Abstract
Disclosed is a method for setting an auto white balance area. An image is received from an image sensor. An edge from the image is detected and an edge area having no color information is removed from the image. The image, from which the edge area is removed, is divided into blocks having preset sizes. Remaining areas are set as an auto white balance area except a darkest area and a brightest area by applying a threshold value for brightness to the divided image.
