Abstract
A method applies fast and accurate autofocusing (AF) by using a contrast AF method in a digital photographing apparatus. In the digital photographing apparatus, when AF peaks of a subject of a central multi-point and a subject of a nearest multi-point are detected, further scanning is not performed. In addition, scanning is not performed on a region from which it is difficult to detect a peak, so that fast and accurate AF may be performed.
