| 摘要 |
The invention refers to an apparatus and a method for determining a motion vector for a current search block, comprising the steps: detecting the correlation between motion vectors determined for previous search blocks; and depending on the detected correlation, either using a first, or a second search region for determining the motion vector for the current search block. The first search region might be located around the center of the current search block, and the second search region might be located around the tip of a motion vector predicted for the current search block on the basis of motion vectors determined for previous search blocks.
