Abstract

"APARELHO E PROCESSO PARA PROCESSAMENTO DE SINAL DE CORES". A presente invenção refere-se a um aparelho para processamento de sinais de cor que calcula uma gama de cores alvo que inclui valores de sinal de cor de cada pixel em um vídeo de entrada, e calcula cores primárias alvo correspondentes à gama de cores alvo calculada. O aparelho para processamento de sinais de cor produz as cores primárias alvo calculadas por mesclar cores primárias em uma gama de cores de entrada do vídeo de entrada e converter e emitir os valores de sinal de cor de cada pixel do vídeo de entrada para casar a gama de cores alvo calculada definida pelas cores primárias alvo calculadas. Uma vez que é possível transformar adaptativamente a gama de cores de entrada do vídeo de entrada, o vídeo de entrada que é reproduzido tem uma quantidade de luz aumentada e um contraste otimizado.
