- This invention relates to scanners in general, and in particular to verifying the accuracy of a scanned document.
- a document scanner moves a document through a transport path and creates a digital image of the document as it moves.
- the processor for the document scanner has preset document characteristics and the operator must select functions and features to accommodate the specific requirements for a particular type of document. Alternately, the scanner may default to less efficient settings that will process all documents since scanners are not typically programmed with specific requirements on a document-by-document basis.
- the preset characteristics include document characteristics such as size, weight, texture; and specific application requirements such as resolution and imaging mode, color, simplex, or duplex.
- the documents to be scanned may vary by size, weight, color content, physical condition, or other characteristics, which may require different scanner features to be enabled or operator actions to be employed for the most optimal and efficient mode of operation.
- Prior knowledge of these many different document attributes can enable the proper selection of scanner features to improve the efficiency of the scanning process or enable other features which may provide specific applications required by a particular type, style, or size of document.
- Prior knowledge of the documents physical condition can also prompt immediate action from the operator to protect the document or scanner or allow other features within the scanner to perform more reliably.
- the exit area of the scanner is used for collecting the scanned documents as they exit the transport.
- a document must also exit the scanner, once it has been imaged, in an orderly fashion.
- the scanned document may be deformed or wrinkled by the document transport system, there may be dust or foreign matter on the image capture optics, the document may be skewed or misaligned, or incorrect scanning features may have been selected, but not limited to, all of which may result in capture of inaccurate information during the scanning process.

Also determining the output tray 150 level of documents will be used by the processor 110 to stop scanning if the output tray 150 becomes full. This may happen if the operator continues to place documents 20 in the input tray 30 while scanning without removing documents ( 20 ) from the output tray 150 .
- Another important characteristic is the stacking of the documents 20 in the output tray 150 . If the documents 20 are not laying flat, one on top of another, the processor 110 will stop the scanning process and prevent additional documents 20 from stacking improperly. Improper stacking may be an indication of the controlled output stacking 120 feature not operating properly or being inadvertently turned off. Based on the output tray 150 characteristics, proper adjustment of the output tray side guides 160 or end stop 170 will be determined.

- an image of a document 20 in an input tray 30 for holding documents 20 is captured as an area image 210 rather than raster by raster with an input imaging device 40 .
- Capturing the image as an area image 210 means that an image of the entire document 20 is taken rather than imaging the document 20 raster by raster, which is the usual way of scanning a document 20 .

