The scanner I / F217 connects the scanner 222 and the control unit 210. The scanner 222 reads an image on a document to generate image data (that is, scanned image data), and inputs the image data to the control unit 210 via the scanner I / F 217. The MFP 101 can print the image data generated by the scanner 222 by the printer 221 as well as send a file or send an e-mail.

The modem I / F 218 is an interface for connecting the modem 223 and the control unit 210. The modem 223 performs facsimile communication of image data with a facsimile machine (not shown) via a PSTN (Public Switched Telephone Network) 110. The network I / F 219 is an interface for connecting the control unit 210 (that is, the MFP 101) to the network 100. The MFP 101 uses the network I / F 219 to transmit image data and information to an external device (file server 102, etc.) on the network 100, and to receive various information.

The file server 102 is an example of an external server that stores and manages an electronic document file. The file server 102 has a control unit 310. The control unit 310 controls the operation of the entire file server 102. The CPU 311 reads out the control program stored in the ROM 312 and executes various control processes. The RAM 313 is used as a temporary storage area for the main memory, work area, etc. of the CPU 311. The HDD 314 stores image data and various programs.

The network I / F315 is an interface for connecting the control unit 310 (that is, the file server 102) to the network 100. The file server 102 transmits and receives various information to and from other devices on the network 100 via the network I / F 315.

FIG. 2 is a software configuration diagram of the MFP 101 according to the present embodiment. The software of the MFP 101 can be roughly divided into two, a native function unit 410 and an additional application 420. Each part included in the native function part 410 is provided as standard in the MFP 101. On the other hand, the additional application 420 is an application additionally installed on the MFP 101. The additional application 420 is an application based on Java (registered trademark), and can easily realize the addition of functions to the MFP 101. Other additional applications (not shown) may be installed in the MFP 101.

The application display unit 423 displays a UI (User Interface) screen for receiving operations, inputs, and instructions by the user on the liquid crystal display unit having the touch panel function of the operation unit 220 of the MFP 101. The details of the UI screen will be described later.

The scan instruction unit 421 receives information from the user input via the application display unit 423, and requests the scan unit 411 to perform a scan process together with the scan settings and transfer settings included in the input information. Further, the application transfer unit 424, which will be described later, temporarily stores the information of the folder path of the file server 102, which is the transfer destination of the image data.

The scan unit 411 receives a scan request including scan settings from the scan instruction unit 421 and executes a scan process. The scanning unit 411 reads the original by the scanner 222 via the scanner I / F 217 to generate image data, and passes the image data and the transfer setting to the transfer unit 412.

The transfer unit 412 transfers the image data received from the scan unit 411 according to the transfer setting also received from the scan unit 411. As the image data transfer destination, a file server 102, a PC on the network 100 (not shown), or the like can be set. In this embodiment, it is assumed that all the image data generated by the scanning unit 411 is once set to be transferred to the additional application 420. Further, the transfer unit 412 has an FTP (File Transfer Protocol) client function, and can transfer image data by FTP to an application receiving unit 422 having an FTP server function.

The application receiving unit 422 receives the image data internally transferred from the transfer unit 412 and passes it to the application transfer unit 424.

The application transfer unit 424 passes the received image data to the image analysis unit 425.

The image analysis unit 425 can determine the character string area, divide the character string area, recognize the character string, and the like with respect to the image data. The image analysis unit 425 compares the determined character string area with the character string area of the form information stored in the form information holding unit 428, and based on similar form information, information related to the image data (for example, for example. It is possible to extract the character string area information used for setting (file name, etc.). The image analysis unit 425 passes the character string area information extracted from the image data to the application transfer unit 424.

Further, the application transfer unit 424 passes the received image data, the extracted character string area information, and the selection information of the character string area selected by the user to the application display unit 423.

The application display unit 423 passes the image data, the character string area information, and the selection information received from the application transfer unit 424 to the preview display unit 426.

The preview display unit 426 displays a UI screen related to file name setting for receiving operations, inputs, and instructions by the user on the liquid crystal display unit having the touch panel function of the operation unit 220. The details of the UI screen to be displayed will be described later.

The upload instruction unit 427 displays a UI screen related to the folder path setting on the liquid crystal display unit of the operation unit 220. The details of the UI screen related to the folder path setting will be described later. Further, the upload instruction unit 427 receives the folder path input on the UI screen and passes it to the application transfer unit 424.

Further, the application transfer unit 424 adds the character string received from the preview display unit 426 as a folder or file name to the folder path received by the upload instruction unit 427. Then, the application transfer unit 424 transfers (transmits) the image data to the file server 102.

When the transfer is completed, the application transfer unit 424 notifies the application display unit 423 that the transfer is completed. The application display unit 423 updates the display content in response to the notification from the application transfer unit 424.

Further, the application transfer unit 424 has an SMB (Server Message Block) client function. As a result, the application transfer unit 424 can perform file and folder operations on the file server 102 having the SMB server function by using the SMB. In addition to SMB, WebDAV (Distributed Instruction and Versioning protocol for the WWW), FTP (File Transfer Protocol), or the like may be used. Moreover, you may use SMTP (Simple Mail Transfer Protocol) or the like. In addition, SOAP (Simple Object Access Protocol), REST (Representational State Transfer), and the like can be used for purposes other than file transmission.

FIG. 3 is a flowchart showing a process in which the MFP 101 generates scan image data and uploads it to the file server 102. Each operation (step) shown in the flowchart is realized by the CPU 211 of the MFP 101 reading and executing the control program stored in the HDD 214.

