Description

  The present invention relates to an electronic device that performs a character conversion operation according to a character input by a user, and a character conversion method.

  In recent years, multimedia use of electronic devices has been accelerated. For example, television receivers are equipped not only with a function for simply watching television broadcasts but also with a variety of functions such as a web browsing function connected to the Internet and a mail transmission / reception function. With the installation of these functions, opportunities for inputting characters into electronic devices are increasing. For example, Patent Documents 1 and 2 disclose a mobile phone capable of multi-job such as a function of viewing a television broadcast and a mail function.

  Therefore, the electronic device is equipped with an input prediction function for presenting conversion candidates for characters input by the user. In this input prediction function, conversion candidates corresponding to the input characters are searched from a conversion database stored in advance in a storage device and presented to the user. For example, when the character “A” is input by the user, a phrase (character string) beginning with “A” such as “Ashita” and “Tomorrow” is presented as a conversion candidate.

  The input prediction function is usually not linked to other functions of the electrical equipment. For example, in a television receiver, even if a user inputs characters while viewing a television broadcast, the input prediction function is not affected by the content of the television broadcast being viewed. Therefore, the input prediction function presents the same conversion candidates as when the television broadcast is not viewed.

  However, the user's character input is often closely related to the function used by the user. For example, a user's character input during viewing of a television broadcast is often intended for a phrase relating to the content of the television broadcast being viewed. However, even if characters are input during viewing of the television broadcast, the displayed conversion candidates are not linked to the contents of the currently viewed television broadcast, and general conversion candidates are displayed.

  In such a case, it is necessary to find an appropriate word from a plurality of conversion candidates presented by the input prediction function without being linked to the content of the television broadcast being viewed. Therefore, the purpose of the input prediction function of reducing the burden of user character input is impaired. In particular, while watching a television broadcast, it is desirable that the user can quickly input characters at a specific moment of the program, but it is difficult to sufficiently cope with such a situation with a normal input prediction function.

  On the other hand, in order to quickly cope with such a situation, there is a method in which words or phrases are registered at any time in the character conversion database from the program information of the television broadcast being viewed. For example, in Patent Document 3, a word extracted from a program name and program information is registered in dictionary data. Further, in Patent Document 4, a predetermined character string is extracted from content metadata, and if the extracted character string is an unregistered word, the character string is registered in the dictionary data. However, even after the end of the viewing of the television broadcast, the character conversion into the character string registered by the user is not necessarily intended. Therefore, rather than registering a character string in the dictionary data, it is desirable to comprehensively cope with the situation by presenting a plurality of conversion candidates suitable for the situation and widening the user's choice of character input.

  The present invention has been made in view of such a situation, and when performing a character conversion operation during reproduction of content, an electronic device that can preferentially display character string conversion candidates according to the content, An object of the present invention is to provide a character conversion method.

  In order to achieve the above object, an electronic device according to the present invention includes an input unit that receives a character input from a user, a database storage unit that stores a plurality of field-specific databases in which character strings of the same genre are accumulated for each different genre, and , Priority information for setting the priority of the field database used for the character conversion operation of the character input, a storage unit for storing the content, a playback control unit for controlling playback of the content, and playing A metadata analysis unit that extracts the genre of the content from the metadata of the content, a collation unit that collates the extracted genre and the genre of the field database, and the priority order according to a collation result of the collation unit An editing section that changes the setting of the character string, and conversion candidates of character strings according to the character input based on the order of the priorities. A conversion unit for selecting from the database, characterized in that it comprises a display unit for displaying the conversion candidates.

  In the above configuration, when the reproduction of the content ends, the editing unit may return the priority set in the priority information to a preset priority.

  Further, in the above configuration, a field-specific database used for the character conversion operation is further registered in the priority information, and the collation unit is registered in the extracted genre and the priority information. The conversion unit may collate with the genre of the field database, and the conversion unit may select the conversion candidate from the field database registered in the priority information.

  Moreover, the said structure WHEREIN: The said edit part may change the said database according to the field registered into the said priority information according to the collation result of the said collation part.

