Abstract
An apparatus for stabilizing an image includes: an image analyzing unit analyzing characteristics of each block to calculate a weight of each block; a significant block extracting unit extracting, from the blocks, a block having a weight larger than a threshold value, as a significant block; a feature point extracting unit extracting a feature point from the significant block by extracting pixels of the significant block and comparing at least one of color and brightness between the pixels and neighboring pixels of the pixels; a local motion vector calculating unit calculating local motion vectors of blocks corresponding to the feature point by referring a previous frame of the frame and estimating a motion of the at least one block; a global motion vector calculating unit calculating a global motion vector based on the calculated at least one local motion vector.
