一、寻找测试清晰度的工具 AV爱好者对自己的电视机能达到多少线的清晰度总是很关心的,他们不但在选购电视机时希望能测量一下所选电视机能达到什么样的清晰度,而且在使用过程中也免不了要进行一些清晰度测量。比如,为了比较从RF射频端子、普通Video端子、S端子、分量YCbCr(YPbPr)端子或RGB端子输入的视频信号,在同一台电视机上的清晰度效果有何不同,就要求有一种简单有效的清晰度测试工具来解决。
First, find the tool for testing clarity AV enthusiasts on how much their own television can achieve the clarity of the line is always very concerned about, not only in the purchase of television they hope to measure the selected TV can achieve what kind of clarity , But also in the process of using inevitable to make some clarity measurements. For example, in order to compare the video signals input from RF RF terminals, normal video terminals, S terminals, component YCbCr (YPbPr) terminals or RGB terminals, the difference in sharpness on the same TV sets requires a simple and effective Clarity test tool to solve.
