構成したことを特徴とする画像追尾装置。A television camera that images the target, a target position detector that extracts the target part from the video signal obtained from the camera and detects the position of the target in the screen, and a screen white reference generated from the target position detector. In an image tracking device equipped with means for directing the television camera to the target by a signal related to the deviation of the target position with respect to the position, an aperture mechanism for adjusting the amount of incident light is provided in front of the camera, and the aperture mechanism is used to control the screen when searching for the target. An image tracking device characterized in that it is controlled at the overall average video level, and when tracking a target, it is controlled at the average video level in the vicinity of the target so that the contrast between the target and the background is increased.
