Information processing device, program for operating the same, document scanning device, and document scanning system

A computer readable medium having computer readable instructions stored thereon, which, when executed by a computer, cause the computer to function as:

• an image data receiving unit which receives image data of each page of a double-sided document generated by a document scanning device by double-side scanning of the document;
• a recognizable direction adjustment information receiving unit which receives recognizable direction adjustment information outputted by the document scanning device as information to be used for adjusting a recognizable direction of the image data of a back page of the document to a standard recognizable direction which is defined as the recognizable direction of the image data of a front page of the document;
• and
• a vertical inversion unit which vertically inverts the image data of the back page as needed based on the recognizable direction adjustment information so that the recognizable direction of the image data of the back page will be in the standard recognizable direction.

A document scanning device comprising:

• a scanning unit which scans each page of a double-sided document and thereby generates image data of each page;
• an image data outputting unit which outputs the image data of each page generated by the scanning unit;
• and
• a recognizable direction adjustment information outputting unit which outputs recognizable direction adjustment information as information to be used for adjusting a recognizable direction of the image data of a back page of the document to a standard recognizable direction which is defined as the recognizable direction of the image data of a front page of the document.

A document scanning system comprising a document scanning device and an information processing device, wherein:

• the document scanning device includes:
• a scanning unit which scans each page of a double-sided document and thereby generates image data of each page;
