A new approach to imaging colorimeter design has been demonstrated. This approach is based on the concept of spectrally adaptive filtering of images, which permits adjustment of the overall response of the system for measuring color coordinates to fit one of three color matching functions and to change its spectral response rapidly. The experiments conducted demonstrated high spatial resolution -- 512 by 512 pixels or more (for nonpixelated objects), capability of performing color coordinate measurements of an entire image in 1/30 second, and high measurement accuracy.
