摘要
开发了一种彩色交流等离子体显示器(ACPDP)任意运动速度动态假轮廓仿真的“时间分割法”,将以一定速度运动的图像按照时间的顺序拆分成多幅图像,根据原始图像得到全部拆分图像的灰度分布矩阵,利用人眼的积分效应公式得到感知的视觉图像矩阵,并通过彩色ACPDP的放电原理对其简化最终得到与子场权值分布相对应的动态假轮廓仿真计算公式.利用时间分割法对不同运动速度图像运动的仿真结果表明,“时间分割法”再现了动态假轮廓现象产生的机理和过程,找到了子场编码与动态假轮廓产生之间的重要关系,为评价运动图像的质量、提高彩色ACPDP的运动图像显示质量提供了理论依据.
A time-split method for simulating dynamic false contours （DFC） of motion images with random speed in color alternate-current plasma display panel （ACPDP） is developed. Splitting motion image with the certain speed according to the order of time into many pictures, Receiving the grey level distribute matrix that the all divided up pictures according to the primitive picture, and then the picture matrix of the vision is received according to integral characteristics of human eyes. And the dynamic false contours simulation calculation formula corresponding to sub field weight distribution is received finally by working mechanism of ACPDP. The simulation result shows that by simulation of motion images with random speed using the time-split method, finding the mechanism of DFC and the important relation between the sub-field code and DFC. And the simulation results provide a theoretical base for evaluating and promoting the display quality of motion images in ACPDP.
