1. An apparatus for extracting a camera motion, comprising: a camera rotation information extraction means for acquiring a tilt and a yaw of a camera by extracting a horizontal line of a sea from an original image, and acquiring a pan of the camera using the acquired yaw and long-distance background features of at least two first natural feature point tracking data existing in the original image; and a camera movement calculation means for calculating the camera movement from rotation angles obtained from the tilt, yaw, and pan of the camera and at least two second natural feature point tracking data existing on a sea plane of the original image.