Hereinafter, an example in which the flowchart of FIG. 3 is performed three times will be described. In the first implementation, a process in which the form information holding unit 428 performs the scanning process in a state where the similar document information of the document to be scanned is not held will be described. Subsequently, in the second implementation, the case where the form information holding unit 428 retains the document information of the first implementation and scans a document similar to the document scanned in the first implementation will be described. Therefore, in the second implementation, appropriate character information is acquired from the scanned image data by using the document information held in the form information holding unit 428. Then, in the third implementation, a document similar to the document of the first implementation is scanned, but the processing in the case where two adjacent character string areas are determined as one character string area in the scanned image data will be described. do.

<First implementation>
First, the first process will be described with reference to FIG.

In step S301, the application display unit 423 displays the scan setting screen on the liquid crystal display unit of the operation unit 220. The user sets the scan process to be performed by the scan unit 411 via the displayed scan setting screen.

FIG. 4 shows an example of the scan setting screen 400 according to the present embodiment. The scan setting screen 400 has five scan setting buttons 401 to 405. The [Color setting] button 401 accepts a color or monochrome setting at the time of document scanning. The [Resolution setting] button 402 accepts the resolution setting at the time of document scanning. The [Double-sided scanning setting] button 403 accepts the double-sided scanning setting at the time of document scanning. The [Original mixed loading setting] button 404 accepts a setting for whether or not to scan documents of different sizes at the same time when scanning the originals. The [Image Format Setting] button 405 accepts the image format of the scanned image data. When the user makes a setting using these scan setting buttons 401 to 405, candidate setting items are displayed within the range supported by the MFP 101. The user selects a desired setting item from the displayed candidates. The above-mentioned setting buttons are an example, and all of these setting buttons may not exist, or setting buttons other than these may exist. The user can make detailed settings for the scan process through such a scan setting screen 400. The [Cancel] button 406 is a button used to cancel the scan setting. The [scan start] button 407 is a button for instructing the start of the scan process for the document set on the platen or the like.

In step S302, the application display unit 423 determines whether the [scan start] button 407 is pressed or the [cancel] button 406 is pressed. When it is determined that the [scan start] button 407 is pressed, the application display unit 423 causes the scan instruction unit 421 to execute the scan process with the settings selected by the scan setting buttons 401 to 405. When it is determined that the [Cancel] button 406 is pressed, the process ends.

In step S303, the scan instruction unit 421 instructs the scan unit 411 to perform a scan process and scans the document. The scanned image data generated by scanning the original is internally transferred by FTP to the application receiving unit 422 through the transfer unit 412 in step S304.

In step S305, the image analysis unit 425 performs image analysis (layout analysis processing and OCR processing) of the scanned image data according to the instruction from the application receiving unit 422. The image analysis unit 425 analyzes the layout of the scanned image data such as a character string area and a graphic area by, for example, extracting a histogram of the scanned image data or extracting a block of pixels. The character string area is an area (image area) presumed to be a character string. The character string area also includes an area of one character.

FIG. 5 is a flowchart showing the details of the image analysis process in step S305.

In step S501, the image analysis unit 425 reads the scanned image data received from the application receiving unit 422 into a form that can be analyzed.

In step S502, the image analysis unit 425 corrects the read scanned image data to a state in which area determination and character string analysis are easy. Specifically, the image analysis unit 425 corrects the tilt of the scanned image so that the tilt of the document displaced at the time of scanning disappears, or detects the direction of the document and rotates the scanned image.

In step S503, the image analysis unit 425 analyzes the scanned image data corrected in step S502 to determine a character string area, and extracts information on the character string area (hereinafter referred to as character string area information). Table 1 shows an example of character string area information.

In Table 1 above, [number] is a number uniquely indicating each specified character string area. In this example, serial numbers from 1 to 9 are assigned in the order in which they are recognized. [Area X coordinate] indicates the X coordinate of the upper left corner of each specified character string area. [Y coordinate of area] indicates the Y coordinate of the upper left corner of each specified character string area. Hereinafter, when the term "coordinates" is used with respect to the character string area, it means the position coordinates of the upper left corner of the character string area unless otherwise specified. [Area width] indicates the distance from the left side to the right side of each specified character string area. [Area height] indicates the distance from the upper side to the lower side of each specified character string area. In the present embodiment, the [X coordinate of the area], the [Y coordinate of the area], the [width of the area], and the [height of the area] are all indicated by pixels, but may be indicated by points, inches, or the like. The character string area information shall be acquired in the CSV or XML format, but other formats may be used.

In step S504, the image analysis unit 425 compares the character string area information extracted in step S503 with the character string area information of each form information stored in the form information holding unit 428 by the process of step S318 described later. That is, the image analysis unit 425 determines whether or not a similar document has been processed in the past. The image analysis unit 425 is necessary to restore the selected character string area previously selected by the user in the similar document processed in the past on the scanned image data (scanned image data to be processed) obtained by scanning this time. Information (hereinafter referred to as restoration information) is generated. The selected character string area is a character string area selected by the user by the processing of step S308 described later in the past similar manuscript processed before. Restoration of the selected character string area means that the character string area specified based on the restoration information is selected in advance when the preview screen of step S307 described later is displayed, and the character string included in the character string area is scanned this time. It is to be set as information related to image data. For example, the character string included in the specified character string area can be applied to the file name of the scanned image data this time. Hereinafter, in the present embodiment, a file name will be described as an example of information related to the scanned image data.

FIG. 6 is a flowchart showing the details of the restoration information generation processing of the selected character string area in step S504.

