为了解决环境光和显示器色温对LCD显示器图像颜色再现有较大影响的问题, 提出一种基于LCD显示器光谱特性的图像颜色一致性方法。通过测量在不同环境光和色温下99个行业认可颜色的光谱, 总结出不同环境光和色温对LCD显示器图像颜色再现的光谱规律。利用不同环境光下的光谱叠加性及不同色温下的光谱对应规律, 实现了不同环境光和色温下的LCD显示器图像颜色一致性, 一致性后的图像平均主观评价Z得分为0.50。研究结果表明, 该方法能够很好地解决不同环境光和色温下的LCD显示器图像颜色的一致性问题。

In order to solve the problem that the ambient light and color temperature have a great influence on the image color reproduction of LCD monitor, an image color consistency method based on the spectral characteristics of LCD monitor was proposed. The spectra were of 99 industry-recognized color measured at different ambient light and color temperature, and the spectral color reproduction law of LCD monitor image under different ambient light and color temperature was summarized. Using the spectra superposition under different ambient light and the corresponding law of different color temperature, LCD monitor image color consistency can be achieved under different ambient light and color temperature. The average subjective evaluation Z score of image is 0.50. The results indicate that this method can well solve the LCD monitor image color consistency under different ambient light and color temperature.
