Description

  The present invention relates to a mobile terminal, a management server, an e-mail transmission / reception system, and an e-mail transmission / reception method, and in particular, an e-mail connected from a mobile terminal to an Internet network via a wireless line or a wired communication line. The present invention is suitably applied to an information transmission / reception system that communicates by exchanging information by, for example.

  With the development of electronic devices such as computers and portable terminals, anyone can express beautiful characters without using pencils or other writing tools. However, many people are dissatisfied with such uniform fonts. This is because the character string of the same font decided by anyone can give the impression that it is psychologically cold and timid, and may affect communication. Against this background, many techniques have been invented to reproduce handwritten texture and warmth instead of fonts prepared in advance, such as image data such as FAX, techniques that extract handwritten movements, and original Various methods such as creating a simple font have been disclosed.

  As a technique for creating a handwritten character font, there is Japanese Patent Laid-Open No. 2003-58142 “Handwritten character font generation system, recording medium, and program” disclosed in Patent Document 1. In Patent Document 1, a user writes a text of about 100 characters selected in advance on a manuscript paper, and after handwritten characters are captured as an image by a scanner, the size and spacing of characters are compared with a standard font. Extracts feature parameters related to handwriting, such as tilt and tilt. Thereafter, for the text created by the user using the standard font, a font imitating the user's handwriting is created from the standard font using the feature parameters extracted previously.

Japanese Patent Application Laid-Open No. 2002-324027 shown in Patent Document 2 defines a method called an ink font in which coordinate information of each character font is recorded. Proposes a way to send information as email. The ink font is obtained by coding and storing the coordinate information (X coordinate, Y coordinate) of the trajectory when writing a character with an electronic pen, and at the time of reproduction, according to the coordinate information of the coded trajectory, By drawing a line segment, characters are formed as the locus of the line segment. For example, by having an ink font corresponding to each character code in the mail server, when the mail is sent, each character data of the mail is converted into motion information (coordinate information of the locus) by the mail server. By converting and transferring, even if the receiving terminal is not equipped with a special character font, by drawing the line segment according to the movement information of the line segment expressed as the coordinate data of the point sequence, Characters specific to the user can be expressed.

  However, Patent Document 1 relates to a technique for creating a character string of a handwritten style character font using the previously extracted feature parameters. Even so, there is a problem that a handwritten-style character string cannot be reproduced unless the character font created on the e-mail receiving terminal side is provided. Further, in Patent Document 2, since it is necessary to write each character once using an electronic pen in order to create motion information of a line segment that is an ink font, it takes time to create an ink font. Take it. In addition, since it is necessary to transmit the coordinate data of the point sequence to the receiving terminal side when sending an e-mail, there is a problem that the amount of transmission data is always large and is not suitable for communication with a portable terminal. ing.

  The present invention has been made in view of such a situation, and does not depend on the type of the target mobile terminal, and conforms to the specifications of each mobile terminal, with a minimum amount of transmission data, An object of the present invention is to provide means and a method for allowing handwriting characters peculiar to a sender to be displayed on a receiver's portable terminal.

  In the present invention, in order to solve such a problem, a user of a mobile terminal on the transmission side registers in advance a characteristic parameter extracted from the handwriting of his / her character and transmits it according to the specifications of the mobile terminal on the reception side. The data type related to the character data to be changed is changed to send the e-mail. That is, the receiving-side mobile terminal has already set a transmitting-side characteristic parameter (information indicating the characteristics of the sender's handwriting) that can generate an original font for the sender with respect to text data that the transmitting-side mobile terminal intends to transmit as an e-mail. If it is in the possessed state, the transmitting side portable terminal transmits only text data composed of standard fonts. On the other hand, the receiving-side portable terminal can convert the text data of the received e-mail into the original font unique to the sender, display it on the screen, and browse it using the transmitting-side characteristic parameter that is already held.

  When there is a possibility that the transmitting-side portable terminal has one or more transmitting-side feature parameters, a feature parameter ID (identifier) that can identify each of the one or more transmitting-side feature parameters is assigned. In such a case, when sending an e-mail from the sending side portable terminal, a feature parameter ID for specifying a sending side feature parameter used for converting the text data of the e-mail into an original handwritten font is set. By transmitting the text data together with the text data, the receiving side portable terminal can convert the text data of the received e-mail and display it on the screen using the transmitting side characteristic parameter specified by the characteristic parameter ID.

