Abstract
QUE COMPRENDE: A) MEDIOS PARA CORRECCION GAMMA DEL VALOR DEL PIXEL DE INGRESO; B) MEDIOS PARA ALMACENAR UN CONJUNTO PREDETERMINADO DE VALORES CORREGIDOS PARA DICHOS ESPEJOS ACCIONADOS; C) MEDIOS PARA GENERAR DATOS DE DIRECCION QUE REPRESENTAN LA UBICACION DEL PIXEL DE INGRESO; D) MEDIOS CAPACES DE RESPONDER A LOS DATOS DE DIRECCION GENERADOS PARA EL PIXEL DE INGRESO, PARA RECUPERAR UN VALOR CORREGIDO PREDETERMINADO DE LOS VALORES CORREGIDOS DEL CONJUNTO PREDETERMINADO ALMACENADO; Y E) MEDIOS PARA CORREGIR EL VALOR CORREGIDO GAMMA DEL PIXEL DE INGRESO UTILIZANDO EL VALOR CORREGIDO RECUPERADO PARA DE ESTA FORMA PROPORCIONAR UN VALOR DE PIXEL DE SALIDA CORREGIDO, CADA UNO DE LOS VALORES CORREGIDOS CONSTA DE 8 BITS, Y UN BIT DE MAYOR IMPORTANCIA EN EL VALOR CORREGIDO DE 8 BITS ES UN BIT QUE DENOTA SI UN ESPEJO ACCIONADO CORRESPONDIENTE AL PIXEL DE INGRESO ESTA INCLINADO EN UNA DIRECCION POSITIVA O EN UNA DIRECCION NEGATIVA. ADICIONALMENTE CONSTA DE MEDIOS PARA LIMITAR EL VALOR CORREGIDO DE PIXEL DE SALIDA SI NO ESTA DENTRO DE UN RANGO PREDETERMINADO DE VALOR DE PIXEL. PROVEE IMAGENES DE ALTA CALIDAD EN UNA GRAN ESCALA A TRAVES DE UNA DISPOSICION DE PROYECCION OPTICA
