A method and apparatus for searching a reference picture 600 comprising a plurality of reference blocks for a block that best matches a current picture block is disclosed. The method comprises: designating, in a current picture 610, a subset of current blocks; applying a first search algorithm to the subset of current blocks and applying a second search algorithm to current blocks outside of the subset. The main difference between the first and second search algorithms is that the search area within a corresponding reference picture is of a variable size in the first algorithm, whereas the second algorithm is a basic four-step motion search. |
