摘　　要：如何客观地评价和减小运动伪像是目前LCD科研人员急需解决的难题.根据人眼平滑追踪和亮度积分原理,基于实际采集的LCD亮度响应变化,采用模拟计算产生了运动模糊图像,并通过视觉感知实验,对仿真所得的模糊图像和实际观察到的运动模糊图像进行了实验,结果表明模拟产生的运动图像的模糊和人眼实际观看感觉到的模糊吻合得很好.How to evaluate and reduce the motion artifacts on LCD is a crucial issue for scientists. A new evaluation method is proposed based on the pixel transition curves measurement and algorithm of eye-trachag. The precise measurement system has been established to capture step luminance transition curves. Blurred image is simulated by means of luminance response and visual system. The new protocol which demonstrates both simulated and intrinsic blurring image on the same LCD is presented to do perception study. The results proved that the simulation method is high correlation with actual perceived motion blur.
