Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a character input conversion device that converts character input with reference to a dictionary, and more particularly to a character input conversion device used in a mobile terminal device.
[0002]
[Prior art]
Generally, a portable terminal device such as a mobile phone has an e-mail transmission / reception function. When a user inputs a kana character using a character input conversion device when transmitting an e-mail, the character input conversion device uses a kana character. When a character string such as a word corresponding to a kana character is sequentially displayed on the display unit with reference to a dictionary or the like in response to the input of the character, and the user selects a desired one from the displayed kana character string, the kana character Is converted to the selected character string (normal character conversion function).
[0003]
By the way, in the character input conversion device, the display order of the character strings to be displayed in response to the input of the kana characters is defined in advance, and therefore, a desired character string may not be displayed on the display unit easily. Makes it difficult to search for a character string. To deal with such problems, the character string selected by the user is automatically registered as a conversion candidate in association with the input kana character, and the same kana character is input when a new kana character is input. Then, there is what is called a learning function that reduces the troublesomeness of character input conversion by making the display order of registered conversion candidates faster so that a desired character string can be searched early. There is also a usage frequency conversion function that increases the counter value each time a conversion candidate is used, and displays the conversion candidates in descending order of conversion candidates with the same counter value when the same kana character is input next time. . Furthermore, there is a predictive conversion function that predicts a character string and displays conversion candidates when a part of a kana character is input.
[0004]
On the other hand, when an e-mail is transmitted, a signature such as an address, name, or e-mail address is added to the e-mail and transmitted. For example, signature data is added or not added when character information is transmitted. If set, there is one that notifies / not-notifies the caller ID according to the addition / non-addition setting of the signature data. As this signature data, the address, name, email address, company name, title, age There is one that includes at least one of hobbies (see Patent Document 1).
[0005]
[Patent Document 1]
JP 2001-318858 A (paragraph (0005) to paragraph (0009), FIGS. 1 and 2)
[0006]
[Problems to be solved by the invention]
By the way, in the character strings whose conversion candidate display order is handled earlier by the learning function or the use frequency conversion function, these conversion candidates are character strings that are frequently used by the user. Even if the display order of a specific character string is accelerated by the learning function or the use frequency conversion function as described above, the search itself is easy, but it is easily displayed as a conversion candidate for humans other than the user. Therefore, there is a problem that the character string is browsed and information on the privacy of the user is easily leaked.
[0007]
Such a leakage of privacy has a function of sending at least one of address, name, e-mail address, company name, title, age, and hobby as signature data to the other party as in Patent Document 1. Of course, this also occurs in the terminal device. In other words, Patent Document 1 does not protect against leakage of signature data, and there is a problem that signature data related to user privacy may be leaked to a person other than the sender and the receiver.
[0008]
An object of the present invention is to provide a character input conversion device that can register character strings as conversion candidates in accordance with input of kana characters and prevent leakage of these conversion candidates.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be exemplarily described in detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. This is just an example.
[0018]
Referring to FIG. 1, the character input conversion device according to the present invention is used for a mobile communication terminal device such as a mobile phone, for example. An information processing apparatus having a function of sequentially displaying character strings with reference to a dictionary and performing character input conversion on input of the kana characters when a user selects a desired character string from the displayed character strings Can also be used.
[0019]
The illustrated mobile communication terminal device includes a transmission / reception unit 11, a control unit 12, a determination unit 13, a storage unit 14, a display unit 15, an operation unit 16, and a character conversion unit 17, and the transmission / reception unit 11 includes an antenna 11 a. Is provided. The operation unit 16 has a plurality of operation keys and character input keys (both not shown), and the control unit 12 responds to the operation of the operation keys or character input keys as described later by the transmission / reception unit 11 and the determination unit 13. The storage unit 14, the display unit 15, and the character conversion unit 17 are controlled.
[0020]
First, general operations when a user tries to send an e-mail will be described. When the mail transmission mode is selected by the operation key, the control unit 12 displays a character input screen on the display unit 15. When the user inputs a kana character using the character input key, the character conversion unit 17 displays a character string corresponding to the input of the kana character sequentially with reference to a dictionary (not shown) according to the input of the kana character. To do.
[0021]
When the user operates the operation key to select / determine a desired character string, the control unit 12 determines the character string as the selected character string. In this way, the user sequentially inputs kana characters, selects a character string, and completes the outgoing mail text. When the outgoing mail text is completed, the user operates the operation keys to specify the mail destination. When the transmission button is pressed, the control unit 12 controls the transmission / reception unit 11 to transmit the transmission mail document to the destination via the antenna 11a.
