High Dynamic Range Imaging


Overview

When shooting digital images of many environments it is impossible to fully capture the real world dynamic range of intensities. Typical scene intensities can range over 5 orders of magnitude while the best digital sensors can only capture 3. There has been a great deal of recent effort in combining multiple exposures of a still scene to create a high dynamic range image of the scene. However until now no one has done this for moving scenes or for video. Through a clever combination of camera firmware and post-processing algorithms we have built a system that captures high-dynamic range video and displays it on a lower dynamic range monitor. For further information check out the paper and accompanying video.