  In addition, when the receiving side mobile terminal does not have the transmitting side characteristic parameter of the transmitting side mobile terminal, the transmitting side mobile terminal transmits the text data composed of the standard font and the handwriting of the transmission source. And feature parameters. As a result, the receiving-side mobile terminal refers to the transmitted sending-side characteristic parameter, and creates a handwritten-style original font that is a modified standard font based on a specific rule. The text data can be displayed on the screen using handwritten fonts corresponding to the transmission side characteristic parameters.

  In addition, when the receiving mobile terminal does not have a function of creating an original font similar to the sender's handwriting from the transmitting side characteristic parameter, the transmitting mobile terminal uses the text image data of the e-mail from the document image. Is converted into image data and transmitted. In that case, by adding character data consisting of text information, it is possible to facilitate the retrieval of the e-mail in the receiving mobile terminal and the quoting at the time of reply / transfer from the receiving mobile terminal.

  In this way, the data type to be transmitted as an e-mail is changed depending on whether or not the receiving-side mobile terminal has a function of creating a handwritten-style original font similar to the sender's handwriting from the transmitting-side feature parameter By optimizing the data amount of the e-mail to be transmitted according to the specifications of the receiving mobile terminal, and the receiving mobile terminal, in any case, the text corresponding to the transmitting feature parameter, that is, the sender's It becomes possible to browse sentences similar to handwriting.

  Hereinafter, as an example of an embodiment of a mobile terminal, a management server, an e-mail transmission system, and an e-mail transmission method according to the present invention, an example of a method for utilizing an original font on a transmission side in a mobile terminal will be described in detail based on the drawings. . FIG. 1 is a block diagram showing an example of the configuration of an e-mail transmission / reception system that utilizes an original font on the transmission side in a portable terminal according to the present invention. The electronic mail transmission system configuration in FIG. 1 includes a transmission-side portable terminal 10, a reception-side portable terminal 11, and a feature parameter management server 12. In addition, although the case where a mobile telephone is used is shown as an example as the transmitting-side mobile terminal 10 and the receiving-side mobile terminal 11, it may of course be a PDA or a portable personal computer having communication means including radio. .

  In FIG. 1, the transmitting-side mobile terminal 10 extracts features relating to the handwriting of the transmitting-side user as feature parameters, creates a feature parameter file, and sends the feature parameter file to the feature parameter management server 12. Send with sender's name and email address for sender. The feature parameter management server 12 that has received the feature parameter file assigns a unique feature parameter ID (identifier) for identifying and specifying the feature parameter file, and associates the feature parameter file with the assigned feature parameter ID. Are registered in the feature parameter registration table with the file name assigned to the sender's e-mail address and the feature parameter file. In the example shown in FIG. 1, if the creator of the transmission source is, for example, “Tazaki” and the mail address is “tazaki @ .. co.jp”, “Tazaki font” is used as the feature parameter file name. In addition, “0” is assigned and registered as a feature parameter ID for uniquely specifying the “Tazaki font” feature parameter file.

Furthermore, the feature parameter management server 12 replies to the transmission source mobile terminal 10 that the feature parameter ID issued for identifying the “Tazaki font” feature parameter file is “0”.
When transmitting the e-mail to the receiving-side portable terminal 11, the transmitting-side portable terminal 10 transmits the “Tazaki font” feature parameter file itself as a sending-side feature parameter in addition to the text data of the body of the e-mail. Or whether the feature parameter ID returned from the feature parameter management server 12 is transmitted together with the text data of the e-mail, or the text data of the e-mail is converted into an image and transmitted in addition to the text data. Are edited according to the correspondence status with respect to the transmission-side characteristic parameter in the reception-side portable terminal 11 and transmitted to the reception-side portable terminal 11.

  In addition, when there is only one type of transmission-side characteristic parameter applied to the e-mail from the transmission-side mobile terminal 10, the reception-side mobile terminal 11 sends the sender name or the transmission-source mail of the received e-mail. Since the transmission side characteristic parameter can be identified by the address or the like, it is not always necessary to transmit the characteristic parameter ID together with the text data, and only the text data needs to be transmitted.

Next, FIG. 2 shows a block configuration diagram showing an example of a block configuration of a mobile terminal according to the present invention applied to the transmission-side mobile terminal 10 and the reception-side mobile terminal 11 shown in FIG.
In the system configuration diagram of FIG. 2, the mobile terminals 10 and 11 include at least a feature parameter extraction unit 1, a font generation unit 2, a document image creation unit 3, a control unit 4, a communication unit 5, a display unit 6, a built-in camera 7, The control unit 4 includes a data type selection unit 4a, a characteristic parameter correspondence status notification unit 4b, and an image capturing unit 4c.

