A monitoring camera sets ON or OFF of swing correction in accordance with setting information about whether or not the swing correction of an image (that is, captured image) captured by an image sensor is performed, and corrects swing by cutting out a part of the captured image based on a swing detected value of a vibration sensor in a case where the swing correction is set ON. The monitoring camera outputs the captured image while maintaining a state thereof in a case where the swing correction is set OFF.
