An imaging system is configured to capture images of both obverse and reverse sides of a collectible item using a single image captured by a single camera. The reflective faces of two flat mirrors are positioned at a 90-degree angle, and a collectible item is positioned and secured between the mirrors such that parallel faces of the item or its case are oriented at a 45-degree angle between the flat mirrors. A camera is mounted to face the mirrors with its perspective being parallel to the faces of the item, looking into the mirrors. The camera can see mirrored reflections of both faces of the item simultaneously from a single perspective and can capture views of both faces in a single camera image. The single image can then be cropped and reverse-mirrored automatically or manually in software to extract images of the obverse and reverse sides of the item.

An image processing apparatus including: a document table on which at least one document is arrangeable; an image input unit reading the document arranged on the document table; an individual image extractor extracting image data read by the image input unit on a document basis to obtain image data of an individual image; a storage storing association information between an arrangement status of the document with respect to the document table and a reading surface of the document to be read by the image input unit; an arrangement status determiner determining the arrangement status of the document with respect to the document table on the basis of the image data of the individual image; and a reading surface determiner determining the reading surface of the document read by the image input unit on the basis of the association information and the arrangement status determined by the arrangement status determiner.

An image scanning apparatus comprises: a first image scanning unit that performs image scanning of a first surface of an original; a second image scanning unit that performs image scanning of a second surface of the original; and a control unit that controls output channels for outputting analog signals from the first image scanning unit, wherein the control unit changes, between a case of single-sided scanning and a case of both-sided scanning, the output channels of the analog signals output from a part of scanning region in a plurality of scanning regions of the first image scanning unit, and changes, between a case of single-sided scanning and a case of both-sided scanning, the number of output channels for outputting the analog signals from the first image scanning unit.

A two-sided scanning device includes a first image scanning module, a second image scanning module, a first scanning background component, a first brightness calibration component, a second scanning background component, and a second brightness calibration component. When the second image scanning module moves relative to the first image scanning module to a scanning position, the second image scanning module drives the first scanning background component to move relative to the first image scanning module, so that the first image scanning module and the second image scanning module are aligned with the first scanning background component and the second scanning background component, respectively. Therefore, the first scanning background component and the second scanning background component can be scanning backgrounds for the first image scanning module and the second image scanning module to generate a scanning image of an object with a size corresponding to an actual size of the object.

An image reading apparatus includes a shooter where a first mounting surface that is inclined with respect to a horizontal plane is formed thereon, a stacker, a supporting unit that movably supports the stacker in such a manner that the stacker is arranged in a first region or a second region, a conveyance unit that conveys a document from the shooter to the stacker when the stacker is arranged in the first region, and a reading unit that reads an image from the document when the document is conveyed by the conveyance unit, wherein a surface area of a region of the first mounting surface that is covered by the stacker when the stacker is arranged in the first region is greater as compared with that when the stacker is arranged in the second region, and the stacker is formed to be capable of being lengthened or shortened.

An image forming apparatus includes an image scanning device, which comprises: a document tray to load an original document to be scanned; a discharge tray to load the original document after being scanned; and a frame which the document tray and the discharge tray are mounted on. A conveyance path is formed inside the frame to connect the document tray and the discharge tray. The frame contains a conveying structure to convey the original document along the conveyance path; a transparent support member located below the conveyance path to support the original document; a scanning member located below the transparent support member, the scanning member having a scanning position in which the scanning member scans the original document when being located on the transparent support member; and a pressing member disposed above the transparent support member and facing the scanning member for pressing the original document onto the transparent support member.

An image forming apparatus temporarily stores, in an image memory, image data generated by a front surface reading unit and a back surface reading unit for reading images of a front surface and a back surface of an original respectively. A CPU of an image forming apparatus, at a time of starting a copy job, sets an output frequency of the image memory (transfer rate of image data) to a first frequency F1 that is lower than a second frequency F2. The CPU sets the output frequency of the image memory to the second frequency F2 when transfer of the image data of the first page which corresponds to the front surface of a first original completes.

In accordance with an embodiment, an image processing apparatus comprises a front surface reading section, a back surface reading section, a back surface image processing section and a front surface image processing section. The front surface reading section reads a range containing a front surface of a sheet. The back surface reading section reads a range containing a back surface of the sheet. The back surface image processing section detects a position of a sheet part in back surface image data based on the back surface image data obtained by reading the sheet back surface. The front surface image processing section extracts an image on the sheet part from front surface image data obtained by reading the sheet front surface based on the position of the sheet part in the back surface image data.

The front surface image processing section extracts an image on the sheet part from front surface image data obtained by reading the sheet front surface based on the position of the sheet part in the back surface image data.

An image reading device includes a first unit to read one surface of a document in a first area facing a document path, a second unit disposed in the first area to read the other surface of the document, a first reference member facing the first unit at a first distance therefrom at a second position in a second area not facing the path, a second reference member facing the first unit at a second distance therefrom at a first position in the first area, a third reference member facing the second unit at the second distance therefrom, and a correction unit to correct, based on a difference between first data generated through reading of the first member by the first unit and second data generated through reading of the second member by the first unit, third data generated through reading of the third member by the second unit.
