Sentence examples for ambient luminance from inspiring English sources
During LD, after the initial TMS measurements under standard room lighting conditions (530 lux), ambient luminance was reduced to a level just sufficient for the investigator to perform TMS; subjects wore opaque goggles and reported complete absence of perceived light.
Reflection measurements include specular and diffuse reflection coefficients from which the maximum allowable ambient lighting is determined such that contrast degradation due to display reflection remains below a 20% limit and the level of ambient luminance (Lamb) does not unduly compromise luminance ratio (LR) and contrast at low luminance levels.
Masking modulates vital status with time by detecting ambient luminance [8], [9]; for example, nocturnal animals are active when the surroundings are dark (<∼0.2lx; positive masking) and passive in a brighter milieu (>∼10lx; negative masking) [21].
Our results clearly indicate that the masking effects that ambient luminance and temperature exert on locomotor activity have been selected as key proximate mechanisms to shape the temporal niche of owl monkeys within a gradient between nocturnality and diurnality.
To test whether nocturnal locomotor activity in A. azarai in its natural environment may represent a case of positive masking by moonlight, we analyzed the relationship between locomotor activity and ambient luminance as measured in an open savannah area in front of the monkeys' gallery forest habitat.
We use continuous long-term (6 18 months) 5-min-binned activity records obtained with actimeter collars fitted to wild owl monkeys (n = 10 individuals) to show that this different pattern results from strong masking of activity by the inhibiting and enhancing effects of ambient luminance and temperature.
In this case, MEMS control both luminance and color, and when ambient light is high enough, the backlight can be shut off completely and the screen will work like an e-paper one.
The dark condition was ambient light.
Consider as an example an experiment to investigate the influence of physical attributes of the work environment such as luminance, ambient temperature and relative humidity on human performance of acceptance inspection in quality assurance.
This would explain our findings and supports our hypothesis that vision in the harbour seal is purely scotopic at an ambient and stimulus luminance of 0.5 and 2 cd/m, respectively.
