Abstract
Abstract An image pickup apparatus comprises a movement detector for detecting a movement of an object image frame and outputting movement information, a tracking device for tracking the object image on the basis of the movement information of the object image frame detected by the movement detector, a motion detector for detecting a motion of the object in the object image frame and a controller for changing operating characteristics of the motion detector in correspondence with an operation state of the tracking device.
