Image reading apparatus and program reading a first surface and a second surface of a sheet and detecting a first image at a first edge and a second image at a second edge of a sheet if a double feed of a sheet is detected in order to combine first image data and second image data of the first and second images if a double feed is detected

An image reading apparatus, comprising:

• a reading unit configured to read images on first and second sides of a sheet and generate separate image data for both the first and second sides of the sheet;
• a detection unit configured to detect a double feed of the sheet;
• and
• a controller configured to:
• determine whether the double feed of the sheet has been detected based on output from the detection unit;
• determine, based on the generated image data, whether at least part of each of the read images is at a respective edge of each of the first and second sides of the sheet only if the double feed of the sheet has been detected;
• if the double feed of the sheet has been detected, combine the image data to generate combined image data corresponding to the read images for both first and second sides of the sheet when it is determined that at least part of each of the read images at the respective edge of each of the first and second sides of the sheet;
• and
• process the combined image data such that a combined image corresponding to combined image data has a predetermined size.

A non-transitory computer-readable medium storing a program therein, which when executed, causes a computer to perform a process comprising:

• reading a first image on a first surface of a sheet and a second image on a second surface of the sheet and generating first and second image data from the first and second surfaces, respectively;
• detecting a double feed of the sheet;
• determining, based on the first and second image data, whether the first image is at a first edge of the first surface and the second image is at a second edge of the second surface of the sheet only if the double feed of the sheet has been detected;
• if the double fee of the sheet has been detected, combining the first and second image data into combined image data corresponding to the first and second images when both the first image is at the first edge and the second image is at the second edge;
• and
• processing the combined image data such that a combined image corresponding to the combined image data has a predetermined size.