  The feature parameter extraction unit 1 extracts feature parameters that enable generation of a font (original font) only for the user from handwriting regarding a plurality of specific characters handwritten by the user of the mobile terminal. Based on the feature parameter extracted by the feature parameter extraction unit 1, the font generation unit 2 deforms an arbitrary character set as a standard font in the mobile terminal, and extracts the character parameter from the character font. It is generated as an original font that closely resembles the handwriting of the specific character that is the basis of the action.

  In addition, as a technique for extracting feature parameters of a plurality of specific characters, a technique as disclosed in Patent Document 1 may be used. For example, the user handwrites a plurality of predetermined specific characters on a document sheet. A specific character handwritten on the original paper is photographed as an image by the built-in camera 7 built in the portable terminal, and the photographed image image is captured by the image capturing means 4c of the control unit 4 to identify the specific character in the image image. Extract characters. The feature parameter extraction unit 1 compares the specific character in the extracted image image with the character of the standard font set in the mobile terminal, thereby writing the handwriting such as the character size, spacing, and inclination of the specific character. Extract feature parameters.

  Further, each user of the mobile terminal may create his own font from arbitrary feature parameters in the font generation unit 2 in addition to the original font that closely resembles his handwriting. A plurality of characteristic parameters and a plurality of original fonts based thereon may be held. Further, the method of taking handwritten character information into the mobile terminal to extract the characteristic parameters is not limited to the built-in camera 7 built in the mobile terminal, and a touch panel, a handy scanner, or the like may be used.

  In addition, when a sentence such as an e-mail is created on the mobile terminal, each character of the created sentence is handled in the font generation unit 2 by using the feature parameter previously extracted by the feature parameter extraction unit 1 The character of the original font to be generated may be generated, or the feature parameter extraction unit 1 and the font generation unit 2 may be provided in a device different from the portable terminal, and the feature parameter extraction unit of the separate device The feature parameters extracted in step 1 and the handwritten-style original font generated by the font generation unit may be taken into the portable terminal.

  Further, as shown in the configuration diagram of FIG. 1, the feature parameter extracted in the transmission-side portable terminal 10 is transmitted from the transmission-side portable terminal 10 to the feature parameter management server 12 via the communication unit 5. Then, a registration request is made to the feature parameter management server 12. The feature parameter management server 12 that has received the registration request can add the file name to the transmitted feature parameter and register it in the feature parameter registration table, and can uniquely identify and specify the registered feature parameter file. A possible characteristic parameter ID is assigned, and the assigned characteristic parameter ID is returned to the transmitting-side portable terminal 10. The transmitting-side portable terminal 10 receives the returned feature parameter ID and stores it in the transmitting-side area of the storage unit 8 in association with the extracted feature parameter.

  The feature parameter ID assigned by the feature parameter management server 12 (hereinafter, may be simply abbreviated as “ID”) is unique for each feature parameter file registered in the feature parameter registration table. It is issued as an identification number, which makes it possible to identify a registered feature parameter file from a user of another portable terminal. Further, by associating the ID with each feature parameter file, even one transmission-side mobile terminal 10 can have a plurality of feature parameter files as described above. In addition to the original font used, it is possible to have a font characteristic for the user.

  The feature parameter management server 12 registers and manages the feature parameter requested for registration and the ID assigned to the feature parameter file in the feature parameter registration table. As shown in FIG. In addition to this, in order to strictly manage the ID and ID, in addition to this, the feature parameter registration table is registered and managed including the sender name indicating the registration requesting user and the mail address for the sender. I am doing so.

  After the registration of the feature parameter to the feature parameter management server 12 and the issuance of the ID are completed, the transmitting-side portable terminal 10 uses the data type selection unit 4a of the control unit 4 to receive the receiving-side portable terminal 11. When sending an e-mail to the e-mail, in addition to the text data of the e-mail body (character string data made up of standard fonts), depending on the response status of the sending-side feature parameter in the receiving-side mobile terminal 11, The characteristic parameter file itself is transmitted as a transmission-side characteristic parameter, or an ID for identifying the transmission-side characteristic parameter file is transmitted at the time of text data transmission, or the text data of the e-mail body is used by the document image creation unit 3 Hand-drawn image (document image) generated based on the sending side feature parameter An image), or sent to other text data, selects one of the data type.

  The transmission-side portable terminal 10 transmits an electronic mail created according to the data type selected by the data type selection unit 4 a to the reception-side portable terminal 11 via the communication unit 5. As described above, when the transmitting-side portable terminal 10 has only one type of transmitting-side feature parameter, the text of the e-mail body is not transmitted without transmitting an ID for specifying the transmitting-side feature parameter. Only data may be transmitted.

