如何使用

该测试卡用来评价色差信号的频带限制的分辨率和降解。砾石路径和石墙用来检查分辨率和清晰度。通过检查各种大大小小的郁金香来观察是否有色差信号的带宽限制降解。此外，郁金香花瓣适于检查的颜色和亮度的鲜艳度信号的相移的情况。

How to use

This image is useful to evaluate resolution and degradation with band-limitation of color-difference signal.The gravel paths and stone walls are suitable for checking resolution and sharpness. 

You can observe if there is degradation with band-limitation of color-difference signal by checking a variety of big and small tulips. In addition, tulip petals are suitable for checking vividness of colors and conditions of phase shifting of brightness signal.
