A system for generating motion vectors from image data calculates correlation surface values representing image correlation between temporally adjacent images. The system provides a stream of correlation surface values comprising interleaved subsets of correlation surface values from differing correlation surfaces, each subset being a portion of a correlation surface. The system also provides a correlation surface analyzer for receiving the stream of correlation surface values and determining partial result values for motion vectors, a buffer memory for storing the partial result values, and an apparatus for reading out final result values of motion vectors for a given correlation surface. |
