Description

  The present invention relates to a form order automatic correction system.

Conventionally, when a bundle of a plurality of forms is read as a continuous image, the image is acquired by a scanner having a continuous paper feed function, that is, a sheet feeder. At this time, the setting direction of the form on the sheet feeder is determined as a system, and the operator has consciously set a bundle of forms so that the direction is correct.
For this reason, when the form set on the sheet feeder is set in the reverse direction or the reverse direction, the image data in the wrong order is recognized. Therefore, in order to acquire correct image data, it is necessary to erase the erroneous image data after reading and then set it again in the correct orientation or face-up, and this is troublesome. there were.

  Here, in Patent Document 1, when the first page of the original is read and it is determined that the first page is blank, the read image data is rearranged in the reverse order and output, and the second page is blank. Describes a technique for determining that a double-sided original or a single-sided original is set correctly. Also, a technique for displaying the first page on the display unit and causing the operator to check whether or not it is the correct first page when reading a double-sided document, and outputting it if it is correct, and rearranging the order if it is different. Is disclosed.

JP2001-251383A

  However, according to the above-mentioned patent document 1, when reading a double-sided document, the front and back cannot be determined. Therefore, if the form set is wrong, it is determined whether the operator is on the correct first page before saving and outputting the read data. Must be confirmed. Even if it is not a double-sided original, if the side of the original that is white is dirty, it cannot be correctly recognized as a white paper, and the single-sided original is recognized as a double-sided original, and the single-sided original is read. Regardless, there is also a problem that extra time is required because a correctness check on the first page is required when reading a double-sided document.

  The present invention solves the problems of the conventional form reading system, and automatically corrects the form order that can acquire correct image data regardless of the direction of the form set and without requiring confirmation from the operator. The purpose is to provide a system.

  Therefore, in the form front / back discrimination method in the form order automatic correction system of the present invention, the image storage unit for storing the image data of the front and back sides of the form bundle acquired by the form reading device, and the image storage unit A form identification unit that determines which of the front and back image data of the form bundle is the actual surface, and a form identification in which the form identification unit stores form feature information for identifying the actual surface of the form bundle When the form feature information is recognized from the back side image data stored in the image storage unit in the information storage unit and the form identification unit, the back side image data stored in the image storage unit is the actual front side. The form bundle is corrected in the correct order by the form aligning unit that corrects the reverse side image data stored in the image storage unit in the reverse order.

  Further, in the form front / back discrimination method in another form order automatic correction system of the present invention, the form identifying unit recognizes form feature information from the front and back image data stored in the image storage unit, and the image storage unit When the position information of the form feature information stored in the form is compared with the position information of the form feature information stored in the form identification information storage unit, the position information of the form feature information stored in the form identification information storage unit is different The front and back surfaces stored in the image storage unit are identified such that the orientation of the form bundle is incorrect and the position information of the form feature information stored in the form identification information storage unit is matched in the form alignment unit. Correct by rotating the orientation of the image data.

  Further, in the form front / back discrimination method in another form order automatic correction system of the present invention, the form reading apparatus has a sheet feed mechanism and a double-sided reading mechanism, and can read a plurality of forms continuously. Use a scanner.

  According to the present invention, both image data on the front surface and the back surface are acquired by the scanner device, and from the form characteristic information, it is determined which image data on the front surface and the back surface is the actual surface by the form identification. When the image data is an actual surface, the image alignment order is reversed in the form alignment unit, so that correct image data can be acquired even when the form bundle is set upside down.

  Therefore, since the correct image data can be obtained regardless of how the form bundle is set up, down, up, down, left, and right, it is possible to eliminate re-reading due to the form set failure.

  In addition, since the front and back sides of the form are determined in advance using the form feature information, it is possible to efficiently perform the form reading process without requiring the operator to check whether the front and back sides of the form are correct or not when reading a double-sided document. be able to.

  FIG. 1 is a diagram showing a configuration of a form reading system according to an embodiment of the present invention.

