Abstract

Measurement of a small black area on a white electronic display screen is often accompanied by serious contamination from veiling glare in the detector. The black measurement can be thousands of percent in error. Character-stroke-contrast or small-area-contrast measurements are greatly improved by using a replica mask of known luminance even in uniform ambient conditions.