[0022]
When the received mail is received by the transmission / reception unit 11 via the antenna 11a, the control unit 12 displays the received mail on the display unit 15.
[0023]
By the way, if a character string that is frequently used by the user is registered in advance as a conversion candidate and an input of a kana character is performed at the time of e-mail transmission, a search can be made from the conversion candidate. Can be searched easily and quickly. Here, with reference to FIG.1 and FIG.2, operation | movement when a user performs conversion and registration of kana character input is demonstrated.
[0024]
When the user registers a character string as a conversion candidate, when the kana character is input as described above, the control unit 12 stores a conversion candidate described later in the storage unit 14 for the input kana character. It is checked whether or not it is registered. If it is not registered, the control unit 12 activates the character conversion unit 17, and the character conversion unit 17 refers to the dictionary and displays a character string on the display unit 15. Then, the user selects a desired character string from the character strings displayed on the display unit 15 (step S1: character conversion operation).
[0025]
When a character string is selected in this way, the control unit 12 controls the determination unit 13 to determine whether or not the secret mode is on (step S2: secret mode). This secret mode is set by, for example, an operation key (secret key), and it is necessary to input a personal identification number (ID number) when canceling the setting of the secret mode. That is, here, the operation unit 16 and the control unit 12 are mode setting means.
[0026]
When it is determined that the secret mode is on (second mode), the control unit 12 adds a secret flag to the selected character string and registers the selected character string in the storage unit 14 as a special conversion candidate (secret conversion candidate). (Step S3: Secretization registration). On the other hand, if the determination unit 13 determines that the secret mode is off (first mode), the control unit 12 registers the selected character string in the storage unit 14 as a normal conversion candidate as it is. (Step S4: normal registration).
[0027]
For example, as shown in FIG. 3 (a), when the secret mode is turned off and the sentence “The cherry blossoms are in full bloom in Kyoto Park seen from the classroom” is edited, It is determined that the secret mode is off, and the control unit 12 stores “today”, “weather”, “classroom”, “visible”, “Kyoto Park” in the storage unit 14 as shown in FIG. The character strings “Sakura” and “I am in full bloom” are registered in the storage unit 14 as normal conversion candidates in association with respective readings (that is, kana characters). In FIG. 3B, a cross mark is a non-secret registration flag indicating non-secret registration.
[0028]
On the other hand, assuming that the user is a character string related to privacy, the secret mode is selectively turned on, and as shown in FIG. 3 (c), the text “Today, Kyocera Materials Kyocera Taro Kyocera will deliver Δ △ parts” 3, the determination unit 13 determines that the secret mode is on, and the control unit 12 stores “Kyocera Materials”, “Kyocera Taro”, “Kyocera Materials” in the storage unit 14 as illustrated in FIG. The character strings “ΔΔ parts” and “delivery schedule” are additionally registered in the storage unit 14 as secret conversion candidates in association with the respective readings. In FIG. 3D, a circle mark is a secret registration flag indicating secret registration.
[0029]
Next, referring to FIG. 4, when a kana character is input from the operation unit 16, the control unit 12 searches the storage unit 14 and activates the kana character input before starting the character conversion unit 17. It is checked whether or not the conversion candidates (secret conversion candidates and normal conversion candidates) exist in the storage unit 14 (step S5: character conversion operation). When the conversion candidate exists in the storage unit 14, the control unit 12 controls the determination unit 13 to determine whether or not the secret mode is on (step S6: secret mode).
[0030]
When it is determined that the secret mode is on, the control unit 12 reads out all conversion candidates (secret conversion candidates and normal conversion candidates) corresponding to the kana character input and displays them on the display unit 15 (step S7). ). When the secret mode is on, only secret conversion candidates may be displayed.
[0031]
On the other hand, if it is determined that the secret mode is off, the control unit 12 reads out the normal conversion candidate corresponding to the kana character input and displays it on the display unit 15 (step S8). If there is no conversion candidate corresponding to the input of the kana character in the storage unit 14, the character conversion unit 17 is activated to convert the kana character as described above, as described in FIG. Thus, registration in the storage unit 14 is performed.