In step S601, the image analysis unit 425 compares the character string area information extracted in step S503 with the character string area information of each form information stored in the form information holding unit 428, and similar form information exists. Determine if you want to. In the first implementation, since the form information (that is, the character string area information of the manuscript processed in the past) is not stored in the form information holding unit 428, it is determined as No in step S602, and the restoration information generation process is terminated. That is, the image analysis unit 425. The process ends without generating the restore information of the selected character string area. Then, the process proceeds to step S306 of FIG. Other processes described in FIG. 6 (that is, the processes of steps S603 to S605) will be described later.

In step S306, the application transfer unit 424 acquires the character string area information extracted by the image analysis unit 425 in step S503. The application transfer unit 424 may allow the image analysis unit 425 to acquire the character string area information once stored in the HDD 214.

In step S307, the preview display unit 426 displays the preview screen on the liquid crystal display unit of the operation unit 220 by using the scanned image data and the character string area information acquired from the application transfer unit 424 via the application display unit 423. The user can input information related to the scanned image data (for example, a file name of the scanned image data) via the preview screen.

FIG. 8 shows an example of the preview screen 800. The preview screen 800 has a file name display area 801 for the scanned image data, a button 802 for setting the file name format, and a preview display area 810 for previewing the scanned image data. It also has a [Back] button 830 and a [Next] button 831.

The preview display area 810 includes buttons 811 to 814 for displaying the scanned image data and changing the display state of the scanned image data, and character string areas 815 to 823.

When the [Scroll at the top of the screen] button 811 is selected (touched) by the user, the preview display unit 426 scrolls the area of the scanned image data displayed in the preview display area 810 upward. When the [Scroll at the bottom of the screen] button 812 is selected (touched) by the user, the preview display unit 426 scrolls the area of the scanned image data displayed in the preview display area 810 downward. When the [Screen Enlargement] button 813 is selected (touched) by the user, the preview display unit 426 enlarges and displays the area of the scanned image data displayed in the preview display area 810. When the [Screen reduction] button 814 is selected (touched) by the user, the preview display unit 426 reduces and displays the area of the scanned image data displayed in the preview display area 810.

The preview display unit 426 displays the character string areas 815 to 823 in the preview display area 810 according to the character string area information acquired by the image analysis unit 425. As shown in Table 1 above, the character string area information indicates the position of the character string area on the scanned image data. The character string areas 815 to 823 are displayed at positions considering scroll positions and enlargement / reduction of the scanned image data according to the character string area information. The character string areas 815 to 823 can be selected by the user. When the user selects any of the character string areas, the preview display unit 426 performs character recognition processing (OCR processing: Optical Character Recognition processing) on the selected character string area. The preview display unit 426 extracts characters (text data) included in the selected character string area (image area) by the character recognition process.

The character recognition process is, for example, a process of recognizing a character (text data) by matching a pixel group included in a character string area with a dictionary registered in advance. Such character recognition processing may take time. Therefore, in the present embodiment, the character recognition process is performed on the character string area desired by the user without sequentially performing the character recognition process on the character string area extracted by the image analysis, thereby speeding up the processing. I am trying to.

The preview display unit 426 sets the character (text data) extracted from the character string area selected by the user in the file name display area 801. When the file name display area 801 is touched (selected), the preview display unit 426 displays a software keyboard (not shown), and the user can edit the file name by operating the software keyboard. be able to.

In the preview screen 800 that is first displayed in the first implementation, as shown in FIG. 8A, none of the character string areas is in the selected state.

Returning to FIG. 3, in step S308, the preview display unit 426 generates a file name of the scanned image data according to the user operation input via the preview screen 800.

FIG. 9 is a flowchart showing the details of the file name generation process in step S308.

In step S901, the preview display unit 426 determines whether or not the user has touched the liquid crystal display unit (that is, the preview screen 800) of the operation unit 220. If it is determined that the touch has been made, the process proceeds to step S902, and the preview display unit 426 acquires the coordinates of the touched position. If it is determined that the touch is not made, the process returns to step S901.

In step S903, the preview display unit 426 determines whether the coordinates of the touched position overlap with the character string area displayed in the preview display area 810. The determination of whether or not they overlap is determined by whether or not the coordinates of the touched positions are within the coordinate areas of the character string areas 815 to 823 in the preview display area 810. If it is determined that they overlap, the process proceeds to step S904, and if it is determined that they do not overlap, the process proceeds to step S909. In step S909, if it is determined that the [Next] button 831 or the [Back] button 830 is pressed, the process ends, the process returns to FIG. 3, and the process proceeds to step S309. On the other hand, if it is determined that the button is not pressed, the process returns to step S901.

In step S904, the image analysis unit 425 performs OCR processing on the character string area where the coordinates of the touched positions overlap, and acquires the character string included in the character string area. The acquired character string is passed to the preview display unit 426 as an analysis result.

In step S905, the preview display unit 426 acquires the file name displayed in the file name display area 801. If nothing is displayed in the file name display area 801, the file name cannot be acquired, and the process proceeds to the next step.

In step S906, the preview display unit 426 adds a delimiter to the end of the file name acquired in step S905. In this embodiment, the underscore (“_”) is used as the delimiter, but other characters may be used. If the file name could not be obtained in step S905, the process proceeds to the next step without adding the delimiter.

In step S907, the preview display unit 426 adds the character string of the character string area acquired as the analysis result in step S904, following the delimiter added in step S906. If the file name cannot be acquired in step S905, the delimiter is not added in step S906, so that the character string acquired in step S904 becomes the first character string as the file name.

