Abstract

resumo aparelho e método para gerar um sinal de imagem, aparelho e método para processar um sinal de imagem e sinal de imagem um aparelho gera um sinal de imagem no qual os pixels são codificados em termos de n bits que codificam pelo menos uma luma por pixel. um receptor (201) obtém valores de pixel de alta variação dinâmica, de acordo com uma primeira representação de cor, termos de m bits de entrada de entrada. um primeiro gerador (203) inclui os valores de pixel de alta variação dinâmica no sinal de imagem nos termos de n bits, de acordo com uma segunda representação de cor. um segundo gerador (205) inclui, no sinal de imagem, um indicador de que os valores de pixel de alta variação dinâmica são codificados. em alguns exemplos, os valores de pixel de alta variação dinâmica podem ser providos em um segmento que pode conter alternativamente valores de pixel de alta ou baixa variação dinâmica, e o indicador pode indicar qual tipo de dados é incluído. a abordagem pode, por exemplo, facilitar a introdução de capacidade de alta variação dinâmica, por exemplo, em sistemas hdmi. 1/1
