Neutral Point Model Adapted for the Variations of the Luminance

In this paper, we propose the Luminance-Adapted Neutral Point Model, LANPM, for the variations of the luminance levels under the same illuminant. LANPM is modeled by the transform between the other luminance levels. In the model, the optimal coefficients are obtained from the Hunt’s experimental result. The gain coefficient of the conventional chromatic adaptation model is taken to be the L, M and S cone responses for the scene white stimulus. However it is applied in the chromatic adaptation model using gain coefficients for the neutral point of the various viewing conditions. And the LANPM can be used as the theoretical standard which determines the reference white of the color display devices.
