摘要

This video encoding device (100) is provided with: a predicted motion vector candidate calculation unit (114) that calculates predicted motion vector candidates and the number of predictable candidates; an inter-prediction control unit (111) that selects the optimal predicted motion vector candidate; and a variable-length encoding unit (116) that sets the number of predictable candidates to the list size of predicted motion vector candidates, allocates a bit sequence that is in accordance with the list size of predicted motion vector candidates to a predicted motion vector index used in motion vector encoding, and performs variable-length encoding.
