An image capture apparatus that carries out exposure control by driving an aperture includes: an image sensor, including multiple pixels, that accumulates and transfers charges per predetermined pixel group; a determination unit that determines an image region in the image sensor that serves as a region from which to output image data for recording or image data for display; and a control unit that drives the aperture within a period in which charge accumulation for the image data for recording or the image data for display is not being carried out for the pixels included in the image region determined by the determination unit.
