When the luminance level was high, people were more likely to avoid known risks.
The luminance selection process was based on a similar process developed by the International Commission on Illumination (CIE).
As shown in the desaturated version of the RGB rainbow, even the three primary colors, red, green, and blue, vary enormously in luminance: red has a luminance value of about 50, green is about 86, and blue is about 30 (100 would be white).
First, input the geometries of the four elements into the luminance computation model: target vehicle, roadway, sign and other vehicles, as listed in Table 1.
On each trial participants viewed 1 of the 3 disks of different luminance (3.
8,20,21), but also with studies on the changes in sensitivity to second-order stimuli (non-elementary stimuli, defined by changes in features, texture, and depth, and not only by sinusoidal modulation of luminance in space) and studies on changes in perception of contour deformation throughout aging.
The OLED lighting module offers color rendering (CRI>90) suitable for lighting applications, as well as achieving high luminance, high efficiency (17 lm/W), and long lifespan (10,000 hours).
How do the factors of color, viewing angle, and luminance on the windshield affect vision?
In order to develop intelligent street lighting systems that adapt to fog conditions, the propagation of light of different spectral composition and the peculiarities of the formation of luminance patterns of objects in fog of different density are to be known.
diameter and height of the microlens) with very low-surface roughness while showing higher optical performance than small dots fabricated by chemical etching process in view of brightness and uniformity of luminance (L) (6).
Display Search analyzed Sony's XEL-1 OLED TV and determined that, "Lifetime for white at 50 W is calculated to be 5,000 hours with initial luminance of 208 cd/[m.
Change in hue derived from luminance variations (and, consequently, lightness variations) is usually called the "Bezold-Brucke" effect (hereafter the B-B effect).
