Abstract
A video encoding device uses motion-compensated inter-frame prediction by dividing an image into blocks, each block a predetermined size, designating a first component value of a plurality of component values of a motion vector (MV) between an encoding target block and a neighboring block, designating a second component value, and encoding each first and second component values; a first component encoding means encodes a difference value of a first component and a second component encoding means, which obtains a probability of occurrence of a candidate value for the second component value of the MV of the encoding target block, based on a difference value between the first component value of the neighboring block MV and the first component value of the encoding target block MV and the second component value of the neighboring block MV, specifies a codeword of the second component value, encoding it based on the occurrence probability.
