摘要

PROBLEM TO BE SOLVED: To provide a prediction vector generating method giving superior encoding efficiency.

SOLUTION: The prediction vector generating method of reference information such as a motion vector and a parallax vector, which are used for dividing an objective image into blocks and encoding or decoding them, includes a prediction vector generation step for generating the prediction vector of the objective block by using information showing a distance corresponding to the objective image and reference information of the block adjacent to the objective block.
