Abstract

A system and method for aligning documents for scanning includes a multifunction peripheral with an intelligent controller having a processor and associated memory. The controller issues instructions controlling operation of a scanner. A tangible document is placed on a surface of a scanner platen, and a sensor determines its location relative to the platen. An optimal position of the document relative to the platen is determined. The processor then generates a graphical rendering on an associated display indicative of a directed repositioning of the document on the platen in accordance with a determined optimal position of the document relative to the platen.

Claims

1. A multifunction peripheral comprising:

an intelligent controller including a processor and associated memory;

a scanner operable in accordance with instructions received from the intelligent controller;

a scan platen configured to receive a tangible document on a surface thereof; and

a sensor configured to capture a digital image associated with a position and angular orientation of a received tangible document relative to the scan platen,

wherein the processor is configured to determine an optimal position and angular orientation of the tangible document relative to the scan platen; and

the processor further configured to generate a graphical rendering on an associated display indicative of a directed repositioning and rotation of the tangible document on the scan platen in accordance with a determined optimal position of the tangible document relative to the scan platen.

2. The multifunction peripheral of claim 1 wherein the scanner comprises the sensor.

3. The multifunction peripheral of claim 2 further comprising a display comprised of a touchscreen display comprising a user interface of the multifunction peripheral.

4. The multifunction peripheral of claim 1 further wherein the sensor is comprised of a digital camera, and wherein the processor is further configured to determine the angular rotation in accordance with a linear property of the tangible document.

5. The multifunction peripheral of claim 4 wherein the digital camera is integrated into a portable data device directed to the scan platen.

6. The multifunction peripheral of claim 5 wherein the display is integrated into the portable data device.

7. The multifunction peripheral of claim 6 wherein a processor associated with the portable data device generates an image of the scan platen and tangible document with a concurrent augmented reality graphic indicative of the directed repositioning of the document relative to the image of the scan platen.

8. The multifunction peripheral of claim 1 further comprising:

a paper feeder storing paper stock of a known size,

wherein the processor is further configured to generate the graphical rendering in accordance with a depiction of a positioning of an image of the tangible document relative to an image corresponding to the size of the paper stock.

9. A method comprising:

receiving digital image input from a sensor indicative of a position and angular orientation of a tangible document on a scanner platen;

determining, via a processor and associated memory, an optimal position and angular orientation of the tangible document relative to the scanner platen; and

generating a graphical rendering on an associated display indicative of a directed repositioning and rotation of the tangible document on the scanner platen in accordance with a determined optimal position of the tangible document relative to the scanner platen.

10. The method of claim 9 further comprising generating, via the sensor, data indicative of a position of the tangible document on the scanner platen.

11. The method of claim 10 further comprising generating the graphical rendering on a touchscreen display comprising a user interface of a multifunction peripheral.

12. The method of claim 9 further comprising capturing a digital image of the tangible document via a sensor comprised of a digital camera, and determining the angular rotation in accordance with a linear property of the tangible document.

13. The method of claim 12 wherein the digital camera is integrated into a portable data device directed to the scanner platen.

14. The method of claim 13 wherein the display is integrated into the portable data device.

15. The method of claim 14 further comprising generating an image of the scanner platen and the tangible document on the display with a concurrent augmented reality graphic indicative of the directed repositioning of the tangible document relative to the image of the scanner platen.

16. The method of claim 9 further comprising:

storing paper size data indicative of a size of paper stock disposed in an associated sheet feeder; and

generating the graphical rendering in accordance with a depiction of a positioning of an image of the document relative to an image in accordance with the paper size data.

17. A system comprising:

a digital camera configured to capture a digital image of a tangible document disposed on a surface of a scanner platen;

a display; and

a processor and associated memory,

the processor configured generate a document image of the tangible document on the display, wherein a position of the document image on the display corresponds to a position and angular orientation of the tangible document on the scanner platen,

the processor further configured to define an adjusted position and angular orientation of the tangible document on the scanner platen in accordance with the captured digital image, and

the processor further configured to generate a graphical indicator on the display indicative of a movement and rotation of the tangible document relative to the surface of the scanner platen in accordance with a defined, adjusted position.

18. The system of claim 17 wherein the adjusted position of the tangible document is further defined in accordance with a paper dimension associated with printout paper used by a multifunction peripheral comprising the scanner platen.

19. The system of claim 18 wherein the processor is further configured to generate a border corresponding to the paper dimension on the display concurrently with the graphical indicator.

20. The system of claim 17 wherein the processor is further configured to generate an image of the scanner platen on the display concurrently with the graphical indicator.
