Abstract:
An auto white balance (AWB) method and an image photographing apparatus using the same. The AWB method includes selecting parts of a plurality of windows that form an image, and performing an AWB of the image, based on color difference signals of the selected windows, thereby reducing a time to transmit AWB data to calculate color difference integration, i.e., AWB data to be used to perform the AWB, to reduce the extent of calculation to calculate the color difference integration, and efficiently to perform the AWB of the image.