  In order to achieve the above object, a character conversion method of the present invention includes a step of receiving a user's character input, a step of reproducing content stored in a storage unit, and metadata of the content being reproduced. Depending on the collation result in the step of extracting the genre of the content, the step of collating the extracted genre and the genre of the field-specific database stored in the database storage unit for each different genre, and the collating step A step of changing the priority setting of the field-specific database in which character strings of the same genre are accumulated, and based on the order of the priority, from the field-specific database used for the character conversion operation of the character input, Selecting a conversion candidate for a character string in accordance with the character input; and a step for displaying the conversion candidate. Tsu and up, characterized in that it comprises a.

Embodiments of the present invention will be described below with reference to the drawings.
<First Embodiment>

  FIG. 1 is a configuration diagram of a tablet computer according to an embodiment of the present invention. The tablet computer 1 is an example of an electronic device equipped with an input prediction function for a user's character input. As shown in FIG. 1, the tablet computer 1 includes a communication unit 11, an antenna 11a, a storage unit 20, a database storage unit 30, a touch panel 40, an MPU (micro processing unit) 50, and a speaker 60. Prepare.

  The communication unit 11 is a communication interface that performs wireless communication via the antenna 11a. As this wireless communication, for example, Bluetooth (registered trademark), FM communication, wireless LAN, mobile communication, or the like can be used. The wireless communication performed by the communication unit 11 realizes various content communication functions (for example, reception of digital television broadcasts, music distribution, etc.), mail functions, Internet functions, and the like.

  The storage unit 20 and the database storage unit 30 are nonvolatile recording media. Note that the storage unit 20 and the database storage unit 30 may be the same storage medium, or may be individually provided recording media. The storage unit 20 stores programs and control information used by each component of the tablet computer 1. In addition, the storage unit 20 stores content that can be reproduced by the tablet computer 1 and priority information. As content, for example, television broadcast (digital television broadcast, satellite broadcast, etc.) received via the communication unit 11, video content such as movies and videos, audio content such as music, and tablet computer 1 Examples of application programs that can be used. In the priority order information, a field-specific database 31 (described later) used for a character conversion operation in accordance with a user's character input during content reproduction and the priority order of the field-specific database 31 are set.

  The database storage unit 30 stores a plurality of field-specific databases 31 for different genres. In each field-specific database 31, phrases (character strings) of the same genre are accumulated. For example, the first field-specific database 31a is a general database in which words and phrases classified into “general” are accumulated, and words that are not biased to a specific genre are accumulated. In the second field database 31b, words and phrases whose genre is classified as "cooking" are stored. In the third field-specific database 31c, words and phrases whose genre is classified as “soccer” are stored. In the present embodiment, as an example of a plurality of field databases 31, database fields 31 a to 31 c (see FIG. 3 described later) of “general”, “cooking”, and “soccer” are shown. In addition, it goes without saying that the database storage unit 30 includes field-specific databases 31 of various genres.

  The touch panel 40 is an example of a display input unit that receives a user input by a user's touch operation. For example, when a user's finger or a touch pen touches the display screen, the touch panel 40 receives a user input indicated by the touch operation. The touch panel 40 includes a liquid crystal display 41 and a software keyboard 42. The liquid crystal display 41 is an example of a display unit, and displays a content reproduction screen, a character string predictive conversion candidate in a character conversion operation, and the like (see FIG. 4 described later). The software keyboard 42 is an example of an input unit that accepts user character input, and is a virtual input interface that can be displayed on the liquid crystal display 41. The user can perform user input including character input by performing operation input on the software keyboard 42.

  The MPU 50 is a control unit that controls each component included in the tablet computer 1 using a program and control information stored in the storage unit 20. The MPU 50 includes a metadata analysis unit 51, a collation unit 52, an editing unit 53, a conversion unit 54, and a reproduction control unit 55. The metadata analysis unit 51 reads the genre of the content and its contents from the metadata of the content being reproduced. Further, the metadata analysis unit 51 analyzes the content by using a technique such as syntax analysis and morphological analysis, and extracts the genre of the content being reproduced from the analysis result.

