Abstract
A method and apparatus for auto white balance in a portable terminal is provided. The method includes analyzing a captured image with histograms of red, green, and blue channels and a histogram of a gray channel; determining whether the histogram of the RGB channels and the histogram of the gray channel overlap over a predetermined percentage; measuring each color distribution average value of the RGB channels when the histogram of the RGB channels and the histogram of the gray channel overlap over a predetermined percentage; and performing color temperature correction using the color distribution average value measured in each of the RGB channels.
