  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram schematically showing the appearance of a mobile phone as an example of an embodiment of the present invention. As shown in FIG. 1, the mobile phone 1 is provided with a display 11 and keys 12. The display 11 is configured by a liquid crystal display or an organic EL display, and displays a screen according to the operation status of the mobile phone 1.

  The key 12 includes a character input key 12a for inputting numbers, characters and symbols, and a function key 12b used for operations such as activation and termination of application software. In the character input key 12a, characters of different character types such as numbers, kana characters, and alphabets are assigned to one key, and the character input key 12a is used in accordance with a predetermined operation using the function key 12b. The character type that can be entered is switched. In addition, a plurality of characters of the same character type may be assigned to one character input key. For example, the character input key “2” is assigned five characters “kana line”. A plurality of characters of the same character type assigned to one character input key can be switched by successively pressing the key.

  FIG. 2 is a block diagram showing an internal configuration of the mobile phone 1 of the present embodiment. The cellular phone 1 includes a control unit 51 that performs overall control. Other main components include a communication unit 52, an antenna 53, a signal processing unit 54, a voice input / output unit 55, an input unit 56, and a display unit 57. A storage unit 58 and a power source control unit 59.

  The communication unit 52 is for performing wireless communication with a base station of a mobile communication network (not shown) according to an instruction from the control unit 51. At the time of information reception, the antenna 53 receives a radio wave transmitted from the base station, converts it into an electrical signal, and this signal is input to the communication unit 52. The communication unit 52 down-converts the received electrical signal into a baseband signal and outputs it to the signal processing unit 54. On the other hand, when transmitting information, the communication unit 52 up-converts the transmission signal output from the signal processing unit 54 into a radio frequency signal, converts the electrical signal into a radio wave by the antenna 53, and radiates it to space.

  When a baseband signal is input from the communication unit 52, the signal processing unit 54 modulates the baseband signal and separates error-corrected data for each medium. For example, when a call voice is received, the voice data included in the received data is decoded and output to the voice input / output unit 55. For example, if the received data includes moving image data as in a videophone, the moving image data is also decoded and output to the display unit 57.

  Further, the signal processing unit 54 is based on the control from the control unit 51 and transmits a transmission signal based on voice data input from the voice input / output unit 55, transmission data such as e-mail data provided from the control unit 51, and the like. Can be generated and output to the communication unit 52.

  The voice input / output unit 55 includes a speaker and a microphone. The voice input / output unit 55 can convert voice input via the microphone into voice data by PCM encoding and output the voice data to the signal processing unit 54. Also, the audio data input from the signal processing unit 54 can be PCM decoded and amplified, and then output from the speaker.

  The input unit 56 receives an instruction from the user and outputs information representing the user's instruction to the control unit 51. Although FIG. 1 illustrates the key 12 as an input device using a key switch, the present invention is not limited to this, and an input device using a touch panel, for example, may be used.

  The display unit 57 is a display device using an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence), or the like, and displays images, characters, and the like according to application software executed by the control unit 51.

  The storage unit 58 stores application software executed by the control unit 51, user information of the mobile phone 1, a conversion dictionary 58a used for character conversion executed by the control unit 51, and the like. The conversion dictionary 58a will be described in detail later.

  The power supply control unit 59 measures the output voltage of a battery (not shown) and controls the voltage of electrical energy sent from the battery. Further, when the voltage of the battery drops below a certain value, the mobile phone 1 is made incapable of being turned on and protected from overdischarge. Further, the power control unit 59 outputs information indicating the battery voltage to the control unit 51. The control unit 51 can notify the user of the mobile phone 1 of the remaining amount of battery energy by displaying an icon representing the remaining amount of battery energy on the display unit 57 in accordance with the information indicating the voltage of the battery. .

