Abstract

An image to be interpolated is subdivided into a number of image blocks and a motion estimation technique is implemented to provide at least one initial motion vector for each of the image blocks. A modified motion vector is generated for each image block based on the initial motion vectors assigned to the individual image blocks. At least one additional image block is determined through which the motion vector assigned to the given image block passes at least partially, and the modified motion vector is generated as a function of the initial motion vector that is assigned to this at least one additional image block.
