FIG. 13 is a diagram showing an example of journal data for the display screen 70 in the accounting processing device 1 according to the present embodiment.

The receipt image processing described with reference to FIG. 8 is a process executed at the accounting office, for example, at the timing when the receipt 6 is received from the adviser to the accounting office, or at a regular timing such as once a month. is there. The receipt image processing can also be performed on one receipt 6, or can be collectively processed on a plurality of receipts 6.

When the user of the accounting office activates the receipt processing program 31a stored in the accounting processing device 1, the control unit 10 of the accounting processing device 1 outputs an initial screen (not shown) to the display unit 46. Then, when the user of the accounting office selects or inputs an adviser from the initial screen, in step S (hereinafter, simply referred to as “S”) 11 of FIG. 8, the control unit 10 of the adviser Accept the designation.

When the control unit 10 of the accounting processing device 1 receives the designation of the adviser, the control unit 10 then outputs, for example, a screen (not shown) instructing the scanner 5 to capture the receipt 6 to the display unit 46. Causes the scanner 5 to read the receipt 6 of the designated adviser. Since the scanner 5 reads the receipt 6, generates the receipt image, and transmits the receipt image to the accounting processing device 1, the control unit 10 (receipt image receiving unit 11) is transmitted from the scanner 5 in S12. Accept receipt images. The control unit 10 receives the receipt image generated for each receipt 6. For example, when the number of receipts 6 read by the scanner 5 is one, the number of receipt images is one, and when the number of receipts 6 is multiple, the number of receipt images is multiple.
Then, the control unit 10 (receipt image receiving unit 11) assigns an image ID and stores the received receipt image in the receipt image storage unit 32 (see FIG. 3).

In S13, the control unit 10 (receipt image processing unit 12) analyzes the receipt image. More specifically, the control unit 10 (text processing unit 13) analyzes the receipt image and acquires various information from the receipt image. The control unit 10 acquires text data from the receipt image by performing character recognition processing on the receipt image. The process of acquiring text data from the receipt image (character and number recognition process by OCR technology or the like) can be performed by using a known method. Then, the control unit 10 searches the text data and acquires various information. The various types of information refer to, for example, the name of the store (customer) included in the receipt image, the date, and the like.
In S14, the control unit 10 (item confirmation processing unit 14) performs the item confirmation process.

Here, the item confirmation process will be described with reference to FIG.
In S21 of FIG. 9, the control unit 10 (item confirmation processing unit 14) extracts an item line from the text data obtained from the receipt image. The process of extracting the item line from the text data can be performed by using a known method. Specifically, the control unit 10 may, for example, extract a row containing an item that matches an item registered in an item DB (database) (not shown), or is above the "subtotal" and "¥". May be extracted.
FIG. 10 shows an example in which item lines 61a and 61b are extracted from the receipt image 60.

In S22 of FIG. 9, the control unit 10 (detailed processing unit 22) generates detailed data, and the detailed data storage unit 33 (see FIG. 4) stores the generated detailed data. At that time, the control unit 10 may assign the detail ID uniquely.
In S23, in the control unit 10 (item confirmation processing unit 14), the combination of the item in the item line and the reduced tax rate mark is equal to the classification result by the learning model (first learning model) stored in the learning model storage unit 34. Make sure that.

Here, the learning model will be briefly described. There are multiple learning models depending on the learning content described later. The item determination learning model (first learning model) is a model in which the items shown in the reduced item storage unit 35 are subject to the reduced tax rate, and the items and the presence / absence of the reduced tax rate are learned.
The control unit 10 inputs the item as input data to the first training model for each extracted item line. By doing so, the first learning model outputs whether or not the item is subject to the reduced tax rate. Then, the control unit 10 confirms that the combination of the item in the item line and the reduced tax rate mark is equal to the classification result by the first learning model.

In S24, the control unit 10 (item confirmation processing unit 14) outputs the confirmation result by S23 to the display unit 46. Here, as a confirmation result, the control unit 10 may output only those whose combinations do not match, or may output all of them, not limited to the matching / mismatching of the combinations. Further, as a confirmation result, not only the item in the item line and the reduced tax rate mark but also the amount may be displayed together.
In S25, the control unit 10 (item confirmation processing unit 14) determines whether or not the change content has been accepted as confirmation data for the confirmation result from the user. When the changed content is accepted (S25: YES), the control unit 10 shifts the process to S26. On the other hand, when the change content is not accepted (S25: NO), the control unit 10 shifts the process to S15 in FIG. When the changed contents are accepted, the changed user, the changed date and time, and the changed contents (items in the item line, reduced tax rate mark and amount, etc.) are saved as the change history 1 in the history DB (not shown). You may.

