【摘要】：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。
[Abstract]:In order to solve the problem that ambient light and display color temperature have great influence on image color reproduction of LCD display, a method of image color consistency based on spectral characteristics of LCD display is proposed. By measuring the spectrum of approved colors in 99 industries under different ambient light and color temperature, the spectral rules of color reproduction of LCD display images by different ambient light and color temperature are summarized. The color consistency of LCD display image under different ambient light and color temperature is realized by using the spectral superposition under different ambient light and the corresponding law of spectrum under different color temperature. The average subjective evaluation Z score of the consistent image is 0.50. The results show that this method can solve the problem of color consistency of LCD display images under different ambient light and color temperature.
