Paper Abstract

This study presents effective method to provide user’s visual comfort and reduce power consumption through the optimization of display luminance and gamma curve for using mobile display in low ambient conditions. Visual assessment was carried out to obtain appropriate display luminance for visual comfort, and gamma curve was optimized to obtain power saving effect without reducing image quality in lower luminance than in appropriate luminance. This suggested method was verified through perceptual experiment and power consumption measurement.