In S26, the control unit 10 (detail processing unit 22) updates the detail data of the detail data storage unit 33 based on the changed contents.
In S27, the control unit 10 (item confirmation processing unit 14) updates the first learning model of the learning model storage unit 34 by using the change content data and the change history 1.
The control unit 10 may update the mitigation item storage unit 35 and the item DB (not shown) using the data of the changed contents. Further, the processes of S26 and S27 may be performed at the same time, or the process of S27 may be performed before the process of S26. By updating the first learning model of the mitigation item storage unit 35, the item DB, and the learning model storage unit 34, the accuracy of extracting the mitigation items can be improved.
After that, the control unit 10 shifts the processing to S15 in FIG.

In S15 of FIG. 8, the control unit 10 performs a total amount confirmation process.
Here, the total amount confirmation process will be described with reference to FIG.
In S31 of FIG. 11, the control unit 10 (keyword extraction unit 15) extracts the extraction keyword stored in the extraction keyword storage unit 36 from the text data obtained from the receipt image. In the receipt image 60 of FIG. 10, the item stored in the extraction keyword storage unit 36 is "total" for the "total amount", the item is "10% consumption tax sale" for the "10% amount", and the item is. "8% consumption tax sale" for "8% amount" is extracted from the text data.

In S32, the control unit 10 (amount reading unit 16) acquires the value of the amount from each extracted keyword line. Then, the control unit 10 stores the value of the acquired amount of money for the corresponding item of the target record of the receipt image storage unit 32 (see FIG. 3).
In S33, the control unit 10 (amount determination unit 17) performs determination processing on the acquired amount value. Specifically, the control unit 10 adds the total total amount, which is the value of the amount corresponding to the "total amount", and the breakdown amount, which is the value of the amount corresponding to the "10% amount" and the "8% amount". It is determined whether or not the value is matched.

In S34, the control unit 10 (image processing unit 18) performs processing on the receipt image. As a processing process, the control unit 10 surrounds, for example, a portion of the receipt image in which each amount of money acquired in S32 is described with a rectangle.
The processing is not limited to being surrounded by a rectangle, and various modes can be considered. For example, the amount portion may be underlined. Further, the color of the rectangular line or the underline may be different. Further, the inside of the rectangle may be shaded with different colors.

In S35, the control unit 10 (display screen generation unit 19) generates item amount information. Further, the control unit 10 (display screen generation unit 19) generates a display screen including the generated item amount information and the receipt image processed by the processing of S34.
FIG. 12 shows an example of the display screen 70.
First, the control unit 10 generates item amount information 71 in which the amount image acquired from the receipt image and the amount value are arranged side by side in the item corresponding to the extracted keyword extracted by S31. Here, the monetary amount image is a cutout of a portion where the monetary amount is described from the processed receipt image that has been processed in S34. The value of the amount is a number obtained from the text data of the receipt image.
It is desirable that the control unit 10 generates the value of the amount of money in an emphasized manner, for example, by showing it in red, when there is a discrepancy in the processing by S33.

The item amount information 71 shown in FIG. 12 includes information 75 regarding the “total amount”, information 73 regarding the “10% amount”, and information 74 regarding the “8% amount”. For example, the information 74 includes image information 74a and numerical information 74b. The image information 74a is a monetary amount image, and the numerical information 74b is a monetary value. Similarly, each amount includes image information and numerical information. In the item amount information 71, the date information 72 is also arranged side by side in the same manner as the information related to the amount. Information 72 can be obtained from text 62.
Next, the control unit 10 generates a display screen 70 in which the generated item amount information 71 and the processed receipt image 60a are arranged. The arrangement position of the item amount information 71 shown in FIG. 12 and the receipt image 60a is an example.

In S36 of FIG. 11, the control unit 10 (screen output unit 20) outputs the generated display screen 70 to the display unit 46. By doing so, the user can refer to, for example, the display screen 70 shown in FIG. 12 and confirm that the amounts are correct. In addition, if the amounts do not match or are entered incorrectly, the user can correct the amounts. When the correction of the amount of money is accepted, the changed user, the change date and time, and the change contents (item amount information and amount of money, etc.) may be saved in the history DB as the change history 2.
After that, the control unit 10 shifts the processing to S16 of FIG.

