摘要： A character recognition device includes: an acquiring unit that acquires image data describing pixel values representing colors of pixels constituting an image; a binarizing unit that binarizes the pixel values; an extracting unit that extracts boundaries of colors in the image; a delimiting unit that delimits plural image areas in the image; a specifying unit that specifies, with regard to first image areas arranged according to a predetermined rule, pixels binarized by the binarizing unit, as a subject for character recognition, and specifies, with regard to second image areas not arranged according to the predetermined rule, pixels of areas surrounded by boundaries extracted by the extracting unit, as a subject for character recognition; and a character recognition unit that recognizes characters represented by the pixels specified by the specifying unit as a subject for character recognition.
