IMAGE STABILIZATION METHOD AND DEVICE FOR PERFORMING THE METHOD

摘要

An image stabilization method and an image stabilization apparatus for performing the method are provided to estimate the motion of a target frame at a smaller cost by calculating the sum of absolute differences between the target frame and a predetermined templet at some positions. The first area is set up. At the locations of pixels of the first area, the sums of absolute differences between a target frame and a predetermined templet are calculated. The minimum value is extracted from the calculated sums. If the location corresponding to the minimum value is at the center of the first area, the displacement of the target frame is precisely estimated within each pixel by using the secondary curve. But, if the location does not exist at the center of the first area, the second area adjacent to the first area is set up.