In step S908, the preview display unit 426 sets the character string generated in step S907 as the file name in the file name display area 801 and returns to step S909.

In the first implementation, steps S901 to S908 are repeated, and it is assumed that the character string areas 815, 816, and 817 are selected in order. FIG. 8B shows a preview screen 800 in that case. If the character string area selected by the user contains characters that cannot be used in the file name on the transfer destination file server, the preview display unit 426 sets the character string in the file name display area 801. , The corresponding character may be removed. In the preview screen 800 of FIG. 8B, the slash (“/”) included in the character string area 817 is removed. The character string to be removed may be stored in the MFP 101 in advance, or information about the character string may be acquired from an external device.

As described above, the file name generation process in step S308 is performed.

Next, returning to FIG. 3, in step S309, the preview display unit 426 determines the operation content in step S909 described above. Specifically, the preview display unit 426 determines whether the [Next] button 831 is pressed or the [Back] button 830 is pressed in step S909. If it is determined that the [Next] button 831 is pressed, the process proceeds to step S310, and if it is determined that the [Back] button 830 is pressed, the process returns to step S301.

In step S310, the preview display unit 426 acquires the file name set in the file name display area 801. The preview display unit 426 passes the acquired file name to the upload instruction unit 427.

In step S311 the upload instruction unit 427 displays the upload setting screen on the liquid crystal display unit of the operation unit 220. The user can make settings related to external transfer (upload) to the file server 102 to be performed by the application transfer unit 424 via the upload setting screen.

FIG. 10 shows an example of the upload setting screen 1000. On the upload setting screen 1000, the folder path input field 1001 accepts the folder path setting of the file server 102 which is the external transfer destination. When the user taps the folder path input field 1001, the upload instruction unit 427 displays a software keyboard (not shown). The user inputs the folder path in the folder path input field 1001 via the displayed software keyboard. In the example of FIG. 10, the character string “2017_09_10” is input in the folder path input field 1001. Upon receiving the instruction to end the setting of the folder path, the upload instruction unit 427 acquires the set folder path and closes the software keyboard. The folder path may be set from other than the folder path input field 1001. For example, the folder path may be set from the address book held by the MFP 101.

In step S312, the upload instruction unit 427 determines whether the [upload] button 1021 on the upload setting screen 1000 has been pressed or the [back] button 1020 has been pressed. If it is determined that the [upload] button 1021 is pressed, the process proceeds to step S313, and if it is determined that the [back] button 1020 is pressed, the process returns to step S307.

In step S313, the upload instruction unit 427 acquires the file server settings stored in advance in the memory of the HDD 214 or the like. The file server settings include the host name of the file server 102, the origin of the folder path, the user name and the password for logging in to the file server 102. The upload instruction unit 427 passes the acquired file server setting, the folder path setting acquired in step S311, and the file name acquired in step S310 to the application transfer unit 424.

In step S314, the application transfer unit 424 generates a storage destination path for storing the scanned image data. The storage destination path is generated by adding the folder path acquired in step S311 to the host name of the file server 102 and the starting point of the folder path included in the file server settings. As a result, for example, the storage path "\\ server01 \ Share \ 2017_09_10" is generated.

In step S315, the application transfer unit 424 accesses the file server 102. The application transfer unit 424 sends the user name and password included in the file server settings acquired in step S313 to the file server 102, and receives the result of user authentication by the file server 102.

In step S316, the application transfer unit 424 determines whether or not the user authentication is successful (whether or not the file server 102 can be logged in) based on the received user authentication result. If the user authentication is successful, the process proceeds to step S317, and if the user authentication fails, the process ends.

In step S317, the application transfer unit 424 externally transfers (uploads) the scanned image data to the folder indicated by the storage destination path generated in step S314.

In step S318, the image analysis unit 425 uses the character string area information acquired from the scanned image in step S306 and the character string area information (that is, selection information) selected by the user on the preview screen in step S308 as form information. It is stored in the holding unit 428. Table 2 shows an example of the character string area information and the selection information stored in the form information holding unit 428.

In Table 2, [Form No.] is assigned a unique number for each form information to be saved. Since Table 2 shows the first type of form information, "1" is assigned. Further, Table 2 stores the selection information in addition to the character string area information. That is, the selection information is held in association with the scanned image data in which the [form No.] is "1". Further, the selection information represents the order of the character string area selected by the user on the preview screen in step S308. Further, "-" in the selection information indicates that the corresponding character string area has not been selected by the user.

<Second implementation>
Next, the second implementation will be described. In the second implementation, a document similar to the original scanned in the first implementation is scanned, and the above-described processing is performed with reference to the flowchart of FIG. Hereinafter, the processing different from that of the first implementation will be mainly described, and the description of the same processing as that of the first implementation will be omitted. Further, the preview screen for the second implementation will be described with reference to FIG.

Table 3 shows an example of the character string region information extracted from the scanned image data by the image analysis unit 425 in the image analysis process in step S305 of FIG. 3, that is, in step S503 of FIG.

