Definitions

  • the present invention relates to devices and methods for reproducing images and, more particularly, to improved devices and methods for imaging three-dimensional objects.
  • Systems and methods for scanning two-dimensional images of objects are regularly used in many home and office applications.
  • Typical systems can include photocopiers, facsimile machines, flatbed scanners connected to computers via Universal Serial Bus (USB) cables, or others.
  • These systems and methods can generally involve placing an object to be scanned (such as a document, photograph, book or other item), onto a flat, substantially transparent flatbed surface (such as glass) positioned within an enclosure.
  • a light source and a photographic means for recording images are positioned beneath the transparent flatbed surface.
  • the light source illuminates the object to be scanned is illuminated as the photographic means captures a two- dimensional duplicate or replica image thereof.
  • Many such systems and methods for scanning contemplate instantly illuminating the entire object as the image is captured, as with a flash from a conventional camera, while other systems and methods involve illuminating portions of the object as images of portions of that object are recorded.
  • Flatbed scanning systems and methods are generally used to capture substantially accurate two-dimensional image of objects, and the reproduced images can be used in any number of ways.
  • everyday photocopiers can duplicate paper items or photographs and reproduce them in print form.
  • Facsimile machines can capture and transmit duplicates of documents or images to distant end users via standard communication lines, such as by telephone or the Internet.
  • Computer scanners can record digital images to be reproduced in print form or for use in digital form, in video or computer applications such as World Wide Web pages or sites.
  • flatbed scanning systems and methods involve the projection of light from one direction (typically, from beneath the object disposed on the flatbed) as the object is scanned,
  • MEl 7180762v.l these systems and methods are very effective when the object to be scanned is paper (such as a document or picture) or another substantially flat object (such as a book).
  • their efficacy is limited when the object to be scanned is three-dimensional in nature, or has features on more than one plane.
  • the primary reason for this phenomenon is that illumination is provided to the object from only one plane within the scanner enclosure, usually from beneath the flat transparent flatbed surface, with the object resting thereon.
  • flatbed scanning systems and methods of the art can recreate accurate images of photographs, documents or pages from a book or a magazine, wherein all of the features desired for duplication are substantially located on one plane, and that plane is disposed flush against the transparent flatbed surface.
  • Described herein is a device for the improved photographic imaging of three- dimensional objects using flatbed scanning systems and methods of the art by providing an
  • the present invention includes an illumination assembly (herein, a "light box") to be positioned above or around an object that has been placed in or on a standard photocopier, facsimile machine, computer scanner, or comparable system for capturing two-dimensional images.
  • the illumination assembly improves the performance of existing systems by shining additional light onto the object from at least one additional angle as the object is scanned, thereby complementing the light originating from beneath the flatbed surface, and improving the quality of the image that is ultimately recorded.
  • the present invention also provides an improved method for scanning three- dimensional objects by shining light onto the object from multiple angles or directions while recording an image of the object.
  • FIG. 1 is a front perspective view of an illumination assembly according to an embodiment of the present invention, with a cutaway showing a typical object to be scanned.
  • FIG. 2 is a view of a typical object subject to light from different directions, placed on a flatbed in accordance with an embodiment of the present invention.
  • the present invention is based on the surprising and unexpected discovery that providing additional light, for example, light from at least one other source, to a three-dimensional object to be scanned enhances the quality of the image produced by an electronic imaging device, for example, a flatbed scanning apparatus.
  • a light box 10 comprising a housing assembly 18 having a body portion that defines a plurality of faces and an internal chamber, is positioned above an object 12 to be scanned on the flatbed 14 of a conventional
  • the exemplary light box 10 provides illumination from above the object 12 in addition to light that is also provided by the scanning device 16, thereby improving the quality of the image recorded by the scanning system.
  • the light box 10 comprises a housing assembly, and an illumination assembly 20 having a light source.
  • the illumination assembly 20 comprises a plurality of fluorescent lights 22.
  • the additional light can be provided from one or more light producing sources, including, for example, halogen, laser, light emitting diode (LED), incandescent, and the like.
  • FIG. 1 The effect of the additional light source on an object 12 to be imaged by a standard photocopier 14 with a rolling photography apparatus is shown in FIG. 2.
  • Intrinsic light flux from the photocopier's internal scanning system is shown in the direction U.

By illuminating more of the object, and from different angles, the quality of an image that is ultimately produced or recorded of the object is enhanced.
  • FIG. 1 features a frame and a light source directing light downward from above the object 12, the present invention is not limited as such. Additional embodiments are contemplated, which include incident light sources directing light from one or more sides in addition to or instead of the top, and includes combinations thereof.

Additionally, the light source of the present invention need not cover the entire the entire transparent flatbed surface of the scanner, and the light source is not limited to purely "white" light. It is expressly contemplated that the light may be of any color, intensity, wavelength, strength. In addition, the light may be emitted from the light source for any suitable duration.

  • the light box 10 may be completely or partially attached to the scanner, for example, with a hinge or other form of connection, to act as a lid or cover over the flatbed 14.
  • the light source need not be illuminated when two-dimensional objects (such as documents) are copied, but may be selectively energized when certain three-dimensional objects are imaged.
  • the light source may be internally wired to draw power from the same source as the scanning device 16, or from any other power source, and can be actuated from an integrated system that can control both the scanning device 16 and the light source.

Abstract

La présente invention concerne un ensemble imageur destiné à être utilisé avec un système standard à plat, comme un photocopieur, un télécopieur, ou un numériseur informatique par exemple, qui permet de capturer des images en deux dimensions d'objets en trois dimensions. L'ensemble fournit une source de lumière supplémentaire qui doit être projetée sur des objets au moment où ils sont numérisés, ce qui permet d'améliorer la qualité de l'image produite lorsqu'un objet volumineux ou à plusieurs facettes est numérisé. L'ensemble peut être un système indépendant, autonome, auto-alimenté, ou bien il peut être entièrement intégré à un système standard à plat, soit lors de la construction du système à l'origine, soit comme un accessoire supplémentaire destiné à être utilisé dans certains cas.
