It is connected to the device 180. That is, when the lesson management apparatus 180 is to be used via the image processing apparatus 100, the lesson support processing apparatus 130 mediates between them. Specifically, the image processing apparatus 100 scans paper documents such as answer sheets (including test sheets and reports) and attendance slips, and the class support processing apparatus 130 registers the images in the class management apparatus 180. Examples of the image processing apparatus 100 include a copying machine, a facsimile machine, a scanner, and a multifunction machine (an image processing apparatus having any two or more functions such as a scanner, a printer, a copying machine, and a facsimile machine). As the class management device 180, a so-called learning support system (LMS: Learning Management System) or the like is applicable.
Further, the class support processing device 130 may perform image processing. In other words, image processing is performed on the image of the document received from the image processing apparatus 100, a list of the results of the image processing is generated, and the result of the image processing according to the successful completion of the image processing itself. Is stored in the lesson management device 180, and after the result of the image processing is stored, the correction result is stored in the lesson management device 180 when the user corrects the list of results by the image processing. To reflect the result of the image processing.

In particular, character recognition processing may be performed as an example of image processing. For example, the class support processing device 130 is not merely an intermediary between the image processing device 100 and the class management device 180 but recognizes characters of an image (scanned image such as an answer sheet) received from the image processing device 100, and according to the result. The storage location in the class management device 180 may be varied. For example, for each student (an example of a person who has written an answer sheet), a folder is set in the lesson management apparatus 180, and the student can browse documents in the folder. After the scoring answer sheet is scanned by the image processing apparatus 100, the class support processing apparatus 130 character-recognizes the student ID number (an example of a character for identifying the person who wrote the answer sheet) in the answer sheet, You may make it store the score of a scanned image, an answer sheet, etc. in the folder corresponding to the student ID number in the class management device 180. That is, in this case, the document data storage destination and the data stored in association with the storage destination are extracted by the character recognition process. As another example, it may be a case of determining a distribution destination folder according to a result of image recognition of a document. Also, the score (which is an example of a scoring result, also referred to as a score) written on the answer sheet is recognized, and the average score is calculated, sorted, etc., and presented as a list to the teacher who performed the scoring You may do it.

The image processing apparatus 100 includes an authentication module 105, a class support service operation module 110, a print module 115, and a scan module 120. The image processing apparatus 100 is connected to the DB 125, and is also connected to a class support processing apparatus 130, a teacher terminal apparatus 170, and a class management apparatus 180 via a communication line 198.
The authentication module 105 is connected to the class support service operation module 110. The authentication module 105 authenticates a user who uses the image processing apparatus 100. For example, authentication may be performed by reading data (such as a user ID) in an IC card, allowing a user to input a user ID and a password, or authenticating by inputting a user's biometric information. May be.

The class support service operation module 110 is connected to the authentication module 105, the print module 115, the scan module 120, and the class support processing device 130. The class support service operation module 110 accepts a user operation for using the class management apparatus 180. For example, a user's operation for allowing the lesson management device 180 to store an image of the graded answer sheet scanned by the scan module 120 is accepted.
The print module 115 is connected to the class support service operation module 110. The print module 115 prints the document data received from the teacher terminal device 170.

  The scan module 120 is connected to the class support service operation module 110. The scan module 120 scans a document and generates an image of the document. The document here is a paper document (however, it is not necessarily paper and may be a sheet of resin or the like), for example, a scored answer sheet or the like. “Students who wrote the answer sheet” correspond to students who took the test. Moreover, the teacher who is a grader corresponds to “the person who scored the answer sheet”. The scanned document image is passed to the character recognition module 152 of the class support processing device 130.

  The DB 125 is connected to the image processing apparatus 100. The DB 125 stores data necessary for processing of the image processing apparatus 100. For example, there are an image of a document scanned by the scan module 120, document data printed by the print module 115, and the like.

