Abstract
An image pickup apparatus which is capable of detecting a flash band with high accuracy even when no flash light is falling on a part of an image. The image pickup apparatus detects a band-shaped luminance step appearing in a plurality of frame images, which are obtained through image pickup by an image pickup unit, in a video comprised of the plurality of frame images. A detection area, which is for use in detecting the luminance step, is set in a part of the frame image according to a subject included in the frame image. Luminance data is obtained on a line-by-line basis in the detection area, and based on a difference in luminance data between corresponding lines in the frame images, the luminance step is detected.
