1. A photographing apparatus comprising: an image sensor configured to continuously receive a plurality of images by using a rolling shutter method; a motion estimator configured to compare at least one pixel line in each of the plurality of images, corresponding to one another in the plurality of images, to determine displacements of the at least one pixel line in the plurality of images, and estimate a uniformly accelerated motion of the photographing apparatus based on the determined displacements of the at least one pixel line in the plurality of images; and an image processor configured to generate an image by compensating for the uniformly accelerated motion of the photographing apparatus estimated by the motion estimator.
