Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character conversion method for a mobile terminal, and more particularly to a character conversion method and a mobile terminal which can reduce input operations without requiring switching of input modes.

[0002]

2. Description of the Related Art In recent years, a mobile terminal such as a mobile phone or an electronic notebook has a plurality of input modes for inputting kanji, kana and the like. For example, kanji, kana, katakana, half-width katakana, full-width alphabet, half-width alphabet, full-width lower case, half-width lower case, symbol, full-width numeral, half-width numeral. Normally, these input modes are sequentially switched by pressing a designated key (hereinafter referred to as "mode switching key").

In the conventional portable terminal, the data of the entered key is converted into characters according to the set input mode among a plurality of input modes. To change the type, you have to switch the input mode.

For example, when it is desired to partially input half-width alphabetic characters in the kanji mode, the mode switching key is pressed a required number of times to switch to the half-width alphabetic mode, the half-width alphabetic character is input, and then the half-width alphabetic character is input again. It was supposed to press the mode switching key. In this way, no matter where the Kanji mode and the half-width alphabetic mode are set in the mode switching order, the mode switching key must be pressed once to change the input mode and return to the original mode.

Here, a conventional character conversion method in a portable terminal will be described with reference to FIG. FIG. 7: is explanatory drawing which shows the character conversion method in the conventional portable terminal. Figure 7
As shown in, when entering the character string "Motomachi 21KO Building Underground" on a conventional mobile terminal, first enter "Motomachi" in Kanji mode and press the conversion key 31 to select "Motomachi."".

Next, the mode switching key is pressed four times to switch to the numeric mode and "21" is input. Then, press the mode switch key four times to switch to English mode,
Enter "KO". Then, the mode switching key is pressed again three times to switch to the half-width kana mode, "bill" is input, and finally the mode switching key is pressed three times to return to the kanji mode and "underground" is input. In this way, the character string "Motomachi 21 KO underground" is input in 53 steps.

As a conventional technique for facilitating character input on a mobile terminal, Japanese Patent Laid-Open No. 11-39126 "Mobile Terminal" published on February 12, 1999 (applicant: Kokusai Electric Co., Ltd., inventors: Kazuhiro Tsutsumi) This prior art is
The control unit has an area for storing the number of input characters, and the control unit increments and updates the stored number of input characters each time a character is input, and updates the stored number of input characters when backspace is input. Decrement and update,
A portable terminal that outputs and displays the updated number of input characters on the display unit, and does not need to count the number of input characters when transmitting a message, and facilitates message input work.

[0008]

However, the mobile terminal is usually set in the kanji mode and used in many cases. In the conventional mobile terminal, the user is enthusiastic about inputting mail and forgets to change the input mode to change the character. If you make a mistake,
It is necessary to delete the input characters once and then press the mode switching key again and again to input again, which is a troublesome and inconvenient re-input operation.

The present invention has been made in view of the above circumstances, and even if the user performs an input operation in an incorrect input mode,
You can display the same conversion candidates that you entered in the correct input mode without performing the delete and re-input operations.
An object of the present invention is to provide a character conversion method and a mobile terminal that can input a desired character with few operations and improve convenience.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. The character conversion method and the mobile terminal according to the present invention store numerical data input by key operation, and display a conversion candidate in the set input mode every time the conversion key 31 is pressed, and display it separately. When there are no more conversion candidates, the input mode is switched in the preset order and the conversion candidates corresponding to the numerical data are displayed. You can enter the desired character without switching the input mode. Even if you forget to switch the mode and enter a character, the conversion candidates in the correct input mode can be displayed, and you can improve convenience by eliminating the need to delete or re-enter the character. is there.

