Abstract
An image pickup apparatus that can decrease the probability of an image in which a main subject is not in focus being captured is provided. An image pickup apparatus 1A includes two image pickup devices 5 and 7 that capture an image relating to a subject image made incident through an image capturing lens, a main subject detecting unit 122 that detects a main subject in the captured image, a phase difference AF control unit 121 that performs focus control on the basis of a phase difference detection signal acquired from a ranging area set in an imaging area, a determination unit 123 that determines whether the main subject is present in the ranging area, and a warning control unit 126 that, if the determination unit 123 determines that the main subject is not present in the ranging area, performs predetermined control for preventing a state in which the main subject is not in focus.
