Generating an electronic document with reference to allocated font corresponding to character identifier from an image

1. An image processing apparatus comprising:

an image acceptance unit that accepts an image;

a character information adding unit that adds, via a processor, character information to the image accepted by the image acceptance unit, including: (i) a character code for uniquely identifying a character, (ii) a character position indicating a position of the character in the image, (iii) a character size indicating a size of the character, and (iv) a character color indicating a color of the character;

a font allocation unit that allocates font information without a drawing element as a font corresponding to the character code within the character information added by the character information adding unit; and

an electronic document generation unit that generates an electronic document for reference to the font information allocated by the font allocation unit, based on the character information added to the image by the character information adding unit, wherein

when text information of the character information of the electronic document is copied and pasted, the character code and the character color are acquired, and

the font information is added to the image as transparent characters that contain at least one of the font information, the character code and the character color.

2. The image processing apparatus as claimed in claim 1 ,

wherein

the electronic document generation unit generates the electronic document by adding the font information allocated by the font allocation unit to the image with the character information added by the character information adding unit.

3. The image processing apparatus as claimed in claim 1 ,

wherein

the image accepted by the image acceptance unit is a color image,

the apparatus further comprises a character color decision unit that decides the color of the character as the character information, based on the color of the character in the color image accepted by the image acceptance unit, and

the character information adding unit adds the character color decided by the character color decision unit as the character information.

4. An image processing apparatus comprising:

an image acceptance unit that accepts an image;

a character information adding unit that adds, via a processor, character information to the image accepted by the image acceptance unit, including: (i) a character code for uniquely identifying a character, (ii) a character position indicating a position of the character in the image, (iii) a character size indicating a size of the character, and (iv) a character color indicating a color of the character;

a font information storage that stores font information in which a font without drawing element is allocated to the character code; and

an electronic document generation unit that generates an electronic document for reference to the font information stored by the font information storage, based on the character information added to the image by the character information adding unit, wherein

when text information of the character information of the electronic document is copied and pasted, the character code and the character color are acquired, and

the font information is added to the image as transparent characters that contain at least one of the font information, the character code and the character color.

5. The image processing apparatus as claimed in claim 4 ,

wherein

the electronic document generation unit generates the electronic document by adding the font information stored by the font information storage to the image with the character information added by the character information adding unit.

6. A non-transitory computer readable medium storing a program causing a computer to execute a process for performing an image processing, the process comprising:

accepting an image;

adding character information to the accepted image, including: (i) a character code for uniquely identifying a character, (ii) a character position indicating a position of the character in the image, (iii) a character size indicating a size of the character, and (iv) a character color indicating a color of the character;

allocating font information without a drawing element as the font corresponding to the character code within the added character information; and

generating an electronic document for reference to the allocated font information, based on the character information added to the image, wherein

when text information of the character information of the electronic document is copied and pasted, the character code and the character color are acquired, and

the font information is added to the image as transparent characters that contain at least one of the font information, the character code and the character color.

7. A non-transitory computer readable medium storing a program causing a computer to execute a process for performing an image processing, the process comprising:

accepting an image;

adding character information to the accepted image, including: (i) a character code for uniquely identifying the character, (ii) a character position indicating a position of the character in the image, (iii) a character size indicating a size of the character, and (iv) a character color indicating a color of the character;

storing font information in which a font without drawing element is allocated to the character code; and

generating an electronic document for reference to the stored font information, based on the character information added to the image, wherein

when text information of the character information of the electronic document is copied and pasted, the character code and the character color are acquired, and

the font information is added to the image as transparent characters that contain at least one of the font information, the character code and the character color.
