Patent ID: RE39277

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 MV1 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 MV2 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 MV1 at the second set time interval T 2 and different in magnitude from the motion vector MV1 at the second set time interval T 2 by a value determined by MV1·T 1 /T 2 ; and (c) calculating the motion compensation of the input image from both of (i) the motion vector MV1 between the input image and said one reference image and (ii) the motion vector MV2 between the at least two reference images of the plurality of reference images.
