Abstract

resumo patente de invenção: "métodos, aparelhos e programas para codificar e decodificar imagem". a presente invenção refere-se a comparação com a codificação de imagem intradividida convencional, a deterioração na eficiência de codificação é suprimida e a complexidade computacional de codificação e a complexidade computacional de decodificação são reduzidas. uma unidade de geração de imagem dividida divide uma imagem de alvo de codificação de entrada em blocos do mesmo tamanho e gera imagens divididas que têm o mesmo tamanho mediante a coleta de pixels com a mesma posição relativa dentro de cada bloco. uma unidade de processamento de codificação de imagem intradividida executa a codificação de imagem intradividida em parte das imagens divididas. uma unidade de processamento de codificação de imagem interdividida executa a codificação de imagem interdividida com o uso de outra imagem dividida codificada como uma imagem de referência. quando há uma pluralidade de candidatos para a imagem de referência, uma unidade de cálculo de direção de correlação obtém uma combinação na qual uma correlação de um pixel em uma imagem original é alta entre as combinações de imagens divididas codificadas e suas imagens de referência.
