First Exemplary Embodiment

FIG. 6 is a sequence chart of a process performed by the information processing system 1 of a first exemplary embodiment.

According to the first example embodiment, the user sets multiple receipts as examples of recording media side by side on the image reader 608 in the image forming apparatus 600 (see FIG. 4).

The user then presses a start button (not illustrated) on the image forming apparatus 600 to provide an instruction to start reading the receipts (step S101). In other words, the user provides the instruction to start reading information recorded on the receipts.

The image reader 608 serving as an example of the reading unit reads multiple receipts (step S102), thereby capturing a read image. Specifically, the image reader 608 captures the read image including multiple receipt images respectively representing receipts.

In other words, the image representing each receipt is an example of a medium image and the image reader 608 captures the read image including multiple medium images.

According to the first example embodiment, the image forming apparatus 600 transmits the read image to the management server 300 and the management server 300 captures the read image.

Specifically, the receipt registration unit 351 extracts a rectangular-shaped image (hereinafter simply referred to as a “rectangular image”) included in the read image (step S103).

The image separator 353A in the information acquisition unit 353 separates each of the rectangular images from an image surrounding the rectangular image (step S104). The image rotator 353B rotates each of the rectangular images to upright the rectangular image (step S105).

The OCR unit 353C performs an optical character recognition (OCR) operation (step S106), thereby acquiring information included in each of the upright rectangular images.

In other words, the OCR unit 353C acquires, entry information, information recorded on each of the receipts.

The OCR unit 353C acquires as the entry information recorded on each of the receipts, character information, such as date and amount of money. According to the first exemplary embodiment, the entry information recorded on the receipts is acquired on a per receipt basis.

According to the first exemplary embodiment, the information acquisition unit 353 outputs the image of each receipt (upright rectangular image, hereinafter referred to as a “receipt image”) and the entry information acquired from each of the receipt images.

According to the first exemplary embodiment, there is a possibility that the OCR unit 353C fails to acquire the entry information. The information acquisition unit 353 compensates for a location of the acquisition failure of the entry information using a predetermined default value.

In other words, the information acquisition unit 353 outputs as the entry information the predetermined default value for the location where the acquisition of the entry information fails. In such a case, the entry information that is different from the original entry information is output.

Specifically, if the print of the receipt is light or the receipt is folded, the reading of the receipt may be difficult.

This may lead to an irregularity in which the acquisition of the entry information is not possible. As described above, the information acquisition unit 353 compensates for the location of the acquisition failure of the entry information with the predetermined default value and thus outputs the default value.

According to the first exemplary embodiment, the failure location identifying unit 352 extracts an image of the location where the OCR unit 353C has failed to acquire the entry information (failure location image). The information acquisition unit 353 outputs the extracted failure location information in association with the receipt image.

According to the first exemplary embodiment, the information acquisition unit 353 outputs the receipt image, entry image, and failure location image (step S107).

Specifically, the information acquisition unit 353 outputs the receipt image, entry image, and failure location image for the receipt from which the OCR unit 353C has failed to acquire the entry information. The information acquisition unit 353 outputs the receipt image and entry information for the receipt from which the OCR unit 353C has successfully acquired the entry information.

According to the first exemplary embodiment, the receipt registration unit 351 determines whether the OCR operation has been successful or not (step S108).

Specifically, the receipt registration unit 351 determines whether the information output by the information acquisition unit 353 includes a failure location image.

If the information output from the information acquisition unit 353 includes a failure location image, the receipt registration unit 351 determines that the OCR operation has failed for the receipt from which the failure location image originates.

If the receipt registration unit 351 determines that the OCR operation has failed, in other words, the entry information has not been acquired, the receipt registration unit 351 outputs to the image forming apparatus 600 information on the receipt from which the entry information has not been successfully acquired.

Specifically, the receipt registration unit 351 outputs to the image forming apparatus 600 the receipt image, entry information (default value), and failure location image of the receipt from which the entry information has not been successfully acquired (step S109).

The failure location image is an example of information on the location where an attempt to acquire the entry information has failed. According to the first exemplary embodiment, the receipt registration unit 351 outputs to the image forming apparatus 600 the information on the location where the attempt to acquire the entry information has been made.

The image forming apparatus 600 has read the receipts serving the acquisition target of the entry information. According to the first exemplary embodiment, the information, such as the failure location image, is output to the image forming apparatus 600 that has read the receipts.

According to the first exemplary embodiment, the receipt image and entry information are output together with the failure location image to the image forming apparatus 600.

