MOVING IMAGE ENCODING APPARATUS AND MOVING IMAGE ENCODING METHOD

摘要

An encoding unit that encodes a moving image using inter-frame motion prediction segments each frame into a plurality of segmented regions (302), and determines a region of interest from a frame to be decoded (317). The encoding unit (310) retrieves a pixel set, from the region of interest of the previous or succeeding frame, having high correlation to each segmented region of the frame to be encoded, calculates the difference between the data of each segmented region and data of the retrieved pixel set, and outputs difference data (314). Then, the encoding unit encodes the difference data (303, 306).