  In the figure, a scanner device 10 has a scanner unit 101 having a function of continuously reading image data on the front and back surfaces of a plurality of forms and acquiring the image data of the form. In the present invention, the scanner device 10 is preferably an image scanner device provided with a sheet feed mechanism and a double-sided reading mechanism.

  The control device 20 is connected to the scanner device 10 and is a computer having a display function such as a display and an input function such as a keyboard, and controls the scanner device 10.

  The control device 20 has a control unit 201 having a function of controlling the entire system, a function of receiving an input instruction from an operator, an input unit 202 composed of input devices such as a keyboard and a mouse, and a display function for the operator. A display unit 203 configured by a display device such as a display, an image storage unit 204 having a function of storing image data acquired by the scanner unit 101 and image data for output, and a surface stored in the image storage unit 204 In addition, a form identification unit 205 having a function of performing rule identification using ruled line features as form feature information for the image data on the back side and a form identification unit 205 having a function of determining which is the actual front side. It has a function to store information related to forms to be performed, and pre-stores form feature information necessary for form identification such as ruled line features. The form identification information storage unit 206 has a function of rearranging the back side image data stored in the image storage unit 204 in the reverse order, that is, in the normal order when the back side image data is the actual front side of the form. The form arranging unit 207 is provided.

  The image storage unit 204 and the form identification information storage unit 206 are configured by storage means such as a memory or a hard disk. The form identifying unit 205 and the form arranging unit 207 are software, and are realized by a computer.

  FIG. 2 is a detailed configuration diagram of the image storage unit 204.

  In FIG. 2, an image storage unit 204 has a front surface image data area 204a for storing the image data of the front side of the form acquired by the scanner unit, a back side image data area 204b for storing the back side image data, and finally the output of this system. And 204c having a function of storing image data.

  Next, the basic flow of the form automatic correction system according to the first embodiment of the present invention will be described.

  FIG. 3 is a diagram showing an operation flow of the first embodiment, and FIGS. 4 to 6 are diagrams showing a display screen of the display unit 203 during operation of the control unit 20.

  The form in the present embodiment is composed of a form bundle consisting of a plurality of sheets. The forms constituting the form bundle are arranged in a predetermined order, and the front and back directions are aligned. Further, it is assumed that the ruled line feature of the form is registered in advance as the form feature information in the form identification information storage unit 206 so that at least the first form can be identified by the ruled line feature.

  S1: First, a form is read. The operator prepares a form bundle, sets the form bundle on the scanner unit 101, and issues a form reading instruction from the input unit 202. At this time, when setting the form in the scanner unit 101, the operator sets the form bundle on the sheet feeder without being aware of the front and back surfaces. The display unit 203 displays the contents of FIG. 4 and is updated to the display of FIG. 5 when the operator designates “1: read”.

  When the operator gives a reading instruction, the scanner unit 101 continuously scans the form and acquires image data of the form. Of the acquired image data, the part read as the front side is stored in the front side image data area 204a of the image storage unit 204 shown in FIG. 2, and the part read as the back side is stored in the back side image data area 204b.

  When the form bundle is correctly set and read, the actual front side of the form bundle is stored in the front image data area 204a, and the back side is stored in the back image data area 204b. If the front and back sides of the form bundle are erroneously set and read, the actual front side of the form bundle is placed in the back side image data area 204b, and the back side is placed in the front side image data area 204a. Stored in

  S2: Next, the front / back determination is performed for the first read form. The form identifying unit 205 refers to the image data stored in the front image data area 204a and the back image data area 204b of the image storage unit 204, and which of the front image data area 204a and the back image data area 204b is the actual front image. Determine if it is data.

  When the form bundle is correctly set, the first image data of the form bundle stored in the surface image data area 204a is the actual surface. Conversely, if the front and back sides of the form bundle are set incorrectly, the last image data of the form bundle stored in the back image data area 204b becomes the actual front side.

  The form identifying unit 205 identifies the first image data in the front surface image data area 204a and the last image data in the back surface image data area 204b, and is a form including ruled line features registered in the form identification information storage unit 206. The person who is present is determined as the actual surface.

