Abstract
An image forming apparatus includes an image reading that reads an original document. An image processing unit determines a region other than a first document region corresponding to the first surface of the original document. The region other than the first document region is eliminated from first image data. A region other than a second document region corresponding to the second surface of the original document is determined. The region other than the second document region from the second image data is eliminated. A printing image is generated. An image forming unit prints the printing image generated by the image processing unit on a single surface of a recording medium.
Claims18
An image forming apparatus comprising:
- a scanner configured to generate image data by reading a region including a first surface of an original document and a region including a second surface of the original document, respectively, in a state in which regions other than the first and second surfaces of the document are respectively read with low luminance;
- a processor configured to:
- determine, from a first image data which was generated by the scanner reading a first surface of the original document, a region other than a first document region corresponding to the first surface of the original document using a difference in luminance in the first image data, wherein a region with low luminance in the first image data is determined to be the region other than the first document region,
- eliminate the region other than the first document region from the first image data,
- determine, from a second image data which was generated by the scanner reading a second surface of the original document, a region other than a second document region corresponding to the second surface of the original document using a difference in luminance in the second image data, wherein a region with low luminance in the second image data is determined to be the region other than the second document region,
- eliminate the region other than the second document region from the second image data, and
- generate, for printing on a single surface of a recording medium, a printing image including:
- the first read image with the region other than the first document region eliminated, and the second read image with the region other than the second document region eliminated;
- and
- a printer configured to print the generated printing image on a single surface of a recording medium.

An image forming method comprising the steps of:
- generating a first image data by reading a region including a first surface of an original document in a state in which a region other than the first surface of the document is read with low luminance;
- determining, from the first image data, a region other than a first document region corresponding to the first surface of the original document using a difference in luminance in the first image data, wherein a region with low luminance in the first image data is determined to be the region other than the first document region,
- eliminating, from the first image data the region other than the first document region corresponding to the first surface of the original document;
- generating a second image data by reading a region including a second surface of the original document in a state in which a region other than the second surface of the document is read with low luminance;
- determining, from the second image data, a region other than a second document region corresponding to the second surface of the original document using a difference in luminance in the second image data, wherein a region with low luminance in the second image data is determined to be the region other than the second document region,
- eliminating, from the second image data a region other than a second document region corresponding to the second surface of the original document;
- generating, for printing on a single surface of a recording medium, a printing image including:
- the first read image with the region other than the first document region eliminated, and the second read image with the region other than the second document region eliminated;
- and
- printing the generated printing image on a single surface of a recording medium.

A non-transitory recording medium in which a program for image forming which may be executed by a processor is stored, the program causing the processor to execute:
- generating a first image data by reading a region including a first surface of an original document in a state in which a region other than the first surface of the document is read with low luminance;
- determining, from the first image data, a region other than a first document region corresponding to the first surface of the original document using a difference in luminance in the first image data, wherein a region with low luminance in the first image data is determined to be the region other than the first document region,
- eliminating, from the first image data the region other than the first document region corresponding to the first surface of the original document;
- generating a second image data by reading a region including a second surface of the original document in a state in which a region other than the second surface of the document is read with low luminance;
- determining, from the second image data, a region other than a second document region corresponding to the second surface of the original document using a difference in luminance in the second image data, wherein a region with low luminance in the second image data is determined to be the region other than the second document region,
- eliminating, from the second image data a region other than a second document region corresponding to the second surface of the original document;
- generating, for printing on a single surface of a recording medium, a printing image including:
- the first read image with the region other than the first document region eliminated, and the second read image with the region other than the second document region eliminated;
- and
- printing the generated printing image on a single surface of a recording medium.
