Method And Apparatus For Line Based Vertical Motion Estimation And Compensation
First Claim
1. 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 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 of for each 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.

Abstract
The present invention is related to 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, and wherein: in a first summation luminance values for each line of the at least one region of a previous frame are summed, wherein the first summation of luminance values results in a previous accumulation profile; in a second summation of luminance values of for each line of the at least one region of a current frame are summed, wherein said second summation of luminance values results in a current accumulation profile; and wherein a vertical motion vector is derived by use of the previous accumulation profile and of the current accumulation profile.
