ABSTRACT:
A tracking image pickup device which makes it possible to perform high-speed and high-accuracy drive and tilting drive without sacrificing the rigidity of the device. An image pickup section has a predetermined optical system and acquires an image pickup signal through the optical system. A tracking target-detecting section detects a tracking target from the image pickup signal acquired by the image pickup section. A drive section has a fine movement part formed by a part of the optical system, and a rough movement part, so as to turn the tracking image pickup device in a panning or tilting direction. A control command value-computing section drivingly controls the drive section such that an amount of deviation between the tracking target and an image pickup direction of the tracking image pickup device is reduced. An image pickup direction-computing section determines the image pickup direction of the tracking image pickup device.
