Paper Abstract

The color characterization of a DLP (digital light processing) PJ (projection) TV is studied by changing the picture modes. After measuring the chromaticity coordinates, luminance, and spectral radiance of red-green-blue and white as a function of the digital-analog convert value, the contrast ratio, white luminance, chromaticity constancy, channel independency are analyzed. And then colorimetric models for producing desired colors on DLP PJ TV are studied. The performances of GOG (gain-offset-gamma) model and 1-D LUT (look up table) model are evaluated by comparing Δ Eab between measured and predicted values for 56 target colors.
