APPARATUS AND METHOD FOR RECOGNIZING CHARACTERS USING A CAMERA
First Claim
1. A method for recognizing characters of an image captured using a camera in a mobile terminal, comprising:
- capturing, by the camera, an image of a signboard;
extracting a text area from the captured image of the signboard;
recognizing characters from the extracted text area;
generating similar characters of up to a predetermined priority level for each of the recognized characters of the extracted text area;
acquiring location information of an area within a predetermined range from a current position of the mobile terminal;
extracting at least one store name from the location information;
generating at least one text by combining the similar characters according to weights;
comparing the at least one text with the extracted at least one store name; and
outputting a comparison result.
