Abstract
um método para o processamento de um sinal de vídeo de entrada destina-se a um primeiro monitor para produzir um sinal de saída apropriado para um segundo monitor que compreende a conversão utilizando uma ou mais funções de transferência. as funções de transferência são dispostas de modo a proporcionar valores de luz relativos à cena para, em seguida, retirar ou aplicar o propósito de processamento. a tentativa de processamento sendo o propósito de processamento do sinal de entrada ou para o propósito do processamento do sinal de saída. a remoção ou aplicação do método de renderização altera a luminância. significativamente, a conversão é disposta de modo a alterar a luminância, mas não os componentes de cor de modo que a cor não é alterada.
