PURPOSE: A device for high speed motion estimation and a method thereof are provided to reduce the calculation of motion estimation by finding minimum SAD or SSD through block matching and estimating a motion vector. CONSTITUTION: An nth momentum calculating unit(230) obtains nth momentum for a specific block of a current image by using an nth integral image. The nth momentum calculating unit obtains the nth momentum for a specific block of a reference image by using a reference nth integral image. A motion vector estimating unit(240) obtains a block matching error by using a difference between two of the momentum. The motion vector estimating unit estimates a coordinate difference of blocks as a motion vector.
