image motion between a pair of input images of an input video signal; means for testing a group of the motion vectors to select a motion vector from the group for use in interpolation of an output pixel of an output image; and a motion compensated interpolator for interpolating the output pixel from a pair of input images of the input video signal using the selected motion vector; the means for testing comprising: ```image enhancement means, Figure 13, for enhancing the image content of at least test blocks of the input images pointed to by a motion vector under test; ```means for detecting the degree of correlation between the image-enhanced test blocks; and ```means for selecting a motion vector having the highest degree of correlation between the respective image-enhanced test blocks.
