Abstract
Provided is an improved zoom-tracking method. A point or two points between a Wide point and a Tele point are chosen, histogram information is stored, and a distance to a subject is estimated based on the stored histogram information. A locus curve is selected based on the estimated distance to the subject, and zoom-tracking is performed along the locus curve after a zoom lens reaches a specific point.
