Abstract

método e sistema para correção de cor de displays com diferentes gamas de cores são fornecidos um método e sistema para correção de cor em displays com diferentes gamas de cores. o método inclui executar correção de cor em conteúdo de imagem de fonte, utilizando pelo menos um entre um display do tipo não de referência tendo uma gama de cores não de referência e um display do tipo de referência tendo uma gama de cores de referência. a etapa de execução inclui masterizar (530) o conteúdo de imagem de fonte para fornecer conteúdo de imagem com correção de cor masterizado para exibição nos displays do tipo de não referência tendo uma gama de cores de não referência. a etapa de execução inclui ainda gerar (586) metadados para um mapeamento de gama de cores inverso subsequente que transforma em cor o conteúdo de imagem com correção de cor masterizado para exibição nos displays do tipo de não referência tendo uma gama de cores de não referência. o mapeamento de gama de cores inverso subsequente é uma operação inversa de um mapeamento de gama de cores aplicado durante a correção de cor para obter o conteúdo de imagem com corréção de cor masterizado para exibição nos displays do tipo de referência tendo a gama de cores de referência. o conteúdo de imagem de fonte é masterizado somente para os displays do tipo de referência tendo a gama de core de referência.