  The collation unit 52 collates the genre extracted by the metadata analysis unit 51 with each genre in the field-specific database 31 registered in the priority order information. Then, the collation unit 52 can determine whether or not the field-specific database 31 that matches the extracted genre is registered in the priority information. Moreover, the collation part 52 can also determine whether the field-specific database 31 of the genre that does not match the extracted genre is registered in the priority information.

  The editing unit 53 edits the priority order information according to the collation result of the collation unit 52. For example, the editing unit 53 changes the priority order setting in the field-specific database 31 registered in the priority order information. Specifically, the editing unit 53 sets the priority order of the field-specific database 31 determined by the collation unit 52 to match the genre among all the field-specific databases 31 registered in the priority order information. It is set higher than the separate database 31 (see FIG. 3 described later).

  Note that the editing unit 53 maintains the setting of the priority information that is edited during the reproduction of the content while the content is being reproduced. On the other hand, when the reproduction of the content ends, the editing unit 53 returns the priority order information to the preset initial state. Therefore, the field-specific database 31 set in the priority information and the priority order thereof are returned to the field-specific database 31 in the initial state and the priority order set in advance. In this way, it is possible to preferentially display a character string predictive conversion candidate corresponding to the content being reproduced without being affected by the content reproduction history.

  In the character conversion operation during the reproduction of the content, the conversion unit 54 selects a character string predictive conversion candidate from each field-specific database 31 according to the user's character input based on the order of priority indicated by the priority information. In addition, in the character conversion operation in a state where the content is not reproduced, the conversion unit 54 selects a predictive conversion candidate for a character string according to the user's character input from the first field-specific database 31 whose genre is “general”. To do. Moreover, the conversion part 54 can convert a user's character input into the character string of the prediction conversion candidate selected by user input based on a user input.

  The reproduction control unit 55 performs content reproduction control, touch panel 40 display control, speaker 60 audio output control, and the like. Further, the reproduction control unit 55 displays the predicted conversion candidates for the character string selected by the conversion unit 54 at a predetermined display position on the liquid crystal display 41 in the order corresponding to the priority of the field-specific database 31 indicated by the priority information. (See FIG. 4 described later). Further, the reproduction control unit 55 causes the liquid crystal display 41 to display the character string converted by the conversion unit 54 instead of the user character input.

  The speaker 60 is an example of an audio output unit, and performs audio output of content being reproduced, for example.

  Next, an operation in which the tablet computer 1 performs character conversion during content reproduction will be described. FIG. 2 is a flowchart showing a flow of character conversion operation during reproduction of content in the first embodiment. Note that FIG. 2 will be described by taking a digital television broadcast received by the communication unit 11 as an example of content to be reproduced.

  First, it is determined by the reproduction control unit 55 whether or not viewing of the digital television broadcast is started (step S101). When it is determined that viewing has started (YES in step S101), program information (an example of metadata) such as EPG (Electric Program Guide) received together with the digital television broadcast by the metadata analysis unit 51. ) Is read. Further, the genre of the digital television broadcast being viewed is extracted from the analysis result of the program information by the metadata analysis unit 51 (step S102).

  Next, the collation unit 52 collates the extracted genre with the genre in the field-specific database 31 registered in the priority information (step S103). In accordance with the collation result, the priority indicated by the priority information is changed by the editing unit 53 (step S104). FIG. 3 is a conceptual diagram showing an example of changing the priority order of the field-specific database 31. For example, when “soccer” is extracted as the genre of digital television broadcasting by the metadata analysis unit 51, as shown in FIG. 3, the priority of the third field database 31c whose genre is “soccer” is other fields. It is set to be higher than the separate database 31 (for example, the “general” and “dishes” field-specific databases 31a and 31b).

