温度对精确测量色度及色差的影响分析与研究

在研究影响色度及色差的因素时,人们普遍是从光学、物理学、化学、生理学及心理学角度出发,期望能够尽量消除这些因素的影响,以使测量结果与人眼视觉匹配,并从理论上解释颜色空间的不均匀性.主要从热学角度分析和研究温度对于颜色色度及色差的影响.通过实验发现,在可见光谱范围内,长波,尤其是红色对于温度的变化比较敏感,对色度及色差的影响较大,而中性色(灰色、白色和黑色)受温度变化的影响较小.

Study and analysis of the Influence of Temperature on Chromaticity and Color Difference in Accurate Color Measurement

When we discuss the meaning of chromaticity and color differences, we always want to avoid or diminish the influence from photology, physics, chemistry, physiology and psychology. We want to match the measurements with human color vision and to explain the unhomogeneity of the CIELAB color space or other color spaces in theory. This paper discussed that influence of temperature on the chromaticity and color difference from thermology. We found that the longer wavelength, especially the red color, is more sensitive to the temperature variation and may cause greater influence on chromaticity and color differences. But the achromatism, such as gray, white, black, is less sensitive to temperature variation.
