Base Claim:
1. A user-interactive automatic translation device for a mobile device, comprising: a camera image controller for converting an image captured by a camera into a digital image; an image character recognition controller for user-interactively selecting a character string region to be translated from the digital image, performing a character recognition function on the selected character string region based on an optical character reader (OCR) function and character recognition information stored in a character recognition information database (DB) to generate a text string, and user-interactively correcting errors included in the text string; a text transmission controller for transmitting the error-corrected text string; and an automatic translation controller for receiving the error-corrected text string from the text transmission controller, performing a morpheme analysis, tagging, a structure analysis, a structure conversion, and a vocabulary conversion on the text string to generate a translation of the text string based on a grammar of a target language, wherein the morpheme analysis, the tagging, the structure analysis, the structure conversion, the vocabulary conversion, and the translation generation are performed based on information for translation stored in an automatic translation information DB; wherein the image character recognition controller includes: a region selection user interface unit for providing a user with an interface so that the user selects the character string region from the digital image, and receiving the character string region selected by the user; a character recognition unit for performing a character recognition function on the received character string region based on the OCR function and the character recognition information stored in the character recognition information DB; a text converting unit for converting the character-recognized character string into a standard text string; and a user interaction-based recognition error correcting unit for displaying the standard text string on a display window and to receive an error-corrected text string through the user interface, and wherein the user interaction-based recognition error correcting unit displays optimum word recognition candidates for the standard text string and recognition candidates for each optimum word recognition candidate such that the recognition candidates are displayed downward under the optimum word recognition candidates in the order from a high weight value to a low weight value, each recognition candidate being enclosed in a rectangle, and when one of the recognition candidates associated with an erroneous optimum word recognition candidate is selected through the user interface, the erroneous optimum word recognition candidate is replaced by the selected recognition candidate to correct the error of character recognition.

Claim 4:
4. The user-interactive automatic translation device for a mobile device of claim 1 , wherein the automatic translation controller includes: a sentence recognition pre-process for recognizing the text string sentence by sentence; a source language morpheme analyzing and tagging unit for analyzing source language morphemes of the sentence-by-sentence recognized text string based on first automatic translation information stored in the automatic translation information DB, performing tagging on the result and restoring each of vocabularies included in the text string into original form thereof to apply parts of speech to the recovered text string; a source language structure analyzing unit for analyzing a grammatical correlation and a modification structure of vocabularies included in each sentence of the recovered text string based on second automatic translation information stored in the automatic translation information DB; a source language/target language converting unit for performing a source language-to-target language conversion on the analyzed text string based on third automatic translation information stored in the automatic translation information DB to convert vocabularies of source language to vocabularies of target language; and a target language generating unit for applying a grammar of target language to the structure-converted and vocabulary-converted text string to generate a translation.
