Abstract:
1. A method for determining a motion vector for a current block of a current image in a sequence of video images, each video image being divided into a plurality of blocks, said method comprising: determining, with a calculation unit, a line or column motion vector common to all blocks of a line or column of blocks in a previous image of the sequence of video images based on motion vectors of the blocks in the line or column of blocks, the line or column of blocks including a block located at a position corresponding to a position of the current block in the current image; and assigning, with a selector, the determined line or column motion vector common to all the blocks of the line or column of blocks in the previous image as the motion vector for the current block in the current image, wherein said determining the line or column motion vector only takes motion vectors of the blocks in the line or column of blocks of the previous image into account which exceed a predefined threshold value, and wherein said determining the line or column motion vector further comprises:
