Abstract
Method, device and computer program product for stabilizing a video signal. A plurality of frames of the video signal are captured using a camera. A motion sensor associated with the camera is used to generate a plurality of samples representing motion of the camera. The samples are used to determine a displacement of the camera between a first time and a second time, wherein the first time corresponds to an exposure time midpoint of a first frame of the video signal and the second time corresponds to an exposure time midpoint of a second frame of the video signal. The determined displacement is used to compensate for motion in the video signal between the first and second frames caused by the motion of the camera, to thereby stabilize the video signal.
