Description

  The present invention relates to a form processing system, a form processing method, and a program.

  2. Description of the Related Art A document processing system that uses a scanner to convert image data handled by a financial institution or the like into image data, recognizes character information described in the document using OCR (optical character recognition), and imports the information into a computer is popular. In this type of form processing system, for example, character information is recognized by OCR after the form identification unit identifies the form pattern. The character information includes, for example, money amount information (transfer amount, etc.). When using OCR, it is ideal that all character information described in the form is automatically captured, but in practice, it often happens that the character information cannot be recognized by OCR. The necessary character information is given to the form processing system by the manual input operation (see, for example, Patent Document 1 below).

  In addition, in financial institutions and the like, generally, a plurality of forms are collected into units called batches, and amount information matching processing (also referred to as scrutiny) is performed for each batch. That is, for example, when a batch is composed of 1000 sheets, the amount information of 1000 sheets is loaded into the system using OCR and using manual input as necessary. The system calculates the total amount information, and compares the calculated total amount information with reference total amount information regarded as a true value. If they match, the verification process for the batch is completed.

  FIG. 7 shows a functional block diagram of the main control unit 210 and the storage unit 250. The main control unit 210 includes functional blocks referred to by reference numerals 211 to 219, that is, an image data reception unit 211, a pattern identification unit 212, an OCR processing unit 213, an entry unit 214, a collation unit 215, and a search condition setting unit 216. A search processing unit 217, a display control unit 218, and a correction history information generation unit 219. The functions of the image data receiving unit 211, the pattern identifying unit 212, the OCR processing unit 213, the entry unit 214, the matching unit 215, the search condition setting unit 216, the search processing unit 217, the display control unit 218, and the correction history information generation unit 219 are as follows: Image data reception program, pattern identification program, OCR processing program, entry program, verification program, search condition setting program, search processing program, display stored in memory (not shown) in main control unit 210 or storage unit 250, respectively The control program and the correction history information generation program are realized by a CPU (Central Processing Unit; not shown) in the main control unit 210 reading out and executing the program read out by the CPU. The storage unit 250 includes an image data storage unit 251, a pattern identification result storage unit 252, a character information storage unit 253, a related information storage unit 254, a correction history information storage unit 255, and a pattern dictionary storage unit 256. Each of the storage units 251 to 256 may be understood to be a part of the storage area in the storage unit 250. Actually, each functional part other than that shown in FIG. 7 is provided in the main control unit 210, and each storage unit other than that shown in FIG. 7 is provided in the storage unit 250.

  The image data receiving unit 211 receives the image data of each form and each header card acquired by the scanner unit 113 from the form processing apparatus control unit 116. The image data storage unit 251 stores the image data received by the image data receiving unit 211. Hereinafter, the forms and header cards that are targets of batch processing are also referred to as target forms and target header cards, respectively. The significance of batch processing will be described later. The form and header card whose image data has been acquired by the scanner unit 113 and stored in the image data storage unit 251 are subjected to batch processing.

  The pattern identification unit 212 performs pattern identification processing for identifying the pattern of the target form or the target header card based on the stored contents of the pattern dictionary storage unit 256 and the image data stored in the image data storage unit 251. The pattern identification unit 212 performs pattern identification processing for each target form and for each target header card. Pattern information indicating the identification result of the pattern identification unit 212 is stored in the pattern identification result storage unit 252.

  A method for identifying the pattern of the target form using the contents stored in the pattern dictionary storage unit 256 will be described. The pattern dictionary storage unit 256 stores feature information of a plurality of different registered patterns. The feature information of a certain registered pattern is formed by the feature amount of the registered pattern sufficient to distinguish the registered pattern from other registered patterns. Specifically, each registered pattern includes shape information indicating the shape of paper as a form (including information on the size of the paper), and ruled line information indicating what kind of ruled line is written on the form. The shape information and ruled line information are included in the feature information. The plurality of registered patterns define the shape information and ruled line information of actual plural types of forms. For example, as shown in FIG. 8, it can be considered that a pattern dictionary DICp storing the shape information and ruled line information of each of the first to Kth registered patterns is stored in the pattern storage unit 256 (K is 2 or more). integer). The pattern identification unit 212 extracts shape information and ruled line information of the target form from the image data of the target form of interest, and compares the extracted shape information and ruled line information with the shape information and ruled line information of each registered pattern in the pattern dictionary DICp. By doing so, the pattern of the target form is identified (that is, which of the first to Kth registered patterns is matched). A similar method can be applied to the target header card, and the pattern of the target header card is also identified. However, here, for simplification of explanation, there is only one type of pattern of the target header card, and it is always a common header card pattern (thus, it is always identified as a common header card pattern). ). Here, it is assumed that the pattern dictionary DICp is stored in the pattern dictionary storage unit 256 in the storage unit 250, but the pattern dictionary storage unit 256 may be provided in the pattern identification unit 212. .

  The form processing device control unit 116 may receive the identification result of the pattern identification unit 212 and control which stacker of the stacker unit 115 discharges each target form based on the identification result ( The same applies to the target header card). As a result, the same type of form can be accumulated in a common stacker. Alternatively, the pattern identification unit 212 may be provided in the form processing apparatus control unit 116. Further alternatively, sorting data for specifying which stacker of the stacker unit 115 to discharge each target form may be given to the form processing apparatus control unit 116 in advance.

  The OCR processing unit 213 executes OCR processing for recognizing and acquiring character information of the target form or target header card from the image data stored in the image data storage unit 251. The OCR process is performed for each target form and for each target header card. As a method for recognizing character information in the OCR process, a known recognition method classified as optical character recognition can be used. The character information recognized by the OCR processing unit 213 includes numerical information indicating a monetary amount (hereinafter sometimes referred to as OCR monetary information) and character information other than the monetary amount (hereinafter referred to as non-monetary information). By OCR processing, arbitrary character information other than the amount information described in the target form or the target header card can be recognized and acquired as information other than the amount.

  The OCR amount information of a certain target form and target header card was obtained by optical character recognition, respectively, for the amount information described in the actual form of the target form and target header card (hereinafter sometimes referred to as true amount information). Is. Therefore, ideally, the OCR amount information always coincides with the true amount information, but the two may differ due to various factors (for example, the former may be 10,000 yen and the latter may be 1000 yen). .

  Actually, when the OCR processing unit 213 recognizes and acquires the character information of a certain target form, the OCR processing unit 213 determines which part of the target form based on the pattern identification result of the target form by the pattern identification unit 212. It is determined whether there is amount information and information other than the amount, and the determination result is used to recognize and acquire the amount information (OCR amount information) and the information other than the amount. The same applies to the target header card.

  In the OCR process, the OCR processing unit 213 can output an OCR reliability indicating the probability of the result of the OCR process. Here, as an example, the OCR reliability takes values from 1 to 100, and the closer to 100, the more probable the OCR processing result is. The derivation of the OCR reliability can also be performed by a known technique. When the OCR reliability for a certain target form is higher than a predetermined lower limit reliability (for example, 30), the OCR processing unit 213 determines that character information (especially money amount information) can be recognized, and associates it with the target form. When a “correct reading signal” is output and the OCR reliability for a certain target form is equal to or lower than a predetermined lower limit reliability, it is determined that character information (particularly monetary amount information) cannot be recognized, and associated with the target form “ "Unread signal" is output. The same applies to the target header card. In addition, although OCR reliability can be produced | generated and output for every character, OCR reliability in this embodiment shall point out OCR reliability with respect to OCR amount information.

  The entry unit 214 receives input of character information (amount information or information other than the amount) via the input unit 240 in association with the entry target. Either the target form or the target header card can be an entry target. Typically, for example, a target form or target header card to which an unread signal is output is an entry target. Since the character information is not completely obtained or only partially obtained by the OCR processing for the entry target for which the unread signal is output, the operator enters the character information of the entry target in the input unit 240. Enter. The entry unit 214 stores character information input via the input unit 240 in the storage unit 250 in association with the entry target. The expression that certain information is input to the input unit 240 is synonymous with the expression that the information is input to a functional block (for example, the entry unit 214) in the main control unit 210 via the input unit 240.

  The amount information input via the input unit 240 is particularly referred to as manually input amount information. The character information storage unit 253 (FIG. 7) stores character information for each target form and for each target header card. The character information stored here includes OCR amount information or manually input amount information, and information other than the amount acquired by the OCR process or input via the input unit 240. The related information storage unit 254 stores related information (described later) that is information other than image data and other than character information for each target form and for each target header card.

  Referring to FIG. 9, the storage unit 250 stores image data, pattern information, character information, and related information in association with each other for each target form and for each target header card. That is, the image data, pattern information, character information, and related information about the first target form are stored in the storage unit 250 in a state of being associated with each other, and the image data, pattern information, character information about the second target form are stored. And the related information are stored in the storage unit 250 in a state of being associated with each other. The same applies to each target form other than the first and second target forms, and the same applies to each target header card. Hereinafter, a set of information composed of image data, pattern information, character information, and related information associated with the i-th target form and stored in the storage unit 250 is referred to as set information SJ [i] (i is an integer). .

