Patent ID: 8000561

Claim:
An apparatus for processing an image, comprising: an image aligning unit to shift at least one image selected from images to be stitched for maximizing a color similarity between overlapped sections of the images and to operate again in response to a re-alignment signal; a comparison unit to compare a difference between a color similarity of the overlapped sections as a result of a current shifting of the at least one image and a color similarity of the overlapped sections as a result of a previous shifting of the at least one image with a critical value; a correction parameter calculation unit to calculate a correction parameter in consideration of the colors of the overlapped sections as a result of the shifting of the at least one image; and an image correction unit, implemented by at least one processing device, to generate the re-alignment signal after correcting a color of at least a part of the overlapped sections as a result of the shifting of the at least one image in consideration of colors of the overlapped sections using the calculated correction parameter, in response to a result of the comparison.