Next, in step S601 of FIG. 6, the image analysis unit 425 compares the character string area information extracted in step S503 with the character string area information of each form information stored in the form information holding unit 428. Then, the image analysis unit 425 determines from each form information the form information having many overlaps in the character string area as the similar form information. Here, it is assumed that the form information shown in Table 2 is stored in the form information holding unit 428. In this case, the difference between the character string area of the form information in which the form number shown in Table 2 is "1" and the character string area shown in Table 3 is only the width of the area of the number "8". The other character string regions are at the same position (X coordinate and Y coordinate) in Table 2 and Table 3 and have the same size (width and height). Therefore, the image analysis unit 425 determines that the form information whose form number is "1" is similar form information (that is, it is determined that a similar form exists). Since it is determined that a similar form exists, it is determined as Yes in step S602, and the process proceeds to step S603. The similarity determination of the form is performed, for example, based on whether or not the ratio (similarity) of the number of overlapping character areas to the total number of character string areas to be compared is equal to or higher than a predetermined threshold value. be able to.

In step S603, the image analysis unit 425 determines a restoration candidate area from the character string area included in the scan image data this time, based on the selection information included in the similar form information. Specifically, the image analysis unit 425 identifies a character string area that most overlaps with the character string area in which the number is stored in the "selection information" in the similar form information in Table 2 among the character string areas shown in Table 3. And determine the restoration candidate area. Here, the character string areas of the numbers "1", "8", and "7" shown in Table 3 most overlap with the character string areas having the selection information "1", "2", and "3" of the similar form, respectively. It is identified as a region (ie, a restoration candidate region).

In step S604, the image analysis unit 425 divides each character string area, which is a restoration candidate area. FIG. 7 is a flowchart showing the details of the character string area division process in step S604.

In step S701, the image analysis unit 425 stores a number in the "selection information" in the character string area in which the restoration candidate area determined in step S603 is not selected in the similar form, that is, in the similar form information in Table 2. Determine if it overlaps with a non-existent string area. In the following, the character string area not selected in the similar form is also referred to as a non-selected character string area (or a non-selected character string area). Specifically, in the image analysis unit 425, the character string areas (that is, restoration candidate areas) of the numbers "1", "8", and "7" shown in Table 3 are the numbers "2" of the similar form shown in Table 2. "To" 6 "and" 9 ", it is determined whether or not it overlaps with the character string area (that is, the non-selected character string area). In the examples of Tables 2 and 3, since the restoration candidate area and the non-selected character string area do not overlap, it is determined as No in the following step S702, the character string area division process is terminated, and the process proceeds to step S605 of FIG. That is, if the restoration candidate area and the non-selected character string area of the similar form do not overlap, the character string area (restoration candidate area) is not divided. The other processes shown in FIG. 7 (that is, the processes of steps S703 and S704) will be described with reference to the third example.

In step S605, the image analysis unit 425 generates the restoration information necessary for restoring the selected character string area. Specifically, character recognition of the restoration candidate area acquired in step S603 is performed. In the first implementation, in step S306, the image analysis unit 425 passed the coordinates and size (that is, character string area information) for each character string area as shown in Table 1 to the application transfer unit 424. On the other hand, in the second implementation, the image analysis unit 425 uses the restoration information shown in Table 4, which is obtained by adding the selection information and the character recognition result (“character string in the area”) to the character string area information, as image analysis data in the application transfer unit. Pass it to 424.

In step S307, the preview display unit 426 displays the preview screen on the liquid crystal display unit of the operation unit 220 by using the scan image data and the character string area information (here, restoration information) acquired from the application transfer unit 424. That is, in the second implementation, the preview display unit 426 displays the preview screen in a state where the character string area previously selected by the user is selected based on the restoration information of the restoration candidate area.

FIG. 11 shows an example of the preview screen 1100 displayed in the second step S307 of the implementation. Similar to the preview screen 800 of FIG. 8, the preview screen 1100 has a file name display area 1101, a format setting button 1102, a preview display area 1110, a [back] button 1130, and a [next] button 1131. Further, the preview display area 1110 includes a [screen upper scroll] button 1111, a [screen lower scroll] button 1112, a [screen enlargement] button 1113, and a [screen reduction] button 1114. Since these buttons are the same as the preview screen 800 of FIG. 8, the description thereof will be omitted. Further, the preview display area 1110 displays the character string areas 1115 to 1123 of the scanned image.

In step S308, the preview display unit 426 performs the file name generation process described above with reference to FIG. As shown in Table 4, the preview display unit 426 acquires the selection information of the character string area and the character recognition result from the image analysis unit 425 in the second implementation. Before accepting the user's operation, the preview display unit 426 performs the processing of steps S901 to S908 assuming that the character string areas corresponding to the selection information "1", "2", and "3" are selected in numerical order. And generate the file name of the scanned image data. In the second implementation, as shown in FIG. 11, the character string areas 1115, 1116, and 1117 used for generating the file name are in the selected state in advance before the user performs the operation. Further, the character strings included in the selected character string areas 1115, 1116, and 1117 are displayed in the file name display area 1101 as the file name of the scanned image data this time. This makes it possible to set an appropriate file name for the scanned image data this time while saving the user the trouble of selecting the character string area.

Since the form similar to the form of the first implementation is the processing target in the second implementation, if there is no change in the character string area used for the file name in the processing of step S308, the character string area information in step S318. Etc. are not saved in the form information holding unit 428. On the other hand, when the character string area used for the file name is changed in step S308, at least the selection information among the information stored in the form information holding unit 428 may be modified.

<Third implementation>
Next, the third implementation will be described. In the third implementation, a document similar to the original in the first implementation is scanned, but unlike the second implementation, the restoration candidate area of the scanned image data to be processed is a non-selection of the past scanned image data. The case where it overlaps with the character string area will be described. Further, also in the third implementation, the above-mentioned processing is performed with reference to the flowchart of FIG. In the following, the processes different from the first and second implementations will be mainly described, and the same processes as the first and second implementations will be omitted. Further, the preview screen for the third implementation will be described with reference to FIG.

