Abstract
SE PRESENTA UN DISPOSITIVO PARA REPRESENTAR CARACTERES Y / O GRAFICOS SOBRE UNA PANTALLA DE UN SISTEMA DE TELEVISION QUE INCLUYA UNA SECCION DE CONTROL DE BRILLO (23) PARA CONTROLAR EL NIVEL DE NEGRO DE LAS IMAGENES DE VIDEO, EL DISPOSITIVO INCLUYE UNA SECCION DE BORRADO DE CARACTERES (79) PARA BORRAR POR DETRAS DE LA IMAGEN DE VIDEO DE TAL FORMA QUE HAGA QUE LOS CARACTERES Y / O GRAFICOS SEAN MAS VISIBLES. LA SECCION DE BORRADO DE CARACTERES SE ACOPLA A LA SECCION DE CONTROL DE BRILLO PARA GENERAR UN NIVEL DE BORRADO DE CARACTER "ULTRANEGRO" QUE REALIZARA EL BARRIDO, PERO QUE ES ALGO MAYOR (EN LA DIRECCION DEL NEGRO) QUE EL NIVEL DE NEGRO PARA LA IMAGEN DE VIDEO.
