<p>For compensation and/or estimation of motion in a digital video image a search area or window (S) is defined for an actual image segment (BD-B) such that all data that can be accessed via motion vectors from all pixels in the actual image segment (BD-B) is contained in the search area (S). The actual segment (BD-B) includes a number of pixel blocks positioned in a single horizontal row in the image and the search area (S) has a width in the horizontal direction including a higher number of pixel blocks. When progressing over the image the search are (S) is shifted from one segment to the next with a vertical scanning direction (SC). An update area (UP-B) may be attached to the search area (S) to prepare for processing of the next image segment concurrently with processing of the actual segment.</p>
