FIG. 2 is an explanatory diagram showing a system example in the case of realizing the present embodiment.
There is a form definition generation system 210, an electronic pen paper printing system 220, and a writing information processing system 230. A printing device 225 is connected to the electronic pen paper printing system 220, and an electronic pen 235 is connected to the writing information processing system 230.
The form definition generation system 210 is a system for generating a form definition, includes a module configuration illustrated in FIG. 12 described later, and performs processing according to the flowchart illustrated in FIG.
The electronic pen paper printing system 220 uses a printing device 225 to print a document on which information images (hereinafter also referred to as dot code images) using the form definition generated by the form definition generation system 210 are superimposed. 1 includes the module configuration illustrated in FIG. 1 or includes the module configuration illustrated in FIG. 14 described later, and performs processing according to the flowchart illustrated in FIG.

In processing related to an electronic pen in an information processing system other than the present embodiment, a form image printed on electronic pen paper or a form definition used when processing writing and a paper ID assigned to the paper The correspondence relationship is determined when a form is printed to create electronic pen paper, and is stored in the information processing system. When processing handwritten information handwritten using an electronic pen, a paper ID is extracted from the written information, and a form image or form definition is extracted by following the information stored in the information processing system.
However, this method cannot be used when the system for printing electronic pen paper and the system for processing writing information are highly independent. For example, this is the case where the system for printing electronic pen paper and the system for processing writing information are different systems, and there is no communication network and they are separated. Even when connected as a communication network, it is necessary to construct a high-cost server system in order for a system that prints electronic pen paper to have a function of providing information to a system that processes writing information. In some cases, it is difficult to apply an information processing system other than the present embodiment.

Note that the form definition generation system 210, the electronic pen paper printing system 220, and the writing information processing system 230 are independent from each other in the example shown in FIG. 2, but via a communication line (wired, wireless, or a mixed line). Some of them (for example, the form definition generation system 210 and the electronic pen paper printing system 220) may be connected by a communication line. In the present embodiment, information in which the form definition generated by the form definition generation system 210 is associated with the form definition identification information is shared.
For example, the sharing method may have the following variations.
(1) A function is provided that allows a corresponding copy of a form definition and form definition identification information to be taken out of the electronic pen paper printing system 220. A function for registering the correspondence between the form definition and the form definition identification information in the writing information processing system 230 is prepared. For example, a corresponding copy of the form definition and the form definition identification information is taken out, copied to a USB memory or the like, and registered in the writing information processing system 230 via the USB memory.
(2) Form definition generation system 210 and electronic pen paper printing system 220 are in a single system (for example, a system in which form definition generation system 210 and electronic pen paper printing system 220 are connected via a communication line). In the case where the coexistence and the writing information processing system 230 are independent, the system configured by the former form definition generation system 210 and the electronic pen paper printing system 220 includes a form definition and form definition identification information. A function is provided that allows a corresponding copy to be taken out of the system, and the latter handwritten information processing system 230 is provided with a function for registering the correspondence between the extracted form definition and form definition identification information. .

FIG. 3 is an explanatory diagram showing an example of the electronic pen paper 310 on which an information image is printed according to the present embodiment. The electronic pen paper 310 is printed by the electronic pen paper printing system 220 using the printing device 225 (print module 130). A dot code image is printed on the electronic pen paper 310. For example, an area 320 in the electronic pen paper 310 is printed with a dot code image as shown in FIG. The dot code image represents the ID (paper ID) assigned to each electronic pen paper 310, the position information (X, Y coordinate values) on the paper, and the form definition ID.
For example, the paper ID is a numerical value in a 32-bit space. In the case of character string notation, it is represented by a hexadecimal character string. Therefore, the range of the paper ID is “00000000” to “FFFFFFFF”. The form definition ID is generally smaller than the number of bits of the paper ID. Further, the total number of bits of the paper ID and the form definition ID may be 32 bits.

