摘要： Disclosed is a method and an apparatus for recognizing characters using an image. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

摘要： A method for setting a lip region of a face included in an image, including setting a first region and a second region in an image including a face, identifying contrast information of the first region, setting a threshold for binarization using the contrast information, and binarizing the second region based on the threshold. A region in which a pixel having an identical binary value continuously distributed within a predetermined number of ranges in the binarized image is set as an eye candidate object. An eye region is then extracted from the eye candidate object based on geometric characteristic of an eye region in an image, and the lip region is set with reference to the extracted eye region based on geometric information of the eye region and the lip region.
