<p>There is provided a method of Motion Estimation in digital video, comprising carrying out an initial search to determine an initial search best candidate motion vector for a source macroblock, carrying out a main search to determine a main search best candidate motion vector for a source macroblock, carrying out a prediction search, centred on the best candidate from the initial search, to determine a prediction search best candidate motion vector for a source macroblock, carrying out a first extended search, centred on the best result from the initial, main and prediction searches, to determine a first extended search best candidate motion vector for a source macroblock, carrying out a second extended search, centred on the best result from the initial, main, prediction and first extended searches, to determine a second extended search best candidate motion vector for a source macroblock, and providing the second extended search best candidate motion vector to a subsequent video encoding process. There is also provided apparatus adapted to carry out the Motion Estimation in digital video method.</p> |