FIG. 4 is an explanatory diagram illustrating a configuration example in the electronic pen 235.
An outline will be described. When writing on the electronic pen paper 310 with the electronic pen 235, when the pressure sensor is turned on, a dot code image on the electronic pen paper 310 is picked up, decoded, and the paper ID of the electronic pen paper 310 and the electronic pen paper 310. The upper position information (X and Y coordinate values), paper ID, and form definition ID are extracted and stored in the memory. Then, the information stored in the memory is transmitted to the writing information processing system 230 via the communication circuit. The pen pressure ON information may be stored in the memory as information that the pressure sensor is turned on, and the pen pressure OFF information may be stored as information that the pressure sensor is turned off. Moreover, you may make it include the information regarding the time when each information generate | occur | produced (it may be a year, a month, a day, second, the second or less, or these combination). Further, unreadable information indicating that the decoding could not be performed may be included.

Next, this will be described in detail. As illustrated, the electronic pen 235 includes a control circuit 401 that controls the operation of the entire pen. Further, the control circuit 401 includes an image processing unit 401a that processes a dot code image detected from an input image, and a data processing unit 401b that extracts a paper ID and position information from the processing result.
The control circuit 401 is connected to a pressure sensor 402 that detects a writing operation by the electronic pen 235 by a pressure applied to the pen tip 409. In addition, an infrared LED 403 that irradiates infrared light on the paper and an infrared CMOS 404 that inputs an image are also connected. Further, an information memory 405 for storing paper ID, form definition ID, position information, etc., a communication circuit 406 for communicating with an external device, a battery 407 for driving the pen, and pen identification information (pen A pen ID memory 408 for storing (ID) is also connected.

Here, an outline of the operation of the electronic pen 235 will be described.
When writing with the electronic pen 235 is performed, the pressure sensor 402 connected to the pen tip 409 detects the writing operation. As a result, the infrared LED 403 is turned on, and the infrared CMOS 404 captures an image on the sheet by the CMOS sensor.
Note that the infrared LED 403 is pulse-lit in synchronization with the shutter timing of the CMOS sensor in order to suppress power consumption.
The infrared CMOS 404 uses a global shutter CMOS sensor that can simultaneously transfer captured images. A CMOS sensor having sensitivity in the infrared region is used. In order to reduce the influence of disturbance, a visible light cut filter is disposed on the entire surface of the CMOS sensor. The CMOS sensor captures an image with a period of about 70 fps to 100 fps (frame per second). The image sensor is not limited to a CMOS sensor, and other image sensors such as a CCD may be used.

When the image thus captured is input to the control circuit 401, the control circuit 401 acquires a dot code image from the captured image. Then, it is decoded, and the paper ID, form definition ID, and position information embedded in the dot code image are acquired.
Hereinafter, the operation of the control circuit 401 at this time will be described.
FIG. 5 is a flowchart illustrating an example of processing performed by the electronic pen 235 (control circuit 401).
In step S501, the image processing unit 401a inputs an image.
In step S502, processing for removing noise included in the image is performed. Here, the noise includes variations in CMOS sensitivity, noise generated by an electronic circuit, and the like. What processing is performed to remove noise should be determined according to the characteristics of the imaging system of the electronic pen 235. For example, sharpening processing such as blurring processing or unsharp masking can be applied.
In step S503, the image processing unit 401a detects a dot pattern (dot image position) from the image. For example, the dot pattern portion and the background portion are separated by binarization processing, and the dot pattern can be detected from each binarized image position. When a binarized image contains a lot of noise components, for example, it is necessary to combine a filter process for determining a dot pattern based on the area and shape of the binarized image.

