  • Title: Toward a CIE supplementary system of photometry: brightness at any level including mesopic vision.
    Author: Sagawa K.
    Journal: Ophthalmic Physiol Opt; 2006 May; 26(3):240-5. PubMed ID: 16684150.
    Abstract:
    Photometry for brightness at any level including mesopic vision is described on the basis of the work conducted towards the development of a Commission Internationale de l'Eclairage (CIE) supplementary system of photometry in CIE technical committees. Several critical items in developing such a system are discussed: (1) how to scale brightness using the concept of equivalent luminance; (2) the basic vision model of brightness perception; (3) a description of the chromatic contribution to brightness at the photopic as well as at the mesopic level; (4) formulation of an adaptation coefficient for rod-cone interaction. A possible photometric model for brightness is described based on these considerations, together with a quantitative evaluation of the model using experimental data.
