Abstract: A motion estimation method is provided. The method has the following steps of: determining a start searching point according to multiple neighboring macroblocks of a current macroblock, wherein the current macroblock corresponds to a searching window; determining a best candidate pixel according to a first line segment where the start searching point is located, and a second/third line segment above/beneath the first line segment; determining whether the best candidate pixel is located at the first line segment; if so, setting a candidate motion vector corresponding to the best candidate pixel as a first motion vector of the current macroblock; and if not, dynamically adjusting the second line segment or the third line segment in the searching window to update the best candidate pixel, and retrieving the first motion vector of the current macroblock corresponding to the updated best candidate pixel.
