Real Time Automated Tone Mapping System for HDR Video
Chris Kiser, Erik Reinhard, Mike Tocci, Nora Tocci · 2012
Tone Mapping of HDR Images has been studied extensively since the introduction of digital HDR capture methods. However, until recently HDR video has not been realized in a viable form as that given by Tocci et al.[1], which will lead to readily available HDR video cameras. Because they capture video with much broader dynamic range than can currently be displayed, these cameras present a unique challenge. In order to maintain backward-compatibility with legacy broadcast, recording, and display equipment, HDR video cameras need to provide a real-time tonemapped LDR video stream without the benefit of post-processing steps. The purpose of this research is to present a complete TMO solution that can be implemented in real time hardware to yield a high-quality automated LDR video stream suitable for direct use by today’s recording, broadcast, and display equipment.
