ABSTRACT:
A method of automatic white balance for an image capture system is disclosed. The automatic white balance mechanism ascertains the illuminant source of an image by analyzing the number of white pixels within a predefined white area in a color space diagram. The automatic white balance mechanism also determines gain adjustments based on the evaluating the average RGB values to achieve white balance.
