    Abstract: A framing aid for a handheld document capture device such as a digital camera, comprising two pattern generators (10,20) generating convergent patterns (14, 24) that are in register on a target object plane. Triangulation between the two pattern generators (10,20) and using superimposed or complementary patterns (14,24) ensures that the hand held device (1) is correctly arranged at a predetermined range and orientation above a document to be captured, such that the document is accurately framed within the field of view of the capture device (1).

    Abstract: A system and method of obtaining a reconstructed digital image of an image that is projected, displayed, or printed on a surface by capturing a single digital image of the surface is described. According to the system and method, at least three illumination marks are projected onto the surface. The illumination marks have a particular detectable characteristic. An image captures a single image of the surface including the illumination marks to obtain captured image data. The location and the pixel values corresponding to the illumination marks are detected dependent on the particular characteristic of the illumination mark pixels in the captured image data. The locations of the illumination marks are then used to correct for distortion of the image and surface in the captured image data to generate an undistorted digital image of the image on the surface. The illumination mark pixel values are replaced within undistorted digital image with estimated pixel values that are determined using neighboring non-illumination mark pixel values.

    Abstract: Scanner apparatus include a scanner having a scanbed that is positioned to place an object to be scanned in a scan field of the scanner. A configurable field segmentor is positioned adjacent the scanbed that demarcates a plurality of fields within the scan field. The field segmentor may be one or more scan guides configured for placement in one of a plurality of demarcation locations adjacent the scanbed. Alternatively, the field segmentor may be one or more templates configured for placement adjacent the scanbed.

    Abstract: An apparatus may include a transparent platen, a command interface, a scanner unit, a controller and an indicator. The command interface is to receive externally originating instructions including a selected scaling value, other than 100%, for a scanning operation of a document resting against the transparent platen, wherein contents of the document to be scanned are proportionally magnified or shrunk based on the selected scaling value The controller controls a scanner unit to capture a portion of the transparent platen, the portion having borders automatically determined and proportionally changed by the controller based upon the selected scaling value. The indicator provides a visible indication of the portion.