  Next, the reproduction control unit 55 determines whether or not the user's character input is accepted on the touch panel 40 (step S105). When it is determined that character input is not accepted (NO in step S105), the process of step S109 described later is performed. On the other hand, when it is determined that the character input has been accepted (YES in step S105), the conversion unit 54, based on the priority order indicated by the priority order information, from the field-specific database 31 registered in the priority order information, A predictive conversion candidate for a character string corresponding to a character input is selected. Further, the reproduction control unit 55 displays the predicted conversion candidates for the selected character string on the liquid crystal display 41 in the order of priority indicated by the priority order information (step S106).

  FIG. 4 is a diagram illustrating an example of a display screen for predictive conversion candidates for character strings. In FIG. 4, a content playback screen 411, a character conversion screen 412, and a software keyboard 42 are displayed on the display screen 410 of the liquid crystal display 41. For example, when watching a soccer relay program, the priority of the priority information is set so that the third field database 31c whose genre is “soccer” is the highest (see FIG. 3). At this time, when the character “Ofu” is input using the software keyboard 42, a predictive conversion candidate for the character string is selected from the third field database 31c of the genre “soccer” having the highest priority. After that, according to the order of priority indicated by the priority information, the character string prediction conversion candidate from the first field database 31a of the “general” genre and the character string from the second field database 31b of the “food” genre Candidate predictive conversions are selected. The character conversion screen 412 displays prediction conversion candidates selected from the third field database 31c of the category “soccer” as prediction conversion candidates for character input, and each of “general” and “cooking”. Predictive conversion candidates (not shown) selected from the field-specific databases 31a and 31b are sequentially displayed. Note that selection and display of prediction conversion candidates are executed for all the field-specific databases 31 registered in the priority order information. Further, the number of prediction conversion candidates that can be displayed on the character conversion screen 412 is limited. Therefore, on the actual character conversion screen 412, a predetermined number of predictive conversion candidates are displayed in descending order of priority. Note that the predicted conversion candidates to be displayed are sequentially switched according to user input.

  Next, the user can select a desired character string from each prediction conversion candidate displayed on the liquid crystal display 41. Here, first, whether or not a user input for selecting any one of the prediction conversion candidates displayed on the liquid crystal display 41 by the reproduction control unit 55 has been received by the touch panel 40 (or the software keyboard 42). Is determined (step S107). If it is determined that no user input has been received (NO in step S107), the process returns to step S107, and waits until a user input is received. Note that, in the standby state, when viewing of the digital television broadcast is completed, a process of step S110 described later may be executed.

  On the other hand, when it is determined that user input has been received (YES in step S107), the conversion unit 54 converts the character input received in step S105 into a character string of a predictive conversion candidate selected by the user input. . Then, the reproduction control unit 55 displays the converted character string on the liquid crystal display 41 instead of the accepted character input (step S108).

  Next, the playback control unit 55 determines whether or not the viewing of the digital television broadcast has been completed (step S109). If it is determined that the process has not ended (NO in step S109), the process returns to step S102. In this way, even if the program content (and its genre) changes during the viewing of digital television broadcast, the priority order of the priority information can be changed according to the genre.

  On the other hand, when it is determined that the processing has been completed (YES in step S109), the priority order information is initialized (reset) by the editing unit 53 (step S110). By this initialization, the field-specific database 31 registered in the priority order information and its priority order are returned to the preset initial settings. Then, the character conversion operation during viewing of the digital television broadcast ends, and the character conversion operation is switched to the character conversion operation based on the first field-specific database 31a whose genre is “general”.

  In the above flowchart, the viewing of digital television broadcasting has been described as an example of content playback, but the scope of application of the present invention is not limited to this example. The content may be, for example, audio content such as music, video content such as movies and videos, and application programs that can be used on the tablet computer 1.

  As described above, in the first embodiment, the genre of the content (digital television broadcast) being reproduced is extracted from the metadata (program information). The extracted genre is collated with the genre in the field-specific database 31. The priority setting of the field-specific database 31 used for the character conversion operation is changed according to the collation result. Therefore, the prediction conversion candidate of the character string according to a user's character input is selected and displayed from the field database 31 based on the changed order of priority. Therefore, when a character conversion operation is performed during the reproduction of content, a predictive conversion candidate for a character string corresponding to the content can be preferentially displayed.

