目标摄像电路中的关键问题

THE CRUX OF THE CIRCUIT OF VIDEOTAPED OBJECT

本文给出一个有特色的、成功的在目标摄像设备中最具重要性的视频放大电路.它具有可调节通频带的反馈线,方便作反杂波校正.又有可调电位的箝位电路切割、调正白色电平,有利于在不同照度时摄像改善目标图像.

This paper gives a successful and important special video amplification circuit which is applied to a appliance of videotaped object. There is feedback circuit shich is convenient for adjusting the band and compensating insertionloss. There is a constained voltage circuit, which can be modulated,to cut down and adjust the white level. It helps to improve the pictures videataped in different illumination.
