Abstract

APARELHO E MéTODO DE PROCESSAMENTO DE IMAGEM. Um dispositivo de geração de padrão básico (81) gera um padrão básico de porção de filme (86) tendo um histograma de ruído randómico quase idêntico a informação de padrão básico de porção de filme (53). O padrão básico de porção de filme (86) tem ¢64 x 64! pixéis, dos quais uma área de ¢16 x 16! pixéis é cortada e fornecida a um multiplicador (84). Informação de intensidade (88) é gerado de acordo com a informação de intensidade de porção de filme (54) criada no lado de codificação e um valor médio (87) de valor de pixel da área de ¢16 x 16! pixéis de informação de imagem decodificada (42). De acordo com esta informação de intensidade (88), intensidade do padrão básico (86) é ajustado. A imagem de granulação de filme (89) que foi sujeitada a ajustes de intensidade é adicionada na unidade de pixel da área de ¢16 x 16! pixéis da informação de imagem decodificada (42) por uma somador (85).
