摘要： An image reading device includes a shooting unit, a light source unit, a shooting controller, and a combining unit. The light source unit sequentially irradiates the bound document with light from first and second irradiation positions opposing each other with respect to a first straight line orthogonal to a direction of a binding portion of the document. The shooting controller controls the shooting unit to shoot a first region positioned at the second irradiation position side on the document when the light source unit irradiates the document with light from the first irradiation position, and controls the shooting unit to shoot a second region containing a region other than the first region on the document when the light source unit irradiates the document with light from the second irradiation position. The combining unit combines a shot image of the first region and a shot image of the second region.

摘要： A system including a Multi Function Printer/Product/Peripheral (MFP) and a portable computing device adapted to allow automatic copying of documents by the MFP from the portable computing device. The portable computing device includes a display, a plurality of sensors for detecting light, a light detection module and a page changing module. The sensors are positioned to detect light from the MFP and trigger a page change automatically. The MFP in accordance with the present invention includes a scanner with a platen, a page change detection module, an image processing module, a device identification module, and a document matching & retrieval module. The page change detection module is adapted to receive the images presented by the portable computing device on the platen of the scanner for copying. The page change detection module detects changes and causes the MFP to scan and output a copy. The MFP may also use image processing techniques to locate an original version of the document on a server and print that higher quality document, instead of the scan from the portable computing device.

摘要： An image-reading device includes a document-supporting base, a document-pressing member, a reading unit, a controlling unit, and a determining unit The document-supporting base has a transparent member on which a document is placed. The document-pressing member is disposed on the document-supporting base so as to cover the transparent member. The document-pressing member is capable of opening and closing on the document-supporting base. The reading unit has a light source and capable of reading an image from the document placed on the transparent member while the light source irradiates light on the document. The controlling unit is configured to control the reading unit to execute a first scanning operation to output image signals for the image on the document while the light source is lit, and a second scanning operation to output image signals for the image on the document while the light source is not lit. The determining unit is configured to determine whether outside light has penetrated the document-supporting base based on the image signals for the second scanning operation outputted from the reading unit.
