In a case where a line noise suppression mode in which a line noise image is suppressed is enabled by a mode setting section 81, (A) a spatial filter process section 108 executes a spatial filter process with respect to a text pixel which have determined to be included in a text region by a segmentation process section 105, in which spatial filter process an edge enhancement degree of an image is smaller than that obtained when the line noise suppression mode is disabled, and (B) an output tone correction section 109 executes, with respect to the text pixel subjected to the spatial filter process, a tone correction process in which a contrast enhancement degree of an image is higher than that obtained when the line noise suppression mode is disabled.