  As a result of the front / back determination (S2), when the last image data of the form bundle stored in the back side image data area 204b is the actual front side, the form identifying unit 205 determines that the form order needs to be corrected, Shifts to form front / back correction processing (S3).

  If the first image data of the form bundle stored in the front image data area 204a is the actual front face, the form identifying unit 205 determines that the form order need not be corrected, and the form front / back correction process (S3) Is skipped and the process proceeds to the result output process (S4).

  S3: The form alignment unit 207 arranges the image data stored in the back image data area 204b in the reverse order, that is, in the normal order in the actual form bundle, and stores it again in the back image data area 204b.

S4: If the first image data stored in the surface image data area 204a is an actual surface, all the image data stored in the surface image data area 204a are stored in the output image data area 204c. If the last image data stored in the back side image data area 204b is the actual front side, all the data corrected in the above-mentioned form front / back correction process (S3) and stored again in the back side image data area 204b are stored. Are stored in the output image data area 204c. That is, the correctness of the set of form bundles is determined based on the front and back sides of the first form bundle.
Note that at this time, it is possible to set whether to acquire a double-sided image or only a single-sided image, and the method of storing in the output image data area 204c may be changed according to the setting. In the case of setting to acquire both sides, if one of the front surface image data area 204a and the back surface image data area 204b, which is determined to be the front surface, is output to the output image data area 204c alternately, a form is obtained. A continuous image arranged in the order of front and back from the first sheet of the bundle can be acquired. In the case of setting to acquire only one side, a continuous image of only the front surface can be obtained by outputting only the image determined to be the front surface.

  When the form order is corrected in the form front / back correction process (S3), the result output process (S4) may be performed by storing directly in the output image data area 204c without storing it in the back image data area 204b.

  When the image data is stored in the output image data area 204c, the display unit 203 is updated to the display of FIG. The operator designates “1: reading menu” when performing the next reading after evacuating the image data stored in the output image data area 204c to another storage location. To end reading, “2: End” is designated. When “1: reading menu” is designated, the display unit 203 is updated to the contents shown in FIG. 4, and the operator continues the reading operation.

  In this way, the form identifying unit 205 discriminates the front and back, and when the last image data stored in the back image area data 204b is the actual front, the image data is rearranged in the reverse order, that is, in the normal order. Thus, even when the front and back sides of the form are set incorrectly and the reading is executed, the correct image data is output, so that the operator does not have to execute the reading process again.

  In addition, since the front and back sides of the form are determined in advance using the form feature information, it is possible to efficiently perform the form reading process without requiring the operator to check whether the front and back sides of the form are correct or not when reading a double-sided document. be able to.

  In this embodiment, the ruled line feature is used as the form feature information. However, various identification methods such as identification by sheet ID can be adopted in addition to the identification by the ruled line feature.

Next, a second embodiment of the present invention will be described.
According to the second embodiment, it is also possible to correct the vertical and horizontal orientations of the form using the form feature information.

  Since the basic system configuration in the second embodiment is the same as that in FIGS. 1 and 2, the same reference numerals as those in FIGS. 1 and 2 are used and the description thereof is omitted.

  In the second embodiment, the form identifying unit 205 has a function of determining which one of the front image data area 204a and the back image data area 204b of the read image data has ruled line characteristics and the ruled lines of the image data. The form identification information storage unit 206 has a function of comparing the feature and the ruled line feature stored in the form identification information storage unit 206. The form identification information storage unit 206 uses the ruled line feature as the form feature information as shown in FIG. The ruled line feature of the image data is stored, and the image sorting unit 207 does not match the ruled line feature of the image data stored in the form identification information storage unit 206 with the image identifying unit 205 determining that the form identifying unit 205 has the ruled line feature. In this case, it differs from the first embodiment in that it has a form rotation function for correcting the direction by rotating the read image data by 90 degrees to the left or right.

  Hereinafter, the flow of the operation for automatically correcting the document direction will be described with reference to FIG.

  S11: As with S1 in the first embodiment, a form reading process is performed.

