Abstract
A motion estimation method for enhancing a video compression speed, and a video encoder using the same are provided. The motion estimation method includes determining a global motion type of a previous frame from motion vectors of the previous frame, setting a search area for a specified motion block included in a current frame based on the global motion type, and searching for a motion vector within the set search area.
