    • An image processing apparatus includes an object type determining unit that determines whether a drawing object in the input image data includes a color character group; a background area extracting unit that extracts the background area on which the color character group is formed in the drawing object; a monochromatic conversion unit that, when the drawing object is determined to include the color character group, generates monochromatic image data by performing monochromatic conversion of the input image data with minimum luminance of a main color; a pattern generating unit that, when the drawing object is determined to include the color character group, generates, according to the hue of the color character group, pattern image data to be added to the background area of the post-monochromatic-conversion color character group; and a synthesizing unit that synthesizes the monochromatic image data and the pattern image data.

    • An image processing apparatus is capable of performing a plurality of toner-saving processes each reducing an amount of toner consumed to form an image. The apparatus includes a selecting unit that allows a user to select one toner saving process from the plurality of toner saving processes; a toner saving unit that performs the one toner saving process selected through the selecting unit; and a display unit that provides, when the one toner saving process is a predetermined toner saving process that yields a printed output whose print quality is not easily presumed by the user, a preview display representing the print quality of the printed output to be yielded by the one toner saving process.