  When creating text data of the e-mail body on the transmitting-side mobile terminal 10, the user creates it while looking at the screen of the display unit 6, and further creates a text image composed of the standard font created as the e-mail body. It can be converted into a handwritten character string using the original font generated from the transmission side characteristic parameter in the unit 3 and displayed on the display unit 6 on the screen. Further, in the reception-side mobile terminal 11, not only the received e-mail text data and document image image but also the received e-mail body is generated from the transmission-side feature parameters by the font generation unit 2 and the document image generation unit 3. It is also possible to convert it into a handwritten character string using the original font on the transmission side and display it on the display unit 6 on the screen.

  Further, the feature parameter correspondence status notifying means 4b of the control unit 4 is necessary as the receiving-side mobile terminal 11, and when receiving the e-mail from the transmitting-side mobile terminal 10, the transmitting-side feature of the e-mail is received. It is determined whether the parameter has already been received and stored in the reception side area of the storage unit 8 or whether the transmission side characteristic parameter of the e-mail has not been received yet. Is a reply. Here, when not only the text data of the e-mail but also the ID specifying the transmission side characteristic parameter is received from the transmission side portable terminal 10, the transmission side characteristic parameter corresponding to the received ID is stored in the storage unit 8. It is determined whether it is held in the receiving side area.

  The configuration of the mobile terminal shown in FIG. 2 is shown as a transmission / reception mobile terminal capable of transmitting and receiving e-mails. However, in some cases, the mobile terminal 10 is configured as a transmission-side mobile terminal 10 that only transmits e-mails. The feature parameter correspondence status notifying means 4b or the like which is a means dedicated to reception may not necessarily be provided, or the characteristic parameter which is a means dedicated to transmission may be configured as the reception-side portable terminal 11 that receives an e-mail. The extraction unit 1, the document image creation unit 3, the built-in camera 7, the image capturing unit 4c, and the like may not necessarily be provided.

  Next, a processing procedure for selecting a data type related to electronic mail in the transmitting-side mobile terminal 10 will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart for explaining an example of a processing procedure for selecting the data type of the electronic mail to be transmitted in the transmission-side portable terminal 10 according to the present invention.

The procedure is shown.
In the flowchart of FIG. 3, a case is described in which an ID for specifying a transmission-side characteristic parameter is transmitted from the transmission-side portable terminal 10 when an e-mail is transmitted.

  In the flowchart of FIG. 3, first, the transmission-side portable terminal 10 reads an ID for specifying the transmission-side feature parameter in the transmission-side portable terminal 10 from the transmission-side area of the storage unit 8, and (Step S1). Next, the transmitting-side mobile terminal 10 determines whether or not the response status for the transmitting-side feature parameter specified by the transmitted ID is returned from the receiving-side mobile terminal 11 within a predetermined time period ( Step S2). If it is detected that the message has been returned (YES in step S2), based on the result of the corresponding situation in the receiving portable terminal 11 with respect to the transmitting feature parameter specified by the ID, the transmitting feature parameter is It is determined whether or not the terminal 11 has already received and the receiving-side portable terminal 11 holds the transmitting-side characteristic parameter in the receiving-side area of the storage unit 8 (step S3).

  The correspondence status with respect to the transmission-side feature parameter is the response to the transmission-side feature parameter specified by the ID when the reception-side portable terminal 11 receives the ID of the transmission-side feature parameter from the transmission-side portable terminal 10. Is information that is sent back to the transmitting-side portable terminal 10. The correspondence status with respect to the transmission side characteristic parameter also includes information indicating whether or not the transmission side characteristic parameter corresponding to the ID received by the reception side portable terminal 11 has already been received and held in the reception side area of the storage unit 8. include.

  As a result of determining the response status of the reception-side portable terminal 11 to the transmission-side feature parameter, the reception-side portable terminal 11 has received the transmission-side feature parameter corresponding to the ID, and the transmission-side feature parameter is received by the storage unit 8. If it is determined that the data is held in the side area (YES in step S3), since the transmission side characteristic parameter of the transmission side portable terminal 10 has already been transmitted first, the data type to be transmitted as an e-mail Thus, it is sufficient to send only text data composed of the standard font of the mail body (step S4).

  On the other hand, as a result of the determination of the response status of the reception-side portable terminal 11 to the transmission-side feature parameter, the reception-side portable terminal 11 is in a state of not receiving the transmission-side feature parameter corresponding to the ID, and stores the transmission-side feature parameter If it is determined that the data is not held in the reception side area of the unit 8 (NO in step S3), the transmission side feature stored in the transmission side area of the storage unit 8 as a data type to be transmitted as an e-mail It is assumed that the parameter is transmitted in addition to the text data composed of the standard font of the mail body (step S5).

