Claim Text:
1. A video anti-shaking method, comprising: obtaining a first global relative motion vector and a sequence of second global relative motion vectors, wherein the first global relative motion vector represents a global relative motion vector of a current video frame relative to a video frame which is previous and adjacent to the current video frame, and the sequence of second global relative motion vectors comprises one or more second global relative motion vectors each of which represents a global relative motion vector of a reference video frame relative to a video frame which is previous to and adjacent to the reference video frame; calculating a sequence of third global relative motion vectors based on the first global relative motion vector and the sequence of second global relative motion vectors, wherein the sequence of third global relative motion vectors comprises one or more third global relative motion vectors each of which represents a global relative motion vector of a reference video frame relative to the current video frame; filtering the sequence of third global relative motion vectors to obtain a motion vector for compensating shaking of the current video frame; and cropping an entire pixel image of the current video frame based on the motion vector for compensating shaking of the current video frame and a predetermined size of an effective pixel image to obtain an image after anti-shaking compensation.
