An interpolation method for decimal motion estimation and a method and apparatus for calculating cost functions derived from the interpolation method are provided. The interpolation method comprises the following steps. First, divide the data range needed by an interpolation filtering process into a loaded range and a speculation range. Load the data in the loaded range and then generate the data in the speculation range based on the data in the loaded range. Finally, use the data range as input data to perform the interpolation filtering process.
