Abstract
There is provided a scanner including: a first light source that generates light of a first wavelength; a mark that emits light in a case where light of the first wavelength is received; a deviation calculation section that calculates a deviation between a plurality of sensors based on sensor outputs acquired in such a way that the sensors detect light emitted from the same mark; a second light source that generates light which does not include light of the first wavelength; and an image generation section that generates image data based on the sensor outputs, acquired in such a way that the plurality of sensors detect light acquired when light from the second light source is stuck on and is reflected in the document, and the deviation.
Claims6
A scanner, which scans a document using a sensor, the scanner comprising:
- a first light source that generates light of a first wavelength;
- a mark including a material that emits light in a case where light of the first wavelength is received;
- a deviation calculation section that calculates a deviation between a plurality of sensors based on sensor outputs acquired by the sensors that detect light emitted from the same mark;
- a second light source that generates light which does not include light of the first wavelength;
- and
- an image generation section that generates image data based on the deviation, and the sensor outputs acquired by the plurality of sensors that detect light generated by the second light source and reflected on the document.
A method of generating image data comprising:
- irradiating a mark, including a material which emits light in a case where light of a first wavelength is received, with light of a first wavelength from a first light source;
- calculating a deviation between a plurality of sensors based on sensor outputs acquired by the sensors that detect light emitted from the same mark;
- and
- irradiating a document with light from a second light source that generates light which does not include light of the first wavelength, and generating image data based on the deviation, and the sensor outputs acquired by the plurality of sensors that detect light generated by the second light source and reflected on the document.
