Make Image More Energy Efficient for Mobile OLED Displays
Energy consumption of mobile devices has become an important consideration due to the limitation of battery capacity, and OLED displays are the dominant energy consuming component of battery operated devices. Since its energy consumption depends on the displayed content, in this work we propose a new energy saving approach to make image more energy efficient for mobile OLED displays. The key idea is to eliminate undesired details while preserving the region of interest of the image by leveraging the color and spatial information. First we use edge detection algorithm to extract region of interest (ROI) of an image, and then we gradually adjust luminance and saturation of region of non interest (NON ROI) of the image, which can reduce significant amounts of energy consumption while preserving the image quality. Experimental results show that our approach can save 22% energy on average, which demonstrates the effectiveness and efficiency of our approach.
