A portable real-time high-dynamic range video system

Using a single sensor to capture videos of scenes containing very high and very low luminance contents at the same time is still a challenge. An alternative solution is to use multiple sensors and specially designed optics. Such approach also faces some significant technical challenges including the manufacture of precision optics, accurate alignment of different sensors, recovering high dynamic range video frames and rendering them for display in real-time. In this work, we present a new real-time high dynamic range video system which is able to produce high quality live video up to 30 frames per second. The innovative features of the system include novel optics, new high dynamic range radiance map recovery methods and GPU based real-time HDR video processing and display. A video recorded live by the new system can be found in this vimeo link: http://vimeo.com/97595588. We will bring the system to the conference and perform live demo.
