Abstract

An image processing device includes an input device and circuitry. The input device inputs data. The circuitry converts text information to be printed included in the data to generate converted information and outputs data for image formation including the converted information.

First claim

The invention claimed is:

1. An image processing device comprising:
an inputter to input data; and
circuitry configured to:
search and extract text information to be printed from the input data according to an extraction condition;
convert the text information to be printed into raster image data; and
convert a part of an image of text of the raster image data into invisible information to generate converted information; and
output data for image formation including the converted information,
wherein the invisible information is information detectable by an infrared sensing device.

2. The image processing device according to claim 1 ,
wherein the converted information includes invisible information corresponding to the text information.

3. The image processing device according to claim 1 ,
wherein the circuitry is configured to:
convert a part of an image of text of the text information into invisible information to generate the converted information; and
add the converted information to an area from which the text information is deleted in the data.

4. The image processing device according to claim 3 ,
wherein the circuitry is configured to convert an edge portion of the text into invisible information to generate the converted information.

5. The image processing device according to claim 3 ,
wherein the circuitry is configured to convert a part of an entire image area of the text into invisible information to generate the converted information.

6. The image processing device according to claim 5 ,
wherein the circuitry is configured to convert partially an inside area of an edge portion of the text to include micro texts at given intervals as invisible information.

7. The image processing device according to claim 1 ,
wherein the circuitry is configured to:
convert the text information to be printed into one of a one-dimensional code image and a two-dimensional code image;
acquire a background image; and
set the code image as invisible information to the background image that is visible information acquired, to generate the converted information.

8. The image processing device according to claim 7 ,
wherein the circuitry is configured to acquire the background image from the data.

9. The image processing device according to claim 1 ,
wherein the circuitry is configured to extract, as the text information to be printed, text information in an area corresponding to area information set as an extraction condition, from the data.

10. The image processing device according to claim 1 ,
wherein the circuitry is configured to extract, as the text information to be printed, text information corresponding to color information set as an extraction condition, from the data.

11. The image processing device according to claim 1 ,
wherein the data is print data output by a printer driver.

12. The image processing device according to claim 1 ,
wherein the data is one of portable document format (PDF) data and Extensible Markup Language (XML) Paper Specification (XPS) data.

13. The image processing device according to claim 1 ,
wherein the converted information includes invisible information corresponding to the text information, and
wherein the converted information indicates visible information of the text information together with the invisible information under visible light and indicates the invisible information under invisible light.

14. The image processing device according to claim 1 ,
wherein the converted information includes invisible information corresponding to the text information, and
wherein the invisible information is concealed by a background image and a combination of printing amounts of colorants.

15. An image processing system comprising:
an information processor including:
circuitry configured to receive an extraction condition set on a screen displaying a print preview of data; and
an outputter to output the data and the extraction condition received; and

an image processor to give an image forming instruction in response to a print instruction from the information processor,
the image processor including:
an inputter to input the data and the extraction condition; and
circuitry configured to:
search and extract text information to be printed from the data according to the extraction condition;
convert the text information to be printed into raster image data; and
convert a part of an image of text of the raster image data into invisible information to generate converted information;
and
output data for image formation including the converted information,

wherein the invisible information is information detectable by an infrared sensing device.

16. The image processing system according to claim 15 ,
wherein the circuitry of the information processor is configured to receive setting of one of area information and color information as the extraction condition.

17. A method comprising:
inputting data;
searching and extracting text information to be printed from the data according to the extraction condition;
converting the text information to be printed into raster image data; and
converting a part of an image of text of the raster image data into invisible information to generate converted information;
and
outputting data for image formation including the converted information,
wherein the invisible information is information detectable by an infrared sensing device.
