    Abstract: 數位攝影已成為人們記錄影像最便利的方法之一。當進行拍攝時,常常因為環境光的強度、光源角度及臉部本身的反光性,造成臉部區域出現過度曝光,產生亮點過大現象,而破壞了數位影像的美觀。本研究中,將針對數位相片臉部過度亮點的問題,以自動修補的方式提出有效的解決方法。本論文實驗中採用YCbCr色彩空間來界定膚色範圍,依據人臉特徵與人臉長寬比例做為偵測的篩選條件,找出人臉範圍後,針對人臉區域進行過度亮點偵測與修補。過度亮點偵測中會比較像素灰階值是否大於亮度閾值(Threshold),若大於亮度閾值則標示為目標亮點,最後在目標亮點周圍尋找可用來源資訊,進行點對點修補避免造成影像模糊,讓修補後的影像在人類視覺感官上看起來更自然與美觀。
