Abstract
An electronic device includes a camera device configured to adjust a focus; a distance extraction device; and a processor configured to: obtain a first image using the camera device; set a first region of interest for focus detection in a portion of the first image; obtain first depth information using the distance extraction device, the first depth information including a depth distance corresponding to at least one pixel included in the first image; set a second region of interest in another portion of the first image based on at least two portions which differ in depth distance being included in the first region of interest based on the first depth information; and capture an image based on a focus determined corresponding to the second region of interest.
