使用方法

这张测试卡用来评估锐度和波形失真。

你可以进一步的查看游艇的背面、桅杆、绳索、建筑物和树叶的清晰度。

游艇的长和短桅杆是用来评估电视屏幕上的重影、定位转移和亮度信号波形失真的。（i.e.linking）

通过桅杆和前游艇的边缘，你可以观察是否走样发生。远处的树木是用来检查黑暗部分色调再现性。

How to use

The image is suitable to evaluate sharpness and waveform distortion. 

You can check sharpness with yachts on the further back, masts, ropes, buildings, and leaves.

The tall and short masts of yachts are useful to find ghost, registration shifting and waveform distortion (i.e.linking) of brightness signal. By masts and edges of front yacht, you can observe whether aliasing happens. Far trees are useful to check tone reproduction of dark part.