Table 5 shows an example of the character string region information extracted from the scanned image data by the image analysis unit 425 in the image analysis process in step S305 of FIG. 3, that is, in step S503 of FIG.

Next, in step S601 of FIG. 6, the image analysis unit 425 compares the character string area information extracted in step S503 with the character string area information of each form information stored in the form information holding unit 428. Then, the image analysis unit 425 determines from each form information the form information having many overlaps in the character string area as the similar form information. Here, it is assumed that the form information shown in Table 2 is stored in the form information holding unit 428. In this case, the image analysis unit 425 determines that the form information in which the form number shown in Table 2 is "1" is similar form information. Since it is determined that a similar form exists, it is determined as Yes in step S602, and the process proceeds to step S603.

In step S603, the image analysis unit 425 determines a restoration candidate area from the character string area included in the scan image data this time, based on the selection information included in the similar form information. Specifically, the image analysis unit 425 identifies a character string area that most overlaps with the character string area in which the number is stored in the "selection information" in the similar form information in Table 2 among the character string areas shown in Table 5. And determine the restoration candidate area. Here, the character string areas of the numbers "1", "8", and "7" shown in Table 5 most overlap with the character string areas having the selection information "1", "2", and "3" of the similar form, respectively. It is identified as a region (ie, a restoration candidate region).

In step S604, the image analysis unit 425 divides each character string area, which is a restoration candidate area. FIG. 7 is a flowchart showing the details of the character string area division process in step S604.

In step S701, the image analysis unit 425 determines whether the restoration candidate area determined in step S603 overlaps with the non-selected character string area of the similar form. Specifically, in the image analysis unit 425, the character string areas (that is, restoration candidate areas) of the numbers "1", "8", and "7" shown in Table 5 are the numbers "2" of the similar form shown in Table 2. "To" 6 "and" 9 ", it is determined whether or not it overlaps with the character string area (that is, the non-selected character string area). In the examples of Tables 2 and 5, the character string area of the number "8" in Table 5 and the character string area of the similar form number "9" overlap (for the overlap of the character string areas, refer to FIG. 12). Will be described later). Therefore, in step S702, the image analysis unit 425 determines Yes and proceeds to step S703.

In step S703, the image analysis unit 425 obtains coordinates (hereinafter, also referred to as division coordinates) for dividing the character string area of the number “8” determined to include the non-selected character string area by the process of step S701. decide. In the example of Table 5, the image analysis unit 425 has the width of the character string area of the similar form number “9” in Table 2 from the right end (X coordinate of the area + the width of the area) of the character string area of the number “8”. The coordinates moved to the left by a minute (that is, 45 pixels) are defined as the division coordinates. That is, in the character string area of the number "8", the division coordinates (X coordinates) are determined by the following equation (1).
Divided coordinates (214) = X coordinates of the area (35) + width (224) -difference (45) ... (1)

When the non-selected character string area is included on the left side of the restoration candidate area, the coordinates moved to the right by the width of the non-selected character string area from the left end of the restoration candidate area may be used as the divided coordinates. Further, depending on the method for determining the character string area performed in step S503, an area for each character may be acquired in addition to the character string area. In that case, instead of using the width of the similar form as it is, the length may be expanded or contracted so as to be the midpoint between the characters.

In step S704, the image analysis unit 425 divides the character string region, which is a restoration candidate region, using the division coordinates determined in step S703. That is, the image analysis unit 425 uses the character string area of the number "8" in Table 5 as an area of X coordinate 35, Y coordinate 166, width 179 (224-45), height 30, and X coordinate 214 and Y coordinate. It is divided into two areas of 166, width 45 and height 30. After performing the division, the image analysis unit 425 updates the width of the character string area of the number "8" in Table 5. Further, the image analysis unit 425 adds the character string area corresponding to the non-selected character string area to Table 5 as the number "9", and ends the process of FIG. 7.

Returning to FIG. 6, in step S605, the image analysis unit 425 generates the restoration information necessary for restoring the selected character string area. Specifically, the image analysis unit 425 performs character recognition of the restoration candidate area (that is, the selected character string area) divided in step S704. In the third implementation, in step S306, the image analysis unit 425 performs character recognition on the restoration candidate area (that is, the selected character string area) after the division processing. The image analysis unit 425 passes the restoration information shown in Table 6 including the selection information and the character recognition result (“character string in the area”) to the application transfer unit 424 as image analysis data.

In step S307, the preview display unit 426 displays the preview screen on the liquid crystal display unit of the operation unit 220 by using the scan image data and the character string area information (here, restoration information) acquired from the application transfer unit 424. That is, in the third implementation, the preview display unit 426 divides the non-selected character string area from the restoration candidate area, and displays the preview screen in a state where the divided restoration candidate area is selected.

FIG. 12 shows an example of the preview screen 1200 for the third implementation. Similar to the preview screen 800 of FIG. 8, the preview screen 1200 has a file name display area 1201, a format setting button 1202, a preview display area 1210, a [back] button 1230, and a [next] button 1231. Further, the preview display area 1210 includes a [screen upper scroll] button 1211, a [screen lower scroll] button 1212, a [screen enlargement] button 1213, and a [screen reduction] button 1214. Since these buttons are the same as the preview screen 800 of FIG. 8, the description thereof will be omitted. Further, the preview display area 1210 displays the character string areas 1215 to 1226 of the scanned image and the overlapping area 1250.

