Abstract: MFP matches low-resolution binary image data received by facsimile with a dot pattern showing a jaggy. If there is any matching region, the image data is converted into multivalued image data by performing jaggy correction in which the tone of a target dot in the region is substituted with a grayscale. MFP also generates a region identification attribute code based on the result of matching and the tone of the input image data. MFP enhances the respective resolutions of the image data after jaggy correction and the region identification attribute code. MFP then binarizes the image data having the enhanced resolution once again by a binarization method according to the region identification attribute code having the enhanced resolution.