  If the response status for the transmission-side feature parameter specified by the transmitted ID is not returned from the reception-side mobile terminal 11 within a predetermined time (NO in step S2), the transmission-side mobile terminal 10 Even if the transmission side characteristic parameter of the transmission side portable terminal 10 is transmitted, the reception side portable terminal 11 that cannot reproduce the handwritten character from the text data of the e-mail body from the transmission side portable terminal 10 Judge that there is. In this case, the transmitting-side portable terminal 10 converts the text data of the mail body into a document image image (image data) by the document image creation unit 3 shown in FIG. As a data type to be transmitted, the created document image is transmitted in addition to the text data composed of the standard font of the mail body (step S7).

  Next, when the reception-side mobile terminal 11 receives the feature parameter ID transmitted from the transmission-side mobile terminal 10, it determines the response status for the transmission-side feature parameter specified by the received ID, A processing procedure for returning to the transmitting-side portable terminal 10 will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart for explaining an example of a processing procedure for returning the response status to the feature parameter specified by the feature parameter ID received by the reception-side mobile terminal 11 according to the present invention. Note that the flowchart of FIG. 4 also shows a case in which an ID for identifying a transmission-side feature parameter is transmitted from the transmission-side portable terminal 10 corresponding to the flowchart of FIG.

  The characteristic parameter correspondence status reply processing procedure shown in the flowchart of FIG. 4 is executed by the characteristic parameter correspondence status notification means 4b of the control unit 4 shown in FIG. A feature indicating whether or not a transmission-side feature parameter corresponding to the ID has already been received and is held in the reception-side area of the storage unit 8 when the ID of the transmission-side feature parameter is received from The parameter correspondence status is returned to the transmitting-side portable terminal 10.

  In the flowchart of FIG. 4, first, when the reception-side mobile terminal 11 receives an ID related to the transmission-side feature parameter from the transmission-side mobile terminal 10, the transmission-side feature parameter specified by the ID has already been received and the storage unit 8 receives the ID. It is determined whether or not it is held in the side area (step S11). When the receiving-side portable terminal 11 is already in the state of holding the transmitting-side feature parameter specified by the ID in the receiving-side area of the storage unit 8 (YES in step S12), the transmitting-side feature parameter specified by the ID As a response status, the transmission side characteristic parameter is returned to the transmission side portable terminal 10 as having been received (step S13).

  On the other hand, if the receiving-side mobile terminal 11 has not received the transmitting-side characteristic parameter specified by the ID and has not yet held it in the receiving-side area of the storage unit 8 (NO in step S12), transmission is performed. As a correspondence situation of the side feature parameter, although a means for creating a handwritten-like character font based on the transmission side feature parameter is provided, it is assumed that the corresponding transmission side feature parameter has not been received. A reply is made (step S14).

  That is, if the transmission-side feature parameter corresponding to the feature parameter ID transmitted from the transmission-side portable terminal 10 has been received and is held in the reception-side area of the storage unit 8, As described with reference to FIG. 3 above, only text data (a character string made up of standard fonts) that is the mail body is transmitted from the terminal 10, so that the receiving-side mobile terminal 11 receives from the transmitting-side mobile terminal 10. The sender-side characteristic parameter specified by the ID is read from the receiving-side area of the storage unit 8, and the font generation unit 2 generates an original font that closely resembles the handwriting of the sender. Are converted into original font characters by the document image creation unit 3, and the received mail text is displayed on the display unit 8 using the converted font characters. Screen display.

  On the other hand, if the transmission-side characteristic parameter specified by the transmitted ID is not received and is not yet held in the reception-side area of the storage unit 8, the transmission-side mobile terminal 10 As described with reference to FIG. 3, in addition to the text data that is the mail body, the transmission side characteristic parameter is transmitted. Therefore, the reception side portable terminal 11 first receives the received characteristic parameter ID of the transmission side characteristic parameter. Are registered in the receiving side area of the storage unit 8 in association with each other. Further, the receiving-side portable terminal 11 generates an original font that closely resembles the sender's handwriting by the font generation unit 2 using the received transmitting-side feature parameter, and receives each character of the text data that becomes the received mail body. Is converted into original font characters for the sender by the document image creation unit 3 and the received mail text is displayed on the display unit 8 using the converted font characters.

  By performing the e-mail transmission / reception process as described above, it is possible to display on the screen a sentence that closely resembles the sender's handwriting, and to realize communication of e-mail with a warm sentence Can do.

