    We propose an efficient motion estimation algorithm to search an additional area according to the motion of a camcorder, which is obtained from a gyro sensor. When the camcorder moves, the background moves in the opposite direction. The proposed algorithm searches three regions, one around the center, another around the predicted region and another in the background around the region associated with the camcorder motion. Compared to conventional algorithms without the last region, the proposed one reduces the amount of computation to 1/5 while maintaining or enhancing the quality.
