A digital photographing device in which processing time for correcting optical distortion is shortened. A first distortion correction circuit, which can carry out processing at a low correction accuracy but in a short time, and a second distortion correction circuit, which carries out processing at a high correction accuracy but requires time for processing, are provided at an image processing circuit for processing digital image data. Control is carried out such that the second distortion correction circuit is selected and carries out optical distortion correction at a high accuracy only at a time of actually photographing a still image (i.e., when the still image photographing mode is selected and a release button is depressed fully). In other cases, control is carried out such that the first distortion correction circuit is selected.
