Colorimetry system for display testing

The invention relates to an improved method for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing, comprising: - directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; - transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; - directing a second portion of the light to a colorimeter which produces second tristimulus values; - deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and - applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values; and an imaging colorimeter system capable of two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample.
