一、当灰密度(E.N.D)的客观定标法彩色密度的测量在当密度计的光谱响应和胶片染料的选择吸收之间不匹配时,就会造成测量和使用之间不一致,给胶片的制造和使用带来不便。当灰密度是一种用彩色影象达到选择灰时的染料量来度量胶片密度的单位,是染料量的相对计量法。它是研究多层彩色片的层间效应、光谱感 1. When the objective colorimetric (CBS) method of colorimetric measurement of the end-point density (END) does not match the spectral response of the densitometer and the selective absorption of the film dye, it causes inconsistencies between measurement and use, giving film manufacturing And inconvenience to use. When the gray density is a measure of the density of the film by the amount of dye when the color image is chosen to be gray, the relative amount of dye is measured. It is the study of multi-layer color film interlayer effect, spectral sense
