液晶显示器运动模糊测量方法及研究进展

运动模糊是影响显示图像质量的关键问题之一,对液晶显示器(LCD)运动模糊进行了详细的综述.首先概述了运动模糊的成因及改善方案,然后介绍了两类运动模糊测量方法:直接测量法、间接模拟法.直接测量法包括人眼主观评价法、高速相机法、追踪相机法、旋转镜面法、亮度计测量法等;间接模拟法利用灰阶亮度响应时间、模糊图像等基础数据进行仿真,选取不同的数学模型模拟人眼的平滑追踪、亮度时域积分.详细分析了各种检测方法的特点,最后进行归纳总结.

Motion blur measurement method and research progress of liquid crystal display

Motion blur is one of the key problems that affect the quality of display images.In this paper,motion blur of liquid crystal display (LCD) is reviewed in detail.First,the causes of motion blur and improvement scheme are introduced.Then,two kinds of motion blur measurement methods are introduced:direct measurement method and indirect simulation method.Direct measurement method including the subjective evaluation of the human eye,high-speed camera method,tracking camera method,rotating mirror method,brightness meter measurement method;indirect simulation method using gray-scale brightness response time,fuzzy image and other basic data simulation the human eye's smooth tracking and brightness time domain integration.The characteristics of various measurement methods are analyzed in detail,and the conclusion is summarized.
