Abstract

UN SISTEMA DE PANTALLAS DE VIDEO, QUE CONSTA DE UNA PANTALLA DE VIDEO QUE TIENE UNA PRIMERA RELACION DE REPRESENTACION DE FORMATO. UN CIRCUITO DE ALTURA DE IMAGENES (1010) DETERMINA LA ALTURA DE LA IMAGEN ACTIVA A PARTIR DE UNA SEÑAL DE VIDEO DE ENTRADA QUE TIENE UNA SEGUNDA RELACION DE REPRESENTACION DE FORMATO. UN CIRCUITO DETECTOR (1030) QUE IDENTIFICA FORMATOS TIPO BUZON DE CORREOS RESPONDE A LA ALTURA DE LA IMAGEN ACTIVA DE LA SEÑAL Y DETERMINA UNA RELACION DE REPRESENTACION DE FORMATO DE LA IMAGEN CON FORMATO TIPO BUZON DE CORREOS. SE PUEDE ACTIVAR UN CIRCUITO DE AMPLIACION (1032) EN UN PRIMER MODO PARA QUE AMPLIAR EL TAMAÑO DE LA IMAGEN DE MODO QUE LLENE SUSTANCIALMENTE TODA LA PANTALLA Y SE PUEDE ACTIVAR EN UN SEGUNDO MODO PARA ALARGAR EL TAMAÑO DE LA IMAGEN DE MODO QUE LLENE SUSTANCIALMENTE LA PANTALLA VERTICALMENTE. UN CIRCUITO DE REPRESENTACION PANORAMICA VERTICAL (1034) CENTRA LA IMAGEN. EL DETECTOR PUEDE IDENTIFICAR LA RELACION DE VISUALIZACION DE FORMATO DE LA IMAGEN CON FORMATO TIPO BUZON DE CORREOS. SE PUEDE CONTROLAR EL TAMAÑO VERTICAL DE UN SISTEMA DE DEFLEXION (50) MEDIANTE UNA VELOCIDAD DE EXPLORACION VERTICAL VARIABLE, EL TAMAÑO HORIZONTAL MEDIANTE UNA EXPANSION Y COMPRENSION HORIZONTAL VARIABLE Y LA POSICION PANORAMICA VARIANDO LA FASE DE LA REPOSICION VERTICAL.
