MOTION COMPENSATION METHOD, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a motion compensation method by which access to a reference memory is reduced.

SOLUTION: An image encoding apparatus 300 is provided with a motion vector detecting part 302 for selecting a motion vector detecting method for a motion compensation target block in accordance with a motion vector of a block positioned in the corner of a decoded macro block in a block group comprising the decoded macro block corresponding to a decoding target macro block, and for detecting a motion vector with the selected method, and a motion compensation encoding part 303 for producing a predictive image of the motion compensation target block on the basis of the detected motion vector.
