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

1. An image-processing 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; and

a production unit that produces image data representing an overall image that includes: the document image represented by the image data that is acquired by the acquisition unit, a differentiation image that is positioned within the document image and that allows a 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 representing information for acquiring the document image in a state in which the differentiation image is not positioned.

2. The image-processing device of claim 1 , wherein the information image includes an image that represents information specifying a process for erasing the differentiation image that positioned within the document image.

3. The image-processing device of claim 1 , wherein the information image includes an image that represents a storage location where image data representing the document image in a state in which the differentiation image is not positioned is stored.

4. 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 a 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.

5. The image-processing device of claim 4 , wherein:

the information image includes an image that represents information specifying a process for erasing the differentiation image that has been positioned within the document image; and

the first acquisition unit includes:

a specification unit that, based on information represented by the information image included in the overall image represented by the image data that has been acquired, specifies the details of the process for erasing the differentiation image from the overall image, and

a production unit that implements the process for which the details have been specified by the specification unit and produces image data that represents an image in which the differentiation image has been erased from the overall image.

6. The image-processing device of claim 4 , wherein:

the information image includes an image that represents a storage location where image data representing the document image in a state in which the differentiation image is not positioned is stored, and

the second acquisition unit acquires, from the storage location represented by the information image included in the overall image represented by the acquired image data, the image data that is stored in the storage location.

7. 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 a 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.

8. An image-forming 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 a user to differentiate an image of red characters residing in a predetermined range from an image of characters in colors that do not reside within 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;

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; and

an image formation unit that forms an image corresponding to the image data acquired by the second acquisition unit in recording media.

9. 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 a 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.

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

acquiring image data that represents an overall image that includes: a document image that includes characters, a differentiation image that is positioned within the document image and that allows a user to differentiate an image of red characters residing in the range from an image 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; and

acquiring image data that represents the document image in a state in which the differentiation image is not positioned based on the information represented by the information included in the overall image represented by the acquired image data.