In step S504, the image processing unit 401a converts the detected dot pattern into digital data on a two-dimensional array. For example, on a two-dimensional array, a position where a dot is present is converted to “1” and a position where no dot is present is converted to “0”. The digital data on this two-dimensional array is transferred from the image processing unit 401a to the data processing unit 401b.
Next, in step S505, the data processing unit 401b detects a bit pattern including a combination of two dots illustrated in FIG. 7A from the received digital data. For example, the bit pattern can be detected by moving the boundary position of the block corresponding to the bit pattern on the two-dimensional array and detecting the boundary position so that the number of dots included in the block is two. .
When the bit pattern is detected in this way, in step S506, the data processing unit 401b detects the synchronization code by referring to the type of the bit pattern.
In step S507, the identification code and the position code are detected based on the positional relationship from the synchronization code.
Thereafter, in step S508, the data processing unit 401b decodes the identification code to obtain the paper ID and the form definition ID, and decodes the position code to obtain position information. About an identification code, paper ID and form definition ID are obtained by performing RS decoding processing. On the other hand, for the position code, position information is obtained by comparing the position of the read partial series with the M series used at the time of image generation.

FIG. 6 is an explanatory diagram showing an example of a form image 610 and a form definition 620.
The form definition includes at least a form definition 620 (information indicating a definition related to a field in the form), and a form image 610 may be added. The form definition 620 is information indicating an area to be converted into data in the writing information, and attribute information at the time of data conversion (a format at the time of data conversion, a range of characters used at the time of character recognition, a use dictionary Specified). The form definition 620 includes, for example, an entry field 622 and a check field group 624 (including a check field 626 and a check field 628). Specifically, the form definition 620 is defined by a form definition table 1000, for example. FIG. 10 is an explanatory diagram showing an example of the data structure of the form definition table 1000. The form definition table 1000 includes a form definition ID column 1010 and a plurality of column numbers (the number of columns in the electronic pen paper 310). It is constituted by a column 1020. And column No. In column 1020, column No. In addition to the column 1020, an X column 1021, a Y column 1022, a W column 1023, an H column 1024, a data format column 1025, a used character range column 1026, and a used dictionary column 1027 are included. The form definition ID column 1010 stores information for uniquely identifying the form definition in the present embodiment. Column No. A column 1020 stores information for uniquely identifying a column in the form definition. The X column 1021 stores, for example, the upper left x coordinate of the column (rectangle). The Y column 1022 stores, for example, the upper left y coordinate of the column. The W column 1023 stores the width of the column. The H column 1024 stores the height of the column. The data format column 1025 stores the data format of writing written in the column (for example, characters, check marks, etc.). The used character range column 1026 stores a used range of characters that are written in the column (for example, only English letters, only katakana, etc.). The use dictionary column 1027 stores a dictionary (for example, name dictionary) that is used when recognizing characters that are written in the column. The data format column 1025, the used character range column 1026, and the used dictionary column 1027 are used when recognizing the writing entered in the columns.
The form image 610 is document information to be printed on a sheet, and includes a column border, a column name, and a questionnaire for a questionnaire sheet. The document information does not include an information image.

Next, the electronic document for storing written information will be described. Hereinafter, when simply referred to as an electronic document, it refers to an electronic document for storing written information.

However, the paper ID, form definition ID (hereinafter also referred to as paper ID, etc.) and position information are expressed using 32 (5 bits) of these 36 patterns.
Incidentally, the minimum square shown in FIG. 7A has a size of 2 dots × 2 dots at 600 dpi. Since the size of one dot at 600 dpi is 0.0423 mm, one side of this minimum square is 84.6 μm (= 0.0423 mm × 2). The larger the dots that make up the code pattern, the more likely it is to be noticeable. However, if it is too small, printing with a printer becomes impossible. Therefore, the above-described value larger than 50 μm and smaller than 100 μm is adopted as the dot size. Thereby, it is possible to form dots of an optimum size that can be printed by the printer. That is, 84.6 μm × 84.6 μm is the minimum size that can be stably formed by the printer.
In addition, by making the dot such a size, one side of one bit pattern becomes about 0.5 (= 0.0423 × 2 × 6) mm.
A code pattern composed of such bit patterns will be described.
FIG. 7B shows an example of the arrangement of code patterns.
Here, the minimum square shown in FIG. 7B corresponds to the bit pattern shown in FIG. That is, an identification code obtained by encoding a paper ID or the like is embedded using 16 (= 4 × 4) bit patterns. Also, the X position code obtained by encoding the position information in the X direction and the Y position code obtained by encoding the position information in the Y direction are each embedded using four bit patterns. Further, a synchronization code for detecting the position and rotation of the code pattern is embedded in the upper left corner using one bit pattern.
Since the size of one code pattern is equal to the width of five bit patterns, it is about 2.5 mm. In the present embodiment, a code pattern image obtained by imaging the code pattern generated in this way is arranged on the entire sheet surface.

