Abstract

Un metodo para controlar la nitidez de la imagen en un aparato de despliegue de imagen que opera para desplegar una primera (Ymain) y una segunda (Ypip) senales de imagen en forma simultanea. El metodo comprende los pasos de: combinar la primera senal de imagen (Ymain) y una segunda senal (Ypip) de imagen para formar una senal (301) de despliegue simultaneo; generar una senal SVM para la mejora de imagen de despliegue de conformidad con la senal de despliegue simultaneo; controlar en forma dinamica una amplitud de la senal (300) SVM de acuerdo con la presencia de una de la primera (Ymain) y la segunda (Ypip) senales de imagen, que forman la senal (301) de despliegue de imagen; activar una bobina SVM con la senal SVM de amplitud controlada en forma dinamica para mejorar los bordes de imagen desplegados por el aparato de despliegue de video de conformidad con una de la primera (Ymain) y la segunda (Ypip) senales de imagen.
