摘要
介绍了用滤光片实现彩色微光电视系统的基本原理和方法,分析了加入滤光片前后图像的信噪比变化,认为合理选择滤光片可使彩色微光电视系统在一定程度上满足正常观察所需要的信噪比.
The basic principle and method of realizing the color LLLTV (low light level television) system with the help of light filter are introduced. The change of SNR (signal to noise ratio) of image before and after adding the light filter is analyzed. It is considered that SNR can be appropriate for normal observation of color LLLTV system to a certain extent by reasonable selection of light filter.
