Abstract
The motion estimation unit () comprises a block-matcher () for calculating a start motion vector () by minimizing a predetermined cost function as a matching criterion for the block () of pixels with a further block of pixels () of a further image (). The motion estimation unit () further comprises an optical flow analyzer () for calculating an update motion vector () based on the start motion vector () and which is designed to find the most appropriate set of optical flow equations corresponding to respective pixels of the block () of pixels. This is achieved by analyzing gradient vectors of optical flow equations for pixels of the block () of pixels. Finally the selectorof the motion estimation unit () selects the motion vector () by comparing the start motion vector () with the update motion vector ().
