Pages: 371 - 388
High dynamic range (HDR) and wide color gamut video processing have started to receive significant research attention in recent years, especially in relation to content generation and processing. However, displaying such content is still a challenge, and efforts are required to make their deployment possible at consumer levels. While the emergence of locally backlit displays has helped to achieve higher contrast in the display of traditional low dynamic range videos, their use for displaying HDR videos is nontrivial. This chapter, therefore, aims to first identify a few challenges in this area. It then outlines a new dual modulation algorithm for the rendering of HDR content. It also discusses practical lessons that can be helpful toward the rendering of more accurate and visually appealing HDR content. © 2016 Elsevier Ltd All rights reserved.