The lesson support processing device 130 includes an account linkage module 135, a teacher information acquisition module 140, a total scan module 145, an image processing module 150, and a lesson management device registration module 160. The class support processing device 130 is connected to the class support service operation module 110 and the DB 165 of the image processing device 100, and is connected to the image processing device 100, the teacher terminal device 170, and the class management device 180 via the communication line 198. It is connected.
The account linkage module 135 is connected to the teacher information acquisition module 140. The account cooperation module 135 links the user of the image processing apparatus 100 and the user of the lesson management apparatus 180. For example, a user who has logged in with the image processing apparatus 100 may confirm whether or not the user has been registered with the lesson management apparatus 180 and log in to the lesson management apparatus 180. It is to be noted that whether or not it is registered in the lesson management apparatus 180 is obtained by logging in the data acquired from the lesson management apparatus 180 by the teacher information acquisition module 140 (data relating to account data of the lesson management apparatus 180) and the image processing apparatus 100. This is done by collating user data. In addition, by linking accounts between the image processing apparatus 100 and the lesson management apparatus 180, the lesson management apparatus 180 can be used via the lesson support processing apparatus 130 by operations on the image processing apparatus 100. It becomes like this.
The teacher information acquisition module 140 is connected to the account cooperation module 135 and the user management module 185 of the class management device 180. The teacher information acquisition module 140 acquires data related to the account data of the lesson management apparatus 180 from the lesson management apparatus 180 and passes it to the account cooperation module 135.

The total scan module 145 is connected to the image processing module 150 and the class management device registration module 160. The total scan module 145 generates a list of character recognition results by the character recognition module 152. For example, the total scan module 145 may generate a list in which the scoring results are associated with the person who wrote the answer sheet that is the character recognition result of the character recognition module 152.
The total scan module 145 may perform statistical processing using the character recognition result by the character recognition module 152. For example, the aggregation scan module 145 may perform statistical processing on the character recognition result of the scoring result. Statistical processing includes, for example, calculation of average points, aggregation processing, extraction of highest and lowest points, calculation of standard deviation, sorting, and the like. Moreover, you may make it determine pass / fail.

The image processing module 150 includes a character recognition module 152, a correction instruction receiving module 154, and a correction processing module 156, and is connected to the total scan module 145. The image processing module 150 performs processing (character recognition, correction processing, etc.) on an image of a document scanned by the scan module 120 of the image processing apparatus 100.
The character recognition module 152 performs character recognition on the image of the document scanned by the scan module 120 of the image processing apparatus 100. For character recognition, an existing character recognition technology (in particular, handwritten character recognition) may be used. It may be an answer sheet after scoring as a document. In this case, the character recognition module 152 character-recognizes a character (for example, a student ID number) and a scoring result (for example, a score) that identify the person who wrote the answer sheet. For example, the position of the area where the student ID number and the score are described is determined in advance, and an image is extracted from the area to perform character recognition.

  The correction instruction receiving module 154 receives a correction to the character recognition result by the teacher 172. For example, the character recognition result by the character recognition module 152 is transmitted to the teacher terminal device 170. The teacher terminal device 170 presents the teacher 172 with at least a part of an image (an image subjected to character recognition) of the document that is a character recognition target and a character recognition result of the image. Specifically, transmission by e-mail, browsing on a web page, and the like are applicable. For example, a student ID number image and its character recognition result, a score image and its character recognition result are presented. The teacher 172 confirms them and performs a correction operation on the character recognition result. The correction instruction receiving module 154 receives the correction operation. For example, there are a student ID number correction operation and a score correction operation.

  When the teacher 172 corrects the character recognition result, the correction processing module 156 reflects the correction result by the correction in the character recognition result stored in the lesson management device 180. That is, since the lesson support processing device 130 is an intermediary device between the image processing device 100 and the lesson management device 180, the character recognition result is stored in the lesson management device 180. Note that not only the final (corrected) character recognition result but also the character recognition result before correction is stored in the lesson management device 180. On the other hand, since character recognition is performed by the lesson support processing device 130 (character recognition module 152), the correction operation of the teacher 172 is received and correction is performed. This is to correct the character recognition program, the recognition dictionary, etc. in order to improve the character recognition rate in the future.

  The correction processing module 156 may transmit an instruction for correcting the scoring result in the lesson management apparatus 180 to the lesson management apparatus 180 when the character recognition result of the scoring result is corrected. This is because the scoring result already stored in the lesson management device 180 needs to be corrected. Since the score is stored in the storage location (folder, URL: Uniform Resource Locator, etc.) prepared for each student ID number by the lesson management device registration module 160, the score in the storage location corresponding to the student ID number may be changed. .

