Abstract
An image processing apparatus includes: a printing unit that prints image information containing two or more colors with a plurality of color information corresponding to a plurality of specified colors; and a changing unit that changes, when a total toner amount is larger than a threshold value, at least one of the plurality of color information corresponding to one of the plurality of specified colors so that the total toner amount to be used for printing the image information is smaller than the threshold value.
Claims13
An image processing apparatus comprising:
- a converting unit that converts image information having no less than three color information into image information having two color information;
- a printing unit that prints the converted image information having the two color information;
- a changing unit that, when a total toner amount is larger than a threshold value, changes one of the two color information of the converted image information so that the total toner amount to be used for printing the converted image information is smaller than the threshold value;
- and
- a method selecting unit that selects a method of changing the one of the two color information by the changing unit,
- wherein the method selecting unit selects the method of changing the one of the two color information according to an attribute of the image information, and the method selecting unit changes the one of the two color information with preserving hue for an area in which the attribute of the image information is graphics or an image.

An image processing apparatus comprising:
- a color converting unit that converts image information having no less than three color information into image information having two color information;
- a calculating unit that calculates a total toner amount used for printing the image information according to the two color information obtained through the conversion of the color converting unit;
- a determining unit that determines whether the total toner amount calculated by the calculating unit exceeds a threshold value, or not;
- a printing unit that prints the converted image information having the two color information;
- a changing unit that, when a total toner amount is larger than the threshold value, changes one of the two color information of the converted image information so that the total toner amount to be used for printing the converted image information so that the total toner amount is smaller than the threshold value;
- and
- a method selecting unit that selects a method of changing the one of the two color information by the changing unit,
- wherein the method selecting unit selects the method of changing the one of the two color information according to an attribute of the image information, and the method selecting unit changes the one of the two color information with preserving hue for an area in which the attribute of the image information is graphics or an image.

An image forming apparatus comprising:
- a color converting unit that converts image information having no less than three color information into image information having two color information;
- an image forming unit that includes four or more developing units, and forms an image with the developing units;
- a calculating unit that calculates a total toner amount used by the developing units of the image forming unit according to the two color information obtained through the conversion of the color converting unit;
- a determining unit that determines whether the total toner amount calculated by the calculating unit exceeds a threshold value, or not;
- a printing unit that prints the converted image information having the two color information;
- a changing unit that, when a total toner amount is larger than the threshold value, changes one of the two color information of the converted image information so that the total toner amount to be used for printing the converted image information is smaller than the threshold value;
- and
- a method selecting unit that selects a method of changing the one of the two color information by the changing unit,
- wherein the method selecting unit selects the method of changing the one of the two color information according to an attribute of the image information, and the method selecting unit changes the one of the two color information with preserving hue for an area in which the attribute of the image information is graphics or an image.
