lizhipeng White balancing algorithm only works when there is a little of "white" in the frame, it fails when the image is overexposed. I believe there are some parameters that you can adjust that would enable white balancing only when the conditions are good.
If your image does include overexposed areas (i.e. bright background) the balancing will not work. The good thing is that normally you do not need white balancing to work all the time, it is needed only when the lighting is changed (i.e. from daylight to artificial), so you may disable white balancing fro most of the times and balance it only when needed. In some cases you may even have several presets and switch between them.
