A Color Gamut Assessment Standard: An Inter-Laboratory Measurement Comparison

Abstract

In earlier papers, NIST proposed a standard illumination source and optical filter targets to with which to assess the state-of-the-art of display measurement. The Gamut Assessment Standard (GAS) was present the display metrologist with a set of transmission targets such as interference, colored glass, and neutral density filters, back-lighted by a standard illumination source to be measured using methods and instruments typically used in display performance measurement. A 'round robin' interlaboratory measurement exercise using the 'standard' artifact suite would enable a 'first order' assessment of color measurement reproducibility among the display measurement community. In the first phase of interlaboratory comparison, the GAS was measured by three national measurement institutes (NMIs) in order to 1) identify potential problems with the design of the device or of the measurement protocol; and 2) to provide a baseline measurement of reproducibility against which to evaluate a more extensive intercomparison. The talk will describe the results of the NMI intercomparison; discusses measurement issues such as stability of the illumination source and outlines the NIST plan to begin circulating GAS units to the next tier of intercomparison participants, the instrument manufacturers. Plans for a robust source for the GAS will also be presented.