  The image data in the set information SJ [i] is image data of the i-th target form. The amount information in the character information in the set information SJ [i] is the OCR amount information acquired by the OCR process for the i-th target form or the manually input amount input via the input unit 240 for the i-th target form. Information. Information other than the amount in the character information in the set information SJ [i] is information other than the amount acquired by the OCR process for the i-th target form or the amount input via the input unit 240 for the i-th target form. Information. In the following description, in order to avoid confusion with the amount information (that is, true amount information) described in the actual item of the i-th target form, the amount information (i.e., set information SJ) of the i-th target form stored in the storage unit 250. The amount information in the character information in [i]) may be particularly referred to as stored amount information. The pattern information in the set information SJ [i] indicates the identification result of the pattern identification unit 212 for the i-th target form pattern, that is, the i-th target form.

  The related information includes a batch number and an ID number. The batch number in the set information SJ [i] is a unique number of the batch to which the target form corresponding to the set information SJ [i] belongs. The ID number of the set information SJ [i] is a unique serial number assigned to the i-th target form.

  The related information further includes an OCR reliability and an OCR read flag. The OCR reliability in the set information SJ [i] is the OCR reliability output by the OCR processing unit 213 for the i-th target form. The OCR reading flag in the set information SJ [i] is a flag indicating whether or not a correct reading signal is output for the i-th target form. Here, as an example, “1” is assigned to the OCR reading flag when a correct reading signal is output, and “0” is assigned to the OCR reading flag when an unread signal is output. .

  The related information further includes an SOCR flag and a manual input flag. The SOCR flag and the manual input flag indicate whether or not character information (may be interpreted as only monetary information) is created using the entry unit 214, and the presence or absence of image data. Specifically, character information (may be interpreted as only monetary information) in the set information SJ [i] is created using the entry unit 214 (in other words, the character information is input to the input unit 240). And the set information SJ [i] includes image data of the i-th target form, “1” is assigned to the SOCR flag and “0” is assigned to the manual input flag. On the other hand, character information (may be interpreted as only monetary information) in the set information SJ [i] is created using the entry unit 214 (in other words, the character information is obtained by input to the input unit 240). If the set information SJ [i] does not include the image data of the i-th target form, “0” is assigned to the SOCR flag and “1” is assigned to the manual input flag. When character information (may be interpreted as only monetary information) in the set information SJ [i] is created by OCR processing without using the entry unit 214, the SOCR flag and manual input in the set information SJ [i] “0” is assigned to both of the flags (in this case, naturally, the set information SJ [i] includes the image data of the i-th target form).

  For example, there may be a group of forms that are stapled in a certain batch, or a form that is torn or the like and cannot be read by the scanner unit 113 or is difficult. For such a form, the operator may give up reading an image by the scanner unit 113 and input character information for the form by manual input using the input unit 240 and the entry unit 214 from the beginning. “1” is assigned to the manual input flag only for such a form, and “0” is assigned to the manual input flag for other forms. Although there is no image data for a form in which “1” is substituted for the manual input flag, such a form may be included in the batch processing target. However, in the following, it is assumed that image data is acquired and stored for all target forms unless otherwise specified.

  As shown in FIG. 10, set information including image data, pattern information, character information, and related information is generated and stored in the storage unit 250 for the target header card as well as the target form.

  Referring to FIG. 7 again, for each batch, the collation unit 215 compares the predetermined reference total amount information with the calculated total amount information based on the stored amount information of all target forms belonging to the batch. A collation process (proof process) is performed to determine whether or not the The verification unit 215 outputs a verification OK signal when the reference total amount information and the calculated total amount information match, and outputs a verification NG signal when they do not match.

  The reference total amount information for a certain batch indicates the sum of the true amount information described in the actual items of all target forms belonging to the batch (the amount information is regarded as the true value of the total). Typically, the reference total amount information is amount information recognized by the main control unit 210 with respect to the target header card, and details including modifications and the like will be described later. The calculated total amount information for a certain batch indicates the sum of the stored amount information of all target forms belonging to the batch. The stored amount information (that is, the OCR amount information or the manually input amount information) of a certain target form ideally always matches the amount information (that is, the true amount information) described in the actual target form. Due to various factors, the two may not match. As a result, it is often necessary for the operator to make corrections using the entry unit 214 until the collation 215 signal is output from the collation unit 215 and the collation is OK (that is, until the collation OK signal is output). However, many batches (for example, 1000 sheets) are often included in one batch, and the operator finds and corrects a form derived from the verification NG signal from many forms without any clue. It takes a lot of work.

  The search condition setting unit 216 sets a search condition that is useful for searching for a form from which a verification NG signal is derived in order to reduce such trouble. In other words, the search condition setting unit 216, for a certain batch, in order to match the calculated total amount information with the reference total amount information, from among the stored amount information of all target forms belonging to the batch stored in the storage unit 250 Then, a condition is set for searching for a stored amount information candidate that needs to be corrected (a stored amount information candidate to be corrected). Here, the candidate is also referred to as correction candidate amount information, and the set condition is also referred to as a search condition. Then, the search processing unit 217 performs a search process for actually searching the stored amount information as the correction candidate amount information in accordance with the search condition set by the search condition setting unit 216. That is, for example, in the search process, storage amount information satisfying the set search condition is searched as correction candidate amount information from the storage amount information of all target forms belonging to the batch stored in the storage unit 250. What has been searched here is considered to be more likely to require correction using the entry unit 214 than those that are not. Therefore, by using the search condition setting unit 216 and the search processing unit 217, it is possible to reduce time and effort for deriving collation OK. Details of the search condition will be described later.

  The display control unit 218 controls display contents on the display unit 230. The correction history information generation unit 219 generates correction history information that can be used for the above-described search, and the correction history information storage unit 255 stores the correction history information. The content of the correction history information will be described later.

<< Batch processing flow >>
The flow of batch processing will be described with reference to FIG. FIG. 11 is a flowchart of batch processing. A batch process consists of the process of step S11-S20, and is performed for every batch. For the sake of concreteness and clarification of the explanation, one focused batch in which batch processing is performed is referred to as the current batch, and the target header card belonging to the current batch is referred to by the symbol HED. The first to m-th target forms to which it belongs are referred to by symbols T [1] to T [m]. m is the number of target forms belonging to the current batch.

  First, in step S11, images of the target header card HED and the target forms T [1] to T [m] are acquired by the scanner unit 113, and each image data representing each acquired image is controlled by the form processing apparatus. The image data is stored in the image data storage unit 251 through the unit 116 and the image data receiving unit 211. In subsequent step S12, the pattern identification unit 212 performs pattern identification processing based on the image data of the target header card HED and the target forms T [1] to T [m], and the target header card HED and the target form T [1] to Each pattern of T [m] is identified.

  In step S13, the OCR process based on the image data of the target header card HED and the target forms T [1] to T [m] is performed using the identification result of the pattern identification process. 1] to T [m], the character information of the target header card HED and the target forms T [1] to T [m] is recognized and acquired. The acquired character information is stored in the character information storage unit 253 as described above.

  That is, for example, when a correct reading signal is output for the target form T [1], and therefore the amount information of the target form T [1] is recognized by the OCR processing, the OCR amount that is the recognized amount information. The information is stored as amount information in the set information SJ [1] of the target form T [1] (that is, the amount information stored in the set information SJ [1]). The same applies to target forms other than the target form T [1], and the same applies to the target header card HED.

  In step S14 following step S13, the main control unit 210 determines whether or not an unread signal is output in the OCR process. When the correct reading signal is output in all of the OCR processes for the target header card HED and the target forms T [1] to T [m] (N in Step S14), the process proceeds from Step S14 to Step S16. If any unread signal is output (Y in step S14), the process proceeds from step S14 to step S15.

  In step S15, unread entry work is performed by the operator. Of the target header card HED and the target forms T [1] to T [m], the one to which an unread signal is output is the target of entry. Since the character information is not obtained completely or only partially obtained by the OCR process for the entry object for which the unread signal is output, the operator selects the entry object via the input unit 240. Input character information.

  That is, for example, when an unread signal is output for the target form T [2] and the amount information of the target form T [2] cannot be recognized by the OCR process (that is, when the OCR amount information cannot be acquired). In step S15, the operator performs an unread entry operation for inputting the amount information of the target form T [2] to the input unit 240. The manually input amount information, which is the amount information input here, is received by the entry unit 214 and stored as amount information in the set information SJ [2] of the target form T [2] (that is, the set information SJ [ 2] stored amount information). At this time, “1” is assigned to the SOCR flag in the set information SJ [2] of the target form T [2]. Further, when an unread entry operation is performed on the target form T [2], the display control unit 218 reads out the image data of the target form T [2] from the image data storage unit 251, and the target form T [2]. 2] may be displayed on the display unit 230, which facilitates unread entry work. Although the unread entry work has been described by taking the target form T [2] as an example, the same applies to target forms other than the target form T [2], and the same applies to the target header card HED. The same is true even if the character information not obtained by the OCR process is information other than the amount of money.

  The unread entry entry operation in step S15 is performed for all of the target header card HED and target forms T [1] to T [m] for which the unread signal is output, and the unread signal is output. When the unread entry work is completed for all the items that have been processed, the process proceeds to step S16. At the stage of reaching step S16, set information SJ [1] to SJ [m] of the target forms T [1] to T [m] as shown in FIG. 9 is stored in the storage unit 250 (251 to 254). It becomes the state. Similarly, the set information of the target header card HED is also stored in the storage unit 250 (251 to 254). In addition, it may be considered that storage control to the storage unit 250 including control for storing each set information in the storage unit 250 is performed by a storage control unit (not shown) included in the main control unit 210. .