  FIG. 3 is a configuration example of the conversion dictionary 58a. In the conversion dictionary 58a, headwords, readings of the headwords, parts of speech, categories, priorities, input prediction phrases, and the like are registered. This conversion dictionary 58a selects a headword having an input kana character as a reading (hereinafter referred to as kana-kanji conversion), and selects a headword having the input kana character at the beginning of the reading as a candidate. It is used for a function (hereinafter referred to as predictive conversion) and a function for selecting a candidate by predicting a word input next to a character whose input is confirmed (hereinafter referred to as phrase prediction).

  The priority of the conversion dictionary 58a is used to determine the order of selection when candidates are selected by predictive conversion. For example, in the conversion dictionary 58a as shown in FIG. 3, “morning” has the highest priority among “morning”, “Asakusa”, and “the day after tomorrow”. Therefore, when the prediction “Asa” is input and the prediction conversion candidate is displayed on the display 11, the prediction conversion candidate “morning” is the number of operations for the selection operation using the key 12 more than other prediction conversion candidates. Is displayed at a position where there is less. Since this priority can be learned so that the priority of candidates whose input has been confirmed in the past becomes high, the burden on the user can be increased by displaying the candidates that are likely to be input by the user at positions where they can be easily selected. Reduce.

  The input prediction phrase of the conversion dictionary 58a is used when candidates are selected by phrase prediction. For example, when the conversion dictionary 58a as shown in FIG. 3 is used, when the input character string “morning” is confirmed, “early” and “rice” that are used subsequently to “morning” are selected as phrase prediction candidates. The

  A process when the mobile phone 1 having the above-described configuration performs information search will be described with reference to FIGS. FIG. 4 is a flowchart showing the processing of the control unit 51 when information search is performed using the input character string. FIG. 5 is a flowchart showing processing of the control unit 51 when one of conversion candidates obtained by performing character conversion from an input character string is selected. FIG. 6 is a transition diagram of screens displayed on the display 11 when the mobile phone 1 searches for information.

  First, the control unit 51 receives an information retrieval application activation instruction from the user via the input unit 56, and activates the information retrieval application based on the instruction (S101). As a result, an information retrieval application screen as shown in FIG. When the control unit 51 detects that a character has been input using the character input key 12a (Yes in S102), the control unit 51 displays the input character (S103). Then, the conversion dictionary 58a is searched using the input characters as keys (S104). Note that the characters detected in step S102 may be kana characters, alphabets or numbers. Here, explanation is given assuming that the kana character “a” is input. When detecting that “a” is input, the control unit 51 selects headings having “a” at the head as readings of the conversion dictionary 58a in descending order of priority. As a result, conversion candidates such as “A”, “Aku”, and “Open” are selected. These conversion candidates are displayed on the display 11 in descending order of priority (S105).

  Further, the control unit 51 executes a search process using the conversion candidate with the highest priority among the conversion candidates selected in step S104 as a keyword (S106). Here, the search target is, for example, a Web page, a received mail, a telephone directory, a dictionary, a TV program guide, and the like. In the example shown in FIG. 6, options tabs such as a Web page, mail, a telephone directory, a dictionary, and a TV program guide are displayed as targets, and the Web page is selected as a search target. Note that the tab of the example shown in FIG. 6 includes a tab called “input prediction”. In this application, even if there is a mode that does not search for input characters but only performs character conversion. good. Further, FIG. 6 shows a case where there are Web pages, mails, telephone books, dictionaries, TV program guides, and the like as search targets, but these search targets may be freely set by the user. When the search target can be set by the user, any number of search targets may be set. For example, it is conceivable to add an incoming call history or schedule as a search target.

  In step S106, the control unit 51 searches the currently selected search target (Web in the example shown in FIG. 6) using the conversion candidate with the highest priority as a keyword. Then, control is performed so that the obtained search result is stored in the storage unit 58. In addition, among the obtained search results, search results for the number of items that can be displayed on the display 11 are displayed (S107). As a result, the display 11 is in a state as shown in FIG. That is, for the input character “A”, the input prediction results “A”, “Aku”, “Open”, “A”, “1”, “That”, “Ano” are displayed in the lower left column. Then, the Web search result for the candidate “A certain” having the highest priority among these candidates is displayed in the lower right.