FIG. 8 is an explanatory diagram showing an example of information encoding processing and an example of information image (dot code image) generation processing in the present embodiment.
First, encoding of a paper ID or the like will be described.
An RS (Reed-Solomon) code of a block coding method is used for coding a paper ID or the like. As described with reference to FIG. 7, in this embodiment, information is embedded using a bit pattern that can represent 5-bit information. Therefore, since an information error also occurs in units of 5 bits, an RS code having good coding efficiency is used in the block coding method. However, the encoding method is not limited to the RS code, and other encoding methods such as a BCH code can also be used.
As described above, in this embodiment, information is embedded using a bit pattern having a 5-bit information amount. Therefore, the block length of the RS code needs to be 5 bits. For this reason, the paper ID and the like are divided into blocks of 5 bits. In FIG. 8, a first block “00111” and a second block “01101” are cut out from the paper ID “0011101101001...”.
Then, RS encoding processing is performed on the blocked paper ID and the like. In FIG. 8, “blk1”, “blk2”, “blk3”, “blk4”,... Are blocked and then RS-encoded.
By the way, in the present embodiment, the paper ID or the like is divided into 16 (= 4 × 4) blocks. Therefore, the number of code blocks in the RS code can be 16.
Further, the number of information blocks can be designed according to an error occurrence state. For example, if the number of information blocks is 8, RS (16, 8) code is obtained. This code can correct even if an error of 4 blocks (= (16−8) / 2) occurs in the encoded information. Moreover, if the position of the error can be specified, the correction capability can be further improved. In this case, the amount of information stored in the information block is 40 bits (= 5 bits × 8 blocks), of which 32 bits are used.

Next, encoding of position information will be described.
For encoding the position information, an M-sequence code, which is a kind of pseudo-random sequence, is used. Here, the M sequence is a sequence of the maximum period that can be generated by a K-stage linear shift register, and has a sequence length of 2K-1. Arbitrary consecutive K bits taken out from the M sequence have a property that they do not appear at other positions in the same M sequence. Therefore, the position information can be encoded by using this property.
By the way, in the present embodiment, a necessary M-sequence order is obtained from the length of position information to be encoded, and an M-sequence is generated. However, if the length of the position information to be encoded is known in advance, it is not necessary to generate the M sequence each time. That is, a fixed M sequence may be generated in advance and stored in a memory or the like.
For example, it is assumed that an M sequence (K = 13) having a sequence length of 8191 is used.
In this case, since the position information is also embedded in units of 5 bits, 5 bits are extracted from the M series having a sequence length of 8191 and blocked. In FIG. 8, the M sequence “11010011011010...” Is divided into blocks of 5 bits.

  As described above, in the present embodiment, different encoding methods are used for the position information and the paper ID. This is because it is necessary to set the detection capability such as the paper ID so as to be higher than the detection capability of the position information. That is, since the position information is information for acquiring the position of the paper surface, even if there is a part that cannot be decoded due to noise or the like, the part is lost and does not affect the other part. On the other hand, when the paper ID or the like fails to be decrypted, it is impossible to detect the target reflecting the written information. Further, with this configuration, it is possible to minimize the image reading range when the position information and the paper ID are decoded. That is, if an encoding method having a boundary such as an RS code is used for position information, it is necessary to read the code between the boundaries when decoding it, so the range for reading the image is shown in FIG. The area needs to be twice as large as the area. However, by using the M series, it is possible to have a configuration in which an area having the same size as the area shown in FIG. This is because the position information can be decoded from an arbitrary partial sequence of the M sequence due to the nature of the M sequence. That is, when decoding the paper ID and the position information, it is necessary to read the area having the size shown in FIG. 7B, but the read position coincides with the boundary shown in FIG. 7B. There is no need to let them. The position information can be decoded from a partial series at an arbitrary position of the M series. For the paper ID and the like, the same information is arranged on the entire surface of the paper. Therefore, even if the reading position deviates from the boundary shown in FIG. 7B, the original information is restored by rearranging the read information pieces. can do.

