Abstract

MÉTODO E APARELHO PARA PROCESSAMENTO ELETRâNICO DE IMAGEM A CORES, VISOR ELETRâNICO, UNIDADE DE ARMAZENAMENTO ELETRâNICA, UNIDADE DE REDE, CÂMERA DE QUADRO PARADO OU DE VÍDEO, PRODUTO DE PROGRAMA DE COMPUTAÇçO, E, REPRESENTAÇçO DE IMAGEM ELETRâNICA ESPECIALMENTE ADAPTADA. O método moderno de processamento eletrônico de imagem a cores inclui: introduzir uma imagem; obter uma cor (A) baseado em cores presentes em pelo menos uma primeira parte da imagem; e mudar um correlato de saturação (S2) definido com respeito à cor (A) para pelo menos uma segunda parte da imagem. Isto permite modificação de saturação de melhor qualidade em um número maior de possíveis imagens de entrada.
