Abstract
A method for detecting motion vectors comprises the steps of (a) motion-estimating a search block with respect to each of the candidate blocks in a corresponding search region to produce displacement vectors and error functions corresponding thereto, each of the displacement vectors representing each of the displacements between pixels in the search block and their corresponding pixels in each of the candidate blocks, and the error functions being calculated based on differences between luminance levels of the pixels in the search block and those of their corresponding pixels in each of the candidate blocks, (b) calculating an error value based on each of the displacement vectors and each of the error functions corresponding thereto, and (c) choosing a minimum error value to define a displacement vector corresponding to the minimum error value as the motion vector for the search block.