The configuration of the mobile terminal according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a configuration block diagram of a mobile terminal (this device) according to an embodiment of the present invention. A mobile phone will be described as an example of the mobile terminal. As shown in FIG. 1, the mobile terminal of the present embodiment controls a communication circuit unit 1 that performs signal processing and data conversion associated with a telephone call or data communication, and a user interface unit such as an operation unit 3 and a display unit 5. And a control unit 2 for controlling input / output of data to / from the communication circuit unit 1 and the storage unit 4.
An operation unit 3 having a plurality of input keys such as an off-hook key, an on-hook key and a numeric keypad for a user to input data, a storage unit 4 for storing a control program in the control unit 2, telephone directory data and the like, and a control unit The display unit 5 displays various data in accordance with the instruction from 2.

Further, the operation section 3 is provided with a conversion key 31 for inputting an instruction to convert input data and display a conversion candidate, as in the conventional case. The input keys for inputting characters provided on the operation unit 3 are for inputting corresponding numeric data.

In particular, in this apparatus, the operation of the control unit 2 when the conversion key 31 is pressed during character input is partly different from the conventional one. Although a mobile phone will be described as the mobile terminal according to the embodiment of the present invention, the communication circuit unit 1 is not necessary if the mobile phone does not have a communication function such as an electronic notebook.

Further, in the storage unit 4, as in the conventional case, the input character table 4 for associating the input keys of the operation unit 3 with the characters input when each key is pressed for each input mode.
1, and further stores a kanji conversion candidate 42 as a dictionary for converting data input in the kanji mode into kanji or kana (hiragana, katakana).

The storage unit 4 also stores a mode switching order when switching the input mode. The input mode switching order is used as the switching order when switching the input mode set by the operation from the operation unit 3 as in the conventional case, and is a feature of the present device, and is controlled by the control unit 2 described later. It is also used as a switching order when switching.

Here, the input character table 41 of the storage unit 4
Will be described with reference to FIG. FIG. 2 is an explanatory diagram of the input character table 41 stored in the storage unit 4. As shown in FIG. 2, the input character table 41 stores the input keys and the characters assigned to them for each input mode, as in the conventional case, and serves as a reference for character conversion. It is a thing.

In the case of FIG. 2, numeric keys from "1" to "0" are used as input keys used for character input.
There are "*" and "#" symbol keys, which indicate that each input key is converted into a different character depending on the input mode.

For example, when the "1" key is pressed in the kanji mode, the conversion candidates cyclically change like "a → i → u → e → o → a → ...". In addition, even with the same "1" key, in English mode ". → / → @ →-→ _ →. →…"
In the number mode, the conversion candidates are different depending on the input mode, such as "1" being input.

When the kanji mode is set,
Conversion key 31 for the input Hiragana conversion candidates
Every time is pressed, the conversion candidates of kanji (or kanji mixed with kanji) are displayed according to the kanji conversion candidates 42.

The control unit 2, which is a characteristic part of the present apparatus, stores the input mode currently set in the work area and performs character conversion according to the input mode. In the related art, the control unit 2 only switches the input mode in response to an instruction from the setting operation unit 3, but as a feature of the present device and method, the control unit 2 itself switches the input mode. .

Further, when a character is input from the operation unit 3, the control unit 2 converts the character corresponding to the numerical data based on the numerical data input by pressing the key and the set input mode. When the confirmation output (not shown) of the operation unit 3 is pressed and output to the display unit 5 as a candidate,
The displayed conversion candidates are confirmed. The control unit 2 includes a work area (storage area) for temporarily storing numerical data corresponding to the input keys. Further, the confirmation data is stored in a specific area (confirmation area) of the storage unit 4 (not shown).

Even when the conversion key 31 is pressed and then the input key for inputting a character is pressed while the conversion candidates are displayed, the control unit 2 performs the finalizing operation. It is determined that the conversion candidate is decided.

Specifically, the control unit 2 stores numerical data corresponding to the key (input key) pressed by the operation unit 3, and when the conversion key 31 is pressed, first, the series of Is converted according to the currently set input mode, and the conversion candidates are displayed on the display unit 5. Each time the conversion key 31 is pressed, if there is another conversion candidate, it is sequentially displayed.

As a feature of this apparatus, when there is no other conversion candidate in the input mode, the control unit 2
The input mode is switched and set according to the mode switching order stored in the storage unit 4, and the conversion candidates in the switched input mode are sequentially displayed.