  In the stage from step S14 or S15 to step S16, if the storage amount information in the set information SJ [i] is recognized by the OCR process, the storage amount information in the set information SJ [i] is the OCR amount. Information (i is an integer). On the other hand, if the stored amount information in the set information SJ [i] is not recognized by the OCR process and is obtained through the input to the input unit 240 in the unread entry work, the set information SJ The stored amount information in [i] is manually input amount information. Typically, for example, in the current batch, there are a plurality of target forms whose OCR amount information is stored amount information, and there are a plurality of target forms whose manual amount information is stored amount information.

In step S16, the collation unit 215 derives the calculated total amount information CAL _SUM for the current batch. The calculated total amount information CAL _SUM indicates the sum of the stored amount information of the target forms T [1] to T [m]. For example, when m = 1000, each stored amount information of the target forms T [1] to T [800] is OCR amount information, and each stored amount information in the target forms T [801] to T [1000] If it is manually input amount information, a total of 800 pieces of OCR amount information that is storage amount information of the target forms T [1] to T [800], and storage amount information of the target forms T [801] to T [1000]. Total amount information including a total of 200 manually input amount information is derived as calculated total amount information CAL _SUM . After the calculation total amount information CAL _SUM is derived, the process proceeds to step S17.

In step S <b> 17, the collation unit 215 performs collation processing for determining whether or not the calculated total amount information CAL _SUM matches the reference total amount information REF _SUM . The reference total amount information REF _SUM indicates the total of the true amount information described in the actual items of the target forms T [1] to T [m] belonging to the current batch. As assumed in FIG. 11, when the target header card HED is included in the current batch, the reference total amount information REF _SUM is storage amount information of the target header card HED in the storage unit 250. The storage amount information of the target header card HED in the storage unit 250 is the OCR amount information included in the result of the OCR processing for the target header card HED, or the manually input amount input in the unread entry work for the target header card HED. Information. The amount information described in the actual item of the target header card HED is regarded as the true value of the sum of the true amount information described in the actual items of the target forms T [1] to T [m].

The reference total amount information REF _SUM may be transmitted from the server device SV to the control device 200. In that case, the collation unit 215 performs collation processing using the reference total amount information REF _SUM received from the server device SV. Or, for example, the reference total amount information REF _SUM is not described in the target header card HED, or the target header card HED itself does not exist, and the reference total amount information REF _SUM is described in any paper medium or any It may be stored in a recording medium (semiconductor memory or the like). In that case, the operator inputs the reference total amount information REF _SUM described or stored in the paper medium or the recording medium to the input unit 240, and the collation unit 215 stores the input reference total amount information REF _SUM . To perform collation processing.

If the calculated total amount information CAL _SUM matches the reference total amount information REF _SUM in the verification process in step S17, a verification OK signal is output from the verification unit 215 and the batch processing for the current batch is completed. If the information CAL _SUM does not match the reference total amount information REF _SUM , a verification NG signal is output from the verification unit 215, and after performing the verification NG notification in step S18 and the search condition setting image in step S19, Proceed to step S20. In addition, regarding the current batch, when the number of target forms should be m, only information on target forms for less than m sheets is obtained, or information on target forms exceeding m sheets is obtained. In this case, a verification NG signal is output, but here, it is assumed that such a situation has not occurred.

The verification NG notification is a predetermined notification for notifying the operator that the calculated total amount information CAL _SUM does not match the reference total amount information REF _SUM, and is provided by a notification unit (not shown) provided in the control device 200. Realized. The verification NG notification may be any notification appealing to the five senses of the operator, but usually includes display of a predetermined verification NG notification image on the display unit 230 as shown in FIG. In this case, the notification unit can be considered to be realized by the display control unit 218 or by the display control unit 218 and the display unit 230. In addition, the verification NG notification may include a predetermined sound output. In FIG. 12, for the sake of simplification, a state in which only the verification NG notification image is displayed on the display unit 230 is shown, but the verification NG notification image may be another arbitrary image (for example, a search condition setting image). ) May be displayed.

  When the verification NG signal is output, one or more of the stored amount information of the target forms T [1] to T [m] in the storage unit 250 is different from the amount information (that is, the actual amount information) described in the actual product. Therefore, there is storage amount information that needs to be corrected in order to eliminate the difference. In order to eliminate the difference efficiently, it is useful to search for a candidate for storage amount information that needs to be corrected, and a condition for searching for the candidate (that is, correction candidate amount information) is the search condition setting unit 216. The search condition to be set. The search condition setting image displayed in step S19 is an image for accepting the setting of the search condition.

  The search condition setting image is displayed on the display unit 230 under the control of the display control unit 218. Hereinafter, when simply displaying, it means displaying on the display unit 230. The display control unit 218 may display the search condition setting image based only on the output of the verification NG signal from the verification unit 215 even if no operation is applied to the input unit 240. Alternatively, when a predetermined operation is input to the input unit 240 after the verification NG notification is performed (for example, when a predetermined key operation is input to the keyboard forming the input unit 240), the display control unit The search condition setting image 218 may be displayed. A detailed description of the search condition setting image will be provided later.

  In step S20, a correction entry operation for actually correcting the stored amount information that needs correction is performed by the operator. For example, when the storage amount information of the target form T [1] is different from the true amount information of the target form T [1], the storage amount information of the target form T [1] is storage amount information that needs to be corrected. Thus, the target form T [1] becomes an entry target. At this time, the operator performs a correction entry operation for inputting the true amount information of the target form T [1] to the input unit 240. The manually input amount information, which is the amount information input here, is received by the entry unit 214 and is overwritten and stored as the stored amount information of the target form T [1] (that is, the stored amount in the set information SJ [1]). Information is corrected to manually entered amount information by correction entry work). The entry unit 214 receives the input of the true amount information of the target form T [1] via the input unit 240 as the input of the correction instruction, and corrects the stored amount information of the target form T [1] according to the correction instruction. Functions as a means. When a correction entry operation is performed on the target form T [1], the display control unit 218 reads the image data of the target form T [1] from the image data storage unit 251, and the target form T [1]. These images may be displayed on the display unit 230, which facilitates the correction entry work. Although the correction entry work has been described by taking the target form T [1] as an example, the same applies to target forms other than the target form T [1].

After the correction entry work, the process returns to step S16, and the derivation process in step S16 and the collation process in step S17 are performed again. The calculated total amount information CAL _SUM derived in step S16 through the correction entry work is the sum of the storage amount information of the target forms T [1] to T [m] after being corrected by the correction entry work. The number of stored amount information corrected by the correction entry work is 1 or more and m or less. A series of processes consisting of steps S16 to S20 is repeated until the calculated total amount information CAL _SUM derived through the correction entry operation matches the reference total amount information REF _SUM. The batch processing for the current batch is finished.

  The batch process as described above can be performed for each batch.

<< Display contents and search process >>
FIG. 13 shows an example of display contents of the display unit 230 under the control of the display control unit 218. In FIG. 13, information on a plurality of batches based on the storage contents of the storage unit 250 is displayed in a matrix. The display content shown in FIG. 13 is only a schematic example, and can be variously modified.

  In FIG. 13, information about the first batch is displayed in a plurality of rows 501, information about the second batch is displayed in a plurality of rows 502, and information about the third batch is displayed in a plurality of rows 503. . In the first to third batches, information about the target header card is displayed in the hatched lines. In FIG. 13, information based on information other than the amount stored in the storage unit 250 is displayed in a plurality of columns 520. Here, as an example, the information displayed based on the information other than the amount includes the name of the branch that received the target form or the target header card, the corresponding branch name code, the storage destination of the amount indicated by the target form, and the corresponding storage The destination code, the category of the target form and the corresponding category code, the type of the target form and the corresponding type code, and the year in which the target form is handled and the corresponding year code are included, and items indicating these are included A plurality of columns 520 are listed for each target form and for each target header card (however, only the branch name for the target header card). The information displayed in the plurality of columns 520 regarding each target form may include information obtained from the character information of the target header card, or information provided to the main control unit 210 via the input unit 240 separately. May also be included.

  In the column 530, the number information is displayed. Specifically, in the column 530, the number information (corresponding to 22 in FIG. 5) stored in the storage unit 250 for the target header card is displayed for each target header card. Although the target form may be composed of a set of a plurality of sheets, in the present embodiment, it is considered that the target forms are independent one by one. For this reason, it is assumed that the number information of the target forms shown in the column 530 is all 1. In the column 540, the amount information stored in the storage unit 250 for the target header card is displayed for each target header card, and the amount information stored in the storage unit 250 for the target form is displayed for each target form.

  In a plurality of columns 550, information based on related information stored in the storage unit 250 is displayed. Here, as an example, the information displayed based on the related information includes the input classification based on the OCR reading flag and / or the SOCR flag, and the serial number based on the ID encryption, and there are a plurality of items indicating them. Column 550 is listed for each target form and for each target header card.

  FIG. 14 shows a display example of the display unit 230 when the search condition setting image 600 is displayed. For example, when the display of FIG. 13 is performed using the entire display area of the display unit 230, when a verification NG signal is output or a predetermined operation is input to the input unit 240 (for example, the input unit When a predetermined key operation is input to the keyboard forming 240, the search condition setting image 600 is displayed in a pop-up (superimposed display) in a partial area below the display unit 230.

  15, for convenience of illustration, only the search condition setting image 600 shown in FIG. 14 is shown mainly enlarged in the vertical direction. The search condition setting image 600 includes a search icon 611 with a character “search” and a cancel icon 612 with a character “cancel”. When the operator inputs an operation for designating the cancel icon 612 to the input unit 240 (clicks on the icon 612), the search condition setting image 600 is not displayed.