In S16 of FIG. 8, the control unit 10 determines whether or not the correction data has been accepted. For example, on the display screen 70 shown in FIG. 12, when the user corrects the value of the amount of money and selects the "update" button, the control unit 10 receives the corrected data. When the correction data is received (S16: YES), the control unit 10 shifts the process to S17. On the other hand, when the correction data is not accepted (S16: NO), the control unit 10 shifts the processing to S18. The case where the correction data is not accepted is, for example, a case where the user selects the "confirmation" button on the display screen 70 shown in FIG.

In S17, the control unit 10 updates the value corresponding to a predetermined item among the target records of the receipt image storage unit 32 to the value of the correction data.
In S18, the control unit 10 generates journal data. The journal data is "sticky note", "receipt", "number", "month", "day", "debit", "credit", "amount", "summary", "section", and "tax zone". It consists of items. The "sticker" indicates the presence or absence of a sticker, the "receipt" is the receipt image 60a which is the source of the journal data, the "number" is the number for identifying the journal data, and the "month" and "day" are related to the date. Information 72, "debit" and "credit" are debit and credit accounts, "amount" is debit or credit amount, "summary" is supplementary content for the item, and "section" is , The tax classification for transactions, and the "tax zone" indicates the tax rate classification. Based on the value of the amount of money on the display screen 70 shown in FIG. 13 (A), the journal data 81 shown in FIG. 13 (B) and the journal data 82 shown in FIG. 13 (C) are generated. The value "489 (yen)" of the amount of the journal data 81 in FIG. 13 (B), the value "31 (indicating a taxable transaction)" of the section, and the value "10 (%)" of the tax zone are shown in FIG. 13 (B). It corresponds to the value "489 (yen)" of the 10% amount of the information 73 of A). Further, the value "480 (yen)" of the amount of the journal data 82 in FIG. 13 (C), the value "31 (indicating taxable transaction)" of the section, and the value "8 (%)" of the tax zone are shown in FIG. It corresponds to the value "480 (yen)" of the 8% amount of the information 74 of 13 (A). After that, the control unit 10 ends this process.

(Modification example 1)
The method of extracting various information from the receipt image is not limited to the method in the above-described embodiment.
FIG. 14 is a diagram for explaining another item extraction method in the accounting processing apparatus 1 according to the present embodiment.
In the example of FIG. 14, the extraction keyword is extracted after narrowing the extraction range.
From the receipt image 60 shown in FIG. 14 (A), the control unit 10 (predetermined word extraction means) selects the text 90 of the “subtotal” and the text 91 including the “mitigation” as shown in FIG. 14 (B). Search. Here, words such as "subtotal" and "reduction" are stored in advance in the storage unit 30 (predetermined word storage unit).

Then, based on these two texts, the control unit 10 (range setting means) divides the area into the transaction content area 92 and the aggregation area 93 as shown in FIG. 14C.
By dividing the area in this way, the control unit 10 can search for the extracted keyword using the aggregation area 93 as the search range, and as shown in FIG. 14D, the lines 163 to 165 including the extracted keyword can be searched. Can be extracted. Further, the control unit 10 can search for an item from the transaction content area 92 and extract an item line.
By limiting the search range in this way, the recognition rate can be further improved.

The reading accuracy can be improved by further adding an element related to "date" and a text of "total" to the storage unit 30 (predetermined word storage unit) and making it a search target.

(Modification 2)
The extracted keywords are not limited to the stored contents in the above-described embodiment.
FIG. 15 is a diagram showing an example of another extracted keyword storage unit 236 in the accounting processing device 1 according to the present embodiment.
The extracted keyword storage unit 236 (issuer storage unit, extracted keyword storage unit) associates the customer code (issue identification information) with the customer image, the total amount, the 10% amount, and the 8% amount. The image (image data) for each item is stored. The image to be stored corresponding to each item is an image included in the receipt image. For example, the business partner image is characteristic information indicating the business partner included in the receipt image.

In this way, the control unit 10 (issue identification acquisition means) can first identify the customer code corresponding to the extracted feature information by extracting the feature information from the receipt image. Then, the control unit 10 can extract the extraction keyword by collation with an image. Further, since the extraction keyword is stored for each business partner, the extraction keyword corresponding to each business partner can be used, so that the efficiency of the extraction process can be improved.

The extracted keyword storage unit may store the extracted keywords as text data for each business partner. By doing so, the extraction of the extracted keyword is based on the text data, but since the extracted keyword corresponding to each business partner can be obtained, the efficiency of the extraction process can be improved even in that case.