FIG. 12A shows a preview screen 1200 displayed on the liquid crystal display unit of the operation unit 220 by the preview display unit 426 if the area division processing of steps S703 and S704 is not performed. The overlapping area 1250 indicates an area in which the character string areas of the similar form number “9” overlap in the character string area 1216 of the number “8” in Table 5.

FIG. 12B shows a preview screen 1200 after dividing the non-selected character string area from the restoration candidate area. In FIG. 12B, the character string area 1216 of FIG. 12A is divided into two character string areas 1225 and 1226. The character string area 1225 is processed as a selected character string area and displayed in the selected state. Further, the character string area 1226 is processed as a non-selected character string area and displayed in a non-selected state.

In step S308, the preview display unit 426 performs the file name generation process described above with reference to FIG. As shown in Table 6, the preview display unit 426 acquires the selection information of the character string area after the division process and the character recognition result from the image analysis unit 425 in the third implementation. Before accepting the user operation, the preview display unit 426 performs the processes of steps S901 to S908 assuming that the character string areas corresponding to the selection information "1", "2", and "3" are selected in numerical order. , Generate the file name of the scanned image data. In the third implementation, as shown in FIG. 12B, the character string areas 1215, 1225, and 1217 used for generating the file name are selected in advance before the user performs the operation. Further, the character strings included in the selected character string areas 1215, 1225, and 1217 are displayed in the file name display area 1201 as the file name of the scanned image data this time. On the other hand, the character string area 1226 corresponding to the non-selected character string area divided from the restoration candidate area is in the non-selected state. That is, the character string area 1226 is not used as a file name when the preview screen is first displayed. This makes it possible to set an appropriate file name while saving the trouble of selection by the user.

As described above, in the present embodiment, using the character string area information of the form information saved in the first implementation, two adjacent character string areas are determined as one character string area as in the third implementation. In this case, the character string area can be divided and an appropriate file name can be set. However, in a state where similar form information is not stored in the form information holding unit 428, two adjacent character string areas as in the third implementation may be determined as one character string area. In that case, the user selects the character string area and then deletes an unnecessary character string. In this way, when the character string is deleted after the character string area is selected, in the process of step S318, the image analysis unit 425 specifies the area of the deleted character string, and the selected character string area is used. The area of the deleted character string may be divided and saved. That is, when the same document as the third implementation is scanned and the preview screen 1200 shown in FIG. 12A is displayed, when the character string areas 1215, 1216, and 1217 are selected, the file name is "estimate_Tokyo". It is set as "Patent Co., Ltd. _20171015". After that, it is assumed that the user deletes the character string "middle". In that case, the character string area 1216 is divided into an area including the character string "Tokyo Patent Co., Ltd." and an area including the character string "Middle", and the character area information as shown in Table 6 is used as form information. It may be stored in the holding unit 428.

In the present embodiment, the character string extracted by performing the image processing is used as the file name of the scanned image data, but it may be used for other purposes. For example, the telephone number corresponding to the extracted character string may be specified, and the scanned image data may be faxed using the telephone number. Further, the e-mail address corresponding to the extracted character string may be specified, and the scanned image data may be sent by e-mail using the e-mail address.

<Second embodiment>
Next, a second embodiment of the present invention will be described. The difference from the first embodiment described above is the character string area division process (step S604 in FIG. 6) and the preview screen. The details of the character string area division process will be described with reference to the flowchart of FIG. Further, the preview screen in the present embodiment will be described with reference to FIG. The description of other configurations similar to those of the first embodiment will be omitted. In this embodiment, it is assumed that the character string area information shown in Table 2 is stored in the form information holding unit 428.

Table 7 shows an example of the character string region information extracted from the scanned image data by the image analysis unit 425 in the image analysis process in step S305 of FIG. 2, that is, in step S503 of FIG.

Next, in step S601 of FIG. 6, the image analysis unit 425 compares the character string area information extracted in step S503 with the character string area information of each form information stored in the form information holding unit 428. Then, the image analysis unit 425 determines from each form information the form information having many overlaps in the character string area as the similar form information. Here, the image analysis unit 425 has the form No. 2 shown in Table 2. The form information in which is "1" is determined to be similar form information. Since it is determined that a similar form exists, it is determined as Yes in step S602, and the process proceeds to step S603.

In step S603, the image analysis unit 425 determines a restoration candidate area from the character string area included in the scan image data this time, based on the selection information included in the similar form information. Specifically, the image analysis unit 425 identifies a character string area that most overlaps with the character string area in which the number is stored in the "selection information" in the similar form information in Table 2 among the character string areas shown in Table 7. And determine the restoration candidate area. Here, the character string areas of the numbers "1", "8", and "7" shown in Table 7 most overlap with the character string areas having the selection information "1", "2", and "3" of the similar form, respectively. It is identified as a region (ie, a restoration candidate region).

In step S604, the image analysis unit 425 divides each character string area, which is a restoration candidate area. FIG. 13 is a flowchart showing the details of the character string area division process in step S604 in the present embodiment.

In step S1301, the image analysis unit 425 determines whether the restoration candidate area determined in step S603 overlaps with the non-selected character string area of the similar form. Specifically, in the image analysis unit 425, the restoration candidate areas of the numbers "1", "8", and "7" shown in Table 7 are not the numbers "2" to "6" and "9" of the similar form. Determine if it overlaps with the selected character string area. In the examples of Tables 2 and 7, since the restoration candidate area and the non-selected character string area do not overlap, it is determined as No in the following step S1302, and the process proceeds to step S1310. The relationship between the restoration candidate area and the non-selected character string area in the present embodiment will be described later with reference to FIG.

