Description

  The present invention relates to a character string recognition device for recognizing character string information from image information including a character string image, a program thereof, an image reading device including the character string recognition device, and a dictionary for transmitting dictionary information to the character string recognition device. The present invention relates to an information transmission apparatus and its program.

Currently, a document on which an image including a character string image is formed is digitized as image information (image information including a character string image) by a scanner or the like, and OCR (Optical Character Reading, optical) that recognizes and outputs character information therefrom. Character recognition) technology is widely used.
Further, in Patent Document 1, when image data obtained by reading a document image is transmitted by e-mail, the read image data is converted into an attached file format of the e-mail, and from a sheet on which a text image is formed. There is shown a network facsimile apparatus that transmits an e-mail with the result (character code) of reading an image and character recognition as body data of the e-mail.
In character recognition, character recognition accuracy may be poor due to problems such as poor image quality of image information (poor image quality of the original document to be read), and it is required to further improve character recognition accuracy. .
As an effective means for improving the character recognition accuracy, first, character information (character code) is recognized from a character image, and character string information constituted by the arrangement is dictionary information of words (character strings) prepared in advance. Some characters are recognized using character strings. As a result, character string recognition is performed in relation to one or more characters before and after a single character, so that incorrect character recognition that does not make sense as Japanese is corrected, and character string recognition accuracy is improved. Can be planned.
In this case, the contents of the dictionary information used for correction greatly affect the character string recognition accuracy. Normally, it is considered that the character string recognition accuracy improves as the contents (words) of the dictionary information are enriched. However, as the amount of dictionary information increases, the processing load required for character string recognition increases. Furthermore, as the number of character string (text) fields to be recognized increases, such as text (character strings) in a field related to a specific product group or a field related to a specific specialized technology, the number of character strings that are similar in appearance increases. Different words (character strings) are included in the dictionary information, and it may be possible that the recognition accuracy deteriorates.
On the other hand, for example, in Patent Document 2, various electronic books are prepared in advance, an electronic book corresponding to the electronic book is identified from a word obtained by character recognition based on image information, and included in the specified electronic book. A technique for correcting a misrecognized character by comparing a word group (dictionary information) and a word obtained by character recognition is shown. As a result, the dictionary information (word group) used according to the field of the processing target (the content of the image information to be character recognition) is switched, so that the amount of dictionary information used for each character string recognition is suppressed and the character information is reduced. Column recognition accuracy can be improved.
On the other hand, Patent Document 3 discloses a word related person related to a word or field by specifying the word or field in order to identify a person familiar with knowledge and information in an organization composed of a plurality of people. And the frequency by the person concerned with the word (the past frequency of use of the word or the word corresponding to the field). As a result, it is easy to grasp that a person with high frequency tends to be familiar with the word or field.
Japanese Patent Laid-Open No. 2001-22660 JP 2003-173421 A JP 2002-14971 A

However, in the technique disclosed in Patent Document 2, when an electronic book used as dictionary information is identified from a word (character string) obtained by performing character string recognition once, the original character string recognition is erroneously recognized. There is a problem that appropriate dictionary information (electronic book) is not selected.
Here, it is possible to let the user select the dictionary information to be used, but the user recognizes and inputs the relationship between the contents of the image information to be processed and the related dictionary information each time. This is complicated and the operability is deteriorated.
On the other hand, Patent Document 1 and Patent Document 3 do not show any technology related to improving the accuracy of character string recognition (technology related to switching dictionary information in accordance with the processing target). Therefore, for example, in the character recognition shown in Patent Document 1, when general word dictionary information is used, the recognition accuracy deteriorates when the image information includes character string images such as technical terms and special abbreviations. There was a problem of doing. Furthermore, when using dictionary information with a large amount of information with an expanded correspondence range, as described above, there is a problem that the response deteriorates due to an increase in processing load or the recognition accuracy deteriorates.
Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to use even if a character string (word) image in a specific field is included in the image information to be processed. String recognition device and its program capable of improving the accuracy of character string recognition by using dictionary information used for character string recognition corresponding to the field without deteriorating the user's operability, and its character string recognition To provide an image reading apparatus including the apparatus, a dictionary information transmitting apparatus that transmits dictionary information to the character string recognition apparatus, and a program thereof.

