Abstract

APARATO DE VISUALIZACION DE IMAGENES PREVISTO PARA IMAGENES EN FORMATO 16/9, DOTADO DE MEDIOS ACCESIBLES AL USUARIO PARA EL AJUSTE SIMULTANEO DE LA LONGITUD DE LAS LINEAS Y DE LA SEPARACION VERTICAL DE LAS LINEAS. PARA RECIBIR IMAGENES DE FORMATO 4/3, LOS DOS MEDIOS DE AJUSTE ESTAN ACOPLADOS DE TAL MANERA QUE DISMINUYE LA LONGITUD DE LAS LINEAS DE LA IMAGEN VISUALIZADA 2, 20) CUANDO LA SEPARACION VERTICAL DE LAS LINEAS ES NORMAL O QUE LA LONGITUD DE LAS LINEAS DE LA IMAGEN VISUALIZADA ES NORMAL CUANDO AUMENTA LA SEPARACION VERTICAL DE LAS LINEAS (3, 6). ADEMAS DICHOS MEDIOS DE AJUSTE SON DE UN TIPO CON VARIACION CONTINUA, Y EL ACCESO DEL USUARIO A DICHOS MEDIOS DE AJUSTE SE HACE POR UN MANDO A DISTANCIA.
