摘　　要：提出了一种有效的颜色还原方法,特点是可以还原数码相机在彩色光源下捕获图像的真实颜色。分析了颜色还原的原理及实现过程,用计算机语言编制了该专业软件,并对之进行了实验研究。对比研究了三种彩色光源下,物体颜色被还原的外貌效果,并给出了量化的颜色对比数据。研究表明,用该方法处理后得到的物体颜色值与外界的光源无关且能真实反映物体的颜色外貌,其还原过程与人眼的颜色适应过程相似。A method of color restorations, obtaining the true color values of object images recorded by digital cameras under color light sources, is presented. Mechanisms and implements of color corrections are analyzed, special software for analyzing data is developed based on the above theories and several relative experiments are also conducted. Color appearances of three object images captured under different illuminants are restored and their resuiting color data are also analyzed. This study indicates that the color appearance of an object can be obtained correctly using the proposed method and its seen effect of color restored is similar with that of color constancy of visual systems.