As described above, after a paper ID or the like is divided into blocks, it is encoded with an RS code, and when position information is encoded with an M sequence and then divided into blocks, the blocks are synthesized as shown in the figure. Is done. That is, these blocks are developed on a two-dimensional plane in the format shown in the figure. The format shown in FIG. 8 corresponds to the format shown in FIG. That is, a black square means a synchronization code.
Further, “1”, “2”, “3”, “4”,... Arranged in the horizontal direction represent X position codes, and “1”, “2”, “3”, “ 4 ”,... Mean Y position codes. The position code is indicated by a number corresponding to the coordinate position because different information is arranged if the position of the paper is different. On the other hand, the shaded squares represent the identification codes. Since the same information is arranged even if the position of the sheet is different, the identification codes are all indicated by the same mark.
By the way, as can be seen from the figure, there are four bit patterns between two synchronization codes. Therefore, 20 (= 5 × 4) -bit M-sequence partial sequences can be arranged. If a 13-bit partial sequence is extracted from the 20-bit partial sequence, it is possible to specify which partial sequence in the whole (8191) the 13 bits are. As described above, when 13 bits out of 20 bits are used for specifying the position, it is possible to detect or correct the extracted 13-bit error using the remaining 7 bits. That is, it is possible to detect and correct errors by confirming 20-bit consistency using the same generator polynomial as that used when generating the M-sequence.
Thereafter, the bit pattern in each block is imaged by referring to the dot image. Then, an output image representing information with dots as shown on the rightmost side of FIG. 8 is generated.

FIG. 9 is an explanatory diagram showing an example of the data structure of the electronic document management table 910.
FIG. 9 shows an example of a table for managing electronic documents printed on each sheet.
As shown in the figure, the electronic document management table 910 has an identification information column 912, a form definition ID column 914, a print parameter column 916, and a writing information column 918.
The identification information in the identification information column 912 is a paper ID.
The form definition ID column 914 includes the form definition ID of the form definition used when the electronic document printed on each sheet is printed.
The print parameters in the print parameter column 916 are print parameters set when the electronic document is printed on each sheet. In the figure, the print parameters are shown in the form of “page (P), margins (A, B, C, D)”. P is a page number, and A, B, C, and D are left, right, upper, and lower margins (unit: mm), respectively. Here, the page and the margin are shown as the print parameters, but the present invention is not limited to this. In addition to this, it is possible to manage various printing parameters used in normal printing.
The writing information column 918 includes writing information superimposed on each electronic document. The writing information is data for each stroke of the electronic pen 235, and the writing information of one stroke is a column of (X coordinate, Y coordinate).

The electronic document management table 910 shown in the example of FIG. 9 will be described more specifically.
First, the first and second lines indicate that one sheet of paper has been printed based on the form definition indicated by the form definition ID: 0010111. The document of form definition ID: 0010111 consists of two pages, and the left, right, top and bottom margins are printed with 1 mm. The third and fourth lines indicate that one sheet of paper has been printed based on the form definition indicated by the form definition ID: 0010012. The document of form definition ID: 0010012 consists of two pages, and the left, right, top and bottom margins are printed with 2 mm.

