Abstract

Several approaches attempt to reproduce the appearance of a scotopic low-light night scene on a photopic display (“dayfor- night”) by introducing color desaturation, loss of acuity and the Purkinje shift towards blue colors. We argue that faithful stereo reproduction of night scenes on photopic stereo displays requires manipulation of not only color but also binocular disparity. To this end, we performed a psychophysics experiment to devise a model of disparity at scotopic luminance levels. Using this model, we can match binocular disparity of a scotopic stereo content displayed on a photopic monitor to the disparity that would be perceived if the scene was actually scotopic. The model allows for real-time computation of common stereo content as found in interactive applications such as simulators or computer games.
