1. A digital image stabilization method for correcting camera shake of an image capture apparatus, the method comprising: extracting characterizing points from a current frame; matching the characterizing points of the current frame with characterizing points of a previous frame; detecting an outlier from the matched characterizing points and removing the outlier; calculating homography using the characterizing points after the outlier has been removed; and correcting the current frame using the homography, wherein the correcting of the current frame includes, accumulating the homography and previously calculated homography, determining whether each value of parameters constituting the accumulated homography is within a specific range, if each value is within the specific range, correcting the current frame by inversely transforming the current frame using the accumulated homography.