  Note that the receiving-side portable terminal 11 does not include, for example, the font generation unit 2 or the document image creation unit 3, and even if it receives the transmission-side feature parameter, If the character cannot be reproduced, the reception-side portable terminal 11 notifies the transmission-side portable terminal 10 of the response status for the transmission-side feature parameter without activating the feature parameter response status notifying unit 4b as shown in FIG. No action is taken to send a reply.

  Therefore, as described above with reference to FIG. 3, when the transmitting-side mobile terminal 10 cannot receive the response status for the transmitting-side feature parameter from the receiving-side mobile terminal 11 within a predetermined time period, In the data type selection unit 4a of the transmission-side portable terminal 10, a data type is selected such that a document image image related to the text data is transmitted in addition to the text data of the mail body. Thus, the document image creation unit 3 of the transmission-side portable terminal 10 creates the text data of the mail body as a document image image using the original font of the handwriting that the user wants to use generated from the transmission-side feature parameters. In addition to the text data of the mail body, the data is transmitted to the mobile terminal 11 on the receiving side.

  The receiving-side mobile terminal 11 that has received the document image image in addition to the text data of the mail body displays the received document image image on the screen of the display unit 6. As a result, even if the receiving-side mobile terminal 11 that receives the e-mail is a terminal that cannot reproduce the original font based on the transmitting-side characteristic parameter, the document image image generated by the transmitting-side mobile terminal 10 is displayed on the screen. , It will be displayed on the screen as a sentence very similar to the handwriting of the sender. Furthermore, since the text data of the mail body is also received in addition to the document image image, it can be easily searched when the received mobile terminal 11 searches for the received mail, or It is also possible to transmit only text data without using a document image when returning to the transmitting-side portable terminal 10 or transferring to another portable terminal.

  In the case of FIGS. 3 and 4, when the transmission-side mobile terminal 10 determines whether to create a document image image of text data of the mail body, the response from the reception-side mobile terminal 11 to the transmission-side feature parameter. Although the determination is made based on whether or not the situation is returned within a predetermined time, the present invention is not limited to such a case. For example, when the reception-side mobile terminal 11 cannot reproduce the characters in the handwritten-style font using the transmission-side feature parameter, the transmission-side feature is used as the feature parameter correspondence status notifying unit 4b of the reception-side mobile terminal 11. The transmission side portable terminal 10 may be returned with a response status to the transmission side characteristic parameter indicating that the character of the handwritten font cannot be reproduced using the parameter. 10, it is also possible to operate so as to create a document image when receiving the corresponding situation indicating that characters in a handwritten font cannot be reproduced.

  As described above, the data type of the e-mail transmitted to the receiving mobile terminal 11 is changed in accordance with the response status of the receiving mobile terminal 11 to the transmitting side characteristic parameter. It is possible to send an e-mail with the minimum amount of data in accordance with the specifications, and to display on the display unit 6 a text in handwritten style original font that resembles the sender's handwriting on the receiving mobile terminal 11 It becomes.

Moreover, although an example of the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say. The same applies to applications.
For example, a terminal that transmits and receives e-mails is not limited to a portable terminal such as a mobile phone, a PDA, or a portable PC, and may be a desktop or notebook PC, or as data to be transmitted and received, There is no need to limit to only e-mail, and general document data may be transmitted and received.

  Further, in the embodiment shown in FIGS. 3 and 4, the feature parameters are managed by the feature parameter for identifying the response status of the reception-side portable terminal 11 with respect to the transmission-side feature parameter and identifying the transmission-side feature parameter. Although the example using ID (feature parameter ID) when registering in the server 12 has been shown, the present invention is not limited to this. As described above, when the transmission-side portable terminal 10 has a plurality of transmission-side feature parameters, each transmission-side portable terminal 10 for specifying which transmission-side feature parameter is used to generate a handwritten-style font. The ID may be a unique ID, or when the transmitting-side portable terminal 10 has only one type of transmitting-side feature parameter, the sender name or By using the e-mail address for the sender or the header information of the feature parameter file (font file), the reception-side portable terminal 11 stores the correspondence status with respect to the transmission-side feature parameter, the transmission-side feature parameter, and the original font. The installation status in the receiving side area of the unit 8 may be identified.

  In addition, when the reception-side portable terminal 11 does not hold the transmission-side feature parameter of the transmission-side portable terminal 10 in the reception-side area of the storage unit 8, the transmission-side feature parameter file is transmitted from the transmission-side portable terminal 10 in addition to the mail text. The receiving-side mobile terminal 11 may dynamically acquire the transmitting-side feature parameters registered by the transmitting-side mobile terminal 10 from the feature parameter management server 12 shown in FIG. I do not care.

