Abstract

Un aparato para corregir unidades elementales de información (pixeles), el cual corrige el valor de un pixel de entrada utilizando un valor corregidopredeterminado de su correspondiente espejo accionado en un conjunto de M x N espejos accionados,comprendiendo el aparato un primer corrector para lacorrección gama del valor del pixel de entrada; una memoria para el almacenaje de un predeterminado juego de valores corregidos para dichos M x N espejosaccionados; un generador de información de ubicación para generar información de ubicación que representa la ubicación del pixel de entrada; un circuito,sensible a la información de ubicación generada para el pixel de entrada, para recuperar un valor corregido predeterminado desde los valores corregidos dedicho juego predeterminado que está almacenado; y un segundo corrector para corregir el valor gama-corregido del pixel de entrada utilizando el valorcorregido recuperado para de este modo proveer un valor corregido de pixel de salida.
