Study on Principle and Technology of Two Colour False Colour Low Light Level TV System

该文对双谱假彩色微光电视系统的原理进行论述，探讨了实现双谱假彩色微光电视系统的有关技术。双谱探测技术是这种彩色微光技术的重要组成部分和理论基础，其关键就是根据夜天光辐射以及景物夜晚光谱反射特性，选择合适的对比度转换点位置，分割有效光谱为两部分；彩色最佳逼近技术，就是研究如何选择这一对比度转换点位置和适当算法，才能使双谱彩色微光图象具有最佳的分辨率和图象探测率；最后给出系统实现方法、实验结果及分析。

This thesis puts emphasis on study on principle and technology of two colour false colour low light level TV system, pursuing the related techniques of realizing. Two colour detection technology is the important part and theoretical basis of this colour low light level technology. Its crux is the choice of suitable contrast turning position and the division of effective spectrum of night sky and reflection property of night scenery. The best colour approaching technology is about how to choose this contrast turning position and suitable algorithm to make the best resolution and detection of the two colour false colour low light level image.In the end, the realizing method, experiment results and analyses are given.
