Picture motion measurement

摘要

Television pictures are dividied up into a number of regions and corresponding regions for two pictures are correlated to produce motion vectors at an output connection (2) of a motion vector generator (1) which also at an output connection (4) produces signals signifying relative magnitude and/or width of the vectors which control the weighting operation of a weighting circuit (3). The weighted vectors are applied to a two-dimensional summing arrangement (5) where corresponding vectors from the various regions are summed in individual stores. A largest vector selector (6) selects the most dominant of the motion vectors depending upon the quantities stored in the summing selector (6).
