摘要

An inter-prediction information derivation unit (104) derives inter-prediction information candidates from inter-prediction information pertaining to a prediction block to be coded and coded prediction blocks which are contiguous to the prediction block to be coded within the same picture, and inter-prediction information pertaining to prediction blocks in a coded picture which is different from that of the prediction block to be coded. The inter-prediction information derivation unit (104) determines, among the derived inter-prediction information candidates, an inter-prediction information candidate to be used for the inter-prediction of the prediction block to be coded. A second coded bit sequence generation unit (110) encodes indices of the inter-prediction information candidates on the basis of the number of the inter-prediction information candidates.
