Abstract

"MéTODO DE CODIFICAçãO DE IMAGEM E MéTODO DE DECODIFICAçãO DE IMAGEM". Método de codificação de imagens da presente invenção é um método de codificação de imagens de codificação de predição de uma imagem de entrada com referência às imagens armazenadas em um armazenamento temporário de imagens, decodificação da imagem de entrada codificada, julgamento se a imagem decodificada é ou não uma imagem para referência e se a imagem decodificada é ou não uma imagem para saída, que precisa ser armazenada até o momento de sua exibição e armazenamento, no armazenamento temporário de imagens, da imagem para referência e da imagem para saída com base no resultado da determinação.
