An imaging device (pan/tilt camera) includes an imaging unit including an imaging lens and an imaging element, a pan/tilt mechanism that rotates the imaging unit in the horizontal direction and the vertical direction with respect to a camera body, an object detection unit that detects an object, which is a tracking target, from a moving image captured by the imaging unit, a pan/tilt control unit that controls the pan/tilt mechanism such that the object detected by the object detection unit is tracked, a motion sensor that detects a physical amount related to the movement of the camera body, and an operation control unit that stops the pan/tilt mechanism in a case in which the physical amount detected by the motion sensor is equal to or greater than a first threshold value.
