Abstract
We present a new approach to display High Dynamic
Range (HDR) video using gradient based high dynamic
range compression. To obtain HDR video, we utilize the
split aperture camera. We apply a spatio-temporal gradient
based video integration algorithm for fast and accurate in-
tegration of the three input HDR videos into a low dynamic
range video, which is suitable for display. The spatio-
temporal video integration generates videos with temporal
coherency and without artifacts. In order to improve the
computational speed, we propose using a diagonal multi-
grid algorithm to solve the Poisson equation. We show ex-
