Abstract
An imaging apparatus includes an image sensor, an acquiring unit, and at least one processor. The image sensor is capable of acquiring, from an imaging surface that captures an object image formed by an optical system, first and second paired signals which are respectively acquired by pupil division in first and second directions different from each other. The acquiring unit acquires first and second defocus amounts from phase differences between the first paired signals and between the second paired signals, respectively. The at least one processor functions as a detecting unit and a deciding unit. The detecting unit detects an imaging object in an imaging frame. The deciding unit decides, based on the detected imaging object, at least one defocus amount to be used in focus control for the optical system from the first and second defocus amounts.
