AUTOMATIC TRACKING DEVICE AND AUTOMATIC TRACKING METHOD

摘要

It is constructed so that a subject of a tracked object can be imaged larger even during tracking and a feature of the tracked object such as a person can be specifyed easily while continuing the tracking.;An automatic tracking apparatus controls a direction of an imager 11 and adjusts an imaging region so as to include a tracked object in imaged video by a pan/tilt/zoom controller 13 and a pan/tilt driver 14. Here, a tracking speed is acquired from control information for controlling the imager 11 by a tracking speed decision portion 17. Then, when a tracking speed is a predetermined value or less, a zoom scaling factor is calculated according to the tracking speed by a zoom scaling factor calculator 16 and a zoom scaling factor of the imager 11 is changed by the pan/tilt/zoom controller 13 and a zoom lens driver 15.
