1. A character recognition device comprising: an acquiring device that acquires image data describing pixel values representing colors of pixels constituting an image; a binarizing device that binarizes the pixel values described in the image data acquired by the acquiring device; an extracting device that extracts boundaries of colors in the image represented by the image data acquired by the acquiring device; a delimiting device that carries out a labeling processing on the image represented by the image data acquired by the acquiring device to delimit a plurality of image areas in the image; a specifying device that specifies, with regard to first image areas arranged according to a predetermined rule among the plurality of image areas delimited by the delimiting device, pixels binarized by the binarizing device, corresponding to the first image areas, as a subject for character recognition, and specifies, with regard to second image areas not arranged according to the predetermined rule among the plurality of image areas delimited by the delimiting device, pixels of areas surrounded by boundaries extracted by the extracting device, corresponding to the second image areas, as a subject for character recognition; and a character pixel recognition device that recognizes characters represented by the pixels specified by the specifying device as a subject for character recognition, wherein the predetermined rule is an arrangement of the plurality of image areas.