  FIG. 12 is a conceptual module configuration diagram of a configuration example of the form definition generation system. The form definition generation system 210 includes a form definition generation module 1210 and a form definition identification information generation module 1220. The form definition generation module 1210 generates the form definition 620 illustrated in FIG. For example, the form definition 620 is generated based on the operator's operation on the keyboard or the like. Specifically, the column No. of the form definition table 1000 illustrated in FIG. A column 1020 group is generated. Note that the form image 610 illustrated in FIG. 6A may also be generated. The form definition identification information generation module 1220 generates a form definition ID that can uniquely identify the form definition 620 generated by the form definition generation module 1210. The form definition ID generated by the form definition identification information generation module 1220 is passed to the form definition identification information reception module 100, and the form definition generated by the form definition generation module 1210 is transferred to the form definition reception module 110.

FIG. 13 is a flowchart illustrating an example of processing performed by the form definition generation system 210.
In step S1302, the form definition identification information generation module 1220 receives the form definition and the number of form definition IDs assigned to the form definition. Note that the number of form definition IDs may be received by an operation such as a keyboard by an operator such as an administrator, or a predetermined number may be received. The operator need not be aware of the number of form definition IDs, and the form definition identification information generation module 1220 may count the number of form definitions generated by the form definition generation module 1210.
In step S1304, the form definition identification information generation module 1220 determines whether or not a form definition ID space having a size sufficient for allocation exists. If there is, the process proceeds to step S1306, and otherwise the process ends. (Step S1398).
In step S1306, the form definition generation module 1210 generates a form definition.
In step S1308, the form definition generation module 1210 and the form definition identification information generation module 1220 transmit the form definition and the form definition ID to the electronic pen paper printing system 220.

FIG. 14 is a conceptual module configuration diagram of an exemplary configuration of the electronic pen paper printing system 220.
The electronic pen paper printing system 220 includes a print instruction reception module 1410, a print information generation module 1420, a form definition management module 1430, a paper ID management module 1440, and a form definition registration module 1450, and is connected to the printing apparatus 225. Yes.
The print instruction reception module 1410 specifies a form definition to be printed as electronic pen paper among the form definitions managed by the form definition management module 1430, and receives an instruction for the number of copies. This instruction may be performed by an operation of the operator's keyboard or the like, or may be a predetermined instruction.

The print information generation module 1420 generates an information image which is an image indicating a paper ID and position information for printing on paper. Then, the generated information image is superimposed on the document information to generate an image for printing.
Specifically, the print information generation module 1420 creates print information based on the instruction received by the print instruction reception module 1410. For the print information, a dot code image composed of unused paper ID groups assigned to the form definition is added to the image information of the form definition included in the form definition designated by the print instruction receiving module 1410. It is a superposition. The paper ID information used when generating the print information is attached with a flag indicating that it has been used. The paper IDs to be assigned are preferably assigned in ascending order or descending order in order to facilitate management of information on the used paper IDs.
The printing apparatus 225 prints the image generated by the print information generation module 1420 on paper.

The form definition management module 1430 stores a plurality of form definitions. Then, by newly generating the form definition, it also manages which part of the form definition ID space is consumed.
The paper ID management module 1440 manages which part of the paper ID space is consumed by printing.
The form definition registration module 1450 registers a new form definition in the form definition management module 1430.

FIG. 15 is a flowchart illustrating an example of processing performed by the electronic pen paper printing system 220.
In step S1502, the print instruction reception module 1410 receives an instruction for a form definition, a form definition ID, and the number of copies to be printed.
In step S1504, the print information generation module 1420 determines whether or not an unused paper ID remains in the paper ID space. If it remains, the process advances to step S1506. Otherwise, the process ends. (Step S1598).
In step S1506, the print information generation module 1420 determines whether or not processing for the number of copies has been completed. If not, the process proceeds to step S1508. Otherwise, the process proceeds to step S1512.
In step S1508, the print information generation module 1420 assigns an unused paper ID among the paper ID groups assigned to the form definition specified in the image information, and generates a dot generated from the coordinates, the paper ID, and the form definition ID. Print information is created by superimposing the code image on the image information.
In step S1510, the print information generation module 1420 sends the print information to the printing apparatus 225. The printing device 225 prints this print information on a sheet.
In step S1512, the form definition registration module 1450 registers the usage status of the paper ID. That is, a flag is set so that the paper ID used in step S1508 cannot be used in the future.

