Abstract
UN SISTEMA DE TELEVISION QUE INCLUYE UN EQUIPO LIMITADOR DEL CINESCOPIO EN FUNCION DE LA INTENSIDAD DEL HAZ QUE FUNCIONA PARA REDUCIR EL CONTRASTE DE LA IMAGEN SIN AFECTAR AL BRILLO DE LA IMAGEN CUANDO LA INTENSIDAD DEL HAZ SOBREPASA UN PRIMER VALOR UMBRAL. SIN EMBARGO, SI EL AJUSTE DE CONTROL DEL BRILLO REALIZADO POR EL USUARIO SOBREPASA EL NIVEL DE CONTROL DEL BRILLO NOMINAL (REGISTRO MEDIO), EL BRILLO DE LA IMAGEN SE REDUCE CUANDO LA INTENSIDAD DEL HAZ SOBREPASA UN SEGUNDO VALOR UMBRAL QUE PUEDE SER IGUAL O MAYOR QUE EL PRIMERO. EL BRILLO DE LA IMAGEN SE REDUCE SOLO HASTA QUE EL BRILLO DE LA IMAGEN SE ENCUENTRA DENTRO DE UN PEQUEÑO MARGEN DEL NIVEL DE BRILLO DE LA IMAGEN NOMINAL. CUALQUIER LIMITACION ADICIONAL DE LA INTENSIDAD DEL HAZ, PARA POR EJEMPLO ELIMINAR LAS CONDICIONES DE FUNCIONAMIENTO ANORMALES DEL SISTEMA DE TELEVISION, SE LLEVA A CABO A BASE DE SEGUIR REDUCIENDO EL BRILLO.
