Abstract

La presente invencion se refiere a un dispositivo para la proyeccion digital de una imagen de video, usando la modulacion de division del tiempo. Este dispositivo esta disenado para proyectar una imagen de video durante un cuadro de video que comprende una pluralidad de subcampos consecutivos distribuidos dentro de al menos dos segmentos de tiempo identicos separados. De acuerdo con la invencion, los pixeles de la imagen de video cambian de estado al menos una vez durante cada segmento de tiempo, y la imagen de video que va a proyectarse es guardada en la memoria de imagen en la forma de informacion que identifica, para cada subcampo, a los pixeles que estan cambiando de estado.
