Application ID: 12710932

Base Claim:
1. An apparatus for improving text recognition capability in a mobile communication terminal with a camera, the apparatus comprising: a text region detection unit which determines if text exists in an input image, determines text color and text-background color surrounding the text when the text is determined to exist, and unifies a background region beyond a text region into the determined text-background color; an inversion-processing unit which determines if the text image with the unified background is inverted, and inversion-processes the text image when the text image is an inverted image; and a text recognition unit which recognizes the inverted text image or the text image with the unified background from the inversion-processing unit, and then outputs the result of recognition.

Claim 5:
5. The apparatus as claimed in claim 1 , wherein the text region detection unit acquires blobs having a same color with the text-background color, analyzes the blobs based on positions and sizes thereof, searches text-background blobs among the blobs, thereby determining the text-background region, and unifies the regions except the text-background region into the text-background color.
