Abstract
Digital video stabilization is selectively turned off in circumstances where it could actually decrease the quality of a captured video. A video camera includes a device for directly detecting physical motion of the camera. Motion data from the motion detector are analyzed to see if video stabilization is appropriate. If the motion data indicate that the video camera is stable, for example, then video stabilization is not applied to the video, thus preventing the possibility of introducing “motion artifacts” into the captured video. In another example, motion as detected by the motion detector can be compared with motion as detected by the video-stabilization engine. If the two motions disagree significantly, then the video-stabilization engine is probably responding more to motion in the captured video rather than to motion of the camera itself, and video stabilization should probably not be applied to the video.
