Abstract
Techniques for reducing coloration artifacts visible in digital images acquired under flash lighting conditions are provided. The coloration artifact problem is addressed by capturing two images of the scene, a first image illuminated by a limited spectral bandwidth flash light source, and a second image illuminated by broad spectral bandwidth flash light source. Pixels of the second image are replaced with selected counterpart pixels from the first image that do not contain the coloration artifact.
