摘要
本文介绍一套彩色显像管色纯自动测量系统 ,通过分析辉度采样灵敏度 ,提出了线性区采样、二分法测量的算法。本系统由计算机作为控制核心 ,通过 DPMI实现了 Windows下的实时测量。作为一套自动测量系统 ,可极大提高彩色显像管色纯测量的效率。
An automatic measuring system for CPT purity is presented in this paper. By analyzing luminosity sampling sensitivity, we proposed the linear section sampling and the dichotomy measurement methods. The control center of this system is a computer, and the real time measurement in WINDOWS is implemented by DPMI. As an automatic system, it can greatly enhance the efficiency of CPT purity measurement.
