tristimulus values

基本解釋

The computation of tristimulus values is a basic step for obtaining various colorimetric quantities.
三刺激值計(jì)算是求取各種色度量的基礎(chǔ)。
Since this CIE1931 RGB system results negative tristimulus values in calculation, the CIE1931 XYZ standard colorimetric observer was brought forth.
但是，CIE1931 RGB系統(tǒng)在計(jì)算顔色的三刺激值時(shí)會(huì)出現(xiàn)負(fù)值，由此産生了CIE1931 XYZ標(biāo)準(zhǔn)色度系統(tǒng)。
According to the experimentt, hree color printing ink measurement can demarcate the color gamut range and analyze the factor on its color range under different condition of tristimulus values.
通過實(shí)騐方法，測(cè)量三原色油墨在不同印刷條件下的三刺激值，標(biāo)定其色域範(fàn)圍，分析影響其顯色範(fàn)圍的因素。

three values that together are used to describe a colour and are the amounts of three reference colours that can be mixed to give the same visual sensation as the colour considered ( symbol: X, Y, Z)&rarrsee alsochromaticity coordinates

三刺激值
The device-independent tristimulus values XYZ, which were required in the indirect way of spectral reconstruction, were transformed from the device-dependent RGB signals by using the colorimetric characterization model of the camera.
通過色度特征化模型,將設(shè)備相關(guān)的RGB值轉(zhuǎn)換成設(shè)備無關(guān)的三刺激值XYZ,從而實(shí)現(xiàn)間接途逕的光譜重?fù)k。
