This paper presents a novel fast block matching algorithm based on high-accuracy Gyro for steadying shaking image. It
acquires motion vector from Gyro firstly. Then determines searching initial position and divides image motion into three
modes of small, medium and large using the motion vector from Gyro. Finally, fast block matching algorithm is
designed by improving four types of templates (square, diamond, hexagon, octagon). Experimental result shows that the
algorithm can speed up 50% over common method (such as NTSS, FSS, DS) and maintain the same accuracy.
