Chromatic Adaptation Model for Incomplete Chromatic Adaptation

When the adaptation level is not high enough, the maximum adaptation stimulus is not equal with the plot of illuminant. This property is accepted in this paper. Using this property, we propose a chromatic adaptation model for the level of adapting luminance and chromaticity in various surrounding illuminants. In this model, we calculate the maximum adapting responses using adapting degree for viewing conditions, and then we can reproduce from the original color to the corresponding color using the ratio of maximum adapting response between different viewing conditions. The proposed model will be able to guarantee reliability with stable performance and to easily be embodied as a linear model.
