| Abstract |
|
Transient chromatic adaptation produced by an abrupt change of background color permits an easier and closer approach to cone isolation than does steady-state adaptation. Using this technique, we measured middle-wave-sensitive (M-) cone spectral sensitivities in 11 normals and 2 protanopes and long-wavelength-sensitive (L-) cone spectral sensitivities in 12 normals and 4 deuteranopes. Although there is great individual variation in the adapting intensity required for effective isolation, there is little variation in the shape of the M- and L-cone spectral-sensitivity functions across subjects. At middle and long wavelengths, our mean spectral sensitivities agree extremely well with dichromatic spectral sensitivities and with the M- and L-cone fundamentals of Smith and Pokorny \[Vision Res. 15, 161 (1975)\] and of Vos and Walraven \[Vision Res. 11, 799 (1971)\], both of which are based on the CIE (Judd-revised) 2{\textdegree} color-matching functions (CMF's). But the agreement with the M-cone fundamentals of Estévez \[Ph.D. dissertation, Amsterdam University (1979)\] and of Vos et al. \[Vision Res. 30, 936 (1990)\], which are based on the Stiles-Burch 2{\textdegree} CMF's, is poor. Using our spectral-sensitivity data, tritanopic color-matching data, and Stiles's $\pi$3, we derive new sets of cone fundamentals. The consistency of the proposed fundamentals based on either the Stiles-Burch 2{\textdegree} CMF's or the CIE 10{\textdegree} large-field CMF's with each other, with protanopic and deuteranopic spectral sensitivities, with tritanopic color-matching data, and with short-wavelength-sensitive (S-) cone spectral-sensitivity data suggests that they are to be perferred over fundamentals based on the CIE 2{\textdegree} CMF's.
