Abstract
Compensation of ambient illumination. A visible image of an object with ambient illumination is captured. Image brightness of at least a portion of said object of said visible image is sampled. A difference between sampled image brightness of at least said portion of said object and a target brightness profile is determined. The difference is compensated for by projecting additional illumination onto said object.
