A closer look at the tritanopic convergence point

摘要: On the basis of new experimental data tritanopic vision convergence centre for tritanopia has been redetermined, and turned out to bex' = 0.1747,y' 0.0060 in Judd 1951-chromaticity diagram. A consequence this determination is that blue system more sensitive than was concluded from Thomson-Wright (1953) study. The spectral sensitivities three colour mediating systems are derived. ratio number “red”, “green” “blue” receptors normal trichromatic eyes derived be 32:16:1.
