The influence of spectral bandpass on accuracy of tristimulus data

The influence of spectral bandpass on accuracy of tristimulus data When calculating tristimulus values from spectral radiance factors which were measured with a spectral bandpass of 10 nm, using data from the same specimen measured with a spectral bandpass of 1 nm and calculated with a 1‐nm interval as standard, and evaluating the significance of the difference in tristimulus values with the CIELAB color difference formula, it is highly probable that a 1‐nm calculation interval will give no greater accuracy than a 10‐nm calculation interval. For this reason it is recommended that the CIE reconsider their approval of the deletion of the 10‐nm calculation interval from the new edition of Publication CIE 15. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Color Research & Application Wiley

Abstract

When calculating tristimulus values from spectral radiance factors which were measured with a spectral bandpass of 10 nm, using data from the same specimen measured with a spectral bandpass of 1 nm and calculated with a 1‐nm interval as standard, and evaluating the significance of the difference in tristimulus values with the CIELAB color difference formula, it is highly probable that a 1‐nm calculation interval will give no greater accuracy than a 10‐nm calculation interval. For this reason it is recommended that the CIE reconsider their approval of the deletion of the 10‐nm calculation interval from the new edition of Publication CIE 15.
