Abstract
When there is a copy inhibiting dot pattern in an image, an image destruction processing unit performs image destruction processing to image data, and a storage processing unit stores in a storage unit the image data after the image destruction processing. An RGB/CMY conversion processing unit converts the image data into CMY image data C1, M1, Y1, and a UCR/black creation processing unit sets coefficient α of Formula “K1=min (C1, M1, Y1)×α” to “1,” and creates image data K1, C2, M2, Y2 by using Formula “C2=C1−K1, M2=M1−K1, Y2=Y1−K1.”
Claims7
An image processing apparatus which outputs document image data of a first color system configured from a predetermined plurality of colors to an image forming unit which forms images using developers of a plurality of colors of a predetermined second color system that is different from the first color system,
- the image processing apparatus comprising:
- a detection unit which detects whether there is a predetermined image forming inhibiting dot pattern in the document image data of the first color system;
- an image destruction processing unit which creates destruction data by converting pixel data of respective pixels configuring the document image data into a predetermined same value when the detection unit detects the image forming inhibiting dot pattern;
- a storage unit which stores the destruction data that has been created by the image destruction processing unit;
- a conversion processing unit which converts the destruction data stored in the storage unit into image data of the second color system;
- and
- a creation processing unit which creates image data including only a component of a specified color as one predetermined color among the respective colors of the developers from the image data converted to the second color system by the conversion processing unit.
An image processing method for an image processing apparatus for outputting document image data of a first color system configured from a predetermined plurality of colors to an image forming unit which forms images using developers of a plurality of colors of a predetermined second color system that is different from the first color system, the method comprising:
- a detection step of detecting whether there is a predetermined image forming inhibiting dot pattern in the document image data;
- an image destruction processing step of creating destruction data by converting pixel data of respective pixels configuring the document image data into a predetermined same value when the image forming inhibiting dot pattern is detected in the detection step;
- a storage step of storing the destruction data that has been created in the image destruction processing step;
- a conversion processing step of converting the destruction data stored in the storage step into image data of the second color system;
- and
- a creation processing step of creating image data including only a component of a specified color as one predetermined color among the respective colors of the developers from the image data converted to the second color system in the conversion processing step.
