摘要： In a method and device for determining motion vectors that are each coordinated with individual regions of an image, the image is divided into a number of first main blocks, making use of a first block raster, and a first estimation process is performed to provide each first block with a motion vector. The image is also divided into a number of second main blocks, making use of a second block raster, whose position is displaced relative to or offset from the first block raster, for example in the horizontal and vertical directions, and a second estimation process is performed to provide each second main block with a motion vector. A number of subblocks are formed, each subblock being formed by an overlap region between one of the main blocks of the first raster and certain ones of the second main blocks of the second raster. A motion vector for each subblock is generated, this motion vector depending on the motion vectors of the main blocks and being coordinated with the particular subblock.

摘要： The invention realtes to a film scanner comprising a frame sensor (4) for picking up film frames, and a scanning device (13) at least for scanning a sprocket hole associated with a film frame. To determine the position of a sprocket hole, the film scanner comprises an evaluation device (25) which is provided to determine, in given areas, edge positions in a measuring frame supplied by the scanning device (13), form lines from the determined edge positions and determine the deviation of the center of the sprocket hole from a reference center.
