Abstract
Herein disclosed is a motion vector searching apparatus for searching motion vectors indicative of visual motion between a current picture consisting of current picture blocks and a reference picture consisting of search windows each including a set of reference picture blocks by calculating a set of distortion values and detecting the minimum value from the distortion values. The motion vector searching apparatus comprises means for outputting current block data, means for outputting search window data, and data registering means for registering the search window data in a searching region covering first and second pixels. The data registering means has first transmission registers for initially registering part of the search window data corresponding to the first pixels and second transmission registers for initially registering the remaining part of the search window data corresponding to the second pixels. The motion vector searching apparatus further comprises transmission controlling means for having the search window data transmitted in a predetermined direction from the second transmission registers to the first transmission registers while the search window data is transmi…
