Course Instructor
SC1097: HDR Imaging in Cameras, Displays and Human Vision
High-dynamic range (HDR) imaging is a significant improvement over conventional imaging. After a description of the dynamic range problem in image acquisition, this course focuses on standard methods of creating and manipulating HDR images, replacing myths with measurements of scenes, camera images, and visual appearances. In particular, the course presents measurements about the limits of accurate camera acquisition and the usable range of light for displays of our vision system. Regarding our vision system, the course discusses the role of accurate vs. non-accurate luminance recording for the final appearance of a scene, presenting the quality and the characteristics of visual information actually available on the retina. It ends with a discussion of the principles of tone rendering and the role of spatial comparison.
