Abstract

Taking the chromaticity inconstancy of LCDs and the inverse efficiency into account, a novel local colorimetric characterization model was developed in this Letter. Rather than dividing the device color space into many subspaces to refine the chromaticity description as existent local models, the proposed model tailored the transformation relationship uniquely for each characterized color with look-up tables and a local chromaticity matrix. Based on this model, the characterization task could be efficiently accomplished within a few steps for either the forward or the inverse transformation. Test experiments on several commercial LCDs indicated that the average color difference between the estimated and measured tristimulus values could be achieved in a low level of about 0.4 CIEDE2000 units, effectively demonstrating the proposed model.