As described above, according to the accounting processing system 100 of the present embodiment, there are the following effects.
(1) The accounting processing device 1 extracts a plurality of extraction keywords corresponding to different types of total amounts such as "total amount", "10% amount", and "8% amount" from the receipt image which is the image data of the receipt 6. Extract and get the text data of the amount from the line containing the extracted keyword. Then, the accounting processing device 1 generates item amount information including the text data of the acquired amount and the item indicating each corresponding total, and displays it on the display unit 46.
Therefore, it is possible to output information on accounting treatment for a plurality of tax rates so that the user can easily see it. In addition, it is possible to create journal data based on the output information, and it is possible to support journal input.

(2) Since the accounting processing device 1 outputs the display screen 70 including the item amount information and the receipt image to the display unit 46, the user compares the receipt image with the item amount information generated from the receipt image. You can make it easier to do.
(3) The accounting processing device 1 processes the receipt image to emphasize the image in which the amount of money included in the item amount information is acquired, and displays the processed receipt image in the display unit 46. It is possible to make it easier for the user to compare the amount of the receipt image and the item amount information.
(4) The accounting processing device 1 can provide the user with information that can be visually distinguished by making the processing of the receipt image different for each item.

(5) Since the accounting processing device 1 confirms the combination of the item and the reduced tax rate based on the item determination learning model (first learning model), it is easy to determine whether the combination is accurate. be able to.
In addition, since the learning model is updated by receiving confirmation data including changes from the user who confirmed the confirmation result, the judgment by the learning model is made more accurate by reflecting the description of the actual receipt image. it can.

(6) The accounting processing device 1 determines whether or not the value corresponding to the "total amount" matches the sum of the value corresponding to the "10% amount" and the value corresponding to the "8% amount". However, in the case of a mismatch, the display mode of the item amount information 71 is set to indicate that there is a mismatch. Therefore, it is possible to show at a glance that there is a discrepancy.

(7) The accounting processing device 1 registers the receipt image and the data of each total amount in the receipt image storage unit 32. Therefore, each total amount can be easily used, and if there is a correction, the correction content can be easily reflected. Then, journal data can be generated from the data stored in the receipt image storage unit 32.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Moreover, the effects described in the embodiments are merely a list of the most preferable effects arising from the present invention, and the effects according to the present invention are not limited to those described in the embodiments. The above-described embodiment and the modified form described later can be used in combination as appropriate, but detailed description thereof will be omitted.

(Transformed form)
(1) In the embodiment, the extracted keyword storage unit has been described as an example of storing in association with an item indicating the total of different amounts of money, but the present invention is not limited to this. Further, date information may be associated and stored. For example, items used by September 30, 2019, items used after October 1, 2019, and so on, the period (applicable period) is associated in consideration of the case where the tax rate is changed. Then, the control unit 10 (date extraction means) extracts the date from the receipt image, and the control unit 10 (extraction keyword selection means) extracts the extracted keyword from the range of the period including the corresponding date according to the extracted date. Select. By doing so, for example, the items can be made different before and after the application of the reduced tax rate and before and after the change of the tax rate, so that the convenience is improved.

In addition, processing other than item confirmation may also be performed by learning processing by AI using a learning model. Specifically, the application period determination learning model using the extracted keyword (hereinafter, also referred to as the second learning model) is applied from the combination of the date information (including the application period) and the extracted keyword (including the predetermined word). This is a model that learns the period and whether or not the tax rate is changed. The control unit 10 inputs the extracted date information and the extracted keyword (including a predetermined word) into the second learning model as input data. By doing so, the second learning model outputs whether the receipt image is before the application of the reduced tax rate or after the application of the reduced tax rate, depending on the presence or absence of the extracted keyword (including the predetermined word).
Then, the control unit 10 (extracted keyword confirmation means) confirms that the combination of the date information and the extracted keyword (including the predetermined word) is equal to the classification result by the second learning model.

The control unit 10 (confirmation result output means) outputs the confirmation result to the display unit 46, and when the control unit 10 (confirmation receiving means) accepts the change contents for the confirmation result, the control unit 10 (learning means) Updates the extracted keyword storage unit, the predetermined word storage unit, and the application period determination learning model (second learning model) of the learning model storage unit 34 based on the changed contents. By updating the extracted keyword storage unit, the predetermined word storage unit, and the second learning model of the learning model storage unit 34, it is possible to improve the accuracy of the determination (whether the receipt image is before or after the application of the reduced tax rate). it can. If the combination of the extracted keyword and the date information cannot be used for determination, the accuracy of the determination may be further improved by further combining predetermined words.

