高精細(xì)度透過型彩色測試卡使用方法
這個測試卡被用于檢查整個圖像的紋理。你應(yīng)該把注意力集中在面包、可樂餅或餐巾布中，觀察水果和火腿片的銳度，檢查包裝紙盒頂部表面的亮度以及椰菜花的細(xì)節(jié)，以此來評價電視白平衡再現(xiàn)性。
在板上的植物的主干和圖像的色調(diào)是起到調(diào)整畫面的黑暗作用的。在圖像的左側(cè)的堆積餐巾紙，因?yàn)閳D像的部分包括橫向楔700~800TV和線間閃爍很可能在這里變得明顯就給出了的垂直分辨率的指示。瓜果堆放的模塊用來顯示匹配狀態(tài)是否出現(xiàn)圖像匹配現(xiàn)象以及相關(guān)的事情隔行掃描問題。雞蛋是有效找出重影和反射造成的匹配的延遲線問題，還有紅色康乃馨和藍(lán)色罐是合適的檢查分辨率的退化和波形畸變的問題，當(dāng)色差信號是限帶，在飽和區(qū)其中發(fā)生。在飽和區(qū)域內(nèi)發(fā)生的色差信號帶寬受限問題。

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.
