Abstract: Because of scene illumination or camera calibration，the color appearance of the same object between different viewpoints will be different in multi-view images system.Tradition illumination compensation algorithm for image is unable to solve this problem effectively.In this paper，a novel multi-view images color correction algorithm is proposed based on retinex color constancy theory.Histogram equalization，retinex processing and color restoration are performed for multi-view images，and extract reflectance which describe object intrinsic properties to eliminate un-consistent light source influence.The experimental results show that corrected images not only have high color contract，also have consistent color appearance with others.

Key words: image correction, color constancy, Retinex, histogram equalization, color restoration

摘要： 在多视点图像系统中，由于场景光照或相机标定的原因，通常会导致同一对象在不同视点位置颜色外表的不一致。传统的亮度补偿算法难以有效地解决这个问题。基于Retinex颜色恒常性理论，提出了一种新颖的多视点图像规正算法，通过直方图均衡化、Retinex处理和颜色恢复手段，提取出反映物体本质特征的反射光系数来消除不一致光照的影响，在增强单视点图像对比度的同时，将视点间图像的颜色规正到一致的水平。
