ABSTRACT:
To track a region of interest (“ROI”) such as, for example, in a viewfinder of a camera, both the location and distance of a point in the ROI are estimated for a time in the future, based on actual measurements of locations and distances of the point at the present and in the past. Focus is controlled so as to focus on the point of interest based on the estimate of the future location and distance.