In addition, for example, a storage method for classified invoices, qualified invoices (eg, invoices, invoices, receipts, receipts, etc.), etc. (qualified invoices, qualified simplified invoices (eg, invoices, invoices, etc.) Receipts, receipts, etc.)) It is also possible to determine whether or not a receipt image is eligible based on the presence or absence of items to be described depending on the type of receipt image, such as the storage method.
Here, the items to be described according to the type of receipt image are a. Transaction date, b. Transaction details (if the item is subject to the reduced tax rate, that fact), c. The total amount of consideration (excluding or including tax) and applicable tax rate for each tax rate, d. Consumption tax amount, e. The name and registration number of the business operator to whom the documents are issued. Specifically, the presence or absence of transaction details including item and item amount information (including extracted keywords), the presence or absence of the reduced tax rate mark, and the qualified invoice issuing business operator. Judgment is made based on the presence or absence of a registration number, the presence or absence of a business name of a qualified invoicing business operator, date information (including transaction date and applicable period), consumption tax amount, etc. (including applicable tax rate).

In addition, the receipt image is obtained by the learning process by AI using the eligibility judgment learning model (hereinafter, also referred to as the 4th learning model) which has learned the characteristics of the presence / absence of the description item according to the type of the receipt image and the calculation method of the consumption tax amount. Determine if you are eligible. By further learning the fourth learning model using these determination results, the control unit 10 (receipt image determination means) can improve the accuracy of determining whether or not the receipt image is qualified.

Specifically, the consumption tax amount, etc. is calculated from the total amount by utilizing the fact that the total differs depending on the fraction processing of the consumption tax (OK case), or the consumption tax for each individual product. It is also possible to determine whether or not the receipt image is eligible by the method of calculating the consumption tax, which is displayed for the amount (in the case of NG). Therefore, the control unit 10 classifies the item rows according to the presence or absence of the reduced tax rate for each item row extracted during the above-mentioned item confirmation process, and calculates the total of the item rows subject to the reduced tax rate and the total of the item rows not subject to the reduced tax rate. However, by applying each tax rate, the breakdown amount subject to the reduced tax rate (for example, 8% calculated amount), the breakdown amount not subject to the reduced tax rate (for example, 10% calculated amount), and the total calculated amount (8% calculation) The sum of the amount and the 10% calculated amount) can be calculated. Then, the control unit 10 combines the combination of the breakdown amount and the total total amount of the items of "10% amount" and "8% amount" acquired from the amount reading unit 16 and the calculated breakdown amount (8% calculation amount and 10%). The method of calculating the consumption tax can be determined by determining whether the combination of the calculated amount) and the total calculated total amount match. This makes it possible to identify the cause of the discrepancy in the amounts (whether the amount is misrecognized in the item line, or the breakdown amount or the total amount is misrecognized).

In addition, if the amounts do not match or are entered incorrectly, the user can correct the amounts. When the correction of the amount is accepted, the changed user, the change date and time, and the change contents (item amount information and amount, etc.) may be saved in the history DB as the change history 2, or the change contents and changes may be saved. The fourth learning model may be updated using the history and 2. Further, by updating the history DB and the fourth learning model of the learning model storage unit 34, the control unit 10 receives each item of the generated item amount information 71 (information 75 regarding "total amount" and "10% amount". The accuracy of the value of the amount of information 73 and the information 74) regarding "8% amount" can also be improved.

Further, since it is possible to use a plurality of known recognition processing techniques, the comprehensive judgment learning model described later learns the change history 1 and the change history 2 for each recognition process from the history DB, so that the execution time is long. Even if the user simply sets a processing policy such as giving priority to recognition accuracy or prioritizing execution time over recognition accuracy, a comprehensive judgment learning model such as AI is automatically set based on the processing policy set by the user. Hereinafter, the third learning model) may select and execute the optimum recognition process. Specifically, when the user sets the policy of "priority is given to recognition accuracy", the control unit 10 uses a recognition process having high character recognition accuracy to recognize the item in the item line and the reduced tax rate mark. To recognize the amount of money, switch to the recognition process with high recognition accuracy of numbers. By combining the multiple learning models described above, the information required for the user to create a journal from the receipt image by setting the policy of "priority is given to recognition accuracy" (whether the receipt image is eligible, whether or not there is a reduced tax rate, Transaction details, transaction amount, consumption tax, etc.) can be acquired efficiently.

(2) In the embodiment, each information stored in the storage unit has been illustrated and described, but the present invention is not limited thereto. In particular, the items may have other items or unnecessary items may be deleted. In addition, there are various tables required as an accounting processing device, but the description is omitted in the present embodiment.
