摘要

為了消除液晶顯示器的殘影及抖動問題，過去已提出許多解決方式，但還是以提昇畫面更新率為一個最有效的方法，而如何擁有高品質插入的畫面，成了一個重大考驗。
在插入的圖像中，最害怕鋸齒邊和游離點去破壞畫面品質。而本篇論文提出了一個改善方案，使用漸層消去法來提昇畫面品質，漸層消去法是針對相關度低的區塊做一定程度的消去，而在消去的過程中，會有更多的漏洞導致圖像不完整，此時就必須運用取代法，修復破損的圖像，可說此二法是相輔相成，在使用漸層消去法之後，可明顯看到圖像有改善。再配合取代法及限定搜索範圍，可以達到消除鋸齒邊和游離點的成果。

To eliminate motion blur and jitter LCD problems in the past has made many methods. But to improve the frame rate is still one of the most effective way. How to insert images with high quality, has become a major problem.
In the interpolated image, have to avoid the point serrated edge and outlier to destroy image quality. And this paper proposed an improved scheme. Using a gradually elimination method to improve the image quality. The gradually elimination method can elimination some part of the block which has low Correlation. After we using the gradually elimination method, it can obviously improve the image quality. Also we use the replace image method and limited searching range. It’s good for Eliminating serrated edge and outlier.
