The relation of lightness and stereoscopic depth in a simple viewing situation. Individual variations in the spatial profile of human macular pigment. Density of the human crystalline lens is related to the macular pigment carotenoids, lutein and zeaxanthin. Percentage of blackness as a function of disparity. Two regression lines intersect the data points of each contrast condition, one for positive disparities and the other for negative disparities.
All functions approximate zero slope.
The date are averages for all subjects. This figure shows that lightness is independent of stereoscopic depth.
