Image processing device, image processing method, and storage medium storing program therefor

An image processing method comprising:

• reading a document and generating an image file representing an image of the read document;
• extracting a graphics area in the image represented by the image file;
• extracting a writing area in the image represented by the image file;
• extracting a character string present in the graphics area;
• extracting, from the writing area, text that includes the same character string as the character string extracted in a process of extracting the character string;
• and
• generating document data representing a document containing the graphics area and the text.

An image processing device comprising:

• a reading unit that reads a document;
• a graphics area extraction unit that extracts a graphics area from the document read by the reading unit;
• a writing area extraction unit that extracts a writing area from the document read by the reading unit;
• a character string extraction unit that extracts a character string presented in the graphics area;
• a text extraction unit that extracts from the writing area, text that includes the same character string as the character string extracted by the character string extraction unit;
• and
• a format association unit that associates information of the text with the graphics area.

A image processing device, comprising:

• a reading unit that reads a document;
• a graphics area extraction unit that extracts a graphics area from the document read by the reading unit;
• a writing area extraction unit that extracts a writing area from the document read by the reading unit;
• a character string extraction unit that extracts a character string presented in the graphics area;
• and
• an association unit that associates information of the writing area with the graphics area based on the character string extracted by the character string extraction unit.

A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function for image processing , the function comprising:
