白平衡卡70%反射率简介

　　分辨率测试卡YE0115测试卡专门为白平衡检测设计。

　　白色区域的密度为0.15(基于BaO4S=0)。

　　白平衡测试卡对应反射率为70%。

　　白平衡测试卡采用是在380~700nm可见光谱下的高均匀型材料(见插图中灰色曲线)。分辨率测试卡在下图缓慢下降趋势的420区域内出现一个急剧下降波形。在这个区域的蓝色和红色的灵敏度较低，光照的反射并没有显著改变。

　　White balance card 70% reflectivity profile

　　Resolution test card The YE0115 test card is specifically designed for white balance detection.

　　The density of the white area is 0.15 (based on BaO4S = 0).

　　White balance test card corresponding reflectivity of 70%.

　　The white balance test card uses a high homogeneous material in the visible spectrum of 380 to 700 nm (see the gray curve in the illustration).　Resolution test card A sharp drop in the 420 area appears in the slow down trend of the figure below. The sensitivity of the blue and red in this area is low and the reflection of the light does not change significantly.
