An imaging apparatus includes an imaging unit which images a subject, a detection unit which detects a state of the subject, and a control unit which, in a predetermined mode for acquiring an image by intermittently imaging a subject using the imaging unit, controls the intermittent imaging operation of the imaging unit for acquiring the image based on a detection result of the detection unit, in which the control unit determines whether a rate of a region in a frame related to the imaging unit is less than or equal to a predetermined rate, the region having a difference between a plurality of successive detection results obtained by the detection unit being larger than a predetermined value, and controls the intermittent imaging operation of the imaging unit in the predetermined mode according to a result of the determination.
