Image-processing device, image-forming device, and storing medium

An image-processing device comprising:

• a first acquisition unit that acquires image data representing an overall image that includes:
• a document image that includes characters, a differentiation image that is positioned within the document image and that allows the user to differentiate an image of red characters residing in a predetermined range from an image of characters of colors that do not reside in that range, and an information image that represents information for acquiring the document image in a state in which the differentiation image is not positioned;
• and
• a second acquisition unit that, based on information represented by the information image included in the overall image represented by the image data, acquires image data that represents the document image in a state in which the differentiation image is not positioned.

An image-forming device comprising:

• a memory that stores a red range occurring within a color space;
• an acquisition unit that acquires image data representing a document image that includes characters;
• a production unit that produces image data representing an overall image that includes:
• a document image represented by the image data acquired by the acquisition unit,
• a differentiation image that is positioned within the document image and that allows the user to differentiate an image of red characters residing in the range from an image formed in colors other than red, and
• an information image that represents information for acquiring the document image in a state in which the differentiation image is not positioned;
• and
• an image formation unit that forms an image corresponding to the image data produced by the production unit in recording media.

A computer-readable storing medium storing a computer program that causes a computer to execute:

• storing a red range occurring within a color space;
• acquiring image data that represents a document image that includes characters;
• and
• producing image data that represents an overall image that includes:
• a document image represented by the acquired image data,
• a differentiation image that is positioned within the document image and that allows the user to differentiate an image of red characters residing in the range from an image formed of colors other than red, and
• an information image that represents information for acquiring the document image in a state in which the differentiation image is not positioned.
