dc.description.abstract  電泳式顯示器(EPD)擁有雙穩態、寬視角等特性,容易在任何光源下閱讀,因此非常適合應用於電子閱讀器(E-Readers)的顯示螢幕。目前電泳式顯示器顯示靜止圖像的方法已經有很好的研究結果,但是如何在電泳式顯示器播放視訊影像還是一個很大的挑戰,這是因為電泳式顯示器的反應速度比液晶顯示器低很多,至今,還沒有任何電子閱讀器可以流暢播放視訊影像。   本論文設計一套影像處理軟體,用於最佳化EPD播放視訊影像,分析在連續frames之每個像素的變化,根據連續frames之間的每個像素之停滯時間的時間參數進行補償,最後再將影像驅動的資訊及記錄著驅動正負電壓的持續時間的資訊送入EPD系統內,該軟體可自動最佳化指定播放速率下的播放效果。此外我們設計了擾動波形,改善驅動視訊影像時所產生的擴散問題,並使用影像處理技術,使電泳式顯示器可播放較複雜的灰階影像。zh_TW
dc.description.abstractThe electrophoretic display (EPD) has been popularly applied on electronic readers (E-Readers), but its response time is still a bottleneck such that none of commercial E-Readers can play videos on the EPD smoothly. In this paper, the detailed issues regarding the response time of the EPD are well addressed. An image processing tool based on the measured response speed under different image retention time has been proposed. Although the response time of the EPD is still lower than liquid crystal displays, the tool can automatically optimize the video quality under the specified data frame rate. In addition, we also design alternative approach which solves the problem of pixel diffusion by giving a pre-shaking the all unchanged pixel.en_US
