Estevez, O. Walraven, P.L. Instituut voor Zintuigfysiologie TNO Publication year 1990 Abstract New action spectra are derived for the foveal cones on the basis of three assumptions: (1) the Stiles-Burch (1959) colorimetric data are better than CIE 1931; (2) the long wavelength flanks of the dichromatic luminosity functions offer better anchorage than the confusion loci; and (3) the relative mutual heights per receptor can be derived from the Bezold-Brucke effect. Since these assumptions do not include photometric data, we could at the end ask how L(λ), M(λ) and S(λ) combine to V(λ). The best answer appeared to be V(λ) = 0.68 L(λ)+ 0.34 M(λ) - 0.02 S(λ), reflecting both relative population densities and a negative input of the S-system to luminance.benzold-brucke effect - cone Subject Visionaction spectraadditivityBenzold-Brucke effectconefovealuminancearticlecolor visionhuman experimentilluminationnormal humanpriority journalretina foveavisionvisual systemColor PerceptionColorimetryFovea CentralisHumanMathematicsModels, BiologicalPhotometryPhotoreceptorscoloureyeluminancecolour vision To reference this document use: http://resolver.tudelft.nl/uuid:7680c119-f91f-4e74-a34c-cd781fe1a8fa DOI https://doi.org/10.1016/0042-6989(90)90059-t TNO identifier 6925 Source Vision Research, 30 (6), 937-943 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
