Abstract:
1. A method for determining motion vectors that are coordinated with individual image regions of an image, comprising: dividing the image into a number of first main blocks using a first block raster and performing a first estimation process to provide a motion vector for each of the first main blocks; dividing the image into a number of second main blocks using at least one second block raster, a position of the at least one second block raster being shifted relative to a position of the first block raster, and performing a second estimation process to provide a motion vector for each of the second main blocks; forming a number of subblocks, each of the subblocks being formed by an intersection, region between one of the first main blocks and at least one of the second main blocks; and generating a motion vector for each subblock as a function of the estimated motion vectors of the first and second main blocks whose intersection forms that subblock, each of the generated motion vectors for the subblocks being coordinated with the particular subblock; where the dividing the image into the number of first main blocks, the dividing the image into the number of second main blocks, the forming a number of subblocks, and the generating the motion vector are performed by a video image processing device.
