Abstract: An image stabilizing apparatus for correcting an image which is shaken due to a movement of a camera. The image stabilizing apparatus includes an image adjusting unit that includes: an image analyzing unit which compares an image frame currently input with a reference image, and if the currently input image frame is shaken, extracts a representative direction and a representative magnitude of the shaking; and an image moving unit which moves the currently input image frame by the representative magnitude in a direction opposite to the representative direction.

Abstract: Provided are an apparatus and method for outputting a stabilized image even when a camera sways. The method includes: applying a first compensated motion to the image to acquire a first stabilized image, wherein an accumulation result of first motions, each of which is estimated between adjacent images from a reference image to an arbitrary image, is inversely transformed into the first compensated motion; and acquiring a second motion estimated between the reference image and the first stabilized image and applying the accumulation result of the first motions and a second compensated motion to the image to acquire a second stabilized image. An accumulation result of the second motion is inversely transformed into the second compensated motion.
