The principle and algorithm of electronic image stabilization are analyzed. A new algorithm is proposed to realize the electronic image stabilization. The algorithm uses the spatial least-squares error and the spatial correlation of the inter-block motion vector as the matching function, and calculates the motion vector using the four-step search method and compares it with the motion vector obtained from the full search algorithm. Experiments show that this algorithm can achieve the stability of the image sequence well.
