In view of the timeliness demands of an Digital Image Stabilization (DIS) system, a fast local motion estimation method is proposed, which combines the advantages of the sub-sampling technology, bit-plane matching (BPM) and the 3 step search (3SS). The algorithm cuts the search and comparison times from 225 to 24 while keeping its accuracy invariable. The pixels of the sub-image participating in the estimation have been increased by a factor of 4 by based on sub-sampling technique but its operation quantity keeps invariant. This improves the capability of anti-interference induced by the movement of sub-image object. The experiments show that the search speed of the algorithm has been obviously improved but its accuracy keeps invariant. The obtained matching position very much approaches that obtained by full search matching algorithm.
