  • Patent number: 6005609
    Abstract: A method and an apparatus for tracking a target wherein a shape of a target is extracted from a former image which includes an initial image of the target for tracking, and then an area including the shape of the target is extracted as a correlation area. Based on the correlation area, a checking area is extracted from a current image to check for a correlation. By utilizing a correlation function, the correlation between the former image and the current image is calculated. A location change of the target is calculated to estimate a movement of the target, on the basis of the calculated correlation. Compensating the estimated movement during operation of a camera, the camera is controlled so that a gazing point of the camera can track the target.