To achieve the above object, the present invention provides a handler information acquisition means for acquiring handler information relating to a handler of the image information in a character string recognition device that recognizes character string information from image information including a character string image. Specific dictionary information acquisition means for acquiring specific dictionary information related to the handler information acquired by the handler information acquisition means from an external device or storage means for storing dictionary information in association with the handler information; Character string recognition output means comprising: character string recognition output means for recognizing and outputting character string information from the image information using the specific dictionary information.
In general, the field of image information to be processed is the person who handles the image information (the user who is trying to perform character string recognition processing, the other party to whom the image information is provided, the creator of the image information, etc.) Is closely related. Therefore, with the above configuration, character string recognition is performed using specific dictionary information related to the handler of the image information to be processed. Therefore, the dictionary information used for character string recognition should be appropriate for that field. The recognition accuracy of the character string can be improved by selecting. Here, the handler information acquisition means inputs or selects information about the handler of the image information (such as the user himself / herself) by, for example, user operation or automatic input from a wireless tag carried by the user. If it is a means, the user only needs to recognize the image information handler (the user himself / herself) and input the information, or there is no need to be aware of it, so the user's operability deteriorates. There is nothing.

On the other hand, the character string recognizing device having the above-described configuration acquires the specific dictionary information from an external device or a storage means in which dictionary information is stored in advance, and includes means for organizing the specific dictionary information. Is also possible.
That is, in a character string recognition device for recognizing character string information from image information including a character string image, handler information acquisition means for acquiring handler information regarding the handler of the image information, a plurality of word data, and the handler Information is stored in association with past usage frequency information of the word data by the handler, and is acquired by the handler information acquisition unit based on the stored information of the word usage frequency storage unit. First specific dictionary information organizing means for organizing specific dictionary information including word data frequently used by the operator in the past corresponding to the handled operator information, and the image information using the specific dictionary information. And a character string recognition output means for recognizing and outputting character string information.
Thereby, as the specific dictionary information related to the handler, dictionary information including word data frequently used in the past by the handler of the image information is automatically generated, so that it takes time to create dictionary information. Therefore, the recognition accuracy of the character string can be improved.
In this case, the handler information is grouped in advance, and the first specific dictionary information organizing unit includes the handler information belonging to the same group as the handler information acquired by the handler information acquiring unit. It is possible to include the word data frequently used in the past by the corresponding handler in the specific dictionary information.
In general, the handlers having common attributes such as departments and research themes often use a common word (character string). For this reason, the handler information is grouped in advance according to the department or research theme, etc., and a plurality of the handlers (corresponding to the handler information) belonging to the same group as the designated (acquired) handler information. The specific dictionary information related to the specified handler information can also be organized by collecting word data frequently used by the handler). As a result, for example, even when a new face or the like with little past use of word data is designated as the handler, it is possible to organize the appropriate specific dictionary information (rich in contents).
On the other hand, the word data is grouped in advance, and the first specific dictionary information organizing unit uses past information by the operator corresponding to the operator information acquired by the operator information acquiring unit. It is also possible to include the word data belonging to the same group as the word data with high frequency in the specific dictionary information.
In general, it is possible to group (classify) frequently used word data for each common attribute such as a business field or a technical field. For this reason, each word data is grouped (classified) in advance for each common attribute such as a business field or a technical field, and word data belonging to the same group as the frequently used word data of the specified handler is stored. If collected and included in the specific dictionary information, the specific dictionary information related to the specified handler information can be organized. Even with such a configuration, even if the operator or the like who has little use of past word data is specified, the appropriate specific dictionary information can be organized.

Further, the present invention may be understood as an image reading device provided with each of the character string recognition devices.
That is, an image reading unit that reads image information from a document on which a character string image is formed, and any one of the character string recognition devices that recognize character string information from the image information read by the image reading unit.

In an image reading device such as a network scanner, there is a means for inputting user identification information before use in order to reserve the use of the device or specify the transmission destination (user's own personal computer, etc.) of the read image information. There is something to prepare. If this is also used as the handler information acquisition means, it is not necessary to separately input the handler information in order to acquire or organize the specific dictionary information.
The user identification information input means is generally used to input a user ID, a password, etc. using an operation key, etc., but it reads an identification code such as a barcode recorded on a name tag, etc., or is incorporated in a name tag. A device that reads an identification code from a wireless tag or the like using a wireless signal is also conceivable.
The other one includes transmission destination information input means for inputting transmission destination information to the outside of the image information, and the transmission destination information input means is also used as the handler information acquisition means. Is the handler information.
Some image reading apparatuses such as a network scanner and a facsimile apparatus include means for inputting transmission destination information (e-mail address, telephone number, etc. of the other party) in order to externally transmit the read image. If this is also used as the handler information acquisition means, it is not necessary to separately input the handler information in order to acquire or organize the specific dictionary information.
Further, it is conceivable to include image information transmission means for transmitting the image information and the character string information output by the character string recognition output means together.
As a result, at the recipient of the image information, the image information having a large data size is not opened (displayed on the display means) by a dedicated program, and the character string information having a small data size is displayed and viewed. The contents of information can be grasped. For example, it is conceivable that the character string information is text information of the body of an e-mail, and the image information is sent as an attached data (attached file).

