In most display applications, the final step is the viewing by human observers, so it is only logical to use current quantitative knowledge of the visual system in the design of imaging and display algorithms. This talk will cover key human visual system attributes, their modeling as separate components, and how they have been used in our labs to design new display algorithms and fine‐tune existing approaches. Some of the resulting algorithms described will include: motion‐adaptive backlight flashing, skin‐cognizant color mapping, two‐spatial channel architecture for color mapping and decontouring, bit‐depth extension, subpixel subsampling, and wavelet compression. The talk will also cover the new challenges that arise in very large (>100″) and bright (>500 cd/m∧2) displays, in terms of peripheral sensitivity and improved smooth pursuit eye movement capability.
