A look-up table algorithm is described for enhancing the luminance resolution at the expense of the colour resolution in digital displays of colour images. For colour displays with a look-up table resolution of 8 bits/gun, the algorithm provides a luminance resolution of 11-12 bits without loss of spatial or temporal resolution. This improvement can reduce the minimum luminance step in the mid-luminance range from 1.5% to > 0.2% with no additional hardware. 

Topics from this paper

The noisy-bit method for digital displays: Converting a 256 luminance resolution into a continuous resolution
TLDR
It is concluded that the noisy-bit method, combined with the standard 256 luminance levels, is perceptually equivalent to an analog display with a continuous luminance intensity resolution when the spatiotemporal resolution is high enough that the noise becomes negligible. Expand
Rapid Assessment of Contrast Sensitivity with Mobile Touch-screens
TLDR
A novel method in which subjects use a finger swipe to indicate the transition from visible to invisible on a grating which is swept in both contrast and frequency is described. Expand
Perceptual Fidelity for Digital Image Display
TLDR
A method whereby the display device itself can be used to determine the effect of ambient light on perceived contrast, thus enabling the viewers themselves to perform visually-based calibration, which is grounded in established psychophysical experimentation. Expand
Photometric and colorimetric measurements of CRT and TFT monitors for vision research
Visual displays have various limitations that can affect the results of vision research experiments. This study compares several characteristics of CRT (Hewlett Packard 7650) and TFT (LG Flatron L227Expand
17.3: Visual Calibration of Displays for Accurate Contrast Reproduction
TLDR
A visual calibration method (free of instruments) to characterize color display response is developed, and its capability to produce wide dynamic range achromatic display accurately as needed for measuring contrast sensitivity is demonstrated. Expand
Psychophysical contrast calibration
TLDR
This work developed and evaluated a novel method that uses only psychophysical responses of a person with normal vision to calibrate the luminance contrast of displays for experimental and clinical applications, enabling clinical, internet and home implementation and calibration verification of electronic contrast testing. Expand

TLDR
This work developed and evaluated a novel method that uses only psychophysical responses of a person with normal vision to calibrate the luminance contrast of displays for experimental and clinical applications, enabling clinical, internet and home implementation and calibration verification of electronic contrast testing. Expand
Perceptual display calibration
A good display design should make the inaccuracies and limitations of a display technology invisible to the human eye. However, this requires a good understanding of what is and what is not visibleExpand
A Method for Rapid Measurement of Contrast Sensitivity on Mobile Touch-Screens
TLDR
This work was motivated by the idea that a method for performing a quick assessment of vision in a minute or two could enable weekly or even daily monitoring of astronaut vision, and good agreement with estimates obtained from traditional psychophysical methods as well as newer rapid estimation techniques is shown. Expand
Visual calibration and correction for ambient illumination
TLDR
A method whereby the display device itself can be used to determine the effect of ambient light on perceived contrast, thus enabling the viewers themselves to perform visual calibration, so that the contrast of an image view in bright conditions can be corrected to appear the same as an image viewed in a darkened room.

Transfer of spatial chromaticity-contrast at threshold in the human eye.
TLDR
It is inferred that spatial interactions are different in the chromaticness and brightness channels of the visual system and a decrease of the luminance level causes an increase of the neural integrative interaction of the color signals. Expand

TLDR
The criterion of minimally distinct border is compared with the criteria of minimum flicker and equal brightness for assessing the luminance of a chromatic field and the results suggest that minimally separate border should be used as the criterion, not equal brightness. Expand
