Chromaticity and Luminance on Visual Performance and Subjective Performance for Imagery on LCD

This study investigated the effects of chromaticity and luminance on legibility and subjective preference for imagery presented on LCD. The results showed that chromaticity and luminance had little effect on legibility speed. Both chromaticity and luminance significantly affected subjective preference. Chromaticity seemed to be more important than luminance for subjective preference. Participants appeared to prefer medium luminance, they also showed less preference for achromatic imagery. Regression equations for legibility speed and subjective preference were constructed. Correlation analysis showed that the equations were better than Lippert´s ?GE (CIE Y, u´, v´).
