Abstract:
An electronic copying machine for making a hard copy of a remote surface has a taking lens for forming an image of the remote surface and an image sensor which scans the image to provide video signals. The electronic copying machine is provided with a scanning area projecting device for projecting a frame onto the remote surface which defines an area of the image of the remote surface to be scanned. The scanning area projecting device comprises a frame slit plate formed with a plurality of frame slits for forming different sizes of slit frame images, a masking plate for selectively masking the frame slits and a source of illumination for illuminating the slit plate so as to project onto the remote surface a frame image of a size selected by the masking plate.
Abstract:
A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document placed on the document table. The reading section includes a sensor for detecting variations of brightness within a selected reading area of the document which is designated by light beams prior to a reading operation. This apparatus further comprises a display device for displaying the image of the selected reading area.
Abstract:
Special holder for combination of an umbilical type scanner with an inking highlighter in an integral or piggy back unit, which upon use provides a visual record of what has been scanned as well as "scan field verification" which obviates the need to continuously call up the computer display to determine the scan accuracy. The use of a highlighter improves the contrast between the print and the background paper (or other substrate), particularly in the case of poor quality paper, such as newsprint or recycled paper. This results in a "cleaner" digital signal and higher degree of scan accuracy, i.e. a better recognition read by the graphics/text software. Several embodiments of special holders are shown, a principal one being a side-by-side (tandem) pair of sleeves joined by a web, one sleeve being adapted to hold a conventional pen or wand-type scanner, and the other adapted to hold a conventional highlighter. In alternate embodiments a special "donut" holder comprising a cylinder with a felt highlighter tip is provided into the axial bore of which is inserted a conventional or specially designed scanner. In still another embodiment an angled highlighter may be clipped to a wand-type scanner. Scanning may be done with the highlights proceeding or trailing the scanner in the case of the arrangement. In the case of the "donut" type scanner/highlighter, the highlighting procedes the scanning, and the unit is omni-directional.
Abstract:
An image forming apparatus for forming an image on papers in response to the image information of an original on an original table is provided with a reading unit for scanning the original, and also with x- and y-direction moving mechanisms for moving the reading unit two-dimensionally at the time of scanning operation. The x- and y-direction moving mechanisms are provided with first and second carriages for holding and moving the reading unit in x- and y-directions. X- and y-direction display lines are put down on the first and second carriages, respectively. When the first and second carriages are moved, therefore, their display lines display on the original table an image forming area which the reading unit can read.
Abstract:
A system and method for processing an image of a document is disclosed. The method includes receiving at least one predetermined document parameter of the document. An image of the document is previewed on a display using a camera. The display provides a visual indication of a defect in the image based on the preview. A processor proposes a procedure to minimize the defect in the image. A user adjusts the camera in response to the proposal. The processor processes the image of the document.
Abstract:
A portable document scanner that records both image and voice information, comprises a digital camera module (101) configured to capture document images, and a laser frame generator (106) configured to project a visible beam of light forming a laser frame (205) to indicate the corresponding field of view of the optical lens for framing a document (206) to be captured. A light source generated by a laser diode (202) is shaped by passing through a collimating optical element (203) and a diffractive optical element (204) which is configured to produce a visible laser frame for framing a document to be captured. The captured data is then stored in an internal memory of the scanner. A data connector (117) is permanently attached to the scanner body, which is used to connect the scanner directly into a receptacle on an external device (303) for accessing data. After the data connector has thus connected the scanner to the external device, the captured data can be transferred through the data connector from the internal memory of the scanner to the external device. The data connector can be either separately sheathed with a protective outer cap (301) to serve as an attachment to keychain; or separately integrated with a pen mechanism (400) to serve as a writing instrument when carried by user for daily use.
Abstract:
A device and method for scanning an object on a working surface, the device comprising: a body located adjacent to the working surface; two or more cameras mounted on the body at a location elevated adjacently above the working surface for capturing images of the object on the working surface, the two or more cameras being angled such that their range of image captures overlap and the common overlapping region of the range of image captures of the two or more cameras corresponds with the size of the working surface, the two or more cameras being spaced apart such that each of the two or more cameras captures a different angle of the common overlapping region; and a processing unit capable of correcting skewed images of the working surface captured by the two or more cameras and capable of converting the images captured by the two or more cameras into a three dimensional image.
Abstract:
Es wird ein System zur digitalen Dokumentenerfassung und -speicherung beschrieben, umfassend einen Standfuß (1) mit einem gelenkig daran angreifenden Tragarm (2) und eine Digitalkamera (3), welche einen mittels einer optischen Positionierungshilfe (4) anzeigbaren Bildaufnahmebereich (5) aufweist und an eine elektronische Datenverarbeitungsvorrichtung (6) angeschlossen ist. Die Aufgabe der Erfindung besteht darin, ein System zur digitalen Dokumentenerfassung und -speicherung zu entwickeln, dass auf einfache Weise bereits während des Lesens eines Dokumentes ein exaktes Ausrichten zur elektronischen Erfassung ermöglicht und dabei eine Datei erzeugt, deren Darstellung des Dokumentes qualitativ weit gehend dem Original entspricht. Die Aufgabe wird mit einem System gelöst, bei dem die Digitalkamera (3) eine Bildauflösung von mindestens 2 Millionen Bildpunkten aufweist und die optische Positionierungshilfe (4) ein einziger Laser ist, welcher mittels einer Optik eine Umrandung des Bildaufnahmebereichs (5) mit vier Anlegekanten (7a-d) anzeigt.