  That is, it is possible to display a predicted conversion candidate assumed to be converted by the user at a position closer to the head. Therefore, the user can easily find a desired prediction conversion candidate from the displayed plurality of prediction conversion candidates. Further, since the user does not need to perform an operation input for instructing an operation for finding a desired prediction conversion candidate (for example, scrolling or switching the display screen), the operation procedure for performing the character conversion operation is reduced. You can also.

  In this way, if the prediction conversion candidates for the character string corresponding to the user's situation are displayed, the selection range of the user at the time of character input is widened, and the character conversion operation can be performed more smoothly. In this embodiment, instead of pinpointing prediction conversion candidates for a specific character string to the user, a plurality of prediction conversion candidates predicted to be input by the user during playback of the content are generally referred to as content genres. Therefore, it is possible to further improve the possibility that the user can immediately find the prediction conversion candidate that the user wants.

Further, a field-specific database 31 used for the character conversion operation is further registered in the priority information. The collation unit 52 collates the extracted genre with the genre of the field-specific database 31 registered in the priority order information. The conversion unit 54 selects a character string predictive conversion candidate from the field-specific database 31 registered in the priority information. Therefore, using the field-specific database 31 registered in the priority information, it is possible to collate genres and select prediction conversion candidates. Accordingly, it is possible to more quickly select and display a predictive conversion candidate corresponding to the content being reproduced.
Second Embodiment

  Next, a second embodiment will be described. In the second embodiment, after it is determined that the first content being played has ended, it is determined whether or not the second content different from the first content is played. When it is determined that the second content is to be reproduced, the priority information is edited based on the genre extracted from the metadata of the second content. The rest is the same as in the first embodiment. In the following description, a configuration different from the first embodiment will be mainly described. Moreover, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 5 is a flowchart showing a flow of character conversion operation during reproduction of content in the second embodiment. Note that FIG. 5 illustrates digital television broadcasting as an example of the first content, and music data distributed from the Internet as an example of the second content.

  In the second embodiment, as shown in FIG. 5, when it is determined that the viewing of the digital television broadcast (first content) has ended (YES in step S109), the playback control unit 55 performs the digital television broadcast. It is determined whether or not the second content different from the broadcast (first content) is reproduced (step S221). If it is determined that the second content is not reproduced (NO in step 221), the process of step S110 is performed.

  On the other hand, for example, when it is determined that the music data (second content) is reproduced (YES in step 221), the process returns to step S102. In step S102, the metadata analysis unit 51 reads the music data property information (an example of metadata). Further, the metadata analysis unit 51 analyzes the property information and extracts the genre of the music data from the result. At this time, for example, “music” may be extracted as the genre, or the type of music such as the artist name, “classic” or “J-POP” may be extracted.

And the process after step S103 is performed using the extracted genre. If it is determined in step S109 that the music data has been played back (YES in step S109), and it is determined that another content is not played back (NO in step S221), the priority information is set in S110. It is initialized. Thereafter, the character conversion operation during the reproduction of the content ends, and the character conversion operation is switched to the character conversion operation based on the first field database 31a whose genre is “general”.
<Third Embodiment>

  Next, a third embodiment will be described. In the third embodiment, the editing unit 53 further changes the setting of the field-specific database 31 registered in the priority order information. Specifically, if the field-specific database 31 determined by the collation unit 52 to match the genre of the content being played back is not registered in the priority information, the editing unit 53 sets the field-specific database 31 as a priority. Register for information. In addition, when the field-specific database 31 determined by the collation unit 52 as not matching the genre is registered in the priority information, the editing unit 53 deletes the registration of the field-specific database 31 from the priority information. The rest is the same as in the first embodiment. In the following description, a configuration different from the first embodiment will be mainly described. Moreover, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 6 is a flowchart showing a flow of character conversion operation during reproduction of content in the third embodiment. In FIG. 6, a digital television broadcast received by the communication unit 11 will be described as an example of content to be reproduced.

