| 摘要 |
Motion compensated video signal processing apparatus, in which motion vectors are generated to represent image motion between a pair of input images of an input video signal, comprises means for comparing search blocks within one of the pair of input images with respective search areas, comprising a plurality of blocks, in the other of the pair of input images, to generate a first plurality of original correlation surfaces, each comprising an array of correlation values representing correlation between the respective search block and search area; means for generating a second plurality of interpolated correlation surfaces by interpolation from the original correlation surfaces; and means for generating a respective motion vector from each interpolated correlation surface, in dependence on a point of maximum correlation in that interpolated correlation surface. |
