摘要
本文从光源作用于测试图极端阶调区域后对中性灰还原影响的角度测量了平板扫描仪的散射光效应,为此设计了置于黑色和白色背景的等距离分布灰色块测试图。实验结果表明,三种被测试的不同类型的平板扫描仪确实存在散射光效应。
In this paper, stray light effects of flatbed scanners were measured due to the scanner illuminate applied to two end tone areas in test targets by which neutral gray rendition was effected. Two test targets were designed including equidistant gray patches placed in black or white background. Experiment results show that, stray light effects really exist in the three tested flatbed scanners with different color rendition levels.
