臺灣博碩士論文加值系統

電漿顯示器有尺寸大、視角廣、壽命長、厚度薄等優點，特別適合應用於高畫質電視及高解析度工作站螢幕等用途，但是在目前，電漿顯示器所顯示的畫面，仍然存在一些缺點，包括靜態畫面的迦碼值過高、亮度不連續，以及動態畫面的錯誤動態輪廓，這些影像瑕疵的消除對電漿顯示器能否成功的取代傳統電視有決定性的影響。本論文先介紹根據富士通架構所建立的電漿顯示器原始機，在顯示靜態影像時所面臨的影像瑕疵問題，並針對這些瑕疵所提出的解決方法。再介紹電漿顯示器在顯示動態畫面時會出現的影像瑕疵以及針對此瑕疵所提出的兩種解決方法，第一種方法的成本較低，容易實現，而第二種方法則較為精確。最後針對新的演算法對影像品質的提升做一整理，並討論未來可行的研究方向。

Plasma display panel (PDP) is praised for its large screen size, wide viewing angle, long life, and thinness, etc. It is a promising technology for applications such as high definition television (HDTV) or high-resolution computer workstation monitors. However, the pictures which the PDP displays still have some defects such as the excessive gamma value, the non-continuous gray scale brightness on static frames, and the dynamic false contour on dynamic frames. The elimination of these defects determinates whether the PDP will replace the CRT television. In this dissertation, the static image defects on the original PDP based on Fujitsu’s architecture are introduced and the solution is proposed first. Then the dynamic image defects are analyzed and two solutions are proposed. The first one not only costs lower but also applies more easily. The other one is complicated but accurate. Finally, the valid research prospects are discussed.