The present invention can also be understood as a dictionary information transmission device that transmits dictionary information to the character string recognition device.
That is, dictionary information transmission that is communicably connected to a character string recognition device that recognizes character string information from image information including a character string image, and transmits dictionary information used to recognize character string information to the character string recognition device. A device for receiving information about a handler of the image information from the character string recognition device, a plurality of word data, the handler information, and past data of the word data by the handler. Word usage frequency storage means stored in association with usage frequency information, and the handling corresponding to the handler information received by the handler information reception means based on the storage information of the word usage frequency storage means Second specific dictionary information organizing means for organizing specific dictionary information including word data frequently used by the user in the past, and the specific dictionary information before the sender of the handler information. A specific dictionary information transmitting means for transmitting the character string recognition unit, is constituted as dictionary information transmitting apparatus characterized by comprising comprises a.
As a result, the dictionary information transmitting device can be shared with a plurality of the character string recognizing devices (or image reading devices having the same), and dictionary information can be managed collectively.
Also in this case, as in the character string recognition device, the handler information is grouped in advance, and the second specific dictionary information organizing unit and the handler information received by the handler information receiving unit It is considered that the specific dictionary information includes the word data frequently used in the past by the handler corresponding to the handler information belonging to the same group.
On the other hand, the word data is grouped in advance, and the second specific dictionary information organizing means is used by the handler in the past corresponding to the handler information received by the handler information receiving means. It is also possible to include the word data belonging to the same group as the word data with high frequency in the specific dictionary information.
As a result, for example, even when a new face or the like with little past use of word data is designated as the handler, it is possible to organize the appropriate specific dictionary information (rich in contents).

Further, the present invention may be understood as a character string recognition program for causing a computer to execute processing executed by the character string recognition device.
That is, in a character string recognition program for causing a computer to execute processing for recognizing character string information from image information including a character string image, a handler information acquisition process for acquiring handler information regarding a handler of the image information; Specific dictionary information acquisition processing for acquiring specific dictionary information related to the handler information acquired by the handler information acquisition processing from an external device or storage means for storing dictionary information in association with the handler information; A character string recognition program for causing a computer to execute each process of character string recognition output processing for recognizing and outputting character string information from the image information using specific dictionary information.

A first specific dictionary information organizing process for organizing specific dictionary information including word data frequently used by the operator in the past corresponding to the handler information, and the image information using the specific dictionary information. A character string recognition output program that recognizes and outputs character string information and a character string recognition program that causes a computer to execute each process are also possible. .
Further, a computer-readable recording medium characterized by recording these character string recognition programs is also conceivable.

Similarly, the present invention may be understood as a dictionary information transmission program for causing a computer to execute processing executed by the dictionary information transmission apparatus.
That is, a dictionary used for recognizing character string information for the character string recognition device to a computer that is communicably connected to one or more character string recognition devices that recognize character string information from image information including character string images. A dictionary information transmission program for executing a process of transmitting information, a handler information reception process for receiving a plurality of word data and handler information relating to the handler of the image information from the character string recognition device; The handler information received by the handler information receiving means based on the storage information of the word usage frequency storage means for associating and storing the handler information and past usage frequency information of the word data by the handler. A second specific dictionary information organizing process for organizing specific dictionary information including word data frequently used in the past by the operator corresponding to the specific dictionary, and the specific dictionary A dictionary information transmitting program for executing a specific dictionary information transmission process of transmitting broadcast to the character string recognition apparatus of the transmission source of the handling person information, the processing of the computer.
Further, a computer-readable recording medium in which the dictionary information transmission program is recorded can be considered.

According to the present invention, handler information related to a handler of image information including a character string image is acquired, specific dictionary information related thereto is acquired or organized, and the specific dictionary information is used to obtain the information from the image information. Since character string information is recognized and output, the dictionary information used for character string recognition can be selected appropriately according to the handler (field) of the image information to improve the character string recognition accuracy. In addition, the user only needs to recognize the information related to the image information handler (the user himself / herself) and input the information, or there is no need to be aware of it, so the relationship between the image information and the dictionary information is not necessary. There is no need to be aware of it, and it does not cause any deterioration in the operability of users.
In addition, a plurality of pieces of word data, the handler information, and past usage frequency information of the word data by the handler are associated with the stored information stored in the storage means and correspond to the acquired handler information. By organizing specific dictionary information including word data frequently used by the operator in the past, as the specific dictionary information related to the operator, Since dictionary information including high word data is automatically generated, it is possible to improve character string recognition accuracy without the need for creating dictionary information.
In this case, the handler information is grouped in advance, and the word data frequently used in the past by the handler corresponding to the handler information belonging to the same group as the acquired handler information is identified. What is included in the dictionary information, or the word data is grouped in advance and belongs to the same group as the word data frequently used by the handler in the past corresponding to the acquired handler information As long as data is included in the specific dictionary information, the specific dictionary information that is appropriate (enriched in content) is appropriate even when the operator or the like who has little use of past word data is specified. Can be knitted.

