Sentence examples for measured luminance from inspiring English sources
The measured luminance is increased as the surface detected by the instrument decreases, up to values higher than 1.0E + 05 cd/m2 when a single led is covered.
The measured luminance, and the saturation values, La*b* coordinates and cone contrasts of the Red and Blue desaturation series are displayed in Table 1.
Spectrometer output was normalized to the measured luminance, resulting after integration across wavelengths in the CIE (1931) XYZ coordinates for each color and also in the La*b* color space coordinates (using Color Converter, version 2.3, http://www.rmimaging.com. In addition, cone contrasts (color vs grey) were calculated from the spectrometric data [45].
Open image in new window Figure 11 Calculated Glare Constant G for measured luminances.
Inlier pixel values (at this 1 pixel, over the set of 50 lights) with estimated L ̂ values that fall within the green inlier band are displayed as black dots and outlier measured luminances, including values with negative luminance estimates that fall below the horizontal line at L=0, as black dots with red crosses.
The method is also useful for characterizing crosstalk in large size active-matrix liquid crystal displays, by measuring luminance changes in small square targets due to variations in the background intensity.
The proposed gamma system contains module-under-test (MUT, LCD module), PC installed with program, multimedia display tester for measuring luminance, and control board for interface between PC and LCD module.
To measure luminance threshold, single and multiunit activity was recorded in the superior colliculus (SC) at approximately P100 using a modification of a previously described procedure [48].
Our night sky brightness data were taken using the "Sky Quality Meter" (SQM) produced by Unihedron (Grimsby, Canada), shown in Figure 2. The SQM measures luminance (surface brightness) for a patch of the sky, in units of magnitudes per square arc second (mag/arcsec2).
A photometer, PhotoResearch PR-650, was used to measure luminance.
