Patent ID: 8849011

Claim:
A method for compensating a boundary of a video image, wherein each scan line in the video image is shifted by a corresponding line shift amount, the method comprising: determining a boundary region for the video image; moving each pixel in a scan line from an original position to a new pixel position within the boundary region, wherein the new pixel position is determined through a boundary compensator of a video processing system according to the width of the boundary region, the original position, and a line shift amount, wherein the scan line is shifted by the line shift amount; and interpolating at least one pixel into the scan line according to the moved pixels for generating a compensated video image, wherein the new pixel position is evaluated as the following: P new =P ori1 +D shift ×P ori1 ÷N Wherein P new represents the new position, P ori1 represents the original position before the scan line is shifted by the line shift amount, D shift represents the line shift amount, and N represents the width of the boundary region.