According to the first exemplary embodiment, the failure location image is output as the information on the receipt from which the entry information has not been successfully acquired, together with the receipt image and the entry information.

The receipt image as an example of a medium image is an image of the whole receipt. The receipt image is the predetermined default value.

According to the first exemplary embodiment, the information on the receipt from which the entry information has not been successfully acquired is displayed on the display 606 in the image forming apparatus 600 (see FIGS. 4 and 5) (step S110).

Specifically, according to the first embodiment, the receipt image, entry information, and failure location image are displayed on the display 606 as the information on the receipt from which the receipt image has not been successfully acquired.

FIG. 7 illustrates a display example on the display 606 in the image forming apparatus 600.

The display 606 of the first exemplary embodiment displays a receipt image G1, entry information G2, and failure location image G3.

The image forming apparatus 600 acquires the receipt image G1 by reading a receipt and the receipt image G1 represents the whole receipt.

According to the first exemplary embodiment, an image denoted by alphanumeric characters 7A indicates the failure location image G3. The failure location image G3 indicates the location from which the entry information G2 on the receipt (the original correct entry information G2) has not been successfully acquired.

The region of the entry information G2 illustrated in FIG. 7 is not an image but text information acquired by the OCR unit 353C or the default value obtained in the compensation described above.

Specifically, information, such as “total sum,” “date of receipt,” and “day and month” out of the entry information G2 is text information acquired by the OCR unit 353C. Information, such as “$100.00”, out of the entry information G2 is the default value acquired in the compensation.

The entry information G2 compensated for with the default value is displayed at a display location of the failure location image G3.

Specifically, the “total sum” is displayed as an example of amount of money information and the “date of receipt” is displayed as an example of date information in the display location of the failure location image G3. The amount of money “$100.00” displayed in the region of the total sum is not a correct value but a default value.

According to the first exemplary embodiment, the incorrect value is compensated for with the default value and the default value is thus displayed. Alternatively, the default value is not displayed with the region for the default value left blank.

The display 606 displays as a part of the screen a screen G4 that the user uses to input information recorded on the receipt (hereinafter referred to as an “input screen G4”).

In other words, the display 606 in the image forming apparatus 600 displays the input screen G4 that the user uses to input the correct entry information G2.

According to the first exemplary embodiment, the user operates the input screen G4 to input the correct entry information recorded on the receipt (see step 5111 in FIG. 6). In other words, according to the first embodiment, the user corrects the default value acquired by the management server 300.

Specifically, the amount of money is not correct and the user inputs information on the correct amount of money by operating the display 606.

FIG. 7 illustrates a first one of three receipts from which the entry information G2 has not been successfully acquired.

Specifically, according to the first embodiment, the entry information has not been successfully acquired from the three receipts. The screen in FIG. 7 displays the first receipt out of the three receipts from which the entry information has not been successfully acquired.

The user inputs the information on the correct amount of money for the first receipt and selects the portion denoted by alphanumeric characters 7B. In this way, screen shifting is performed to display information on a second receipt.

The user then inputs correct information on the second receipt by operating the display 606.

The user further selects the portion denoted by the alphanumeric characters 7B in FIG. 7. Screen shifting is further performed displaying information on a third receipt.

The user may input the correct information on the third receipt by operating the display 606.

According to the first exemplary embodiment, the information input on the image forming apparatus 600 by the user is transmitted to the management server 300 (see step S112 in FIG. 6) and the management server 300 acquires the input information. In other words, the management server 300 acquires the correct entry information G2 input by the user.

The management server 300 then replaces the incorrect entry information G2 with the correct entry information G2. In other words, the management server 300 replaces the default information with the correct entry information G2.

According to the first exemplary embodiment, the receipt registration unit 351 in the management server 300 transmits to the external server 400 the receipt image G1 and entry information G2 (corrected entry information G2) acquired from each of the receipts (see step S113 in FIG. 6).

In this way, the receipt image G1 and entry information G2 for each of the receipts are registered on the external server 400.

When the entry information G2 is transmitted to the external server 400, the entry information G2 of the receipt from which the entry information G2 has been correctly acquired is transmitted to the external server 400.

Concerning the receipt with the default value replaced with the correct entry information G2, that correct entry information G2 is transmitted to the external server 400.

As described above, the display 606 in the image forming apparatus 600 displays the failure location image G3 as an example of information on the location where an attempt to acquire the entry information G2 has been performed.