FIG. 16 is a conceptual module configuration diagram of a configuration example of the present embodiment, and illustrates an example of a module configuration in the writing information processing system 230. That is, writing is performed on the paper printed by the printing apparatus 225 with the electronic pen 235, and writing information relating to the writing is received and processed.
Writing information reception module 1600, determination (A) module 1610, document storage module 1615, determination (B) module 1620, writing information storage module 1622, definition information storage module 1624, definition information extraction module 1630, document generation module 1640, superposition module 1650 and an output module 1660.

  The writing information reception module 1600 is connected to the determination (A) module 1610. The writing information reception module 1600 is a form for identifying writing on a sheet on which document information is printed, sheet identification information (paper ID) that is information for identifying the sheet, and form definition that is a definition regarding a column in the sheet. Definition identification information (form definition ID) is accepted as writing information. Specifically, information decoded from an image read by the electronic pen 235 is received.

The determination (A) module 1610 is connected to the writing information reception module 1600, the document storage module 1615, and the determination (B) module 1620. The determination (A) module 1610 determines whether or not a document corresponding to the paper identification information in the writing information received by the writing information receiving module 1600 can be extracted. If it is determined that the document corresponding to the paper identification information can be taken out, the process moves to the superposition module 1650, and the process of superimposing the writing information on the electronic document is performed as described above.
The document storage module 1615 is connected to the determination (A) module 1610 and the superposition module 1650. The document storage module 1615 stores the correspondence between the paper identification information and the electronic document. Specifically, the electronic document management table 910 illustrated in FIG. 9 is stored.

  The determination (B) module 1620 is connected to the determination (A) module 1610, the writing information storage module 1622, the definition information storage module 1624, and the definition information extraction module 1630. If it is determined by the determination (A) module 1610 that the determination (B) module 1620 cannot extract, the determination (B) module 1620 determines whether or not the form definition corresponding to the form definition identification information can be extracted from the definition information storage module 1624. It is determined whether or not the form definition identification information is generated by the form definition generation system 210.

If the determination (B) module 1620 determines that it cannot be taken out, the writing information received by the writing information receiving module 1600 may be controlled to be stored in the writing information storage module 1622. At the time when the processing by the writing information processing system 230 is performed, if the information corresponding to the paper identification information in the writing information is not stored in the definition information storage module 1624, the writing information is stored. For example, when the form definition / form image correspondence table 1100 illustrated in FIG. 11 and the form definition table 1000 illustrated in FIG. 10 have not yet been generated, or the form definition / form image correspondence table 1100 and form definition table 1000 are generated. However, the definition information storage module 1624 may not be stored yet.
Then, the decision (B) module 1620, when a new combination of form definition identification information and form definition is stored in the definition information storage module 1624, identifies the form definition in the writing information stored in the writing information storage module 1622. It may be determined whether or not the form definition associated with the information can be extracted from the definition information storage module 1624. For example, when the form definition / form image correspondence table 1100 and the form definition table 1000 that have already been generated are stored in the definition information storage module 1624, or the form definition / form image correspondence table 1100 and the form definition table 1000 are generated. This corresponds to the case of being stored in the definition information storage module 1624.

The definition information storage module 1624 is connected to the determination (B) module 1620 and the definition information extraction module 1630. The definition information storage module 1624 stores form definition identification information and form definitions in association with each other. Specifically, the form definition / form image correspondence table 1100 illustrated in FIG. 11 and the form definition table 1000 illustrated in FIG. 10 are stored.
The writing information storage module 1622 is connected to the determination (B) module 1620. The writing information storage module 1622 stores writing information when it is determined by the determination (B) module 1620 that it cannot be taken out.

