关于影像密度测量时光谱条件的探讨

本文概括阐明了由ISO规定,通常用在不同影像技术工作中的主要几种光学密度测量的光谱条件。如:视觉密度、1类型和2类型印片密度、A状态和M状态密度。同时也介绍了光谱乘积的简明定义和教学表达式以及相关数据,且附有有关问题的简单讨论。

On the spectral conditions for image density measurement

This paper presents a brief summary of spectral conditions defined by ISO for the measurement of main types of optical density usually used in routine work of different branches of image technology, e. g. visual density, type 1 and 2 printing density, status A and M density. A concise definition and mathematical presentation of spectral product for defining these spectral conditions and relevant data are thereby introduced. A brief discussion on related problems is also attached.