  When the search condition setting image 600 is displayed, the search condition setting unit 216 may set a search condition (a condition for searching for correction candidate amount information) according to the input operation content to the input unit 240 by the operator. The search processing unit 217 can search for the amount information satisfying the set search condition as the correction candidate amount information from the stored amount information of the target forms T [1] to T [m] belonging to the current batch. . Then, the display control unit 218 can cause the display unit 230 to display the stored amount information as the searched correction candidate amount information.

  The search condition setting image 600 includes, as characteristic items, a digit / overflow search item 620, a designated number search item 630, and a correction history search item 640. In addition, the search condition setting image 600 includes search items 651 to 657 and search items 661 to 663, which will be described later, and how to use the items 620, 630, and 640, and Operations and the like will be described in the main control unit 210 corresponding to these items. The search condition setting image 600 may be displayed at an arbitrary timing. However, in the following, the target header card HED and the target forms T [1] to T [m] unless otherwise specified. A method for using the search condition setting image 600 will be described on the assumption that a verification NG signal is output for the current batch consisting of and the correction entry operation in step S20 is performed.

[Rounding / overflow search operation]
An explanation will be given of the digit / overflow search item 620 (hereinafter sometimes simply referred to as the item 620). The item 620 includes the manually entered amount information included in the stored amount information of the target forms T [1] to T [m] in the searched amount information group, and there is a possibility that the amount of money in the searched amount information group is incorrect. This is an item for retrieving certain amount information as correction candidate amount information. The digit error in the amount of money is the amount of money between the stored amount information (here, manually entered amount information) and the amount information (ie, the true amount information) described in the actual form of the target form corresponding to the stored amount information. It is a difference of digits. Specifically, for example, 10 times or 1/10 times the stored amount information (here, manually input amount information) is the amount information (that is, the actual amount information) described in the actual form of the target form corresponding to the stored amount information. When they match, the stored amount information includes a digit error. That is, for example, the true amount information of the target form T [1] is “10000 yen”, while the manually input amount information as the stored amount information of the target form T [1] is “1000 yen” or “100,000 yen”. In some cases, the manually entered amount information as the stored amount information of the target form T [1] has a digit error.

  The digit / overflow search item 620 includes small items 620 [0] to 620 [3]. In a state in which an operation for designating the small item 620 [0] is input to the input unit 240, the search process for searching for the amount information with the possibility of a digit error as the correction candidate amount information is not executed. The sub-items 620 [1], 620 [2], and 620 [3] are items for searching for one, two, or three correction candidate amount information that may have a digit error. When an operation for specifying the sub-item 620 [p] is input to the input unit 240 (where p is 1, 2 or 3), an operation for specifying the search icon 611 is input to the input unit 240 (this) (Referred to as a click on the search icon 611), and the main control unit 210 (mainly 216 and 217) performs a digit / overflow search operation for searching at least p pieces of correction candidate amount information that may have a digit error. Done. In the carry / overflow search operation, the search condition setting unit 216 includes the manually entered money amount information included in the stored money amount information of the target forms T [1] to T [m] in the searched money amount information group. A search condition is set so that money amount information with a possibility of a digit error in the money amount is searched as correction candidate money amount information, and the search processing unit 217 searches for money amount information that satisfies the search condition. A search process for actually searching from the amount information group is executed. In other words, according to the search condition, the stored amount information with the possibility of an incorrect digit in the amount is searched from the group of searched amount information as the correction candidate amount information.

With reference to FIGS. 16A to 16C, a specific example in which there is only one digit error is shown. Assume that m = 5 and the true amount information of the target forms T [1] to T [5] is all “10000 yen”. In this case, the reference total amount information REF _SUM (hereinafter sometimes abbreviated as amount information REF _SUM ) is “50000 yen”. Furthermore, among the stored amount information of the target forms T [1] to T [5], at least the stored amount information of the target form T [2] is included in the searched amount information group, and the target forms T [1] and It is assumed that all the stored amount information of T [3] to T [5] is “10000 yen”. However, in the first case shown in FIG. 16B, the storage amount information of the target form T [2] is “100,000 yen”, and as a result, the calculated total amount information CAL _SUM (hereinafter abbreviated as amount information CAL _SUM ). Is 144,000 yen). On the other hand, in the second case shown in FIG. 16C, the storage amount information of the target form T [2] is “1000 yen”, and as a result, the amount information CAL _SUM is “41000 yen”. Assume. In the first and second cases, the stored amount information of the target form T [2] has a digit error.

FIG. 17 is a flowchart of the carry / overflow search operation. When a carry / overflow search operation is performed in a state where the small item 620 [p] is specified (where p is 1, 2 or 3), the search processing unit 217 displays the difference (REF _SUM -CAL _SUM ) Is derived (step S31), and then the amount A is derived by dividing the difference (REF _SUM -CAL _SUM ) by (p × 9) (step S32), and then the amount A is multiplied by 10 to obtain the amount B Is derived (step S33). That is, “A = (REF _SUM −CAL _SUM ) / (p × 9)” and “B = A × 10”. If the difference (REF _SUM −CAL _SUM ) is positive, the stored amount information matching the amount A is searched as correction candidate amount information from the searched amount information group, and the difference (REF _SUM −CAL _SUM ) is negative. If so, stored amount information that matches the absolute value of the amount B (hereinafter referred to as amount | B |) is searched from the group of searched amount information as correction candidate amount information. In this way, in the carry / overflow search operation, the correction candidate amount information is searched based on the difference (REF _SUM −CAL _SUM ). When the difference (REF _SUM −CAL _SUM ) is positive, the derivation of the amount B (step S33) can be omitted.

  In the first case of FIG. 16B, since p = 1, the difference is “−90000 yen”, the amount A is “−10000 yen”, the amount B is “−100,000 yen”, and the difference is negative. Therefore, the storage amount information of “100,000 yen” (that is, the storage amount information of the target form T [2]) is retrieved as the correction candidate amount information. In the second case of FIG. 16C, since p = 1, the difference is “9000 yen”, the amount A is “1000 yen”, the amount B is “100,000 yen”, and the difference is positive, so “1000” The stored amount information of “Yen” (that is, the stored amount information of the target form T [2]) is retrieved as the correction candidate amount information.

More specifically, when the difference (REF _SUM −CAL _SUM ) is positive, there are p ′ pieces of stored amount information that matches the amount A in the searched amount information group (p ′ is p The integers above), the p ′ pieces of stored amount information are determined to satisfy the search condition, and are searched as correction candidate amount information. That is, p or more stored amount information that matches the amount A is retrieved as the correction candidate amount information. If more than p stored amount information matches the amount A, there should be no digit error in the amount in some of them, but any stored amount that matches the amount A at the search stage Since there is an error in the amount of money in the information and it is unclear which storage amount information has no amount of money in the amount of money, all the stored amount information that matches the amount of money A is searched as correction candidate amount information. Similarly, when the difference amount (REF _SUM −CAL _SUM ) is negative and there are p ′ pieces of stored amount information matching the amount | B | in the searched amount information group, the p ′ The stored amount information is determined to satisfy the search condition, and is searched as correction candidate amount information.

However, when the difference (REF _SUM −CAL _SUM ) is positive, only when there are p pieces of stored amount information matching the amount A in the searched amount information group, the p number The stored amount information may be determined to satisfy the search condition and searched as correction candidate amount information. Similarly, when the difference amount (REF _SUM −CAL _SUM ) is negative, only when there are only p pieces of stored amount information matching the amount | B | The p pieces of stored amount information may be determined to satisfy the search condition and searched as correction candidate amount information.

When the difference (REF _SUM −CAL _SUM ) is positive, there is no stored amount information that matches the amount A in the searched amount information group, or the stored amount information that matches the amount A is p. When there are less than the number, it is determined that there is no storage amount information that satisfies the search condition, and the correction candidate amount information is not searched, and that fact is displayed on the display unit 230. Similarly, when the difference (REF _SUM −CAL _SUM ) is negative, there is no stored amount information that matches the amount | B | in the searched amount information group, or the amount | B | If there is less than p stored amount information, it is determined that there is no stored amount information that satisfies the search condition, and the correction candidate amount information is not searched, and that fact is displayed on the display unit 230.

  The sub-items 620 [1] to 620 [3] are used to specify how many correction candidate amount information that may have an error in the amount of digits or how many or more are to be searched in the carry / overflow search operation. Used for. That is, the small items 620 [1] to 620 [3] are used to specify the value of p. A value of 4 or more may be designated as the value of p.

  When one or more correction candidate amount information is searched, the display control unit 218 causes the display unit 230 to display the search result image. When the correction candidate amount information is not searched (that is, when there is no stored amount information satisfying the search condition), this is displayed on the display unit 230.

  An image 700 in FIG. 18 is an example of a search result image. The search result image 700 includes a search hit item 710. In the search hit item 710, information based on the set information of the target form having the correction candidate amount information as the stored amount information is displayed. In the example of FIG. 18, character information (including at least storage amount information 711 and further including a branch name) and related information in the set information of the target form having the correction candidate amount information as the storage amount information includes the search hit item 710. Included in

  When an operation for designating the search hit item 710 is input to the input unit 240, the display control unit 218 reads the image data of the target form corresponding to the search hit item 710 from the storage unit 250, and as shown in FIG. Based on the image data, an image 750 of the target form is displayed on the display unit 230. At this time, the image 750 may be displayed together with the search hit item 710. If the operator looks at the image 750 and determines that the correction candidate amount information (in the example of FIG. 19, the stored amount information 711 described as “100,000 yen” in the search hit item 710) should be corrected. For example, the corrected amount information is input to the storage amount information 711 field in the search hit item 710 through the input unit 240. In response to this input, the entry unit 214 corrects the stored content of the storage unit 250 so that the correction candidate amount information (stored amount information 711) is replaced with the corrected amount information. Thereby, the correction entry operation for one correction candidate amount information is completed.

