Image scanning device and image processing apparatus including card scanning function, and image scanning method thereof

An image scanning method comprising:

• image scanning in which a plurality of documents placed on a platen are scanned at a single time and a plurality of pieces of image data are generated;
• and
• image data processing in which the plurality of pieces of image data are processed,
• wherein, in the image scanning, when the first surfaces of the plurality of documents are scanned at a single time, each of the plurality of documents being placed in one of a plurality of predetermined areas on the platen, and thereafter the second surfaces opposite to the first surfaces of the plurality of documents are scanned at a single time, each of the plurality of documents being turned over and placed again in the one of the plurality of predetermined areas, in the image data processing, one of the image data generated by scanning the first surfaces of the plurality of documents is associated with a corresponding one of the image data generated by scanning the second surfaces of the plurality of documents for each of the plurality of predetermined areas, as pieces of image data of a front surface and a back surface.

A non-transitory computer-readable medium storing a program causing a processor of an image scanning device to execute a process, the process comprising:

• image scanning in which a plurality of documents placed on a platen are scanned at a single time and a plurality of pieces of image data are generated;
• and
• image data processing in which the plurality of pieces of image data are processed,
• wherein, in the image scanning, when the first surfaces of the plurality of documents are scanned at a single time, each of the plurality of documents being placed in one of a plurality of predetermined areas on the platen, and thereafter the second surfaces opposite to the first surfaces of the plurality of documents are scanned at a single time, each of the plurality of documents being turned over and placed again in the one of the plurality of predetermined areas, in the image data processing, one of the image data generated by scanning the first surfaces of the plurality of documents is associated with a corresponding one of the image data generated by scanning the second surfaces of the plurality of documents for each of the plurality of predetermined areas, as pieces of image data of a front surface and a back surface.
