本論文提出一個新的演算法來解決高動態範圍影像在液晶螢幕上的顯示問題，所提出的演算法結合螢幕校正和新的色調映射運算子。螢幕校正可以讓影像在任何一台螢幕上呈現正確的色彩。所提出的色調重現運算子結合攝影色調映射函數和兩個基於區域對比影像和平滑影像所估算出的參數。高動態範圍影像經由本論文所提出的演算法處理後在亮度、對比度、色彩準確性、能見度都有良好的表現，並且沒有對影像造成任何人工現象。

This paper presents a new algorithm to solve the high dynamic range image display problem in LCD monitor. The proposed algorithm combines the LCD calibration and the new tone mapping operator. The LCD calibration can let image is accurate in color on every monitor. The new tone mapping operator combines the photographic tone mapping function and two new additional items which are based on the local contrast map and the smoothed map. The images processed through the proposed algorithm have better brightness, contrast, color accuracy, and visibility without producing undesired artifacts.
