Abstract

dispositivo de codificação de foto em movimento, método de codificação de foto em movimento e programa de codificação de foto em movimento, e dispositivo de decodificação de foto em movimento, método de decodificação de foto em movimento e programa de decodificação de foto em movimento. a presente invenção refere-se a uma unidade de geração de candidato de previsor de vetor de movimento (121 ) que faz uma previsão com base em um vetor de movimento de um dos blocos vizinhos codificados que são vizinhos a um bloco-alvo de codificação em espaço ou tempo e gera uma pluralidade de candidatos a previsores de vetor de movimento. uma unidade de remoção de candidato de previsor de vetor de movimento redundante (123) remove os candidatos a previsores de vetor de movimento que têm identidade dentre os candidatos a previsores de vetor de movimento previstos com base em um bloco vizinho codificado que é vizinho em espaço de uma lista de candidato de previsor de vetor de movimento em que p elo menos um é deixado. uma unidade de seleção de previsor de vetor de movimento (126) seleciona um previsor de vetor de movimento da pluralidade de candidatos a previsores de vetor de movimento. uma primeira unidade geradora de fluxo de bits (109) codifica informações que representam o previsor de vetor de movimento selecionado.
