1. An apparatus comprising:
an image sensor configured to output a signal for focus detection processing;
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform operations including:
detecting a defocus amount of an image of a target subject to be subjected to the focus detection processing based on the signal for the focus detection processing;
controlling a focusing lens movement based on the defocus amount; and
determining whether the target subject to be subjected to the focus detection processing is a saturated subject,
wherein, in a case where a state where a variation in the detected defocus amount or a variation in a moving amount of an imaging plane is smaller than a predetermined value continuously occurs a predetermined number of times or continues for a predetermined time duration, the target subject to be subjected to the focus detection processing is determined to be a saturated subject in the determination.
