摘要：Outdoor LED Displays is the most used display technology in outdoors due to it high luminance output capabilities. In such case the observers eyes try to adapt to the ambient lighting surrounding the display which is continuously changing through the day. This result in the actual perceived adapted colors from the display suffer major discrepancies when compared to the target color in the displayed media. In this paper, we propose a model for the outdoor LED display that suffers from flares reflections. Then we modify the model based on the mixed chromatic adaptation model developed by the CIE TC8-4 committee. Next a reverse model is developed to predict new color values in order to appear matching to the original target colors. Finally, we evaluate the model performance and investigate the effect of varying model parameters trough psychophysical experiments.