[0032]
For example, when the secret mode is turned off and “Kyo” is input from the operation unit 16, the determination unit 13 determines that the secret mode is off, and the control unit 12 displays “ Character strings “today”, “classroom”, and “Kyoto park” (that is, normal conversion candidates) to which a non-secret registration flag having a reading “Kyo” is assigned are displayed on the display unit 15.
[0033]
On the other hand, when the secret mode is turned on and “Kyo” is input from the operation unit 16, the determination unit 13 determines that the secret mode is on, and the control unit 12 displays “ Non-secret registration flag with the reading “Kyo” and the character strings “Today”, “Classroom”, “Kyoto Park”, “Kyocera Materials”, and “Kyocera Taro” (ie, the secret conversion) Candidates and normal conversion candidates) are displayed on the display unit 15.
[0034]
In this way, if the secret mode is turned on and the character string is registered as a secret conversion candidate, and then the secret mode is turned off, the secret conversion candidate is not displayed on the display unit 15, and therefore an ID number is assigned. If a person other than the user is in a secret state, even if the kana character input is converted, secret conversion candidates cannot be displayed, and privacy-related information is prevented from leaking outside. It will be possible.
[0035]
Next, registration of conversion candidates when performing e-mail creation and transmission will be described with reference to FIGS. 1 and 6. The storage unit 14 defines a destination information storage area, and a plurality of pieces of destination information including at least an electronic mail destination are stored in the destination information storage area. As described above, when the user transmits a kana character when sending an e-mail, the control unit 12 determines whether or not conversion candidates are registered in the storage unit 14 for each mail destination as described later. If the conversion candidate is not registered, the control unit 12 activates the character conversion unit 17, and the character conversion unit 17 refers to the dictionary and displays the character string on the display unit 15.
[0036]
Then, the user selects a desired character string from the character strings displayed on the display unit 15 (step S9: character conversion operation). When the character string is selected in this way, the control unit 12 controls the determination unit 13 to determine the destination of the mail (step S10: destination).
[0037]
The user can decide whether or not to secretly convert the conversion candidate according to the destination. When the destination is set, the control unit 12 automatically sets the conversion candidate corresponding to the destination as a secret conversion candidate ( That is, when the destination setting is performed, the control unit 12 turns on the secret mode (as the second mode) and sets the conversion candidate corresponding to the destination as the secret conversion candidate).
[0038]
As a result, the conversion candidate with the destination set becomes a secret conversion candidate, and the conversion candidate without the destination set becomes a normal conversion candidate (that is, if the destination setting is not performed, the control unit 12 turns off the secret mode). (As a first mode) the conversion candidate corresponding to the destination is set as a normal conversion candidate). In the illustrated example, conversion candidates corresponding to the destinations “A” and “B” are secret conversion candidates, and conversion candidates corresponding to other destinations (that is, destinations are not set) are normal prediction conversion candidates. It shall be.
[0039]
If it is determined in step S10 that the destination is the destination “A”, the control unit 12 adds a secret registration flag to the selected character string, and stores it in the storage unit 14 as a secret conversion candidate for the destination “A”. Register (step S11: destination “A” secret registration). If it is determined in step S10 that the destination is the destination “B”, the control unit 12 assigns a secret registration flag to the selected character string and stores it as a secret conversion candidate for the destination “B”. 14 (step S12: destination “B” secretization registration).
[0040]
On the other hand, if the determination unit 14 determines that the destinations are not the destinations “A” and “B”, the control unit 12 registers the selected character string in the storage unit 14 as a normal conversion candidate as it is ( Step S13: Normal registration).
[0041]
For example, when an e-mail is created and edited as shown in FIG. 3A without specifying a destination, the character string shown in FIG. 3B is registered in the storage unit 14 as a normal conversion candidate. (Here, the x mark indicates that no destination is specified).
[0042]
On the other hand, when the e-mail creation / editing is performed as shown in FIG. 3C with the mail destination as the destination “A”, the character string shown in FIG. 3D is stored in the storage unit 14 for the destination “A”. Are added and registered as secret conversion candidates (in this case, a circle indicates that it is a secret prediction conversion candidate for the destination “A”).
[0043]
Next, referring to FIG. 7, as described above, when the kana character is input from the operation unit 16 at the time of e-mail creation (step S14: character conversion operation during mail creation), the control unit 12 performs character conversion. Before starting the unit 17, the storage unit 14 is searched to check whether or not a conversion candidate corresponding to the kana character input exists in the storage unit 14 for each mail destination (step S 15: destination). .
