Sentence examples for array of luminance from inspiring English sources

where: I lum is an array of luminance values, K Z y is a vertical coordinate of the outer corner, and S i is the initial value of the ith interval (i = 1 … 5).

– In line with this hypothesis, previous studies found an effect of perceptual difficulty on dwell times [8]: For instance, when observers have to search for a letter in an array of 10×10 letters, increasing the luminance contrast of all stimuli significantly decreased mean dwell times, from 251 ms in the lowest contrast condition, to 194 ms in the highest contrast condition [8] [10].

Using the Integral Image, any sum of luminance within a rectangle can be calculated from II using four array references (Figure 4).

Inappropriate spatial distribution of luminance.

The use of luminance images brings us multiple benefits.

The PLEDs have a feature of luminance characteristics.

where R l denotes the range of luminance intensity.

We investigate the effect of luminance filtering in Section 5.4.

The luminance values inside the oval mask were normalized for each face such that mean luminance was equal to half maximum luminance (i.e., 35 cd/m2), and the root-mean-squared (rms) contrast (defined as the standard deviation of luminance divided by mean luminance) was set to 1. Luminance outside the oval mask was set to half the maximum luminance.

The Effect of Luminance Distribution.

The MP-1S is also equipped for scotopic use with a couple of additional filters that extend the dynamic array of the instrument luminosity to the very subdued illumination conditions required: the first one consists of a 2.0 log unit neutral filter that annuls the 4 asb of luminance of MP-1 mesopic and, therefore, reduces screen luminance.
