Abstract
Un sistema de pantalla (500) procesa una señal de entrada para generar una imagen. La señal de entrada incluye cuadro de datos sucesivos que definen líneas que incluyen valores de imagen y tienen una direccion de línea. Una pantalla (100) para mostrar la imagen tiene segundos electrodos (104) que estén en una direccion que corresponde a la direccion de línea. Una memoria de video (64) que almacena un cuadro de datos incluye un regulador de línea (602) y un regulador de cuadro (608). Un controlador (622) controla el almacenamiento del cuadro de datos en la memoria de video (640) y genera una funcion independiente de imagen predeterminada durante un segmento de tiempo. Una máquina de calcular (632) computa una señal de salida dependiente de imagen durante el segmento de tiempo que tiene valores. Cada uno de los valores se determina a partir de la funcion independiente de imagen predeterminada y de valores de imagen de una de las líneas almacenadas en la memoria de video.
