Claim One:
1. An apparatus for stabilizing an image based on a correction of a blur of the image, the apparatus comprising: an image receiving unit configured to receive the image; a block dividing unit configured to divide a frame of the image into blocks; an image analyzing unit configured to analyze characteristics of each block to calculate a weight of each block; a significant block extracting unit configured to extract, from the blocks, a block having a weight equal to or larger than a threshold value, determine the extracted block to be a significant block; a feature point extracting unit configured to extract 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 extracted pixels and neighboring pixels of the extracted pixels; a local motion vector calculating unit configured to calculate at least one local motion vector of at least one block 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 configured to calculate a global motion vector based on the calculated at least one local motion vector of the at least one block; and an image correcting unit configured to correct output data of the frame based on the global motion vector.
