Image Display Algorithms For High- And Low-Dynamic-Range Display Devices

Abstract

With interest in high-dynamic-range imaging mounting, techniques for displaying such images on conventional display devices are gaining in importance. Conversely, high-dynamic-range display hardware is creating the need for display algorithms that prepare images for such displays. In this paper, the current state of the art in dynamic-range reduction and expansion is reviewed, and in particular the theoretical and practical need to structure tone reproduction as a combination of a forward and a reverse pass is passed. © Copyright 2007 Society for Information Display
