Method of capturing an image of a document
View Patent ↗A document scanner ( 10 ) includes an input tray ( 30 ) for holding documents ( 20 ) and an input image capture device ( 40 ) for capturing images of the documents ( 20 )in the input tray ( 30 ) prior to transporting the document for imaging; an output tray ( 150 ) for holding documents ( 20 ) after the documents ( 20 ) exit the scanner; an output image capture device ( 140 ) for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents ( 20 ) before imaging and after the documents ( 20 ) exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.
1. A method of capturing an image of a document comprising:
providing an input tray for holding documents;
capturing an image of a first document in the input tray with an input imaging device;
wherein the input tray image of the document is captured as an area image;
transmitting the captured input tray image of the document to an image processor;
transporting the document to an output tray.
2. The method as in claim 1 comprising:
capturing an image of the document in the output tray with an output imaging device;
transmitting the captured output tray image of the first document to the image processor; and
verifying the accuracy of the input tray image of the document by comparing the input tray image of the document to the output tray image of the document.
3. The method as in claim 1 comprising:
capturing an image of a second document in the input tray with the input imaging device;
wherein the input tray image of the second document is captured as an area image;
transmitting the captured input tray image of the second document to the image processor; and
verifying the accuracy of the input tray image of the second document by comparing the input tray image of the second document to the output tray image of the second document.
4. The method as in claim 2 comprising:
modifying scanner functions if the raster scanned image of the document does not match the input tray image of the document.
5. The method as in claim 4 wherein the scanner functions are selected from a group consisting of rotation of the raster capture device, changing a color capture mode, or cleaning image optics.
6. The method as in claim 1 wherein the input tray image of the document is high resolution.
7. The method as in claim 2 comprising:
alerting a document scanner operator if the raster scanned image of the document does not match the input tray image of the document.
8. A method of verifying accuracy of a raster scanned image of a document comprising:
transporting the document through a document scanner;
capturing a raster scanned image of the document with a raster capture device;
transmitting the raster scanned image to an image processor;
providing an output tray for holding documents;
capturing an image of a document in the output tray with an output imaging device;
transmitting the captured output tray image to the image processor; and
verifying the accuracy of the raster scanned image by comparing the raster scanned image of the document to the output tray image of the document.