  When a plurality of correction candidate amount information is searched, a plurality of search hit items 710 corresponding to the plurality of correction candidate amount information are included in the search result image. An image 702 in FIG. 20 is an example of a search result image including the search hit items 710 [1] and 710 [2] as two search hit items 710. When an operation for designating the search hit item 710 [i] is input to the input unit 240 (where i is 1 or 2), the display control unit 218 displays the image of the target form corresponding to the search hit item 710 [i]. The data is read from the storage unit 250, and the image of the target form is displayed on the display unit 230 based on the image data as in the case shown in FIG. It is determined whether the amount information should be corrected, and if it should be corrected, the corrected amount information is input through the input unit 240 in the storage amount information 711 [i] column of the search hit item 710 [i]. In response to this input, the entry unit 214 corrects the stored content of the storage unit 250 so that the correction candidate amount information (stored amount information 711 [i]) is replaced with the corrected amount information. Such an operation is performed for each of the search hit items 710 [1] and 710 [2]. The same applies when there are three or more correction candidate amount information.

  When manually entering monetary information, due to an incorrect keypad press on the keyboard, an extra “0” is added to the end of the monetary information (this is called overflowing), or “0” is missing at the end of the monetary information. (This is called a digit loss). Every day, an operator who performs a large amount of manual input operations at high speed generally assigns “00” or “000” to one key. Occurs. Further, when the “0” key is pressed at a high speed, too many or too few keystrokes of “0” may cause a digit overflow or a digit loss. By carrying out the carry / overflow search operation through the designation of the carry-over / overflow search item 620, it is possible to easily find correction candidate amount information with a possibility of overflow or carry-over and improve the efficiency of the correction entry work. It is possible to raise.

  Note that the work that is likely to cause a digit loss or overflow is unread entry work (S15 in FIG. 11) in which entry work is successively performed for a large amount of unread OCR, and correction entry work (FIG. 11). In step S20), it can be considered that digit loss or overflow is unlikely to occur. This is because in the correction entry work, it is considered that manual input is performed while confirming individual image data more firmly than in the unread entry work. Therefore, input to the input unit 240 in the unread entry operation of step S15 in the stored amount information of the target forms T [1] to T [m] in the searched amount information group in the digit / overflow search operation. However, the amount information input to the input unit 240 in the correction entry operation in step S20 may not be included. In addition, the OCR amount information in the stored amount information of the target forms T [1] to T [m] is not included in the searched amount information group in the digit / overflow search operation. It may be included.

[Start / end numerical value search operation]
The designated numeral search item 630 in FIG. 15 (hereinafter sometimes simply referred to as the item 630) will be described. An item 630 is an item for searching for correction candidate amount information based on the first numerical value or the last numerical value in the amount information. More specifically, the item 630 includes the OCR amount information included in the stored amount information of the target forms T [1] to T [m] in the searched amount information group, and includes “ This is an item for retrieving money amount information having a leading numerical value of “4” or money amount information having a trailing numerical value of “1” as correction candidate money amount information. The first numerical value is literally the first numerical value indicating the amount of money (“5” if it is 52658 yen), and is the numerical value of the highest part. The numerical value at the end is literally the numerical value at the end of the numerical value indicating the amount (“8” if it is 52658 yen), and is the numerical value of the first place. As shown in FIG. 15, the designated number search item 630 includes small items 631 and 632.

  When the search icon 611 is clicked in a state where an operation for specifying the small item 631 is input to the input unit 240, the main numerical value search operation is performed by the main control unit 210 (mainly 216 and 217). In the first numerical value search operation, the search condition setting unit 216 includes the OCR amount information included in the stored amount information of the target forms T [1] to T [m] in the searched amount information group and includes the searched amount information group. Then, the search condition is set so that the money amount information having “4” as the first numerical value is searched as the correction candidate money amount information (in other words, the search condition that the first numerical value of the money amount information is “4” is set). The search processing unit 217 executes a search process for actually searching for money amount information satisfying the search conditions from the searched money amount information group. That is, according to the search condition, based on the first numerical value of each stored amount information included in the searched amount information group, the stored amount information having “4” as the first numerical value from the searched amount information group is actually corrected candidate amount. Search as information.

  FIG. 21A shows an example of a form in which a yen mark (¥) and a numerical value indicating the amount are written by hand in the amount entry column (illustration of descriptions other than the amount entry column is omitted). In the OCR process for a certain form, based on the pattern identification result by the pattern identifying unit 212, it is determined which part of the form has an amount entry column in which the amount information is described, and color dropout or the like is used. The amount information described in the amount entry field is read while removing the amount entry field from the image data of the form (for example, the amount entry field is described in red and the amount information is described in black) Color dropout to remove red).

  In the amount entry column, a yen mark (¥), which is a prefix of the amount, is often written before the beginning of the numerical value indicating the amount. This yen mark (¥) is “4” in the OCR process. It is known that there is a high possibility of misrecognition (misrecognition by OCR processing is also referred to as misreading). In particular, as shown in FIG. 21 (a), if a break-up character of a yen mark that is often used by a bank clerk is written in a form that protrudes up and down in the amount entry column, the OCR process will change the break-up character of the yen mark. The possibility of misrecognizing “4” increases. FIG. 21B shows an image when the OCR processing unit 213 attempts to read the amount information through color dropout or the like, and the yen mark (¥) has a shape similar to “4”. Yes. When such misrecognition occurs in the target form T [i], the OCR amount information having the first value “4” for the target form T [i] is stored in the storage unit 250. Thus, the amount information of the target form T [i] is retrieved as the correction candidate amount information.

  On the other hand, when the search icon 611 is clicked in a state where an operation for designating the small item 632 (see FIG. 15) is input to the input unit 240, the main control unit 210 (mainly 216 and 217) performs the end numerical value search operation. Is called. In the trailing numerical value search operation, the search condition setting unit 216 includes the OCR amount information included in the stored amount information of the target forms T [1] to T [m] in the searched amount information group, and includes the searched amount information group. Then, the search condition is set so that the money amount information having “1” as the end value is searched as the correction candidate amount information (in other words, the search condition that the end value of the amount information is “1” is set). The search processing unit 217 executes a search process for actually searching for money amount information satisfying the search conditions from the amount information to be searched. That is, according to the search condition, based on the end value of each stored amount information included in the searched amount information group, the stored amount information having “1” as the end value from the searched amount information group is actually corrected candidate amount. Search as information.

FIG. 22A shows an example of a form in which a yen mark (¥) and a numerical value indicating the amount are written by printing or the like in the amount entry column (illustration of descriptions other than the amount entry column is omitted). Although not limited to the form shown in FIG. 22 (a), in the amount entry column of the form, the numerical value indicating the amount is written on the left side as the part with the larger place, and written on the right side as the part with the lower place. Further, for example, the amount entry column is ¹⁰⁷ to ⁰ of the value (or 10 ⁸ to 10 ^0-position value) multiple is also often configured to include a mass to be written. In the form shown in FIG. 22 (a), the right end of the amount entry column, that is, the right end of the square in which the first digit of the amount is to be written is thicker than the other boxes. This may be for the purpose of making the end of the amount entry column easily visible to the user of the form, etc., but in any case, the amount entry column as shown in FIG. Many forms are available.

  Then, for example, when the amount entry field of the form shown in FIG. 22 (a) is red, even if a numerical value indicating the amount is written in the amount entry field with black ink, the right end of the amount entry field removes red. May remain after a color dropout. Some black inks have strong redness and some are weak depending on the ink components. In addition, the red at the right end of the amount entry column may be red with a strong black component. Color dropout for the amount entry field is performed to separate the amount entry field and the value in the amount entry field and extract only the latter, but the color and darkness of the numbers in the amount entry field and the amount entry field, etc. Depending on, the separation may not be possible. FIG. 22B shows a form image after color dropout or the like when this separation is not sufficient, and shows that the right end of the amount entry column remains as a vertical line. .

  Even if the right end of the amount entry field remains as a vertical line, it is relatively easy to determine that the vertical line is not a numerical value if an area that is not read (area that is not recognized as a numerical value) is set appropriately in the form. Easy. However, there are many cases where the value in the monetary amount entry column deviates from the ideal position (the center position of each square) due to misalignment of the print. The right end of the column may be misrecognized as “1” as the first digit of the amount (FIG. 21B shows the state when 10000 yen is misrecognized as 100001 yen, but printing ), The first place may be replaced with “1” and mistakenly recognized as 10001 yen). When such misrecognition occurs in the target form T [i], the OCR amount information having the end value of “1” for the target form T [i] is stored in the storage unit 250, so that the end value search operation is performed. Thus, the amount information of the target form T [i] is retrieved as the correction candidate amount information.

  When the search icon 611 is clicked in a state where an operation for specifying both of the small items 631 and 632 (see FIG. 15) is input to the input unit 240, the main control unit 210 performs a leading numerical value search operation and a trailing numerical value search. The operations may be performed simultaneously. That is, the amount information having “4” as the first numerical value and the amount information having “1” as the last numerical value may be collectively searched as the correction candidate amount information from the searched amount information group.

