Abstract
Provided is a method of controlling a digital camera to enlarge part of an object included in a captured image and display the enlarged part of the captured image on a screen so that the user determines sharpness of the image, which includes determining whether a human face is included in the captured image, selecting the human face in the captured image as a region to be enlarged, dividing the captured image into at least two regions and selecting one of the regions having the largest amount of edge information as a region to be enlarged, enlarging the region selected in the selection step or the dividing and selection steps, and displaying the image enlarged in the enlargement step on a screen.
