To increase the accuracy of adjusting the main light emission. An amount of main light emission is adjusted on the basis of an estimated pre-light-emitted subject distance or information corresponding to the estimated pre-light-emitted subject distance and an estimated lens-focused subject distance. The estimated pre-light-emitted subject distance and the information corresponding to the estimated pre-light-emitted subject distance are obtained by pre-light-emission processing. The estimated lens-focused subject distance is obtained from focus information through a lens. In a case of bounce light emission, in a case where the estimated pre-light-emitted subject distance is smaller than the estimated lens-focused subject distance, a distance made closer to the estimated lens-focused subject distance from the estimated pre-light-emitted subject distance by a predetermined amount is set as an estimated subject distance for adjusting the main light emission.
