Abstract

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).
