Abstract
An image pickup apparatus capable of calculating a light amount change characteristic of light from an object according to a state of the object. In the image pickup apparatus, the luminance change-based flicker detection for detecting flicker of a light source by calculating the light amount change characteristic of light from a photographing object based on sequential image data obtained by an image pickup device, and the luminance distribution-based flicker detection for detecting flicker by calculating the light amount change characteristic based on luminance distribution data generated from the image data are selectively performed according to the brightness of the photographing environment.
