Abstract: 0The color of the color image and the obJect itself tends to deviate greatly when the image is acquired by the smart camera,due to the limitation of imaging conditions.In this paper,a new color correction method was proposed to reduce the deviation and improve the color reducibility.In this method,the most approximate Color Matrix is obtained by least square method in RGB color space,and then optimized in L*ab Color space.The color matrix obtained by this method improves the method of approximating the target value by exhaustive method in RGB space.In order to verify the effectiveness of the new algorithm,the standard D65 light source is used as the lighting source,Color Check24/ColorCheck+Vectorscope is used as the experimental obJect and the measurement correction result was obtained.Comparison experiments show that the color balance effect of the new method is better than that of the traditional color matrix calculation method.

Key words: Color correction, Color deviation, Color equalization, Color matrix, Least square method, OSID