The information on the location where an attempt to acquire the entry information G2 has been performed is not limited to the failure location image G3.

The information on the location where an attempt to acquire the entry information G2 has been performed may be a message something like “The amount column of the receipt having the title “ABC” has not been successfully read.”

Another message may be something like “The date column of the third receipt from the top out of the vertically arranged receipts has not been successfully read.”

The information on the location where an attempt to acquire the entry information G2 has been performed is not limited to the failure location image G3 but may be text information as described above.

A determination as to whether the reading of each receipt has been successful may be left to the user by notifying the user of the reading results. In such a case, however, this may be time consuming because the user may be obliged to perform the determination on all the receipts.

According to the first exemplary embodiment, the location where the reading has failed is identified and then notified of the user. The user is thus free from performing the determination on all the receipts and the user workload may be reduced.

According to the first exemplary embodiment, the user inputs the correct information via the image forming apparatus 600 and the user workload may thus be reduced.

In order to re-acquire the entry information G2, the user may set again on the image forming apparatus 600 a receipt from which the entry information G2 has not successfully acquired. In such a case, a target receipt may be selected from multiple receipts and set on the image forming apparatus 600.

In contrast, according to the first exemplary embodiment, the entry information G2 may be re-acquired without setting again the receipt on the image forming apparatus 600. The user workload may thus be reduced.

Second Exemplary Embodiment

The receipts may be processed by using the image forming apparatus 600 and management server 300 in the first exemplary embodiment.

Alternatively, apparatuses processing the receipts are not limited to the image forming apparatus 600 and management server 300.

FIG. 8 illustrates a process that is performed on the receipts by using the user terminal 500.

In the process in FIG. 8, operations in steps S201 through S208 are respectively identical to the operations in steps S101 through S108 in FIG. 6.

Operations in step S209 and thereafter are described below. In the following discussion, the acquisition of the entry information G2 has failed from three receipts.

In step S209, the management server 300 outputs to the image forming apparatus 600 the receipt image G1, the entry information G2, and the failure location image G3 in a similar way as described above.

The screen in FIG. 7 is displayed on the display 606 in the image forming apparatus 600 in a similar way as described above. The information on the receipt from which the entry information G2 has not been successfully acquired is displayed on the display 606 (step S210).

The application running on the user terminal 500 outputs to the user terminal 500 a completion notice indicating the completion of the process (step S215). The user terminal 500 outputs to the user the completion notice indicating the completion of the process (step S216).

The user operates the display 606 in the image forming apparatus 600 and presses an “information update” button (not illustrated) displayed on the display 606 to update information (step S217).

The image forming apparatus 600 accesses the management server 300 and acquires the entry information G2 that the user terminal 500 has acquired through the reading described above (step S218).

Specifically, the image forming apparatus 600 acquires the entry information G2 that is acquired by the user terminal 500 through the analysis and transmitted to the management server 300.

The entry information G2 is displayed on the display 606 in the image forming apparatus 600. In other words, the entry information G2 that has been acquired by taking a close-up picture of the actual receipt using the user terminal 500 is displayed on the display 606 in the image forming apparatus 600 (step S219).

FIG. 10 illustrates the display example on the display 606 in the image forming apparatus 600.

In this example, the entry information G2 that the user terminal 500 has acquired from the three receipts is displayed on the display 606 in the image forming apparatus 600.

The screen on the display 606 is shifted by successively pressing the location denoted by alphanumeric characters 10A. The entry information G2 that the user terminal 500 has acquired for each of the three receipts is displayed.

If any error is found, the user may operate the location denoted by alphanumeric characters 10B and enter correct entry information G2. If a confirm button (not illustrated) is pressed (step S220 in FIG. 8), a confirmation notice is transmitted from the image forming apparatus 600 to the management server 300 (step S221) and the entry information G2 acquired from each of the receipts is confirmed.

According to the second exemplary embodiment, the entry information G2 stored on the management server 300 is transmitted to the external server 400 (step S222).

Referring to FIG. 7, the information on the receipt from which the entry information G2 has not been successfully acquired is output to the image forming apparatus 600.

Alternatively, the information on the receipt from which the entry information G2 has not been successfully acquired may be output to the user terminal 500 as an example of a second reading device different from the image forming apparatus 600.

A screen similar to the screen in FIG. 7 is displayed on the user terminal 500.

The screen similar to the screen in FIG. 7 displayed on the user terminal 500 may have a display layout different from the display layout on the image forming apparatus 600.

