Abstract

Mobile devices have become an indispensable part of our live. Hence, to increase the battery life of mobile devices has become a crucial research topic to interdisciplinary fields. In this paper, we propose a subjective-visual-perception-based (SVPB) OLED displays dimming technique to reduce the power consumption when displaying videos on mobile devices. First, we extract the motion vectors (MV) from the video's bitstream and transform it into a saliency map. Then, we formulate an SVPB pixel dimming algorithm to obtain how great of pixel's value can be reduced with respect to its intensity of salience, based on the principle of human visual system (HVS). Finally, a subjective experiment is conducted to determine the parameter in the algorithm to ensure the good visual quality. Experimental results show that our method achieved on average 16% of power-saving.
