ABSTRACT:
An incorrect operation is prevented from occurring in a tracking system for keeping track of a photographic object and taking a picture of the photographic object. When a body which is most likely to be recognized incorrectly as a photographic object exists, pan/tilt driving is carried out on a lens block employed in the tracking system so that an optical axis of the lens block is brought into the range of an angle set as an allowed-drive range. By doing so, the lens block will never take a picture of the body. As a result, an incorrect operation can be prevented from occurring due to incorrect recognition of the body as a photographic object.
