Characteristics of the Human Eye 167
Figure 8.9 The standard relative luminosity factors (relative sensitivity or response)
for photopic and scotopic conditions.
Figure 8.10 The spectral response of the human eye. The solid
lines are the photopic (daylight) response, and the dashed lines
are the scotopic (dark-adapted) response. There are two curves
for each response: one is the relative response at the indicated
wavelength; the other is the (integrated) fraction of the response
for wavelengths shorter than that indicated.
