英文摘要：

Naxi pictograph is the only still using hieroglyph all over the world, which does a positive role in the research for evolution his- tory of human language. In the past, we process NaXi Pictograph by hand, that is very inefficient. Through the analysis for the characteristics and information processing of Naxi pictograph, the paper proposes a transcription scheme of the importing from Naxi phonetic into Latin Pinyin, and also optimizes this scheme. Based on Windows XP platform, the input method of Naxi pictograph is developed through adopting IMM- IME interface. After evaluation, the transformation accuracy of Naxi pinyin input method which is optimized is higher than that without optimization.
