摘要
An auto focus (AF) adjusting method, an AF adjusting apparatus, and a digital photographing apparatus including the same, the AF adjusting apparatus including: an AF calculator for calculating focus detection evaluation values; a peak detector for detecting a peak position of the focus detection evaluation values; and a speed calculator for calculating a moving speed of a subject by using the peak position. When continuous photographing of still images is performed, the peak detector detects the peak position in an image pickup interval before a light exposure preparation interval for image capturing, and the focus lens driver performs moving body compensation driving for compensating for a focal position by using a moving speed calculated in the light exposure preparation interval before capturing starts.