  When one or more correction candidate amount information is searched for by the first numerical value search operation and the last numerical value search operation, the display control unit 218 displays a search result image including the searched correction candidate amount information (image 700, in the example of FIG. 18). In the example of FIG. 20, the image 702) is displayed on the display unit 230. The contents of the search result image, the operator's work performed after the search result image is displayed, and the operation of the control device 200 are the same as those described above. When the correction candidate amount information is not searched (that is, when the correction candidate amount information does not exist), in other words, when the storage amount information that satisfies the search condition does not exist, that fact is displayed on the display unit 230.

  Easily find correction candidate amount information that has the possibility of misreading the yen mark (¥) and misreading the right end of the amount entry column by the first numerical value search operation and the final numerical value search operation through the designation of the designated number search item 630 This makes it possible to improve the efficiency of correction entry work. In particular, for example, with regard to forms related to public charges, the same type of form is often handled in a certain period (for example, one month), and there is one form in a collection of the same type of form handled in large quantities. When misreading occurs, it is highly likely that the same misreading occurs for other forms. If the misreading that occurs for a collection of the same type of form is a misreading for the yen mark (¥) or a misreading for the right end of the amount entry column, the initial numerical value search operation and the final numerical value search operation can improve the efficiency of the correction entry work. Go up greatly.

  Note that the first numerical value search operation or the final numerical value search operation functions beneficially for the amount information acquired by the OCR process. The manually entered money amount information in the stored money amount information of the target forms T [1] to T [m] is not included, but may be included as a modification.

[Revision history search operation]
The correction history search item 640 in FIG. 15 (hereinafter sometimes simply referred to as the item 640) will be described. An item 640 is an item for searching for correction candidate amount information based on the correction history information.

  The correction history information will be described. The correction history information generation unit 219 (see FIG. 7) performs a correction history generation process for generating correction history information for the jth batch after the end of the batch process in which the jth batch is the current batch (j Is an integer representing the batch number).

  In the correction history generation process, the correction history information generation unit 219 determines whether or not the target form is a corrected form for each target form constituting the jth batch. The corrected form refers to a target form in which the stored amount information is corrected by the correction entry work in the process until the correct reading signal is output in the OCR processing but before the verification OK signal is output. Therefore, although the OCR amount information is obtained for the i-th target form constituting the j-th batch, the stored amount information of the i-th target form is corrected by the correction entry work until the collation OK signal is output. If it is, the i-th target form is determined to be a corrected form. After the OCR amount information was obtained for the i-th target form constituting the j-th batch, the stored amount information of the i-th target form was not corrected by the correction entry work in the process until the verification OK signal was output. In this case, it is determined that the i-th target form is not a corrected form. When the OCR amount information is not originally obtained for the i-th target form constituting the j-th batch, it is determined that the i-th target form is not a corrected form.

  The correction history information generation unit 219 reads the pattern of each corrected form belonging to the jth batch from the pattern information (see FIG. 9) stored in the storage unit 250. As described above, the pattern information of a certain target form indicates the pattern of the target form (that is, the identification result of the pattern identifying unit 212 for the target form). Therefore, the pattern of the corrected form is the pattern of the target form (any of the first to Kth registered patterns: refer to FIG. 8) indicated by the pattern information of the target form that is determined to be the corrected form.

  The revision history information generation unit 219 generates revision history information SRJ [j] for the jth batch as shown in FIG. 23, stores the revision history information SRJ [j] in the revision history information storage unit 255, and the jth batch. The correction history generation process for is completed. The revision history information SRJ [j] for the jth batch includes the revision number SK [j, 1] for the first registration pattern, the revision number SK [j, 2] for the second registration pattern, and the Kth registration. The correction number SK [j, K] for the pattern is included. Here, the number of corrections SK [j, k] is the number of correction forms having the kth registered pattern among the correction forms belonging to the jth batch (k is an integer satisfying “1 ≦ k ≦ K”). ). Therefore, for example, in the batch processing of the j-th batch, the OCR amount information was obtained for 10 target forms having the k-th registered pattern. However, the correction entry work in the process until the verification OK signal is output. If the storage amount information (OCR amount information) of the 10 target forms is corrected, “SK [j, k] = 10”.

  In the correction entry work, the entry unit 214 functions as a correction unit that accepts the input of the true amount information of the target form via the input unit 240 as an input of the correction instruction, and corrects the stored amount information of the target form according to the correction instruction. . The history of receiving the correction instruction until the verification OK signal is output is stored as the correction history information in a state in which the history is associated with the pattern of the target form corresponding to the corrected amount information.

  The form processing system can sequentially execute the batch processing described with reference to FIG. 11 a plurality of times. However, in the batch processing for the current batch, the correction candidate amount information can be searched using the reference correction history information. . The reference correction history information includes correction history information for batch processing completed in the past as viewed from the batch processing for the current batch.

  Here, from the viewpoint of the batch processing for the current batch, it is considered that the correction history information for the batch processing performed from (n-1) times to the previous time is included in the reference correction history information for the current batch (n is An integer of 2 or more). That is, for example, if the batch processing for the current batch is considered to be the n-th batch processing (batch processing for the n-th batch), the correction history information for the first to (n-1) -th batch processing is It is included in the reference correction history information for the current batch. Actually, when a batch process for the current batch is performed, a period that is a past period and has a predetermined time length (for example, a time length of 3 months) is set as a reference period, and is referred to The correction history information for batch processing performed during the period is included in the reference correction history information. In this case, the value of n can vary from day to day. However, the value of n may be fixed, or may be variably set based on an input of a predetermined operation on the input unit 240. Further, the length of the reference period may be variably set based on an input of a predetermined operation on the input unit 240.

  The search operation for the correction candidate amount information using the correction history information will be specifically described. For the sake of concrete explanation, it is assumed that the current batch is the nth batch. Then, as viewed from the batch process for the current batch, the batch processes performed before (n−1) times to 1 time before are the first to 1st processes performed on the first to (n−1) batches, respectively. This is the (n-1) th batch process, and the correction history information for the first to (n-1) th batch processes is included in the reference correction history information for the current batch. Before the start of the current batch (for example, at night outside business hours of the office center), the main control unit 210 (for example, a correction history higher list creation unit in the main control unit 210; not shown) generates a correction history upper list. To do.

  The correction history upper list will be described. In order to generate the correction history upper list, the main control unit 210 corrects the number of corrections SK [1, k] to SK [n− with respect to the kth registered pattern in the correction history information SJ [1] to SJ [n−1]. 1, k] is obtained as the misread count value PTN [k]. The misread count value PTN [k] is obtained for each of the first to Kth registered patterns. The misread count value PTN [k] represents the total number of times that the OCR amount information is corrected in the correction entry operation after the OCR amount information is obtained for the kth registered pattern in the reference period. The main control unit 210 sets the registration patterns corresponding to the first to xth largest misread count values among the misread count values PTN [1] to PTN [K], respectively, as the first to xth correction history upper ranks. Specify as a pattern. x may be any integer of 1 or more. However, the first to xth correction history upper patterns are specified for the purpose of narrowing down registered patterns having a relatively large misread count value from among K types of registered patterns (that is, the first to Kth registered patterns). Therefore, the value of x should be smaller than the value of K. Here, it is assumed that x = 3 (then, the number K of registered patterns is 4 or more). The revision history upper list is a list of the first to xth revision history upper patterns.

  When the search condition setting image 600 (see FIG. 15) is displayed, an operation for specifying the correction history search item 640 (operation for checking a box in the item 640) is input to the input unit 240. As shown in FIG. 24, the display control unit 218 pops up a list image 800 showing the correction history upper list in a partial area on the lower right side of the display unit 230 (superimposed display on the search condition setting image 600).

  The list image 800 includes items 810 [1] to 810 [3] indicating first to third correction history upper patterns. In the items 810 [1] to 810 [3], the pattern number and the pattern name of the corresponding correction history upper pattern are displayed. When an operation for specifying the item 810 [i] corresponding to the i-th modification history upper pattern is input to the input unit 240 (where i is 1, 2 or 3), the main control unit 210 (mainly 216 and 217). A correction history search operation is performed. When an operation for designating item 810 [i] is input, in the correction history search operation, in the current batch, the target form having the i-th correction history upper pattern as pattern information (that is, the form pattern is the i-th correction history upper rank). The stored amount information of the target form determined to be the pattern is searched as the correction candidate amount information.

  When an operation for specifying the item 810 [i], which can be expressed as follows, is input, in the correction history search operation, the search condition setting unit 216 selects the target form T [ 1] to T [m] include the OCR amount information included in the stored amount information in the searched amount information group, and store the target form having the i-th modification history upper pattern as pattern information from the searched amount information group. A search condition is set so that the amount information is searched as correction candidate amount information (that is, a search condition for searching for correction candidate amount information is set based on the correction history information), and the search processing unit 217 A search process for actually searching for the amount information satisfying the search condition is executed (that is, the stored amount information of the target form having the i-th correction history upper pattern is actually corrected from the searched amount information group) Search as the amount information). Since the search result depends on the correction history information SRJ [1] to SRJ [n-1], the search is considered to be executed using the correction history information SRJ [1] to SRJ [n-1]. good. A target form having the correction candidate amount information as the stored amount information may be called a correction candidate form. Then, in the item correction history search operation, it can be said that a target form having the i-th correction history upper pattern as pattern information is searched as a correction candidate form.

