Abstract: An image white balance processing method is provided. The image white balance processing method includes: calculating color coordinate points; when it is determined that the color coordinate points are in a first given region, calculating a plurality of weighted averages according to a plurality of coordinate components and a plurality of weight values of color coordinate points of a white given image region, and when it is determined that the color coordinate points are in a second given region, calculating a plurality of averages according to a plurality of coordinate components of color coordinate points of a green given image region; calculating an estimated coordinate point; and calculating a plurality of white balance gains according to the number of a plurality of white given image regions and green given image regions, the plurality of weighted averages, and the estimated coordinate point to compensate for the plurality of given image regions.
