1. Image processing method, comprising providing a sequence of at least two image frames calculating a motion vector representing relative movement of at least a part of said image frames, repositioning at least said part in the image frames in accordance with the calculated motion vector, combining the image frames to form a combined image frame, dividing the image frames into blocks, calculating a block motion vector representing relative movement of each block, repositioning each block in accordance with the calculated block motion vector and combining the blocks to form combined blocks in order to obtain the combined image frame.
