Abstract:
1. A device comprising: a candidate selector that is capable of accepting a current macroblock, the candidate selector adapted to select a motion vector candidate from a set of motion vector candidates with regard to the current macroblock using an accuracy indicator corresponding to the selected motion vector candidate; a refinement case ascertainer that is capable of accepting the selected motion vector candidate and the accuracy indicator corresponding thereto, the refinement case ascertainer adapted to ascertain a refinement case from among a plurality of refinement cases based on a first threshold and a second threshold and responsive to the accuracy indicator, a refinement case analyzer that is capable of accepting the ascertained refinement case, the refinement case analyzer adapted to analyze a collection of points defined by the ascertained refinement case with regard to the current macroblock to potentially refine the selected motion vector candidate; wherein the refinement case analyzer is adapted
