Image forming apparatus, non-transitory computer-readable recording medium for storing image forming program, and image forming method

1. An image forming apparatus comprising:

an area setting unit configured to set a reading area on the basis of a page number;

a reading unit configured to read image data in the reading area of two consecutive pages;

a number recognizing unit configured to recognize a number from a result of reading the two consecutive pages by the reading unit;

a number determining unit configured to compare results of recognizing of the two consecutive pages by the number recognizing unit, determine a presence of consecutive numbers, and determine one of the consecutive numbers as the page number;

a number deleting unit configured to delete the page number from the image data determined by the number determining unit;

a number adding unit configured to add a new page number to the image data from which the page number has been added; and

a number blurring unit configured to perform a blurring process for shading the recognized number with a pattern if the number determining unit does not determine that there are consecutive numbers.

2. The image forming apparatus according to claim 1 , wherein the number determining unit determines the number on a first page of the two consecutive pages as the page number upon determining that there are consecutive numbers on the two consecutive pages.

3. The image forming apparatus according to claim 2 , wherein the number determining unit determines the number on a second page as the page number if there is no number subsequent to the number on the second page of the two consecutive pages where consecutive numbers are determined to be present.

4. A non-transitory computer-readable recording medium that stores an image forming program executed by a computer of an image forming apparatus, the image forming program comprising:

a first program code causing the computer to set a reading area on the basis of a page number;

a second program code causing the computer to read image data in the reading area of two consecutive pages;

a third program code causing the computer to recognize a number from a result of reading the two consecutive pages by the second program code;

a fourth program code causing the computer to compare results of recognizing of the two consecutive pages by the third program code, determine a presence of consecutive numbers, and determine one of the consecutive numbers as the page number;

a fifth program code causing the computer to delete the page number from the image data determined by the fourth program code;

a sixth program code causing the computer to add a new page number to the image data from which the page number has been deleted; and

a seventh program code causing the computer to perform a blurring process for shading the recognized number with a pattern if the fourth program code does not determine that there are not consecutive numbers.

5. The non-transitory computer-readable recording medium according to claim 4 , wherein the third program code causes the computer to determine the number on a first page of the two consecutive pages as the page number upon determining that there are consecutive numbers on the two consecutive pages.

6. The non-transitory computer-readable recording medium according to claim 5 , wherein the third program code causes the computer to determine the number on a second page as the page number if there is no number subsequent to the number on the second page of the two consecutive pages where consecutive numbers are determined to be present.

7. An image forming method comprising:

an area setting unit setting a reading area on the basis of a page number;

a reading unit reading image data in the reading area of two consecutive pages;

a number recognizing unit recognizing a number from a result of reading the two consecutive pages by the reading unit;

a number determining unit comparing results of recognizing of the two consecutive pages by the number recognizing unit, determining a presence of consecutive numbers, and determining one of the consecutive numbers as the page number;

a number deleting unit deleting the page number from the image data determined by the number determining unit;

a number adding unit adding a new page number to the image data from which the page number has been deleted;

a number blurring unit performing a blurring process for shading the recognized number with a pattern if the number determining unit does not determine that there are consecutive numbers.

8. The image forming method according to claim 7 , wherein the number determining unit determines the number on a first page of the two consecutive pages as the page number upon determining that there are consecutive numbers on the two consecutive pages.

9. The image forming method according to claim 8 , wherein the number determining unit determines a number on the second page as the page number if there is no number subsequent to the number on the second page of the two consecutive pages where consecutive numbers are determined to be present.

10. The image forming method according to claim 7 , wherein the consecutive numbers are Arabic numeral characters.

11. The image forming method according to claim 7 , wherein the consecutive numbers are characters selected from the group consisting of Chinese numeral characters and Roman numeral characters.
