Abstract: Provided are a digital photographing apparatus capable of accurate and quick auto-focusing, a method of controlling the digital photographing apparatus, and a recording medium storing a program for executing the method. The digital photographing apparatus includes: a lens unit including a focus lens; an imaging device generating data from light incident on the imaging device through the lens unit; a condition determining unit determining a photographing condition from the data generated by the imaging device; and an auto-focusing value detecting unit detecting an auto-focusing value from the data generated by the imaging device and comprising a first gamma correction unit, wherein the first gamma correction unit varies the degree of gamma correction according to the photographing condition determined by the condition determining unit, and the auto-focusing value detecting unit detects an auto-focusing value.

Abstract: Provided are a digital image photographing apparatus which easily captures an image of a composition intended by a user, a method of controlling the apparatus, and a recording medium having a program for executing the method. The apparatus includes: an image capturing device for receiving light to generate data on an image; and an auto-focusing tracking unit for allowing a lens to be auto-focused on a subject selected by a user. The image capturing device generates data on a still image when the subject on which the lens is auto-focused is located in a predetermined region of interest (ROI).
