Abstract
A system and method for aligning documents for scanning includes a multifunction peripheral with a 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.
Claims20
A multifunction peripheral comprising:
- a controller including a processor and associated memory;
- a scanner operable in accordance with instructions received from the controller;
- an uncovered 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 uncovered scan platen,
- wherein the processor is configured to determine an optimal position and angular orientation of the tangible document relative to the scan platen in accordance with document boundary areas or text orientation determined from a captured digital image and currently selected paper size;
- 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;
- the processor further configured to capture at least a second digital image of the tangible document after repositioning thereof in accordance with the directed repositioning and rotation;
- and
- the processor further configured to complete a scan operation when a digital image of the tangible is captured with the optimal position and angular rotation while the scan platen is covered.

A method comprising:
- receiving digital image input from a sensor indicative of a position and angular orientation of a tangible document on a uncovered scanner platen;
- determining from the digital image and currently selected paper size, via a processor and associated memory, an optimal position and angular orientation of the tangible document relative to the scanner platen;
- 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;
- covering the scanner platen and tangible document capturing at least a second digital image of the tangible document in the covered platen after repositioning thereof in accordance with the directed repositioning and rotation;
- and
- completing a scan operation when a digital image of the tangible document is captured with the optimal position and angular rotation.
3 more elements
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 obtained from a scan of the tangible display on an uncovered 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 currently selected paper size,
- 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,
- the processor further configured to capture at least a second digital image of the tangible document with the platen covered after repositioning thereof in accordance with the directed repositioning and rotation, and
- the processor further configured to complete a scan operation when a digital image of the tangible document is captured with the optimal position and angular rotation.
