Abstract

"FAIXA DINâMICA E INTENSIFICAçãO DE CONTRASTE PARA MEIO DE EXIBIçãO MICRO". A invenção refere-se a um sistema de válvula de iluminação que intensifica a razão de contraste para imagens de vídeo clara e escura e reduz artefatos de contorno. O sistema de válvula de iluminação compreende um dispositivo de seleção de cor configurado para atenuar, temporalmente, faixas de luz de cores componentes para correspondência com um sinal de entrada de vídeo. Um primeiro dissociador do feixe de polarização configurado para polarizar as faixas de cores componentes em componentes opostamente polarizados, e o meio de exibição micro configurado para receber pelo menos um dos componentes opostamente polarizados para a formação de uma matriz de luz projetada.
