Abstract
A motion estimation method for determining a resultant motion vector. The motion estimation method includes: performing a first searching operation starting from an initial motion vector to determine an intermediate motion vector, wherein the first searching operation is performed according to a first searching principle; and performing a second searching operation starting from the intermediate motion vector, to determine the resultant motion vector, wherein the second searching operation is performed according to a second searching principle. The first searching operation is a rough search, while the second searching operation is a fine search.
