Abstract

Un aparato de correccion de datos de pixel, que corrige el valor de un pixel de entrada utilizando un valor corregido predeterminado de su espejo accionado correspondiente de una disposicion de espejos accionados MxN, comprende un primer corrector para corregir en gama el valor de pixel del entrada; una memoria para almacenar un juego predeterminado de valores corregidos para los espejos accionados MxN; un generador de datos de direccion para generar datos de direccion que representan la ubicacion del pixel de entrada; un circuito que responde a los datos de direccion generados para el pixel de entrada, para recuperar un valor corregido predeterminado de los valores corregidos del juego predeterminado almacenado; y un segundo corrector para corregir el valor corregido en gama del pixel de entrada usando el valor corregido recuperado, para proporcionar de esta manera un valor de pixel de salida corregido.
