Abstract
The invention provides a motion vector searcher which includes an inter-block difference arithmetic operation section for calculating and outputting difference amounts between an original image MB and a plurality of search MBs, an additional amount arithmetic operation section for outputting a correction difference amount obtained by adding an additional amount, which relies upon a horizontal component and a vertical component of each of the motion vectors and a state of coding, to each of the difference amounts and for outputting a motion vector based on the motion vector, and a motion vector determination section for determining an optimum motion vector which exhibits the highest one of correlation degrees between the original image MB and the search MBs. With this arrangement, reduction of the information amount of motion vectors is achieved when the compression ratio is high and the transmission rate is low.
