Digital photographing apparatus and control method thereof

Abstract

A digital photographing apparatus that recommends a suitable auto focus (AF) candidate area to a user before photographing, allows a user to select an AF area or automatically selects the AF area, and allows a user to conveniently and accurately capture a desired image, and a method of controlling the digital photographing apparatus are disclosed. A method is provided that includes calculating information about a distance to an object existing in an image stereoscopically input through a first lens and a second lens; matching the information about the distance to red green blue (RGB) information of the image; displaying a plurality of AF candidate areas on the image based on the matched RGB information; and capturing an image centered on an AF candidate area having a first priority when a photographing button is pressed.