The definition information extraction module 1630 is connected to the determination (B) module 1620, the definition information storage module 1624, and the document generation module 1640. If the definition information extraction module 1630 determines that it can be extracted by the determination (B) module 1620, the definition information extraction module 1630 extracts the form definition corresponding to the form definition identification information from the definition information storage module 1624.
The document generation module 1640 is connected to the definition information extraction module 1630 and the superposition module 1650. The document generation module 1640 generates a document based on the form definition extracted by the definition information extraction module 1630. A document may be generated using not only the form definition 620 but also the form image 610.
The superposition module 1650 is connected to the document generation module 1640, the output module 1660, and the document storage module 1615. The superposition module 1650 superimposes the writing in the writing information received by the writing information reception module 1600 on the document generated by the document generation module 1640 and then registers the document in the document storage module 1615. Specifically, the superposition or superposition here refers to adding the target writing as writing information of the corresponding electronic document in the electronic document management table 910.

  The output module 1660 is connected to the polymerization module 1650. The output module 1660 outputs the document (document to which writing is added) generated by the superposition module 1650. Outputting a document includes, for example, printing on a printing device such as a printer, displaying on a display device such as a display, transmitting an image on an image transmission device such as a fax, and an image to an image storage device such as an image database. And handing it over to another information processing apparatus (for example, an information processing apparatus that analyzes writing information).

FIG. 17 is a conceptual module configuration diagram of a configuration example of the writing information processing system 230.
The writing information processing system 230 includes a writing information reception module 1710, a writing information processing module 1720, an electronic document management module 1730, an electronic document display module 1740, an electronic document generation module 1750, a form definition registration module 1760, and a form definition management module 1770. doing. The writing information receiving module 1710 corresponds to the writing information receiving module 1600 described above. The writing information processing module 1720 corresponds to the above-described determination (A) module 1610, determination (B) module 1620, and superposition module 1650. The electronic document management module 1730 corresponds to the document storage module 1615 described above. The electronic document display module 1740 corresponds to the output module 1660 described above. The electronic document generation module 1750 corresponds to the definition information extraction module 1630 and the document generation module 1640 described above. The form definition registration module 1760 causes the form definition management module 1770 to store the correspondence between the form definition ID and the form definition. The form definition management module 1770 corresponds to the definition information storage module 1624 described above.

The writing information processing system 230 is a system that extracts writing information from the electronic pen 235, processes and manages the writing information.
The writing information captured by the writing information processing system 230 is merged with the electronic document corresponding to the electronic pen paper on which writing is performed, and stored in the electronic document management module 1730. Here, merging means writing (superimposing) writing on an electronic document. That is, the writing performed on the physical electronic pen paper is also performed on the electronic document corresponding to the electronic pen paper. Specifically, the writing information is added to a portion (writing information column 918) corresponding to the electronic document in the electronic document management table 910.
Other functions include calling up an electronic document stored in the electronic document management module 1730 and displaying its contents, and recognizing handwritten characters in the electronic document and converting it into text data. Is possible.

In step S1812, the definition information extraction module 1630 extracts the form definition corresponding to the form definition ID determined in step S1810 from the definition information storage module 1624, and the document generation module 1640 uses the form definition. Then, an electronic document having a paper ID included in the writing information is created. An electronic document may be created using a form image using the form image ID column 1120 of the form definition / form image correspondence table 1100.
In step S1814, the determination (B) module 1620 accumulates the writing information storage module 1622 as writing information that cannot be assigned to the electronic document.

In step S1816, the superposition module 1650 merges the writing information into the electronic document (the electronic document extracted in step S1808 or the electronic document created in step S1812) and registers it in the document storage module 1615.

  FIG. 19 is a flowchart illustrating an example of processing performed by the writing information processing system 230. When a new form definition is registered, this flowchart determines whether or not the writing information managed in the writing information storage module 1622 as unassignable writing information corresponds to the new form definition. In the case, a new electronic document is generated and the writing information is merged with the document.
