PCT No. PCT/SE93/00313 Sec. 371 Date Oct. 13, 1994 Sec. 102(e) Date Oct. 13, 1994 PCT Filed Apr. 8, 1993 PCT Pub. No. WO93/21733 PCT Pub. Date Oct. 28, 1993.A method for estimation of global error motion vectors, which represent unwanted global picture instabilities in a picture sequence in digital video signals. The method uses a motion vector estimator with an adaptively variable measuring time distance, as well as spatial processing and temporal processing, in order to estimate a sequence of global motion vectors, from which a sequence of global error motion vectors is separated in order to allow stabilization of a picture sequence in digital video signals.
