Abstract

A microprocessor controlled tristimulus colorimeter with “notebook” computer data recording and manipulation enables accurate chromaticity measurements. Importance of exact colorimetric mapping of the Video Display Units (VDUs) prompted the development of CCD camera-tristimulus filter colorimeters. Characterization of CCDs for spectral response and pixel to pixel uniformity precedes the filter design. The paper will show attainable accuracy; discusses problems arising from pixel to pixel variation of spectral responsivity and its partial correction by matrix transformation of the tristimulus values.
