摘要： A method and apparatus is provided for generating a middle level motion vector in hierarchical motion estimation. TA second-resolution-frame motion vector is generated in a second resolution frame having a second resolution from a first-resolution-frame motion vector in a first resolution frame having a first resolution, the second resolution being higher than the first resolution. A local-search reference point is determined in the second-resolution frame based on the first-resolution-frame motion vector, and the second-resolution-frame motion vector is generated by performing a local search process on the second resolution frame based on the determined local-search reference point. The local search process is performed based on matching reference values for lower estimation blocks, each of the lower estimation blocks comprise pixel values of some portions of a current estimation block and a past estimation block. The current estimation block is an estimation block of a current frame and the past estimation block is an estimation block of a corresponding past frame. Accordingly, an amount of operations for the matching reference values can be reduced.
