Abstract: A method of controlling a photographing apparatus is provided that includes: setting a first exposure time according to a user's input; determining a number of times photographing is performed according to an illuminance and the first exposure time; continuously capturing a plurality of still images the number of times photographing is performed; and generating a resultant image corresponding to the first exposure time by combining the captured plurality of still images.

Abstract: Provided is a focusing method for a digital photographing apparatus by which an image is displayed while a focal lens is moved in response to a manual operation signal generated by a user. The method includes: obtaining a focus value at a current position of the focal lens, wherein the focus value is proportionate to an amount of high-frequency components contained in an image displayed currently; determining a focusing state at the current position of the focal lens based on the focus value of the current position; and changing a sharpness of the currently displayed image such that the result of the determination of the focusing state can be expressed in the currently displayed image. A digital photographing apparatus using the method is also provided.
