An image stabilizer and a system having the same, and a method thereof are provided to reduce sudden shift effect which can be generated when movement of a video signal is compensated, thereby improving quality of the video signal. An image stabilizer and a system having the same comprise the following parts: a movement estimating unit(51) for detecting movement vectors of each window from multiple projected windows; a selecting unit(52) for selecting optimal movement vector among the multiple movement vectors; a movement compensating vector computing unit(53) for computing a compensation vector by using the optimal movement vector supplied from the selecting unit; and an image compensating unit(54) for performing image compensation of the image by using the compensation vector. |
