A system (26) for stabilizing a video recording of a scene (20, 22, & 24) made with a video camera (34) is provided. The video recording may include video data (36) and audio (38) data. The system (26) may include source frame storage (64) for storing source video data (36) as a plurality of sequential frames. The system (26) may also include a processor (50) for detecting camera movement occurring during recording and for modifying the video data (36) to compensate for the camera movement. Additionally the system (26) may include destination frame storage (70) for storing the modified video data as plurality of sequential frames.

[ What is claimed is:] [1.] A method for stabilizing a video recording of a scene made with a video camera, comprising the steps of:separating video data of the video recording into a plurality of frames;dividing each frame into a plurality of blocks;determining for each frame, a motion vector for each block representing direction and magnitude of motion in the block, said motion vectors being determined from a comparison of each block in a first one of the frames and a second one of the frames;comparing the motion vectors for each block in one of the plurality of frames with the motion vectors for each block in another of the plurality of frames adjacent to the one frame; anddetecting camera movement when the motion vectors for the one frame are different from motion vectors for an adjacent frame; andmodifying the video data to compensate for the camera movement.
