组成一个电视系统,摄象机作为信号源,它的图象质量,特别是清晰度,是个关键问题。而在摄象机日趋小型化的今天,由于摄象器件线象面的缩小,怎样提高摄象机的清晰度更加重要。目前,日本2/3″管的摄象机,都已达到650TVL的水平。l/2″管的摄象机也已达到500TVL的水平。本文就2/3″管摄象机在设计和使用中,怎样提高清晰度,谈一些看法。
The composition of a television system, the camera as a signal source, its image quality, especially sharpness, is a key issue. In the increasingly miniaturized camera today, due to the narrow line of the camera device, how to improve the clarity of the camera is even more important. At present, Japan 2/3 “tube camera, have reached the level of 650TVL.l / 2” tube camera has also reached 500TVL level. This article on 2/3 "tube camera in the design and use, how to improve the clarity, to talk about some views.
