LPBP: low-power basis profile of the Java 2 Micro Edition

Abstract

The Java platform provides a fully fledged programming environment for graphics applications using the Abstract Window Toolkit (AWT). We present a power-aware basis profile of the Java 2 Micro Edition (J2ME) for embedded applications. The low-power basis profile (LPBP) is responsive to backlight luminance scaling in such a way that dynamic adjustment of the backlight luminance is accompanied by adaptive image compensation. The proposed scheme performs aggressive backlight dimming while maintaining the readability of screen contents based on image compensation techniques such as brightness compensation, image enhancement and context processing. Experiments show that on average the LPBP can easily achieve approximately 30% backlight system power reduction.
