Abstract
um conjunto de metadados existente que é específico para um modelo de transformação de volume de cor é transformado em um conjunto de metadados que é específico para um modelo de transformação de volume de cor distintivamente diferente. por exemplo, metadados de conteúdo de origem para um primeiro modelo de transformação de volume de cor são recebidos. estes metadados de origem determinam uma transformação de volume de cor específica, tal como uma curva de mapa de tom sigmoidal. a transformação de volume de cor específica é mapeada para uma transformação de volume de cor de um segundo modelo de transformação de volume de cor, por exemplo, uma curva de mapa de tom de bézier. mapeamento pode ser uma melhor curva de ajuste, ou uma aproximação razoável. mapeamento resulta em valores de metadados usados para o segundo modelo de transformação de volume de cor (por exemplo, um ou mais pontos de joelho da curva de bézier e âncoras). portanto, os dispositivos configurados para o segundo modelo de transformação de volume de cor podem razoavelmente renderizar conteúdo de origem de acordo com os metadados de conteúdo de origem recebidos do primeiro modelo de volume de processamento de cor.