When the conversion candidates are confirmed,
The control unit 2 stores the finalized data in the finalized area of the storage unit 4 and returns the input mode to the original setting.

For example, in the most frequently used Kanji mode, the control unit 2 of this apparatus holds numerical data corresponding to the input key in the work area, and when the conversion key 31 is pressed, first, The numeral data held in the storage area is converted into kanji (kanji and kana mixture conversion) by referring to the kanji conversion candidate 41 of the storage part 4. When there are a plurality of conversion candidates, the control unit 2 sequentially displays the conversion candidates each time the conversion key 31 is pressed.

When all the Kanji conversion candidates have been displayed, they are not confirmed, and when the conversion key 31 is pressed next, the input modes are sequentially changed in accordance with the mode switching order preset in the storage unit 4. The conversion candidate is selected by switching.

Specifically, when the conversion key 31 is further pressed after all the conversion candidates in the kanji mode are displayed, the control unit 2 displays "Kanji → full-width kana → half-width kana → alphabet → number →
The conversion mode is sequentially switched to display conversion candidates, such as "Kanji → ...".

When a mode other than the Kanji mode is set, the control unit 2 immediately sets the next input mode and displays the conversion candidates when a character is input and the conversion key 31 is pressed. It is like this.

Here, the character conversion method in this apparatus will be described with reference to FIG. 3 together with the user's operation and the contents of the storage area of the control unit 2. FIG. 3 is an explanatory diagram showing operations and display contents and contents of the storage area when a numeral is input in the Kanji mode using the present device. The example of FIG. 3 shows an example of conversion in the case where “09012345678” is input in the kanji mode.

As shown in FIG. 3, when the user inputs "09012345678" in the Chinese character mode, the control unit 2 holds the numerical data of "09012345678" in the storage area according to the input key. There is. Then, the control unit 2 outputs a conversion candidate based on the currently set Chinese character mode to the display unit 5, and "Warawaka Tanahama" is displayed as the conversion candidate.

Since this conversion candidate is not a character string that the user wants to input, the user presses the conversion key (first time) to display the next conversion candidate. Here, the control unit 2
If it is determined that there is no next kanji conversion candidate corresponding to "Warawaka Tanahama" by referring to the kanji conversion candidate 42 in the storage unit 4, the input mode is switched in a preset order and the conversion candidate is displayed.

In the example of FIG. 3, when the conversion key (first time) is pressed, the control unit 2 stores "0" stored in the storage area.
For the data of "9012345678", the input mode is set to the full-width Kana mode, and the conversion candidate "Warawa Akasata Nahama" according to the full-width Kana mode is displayed on the display unit 5. Further, as described above, in the present apparatus, the switching order of the input modes is “Kanji → Full-width Kana → Half-width Kana → English letters → Numbers → Kanji → ...”.

Then, by pressing the conversion key (second time), the control unit 2 switches the input mode to the next half-width kana mode, displays the conversion candidate "Warawa Akasata Nahama", and further presses the conversion key (third time). Then, switch to the next alphabet mode, display the conversion candidate "OwO.adgimpt", and press the conversion key (4
By pressing the (second) time, the mode is switched to the number mode and the conversion candidate "09012345678" is displayed.

When the user presses the enter key, the control unit 2 displays the conversion candidate "09012345" displayed.
678 ”is stored in a specific area (fixed area) of the storage unit 4, and the storage area in the control unit 2 is cleared.

Then, the control unit 2 returns the input mode to the initially set Kanji character mode. In this way, the character conversion method in this device is performed.

As a result, in this apparatus, even if the user inputs in the wrong input mode, the control unit 2
Based on the numerical data stored in the storage area, the input mode is sequentially switched to display the conversion candidates, so that the desired characters can be displayed as the conversion candidates with a few operations without deleting or re-inputting. Therefore, it is possible to improve usability.