The document database management unit 53 stores the acquired document file or the like in the storage unit 42 as the document database 425 in association with the user ID.
Further, when the acquired data is a document file, the document data receiving unit 55 outputs the document file to the word extracting unit 52 together with the user ID.

The technical term extraction unit 52 extracts technical terms from the document file supplied by the document data receiving unit 55 using the general word dictionary 423 and the technical term dictionary 424 stored in the storage unit 42.
Specific examples of the dictionary structure of the general word dictionary 423 and the technical word dictionary 424 are shown in FIGS. 4A and 4B, respectively.
As shown in FIGS. 4A and 4B, in the general word dictionary 423 and the technical word dictionary 424, a headword, its part of speech, and the like are stored for each key for identifying each word. .
In the general word dictionary 423, for example, as shown in FIG. 4A, words used daily such as “further”, “disc”, “home appliance”, “kanji”, “expression”, and the like are stored. . These words are words that are not so difficult to understand if there is knowledge necessary for social life, and are a collection of words that are not technical words. Also included are conjunctions necessary for composing sentences. The general word dictionary 423 can be updated by the dictionary maintenance unit 57 and is transmitted from the dictionary server Z to the scanner Y each time it is updated.
On the other hand, in the technical term dictionary 424, for example, as shown in FIG. 4B, “EUC”, “SED / sed”, “disk array”, “unicode”, “information appliance”, “regular expression”, Technical terms such as “third level” are stored. These technical terms are technical terms related to technology such as computers and semiconductors, technical terms related to art such as painting and music, and words required as specialized knowledge that is rarely used on a daily basis. is there.
The technical term extraction unit 52 performs the morphological analysis using the general word dictionary 423 and the technical term dictionary 424, and the technical terms stored in the technical term dictionary 424 from the document file, and the general term dictionary 424 Unknown words that are not stored in either the word dictionary 423 or the technical term dictionary 424 are extracted.
In the present embodiment, when the unknown word is extracted, the unknown word is stored in the technical term dictionary 424. That is, the unknown word is automatically regarded as the technical term. This reduces the work burden of registering a newly born word as the technical term.
The technical term extraction unit 52 associates the extracted technical term (including the unknown word) with the user ID provided from the document data receiving unit 55 and temporarily stores it in the storage unit 42 (not shown). ).
Note that the document file supplied to the technical term extraction unit 52 is not limited to the one via the document data receiving unit 55, and includes a document file input by directly operating the dictionary server Y. It is.

The usage frequency totaling unit 54 extracts the technical terms for each user ID and each technical term while referring to the correspondence between the technical terms temporarily stored in the storage unit 42 and the user ID. Frequency (that is, the past use frequency of the technical term by the user (creator or the like: an example of a handler) of the document file).
In addition, the usage frequency totaling unit 54 associates each technical term (a plurality of word data), the user ID (an example of the handler information), and information on the usage frequency, and forms the user-specific word database 422. It memorize | stores in the said memory | storage part 42 (an example of the said word usage frequency memory | storage means).
A specific example of the configuration of the user-specific word database 422 constructed in the storage unit 42 by the use frequency totaling unit 52 is shown in FIG. In the present embodiment, the user-specific word database 422 includes two database parts (FIGS. 5A and 5B).
As shown in FIG. 5 (a), one key of the database section constituting the user-specific word database 422 is given by a technical term or an alternative (technical term identification code or the like). For each technical term, for each user ID such as “Tanaka”, “Takahashi”, “Nakamura” (for convenience of explanation, a name is used but usually a code is used), the collected usage frequency (frequency) ) Is stored. In the example shown in FIG. 5A, the technical term “mirror disk” indicates that it has been used 180 times by “Tanaka”, 18 times by “Takahashi”, and 8 times by “Nakamura”.