When the screen similar to the screen in FIG. 7 is displayed on the user terminal 500, the receipt image G1, entry information G2, and failure location image G3 are displayed on the user terminal 500 in a similar way as described above.

In other words, when the screen similar to the screen in FIG. 7 is displayed on the user terminal 500, the information on the receipt from which the entry information G2 has not been successfully acquired is output to the user terminal 500 and is displayed on the user terminal 500.

In a similar way as described above, the screen on the user terminal 500 displays the receipt image G1 indicating the whole receipt as the information on the receipt from which the entry information G2 has not been successfully acquired.

The screen displayed on the user terminal 500 displays in a similar way as described above the information on the location where an attempt to acquire the entry information G2 has been made. Specifically, the failure location image G3 is displayed in a similar way as described above as the information on the location where the attempt to acquire the entry information G2 has been made.

The screen displayed on the user terminal 500 displays in a similar way as described above the input screen G4 that the user uses to input information recorded on the receipt.

Modifications

In the exemplary embodiments described above, the information on the receipt from which the entry information G2 has not been successfully acquired is output to the image forming apparatus 600 or the user terminal 500.

The information output to the image forming apparatus 600 or the user terminal 500 is not limited to the information on the receipt from which the entry information G2 has not been successfully acquired. The information output to the image forming apparatus 600 or the user terminal 500 may be information on a receipt from which the entry information G2 with the acquired entry information G2 failing to satisfy a specific condition. This information may be referred to as “acquisition entry information G2.”

In other words, the information output to the image forming apparatus 600 or the user terminal 500 may be information on a receipt from which the entry information G2 has successfully been acquired but the acquired entry information G2 fails to satisfy the specific condition.

The receipts may include a receipt from which the entry information G2 has not been successfully acquired and a receipt from which the entry information G2 has been acquired with the acquired entry information G2 failing to satisfy the specific condition.

In such a case, the information output to the image forming apparatus 600 or the user terminal 500 may include the information on the receipt from which the entry information G2 has not been successfully acquired and the information on the receipt from which the entry information G2 has been acquired but the acquired entry information G2 fails to satisfy the specific condition.

When the information on the receipt that has provided the entry information G2 failing to satisfy the specific condition is output, the receipt image G1, entry information G2 (entry information G2 compensated for with the default value), and failure location image G3 (information on the location where the acquired entry information G2 is placed) may be output to the image forming apparatus 600 or the user terminal 500 in a similar way as described above.

Concerning the entry information G2, the entry information G2 acquired from the OCR unit 353C may be output in place of the entry information G2 compensated for with the default value to the image forming apparatus 600 or the user terminal 500.

When the information on the receipt that has provided the entry information G2 failing to satisfy the specific condition is output, the receipt image G1 and the failure location image G3 may be output to the image forming apparatus 600 or the user terminal 500.

In such a case, the entry information G2 is not displayed on the image forming apparatus 600 or the user terminal 500 with the region for the entry information G2 left blank.

In this case as well, the image forming apparatus 600 or the user terminal 500 may be designed to display the input screen G4 in a similar way as described above.

The case “the entry information G2 has not been successfully acquired” is intended to mean that the entry information G2 has not been acquired even if other information, such as numerical values or text, is acquired.

For example, the information, such as the words like the “total sum” and the “date of receipt”, are attached as illustrated in FIG. 7. Even if the “total sum” and the “date of receipt” are acquired, information indicating the numerical numbers placed beside and corresponding to these words may not possibly be acquired. This corresponds to the case that “the entry information G2 has not been successfully acquired.”

The case expressed by the phase “the acquired entry information G2 failing to satisfy the specific condition” means that while the entry information G2 has been acquired but the acquired entry information G2 fails to satisfy the specific condition.

For example, a numerical value may be acquired as the entry information G2 but the number of digits of the numerical value may be more than or less than a predetermined number of digits. Such a case corresponds to the case of “the acquired entry information G2 failing to satisfy the specific condition.”

For example, information other than the numerical value may be acquired in the environment under which the numerical value is available. Such a case corresponds to the case of “the acquired entry information G2 failing to satisfy the specific condition.”

Machine learning may be used to improve the reading accuracy of receipts.

Specifically, to address the improvement of the reading accuracy, machine learning may be successively performed based on images of failure locations and correct information subsequently input by the user. Specifically, each time the user enters correct information, machine learning is performed based on the images of failure locations and the correct information.

In other words, to address the improvement of the reading accuracy, parameters used in reading receipts are modified based on the machine learning results.