  In addition, the correction processing module 156, when the character recognition result of the character (for example, student ID number) identifying the person is corrected, the correction processing module 156 in the storage location of the person before the correction in the class management device 180. The scoring result may be deleted, and the scoring result may be stored in the storage location of the person after the correction. As described above, since storage locations are prepared for each student ID number, correcting the student ID number also changes the storage location in the class management device 180. Therefore, the score is stored in the storage location of the student ID number before correction (incorrect student ID number). Therefore, the score in the storage location of the student ID number before correction is deleted, and the score is stored in the storage location of the corrected student ID number (correct student ID number).

  Further, when correction is made on the character recognition result of the character for identifying the person, the correction processing module 156 further displays “an answer after scoring” in the storage place of the person before correction in the class management device 180. The “image of the form” may be deleted, and the “image of the answer sheet after scoring” may be stored in the storage location of the person in the class management apparatus 180 after the correction. As will be described later, “an image of the answer sheet after scoring” may be stored in the storage location for each student ID number together with the above-mentioned score. In this case, in the same way as the score, delete the `` image of the answer sheet after scoring '' in the storage location of the student ID before correction, and put `` image of the answer paper after scoring '' in the storage location of the student ID after correction Do memorize.

The class management device registration module 160 is connected to the total scan module 145 and the content management module 190 of the class management device 180. The class management device registration module 160 stores the character recognition result by the character recognition module 152 in the class management device 180. The class management device registration module 160 stores the scoring results in a storage location for each person who has written the answer sheet in the class management device 180. For example, the score is stored in a storage location prepared for each student ID number.
Further, the lesson management apparatus registration module 160 may further store “an image of the answer sheet after scoring” in the storage location for each person who has written the answer sheet in the lesson management apparatus 180. Therefore, the student can view the answer sheet and the scoring result.

  The DB 165 is connected to the class support processing device 130. The DB 165 stores data necessary for processing by the class support processing device 130. For example, there are an image of a document that is a character recognition target by the class support processing device 130, a character recognition result, a correction instruction, and the like.

The class management device 180 has a user management module 185 and a content management module 190. The lesson management device 180 has a function as a learning support system, is connected to the DB 195, and is connected to the image processing device 100, the lesson support processing device 130, the teacher terminal device 170 via the communication line 198. It is connected.
The user management module 185 is connected to the content management module 190 and the teacher information acquisition module 140 of the class support processing device 130. The user management module 185 manages the account of the lesson management device 180. For example, it manages accounts for teachers 172 and students. For example, when the teacher 172 logs in from the teacher terminal device 170 via the communication line 198 or is shared with the account of the image processing device 100, the image processing device 100 is mediated by the class support processing device 130. Is permitted to use the class management device 180.

  The content management module 190 is connected to the user management module 185 and the class management device registration module 160 of the class support processing device 130. The content management module 190 manages content used for classes. For example, the content includes an image of the answer sheet after scoring received from the lesson support processing apparatus 130, the score of the answer sheet, and the like. After the reflection processing by the correction processing module 156 of the lesson support processing device 130 is performed, the content management module 190 gives the person who wrote the answer sheet a character recognition result (specifically, a score) and an answer sheet after scoring. Allow viewing of images. Before the reflection process is performed, browsing is not permitted. Note that the “reflecting process” may include a confirmation process by the teacher 172 (an operation indicating that correction is necessary for a modification and that confirmation is completed for a modification that is not necessary). Therefore, the correction is not performed as “after the reflection process is performed”, but the confirmation process is performed as a browsing target.

  The DB 195 is connected to the class management device 180. The DB 195 stores data necessary for processing by the lesson management apparatus 180. For example, there are a scoring result received from the class support processing device 130, an image of an answer sheet after scoring, user information, and the like.

The teacher terminal device 170 is used by the teacher 172, and uses the image processing device 100, the lesson support processing device 130, and the lesson management device 180 via the communication line 198. For example, an image that is a character recognition target in the document and a character recognition result of the image are received from the class support processing device 130 and presented to the teacher 172. Then, the correction operation by the teacher 172 for the character recognition result is accepted, and a correction instruction is transmitted to the class support processing device 130. For example, as a character recognition result, there are a student ID number and a score, and the teacher 172 compares the original image (the image in the column where the student ID number and score are written) with the student ID number and score, and the correction is made. When necessary (when the character recognition result is incorrect), a correction operation is performed.
Further, the image processing apparatus 100 and the class support processing apparatus 130, and the class support processing apparatus 130 and the class management apparatus 180 may communicate with each other via a communication line 198, or may be connected by a USB (Universal Serial Bus) or the like.

