基于局部均值和标准差的LCD动态背光调整
Dynamic Backlight Adaptation Based on Local Mean and Standard Deviation for LCD
摘要
Abstract
In order to cut down the power consumption of LCD backlight and maintain the image quality, a modulation algorithm based on Local Mean (LM) and Local Standard Deviation (LSD) is proposed. The algorithm can dim the luminance of backlight effectively in dark and low contrast blocks and maintain the image quality in the bright and high contrast blocks. Meanwhile, backlight signals are smoothed to ensure smooth transition between each region and its surrounding regions,which makes images downy on the vision.关键词