On the other hand, each technical term registered (stored) in the technical term dictionary 424 is grouped in advance for each specialized field in consideration of the division unit of the organization, the classification of the research theme, and the like. It is the specialized field word database 42 that associates the specialized field with the specialized word.
FIG. 6 shows a specific example of the structure of the specialized field word database 42.
As shown in FIG. 6, the technical terms such as “RAID”, “disk array”, and “mirror disk” are grouped by being associated with a specialized field “HDD distributed multiplexing” (a pointer is set). Has been. This specialized field-specific word database 42 is set and inputted by the user when the database maintenance unit 56 executes a process of inputting or updating data through the user interface 41.
The technical word extraction unit 52 generates another database unit (FIG. 5B) that constitutes the user-specific word database 422 using the technical field-specific word database 42. Specifically, as shown in FIG. 5 (b), for each specialized field, for each user ID, the total usage frequency is a sum of the usage frequencies calculated for the technical terms belonging to the specialized field. The percentage is remembered.
That is, the database unit shown in FIG. 5B includes a plurality of technical terms (an example of word data), the user ID (an example of the handler information), and a user (a handler) corresponding to the user ID. It is a database (an example of the word usage frequency storage means) in which past usage frequency information (the ratio) of the technical terms (word data) is stored in association with each other.
In the example shown in FIG. 5B, among the technical terms used in the past by “Tanaka”, the usage frequency ratio of the technical terms belonging to the specialized field “HDD distributed multiplexing” is “0.392”. Represents the highest. Similarly, “Takahashi” has the highest usage rate of the technical term belonging to the specialized field “character code standardization” at “0.209”.
As will be described later, the dictionary server Z designates the user ID from the scanner Y and receives a request for a user dictionary (specific dictionary information) related to the user ID (a dictionary information request command described later). When received), the user-specific dictionary search unit 51 searches the specialized field having the highest use frequency ratio for the designated user ID, and further includes all the technical terms belonging to the specialized field (collected). D) Organize dictionary information and send it to the scanner Y via the communication unit.

Next, the scanner Y on which the character string recognition device X according to the embodiment of the present invention is mounted will be described.

The scanner Y includes a light source that irradiates light on a document, an optical system that deflects the reflected light, a CCD that receives the reflected light, and the like, and an image reading unit 21 that reads image information from the document (an example of the image reading unit). ), An image processing unit 22 that performs image processing such as shading correction on the read image information, a storage unit 23 that temporarily stores the read image data and stores various programs and other data, and a LAN. A network interface (I / F) 24 for performing communication control, a user interface 25 including operation keys operated by a user of the scanner Y to input various information, a liquid crystal display unit for displaying information, and the like Use a wireless communication means or IC card reader from a contactless tag or IC card carried by the user of the scanner Y. Reading the user ID is a user identification information (to get) the user ID input unit 26, and a control unit 30 that executes various control processes of the scanner Y.

The control unit 30 includes a character string recognition unit 31, a dictionary information storage unit 32, a user dictionary acquisition unit 33, an address selection unit 34, a format conversion unit 35, and a mail transmission unit 36. Here, the constituent elements of the character string recognition unit 31, the user dictionary acquisition unit 33, the address selection unit 34, the format conversion unit 35, and the mail transmission unit 36 are previously set by the CPU (not shown) constituting the control unit 30 in advance. This is implemented by executing a program module corresponding to each of the components stored in the storage unit 23.
The character string recognition unit 31 recognizes and outputs character string information from image information read by the image reading unit 21 (image reading unit) (image information after image processing by the image processing unit 22). is there.
The dictionary information storage unit 32 is a storage unit that stores dictionary information used by the character string recognition unit 31.
The user dictionary acquisition unit 33 obtains user dictionary information, which is specific dictionary information related to handler information (described later) regarding the handler of image information, from the dictionary server Z (external device) via the network interface 24. To get.
The address selection unit 34 selects the user interface 25 or the user ID input unit from among transmission destination addresses of image information stored in advance in the storage unit 23 (transmission destination information with each of the terminals 7 as a transmission destination). On the basis of the information input (acquired) by H.26, a transmission destination address (e-mail address) corresponding to the information is selected.
The format conversion unit 35 converts the image information read by the image reading unit 21 into a data format (TIFF format, JPG format, etc.) transmitted as an attached file of an e-mail, and the character string recognition unit 31 The character string information that is recognized and output is converted to the text information of the e-mail to which the image information is attached.
The e-mail transmission unit 36 uses the e-mail data converted by the format conversion unit 35, that is, the electronic data using the character string information recognized by the character string recognition unit 31 as the text and the corresponding image information as an attached file. Are transmitted via the network interface 24 with the transmission destination address selected by the address selection unit 34 as a destination. The transmitted e-mail data is transferred by the mail server 8 to the mail server 8 (self or another mail server 8) corresponding to the designated transmission destination address, and stored in the storage means.

