Paper Abstract

An analysis of the performance of a cathode-ray-tube flying-spot-scanner film reading system requires a treatment of the gray level resolution of the system. This paper discusses three types of gray level encoding schemes for a digital film reading system; equal transmission, equal density and equal reliability levels. The maximum number of detectable levels, or the minimum gray level change detectable, to a given reliability is presented along with a trade-off analysis and a discussion of the utility of each method. Calibration and measurement of a hardware system by analysis of maximum signal available is discussed.
