摘要：
A method and device is provided for adjusting the white balance of a digital image by adjusting the values assigned to the red, green, and blue subpixels of a pixel in the image. The adjustment to the subpixels is determined by identifying pixels in the image that have an RGB product greater than a threshold value, wherein the threshold value is based at least in part on an average of the RGB products of each pixel in the image and a variance between the RGB products of the pixels and the average of the RGB products.
