A method for providing a correct e-dictionary search result for a document recognition result includes performing character recognition of a document in which Korean characters (Hangul) and Chinese characters are mixed and displaying a recognition result. If a character string to be searched is selected by a user from the recognition result, determining whether the selected character string corresponds to Hangul or Chinese characters, detecting a Hangul word or a Chinese word included in the selected character string, and outputting an e-dictionary search result corresponding to the detected Hangul or a Chinese word. Accordingly, the user can use an e-dictionary function without directly inputting a search word and obtain a correct e-dictionary search result for a document in which Hangul and Chinese characters are mixed.
