ABSTRACT:
Interlaced video signals are processed by mixing spatially interpolated video signals with temporally interpolated video signals. The respectively interpolated signals are mixed in dependence on a degree of motion at the given location in the video picture, as defined by a motion decision parameter. In order to dependably determine whether motion is to be taken into account in a current frame, motion decisions of previous frames are taken into account. That is, to define the motion decision parameter and to exclude false determinations, the motion decision parameter is computed recursively, by taking into account motion decision parameters of the associated previous fields.
