CORRECTING AN ARTIFACT IN AN IMAGE

A method of correcting an artifact in a captured image includes generating a binary map that corresponds to the artifact in the captured image. The method also includes generating a luminance mask from the binary map, the luminance mask applying a level of correction near an edge of the artifact tha...

More Information
Summary:A method of correcting an artifact in a captured image includes generating a binary map that corresponds to the artifact in the captured image. The method also includes generating a luminance mask from the binary map, the luminance mask applying a level of correction near an edge of the artifact that is different from a level of correction applied at the center of the artifact and generating, a chrominance mask to correct a color of the artifact. The method further includes performing corrections to pixels according to the luminance and the chrominance masks.
