AMLCD运动伪像仿真及优化
Motion blur simulation and optimization for AMLCD
摘要
Abstract
To pre-estimate the dynamic image quality of AMLCD (active matrix liquid crystal dis-play)efficiently and precisely,a multi-parameter simulation algorithm is proposed for the motion blur artifact of colorful natural images.Based on the time sequential analysis of the display system and the empirical formula of liquid crystal response curves,the light impulse of every sub pixel is in-tegrated within each frame along the eye trace using data from the video content.Thus,the subjec-tive perception of human eyes is simulated accurately under a variety of conditions.Using this algo-rithm,three current mainstream techniques for suppressing motion blur including faster response time,double refresh rate and blinking backlight are compared.Results show that among these three methods,blinking backlight provides the best result.However,it also brings ghost artifact unless the backlight synchronization is perfect and the duty cycle is selected carefully.According to the conclu-sions above,some cell phone manufacturer pre-estimated the performance of several AMLCDs under different conditions.It is found that the estimation fits well with the actual performance of the prod-ucts,which verifies the correctness and practicability of the algorithm.关键词
