Abstract
Provided are a digital photographing apparatus and method of performing different degrees of image processing on one or more faces in an image according to the distances of faces from the digital photographing apparatus or whether auto-focusing has been performed on the faces. Also provided are a digital photographing apparatus and method of performing different degrees of image processing which assist in preventing faces at farther distances from appearing more processed, for example, more blurred, than faces at closer distances and which assist in preventing faces that have not been auto-focused from appearing more processed, for example, more blurred, than faces that have been auto-focused.
