Abstract

APARELHO E MéTODO DE PROCESSAMENTO DE QUADRO, PROGRAMA, E, APARELHO DE GERAçãO DE IMAGEM. é possível transferir dados de uma unidade de processamento de imagem para uma unidade de codificação sem usar uma memória externa para realizar um processamento em alta velocidade por transmissão interna tendo uma banda mais larga do que a memória interna. Uma imagem inteira (41) de uma imagem original é dividida em seis blocos de (64 x 4) pixéis. Um processo de ampliação é executado para cada bloco. Dados de blocos são lidos na ordem do número designado tal como 1, 2, 3... O primeiro bloco é processado por uma unidade de modificação de tamanho para gerar dados de imagem em um bloco (42) de (128 x 8) pixéis. A unidade de macroblocos (43) de (16 x 8) pixéis é lida dos dados de imagem (42) e codificada para obter dados de JPEG (44). Uma unidade de rearranjo de código re-arranja a ordem de dados de JPEG (46) na unidade de bloco, de modo a gerar dados de JPEG (48). Quando dados de JPEG (48) nesta ordem é codificado, é possível obter uma imagem decodificada (49) cuja ordem de bloco coincide com a área (41) da imagem original.
