To enable settings of an imaging device to be automatically switched as necessary.

When movement of a camera is detected during live-view display, processing for shortening a shutter second time is performed after a lapse of a predetermined time (e.g., an exposure mode is switched to a sport mode). Thereafter, when the stop of the camera is detected, it returns to an original state after a lapse of a predetermined time. However, when it is determined that panning photographing is being performed, the processing for shortening the shutter second time is not performed.
