摘　　要：讨论了人眼在观看平板显示屏上运动图像时视觉失真的产生原因 ,并通过视觉感知实验对已有的视觉感知模型进行了修正 ,提出了将空间积分的影响加入到视觉感知模型中的改进方法 .本文还利用该模型对一些显示屏上运动图像的视觉感知过程进行了模拟 ,结果表明 ,采用本文提出的模型获得的运动图像的视觉感知效果图更加接近人眼实际所观测到的图像 .The cause of the motion artifacts, which is perceived on flat panel display when displaying sequence images with moving objects, is discussed in this paper. Based on perception experiment, the visual perception model of the human eye’s smooth pursuit movement was improved by including the influence of spatial integration. Simulation software has been developed to evaluate the perceived image quality on several display panels. The results indicate that the simulated images based on the proposed model are quite close to the actual perceived images. The proposed model may be useful for optimizing the driving method of display panels.
