    Abstract: An apparatus and method for recognizing a character based on a photographed image. The apparatus includes an image determining unit, an image effect unit, a binarizing unit and a character recognizing unit. The image determining unit is configured to select, from an input image, a Region Of Interest (ROI) to be used for image analysis when the input image is input, and to analyze the selected ROI to determine a type of the input image. The image effect unit is configured to apply to the input image, an image effect for distinguishing a character region and a background region in a display screen if the type of the input image indicates that the input image is obtained by photographing a display screen. The binarizing unit is configured to binarize the input image or the output of the image effect unit according to the determined type of the input image. The character recognizing unit is configured to recognize a character from the binarized input image.
