简介说明

高精细度透过型彩色测试卡使用方法

这个测试卡被用于检查整个图像的纹理。你应该把注意力集中在面包、可乐饼或餐巾布中,观察水果和火腿片的锐度,检查包装纸盒顶部表面的亮度以及椰菜花的细节,以此来评价电视最高白平衡再现性。

在板上的植物的主干和图像的色调是起到调整画面的黑暗作用的。在图像的左侧的堆积餐巾纸,因为图像的部分包括横向楔700~800TV线间闪烁很可能在这里变得明显就给出了的垂直分辨率的指示。瓜果堆放的模块用来显示匹配状态是否出现图像匹配现象以及相关的事情隔行扫描问题。鸡蛋是有效找出重影和反射造成的匹配的延迟线问题,还有红色康乃馨和蓝色罐是合适的检查分辨率的退化和波形畸变的问题,当色差信号是限带,在饱和区其中发生。在饱和区域内发生的色差信号带宽受限问题。

This image is used for checking the texture of the entire image. You should focus attention on the bread rolls, the croquettes or the fabric of napkins,observe sharpness of fruits and slices of ham, check brightness of the top surface of the box in wrapping paper, and evaluate reproducibility of details with cauliflower at highest white level. The trunk of the plant and the shades of plates in the image are useful to adjust the darkness of a screen. 

The piled paper napkins on the left of the image provide an indication of vertical resolution because the part of the image consists of 700~800TVof horizontal wedges and inter-line flicker is likely to become obvious here. The images of pattern of melon and piled plates show whether pairing state happens and things related to interlace scan. The egg is effective to find ghost and reflection caused by matching problem of delay line, also red carnations and the blue can are suitable to check resolution-degradation and waveform distortion, which happen when color-difference signal is band limited, in saturation area.

This chart is only available for transparent type.
