Abstract

"COMPENSAçãO DE LUZ GRADUADA PARA REDUçãO DE ARTEFATOS EM MOVIMENTO". Um sistema de exibição colorida seqüencial (10) inclui um alterador de cor (14, 16) que faz com que cada uma de um conjunto de cores primárias apareça em um reprodutor de imagens que ilumina cada um de uma série de pixels em uma tela de exibição. Um controlador (30, 31) aplica sinais de controle ao reprodutor de imagens para controle do brilho de pixel para cada cor. Cada vez que o alterador de cor transita de uma cor primária para outra, ocorre uma graduação (18), e a luz misturada de duas cores iluminará o reprodutor de imagens. O controlador faz com que o reprodutor de imagens utilize tal luz graduada quando o nível de brilho para cada cor para o pixel afim ultrapassa um limite prescrito. Quando faz uso da luz graduada, o controlador altera o sinal de controle de modo a diminuir o brilho de pelo menos uma cor primária em proximidade temporal substancial com relação à ocorrência da graduação, com a finalidade de compensar o aumento no brilho causado pela utilização da luz durante a graduação.
