Monitor intensity ranges are much lower than the range of intensities in the real world or even in high quality renderings. Rendering in high dynamic range (HDR) is becoming more common in computer graphics. HDR video cameras are also available. The process of compressing a single frame of HDR data (real or synthetic) into a range displayable by monitors is called tone mapping. Videos (a real or synthetic sequence of images) require this technique as well. Tone mapping video introduces a temporal constraint to maintain consistent intensities between frames. We present a novel method, called adaptive temporal tone mapping, which provides smooth intensity transitions in tone mapped video, while allowing for discontinuous dynamic lighting changes (such as turning on a light or exiting a tunnel).
