Abstract
A document size detecting apparatus includes a first acquisition unit, a second acquisition unit, and a detector. The first acquisition unit acquires a first image that is an image of an entire document as a reading target. The second acquisition unit acquires a second image that is an image of a part of the document read by a first reading apparatus. The detector detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.
Claims19
A document size detecting apparatus comprising:
- a processor configured to function as:
- a first acquisition unit that acquires a first image that is an image of an entire document as a reading target;
- and
- a second acquisition unit that acquires a second image that is an image of a part of the document read by a first reading apparatus;
- and
- a detector that detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.
A non-transitory computer readable storage medium storing a program that causes a computer to execute a document size detection process, the process comprising:
- acquiring a first image that is an image of an entire document as a reading target;
- acquiring a second image that is an image of a part of the document read by a first reading apparatus;
- and
- detecting a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.
An image processing system comprising:
- a document size detecting apparatus;
- a first reading apparatus;
- and
- an image synthesis apparatus, wherein
- the document size detecting apparatus includes
- a processor configured to function as:
- a first acquisition unit that acquires a first image that is an image of an entire document as a reading target, and
- a second acquisition unit that acquires a second image that is an image of a part of the document read by the first reading apparatus, and
- a detector that detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus,
- the first reading apparatus includes a reader that reads the document, and
- the image synthesis apparatus includes a synthesizer that synthesizes a plurality of images read by the first reading apparatus.
