SineImage条块测试卡简介

　　分辨率测试卡Sine-Image条块测试卡为了检测电视摄像机的中级和深度频率的传输特性而设计的。在测试卡上部4条不同长度的黑色水平条块被分布白色背景上。下半部是上面的一个镜像，但是是白色条块分布在黑色背景上。在图像的中位置有一个狭小的黑色和白色垂直直条。这些条块各自产生脉冲信号大约为2µs,5µs,12µs和32µs。

　　Introduction to SineImage Bar Test

　　The Sine-Image bar test card is designed to detect the transmission characteristics of the intermediate and depth frequencies of the television camera. In the upper part of the test card, four different lengths of black horizontal bars are distributed on a white background. The lower half is a mirror image above, but the white bars are distributed on a black background. There is a small black and white vertical bar in the middle of the image. Each of these bars produces a pulse signal of approximately 2 μs, 5 μs, 12 μs, and 32 μs.
