碩士 === 國立中正大學 === 光機電整合工程研究所 === 102 === In this study, we focus on evaluating lighting source’s relationship between correlated color temperature and brightness.We use multi-spectral imaging technique to simulate 24 color patch’s image with different correlated color temperature and illuminace under RGB LED and CIE standard illuminant. According to CIE 116, we use the simulated image which uses CIE standard illuminant D65 with illuminance at 400 lux as our basis to calculate color difference with other simulated image in order to find the relationship between correlated color temperature and brightness.These simulated images can provide observers with visual perception.Finally, after two simulated images which use high CCT light source with lower illuminance and low CCT light source with higher illuminance light source compare with a simulated image which uses CIE standard illuminant D65 with illuminance at 400 lux,we can find these simulated images have same color difference and visual perception.
