Patent ID: 8879633

Claim:
A method comprising: determining a plurality of candidate motion vectors for a first pixel block in a current frame of a sequence of frames of image data, the candidate motion vectors including each of the following: (a) a motion vector for a pixel block that adjoins the first pixel block; (b) a motion vector for a pixel block that is a superset of the first pixel block; (c) a motion vector for a second pixel block that is part of a first reference frame of image data that immediately precedes said current frame in said sequence of frames of image data, said second pixel block having a position in the first reference frame that corresponds to a position of the first pixel block in said current frame; and (d) a scaled motion vector for a third pixel block that is part of a second reference frame, the second reference frame preceding said first reference frame in said sequence of frames of image data, said third pixel block having a position in the second reference frame that corresponds to a position of the first pixel block in said current frame; determining a number of said plurality of candidate motion vectors that are the same; and comparing said number to a threshold.
