摘　　要：本文简要介绍了彩色电视机倍(变)频扫描技术,提出了各种倍(变)频扫描技术方案的比较和分析方法。通过分析计算得出,应用倍(变)频扫描技术能有效消除行间闪烁和图像大面积闪烁,但不可能改变摄像端的分解力或信号源的内容。In this paper, the color TV variable frequency scanning technology is introduced, at the same time, the schemes and analysis ways of various color TV variable frequency scanning technology are put forward. It was found that the variable frequency scanning technology can effectively clean inter- line flicker and picture flicker, but can not change the resolution of camera term and the part of signal source by the analysis.

关 键 词：行扫描频率 视频信号带宽 水平清晰度 垂直清晰度
