An automatic tracking apparatus controls a direction of an imager and adjusts an imaging region so as to include a tracked object in imaged video by a pan/tilt/zoom controller and a pan/tilt driver. Here, a tracking speed is acquired from control information for controlling the imager by a tracking speed decision portion. 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 and a zoom scaling factor of the imager is changed by the pan/tilt/zoom controller and a zoom lens driver. |
