Patent ID: 8526502

Claim:
A method for providing line based vertical motion estimation and vertical motion compensation in consecutive frames of a motion picture, wherein the picture is divided in at least one region, the method comprising: a first summing of luminance values for each horizontal line of the at least one region of a previous frame, wherein said first summing of luminance values results in a previous accumulation profile; a second summing of luminance values for each horizontal line of the at least one region of a current frame, wherein said second summing of luminance values results in a current accumulation profile; and deriving a vertical motion vector by use of the previous accumulation profile and of the current accumulation profile, wherein the deriving a vertical motion vector comprises: selecting summed luminance values of a number of horizontal lines of the a least one region of said current frame around a central line of the at least one region of said current frame in the current accumulation profile as a subprofile of the current accumulation profile, and matching the subprofile of the current accumulation profile in the previous accumulation profile.