In addition, the user ID input unit 26 uses a user ID for reservation of use of the scanner Y or for specifying a transmission destination when the read image information is transmitted to the user's own terminal 7 (external). (User identification information) is input (acquired) (an example of the user identification information input means).
In addition, when the user interface 25 transmits the image information read by the image reading unit 21 to the terminal 7 (external) of another person other than the user, the user interface 25 uses a destination address ( Used to select and input (destination information) (an example of the destination information input means).
As will be described later, the user ID input unit 26 and the user interface 25 are also used as means for acquiring handler information related to the handler of the read image information (corresponding to the handler information acquisition means). The user ID (an example of the user identification information) or the transmission destination address (an example of the transmission destination information) is used as the handler information.
Here, the character string recognition unit 31, the dictionary information storage unit 32, the user dictionary acquisition unit 33, the address selection unit, the user interface 25, and the user ID input unit 26 according to an embodiment of the present invention. The character string recognition device X is configured.

Next, the procedure of the push scan processing of the scanner Y will be described using the flowchart shown in FIG. The push scan process is a process for operating the scanner Y to read image information from a document and transmitting the image information to a specified destination. The processing shown in FIG. 7 is implemented when the control unit 30 executes a control program. Hereinafter, S1, S2,... Represent identification numbers of processing procedures (steps).
First, the control unit 30 inputs the user ID of the user who intends to operate the scanner Y and executes user authentication processing based on the user ID (S1).
As described above, the user ID is input via the user ID input unit 26 from the contactless tag or IC card incorporated in a name tag carried by the user via wireless communication or a dedicated interface. Enter. Of course, a configuration in which the user ID is input by the user interface 25 is also conceivable. Here, the user ID (not shown) registered (stored) in advance in the storage unit 23 is collated with the input user ID, and if they match, it is determined that user authentication has been established. To step S2. On the other hand, if the collated user IDs do not match, it is determined that user authentication has not been established, and the fact is displayed on the user interface 25, and then the process returns to S1 and is repeated (not shown).
Next, when the user authentication is established, the control unit 30 executes a function selection input process (operation selection) to be executed from the selection menu display or the like on the user interface 25 (S2). Although not shown, when the user authentication is established, the control unit 30 is in a state where the right to use the scanner Y is reserved by the user, that is, the scanner Y is connected to the other one via the network. The operation is shifted to a state in which operation from the terminal 7 or the like is prohibited.
If it is determined that a function other than the scanner function (for example, a user ID registration function) is selected, a process corresponding to the selected function is executed (S4), and the process is terminated.
On the other hand, if it is determined that the scanner function has been selected, the control unit 30 uses the address selection unit 34 to input destination information (an example of destination information to the outside) of image information read from the document. Execute (S10).
In this embodiment, image information is transmitted as an attached file of an e-mail, and this transmission destination information is an e-mail address of a transmission partner.
In the destination information input process (S10), first, a selection input of whether to select from already set (registered) destination information or to input new destination information through the user interface 25 and which Is determined (S11). Here, when a function to select from the already set destination information is selected, the set destination information is displayed on the user interface 25 as a menu, and a destination is selected and input from the menu (S12). ). On the other hand, if it is selected to input new destination information, a destination manual input process for inputting new destination information (e-mail address) through the user interface 25 is executed (S13).
At that time, the control unit 30 checks whether or not a scan start operation for starting image reading (scanning) from the document is performed through the user interface 25 (S14), and until the scan start operation is performed, The processing in step S10 is repeated assuming that the input operation of the transmission destination information has not been completed.

Here, both the user of the scanner Y and the transmission partner of the image information are examples of the handler of the image information, and the processing in step S3 or step 10 relates to the handler of the image information read by the image reading unit 21. It is an example of a means to acquire handler information.
In the present embodiment, the following two types of processing are possible depending on the function selection (S2 or S17 described later) of the user (operator).
One of them is that the user ID input unit 26 (an example of the user identification information input means) that inputs the user ID, which is identification information of the user (operator) of the scanner Y, acquires the handler information. It is also used as a means (S1), and the identification information of the user is used as the handler information.
The other one is that the address selection unit 34 for inputting (including selection) the transmission destination information (e-mail address) to the outside of the image information (the terminal 7 or the like) includes the transmission destination information acquisition unit. It is also used and the destination information is used as the handler information.
In an image reading apparatus such as a network scanner, user ID input means and transmission destination information input means are usually provided. If these are also used as the handler information acquisition means, the user dictionary (specific dictionary information) ), It is not necessary to separately input the handler information.

