Abstract
A method and apparatus for copying and blending a source region of an image into a target region of an image is presented herein. Specifically, a method is described for generating a difference color map from colors sampled in a source region and colors sampled just outside of a target region. The difference color map is applied to the source region stored. The results are stored in the target region. If no additional input has been received to modify the source region or the target region, then a larger difference color map may be generated and used to copy and blend the source region into the target region. A source region may appear to be better blended into the target region if a larger difference color map is used.
