Spectral sensitivities of the human cones

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 variati… Show more

“…This confirms the conclusions using high-color backgrounds (Conway, 2001). High-color backgrounds may provide more reliable estimates of the cone inputs because "transient chromatic adaptation produced by an abrupt change of background color permits an easier and closer approach to cone isolation than does steadystate adaptation" (Stockman et al, 1993). In any event, the receptive-field structure of single double-opponent cells remains relatively stable using both methods (Conway, 2006) and predicts that the neurons will respond optimally to adjacent patches of oppositely colored light (e.g., red next to green).…”

“…Spectral and gamma curves were measured at 4 nm intervals in the 380 -770 nm range using a photospectrometer (PR-650; Photoresearch, Chatsworth, CA). Stimulus cone contrasts were calculated using the 2°Stockman fundamentals (Stockman et al, 1993), which incorporate the macular pigment absorption effects. Because our stimuli were within 3°eccentricities, no correction for macular pigment was necessary.…”

“…One may compute cone coordinates or XYZ tristimulus coordinates from the spectral power distributions measured by spectroradiometers. If one wishes to use a description of color vision that differs from that specified by the CIE system (e.g., 24,25,27,42,62,63), then it is necessary to characterize the display by using a spectroradiometer. However, spectroradiometers are expensive (thousands of dollars), whereas colorimeters often cost less than a thousand dollars and the XYZ measurements they provide are sufficient for many applications.…”