  When one or more pieces of correction candidate amount information are searched through the designation of the item 810 [i], the display control unit 218 displays a search result image including the searched correction candidate amount information (image 700, FIG. 20 in the example of FIG. 18). In this example, the image 702) is displayed on the display unit 230. The contents of the search result image, the operator's work performed after the search result image is displayed, and the operation of the control device 200 are the same as those described above. When the correction candidate amount information is not searched (that is, when the correction candidate amount information does not exist), in other words, when the storage amount information that satisfies the search condition does not exist, that fact is displayed on the display unit 230.

  When the search icon 611 is clicked after an operation for specifying the correction history search item 640 (operation for checking a box in the item 640) is input to the input unit 240, the above-described correction history search operation is performed. It may be performed. In this case, for example, the storage amount information of the target form having the first correction history upper pattern as pattern information may be searched from the group of searched amount information as the correction candidate amount information. You may make it search the memory | storage amount information of the object form which has either of two or more correction history superordinate patterns as pattern information among correction history superordinate patterns as correction candidate amount information.

  Although the cause of the target form having the same pattern as the correction history upper pattern is unknown, it can be said that misreading frequently occurs in the OCR process. By searching through the specification of the correction history search item 640, it is possible to easily find correction candidate amount information that is estimated to have a relatively high possibility of misreading in the OCR process, and the efficiency of the correction entry work. Can be raised. In particular, for example, with regard to forms related to public charges, the same type of form is often handled in a certain period (for example, one month), and there is one form in a collection of the same type of form handled in large quantities. When misreading occurs, it is highly likely that the same misreading occurs for other forms. If the number of occurrences of misreading (occurrence ratio) changes depending on the form pattern, search for patterns with a relatively high possibility of misreading using the correction history information. Efficiency increases greatly.

  In the above-described method, the correction history upper list is created based on the misread count values PTN [1] to PTN [K], but the correction history upper list is based on the misread rates PTN [1] ′ to PTN [K] ′. A list may be created. The misread rate PTN [k] 'has a value obtained by dividing the misread count value PTN [k] by the total number of target forms having the kth registration pattern and the OCR amount information obtained in the reference period. That is, the misread rate PTN [k] ′ represents the misread rate of the amount information (the misread rate of the OCR process) for the target form having the kth registration pattern in the reference period. In this case, the main control unit 210 registers registration patterns corresponding to the first to xth largest misreading rates among the misreading rates PTN [1] ′ to PTN [K] ′, respectively, from the first to the xth. What is necessary is just to specify as a correction history superordinate pattern, and the operation | movement after this specification is the same as that of what was mentioned above.

  However, when the misread rate is used, for example, when the total number of target forms having the kth registration pattern and the OCR amount information obtained during the reference period is considerably small (for example, when the total number is 2), the misread count Even if the value PTN [k] is slightly increased (for example, the misread count value PTN [k] is changed from 0 to 1), the k-th registered pattern rises to the correction history upper pattern. That is, the misread rate PTN [k] 'may change excessively with respect to the change of the misread count value PTN [k].

  With regard to forms related to utility bills, etc., the same type of form is often handled in a certain period (for example, one month), so the form of the first registration pattern is more than that of the second registration pattern during the reference period. If many were handled, there is a high possibility that many forms of the first registration pattern are included in the current batch. As an extreme example, if many forms of the first registration pattern are prominently handled in the reference period and the timing of performing batch processing of the current batch, the misread count value PTN [1] is 10,000 and the misread count value PTN. It is also conceivable that [2] becomes 1. In this case, if the first registered pattern corresponding to the misread count value of “10000” is included in the correction history upper list in preference to the second registered pattern corresponding to the misread count value of “1”, the correction is performed. It seems likely that the necessary amount information can be found earlier. If the correction history upper list is created using the misreading rate, the misreading rate corresponding to the second registration pattern will be 100% just by one misreading, and the second registration pattern will be the first registration. It is included prior to the correction history higher list than the pattern. This is not desirable from the viewpoint of finding money amount information that needs to be corrected earlier with respect to the current batch estimated to contain many forms of the first registration pattern.

  However, since the misreading rate PTN [k] ′ purely represents the rate of misreading for the kth registered pattern in the past, the misreading rate PTN [k] ′ is used to display the correction history upper list. There is no difference that the method of creating is useful, and depending on the situation, the amount information that needs to be corrected can be found more quickly by using the misreading rate PTN [k] ′.

  It should be noted that the correction history search operation functions beneficially for the amount information acquired by the OCR process, so that the target forms T [1] to T [m] are included in the searched amount information group in the correction history search operation. ] Is not included, but may be included as a modified example.

[Automatic search operation]
In the above description, it is assumed that the carry / overflow search operation, the first numerical value search operation, the last numerical value search operation, and the correction history search operation are each performed in response to an input of a corresponding operation. Of these four operations, any one, two, or three operations or all operations are performed only on the condition that the verification NG signal is output (that is, no operation to the input unit 240 is performed). It may be executed without any need).

  In this case, if one or more correction candidate amount information has been searched by any of the executed operations among the carry / overflow search operation, the first numerical value search operation, the final numerical value search operation, and the correction history search operation. The display control unit 218 causes the display unit 230 to display a search result image (image 700 in the example of FIG. 18 and image 702 in the example of FIG. 20) including the searched correction candidate amount information. The contents of the search result image, the operator's work performed after the search result image is displayed, and the operation of the control device 200 are the same as those described above. When the correction candidate amount information is not searched (that is, when the correction candidate amount information does not exist), in other words, when the storage amount information that satisfies the search condition does not exist, that fact is displayed on the display unit 230.

  In addition, the main control unit 210 is configured so that any two or more of the carry / overflow search operation, the start numerical value search operation, the end numerical value search operation, and the correction history search operation can be combined. Also good.

  For example, when the search icon 611 is clicked in a state where an operation for specifying the small item 632 and the correction history search item 640 in the designated number search item 630 is input to the input unit 240, the end numerical value search operation is performed. The amount information included in the searched amount information group at this time is limited to the stored amount information of the target form having the pattern information of the first to xth correction history upper patterns (where x is 1, 2, or 3, for example). Good to be done.

[Other search items]
With reference to FIG. 15 again, the search items 651 to 657 and the search items 661 to 663 included in the search condition setting image 600 will be described.

  When the search condition setting image 600 is displayed, the operator uses the input unit 240 to set the branch name, storage location, category, type, year, number of sheets, and amount of money in the search items 651 to 657, respectively. Can be entered (or their corresponding codes can be entered). When the search icon 611 is clicked after making the input, the search processing unit 217 searches the target form (the stored amount information of the target form) associated with the input content based on the storage content of the storage unit 250. To do. When one or more search forms are searched, a search result image including the search hit item Q for the searched target form is displayed. In the search hit item Q here, as in the search hit item 710 shown in FIG. 18, information (including at least storage amount information) based on the set information of the searched target form is displayed. The operation after the search hit item Q is displayed is the same as the operation after the search hit item 710 is displayed.

When the search condition setting image 600 is displayed, the operator can specify the OCR reliability in the search item 661 in four stages using the input unit 240. For convenience, the OCR reliability is represented by the symbol R _OCR . When the OCR reliability is specified in the first, second, third, and fourth stages in the search item 661 and the search icon 611 is clicked, the search processing unit 217 causes the target forms T [1] to T [ m], among the target forms in which the OCR amount information is stored as the stored amount information, “R _OCR ≦ TH1”, “TH1 <R _OCR ≦ TH2”, “TH2 <R _OCR ≦ TH3”, respectively. A target form having OCR reliability satisfying “TH3 <R _OCR ” (stored amount information of the target form) is searched. “TH1 <TH2 <TH3 <100”, and TH1 is larger than the above-described lower limit reliability. Of the first to fourth stages, two or more stages can be designated at the same time. When one or more search forms (stored amount information) are searched, a search result image including a search hit item Q for the searched target form is displayed. In the search hit item Q here, as in the search hit item 710 shown in FIG. 18, information (including at least storage amount information) based on the set information of the searched target form is displayed. The operation after the search hit item Q is displayed is the same as the operation after the search hit item 710 is displayed. For example, when a relatively low OCR reliability is searched using only the search item 661 from 1000 (1000) target forms, 200 to 300 target forms are searched and extracted. It generally happens. As an example, if you try to process 100,000 target forms per day, 100 times the target forms are searched and extracted, so it takes a lot of man-hours to find the target forms that need to be corrected. Cost.

  When the search condition setting image 600 is displayed, the operator can specify the search items 662 and 663 using the input unit 240. When the search items 661 and 663 are specified and the search icon 611 is clicked, the search processing unit 217 assigns 1 to the SOCR flag among the target forms T [1] to T [m] of the current batch. And those in which 1 is assigned to the manual input flag. When one or more search forms are searched, a search result image including the search hit item Q for the searched target form is displayed. In the search hit item Q here, as in the search hit item 710 shown in FIG. 18, information (including at least storage amount information) based on the set information of the searched target form is displayed. The operation after the search hit item Q is displayed is the same as the operation after the search hit item 710 is displayed. In addition, since there is no image data for the target form in which 1 is assigned to the manual input flag, the target form in which 1 is assigned to the manual input flag is searched as the target form corresponding to the search hit item 710. The operator corrects the money amount information for the target form as necessary while visually checking the actual form of the target form placed on a predetermined shelf or the like.

