Abstract -Automatic white balance is an important function ofdigital still and video cameras. The goal ofwhite balance is to adjust the color of the pixels under different illumination automatically. In this paper, we proposed a new method of automatic white balance. In our algorithm, we detected the image edges on the value of Cb and C, firstly, and then took the pixels near edges in the both side as references pixels to calculate the correction coefficients for R, G and B respectively. The experimental results show that our algorithm performs well even though the images are dominated by few chromatic regions and short of highlight near-white highlight pixels..
