The luminance value for the surface photons was calculated by taking an area average over a small circular region covering neighboring photons.
As luminance values of glare sources get extremely high, the impact of the absolute luminance value begins to dominate the impact of the contrast ratio.
The feasibility of the designed model was checked with simulation, which calculates luminance value over the LGP surface based on ray tracing technique, and the obtained results were analyzed to determine optimized fabrication conditions in experimental implementation.
Stable warm white light emission with Commission International de L'Eclairage CIEE) coordinates from (0.37, 0.45) to (0.38, 0.47) for a luminance value ranging from 1000 to 10,000 cd/m2 was obtained.
Since the intended luminance value of each point in the scanning pattern is transmitted by the methods of monochrome television, it is only necessary to transmit, via an additional two-valued signal, supplementary information giving the hue and saturation of the intended colour at the respective points.
Let F ̄ k be the mean luminance value for the k th frame and B ̄ k ( i, j ) the mean luminance value of block B k ( i, j ).
In cases when video-level controller uses only AVG measurement, it tunes camera parameters to make the measured average luminance value equal to the desired average luminance value.
Generally, blotches having almost uniform luminance value are likely to have small areas.
Daylighting design standards in China are based on the natural daylighting luminance value.
Also, we can see that the luminance value varies on the position.
As mentioned above, 255 of luminance value is produced by two kinds of situation.