  Further, as shown in the configuration diagram of FIG. 5, the mail server 13 that manages the transmission and reception of e-mails has the function of the feature parameter management server 12 described above with reference to FIG. The side portable terminal 10 may be provided with a feature parameter registration table for registering each transmission side characteristic parameter, or original font information for each transmission side portable terminal 10 may be registered. FIG. 5 is a configuration diagram showing an example different from FIG. 1 of the configuration of the e-mail transmission / reception system utilizing the original font on the transmission side in the portable terminal according to the present invention.

  In FIG. 5, the e-mail transmitted / received between the transmitting-side portable terminal 10 and the receiving-side portable terminal 11 is transmitted / received once via the mail server 13, and the transmitting-side portable terminal 10 As described above, each of the transmitting side characteristic parameters is registered in advance in the characteristic parameter registration table of the mail server 13. On the other hand, the reception-side mobile terminal 11 also registers in advance the correspondence status of each transmission-side feature parameter of the transmission-side mobile terminal 10 in the reception-side mobile terminal correspondence status registration table of the mail server 13.

  When the transmission-side portable terminal 10 transmits an e-mail to the reception-side portable terminal 11 to the mail server 13, the transmission-side portable terminal 10 receives the transmission-side characteristic parameter of the transmission-side portable terminal 10. As shown in FIG. 3, the data type of the e-mail is changed according to the response status of the receiving mobile terminal 11 returned from the mail server 13 instead of the receiving mobile terminal 11. The data may be transmitted to the receiving side portable terminal 11 via the mail server 13.

  Furthermore, in the case where the transmission side characteristic parameter is set to be transmitted in addition to the text data of the mail body, instead of transmitting the transmission side characteristic parameter in addition to the text data at the transmission side portable terminal 10, the reception side portable parameter is transmitted. The mail server 13 confirming the correspondence status of the reception-side portable terminal 11 using the terminal correspondence status registration table extracts the transmission-side feature parameter to be transmitted to the reception-side portable terminal 11 from the feature parameter registration table, and Along with the text data of the mail text received from the terminal 10, it can be transmitted to the receiving-side mobile terminal 11. Thus, after registering the transmission side characteristic parameter in the mail server 13, the transmission side portable terminal 10 does not need to transmit the transmission side characteristic parameter to the reception side portable terminal 11, and the transmission side characteristic parameter is not necessary. The correspondence status of the receiving mobile terminal 11 is confirmed except for the case where the data type of the document image is transmitted in addition to the text data of the mail body to the receiving mobile terminal 11 that cannot perform conversion corresponding to the feature parameter. Instead, it is better to send only text data in the mail body.

  Further, the mail server 13 uses the transmission side characteristic parameters registered in the characteristic parameter registration table to generate the text data of the mail body received from the transmission side portable terminal 10 in the original font characters for the sender. Server font generation means having the same function as the font generation section 2 and server document image generation means having the same function as the document image generation section 3 that generates a document image image using the original font. In this case, the mail server 13 uses the transmission side characteristic parameters extracted from the characteristic parameter registration table to generate the text data of the mail body received from the transmission side portable terminal 10 as server font generation means and server document image image creation. The converted document image. As the document data that reproduces the transmission-side original fonts, pictures, together with the text data of the received mail text, it is also possible to be transmitted to the recipient mobile terminal 11.

  Thus, the transmitting-side mobile terminal 10 can transmit only text data of the e-mail text regardless of the corresponding status of the receiving-side mobile terminal 11. After registering the response status for the transmission-side feature parameter in the reception-side mobile terminal compatibility status registration table of the mail server 13, it is necessary to hold the transmission-side feature parameter of the transmission-side mobile terminal 10 in the reception-side area of the storage unit 8. In addition, there is no need to provide the font generation unit 2 that generates the original font corresponding to the transmission-side characteristic parameter and the document image generation unit 3 that generates the document image.

FIG. 6 shows an example of the reception side portable terminal correspondence status registration table of the mail server 13 according to the present invention in which the correspondence status to the characteristic parameters of the reception side portable terminal 11 is registered.
In the reception-side mobile terminal compatibility status registration table of FIG. 6, “recipient” indicating the reception-side mobile terminal 11, “recipient mail address” indicating the mail address for the receiver of the reception-side mobile terminal 11, and transmission-side characteristics “Responding status” indicating whether or not a means for generating an original font corresponding to the parameter and converting it to a document image image is provided. When corresponding to the transmission side characteristic parameter, the transmission side characteristic parameter already received As “Received feature parameter ID” specifying the transmission side feature parameter held in the receiving side area of the storage unit 8.

