  6. A simulation method is proposed to predict the motion artifacts of plasma display panels ( pdps ). the method simulates the behavior of the human vision system when perceiving moving objects. the simulation is based on the measured temporal light properties of the display for each gray level and each phosphor. both the effect of subfield arrangement and phosphor decay are involved. a novel algorithm is proposed to improve the calculation speed. the simulation model manages to predict the appearance of the motion image perceived by a human with a still image. the results are validated by a set of perceptual evaluation experiments. this rapid and accurate prediction of motion artifacts enables objective characterization of the pdp performance in this aspect

    針對目前等離子顯示屏普遍存在的運動偽像問題，提出了一種新穎的模擬計算方法，該方法實現了對等離子體顯示屏運動偽像的準確、快速估計.該方法通過測量等離子顯示屏不同顏色不同灰度下光信號隨時間的變化情況，模擬人眼對運動圖像的視覺感知行為，模擬計算出任意圖像以一定速度運動下的視覺感知效果.新演算法不但加入了等離子顯示屏熒光粉的延遲效應的影響，而且提高了模擬計算速度.所得模擬結果與實際主觀視覺感知實驗相符.這種快速準確的估計使對等離子顯示器件運動偽像的客觀評價成為可能
