    Abstract: A multifunction peripheral includes a scanning platform, a scanning module, a recording unit and a controlling unit. The scanning platform includes a standby position, a position-calibrating structure and a datum line. The scanning platform is divided into a first zone and a second zone by the datum line. The position-calibrating structure is included in the second zone. The scanning module is movable with respect to the scanning platform for performing a scanning operation. The recording unit is used for recording a parameter associated with a position of the scanning module with respect to the scanning platform. The controlling unit is used for controlling movement of the scanning module according to the parameter recorded in the recording unit, so that the scanning module is moved through the position-calibrating structure to perform a position-calibrating operation. After the position-calibrating operation is completed, the scanning module is moved to the standby position.

    Abstract: In one embodiment, an image forming apparatus: forms, on both sides of a reference chart sheet 10, reference positioning images which are determined in advance relative to reference positions on both sides of the reference chart sheet 10; reads reference images through the image readable area from a plurality of parts on both sides of the reference chart sheet 10 or from the folded reference chart sheet 10; and adjusts image forming positions on both sides of a paper according to read-out information obtained from the reference images. The image forming positions are corrected on both sides of the paper which is greater in size than the image readable area of the image reader 11 by reading the images from multiple parts of the reference chart sheet 10 or from the folded reference chart sheet 10.

    Abstract: A document camera is described for capturing an electronic image of a document, for subsequent optical character recognition. In order to avoid the need for a user to look through a viewfinder of the camera, the camera comprises a projector for projecting an optical field of view indicator on to the document. The user can see the projected indicator on the document page, indicating the effective field of view of the camera. The camera may include auto-focus and zooming mechanisms. In one form, the camera processes a detected image to determine a capture zone corresponding to whole regions of the document falling entirely within the field of view. The projected indicator is controlled to indicate only the capture zone. When the image is to be captured, the camera zooms in to the capture zone to capture the image at maximum resolution.
