Summary:Disclosed are an apparatus and a method for text recognition capability using a camera provided in a mobile communication terminal. Image pre-processing discriminates a text color and a text-background color in an input image, and unifies regions except the text into the text-background color, so that a text region and a background region surrounding the text region can be precisely separated. The image pre-processing method is adaptive to a photographing environment, whereby stable text recognition capability can be expected even if the photographing environment is variously changed.
