一种新型LCD运动模糊的测量分析系统

LCD motion blur measurement and analysis system

液晶显示器的运动模糊程度通常可以采用"运动图像响应时间(MPRT)"来表示,它已经被写入了VESA的平板显示器测量标准当中。本文建立了一种简单精确的运动模糊测量分析系统代替了复杂昂贵的追逐相机系统,该系统可以精确地测量液品亮度响应曲线(LCRC),并利用采集曲线根据人眼的平滑追踪和时域积分特性准确地仿真出所感知到的运动模糊图像。通过对阶跃LCRC进行一帧时间窗口卷积,直接计算MPRT。最后通过测量计算和视觉感知实验验证了仿真模型的准确性和系统的精确度。

＂Motion Picture Response Time （MPRT）＂ now is standardized in VESA FPDM to characterize the motion blur. In this paper a simple and precise LCD motion blur measurement and analysis system is built to replace the complex and expensive smooth pursuit camera system. It can measure LC response curve accurately. Based on the acquired curve, the perceived image can be simulated properly by smooth-pursuit eye tracking and temporal integration. MPRT can be calculated directly from the convolution of the step response curve with a temporal window function of 1-frame wide. Finally, measurement calculation and perception experiment verify the accuracy of the system and the simulation model.
