Paper Abstract

Light-measurement instrumentation based upon high-quality charge-coupled-devices is currently in use for measuring the characteristics of electronic displays. When such array detectors are used to measure scenes having high contrast or wide color variations, they can suffer from the effects of veiling glare or lens flare and thereby inaccurately measure the darker luminances because of a mixing of the scene luminances or colors. The simulated-dye-design camera attempts to reduce the effects of unwanted light contamination by copying some of the characteristics of the eye. This first prototype shows an improvement of a factor of 2.7 in its ability to measure high contrasts over a similar camera that is not filled with liquid.
