A system and computer-implemented method for calibrating a document processing device from a composite document is disclosed. A composite document including human-readable content and machine-readable code marks is input into a document processing device. The machine-readable code marks are decoded to identify at least one spatial pointer including at least one nominal property of at least a portion of the human-readable content. The at least one nominal property is compared to an input property of the human-readable content. One or more distortions in the input property compared to the at least one nominal property are identified. The document processing device is calibrated based on the identified distortions.

A method and apparatus is disclosed for generating and distributing multilingual documents. The multilingual documents are comprised of primary information consisting of human-readable text and secondary information consisting of machine-readable data such that a translation of the text is accomplished by converting the human-readable text into a second language through the use of the decoded machine-readable data. The machine-readable data is comprised of a code that describes a set of editing operations that can be applied to the human-readable text to convert it into at least a second language. In a preferred embodiment, the machine-readable data is embedded in the image using an unobtrusive code on the document such as Xerox DATAGLYPH codes.

Recorded video is accessed from printed notes or summaries derived from the video. Summaries may be created automatically by analyzing the recorded video, and annotations are made by a user on a device for note-taking with digital ink and video. The notes and/or summaries are printed along with data glyphs that provide time based indexes or offsets into the recorded video. The indexes or offsets are retrieved by scanning the glyph on the printout. The glyph information can be embedded in the printouts in many ways. One method is to associate block glyphs with annotations or images on the printed pages. Another method is to provide an address carpet in an annotated timeline. Yet another method is to provide a two-dimensional address carpet with X-Y position mapped to time which can be used to provide selected access to the video. The accessed video may be played back on the note-taking device on a pen computer, or on a summary interface on a Web browser-type device.

System and method for video access from notes or summaries

In accordance with one aspect of the present exemplary embodiment, provided is a hand-held printer system and method for printing on a target. The system includes a hand-held printer, a target position sensing system which senses a position of the target, and a hand-held printer position sensing system which senses a position of the hand-held printer relative to a printing surface of the target. A control mechanism actuates the printing of the hand-held printer based on the sensed positions.

A method for reconstructing three dimensional shapes from two dimensional image domains uses glyph address carpets as a structured light pattern. The glyph address carpet includes a glyph encoding scheme in which the coordinates of any given point can be computed by looking at the glyph marks in a small neighborhood. The method includes calibrating at least one projecting device and at least one image detecting device and projecting a glyph address carpet pattern onto a three dimensional figure. The projected glyph address carpet pattern is detected and used to reconstruct the three dimensional coordinates for each readable glyph mark within the projected glyph address carpet pattern.

A beam position control system controls a position of a beam directed from a beam source. The beam position control system includes a beam position sensing system that generates one or more satellite beams which are used to determine the position of a main beam. A beam offset computation block determines a relative position of the main beam with respect to a desired main beam position and provides beam offset information to a controller that generates a compensation signal used to adjust the main beam position to the desired main beam position via a beam actuation system.

An embedded data code comprises periodic tiles having occlusions. In one embodiment, each tile is comprised of glyphs encoding a first code system. The occlusions are comprised of information, such as glyphs encoding a second code system, graphics, or text. The occlusions may occur periodically in each tile. A reading device may be used to capture an image of a portion of the substrate that includes a tile. A processor then analyzes the image to determine the tile code pattern and decode the tiled code.

A directed beam position sensing system and method includes a beam source configured to emit a beam. A satellite beam generator is aligned to receive the beam and to transmit a main beam portion and to generate a pair of symmetrically positioned satellite beams. A first detector arrangement is positioned to detect a first satellite beam of the pair and to generate a first detector signal. A second detector arrangement is positioned to detect a second satellite beam of the pair, and to generate a second detector signal, wherein the first detector signal and the second detector signal are used to determine a position of the main beam. In accordance with another aspect of the present application, further provided is a second pair or satellite beams, wherein the first pair of satellite beams is generated at one of an x axis or a y axis, and the second pair of satellite beams is generated in the other axis. The first pair of satellite beams and second pair of satellite beams being perpendicular to each other and including third and fourth detectors to detect the position of the satellite beams. In a further embodiment of the present application, a beam position sensing system includes a beam source configured to generate a directed beam. A satellite beam generator is aligned to receive the directed beam and to transmit a main beam and generate a single-sided satellite beam at a known position. A detector arrangement positioned to detect the satellite beam generates a detector signal. The detector signal is then used to determine the position of the main beam. In accordance with another aspect of the present application, the satellite beam generator is a scanning satellite beam generator which scans the satellite beams, while transmitting a main beam substantially undisturbed.

A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

A system and method for generating information based on decoded embedded data from a substrate is implemented by reading embedded data from a substrate, decoding the embedded data to determine registration of the substrate relative to a reference in an apparatus, and developing and presenting human-sensible information based on the registration information. In one embodiment, the human-sensible information is visual information registered with the substrate. The human-sensible information may also comprise, for example, tactile, audible, or other sensory information.

This invention provides self-clocking glyph shape codes for encoding digital data in the shapes of glyphs that are suitable for printing on hardcopy recording media. Advantageously, the glyphs are selected so that they tend not to degrade into each other when they are degraded and/or distorted as a result, for example, of being photocopied, transmitted via facsimile, and/or scanned-in to an electronic document processing system. Moreover, for at least some applications, the glyphs desirably are composed of printed pixel patterns containing nearly the same number of ON pixels and nearly the same number of OFF pixels, such that the code that is rendered by printing such glyphs on substantially uniformly spaced centers appears to have a generally uniform texture. In the case of codes printed at higher spatial densities, this texture is likely to be perceived as a generally uniform gray tone.Binary image processing and convolution filtering techniques for decoding such codes also are disclosed, but this application focuses on the codes.

A viewport lens displays registered information registered using embedded data. An image capture device captures an image from the substrate that includes embedded data. The embedded data in the captured image is decoded to create information regarding the substrate, such as location, orientation, or a label. Based on the information regarding the substrate, information is generated that is registered with the substrate. In one embodiment, the information is registered with the substrate by optically combining the generated information with substrate information in a viewport lens.

A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.
