Abstract
Embodiments disclose methods and apparatuses for camera motion analysis in a video, wherein one of the methods includes: analyzing, video segments with significant movement characteristics and video segments without any significant movement characteristic; for each segment without any significant movement characteristic, if a first motion type corresponding to a preceding neighboring video segment is different from a second motion type corresponding to a succeeding neighboring video segment, lowering detection criterions of the first type and the second type; judging whether the segment without any significant movement characteristic meets the lowered detection criterions; and merging the segment without any significant movement characteristic with a neighboring video segment according to the result of judgment. With the embodiments of the invention the motion type of a camera in the video can be detected more effectively and accurately, and the photographic intention of a user can be reflected more accurately.
