A flash band determination device that is capable of always detecting a flash band with high accuracy. It is determined whether or not there is a flash band caused by an external flash of light, which is an area having a luminance level higher than a threshold level, in a plurality of images which are continuously obtained. The threshold level is changed with respect to an image picked up with an exposure condition which is different from an exposure condition used in picking up a preceding image.
