本文探讨了LCD运动图像模糊的原理。具体分析了sinc模型和sin^2模型的LCD运动图像模糊的原理，同时由于前两种模型实现复杂的特点，提出了一种具有空间域处理简单的双sinc模型来描述LCD运动图像的模糊效应，仿真结果显示：双sinc的运动图像的模糊模型在空间域和频率域中的处理与现实的运动模糊效应相一致。

英文摘要：

In this paper, we discuss the theory of LCD motion blur. Based on home and aboard research profit, the sinc model and sin^2 model are analyzed detailedly. However, the two model are too complex for hardware implement;so we present a simplified double sinc model which can be processed in both the space domain and frequency domain. The simulation results show that the double sinc motion blur model consist with the real blur effect in both space domain processing and frequency domain processing.
