Image display algorithms for high‐ and low‐dynamic‐range display devices

Abstract

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.