The digit / overflow search operation, the first numerical value search operation, the final numerical value search operation, and the correction history search operation may be performed by combining any of the items 651 to 657 and 661 to 663. That is, for example, after specifying an amount range of “10000 yen” or more and less than “100,000 yen” in the search item 657, a digit / overflow search operation, a leading numeric search operation, a trailing numeric search operation, or a correction history search operation The amount information included in the searched amount information group in those operations may be limited to the amount information within the amount range.
Similarly, for example, when a first-stage OCR reliability is specified in the search item 661 and a digit drop / overflow search operation, a first numerical value search operation, a final numerical value search operation, or a correction history search operation is performed. In this operation, the amount information included in the searched amount information group may be limited to the stored amount information of the target form having the OCR reliability (R _OCR ) satisfying “R _OCR ≦ TH1”.
Similarly, for example, when a specific branch name is specified in the search item 651 and a digit / overflow search operation, a leading numerical value searching operation, a trailing numerical value search operation, or a correction history search operation is performed, The amount information included in the searched amount information group may be limited to the stored amount information of a target form associated with a specific branch name (a target form including a specific branch name in information other than the amount).

[Modifications, etc.]
The embodiment of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the claims. The above embodiment is merely an example of the embodiment of the present invention, and the meaning of the term of the present invention or each constituent element is not limited to that described in the above embodiment. The specific numerical values shown in the above description are merely examples, and as a matter of course, they can be changed to various numerical values.

  The search condition setting unit 216 may be considered as a part that selects and sets a condition for searching for correction candidate amount information from a plurality of conditions, and the search processing unit 217 instructs the search condition setting unit 216 to It can be considered that the correction candidate amount information is searched in accordance with the conditions selected and set. For example, among the plurality of conditions, a first condition for performing a carry / overflow search operation, a second condition for performing a leading numerical value search operation, and a third condition for performing a trailing numerical value search operation. It may be considered that two or more conditions among the fourth conditions for performing the condition and the correction history search operation are included.

  In the above-described embodiment, it is assumed that the main component of the form processing system is included in the form processing apparatus 100 and the control apparatus 200 arranged in the business center. However, any one of the constituent elements of the form processing system is assumed. The unit may be provided in an external device (for example, a device other than the server device SV or the server device SV (not shown)) different from the form processing device 100 and the control device 200.

  For example, the scanner unit 113 may not be built in the form processing apparatus 100, and may be disposed in each branch. In this case, for example, the image data acquired by the scanner unit 113 is transmitted to the control device 200 from a device arranged at each branch via wired or wireless communication or via a recording medium (not shown). Just keep it. The image data acquired by the scanner unit 113 may be transmitted to the control device 200 via the server device SV. For example, the display unit 230 may be provided in an external device different from the control device 200 (for example, a device (not shown) other than the server device SV or the server device SV). From another viewpoint, the content described as being displayed on the display unit 230 may be displayed on a display unit of an external device different from the control device 200. Similarly, for example, the input unit 240 may be provided in an external device different from the control device 200 (for example, a device (not shown) other than the server device SV or the server device SV). From another viewpoint, the content described as being input to the input unit 240 may be input to an input unit of an external device different from the control device 200.

  Whether each functional block (211 to 219; see FIG. 7) of the main control unit 210 is also provided in the main control unit 210 for each functional block may be determined. For example, the OCR processing unit 213 may be provided in an external device different from the control device 200 (for example, a device (not shown) other than the server device SV or the server device SV). In this case, the result of the OCR process may be transmitted from the external device to the control device 200 via wired or wireless communication or via a recording medium (not shown). The same applies to other functional blocks. Similarly, the storage units 251 to 256 may be provided in an external device different from the control device 200.

  The reference total amount information and the calculated total amount information are forms of the reference total value and the calculated total value, respectively. The reference total value and the calculated total value may be numerical information (for example, number information, weight information) representing other than the amount of money.

<< Consideration of the Present Invention >>
Consider the technology of the present invention embodied in this embodiment.

The form processing system W _{1 according} to one aspect of the present invention includes an image acquisition unit (113) that acquires images of a plurality of forms, and a recognition unit that recognizes money amount information for each form from the images of a plurality of forms ( 213), input means (240) for receiving the amount information of the form whose amount information could not be recognized by the recognition means, first amount information as amount information recognized by the recognition means, and the input means The storage means (250) for storing the second amount information, which is the amount information inputted in the above, and the condition for searching for the candidate for the amount information requiring correction from the amount information stored in the storage means is set. Search condition setting means (216) for performing information search means for searching for money amount information as the candidate according to the conditions set by the search condition setting means from the money amount information stored in the storage means And 217), and display means for displaying a money amount information retrieved by said information retrieval means (230), characterized in that it comprises a.

  As a result, money amount candidates that need to be corrected are retrieved and displayed, so that the efficiency of the required correction work can be improved. Note that the input unit may be considered to include the entry unit 214.

Specifically, for example, in the form processing system W ₁ , the condition that can be set by the search condition setting means may be a digit error in the money amount information entered through the input means. A condition for searching for money amount information as the candidate is included, and the digit error of the money amount includes a money amount information input via the input means and a form corresponding to the money amount information input via the input means. It may be the difference of the digit of the amount between the amount information described in the above.

  As a result, it is possible to search for money amount information (amount information that needs to be corrected) that includes a digit error that frequently occurs with respect to the money amount information input via the input means, and the efficiency of the required correction work. Is achieved.

Further, for example, in the form processing system W ₁ , the conditions that can be set by the search condition setting unit include the candidate based on at least one of the first numerical value and the final numerical value in the first amount information stored in the storage unit. Conditions for searching may be included.

  As a result, it is possible to search for money amount information that may be misrecognized with respect to the yen mark (¥) and / or misrecognized with respect to the right end of the money amount entry column, thereby improving the efficiency of necessary correction work.

Also, for example, the form processing system W ₁ includes a pattern dictionary storage unit (256) that stores feature information of a plurality of registered patterns, and the pattern pattern of each form based on the storage contents of the pattern dictionary storage unit and the image of each form. A pattern identifying means (212) for identifying which of a plurality of registered patterns, a correction means (214) for correcting one or more amount information stored in the storage means in response to an input of a correction instruction; The search condition setting unit further includes a correction history information storage unit (255) that stores the history of the input of the correction instruction as correction history information in association with the form pattern corresponding to the corrected amount information. The settable condition may include a condition for searching for the candidate based on the correction history information.

  If there is a history of revisions to the amount information of a form having a pattern in the past, it is estimated that there is a high possibility that the amount information of the form having the pattern needs to be corrected this time. . With the above configuration, it is possible to search for monetary information that has a relatively high possibility of needing correction in response to such estimation. It is done.

More specifically, for example, the form processing system W ₁ uses the pattern identifying means for identifying the pattern of each form using the pattern identifying means, obtaining the first amount information using the recognizing means, and using the input means. Batch processing including acquisition of the second amount information and correction using the correction unit can be sequentially executed a plurality of times, and the search condition setting unit performs the batch processing in the n-th batch processing. When a condition for searching for the candidate is set based on the correction history information, the information search means uses the correction history information for the first to (n-1) th batch processes as the candidate. (N is an integer of 2 or more).

Further, for example, the form processing system W ₁ includes reference total amount information acquisition means for acquiring reference total amount information that is a sum of a plurality of amount information described in the plurality of forms, and the first amount stored in the storage means. The determining means (215) for determining whether or not the calculated total amount information calculated from the one amount information and the second amount information matches the reference total amount information, and if it is determined that they do not match, It is preferable to further include display control means (218) for displaying a search condition setting image (600) for receiving setting of conditions for searching for candidates on the display means.

  This makes it possible to search for candidates for the first amount information and / or the second amount information that need to be corrected to match the reference total amount information and the calculated total amount information, and thus improve the efficiency of the necessary correction work. . Note that the reference total amount information acquisition unit is formed including, for example, the OCR processing unit 213 or the input unit 240 in the above-described embodiment.

Alternatively, for example, the form processing system W ₁ includes a reference total amount information acquisition unit that acquires reference total amount information that is a sum of a plurality of amount information described in the plurality of forms, and the first amount stored in the storage unit. A determination means (215) for determining whether or not the calculated total amount information calculated from the one amount information and the second amount information matches the reference total amount information; And a notification means for performing the notification.

  Thereby, it is possible to notify the user of the form processing system of the mismatch between the reference total amount information and the calculated total amount information.

More specifically, for example, the form processing system W ₁ stores a reference total amount information acquisition unit that acquires reference total amount information that is a sum of a plurality of amount information described in the plurality of forms, and the storage unit stores the reference total amount information. Determination means (215) for determining whether or not the calculated total amount information calculated from the first amount information and the second amount information calculated matches the reference total amount information, and the information search When it is determined that they do not match, the means is the difference information between the reference total amount information and the calculated total amount information, and the first numerical value of the first amount information, according to the condition set by the search condition setting unit Alternatively, the candidate may be searched based on the last numerical value of the first amount information.

  By using the difference information, it becomes possible to search for money amount information (amount information that needs to be corrected) including a digit error that often occurs with respect to the money amount information input via the input means. The efficiency of the correction work is improved. By using the first numerical value and the final numerical value of the first monetary amount information, it is possible to search for monetary information that has the possibility of misrecognition of the yen mark (¥) and misrecognition of the right end of the monetary entry column, and necessary correction work Efficiency.
