The dynamic range of the human visual system should be an important parameter in the design of high dynamic range (HDR) display devices. A good display should at least approximate this range. However, the literature reports a simultaneous dynamic range between 2 and 4 log units of luminance, leaving ambiguity as to what dynamic range HDR display devices should cater for. In this paper we present a sequence of psychophysical experiments, carried out with the aid of a high dynamic range display… 
An assessment of simultaneous dynamic range for HDR rendering
High dynamic range (HDR) image rendering has been an active research area in the last two decades. In real-world scenarios, there is a wide range of luminance (around 14 log units) between highlights
41.1: Distinguished Paper: Viewer Preferences for Shadow, Diffuse, Specular, and Emissive Luminance Limits of High Dynamic Range Displays
Though there is some variability in preferred brightness between certain demographics, the call for a more capable display is still evident, as preferred luminances found in this study exceed even the best of consumer displays today.
The perceived intra-frame dynamic range in a cinema environment
When considering a higher contrast and brightness range in cinema, it's important to understand the limits of the Human Visual System (HVS) under cinema specific conditions. A user experiment with 36
Visual masking phenomena with high dynamic range content
This paper presents two psychovisual experiments that were carried out with the aid of a high dynamic range display, in order to determine potential differences between Standard Dynamic Range (SDR) and HDR edge masking (EM) and luminancemasking (LM) effects.
Physical and Perceptual Limitations of a Projector-based High Dynamic Range Display
A projector-based HDR display is described, giving details on its hardware components and software for driving and calibrating the display, and the colorimetric properties of the display are reported: the colour reproduction accuracy, colour gamut and local contrast dependent on the size of displayed checkerboard pattern.
Perceptual Uniformity for High Dynamic Range Television Systems
An HDR television system is proposed that supports the highest quality HDR images with a simultaneous dynamic range substantially beyond the limits of the human visual system in a single adaptation state.
This paper presents an HDR VR demonstrator with a display system comprised entirely of off-the-shelf parts, capable of peak luminances over 16,000 nits, which has the potential to achieve a higher degree of perceptual realism than existing direct-view devices like HDR televisions and other high-luminance prototypes.
Preference limits of the visual dynamic range for ultra high quality and aesthetic conveyance
A subjective study was conducted to investigate the preferred maximum and minimum display luminances in order to determine the dynamic ranges for future displays, and concluded that even the average preferred maximum luminance for highlight reproduction is ~4,000 cd/m2.
An Analysis of Visual Adaptation and Contrast Perception for Tone Mapping
This work proposes a tone mapping operator with two stages that implements visual adaptation and local contrast enhancement, based on a variational model inspired by color vision phenomenology, and compares very well with the state of the art.


Do HDR displays support LDR content?: a psychophysical evaluation
This work has carried out a series of rigorous psychophysical investigations to determine how LDR images are best displayed on a state-of-the-art HDR monitor, and to identify which stages of the HDR imaging pipeline are perceptually most critical.
Increment thresholds in a subject deficient in cone vision
It is well recognized that measurements of visual function at different levels of illumination generally fall into two categories, a low intensity scotopic portion and a high intensity photopic portion, and in the time course of dark-adaptation, in the curves where log.

The psychophysical technique was significantly improved to provide more reliable estimates of color appearance as a function of adaptation duration, and the time course of chromatic adaptation was measured for six chromaticity changes, suggesting two stages of adaptation.
A model of visual adaptation for realistic image synthesis
A computational model of visual adaptation for realistic image synthesis based on psychophysical experiments that captures the changes in threshold visibility, color appearance, visual acuity, and sensitivity over time that are caused by the visual system’s adaptation mechanisms.
Video viewing preferences for HDR displays under varying ambient illumination
It is found that subjects experienced minimal visual fatigue, and also found statistically significant differences in preferred display settings under different ambient lighting conditions.
Display considerations for night and low-illumination viewing
A display design is tested in which the spectral light emission is selected to reduce the impact of the display on night vision performance while at the same time ensuring good display legibility.

The regularity of the rise of liminal test stimulus with decrease of the interval between it and the conditioning stimulus precludes any purely psychological explanation, and the effect is presumed to be due to some nervous interaction in the higher centres of visual reception.
Spatial Modulation Transfer in the Human Eye
The contrast sensitivity of the human eye for sinusoidal illuminance changes was measured as a function of spatial frequency, for monochromatic light with wavelengths of 450, 525, and 650 nm. At each
What does the eye see best?
It is shown here that, within the range that the authors have been able to test, there is a particular spatiotemporal pattern of light that is detected better than any other, and it is proposed that this is the weighting function of the most efficient human contrast detector.
54.2: A High Dynamic Range Display Using Low and High Resolution Modulators
This paper provides a description of the technology as well as findings from a supporting psychological study that establishes that correction for the low resolution display through compensation in the high resolution display yields an image which does not differ perceptibly from that of a purely high resolution HDR display.
