Patent ID: RE39276

Claim:
A method of determining motion compensation for an input image from motion vectors between the input image and a plurality of reference images, said method comprising the steps of: (a) calculating a motion vector MV 1 between the input image and one reference image of said plurality of reference images from a motion of at least one block unit at a second set time interval T 2 between the input image and said one reference image, said at least one block unit being a part of said input image and comprising a plurality of pixels; (b) providing a motion vector MV 2 between at least two reference images of the plurality of reference images at a first set time interval T 1 , which is parallel to the motion vector MV 1 at the second set time interval T 2 and different in magnitude from the motion vector MV 1 at the second set time interval T 2 by a value determined by MV 1 ·T 1 /T 2 ; and (c) calculating the motion compensation of the input image from both of (i) the motion vector MV 1 between the input image and said one reference image and (ii) the motion vector MV 2 between the at least two reference images of the plurality of reference images.
