Abstract
Perfeccionamientos en aparatos para controlar automáticamente la polarización de un cinescopio reproductor de imágenes de video, en un sistema para elaborar una señal de video representativa de imagen que tiene intervalos de imagen periódicamente cíclicos e intervalos de supresión, cuyo sistema comprende un cinescopio de reproducción de imágenes que tiene un cañón electrónico con electrodos de control de intensidad del cátodo y la rejilla, y medios para acoplar señales de video al cañón electrónico del cinescopio, un aparato para controlar automáticamente la polarización del nivel de supresión del cinescopio, caracterizados porque comprenden medios que proporcionan un voltaje de polarización de referencia al electrodo catódico por un trayecto de conducción de corriente catódica durante un intervalo de medición coincidente con una parte del intervalo de supresión , medios para proporcionar una señal auxiliar al electrodo de la rejilla durante una parate del intervalo de medición en un sentido para polarizar en directo el electrodo de la rejilla, medios de detección sensible a la tensión con una entrada acoplada al trayecto de conducción de corriente catódica y una salida, para proporcionar un voltaje de diferencia de salida proporcionar a la diferencia entre al corriente que fluye en el trayecto de la corriente catódica durante dicha parte del intervalo de medición en respuesta a la señal auxiliar, y la corriente que fluye en el trayecto de corriente catódica en otros momentos durante el intervalo de medición, y medios que responden al voltaje de diferencia para proporcionar una señal de control a los medios de acoplamiento de la señal de video, para modificar la polarización del cinescopio en la dirección necesaria para reducir la diferencia de voltaje a un nivel mínimo correspondiente a la condición de polarización deseada del cinescopio.
