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.

Provided is an interchangeable lens digital camera that is capable of correcting a rolling shutter distortion in a live view image without delay in displaying the image. At the start of live view imaging, a lens controller in an interchangeable lens controls a shake detection sensor to detect the direction and amount of a shake, and produces deviation information on the basis of shake detection signals from the shake detection sensor, the deviation information indicating fluctuation in direction and amount of the shake for one frame of the live view image in the form of a parameter.
