Abstract
A method for selectively adjusting the amount of specular reflections appearing in the final image output by an image capturing device by blending two substantially perfectly overlapping images, one with natural specular reflections and one without specular reflections. In the combined image, the amount of specular reflection is lower than in the image having natural specular reflections, to the extent in many cases that the underlying image content can be seen. In any event, the apparatus provides means for selectively adjusting the intensity of specular reflection, or even eliminating it altogether, in each region of the image containing such reflection.