On the other hand, if it is determined that the scan start operation has been performed, the control unit 30 causes the image reading unit 21 and the image processing unit 22 to read image information from the document (S15), and further The format conversion unit 35 is caused to execute conversion processing of the read image information (image data) (conversion to a data format suitable for an attached file of an e-mail) (S16).
Further, the control unit 30 executes the processes of steps S17, S18, and S19 shown below in parallel with the processes of steps S15 and S16.
First, in step S17, the user ID or the transmission destination information (the handler) input (acquired) by the user dictionary acquisition unit 33 in step S3 or step S10 (an example of processing of the handler information acquisition means). A process of acquiring (obtaining) the user dictionary, which is specific dictionary information related to (an example of information), from the dictionary server Z (external device) is executed (S17, an example of a process of the specific dictionary information acquiring unit).
Here, the user dictionary (user identification information) input by the user ID input unit 26 (S1) by the user dictionary acquisition unit 33 or the transmission destination selected or manually input by the address selection unit 34 A dictionary information request command including information (e-mail address) is transmitted to the dictionary server Z via the network interface 24, and the user dictionary related to the user ID (the operator of the scanner Y) or the destination information (Specific dictionary information) is received (obtained) and temporarily stored in the dictionary information storage unit 32. Which of the user ID and the transmission destination information is used as the handler information, that is, the user dictionary related to the operator itself is requested, or the user dictionary related to the user of the transmission destination of the image information is The request is made to be selected by the operator at the time of selecting the function at step S2 or at step S17.

On the other hand, in the dictionary server Z, the communication unit 43 (an example of the handler information receiving means) causes the user ID (an example of the handler information) from the scanner Y (that is, the character string recognition device X). When the dictionary information request command is specified, the user-specific dictionary search unit 51 (FIG. 2) searches the database unit (FIG. 5B) that constitutes the user-specific word database 422, and is specified. For the user ID, the specialized field having the highest use frequency ratio is searched, and dictionary information including (collected) all the specialized terms belonging to the specialized field is organized. Send to Scanner Y.
Here, the user-specific dictionary search unit 51 uses the communication unit 43 (an example of the handler information receiving unit) based on the storage information of the user-specific word database 422 (an example of the word usage frequency storage unit). Organizing the user dictionary information (specific dictionary information) including word data frequently used in the past by a user (handler) corresponding to the user ID (an example of the handler information) received by It is an example of the specific dictionary information organization means.
Furthermore, the communication unit 43 transmits the user dictionary (specific dictionary information) to the character string recognition device X (scanner Y) that is the transmission source of the user ID (handler information). It is an example.

When the dictionary server Z receives the dictionary information request command in which the destination information (e-mail address of the destination, an example of the handler information) is specified from the scanner Y, first, the destination information The user ID corresponding to is acquired, and the same processing as when the user ID is designated is executed for the user ID.
The acquisition of the user ID is performed by, for example, registering (storing) a correspondence table (master database) between the transmission destination information (email address) and the user ID in advance in the dictionary server Y connected to the LAN of the management branch. It is conceivable that the dictionary server Y that has received the dictionary information request command inquires and obtains the corresponding user ID from the dictionary server Y of the management department by designating the destination information. . Of course, each of the dictionary servers Y may hold the correspondence table that is always updated to the latest state. In addition, the scanner Y itself inquires the user ID to the dictionary server Y of the management department, or the scanner Y stores the correspondence table in the scanner Y, so that the scanner Y obtains the user ID corresponding to the destination information. It is also conceivable to acquire and specify the dictionary information request command.
In the present embodiment, as described above, the technical terms (word data) are grouped in advance by the specialized field by the specialized field database 421 (FIG. 6), and the user-specific dictionary search unit 51 ( The second specific dictionary information organizing means) is the past by the user (handler) corresponding to the user ID or the destination information (handler information) received by the communication unit 43 (handler information receiving means). All the technical terms belonging to the same group as the technical term having the highest usage frequency (for example, the highest usage frequency ratio) are included in the user dictionary (specific dictionary information).
As a result, for example, even when a new face or the like who has little use of the technical terms in the past is designated as a user, the appropriate user dictionary can be organized (the contents are enriched).

In addition to the above, the user ID (handler information) is grouped and stored in advance, and the user-specific dictionary search unit 51 (second specific dictionary information organizing means) is connected to the communication unit 43 (handler information). The technical terms (word data) frequently used in the past by the user (handler) corresponding to all the user IDs belonging to the same group as the user ID (handler information) received by the information receiving means) What is included in a user dictionary (specific dictionary information) can also be considered.
As a means for grouping the user IDs, for example, the user IDs are grouped by associating them with common attributes such as business fields and technical fields in the storage unit 42 of the dictionary server Z of the management department. It is conceivable to store the user information database 426 and refer to it via the LAN. The user information database 426 is input by the user through the database maintenance unit 56.
Even with such a configuration, it is possible to organize the appropriate user dictionary (enriched contents) even when a user with a low use record of the technical term in the past is designated.