[0044]
If the mail destination is “A”, the determination unit 13 determines that the mail destination is set to the seek mode on (second mode), and the control unit 12 accesses the storage unit 14. The conversion candidate (secret conversion candidate) corresponding to the input of the kana character is read from the conversion candidate for the destination “A”, the conversion candidate is displayed on the display unit 15 and the normal conversion candidate (destination-designated non-conversion candidate) is displayed. The normal conversion candidate corresponding to the input of the kana character is read and displayed on the display unit 15 (step S16).
[0045]
Similarly, if the mail destination is the destination “B”, the determination unit 13 determines that the mail destination is set to the seek mode ON, and the control unit 12 accesses the storage unit 14 to access the destination “B”. The conversion candidate corresponding to the kana character input (secret conversion candidate) is read out from the conversion candidate for “”, and the conversion candidate is displayed on the display unit 15 and the normal conversion candidate corresponding to the kana character input is read out from the normal conversion candidate Is displayed on the display unit 15 (step S17).
[0046]
As described above, since the conversion candidates for the destinations “A” and “B” are secret conversion candidates, of course, if the secret mode is off, the conversion candidates are not read out from the storage unit 14, and are therefore displayed. It is not displayed on the part 15.
[0047]
If the mail destination is not “A” or “B”, the determination unit 13 determines that the mail destination is set to the secret mode off (first mode), and the control unit 12 stores the storage unit 14. , The normal conversion candidates corresponding to the input of kana characters are read from the normal conversion candidates, and the normal conversion candidates are displayed on the display unit 15 (step S18).
[0048]
For example, when mail creation / editing is performed without specifying a mail destination, if “Kyo” is input from the operation unit 16, the determination unit 13 determines that there is no destination (others), and the control unit 12 As shown in FIG. 5A, the display unit 15 uses the character strings “Today”, “Classroom”, and “Kyoto Park” to which “no addressee” having a reading “Kyo” is assigned as a conversion candidate. To display.
[0049]
On the other hand, when the mail address is designated as the address “A” (in this case, the secret mode is turned on), and “K” is input from the operation unit 16 when performing mail creation / editing, the determination unit 13 The mail destination is determined to be the destination “A”, and the control unit 12 converts the destination “A” and the destination “A” having the reading “cho” as shown in FIG. Candidates are displayed on the display unit 15 (only the conversion candidates for the destination “A” may be displayed).
[0050]
In this way, since the conversion candidate is secretized and registered according to the destination, when the destination is designated, the secret conversion candidate is not displayed on the display unit 15 unless the secret mode is turned on. Therefore, it is possible to prevent a person other than the user to whom the ID number is assigned from browsing the secret conversion candidate and leaking information related to privacy to the outside. Furthermore, since conversion candidates are registered for each destination, conversion candidate search can be speeded up.
[0051]
By the way, the character conversion unit 17 is provided with a usage frequency counter (not shown). For example, at the time of mail creation / editing (that is, at the time of kana character conversion), for each conversion candidate selected from the storage unit 14. The frequency of use is counted, and the display order when the conversion candidates are displayed on the display unit 15 is changed according to the count value.
[0052]
Here, regarding the secret conversion candidate, the use frequency is counted every time the secret mode is turned on / off. As a result, the secret conversion candidate is not easily displayed on the display unit 15 when the secret mode is off.
[0053]
As is clear from the above description, the control unit 12, the determination unit 13, the storage unit 14, the display unit 15, the operation unit 16, and the character conversion unit 17 function as a character input conversion device. Moreover, the control part 12 and the determination part 13 function as a control means. Further, the storage unit 14 functions as a destination information storage unit and a storage unit.
[0054]
The above-described secret mode is, for example, a mode in which display is prohibited for a communication partner designated in advance as a secret mode when displaying a list of address information such as the name, telephone number, and mail address of a registered communication partner. It is. In addition, secret settings can be made for each address book. In any case, as the secret, a predetermined personal identification number is input, and only when the coincidence is obtained, the entire address book can be displayed. This is a function that acts as if such address information is not registered in the address book when no match is found. Furthermore, such secret settings may be made for mail transmission / reception and outgoing / incoming call history.
[0055]
【The invention's effect】
As described above, according to the present invention, if the secret mode is turned on (that is, the first mode) or the destination is not specified, a special conversion candidate (secret conversion candidate) is output to the output unit. It is not output, and a person other than the user cannot view the converted conversion candidate. As a result, there is an effect that information relating to the user's privacy can be prevented from leaking outside.
