Video quality metric model of MSE for backlight power saving

Abstract

The backlight power saving for LCD is an important research topic, since the backlight is the main source of energy consumption. Typically, the backlight power saving is done by limiting the dynamic range of the displayed pixels; the image quality will decreased. And how to maintain the image quality becomes the important issue. In this work, we propose to use a well-known video quality metric called VQM (Video Quality Metric) to measure the video quality, and proposed a VQM curve to be predicted by the MSE (Mean Square Error). This proposed curve can later be used to efficiently maintain the video quality while performing the backlight power saving.
