1. A method of controlling a digital photographing apparatus, the method comprising:
- comparing pixel values of a previous preview image data with pixel values of a current preview image data; and
controlling the operation of a hand shake correcting unit based on the comparison;
wherein controlling the operation of a hand shake correcting unit comprises;
turning off the hand shake correcting unit during photographing of an image if a result of the comparison meets a first criteria; and
turning on the hand shake correcting unit during photographing of an image if the result of the comparison meets a second criteria;
the hand shake correcting unit moving a hardware unit of the digital photographing apparatus when it is turned on, and not moving the hardware unit when it is turned off;
wherein the hardware unit comprises at least one of a lens and an image pickup device of the digital photographing apparatus.

Abstract
Provided are a digital photographing apparatuses and methods of controlling the same. The method includes: inputting previous preview image data; inputting current preview image data; comparing and determining a pixel value of the previous preview image data and a pixel value of the current preview image data; and controlling the operation of a hand shake correcting unit according to the comparison and determination result. Accordingly, the hand shake correcting unit is selectively turned off by easily detecting a case where hand shake correction is not necessary, such as a case where a tripod is used, thereby reducing power consumption.
