Abstract
A method for detecting motion vectors comprises the steps of (a) producing a plurality of differential search blocks, wherein each differential search block includes differential pixels defined by differences between luminance levels of the pixels in a search block and a mean luminance level of the pixels in the search block, (b) producing a multiplicity of differential candidate blocks, wherein each differential candidate block includes differential pixels defined by differences between luminance levels of the pixels in a candidate block and a mean luminance level of the pixels in the candidate block, (c) motion-estimating a search block with respect to each of the candidate blocks associated with a corresponding search region to produce displacement vectors corresponding thereto and motion-estimating a differential search block with respect to each of the differential candidate blocks associated with a corresponding search region to produce error functions corresponding thereto, and (d) choosing a minimum error function to define a displacement vector corresponding to the minimum error function as a motion vector for the search block.
