摘　　要：LCD显示器上显示运动图像时除了边缘模糊之外,还会在物体边缘发生色彩畸变。本文首先分析了彩色畸变的原因,提出了一种通过分别测量三基色时间阶跃响应曲线来刻画运动图像色变的方法,利用对响应曲线在一帧宽度时间的积分结果计算出仿真图像,提出了几种评价并量化运动图像色变的参数,并通过视觉感知实验分析了相关性。Apart from motion edge blur, another motion artifact present in LCDs is the occurrence of wrongly colored edges for moving object, also referred to as motion-induced chromatic aberration. The causes of chromatic aberrance are analysed and a method to characterize motion color artifacts from tempo- ral step response measurements of the Primary colors is proposed. Some parameters of chromatic aberrance are proposed and the correlations are analyzed with a perception exoeriment.