- This invention relates to scanners in general, and in particular to verifying the accuracy of a scanned document.
- A document scanner moves a document through a transport path and creates a digital image of the document as it moves. The processor for the document scanner has preset document characteristics and the operator must select functions and features to accommodate the specific requirements for a particular type of document. Alternately, the scanner may default to less efficient settings that will process all documents since scanners are not typically programmed with specific requirements on a document-by-document basis.
- The preset characteristics include document characteristics such as size, weight, texture; and specific application requirements such as resolution and imaging mode, color, simplex, or duplex. In a document scanner, the documents to be scanned may vary by size, weight, color content, physical condition, or other characteristics, which may require different scanner features to be enabled or operator actions to be employed for the most optimal and efficient mode of operation. Prior knowledge of these many different document attributes can enable the proper selection of scanner features to improve the efficiency of the scanning process or enable other features which may provide specific applications required by a particular type, style, or size of document. Prior knowledge of the documents physical condition can also prompt immediate action from the operator to protect the document or scanner or allow other features within the scanner to perform more reliably.
- The exit area of the scanner is used for collecting the scanned documents as they exit the transport. A document must also exit the scanner, once it has been imaged, in an orderly fashion. By discerning document characteristics in the input area as well as the exit area, characteristics such as, but not limited to, number of documents, the exit area features which control stacking and tracking can be managed.
- During the scanning process there are a number of ways in which the information extracted from a scanned document may be inaccurate. The scanned document may be deformed or wrinkled by the document transport system, there may be dust or foreign matter on the image capture optics, the document may be skewed or misaligned, or incorrect scanning features may have been selected, but not limited to, all of which may result in capture of inaccurate information during the scanning process. There exists a need to verify captured image data, especially in high speed document scanners.
- There have been attempts in the document printing industry to verify information on printed images, but the requirements for printing a document are different than the requirements for accurate scanning of a document. For example, U.S. Publication No. 2008/0013848, discloses a line-by-line scan of a printed document to check for defects such as streaks or banding in the printed document. U.S. Publication No. 2003/0076518, discloses a printer which incorporates a CCD raster capture device which images the output tray. The captured output image is compared to data used to print the document.
- Briefly, according to one aspect of the present invention a document scanner includes verifying accuracy of a raster scanned image of a document by providing an input tray for holding documents prior to imaging; capturing an image of a document in the input tray with an input imaging device; transmitting the captured input tray image to an image processor; transporting the document through a document scanner; capturing a scanned image of the document with a raster capture device; transmitting the raster scanned 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 input tray image of the document.
- The invention and its objects and advantages will become more apparent in the detailed description of the preferred embodiment presented below.
-
FIG. 1 is a cross-sectional view from the side of a transport for a document scanner according to the present invention. -
FIG. 2 is a perspective view of a scanner output tray according to the present invention. -
FIG. 3 is a cross-sectional view from the side of a straight through transport of a document scanner according to the present invention. - The present invention will be directed in particular to elements forming part of, or in cooperation more directly with the apparatus in accordance with the present invention. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art.
-
FIG. 1 is a side cross-sectional view of adocument scanner 10. As shown inFIG. 1 ,documents 20 are first placed in theinput tray 30 of thescanner 10. The document is moved forward into thescanner 10 by theurging roller 45, then thefeed roller 50 whileadditional documents 20 are held back by theseparation roller 60. Thedocument 20 continues through thedocument transport 70, is imaged by the front and rearraster capture devices transport exit 130 into theoutput tray 150. - As, or after, the
document 20 exits thetransport 70 at thetransport exit 130, thedocument 20 and theoutput tray 150 are imaged by theoutput imaging device 140. The images are sent to theimage processor 100 to discerndocument 20 andoutput tray 150 characteristics. - One output tray 150 characteristic is whether or not there are
documents 20 present in theoutput tray 150. If theoutput tray 150 is determined to be empty theprocessor 110 will determine howmany documents 20 can be scanned before theoutput tray 150 becomes full. Also determining theoutput tray 150 level of documents will be used by theprocessor 110 to stop scanning if theoutput tray 150 becomes full. This may happen if the operator continues to placedocuments 20 in theinput tray 30 while scanning without removing documents (20) from theoutput tray 150. - Another important characteristic is the stacking of the
documents 20 in theoutput tray 150. If thedocuments 20 are not laying flat, one on top of another, theprocessor 110 will stop the scanning process and preventadditional documents 20 from stacking improperly. Improper stacking may be an indication of the controlled output stacking 120 feature not operating properly or being inadvertently turned off. Based on theoutput tray 150 characteristics, proper adjustment of the outputtray side guides 160 orend stop 170 will be determined. The scanning may be stopped for the operator to adjust theside guides 160 orend stop 170, or an auto adjust feature can be employed to make the correction while scanning is continued. - Based on document information from an
input imaging device 40 the condition of thedocument 20 exiting thescanner 10 will be compared to condition ofdocuments 20 entering thescanner 10 to determine if damage to thedocument 20, such as bent or torn corners, is occurring within thedocument transport 70, as is shown inFIG. 2 . Theprocessor 110 will then stop the scanning process and alert the operator. - Using the information from the
input imaging device 40 the number ofdocuments 20 entering thedocument scanner 10 can be compared to the number ofdocuments 20 exiting thescanner 10. If the number ofdocuments 20 exiting thedocument scanner 10 does not match the number ofdocuments 20 entering thedocument scanner 10 the operator will be alerted to the lostdocument 20. - In a C-
shape document transport 70 thedocument 20 order can be tracked usingdocument 20 content captured by theoutput imaging device 140 in conjunction with the rearraster capture device 90. Indocument scanner 11, shown inFIG. 3 , having a straight throughdocument transport 70, thedocument 20 order can be tracked using thedocument 20 content captured by theoutput imaging device 140 in conjunction with the frontraster capture device 80. - In one embodiment of the invention, an image of a
document 20 in aninput tray 30 is captured with aninput imaging device 40 such as a raster capture device, CCD sensor, or CMOS sensor. The capturedinput tray image 190 is transmitted to animage processor 100 such as a microprocessor or a computer. The document is then transported through adocument scanner 10 which captures a raster scannedimage 180 of thedocument 20 and the raster scannedimage 180 is transmitted to theimage processor 100. Theimage processor 100 verifies the accuracy of the raster scannedimage 180 by comparing the raster scannedimage 180 of thedocument 20 to theinput tray image 190 of thedocument 20. If the raster scannedimage 180 of thedocument 20 does not match theinput tray image 190 of thedocument 20,scanner 10 functions may be modified or other corrective actions taken. Corrective actions may include rotation of the raster capture device, changing a color capture mode, or cleaning image optics. - The
input tray image 190 of thedocument 20 is captured as anarea image 210 rather than raster by raster as is typically used to capture the raster scannedimage 180 of thedocument 20. Theinput tray image 190 of thedocument 20 may be low resolution or high resolution. - In another embodiment of the invention, the
document 20 is moved to anoutput tray 150 for holdingdocuments 20 after it exits thescanner 10 and an image of thedocument 20 in theoutput tray 150 is captured with anoutput imaging device 140. The capturedoutput tray 150 image is transmitted to theimage processor 100 which verifies the accuracy of the raster scannedimage 180 by comparing the raster scannedimage 180 of thedocument 20 to theinput tray image 190 of thedocument 20 and theoutput tray image 200 of thedocument 20. - In yet another embodiment of the invention, an image of a
document 20 in aninput tray 30 for holdingdocuments 20 is captured as anarea image 210 rather than raster by raster with aninput imaging device 40. Capturing the image as anarea image 210 means that an image of theentire document 20 is taken rather than imaging thedocument 20 raster by raster, which is the usual way of scanning adocument 20. The capturedinput tray image 190 is transmitted to animage processor 100 and thedocument 20 is transported to anoutput tray 150. After thefirst document 20 has been transported out of theinput tray 30, an image of asecond document 20 in theinput tray 30 is captured and transmitted to theimage processor 100. - In a further embodiment, an image of the
document 20 in theoutput tray 150 is captured with anoutput imaging device 140 and transmitted to theimage processor 100. The accuracy of theinput tray 30 image is verified by comparing theinput tray image 190 of the document to theoutput tray image 200 of thedocument 20. - The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the scope of the invention.