Next, in step S18, the control unit 30 uses the character string recognition unit 31 to read image information read by the image reading unit 21 (image reading unit) (image information output from the image processing unit 22). A process of extracting character string information (character code string, that is, word) from is executed (S18).
Here, the character string recognition unit 31 first cuts out a portion assumed to be a character from the image information. Further, character information (character code) is extracted from the cut-out portion by collating with the font data (character data of each character) stored in advance in the storage unit 23, and the character string information obtained by connecting them. By comparing the character code string (that is, the word candidate) with the general dictionary stored in advance in the dictionary information storage unit 32 (downloaded every time the dictionary server Z is updated), Character string information is extracted by performing first-stage character string recognition.
Further, in step 19, the control unit 30 obtains the user dictionary for the character string information extracted from the character string recognition unit 31 in step S17 (as a result of the first stage character string recognition). Using the user dictionary acquired by the unit 33 (S17), a character string information correction process is executed as a second-stage character string recognition process (S19). The character string information recognized (extracted) in steps S18 and S19 is output to the format converter 35.
In this step S19, the character string information (word) portion that could not be extracted by the collation with the general dictionary in step S18 and the character string information of the portion before and after that portion are collated with the user dictionary. , Correct character string information.
Thus, since the character string recognition is performed using the user dictionary related to the handler of the image information to be processed, accurate character string recognition can be performed even for the technical term that cannot be recognized by the general dictionary. This can improve the accuracy of character string recognition. In addition, the user only needs to recognize information related to the image information handler (the user himself / herself or the transmission destination) and input the information, or is conscious of what is automatically acquired by the wireless tag or the like. Since there is no need, the user's operability is not deteriorated.
Here, the processing of steps S18 and S19 by the character string recognizing unit 31 recognizes and outputs character string information from image information using the user dictionary (an example of the specific dictionary information). It is an example of the process of a means.

Next, when the processing of steps S15 to S19 is completed, the control unit 30 generates e-mail data by the format conversion unit 35.
Here, the e-mail data in which the image information converted into the predetermined format in step S16 is an attached file of the e-mail, and the character string information extracted (recognized) from the image information in step S19 is the text text information of the e-mail. Is generated. Further, as the transmission destination address, the transmission destination information selected or input in step S10 is set.
Finally, the control unit 30 causes the mail transmission unit 36 to transmit the e-mail data generated in step S20 via the network interface 24 (S21), and then ends the process.
Thus, the transmitted e-mail data is transferred by the mail server 8 to the mail server 8 (self or another mail server 8) corresponding to the specified destination address based on the SMTP protocol or the like, and its storage means. Accumulated in. The accumulated electronic mail data is acquired by the terminal 7 that has accessed the mail server 8.
Thus, the e-mail combining the image information and the character string information output by the character string recognition unit 31 (character string recognition output unit) by the mail transmission unit 36 (an example of the image information transmission unit). Data is transmitted to the terminal 7 (external). As a result, at the recipient of the image information, the contents of the image information can be obtained simply by displaying and displaying the character string information having a small data size without opening (displaying on the display means) the image information having a large data size by a dedicated program. Can be easily grasped.

In the embodiment described above, the user-specific dictionary search that organizes the user dictionary (specific dictionary information) in the dictionary server Z that is an external device of the scanner Y on which the character string information recognition device X is mounted. The example which provided the part 51 was shown.
On the other hand, the user-specific dictionary search unit 51 (an example of the first specific dictionary organizing unit) is provided in the character string information recognition device X, whereby the user ID input unit 26 inputs (acquires) the A configuration for organizing the user dictionary (specific dictionary information) related to the user ID (handler information) is also conceivable. Further, a configuration in which the character string information recognition device X (that is, the scanner Y) is provided with the user-specific word database 422 (an example of the word use frequency storage means) is also conceivable.
Further, it is also conceivable that each program (program module) executed by the control unit 50 for realizing the function of the character string information recognition apparatus X is configured as a character string recognition program that causes a computer such as a personal computer to execute the program. . In this case, the image information is processed by the processing executed by the character string recognition unit 31 (character string recognition output means), the processing executed by the user dictionary acquisition unit (specific dictionary information acquisition means) 33, and input means such as a keyboard and a mouse. What is necessary is just to comprise the program for making a computer perform each process (process of a handler information acquisition means) which inputs (acquires) the person (user of a computer, etc.). Of course, it is also possible to use a computer-readable recording medium such as a CD-ROM or DVD-ROM on which such a program is recorded.
Similarly, a computer-readable recording medium such as a CD-ROM or a DVD-ROM on which a program executed by the dictionary server Z is recorded is also conceivable.
