Anoxia and Brightness Discrimination
1. Brightness discrimination has been studied with individuals breathing oxygen concentrations corresponding to 7 altitudes between sea level and 17,000 feet. The brightnesses were 0.1, 0.01, and 0.001 millilambert involving only daylight (cone) vision. 2. At these light intensities, brightness discrimination begins to deteriorate at fairly low altitudes. The deterioration is obvious at 8,000 f...
متن کاملBrightness Discrimination in Budgerigars (Melopsittacus undulatus)
Birds have excellent spatial acuity and colour vision compared to other vertebrates while spatial contrast sensitivity is relatively poor for unknown reasons. Contrast sensitivity describes the detection of gratings of varying spatial frequency. It is unclear whether bird brightness discrimination between large uniform fields is poor as well. Here we show that budgerigars (Melopsittacus undulat...
متن کاملEffects of Transient Weightlessness on Brightness Discrimination.
Contrast thresholds of six semisupine, visually adapted subjects were obtained under short (10-14 sec.) periods of weightlessness and under 1 G control conditions. The target, viewed binocularly, subtended 1.5 ~ and the background 2.6*. Three background luminance levels were used: 0.03, 0.28 and 30.0 ft-L. The contrast required to detect the target was found to be slightly, but consistently, lo...
متن کاملSpherical Model of Color and Brightness Discrimination
The most important problem confronting color science is the construction of a uniform color space, i.e., a geometrical model of color discrimination in which Euclidean distances between the points representing colors are proportional to perceived color differences. The traditional approach to the construction of a metric color space is based on the integration of just-noticeable color differenc...
متن کاملVision sensor with brightness constancy: towards neuromorphic color vision
A silicon retina is a VLSI (very large scale integration) chip that has been designed based on the neural architecture and functionality of a biological retina. Such devices are expected to be useful as a novel vision sensors for autonomous mobile robots due to their power efficiency, compactness, and real-time processing ability. In addition, their low noise output and wide operating range are...
