Provided are a method and apparatus for correcting a shake of a digital photographing apparatus. The method includes sensing a shake via an inertial sensor comprised in the digital photographing apparatus, and calculating a first shake value; comparing the first shake value with a predetermined threshold value and, when the first shake value is greater than the predetermined threshold value, driving an OIS (optical image stabilizer); detecting an edge component of an image of a target subject, wherein the image is input via an imaging device of the digital photographing apparatus, and calculating a second shake value from a difference value between edge values of sequential frames of the input image; and comparing the second shake value with the first shake value, and according to a result of the comparing, controlling a shake of the target subject to be corrected.
