Single-Exposure HDR Technique Based on Tunable Balance Between Local and Global Adaptation

This brief describes a high-dynamic-range technique that compresses wide ranges of illuminations into the available signal range with a single exposure. An online analysis of the image histogram provides the sensor with the necessary feedback to dynamically accommodate changing illumination conditio...
