Abstract
The mobile terminal as a phone or a pad would be influenced by the ambient illumination when it was used in different scenarios. In order to keep good visibility, the screen backlight luminance needs to be adjusted in accordance with the ambient illumination. The high ambient lighting conditions were taken into account in this paper to find out a more universal Auto-Brightness Control (ABC) technology. The perceptual brightness of 20 test images displayed on the mobile phone were visually evaluated via categorical judgment method under six levels of ambient illumination (from dark up to 20000 lx) with six levels of screen backlight luminance. The experimental results show that the score of perceptual brightness and ambient contrast ratio (ACR) were in logarithmic relation, which has stronger relation with optimum luminance of mobile terminal. Therefore, a new ABC Technology was proposed to automatically adjust the display luminance in mobile devices to maintain visibility under various ambient illumination.