In step S1310, the image analysis unit 425 compares the number of character string areas existing in the peripheral area of the restoration candidate area with the number of character string areas existing in the peripheral area in the similar form information. The peripheral area refers to, for example, an area having a constant width on the left and right of the character string area. Comparing the character string area information in Table 2 and Table 7, the number of character string areas included in the peripheral area of the restoration candidate area of the number "8" shown in Table 7 is one, whereas the peripheral area has one. The number of character string areas of similar forms in Table 2 included is two (character string areas of numbers "8" and "9"). That is, the number of character string areas existing in the peripheral area of the restoration candidate area is decreasing. Therefore, in the following step S1311, it is determined as Yes, and the process proceeds to step S1303. If the number of character string areas does not change, the process ends without dividing the character string area, and the process proceeds to step S605 in FIG. As described above, in the present embodiment, it is determined whether or not the non-selected character string area of the past scanned image data is included in the peripheral area based on the number of character string areas included in the peripheral area of the restoration candidate area. ..

In step S1303, the image analysis unit 425 determines the coordinates for dividing the character string area (that is, the restoration candidate area) of the number "8" determined in step S1311 that the number of character string areas has decreased. In the example of Table 7, the image analysis unit 425 moves the coordinates from the right end of the character string area of the number "8" to the left by the width of the character string area of the similar form number "9" (that is, 45 pixels). Use the division coordinates. The character string area of the number "9" is a character string area in which the number is not stored in the "selection information".

In step S1304, the image analysis unit 425 divides the character string region, which is a restoration candidate region, using the division coordinates determined in step S1303. That is, the image analysis unit 425 uses the character string area of the number "8" in Table 7 as an area of X coordinate 34, Y coordinate 166, width 30 (75-45), height 30 and X coordinate 64 (34 + 30). , Y coordinate 166, width 45, height 30. After performing the division, the image analysis unit 425 updates the width of the character string area of the number "8" in Table 7, and adds the new divided character string area to the table 7 as the number "9".

Returning to FIG. 6, in step S605, the image analysis unit 425 generates the restoration information necessary for restoring the selected character string area. In the present embodiment, in step S306, the image analysis unit 425 performs character recognition on the character string area after the division processing in step S1304, and adds the selection information and the character recognition result to the restored information shown in Table 8. It is passed to the application transfer unit 424 as image analysis data.

In step S307, the preview display unit 426 displays the preview screen on the liquid crystal display unit of the operation unit 220 by using the scan image data and the character string area information (here, restoration information) acquired from the application transfer unit 424. That is, in the present embodiment, the preview display unit 426 divides the non-selected character string area from the restoration candidate area, and displays the preview screen in a state where the divided restoration candidate area is selected.

FIG. 14 shows an example of the preview screen 1400 of the present embodiment. Like the preview screen 800 of FIG. 8, the preview screen 1400 has a file name display area 1401, a format setting button 1402, a preview display area 1410, a [back] button 1430, and a [next] button 1431. Further, the preview display area 1410 includes a [screen upper scroll] button 1411, a [screen lower scroll] button 1412, a [screen enlargement] button 1413, and a [screen reduction] button 1414. Since these buttons are the same as the preview screen 800 of FIG. 8, the description thereof will be omitted. Further, the preview display area 1410 displays the character string areas 1415 to 1423, 1460, 1461 of the scanned image. Further, FIG. 14A shows the peripheral areas 1451 to 1453 of the character string areas 1415 to 1417 and the character string area 1450 existing in the similar form.

FIG. 14A shows a preview screen 1400 displayed on the liquid crystal display unit of the operation unit 220 by the preview display unit 426 if the area division processing of steps S1303 and S1304 is not performed. In FIG. 14A, the character string area 1416 including the character string "Masa Co., Ltd." and the character string "Middle" is selected, and the character string "Masa Gochu Co., Ltd." is the file name. It is applied to the file name set in the display area 1401. Since the character string area 1416 does not overlap with the non-selected character string area of the similar form, it does not become the character string area to be divided by the processing method of the first embodiment described above.

FIG. 14B shows a preview screen 1400 after dividing the non-selected character string area from the restoration candidate area. In FIG. 14B, the character string area 1416 is divided into two character string areas 1460 and 1461. The character string area 1460 is processed as a selected character string area and displayed in the selected state. Further, the character string area 1461 is processed as a non-selected character string area and displayed in a non-selected state. That is, the character string area 1416 is divided because the peripheral area includes the character string area corresponding to the non-selected character string area.

In step S308, the preview display unit 426 performs the file name generation process described above with reference to FIG. In the present embodiment, as shown in Table 8, the preview display unit 426 acquires the selection information of the character string area after the division processing and the character recognition result from the image analysis unit 425. Before accepting the user operation, the preview display unit 426 performs the processes of steps S901 to S908 assuming that the character string areas corresponding to the selection information "1", "2", and "3" are selected in numerical order. , Generate the file name of the scanned image data. In the present embodiment, as shown in FIG. 14B, the character string areas 1415, 1460, and 1417 used for generating the file name are selected in advance before the user performs the operation. Further, the character strings included in the selected character string areas 1415, 1460, and 1417 are displayed in the file name display area 1401 as the file name of the scanned image data this time. On the other hand, the character string area 1461 corresponding to the non-selected character string area divided from the restoration candidate area is in the non-selected state. That is, the character string area 1461 is not used as a file name when the preview screen is first displayed. This makes it possible to set an appropriate file name while saving the trouble of selection by the user.