Further, in this apparatus, even if the input mode is switched and the conversion candidates are displayed, if the conversion candidates are confirmed, the input mode is returned to the original state. It is possible to return to the Kanji mode that was initially set without doing so, which is convenient for immediately entering Kanji or Kana after entering "09012345678" such as "Call 09012345678".

As a result, the user can input various types of characters without having to be aware of the input mode at all, and the convenience can be greatly improved.

Next, as a similar example, regarding a conversion example when "Hello" is input in the kanji mode,
This will be described with reference to FIG. Figure 4 shows "He
It is explanatory drawing which shows the operation, the display content, and the content of a storage area when "llo" is input. As shown in FIG. 4, when "Hello" is entered in the Chinese character mode, the numerical data "444443355 is stored in the storage area of the control unit 2.
5R555666 ”is stored, and the display unit 5 displays“ Toshinufu ”which is a conversion candidate in the Kanji mode. Note that the numeric data also includes cursor data such as "R" and symbols such as "*" necessary for identifying a character.

Here, when the conversion key (first time) is pressed, the control unit 2 checks whether or not there is a kanji conversion candidate corresponding to "Tinunufu", and confirms that there is no kanji conversion candidate. Switch to full-width Kana mode, which is the next input mode, display the conversion candidate "Toshinufu", and then press the next conversion key
Press the second time) to switch to half-width Kana mode, display the conversion candidate “Toshinu”, and when the conversion key (second time) is pressed, switch to English mode and convert corresponding to “4444433555R555666” stored in the storage area. Display the candidate "Hello".

Then, when the confirmation key is pressed, the control unit 2 transfers the confirmation data to the storage unit 4 to clear the storage area and sets the input mode to the first Kanji mode. The operation of this device is performed in this manner.

Next, the character conversion processing in the control unit 2 of this apparatus will be described with reference to FIG. FIG. 5 is a flowchart showing the processing in the control unit 2 of the present device.
As shown in FIG. 5, when a character input key such as a numeric key is pressed (100), the control unit 2 stores the input numeric data in the storage area (102) and follows the set input mode. The conversion candidates are displayed (104).

Then, the control unit 2 confirms whether or not the confirm key has been pressed (106), and if not pressed, the control unit 2 confirms whether or not the conversion key 31 has been pressed (108). ), If the conversion key 31 is not pressed, the process proceeds to step 100 and waits for the next character input key to be pressed.

When the conversion key 31 is pressed in the process 108, the control unit 2 checks whether there is a next conversion candidate in the currently set input mode (1
10) If there is a next conversion candidate, the next conversion candidate is displayed (112).

When there is no other conversion candidate based on the set input mode in the process 110, the control unit 2
The input mode is switched to the next input mode according to the mode switching order set in advance in the storage unit 4, the conversion candidates based on the switched input mode are displayed (120), and the process 106 is entered.

When the confirm key is pressed in the process 106, the process proceeds to the process 130 and the displayed conversion candidates are stored in the confirmed area of the storage unit 4 as confirmed data (130) and stored. The area is cleared (132), and the input mode is returned to the input mode in the processing 104 (1
34) The process ends.

Although not shown here, the process 10 is performed.
In the case of shifting to No. 6, even if the enter key is not pressed, if the next character input key is pressed, it is determined in the same manner as the press of the enter key, and the displayed conversion candidate data is stored in the storage unit 41. In the confirmation area, the processings 130 to 134 for confirming the conversion candidates are performed, and the next processing is started from the processing 100 according to the input key. In this way, the processing in the control unit 2 of this device is performed.

Next, the operation of inputting a character string in which Chinese characters, Kana, English characters, and numbers are mixed using the portable terminal according to the embodiment of the present invention will be described with reference to FIG. Figure 6
FIG. 4 is an explanatory diagram showing user operations and display contents and contents of a storage area (storage area) when a character string in which kanji, kana, English characters, and numbers are mixed using the mobile terminal. In FIG. 6, a case where the character string “Motomachi 21 Building Underground” is input in the Kanji mode will be described as an example.

