Abstract
An image capturing apparatus, comprises an image sensor having focus detection pixels configured to detect a phase difference of the subject image, a calculation unit configured to calculate a defocus amount of the subject image based on signals of the focus detection pixels, a focus control unit configured to adjust focus of the imaging optical system based on the defocus amount that was calculated, and a determination unit configured to determine whether or not the imaging optical system is in an in-focus state by comparing the defocus amount to a predetermined threshold value, wherein the determination unit sets a larger value for the predetermined threshold value in a case where the imaging optical system focuses on a moving subject than in a case where the imaging optical system focuses on a still subject.
