Abstract

APARATO PARA EL CONTROL DE SEGUIMIENTO DE LUMINOSIDAD Y DE SELECCION DE COLOR PARA UN SISTEMA DE PRESENTACION POR TUBO DE RAYOS CATODICOS.CONSTA DE UN TUBO DE RAYOS CATODICOS (20) CON DOS CAN/ONES DE COLOR; UN CONTROL (35) DE LUMINOSIDAD DE REFERENCIA DE LA IMAGEN; UN DESCODIFICADOR (30) DE COLOR DE VIDEO; UN AMPLIFICADOR ANALOGICO (31, 32, 33) QUE APLICA UN FACTOR DE CORRECCION; Y UN AMPLIFICADOR LINEAL (24, 25, 26) QUE TIENE UNA GANANCIA VARIABLE. EL CATODO DE UN CAN/ON DE COLOR ES ACTIVADO DE MANERA PROPORCIONAL A LA LUMINOSIDAD PREDETERMINADA CORRESPONDIENTE A LA IMAGEN Y A LA PRESENTACION EN COLORES PREDETERMINADA, PROPORCIONANDO UNA CORRECCION DE COLOR PARA LA RESPUESTA DE LA EMISIVIDAD DEL FOSFORO Y EL SEGUIMIENTO DE COLOR ENTRE CAN/ONES, A MEDIDA QUE SE HACE VARIAR EL NIVEL DE REFERENCIA DE LUMINOSIDAD.
