“…Up to that point, around 10m away, the necessary luminances range from 687 cd/m2 to around 10000 cd/m2 (assuming we only consider distances 300m and below). A typical CRT has a luminance of 50 to 100 cd/m2, modern LCD displays around 200 to 600 cd/m2, with only experimental displays with individually controlled LED backlights (for high dynamic range images) capable of 10000 cd/m2 (Seetzen et al, 2004). Thus, current display technology cannot yet achieve the necessary luminance to create realistic headlight glare directly on the screen.…”

Summary:We report on the development of a realistic dynamic simulation of oncoming headlamp glare in a driving simulator. To our knowledge, no such simulation had been attempted or achieved previously. The simulation is based on superposition of a bright LED display through a beam splitter on the simulator screen and synchronizing the illuminated LED position to the image of the simulated oncoming car. LED brightness is adjusted to result in the level of light that such headlights would cause in the driver's eyes, enabling the testing of glare effect on drivers of different ages and impact (reduction or increase) of various vision devices.

“…This, together with software correction algorithms that took into account how the human eye perceives light scattering, provided a substantial increase in dynamic range. The DR37-P display was capable of a dynamic range of 16 f-stops [9]. …”

“…A breakthrough for capturing HDR images came with Debevec and Malik's paper in 1997 [8], which clearly demonstrated how an HDR image could be captured from a series of LDR exposures using knowledge of the camera response curve. It would still, however, be many years before the first displays capable of displaying HDR video (2004) [9], or HDR video cameras (2009) [10] would appear.…”

High Dynamic Range (HDR) video has emerged from research labs around the world and entered the realm of consumer electronics. The dynamic range that a human can see in a scene with minimal eye adaption (approximately 1,000,000 : 1) is vastly greater than traditional imaging technology which can only capture about 8 f-stops (256 : 1). HDR technology, on the other hand, has the potential to capture the full range of light in a scene; even more than a human eye can see. This paper examines the field of HDR video from capture to display; past, present and future. In particular the paper looks beyond the current marketing hype around HDR, to show how HDR video in the future can and, indeed, should bring about a step change in imaging, analogous to the change from black and white to colour.

“…Modern displays can now show much higher dynamic ranges than before [25,19]. This has given rise to the inverse problem: how to correctly visualize legacy LDR content on these modern displays, for which the data range needs to be expanded.…”

As the dynamic range of displays keeps increasing, there is a need for reverse tone mapping methods, which aim at expanding the dynamic range of legacy low dynamic range images for viewing on higher dynamic range displays. While a number of strategies have been proposed, most of them are designed for well-exposed input images and are not optimal when dealing with ill-exposed (under-or over-exposed) content. Further, this type of content is more prone to artifacts which may arise when using local methods. In this work, we build on an existing, automatic, global reverse tone mapping operator based on a gamma expansion. We improve this method by providing a new way for automatic parameter calculation from the image statistics. We show that this method yields better results across the whole range of exposures.