  S12: Next, direction determination is performed. In the form identification information storage unit 206, image data of a form including ruled line features as shown in FIG. 8, for example, is stored in advance as the correct form direction. Depending on whether the form identification unit 205 can acquire ruled line features from the image data of the front image data area 204a and the back image data area 204b stored in the image storage unit 204 after the form reading process (S11), the front image It is determined which of the data area 204a and the back image data area 204b is image data having a ruled line. In this embodiment, it is assumed that image data having ruled line features is stored in the surface image data area 204a.

  After determining image data having ruled line features from the image data in the front image data area 204a and the back image data area 204b, the ruled line characteristics stored in the form identification information storage unit 206 and the ruled lines read in the form reading process (S11) The ruled line features of image data having features are compared.

  If the ruled line feature of the image data read in the form reading process (S11) matches the ruled line feature of the correct image data stored in the form identification information storage unit 206, the image data rotation process (S13) is performed. ) Is skipped, and the image data stored in the surface image data area 204a is stored in the output image data area 204c.

  If the form identifying unit 205 determines that the image data of the form is read in the wrong direction as shown in FIG. 9, the process proceeds to image data rotation processing (S13).

  S13: The form aligning unit 207 rotates the image data in the wrong direction by 90 degrees to the left or right until the ruled line feature matches the image data of FIG. 8 stored in advance in the form identification information storage unit 206.

  For example, when the image data stored in the surface image data area 204a is form image data read by setting the form in the wrong direction as shown in FIG. 9, the image data stored in the surface image data area 204a is The image data of FIG. 9 is rotated until it matches with the ruled line feature of the image data stored in the form identification information storage unit 206 of FIG.

  When image data having a ruled line feature that has been read is rotated, the image data having no ruled line feature is also rotated. For example, when image data having ruled line features is rotated 90 degrees to the left, image data not having ruled line features can be rotated 90 degrees to the right so that the direction of the form bundle can be corrected correctly even in a double-sided document. it can. That is, in the process of rotating both sides, it is determined how to rotate the image data having no ruled line feature depending on how many times the image data having the ruled line characteristic is rotated to the left or right. Further, the rotation processing may be performed simultaneously on both sides by interlocking with the rotation of the image data. In this case, since the rotation of the back surface is completed when the rotation direction is determined, the output can be performed immediately.

  After the rotation processing, the image data stored in the surface image data area 204a matched with the image data for the correct form stored in the form identification information storage unit 206 is stored in the output data area 204c.

  S14: After storing in the output data area 204c, the same processing as S4 of the first embodiment is performed.

  As described above, the ruled line feature is determined from the image data of the form bundle read by the form identifying unit 205, and the ruled line feature of the image data and the ruled line of the image data for the correct form stored in the form identifying information storage unit 206 in advance. Compare the features, and if they do not match, rotate the image data in the correct direction in the form aligning unit 207 to obtain correct image data even if the top and bottom and left and right sides of the form bundle are set incorrectly Can do.

  In the second embodiment, description has been made by means of storing the ruled line feature of image data in the correct direction in advance in the form identification information storage unit 206. For example, the ruled line of image data in the wrong direction as shown in FIG. If the feature is stored in advance in the form identification information storage unit 206 and it is recognized that the image data upside down as shown in FIG. 9 has been read, the image data in the wrong direction in advance is rotated, for example, by rotating the image data 180 degrees. Information such as how many times the image data of the form is rotated to the left and right may be stored in association with each other for each ruled line feature of the image data in the wrong direction. In this case, it is possible to determine how to rotate the image data of the read form without performing the image data rotation process until it matches the ruled line feature stored in the form identification information storage unit 206. Only one processing and rotation process is required.

  The second embodiment can be performed in combination with the first embodiment. In this case, either the order correction or the direction correction may be performed first, and both processes may be performed simultaneously in the form identifying unit 205 and the form arranging unit 207.

  Therefore, since the correct image data can be obtained regardless of how the form bundle is set up, down, up, down, left, and right, it is possible to eliminate re-reading due to the form set failure.

The present invention relates to a system for acquiring a form image with a scanner device, such as a filing system for form images.
