Abstract
An image forming apparatus with a saving mode in which imaging materials to be used are reduced, includes: an image processing part that converts image data from which an image will be formed into corresponding image data in an output color space; and an image forming part that forms the image from the image data converted by the image processing part, using the imaging materials, the image processing part reducing a color component of non-dominant (n+m)-component color mixed into a dominant n-component color in the image data converted, where n and m are integers of 1 or greater.
Claims15
An image forming apparatus with a saving mode in which imaging materials to be used are reduced, comprising:
- an image processing part that converts image data from which an image will be formed into corresponding image data in an output color space;
- and
- an image forming part that foams the image from the image data converted by the image processing part, using the imaging materials;
- wherein
- the image processing part reduces a color component of non-dominant (n+m)-component color mixed into a dominant n-component color in the image data converted, where n and m are integers of 1 or greater;
- and
- the image processing part converts a process black component produced by the substantially equal amounts of YMC color components among all the YMC color components approaching to the substantially equal amounts to a K color component.
An image forming apparatus comprising:
- a recognition part that recognizes that a saving mode is set to reduce imaging materials to be used;
- an image processing part that converts a color which is produced by colorants of N colors in image data, from which an image will be formed, into a color which is produced by colorants of from one color to (N-1) colors when the color recognition part recognizes that the saving mode is set, where N is an integer of 2 or greater;
- and
- an image forming part that forms an image from the image data converted by the image processing part;
- wherein
- the image processing part converts a process black component produced by the substantially equal amounts of YMC color components among all the YMC color components approaching to the substantially equal amounts to a K color component.
An image processing method that makes a reduction in imaging materials to be used in a saving mode, comprising:
- inputting image data,
- reducing a color component of a non-dominant (n+m)-component color mixed with a dominant n-component color in the image data in conjunction with or after the conversion into corresponding image data in an output color space, where n and m are integers of 1 or greater;
- outputting the image data in the output color space in which the color component of the non-dominant (n+m)-component color has been reduced;
- and
- converting a process black component produced by substantially equal amounts of YMC color components to a K color component for the image data in which the chroma has been reduced in conjunction with or after the conversion to the output color space.
An image processing method that performs a reduction in imaging materials in a saving mode, comprising:
- reducing chroma of pixels positioned at a predetermined area around a gray axis in image data, before converting the image data from which an image will be formed into corresponding image data in an output color space;
- converting a process black component, produced by substantially equal amounts of YMC color components among all the YMC color components approaching to the substantially equal amounts by reducing the chroma values, to a K color component in conjunction with the color conversion to the output color space;
- and
- making output correction on YMCK image data after the color conversion to the image data in the output color space.
