1. A method for testing a motion vector, which has a provision of at least one item of motion information assigned to an image sequence, the method comprising: storing a first image section of a first image of the image sequence in a first buffer memory; storing a second image section of a second image of the image sequence in a second intermediate memory, whereby a position of the first image section in the first image and a position of the second image section in the second image having a reciprocal offset which is dependent on the at least one item of motion information; determining a first image block in the first image section and a second image block in a second image section using the motion vector; and comparing the contents of the first and of the second image block.
