7. A method for improving text recognition capability in a mobile communication terminal with a camera, the method comprising the steps of: determining if text exists in an input image; determining text color and text-background color surrounding the text when the text is determined to exist; unifying background regions beyond a text region into the determined text-background color; and recognizing an inverted text image or text image with the unified background regions from an inversion-processing unit, and then outputting the result of recognition.

The method as claimed in claim 7 , further comprising: acquiring blobs having a same color with the text-background color; analyzing the blobs based on positions and sizes thereof, and then searching text-background blobs among the blobs; and determining the text-background region through the search of the text-background blobs, and unifying the regions except the text-background region into the text-background color.
