The calculation of theoretical "screen effect ''" from the viewpoint of mutual matching of spectral tristimulus values of a CIE standard colorimetric observer with color negative films and color printing papers is described in this article. 本文从彩色负片、彩色相纸与CIE标准色度观察者光谱三刺激值相匹配的角度出发,对理论银幕效果进行了推导。
The idea condition of a hybrid system consists of color input and out devices is that the output devices should be able to make direct use of the data obtained from input, i.e., the input devices should be an standard observer. 在一个由一些颜色输入输出设备组成的混合系统中,理想情况是输出设备能直接利用输入设备获得的颜色数据,即输入设备是一个标准色度观察者。
We have found that spectral response curve of camera is similar with CIE standard colorimetric observer matching functions. 实验发现该数码相机相对光谱响应曲线与CIE1931标准观察者颜色匹配函数相似。
An observer of standard state space systems is designed by using well-known techniques, so the input decoupled observer of the singular linear systems is obtained. 用大家熟知的方法设计正常状态空间系统的观测器,从而得到广义系统的输入解耦观测器。
Since this CIE1931 RGB system results negative tristimulus values in calculation, the CIE1931 XYZ standard colorimetric observer was brought forth. 但是,CIE1931RGB系统在计算颜色的三刺激值时会出现负值,由此产生了CIE1931XYZ标准色度系统。
First, the state space system is converted to the first standard type, and he gives the order of reduced-order observer in accordance with the rank of output matrix of system. 首先把状态空间变换成能观测第I标准型,根据系统输出矩阵的秩决定降维观测器的维数。
After obtained the standard response vector library, similarity measure was employed to observer the relationship between any observation vector and each vector in response vector library. 在己获得标准响应向量库的情况下,利用相似性测度研究了实测任意时刻下的观测点的响应与响应向量库的每个向量的关系。
