Abstract
Un aparato de corrección de datos de píxel, el cual corrige el valor de un píxel de entrada usando un valor corregido predeterminado de su correspondiente espejo accionado en un conjunto de MxN espejos accionados, comprendiendo un primer corrector para corrección de gama en valor del píxel de entrada, una memoria para almacenar un juego de valores corregidos predeterminados para dichos espejos accionados MxN, un generador de direcciones para generar direcciones que representan la ubicación del píxel de entrada, un circuito, que responde a las direcciones generadas para el píxel de entrada, para recuperar un valor corregido predeterminado del juego almacenado de valores corregidos predeterminados y un segundo corrector para corregir los valores de gama corregidos del píxel de entrada usando el valor corregido recuperado para, por ese medio, proveer un valor corregido para el píxel de salida.
