Abstract
(EN)
The invention relates to an image encoding device, an image encoding method, an image decoding device, and an image decoding method. The image encoding device is provided with: an encoded information storage unit that fills all history candidates in a history predictive motion vector candidate list with at least predetermined motion vectors and reference indexes; a merge candidate list generation unit that generates a merge candidate list including, as merge candidates, at least motion vectors and reference indexes of blocks adjacent to a to-be-encoded block; a history merge candidate addition unit that adds history candidates included in the history predictive motion vector candidate list to the merge candidate list as merge candidates so as to output a second merge candidate list; and a merge candidate selection unit that selects, from the second merge candidate list, merge candidates as selected merge candidates. The encoded information storage unit adds the selected merge candidates to the history predictive motion vector candidate list as the history candidates so as to output the history predictive motion vector candidate list.
