Abstract

LA INVENCION SE REFIERE A UN PROCESO DE CODIFICACION DE COLORES DE CARACTERES EN UN SISTEMA DE VIDEO QUE COMPRENDE UN GENERADOR DE CARACTERES, COMPRENDIENDO LOS MODELOS DE ESTOS CARACTERES AL MENOS DOS ZONAS, CARACTERIZANDOSE DICHO PROCESO EN QUE UN ATRIBUTO COLOR CUYO NIVEL ES SUPERIOR AL NIVEL DE PAGINA SE UTILIZA PARA DETERMINAR EL COLOR DE TODAS LAS ZONAS DE TODOS LOS CARACTERES QUE CORRESPONDEN A ESTE NIVEL, SIENDO LOS VALORES DE LUMINOSIDAD ELEGIDOS PARA CADA UNA DE LAS ZONAS DE CARACTERES TALES QUE, PARA UN CARACTER DADO, ESTAS ZONAS PUEDAN DISTINGUIRSE CUANDO TIENE EL MISMO COLOR. LA INVENCION SE APLICA EN EL CAMPO DE LA TELEVISION.
