Abstract
Using photographic flash for candid shots often results in an unevenly lit scene, in which objects in the back appear dark. A spatially adaptive photographic flash () is disclosed, in which the intensity of illumination () varies depending on the depth and reflectivity () of features in the scene. Adaption to changes in depth are used in a single-shot method. Adaption to changes in reflectivity are used in a multishot method. The single-shot method requires only a depth image (), whereas the multi-shot method requires at least one color image () in addition to the depth data ().
