Analysis of the proposed IEC “Color Light Output” digital projector specification metric, using CIELAB gamut volume

“Color Light Output” is a proposed specification metric for IEC 61947-1 (Electronic projection – Measurement and documentation of key performance criteria – Part 1: Fixed resolution projectors) The study evaluates the performance of the color illuminance metric by testing a sample of popular digital projectors in the business and education category. The study confirms the utility of the color illuminance metric as a predictor of perceived color gamut and total projector performance.
