Information processing apparatus, information processing method, and computer program product for inserting information into in image data

1. An information processing apparatus that inserts corresponding information, which corresponds to character information contained in image data, to the image data in a form of an electronic file, the information processing apparatus comprising:

an image-data obtaining unit that obtains image data containing a plurality of pieces of character information;

a corresponding-information obtaining unit that obtains corresponding information that corresponds to the character information obtained from the image data;

an area-information obtaining unit that obtains area information that indicates an area to which the corresponding information is to be inserted, depending on a formation of lines containing the character information;

an insertion-style determining unit that determines an insertion style of the corresponding information based on the obtained area information; and

an information-insertion control unit that records, via a processor, the image data and the corresponding information on different layers in the electronic file and inserts the corresponding information into the image data in a visible color according to the insertion style determined by the insertion-style determining unit.

2. The information processing apparatus according to claim 1 , wherein the area-information obtaining unit obtains the area information based on the character information contained in the image data.

3. The information processing apparatus according to claim 1 , wherein the area-information obtaining unit obtains the area information depending on whether a predetermined character is found in the character information contained in the image data.

4. The information processing apparatus according to claim 1 , wherein the area-information obtaining unit obtains the area information depending on a result of checking whether predetermined character information is found in a first line on the image data corresponding to the corresponding information and a second line on the image data that lies immediately below the first line.

5. The information processing apparatus according to claim 1 , wherein the insertion-style determining unit sets a pale color as a color of texts of the corresponding information to be inserted.

6. The information processing apparatus according to claim 1 , wherein, when a predetermined character size is too large for the corresponding information to be included within the area obtained by the area-information obtaining unit, the insertion-style determining unit changes the color of texts from a specified color to a new color.

7. The information processing apparatus according to claim 6 , wherein the insertion-style determining unit sets a pale color as the new color.

8. An information processing method of inserting corresponding information, which corresponds to character information contained in image data, to the image data in a form of an electronic file, the information processing method comprising:

obtaining image data that contains a plurality of pieces of character information;

obtaining corresponding information that corresponds to the character information obtained from the image data;

obtaining area information that indicates an area to which the corresponding information is to be inserted, depending on a formation of lines containing the character information;

determining an insertion style of the corresponding information based on the obtained area information; and

recording, via a processor, the image data and the corresponding information on different layers in the electronic file and inserting the corresponding information into the image data in a visible color according to the determined insertion style.

9. A non-transitory computer-readable medium storing computer readable instructions thereon for inserting corresponding information, which corresponds to character information contained in image data, to the image data in a form of an electronic file, the instructions when executed by a computer causing the computer to perform a method comprising:

obtaining image data that contains a plurality of pieces of character information;

obtaining corresponding information that corresponds to the character information obtained from the image data;

obtaining area information that indicates an area to which the corresponding information is to be inserted, depending on a formation of lines containing the character information;

determining an insertion style of the corresponding information based on the obtained area information; and

recording the image data and the corresponding information on different layers in the electronic file and inserting the corresponding information into the image data in a visible color according to the determined insertion style.
