Patent ID: 7263660

Claim:
A method, comprising: identifying a key frame in a video shot, the key frame having a high visual content complexity with a left and a right side; wherein identifying the key frame further comprises: comparing frames within the video shot to obtain candidate frames; obtaining a gravity point by calculating an average point from the candidate frames; sorting the candidate frames according to a distance from the gravity point; and selecting K frames with a shortest distance to the gravity point; measuring a certain length of frames to the left and the right of the key frame for visual content variety; assembling a video skim having L frames to the left of the key frame and R frames to the right of the key frame, wherein the number of frames selected for L and R, respectively, is dependent upon the measured visual content variety to the left and right of the key frame; and selecting a maximum number of frames comprising the video skim, wherein L+R equal the maximum number of frames; wherein L and R each represent a finite integer greater than or equal to zero.