  Following the search process using the conversion candidate with the highest priority, the control unit 51 searches the search target using the conversion candidate with the next highest priority as a keyword (S108). At this time, an operation by the user via the input unit 56 for selecting a conversion candidate with the next highest priority is not necessary. The search result is stored in the storage unit 58 without being displayed on the display 11 (S109). Thus, since the display content of the display 11 is not changed, the control unit 51 can perform a search process using a plurality of conversion candidates without the intention of the user. Further, the control unit 51 learns the conversion dictionary 58a using the search result (S110). Specifically, the number of search results when searching using conversion candidates is compared with a predetermined threshold. If the number of search results is greater than the threshold, the priority registered in the conversion dictionary 58a is increased. To control. This makes it possible to increase the priority of words that are frequently used in search targets such as the Web.

  Then, the control unit 51 determines whether or not search processing has been performed on all candidates obtained as conversion candidates (S111). The processing from S108 is repeated.

  When the next character is input after the already input character, the processing from step S103 is performed. FIG. 6C shows a display on the display 11 when the character “sa” is input after the character “a”. In the example of FIG. 6C, because the input character has changed from “A” to “Asa”, the conversion dictionary 58 a is searched for “Asa” and conversion candidates having readings starting from “Asa” are displayed on the display 11. It is displayed in the lower left. And the result of having searched search object (for example, Web) using the extracted conversion candidate is displayed on the lower right.

  FIG. 5 is a flowchart showing the processing of the control unit 51 when one conversion candidate is selected from the displayed conversion candidates. For example, when “Asakusa”, which is one conversion candidate, is selected from the conversion candidates displayed as shown in the lower left of FIG. 6C, “Asakusa” is already selected as the keyword in steps S108 and S109 of FIG. The search result as shown in FIG. 7 is stored in the storage unit 58. Therefore, the control unit 51 controls to display the search result stored in the storage unit 58 on the display 11 (S202), and learns the conversion dictionary 58a so that the priority of the selected conversion candidate becomes high (S202). S203). As described above, when one conversion candidate is selected from the conversion candidates displayed in step S201, since the conversion using the conversion candidate has already been completed, the search is performed from when the conversion candidate is selected. Compared with the case of starting, the time taken to display the search result can be shortened. In addition, since the conversion candidate designated as the search keyword is likely to be used later for character input to other applications, the control unit 51 uses the information of the selected conversion candidate to convert the conversion dictionary 58a. By performing this learning, the priority of the conversion candidate designated as the search keyword can be increased.

  The result of the search using the conversion candidate stored in the storage unit 58 as a keyword is stored until the information search application is terminated, and is erased from the storage unit 58 when the information search application is terminated. Alternatively, even if the information search application is terminated, it may not be deleted until a predetermined time (for example, one day) elapses. When the control unit 51 receives a character input via the input unit 56, the control unit 51 starts a search using the prediction candidate, and thus performs a search using a prediction candidate predicted from an input character string of one character as a keyword. Results are displayed more frequently. Therefore, even if the information search application is terminated, the search processing can be omitted by storing the search results until a predetermined time has elapsed.

  As described above, when a candidate for conversion that is the result of predictive conversion using the input characters is searched and stored, the conversion candidate is specified and displayed when the search result is displayed. By displaying the stored search results, the information search results can be displayed quickly.

  In addition, it is not limited to the said embodiment, You may change suitably in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the Web search is selected as the search target and the Web search is performed using the input character conversion candidate. However, even if the Web search is selected, other search is performed. A search may be executed for the search target. For example, when the web search is selected, not only the web search using the input character conversion candidates but also the search of the received mail and the phone book are performed, and the search result is stored in the storage unit 58. May be. In this way, by using the input character conversion candidates, not only one search target but also a plurality of search targets are searched, so that even when the search target is switched, the search result is quickly displayed. Can be displayed.