  Here, in the reception-side portable terminal compatibility status registration table of FIG. 6, “Received feature parameter ID” corresponds to the ID shown in the feature parameter registration table of the feature parameter management server 12 shown in FIG. In the embodiment, the characteristic parameter registration table is also registered in the mail server 13 as described above, and both tables are associated with each other using the ID. In FIG. 6, each of “Recipient” is “Kanagawa”, “Tokyo”, “Tochigi”, and “Yamanishi”, as shown in “Correspondence Status”, the characters in the handwritten font are transmitted from the transmission side characteristic parameter. This indicates that the device is a compatible model having means for generating.

  Further, as shown in “Received feature parameter ID” in FIG. 6, when “Recipient” is “Kanagawa”, it is a compatible model for the transmission side feature parameter, but is stored in the reception side area of the storage unit 8. If the “recipient” corresponding to the model is “Tokyo”, the ID is “1”, that is, the “sender” shown in FIG. This indicates that the “Saitama font” file registered by “Saitama” is already held in the receiving-side area of the storage unit 8.

  When the “recipient” corresponding to the model is “Tochigi”, the ID is “0, 1, 2”, that is, “Takagi”, “Saitama”, “Ibaragi” of “sender” shown in FIG. Indicates that the registered “Takagi font”, “Saitama font”, and “Ibaragi font” files are already held in the receiving-side area of the storage unit 8, and the corresponding model “Reception” If the “user” is “Yamanishi”, the ID is “0, 1”, that is, “Takagi font” and “Saitama font” registered by “Takagi” and “Saitama” of “Sender” shown in FIG. It shows that each file is already held in the receiving area of the storage unit 8.

  When the mail server 13 receives the body data of the email from the sender mobile terminal 10 that is the sender, the mail server 13 uses, for example, the email address of the receiver mobile terminal 11 that is the destination of the received email as shown in FIG. Referring to the reception-side mobile terminal compatibility status registration table, whether or not the reception-side mobile terminal 11 is a compatible model corresponding to the transmission-side feature parameter is determined from the “response status” column, Using the e-mail address of the transmission source mobile terminal 10 of the transmission source, referring to the feature parameter registration table, the ID for identifying the transmission side characteristic parameter of the transmission mobile terminal 10 is extracted, and again using the extracted ID, With reference to the reception-side mobile terminal compatibility status registration table in FIG. 6, the reception-side mobile terminal 11 has already received the ID of the transmission-side feature parameter of the transmission-side mobile terminal 10 on the reception side of the storage unit 8. It determines whether to hold the band.

  Thus, by providing the reception side portable terminal correspondence status registration table as shown in FIG. 6, the mail server 13 allows the transmission side portable terminal 10 such as steps S1 and S2 in the data type selection processing flowchart of FIG. Since the data type of the e-mail corresponding to the receiving mobile terminal 11 can be selected immediately without performing the transfer process with the receiving mobile terminal 11, the mail server 13 is connected to the transmitting mobile terminal 10. The received e-mail can be quickly transmitted to the receiving-side mobile terminal 11 in the form of an e-mail having an appropriate data type.

  In the reception-side mobile terminal compatibility status registration table shown in FIG. 6, in order to identify the feature parameter held in the reception-side area of the storage unit 8 as the transmission-side feature parameter that has already been received, Although an example using an ID “parameter ID” is shown, when only one type of transmission-side characteristic parameter is held by each transmission-side mobile terminal 10, as described above, the characteristic parameter ID is used. Instead of registration, it is also possible to specify the transmission side characteristic parameter of the transmission side portable terminal 10 by registering using the transmission mail address or the sender name of the transmission side portable terminal 10. Further, the reception-side portable terminal compatibility status registration table shown in FIG. 6 and the feature parameter registration table shown in FIG. 1 may be configured as a single table.

  In addition, in the case of registering using the transmission mail address or sender name of the transmission-side portable terminal 10 instead of the “received characteristic parameter ID”, the transmission-side form terminal 10 has a plurality of characteristic parameter files. If the transmission mail address and the sender name are different for each feature parameter file, the plurality of feature parameter files of each transmission-side mobile terminal 10 are further included in the reception-side mobile terminal compatibility registration table. Which is stored in the receiving-side area of the storage unit 8 is additionally registered for each transmitting-side mobile terminal 10 and the transmitting-side mobile terminal 10 transmits an e-mail. At this time, in addition to the text data of the mail body, information on the identifier specifying the feature parameter file to be used is also sent to the mail server 13. It may be trust.