As shown in FIG. 6, in this apparatus, when "motomachi" is input and the conversion key 31 is pressed while the kanji mode is set, the control section 2 causes the kanji conversion. With reference to the candidate 42, “Motomachi” is displayed as a conversion candidate. Then, when the key "2" corresponding to the next input character is input when "Motomachi" is displayed, "Motomachi" is stored in the definite area of the storage unit 41 as definite data without pressing the definite key. Then, the storage area (storage area) of the control unit 2 is cleared.

When inputting "21", the user inputs "21" as it is without switching the mode. Then, when the conversion key 31 is pressed, "21" is displayed as the conversion candidate in the numerical mode in the fourth conversion candidate.

Next, in order to input "KO", the user inputs "KO" while keeping the input mode unchanged, and when the conversion key 31 is pressed, the conversion candidate "KO" in the alphabet mode is obtained by the third conversion. Is displayed. Similarly, the user inputs data regardless of the type of character and presses the conversion key 31 to display the conversion candidates when the control unit 2 sequentially switches the input modes and displays the desired character string. The operation of inputting and returning to the kanji mode when confirmed is repeated.

In this way, in the character conversion method of this apparatus, the input of "Motomachi 21 KO underground" is completed in 48 steps. Comparing this with the conventional character conversion method shown in FIG. 7, it is possible to input the same character string by an operation that reduces the number of steps by 5, and the user does not have to consider the input mode at all, and the desired character can be input with a small operation. You can enter columns.

According to the character conversion method and the portable terminal according to the embodiment of the present invention, when the specific mode is set, the control unit 2 holds the numerical data input by pressing the key and converts the numerical data. Each time the key 31 is pressed, the conversion candidates corresponding to the numerical data in the input mode are sequentially displayed. When there is no new conversion candidate even if the conversion key 31 is pressed, each time the conversion key 31 is pressed In addition, since the character conversion method and the mobile terminal display the conversion candidates corresponding to the numerical data by sequentially switching the input modes in accordance with the preset order, the user can perform various operations without switching the input mode by key operation. You can enter different types of characters, eliminating the need for input mode switching operations and deletion and re-input operations due to forgetting to switch input modes. It is possible to enter the Nozomu of character,
There is an effect that convenience can be improved.

In the present embodiment, the conversion candidates are displayed by switching to the next input mode only after all the conversion candidates in the set input mode are displayed. In addition, by pressing a specific key (for example, a function key or shift key) and the conversion key simultaneously or consecutively, even if there are conversion candidates for the input mode that have been set, you can switch to the next input mode. The conversion candidates may be displayed. By doing so, the number of user operations can be further reduced.

Further, in the present method and the present portable terminal, when there are no conversion candidates according to the “set input mode” stored in the control unit 2, the “set input mode” is input next. Although it is updated in the mode, as another method and device, the “input mode used for conversion” is stored separately from the “set input mode” set by the user in the control unit, and the “convert "Input mode used for conversion" is set to the same as "set input mode", and when there are no conversion candidates in that mode, the next input mode is set as "input mode used for conversion". It is also possible.

In this case, the "set input mode"
Is set by the user and does not change during the process. That is, if the kanji mode is set, the apparent input mode remains the kanji mode even when the conversion candidates of other input modes are displayed. And
When the conversion candidate is confirmed, the control unit may reset the “input mode used for conversion” to the same mode as the “set input mode”.

Even with another method and apparatus, different types of characters can be displayed as conversion candidates without the user performing a mode switching operation, and the number of user operations can be reduced and convenience can be improved. It is a thing.

In order to simplify the explanation,
Although the mode switching order stored in the storage unit 4 is assumed to be fixed, the mode switching order is stored in a rewritable storage element, and the user can arbitrarily rewrite it by an operation from the operation unit 3. You may be allowed to do so. In this case, a screen such as “mode switching order setting” is provided, and the control section 2 updates the mode switching order of the storage section 4 according to an instruction from the operation section 3. In this way, the user can set the mode switching order in the order that he or she frequently uses it, can further reduce the operations, and is particularly effective when the number of modes is large.