Are connected to each other. The communication line 198 may be wireless, wired, or a combination thereof, and may be, for example, the Internet or an intranet as a communication infrastructure. The functions of the class support processing device 130 and the class management device 180 may be realized as a cloud service.
The authentication server 250 authenticates the teacher 172 and the student 272 with the image processing apparatus 100, the class support processing apparatus 130, the class management apparatus 180, and the like. Further, authentication cooperation (so-called single sign-on) may be performed.

For example, the class support processing device 130 performs the following processing. In particular, this explanation (in the present paragraph number and the explanation in the next paragraph number) is intended to facilitate understanding of the present embodiment, and is intended to be limitedly interpreted using this explanation. Not done. And it should not be judged that the invention to be patented is described in the detailed explanation of the invention (Patent Act Article 36 (6) (i)) using only this explanation part. It is natural.
First, the lesson support processing apparatus 130 that does not employ this embodiment will be described.
The class support processing device 130 scans paper documents such as tests, reports, and attendance slips, and registers them in the class management device 180. By simply scanning the graded answer sheet with the image processing device 100, it is possible to perform batch registration into the class management device 180, reducing the effort of the teachers involved in creating the student score list, and speedy feedback Contributes to improving motivation.
The class support processing device 130 reads the student ID number and the score that are handwritten in a predetermined entry field by the character recognition processing, and registers the PDF and score for each student in the class management device 180. At this time, the data registered in the lesson management device 180 is temporarily stored in the reserved area. Note that the information in the reserved area is not permitted to be viewed by the student 272. Then, a student total score list in which the student ID number, the score, the processing result, and the like are described and a summary result file that summarizes the PDFs of all students are created, and the teacher 172 is notified by email as the processing result.
The teacher 172 confirms the contents of the student-specific score list. If there is an error in the character recognition result, the teacher 172 corrects the student-specific score list and accesses the lesson management device 180 to manually correct the contents.
In character recognition processing, characters may be recognized incorrectly. Even if the read information is incorrect, the character recognition process itself ends normally. Therefore, even if no error has occurred, the processing result must be visually confirmed.
If the “student ID number” and “student ID number (image)” are compared and are not read correctly, there is a possibility that data is registered for the wrong student. It is necessary to access the lesson management device 180 to delete incorrect student data and re-register with the correct student.
When “score” and “score (image)” are compared and not correctly read, it is necessary to access the lesson management device 180 and correct the score information.
When all the content confirmation is completed and a confirmation operation is performed on the lesson management device 180, the data stored in the reserved area is stored in the public area and is disclosed to the student 272.
The teacher 172 checks the contents of the student score list, and if there is an error in the processing content, the teacher 172 needs to correct the student score list and access the class management device 180 to manually correct the score list. There is a high possibility that it will be troublesome twice and human error will occur.
In order to solve the above problem, there is a method of displaying the same content as the student score list on the web of the class management device 180 and confirming and correcting the content, but all the class management devices 180 need to cope with it. Therefore, the cost is high. That is, since processing by the lesson management device 180 is necessary, it is difficult to handle all of the plurality of types of lesson management devices 180. That is, the lesson management device 180 is manufactured and sold by a plurality of companies and is not compatible, and the specification of the lesson management device 180 may be different for each school.

(2) Conduct the test. That is, the student 272 writes the answer on the answer sheet. At that time, the student ID number will be written on the answer sheet.
(3) Teacher 172 scores each answer sheet. At that time, the score is written on the answer sheet.
(4) The image processing apparatus 100 scans the answer sheet after scoring.
(5) The class support processing device 130 performs character recognition on the scanned image and creates a score list. Then, the scanned image and the character recognition result are stored for each student in the class management device 180.
(6) The teacher terminal device 170 acquires a scan image and a score list from the class support processing device 130 and displays them in accordance with the operation of the teacher 172.
(7) The teacher 172 performs an operation of correcting the student ID number and the score as the character recognition result.
(8) The class support processing device 130 corrects the character recognition result in the class management device 180 according to the correction operation.
(9) After the correction is completed, the student 272 is allowed to view his / her own scanned image (answer sheet image) and score. For example, the student 272 is notified by e-mail or the like that the scoring has been completed and that it can be viewed.
(10) The student terminal device 270 acquires a scanned image (an answer sheet image) and a score of the student 272 from the lesson management device 180 according to the operation of the student 272, and displays it. The student 272 can know the scoring results.
