Claim:
An image-processing device for extracting a recognition-target area including a character from a target image, the image processing device comprising: a display displaying the target image; a recognition-target-area-specifying unit allowing a user to specify an outline of the recognition-target area in the target image displayed on the display; a determination unit determining a plurality of colors existing on the outline of the recognition-target area specified by the recognition-target-area-specifying unit; a comparing unit comparing each of the plurality of colors determined by the determination unit with colors of pixels included in the recognition-target area; a color-conversion unit converting colors of the pixels included in the recognition-target area into a predetermined converted color when a result of the comparing unit finds that the difference between the colors of the pixels included in the recognition-target area and one of the plurality of colors existing on the outline of the recognition target area is within a predetermined range; and a character-recognition unit performing a character-recognition process on the recognition-target area in which the color of the pixels has been changed by the color-conversion unit.
