Abstract

The use of mobile devices is rapidly growing each year due to their portability and convenience. User experience and battery life are both crucial topics in the advancement of these devices. Sensing the light environment of a mobile device and adapting the output of the device accordingly can create positive results for both user experience and battery life. In this paper, we concentrate on different levels of ambient luminance and its influence on the viewing experience of the user. Since the human visual system is less sensitive to video noise at higher levels of ambient luminance, under those conditions we allow more noise to achieve power consumption reduction. Through subjective testing we show that in general our method works well for attaining a good quality of experience to the user. The hardware simulation for our design results in 32.6% power savings.
