Abstract
A method for reducing specular reflection in an image. The method includes capturing a first exposure of a scan surface using a first of a plurality of light sources, capturing a second exposure of a scan surface using a second of a plurality of light sources, determining which pixels captured by the light sources are speckles, and replacing a value of at least one speckle in the image with a different pixel value.