  As shown in FIG. 6, after the genre of the television broadcast being viewed is extracted in step 102, the collation unit 52 registers the field-specific database 31 of the genre that matches the extracted genre in the priority information. It is determined whether or not (step S331). If it is determined that it is registered in the priority order information (YES in step S331), the process of step S333 described later is executed.

  On the other hand, when it is determined that it is not registered (NO in step S331), the editing unit 53 registers the field database 31 of the extracted genre in the priority information (step S332). FIG. 7 is a conceptual diagram showing an example of additional registration in the field database. For example, when “soccer” is extracted as the genre of the digital television broadcast being viewed, it is determined whether or not the third field database 31c of the genre that matches “soccer” is registered in the priority information. . If it is determined that it is not registered in the priority information, the third field database 31c of “soccer” is registered in the priority information as shown in FIG.

  Next, the collation unit 52 determines whether or not the field-specific database 31 of the genre that does not match the extracted genre is registered in the priority order information (step S333). If it is determined that it is not registered in the priority information (NO in step S333), the process of step S335 described later is executed.

  On the other hand, when it is determined that it is registered (YES in Step S333), the editing unit 53 deletes the registration of the discriminating category database 31 from the priority order information (Step S334). FIG. 8 is a conceptual diagram showing an example of deletion of registration in the field-specific database. For example, when the first to third field databases 31 a to 31 c of “general”, “cooking”, and “soccer” are registered in the priority order information, as shown in FIG. The field database 31b is deregistered from the priority information. In the example of FIG. 8, the registration of the first field database 31a whose genre is “general” is not deleted, but the registration of the first field database 31a may be deleted in step S334.

  Next, the priority information is edited by the editing unit 53, and the priority of the genre field database 31 extracted in step S102 is higher than the other field databases 31 registered in the priority information. (Step S335).

  Thus, in the third embodiment, the editing unit 53 changes the field-specific database 31 registered in the priority order information according to the collation result of the collation unit 52. Therefore, the registration of the field-specific database 31 used for the character conversion operation can be changed according to the genre of the content (digital television broadcast) being reproduced. Therefore, it is possible to more smoothly select and display a predictive conversion candidate of a character string that the user wants to input during content reproduction.

  Note that, in the third embodiment, similarly to the second embodiment, when it is determined that the second content different from the first content that has been reproduced is reproduced, the genre extracted from the metadata of the second content The priority order information may be further edited based on the above.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each component and combination of processes, and are within the scope of the present invention.

  For example, in the above-described embodiment, a predictive conversion operation is performed in which a character input conversion candidate is searched by partial match (for example, forward match, backward match, etc.) by the input prediction function, but the present invention is applied to this example. It is not limited. A normal conversion operation may be performed in which character input conversion candidates are searched from the field-specific database 31 with a perfect match.

  Further, in the above-described embodiment, the metadata analysis unit 51, the collation unit 52, the editing unit 53, the conversion unit 54, and the reproduction control unit 55 are realized as functional units of the MPU 50. It is not limited to examples. These may be realized by independent control units, or at least part of them may be realized by independent control units. Furthermore, these may be realized by a program stored in the storage unit 20, or may be realized by a device or a physical component (for example, an electronic circuit).

  Moreover, in the above-mentioned embodiment, although the tablet computer 1 is provided with the touch panel 40, the application range of this invention is not limited to this example. A display unit such as the liquid crystal display 41 and an input device or a physical input unit (for example, a keyboard, a keypad, etc.) may be provided separately.

  In the above-described embodiment, an example in which one genre is extracted from the metadata of the content being reproduced has been described, but the scope of application of the present invention is not limited to this example. A plurality of genres may be extracted. Furthermore, at least one of the field-specific database 31 registered in the priority order information and the setting of the priority order may be changed based on the result of collating the genre with the genre of the field-specific database 31.

  The present invention is applicable to electronic devices such as a mobile phone, a PHS phone, a PDA device, a tablet computer, a personal computer, and a television receiver.
