| Abstract | ||||
| The colors displayed on an outdoor LED Display appear incorrectly most of time due to the contieously changing ambient lighting conditions. In this paper, we demonstrate the MACCLED (Mixed Adaptive Color Correction) system that correct the displayed colors on the LED display based on the readings from both ambient color sensor and a photometer. The performance of the system is then analyzed through conducting a series of psychophysical visual experiments. The resulting z-score of each ambient conditions is then compared to select the optimum adjustment of system parameters. | ||||
