Description

  The present invention relates to a character code selection device for manually setting a character code used for describing character string data.

  2. Description of the Related Art Conventionally, there is known an automatic character code determination system that automatically determines a character code for input data, converts the input data into a character string using the determined character code, and outputs the character string (for example, (See Patent Document 1). In this character code automatic discrimination system, after binary values are converted into character strings using multiple character codes for input data, the character strings converted with each character code are statistically analyzed, and further based on the analysis results By assigning a statistical evaluation value to each character code, the type of character code used to describe the input data is determined.

JP 2010-176237 A (page 5-10, FIG. 1-7)

  By the way, it is possible to automatically determine the character code describing the input data by using the system disclosed in the above-mentioned Patent Document 1, but in general, when automatic determination is impossible or erroneously determined, The character code is specified manually. For example, when a character code is specified manually by a user in a state where a screen on which an erroneous character string (character string of unknown meaning) is displayed using the automatically determined character code is displayed, The erroneous character string being displayed is changed to a character string using the newly designated character code. When a correct character string is displayed by this change, conversion processing using this character code is performed thereafter. On the other hand, if an incorrect character string is displayed even after the change, the user again designates the character code by manual operation, and this operation is repeated until the display content is correct. As described above, conventionally, the specification of the character code by manual operation, the conversion of the character string using this character code, and the display of the character string after the conversion are repeated, and the number of operations increases and the operation is complicated. There was a problem that there was bad operability.

  The present invention was created in view of the above points, and its purpose is to reduce the number of operations when specifying a desired character code by manual operation, simplify the operation, and improve the operability. It is to provide a character code selection device.

  In order to solve the above-described problem, a character code selection device according to the present invention includes a character code name as a selection candidate and a character string obtained by converting a part of input data using the character code. A selection screen creation means for creating a character code selection screen including a set with a preview area having a selection area, a selection screen display means for displaying a character code selection screen created by the selection screen creation means, and accepting a user's operation An operation means and a character code selection means for selecting a character code included in the displayed character code selection screen in accordance with a user instruction using the operation means.

  The character code selection screen for selecting the character code contains the character string that results from the conversion using each character code, so the character code before actually selecting the character code and converting the input data It is possible to know whether or not the selection is appropriate, the number of operations when the character code is manually specified can be reduced, and the operation can be simplified and the operability can be improved.

  Also, before the character code is selected by the character code selection means, the character string conversion means for converting the input data into a character string using any of the character codes, and the character string conversion means And a character string display means for displaying the character string after being displayed, and when the character string is displayed by the character string display means, the user proceeds to the character code selection operation using the operation means. It is desirable that the character code selection screen is displayed when an instruction is issued. As a result, it is only necessary to specify the character code by manual operation only when an error in the character code is found based on the display content at that time. The number of operations can be reduced, the operation can be simplified, and the operability can be improved.

  Further, the selection screen creation means described above uses input data corresponding to the character string displayed on the character string display means immediately before displaying the character code selection screen as a part of the input data corresponding to the preview area. Is desirable. Since a preview area can be created using input data when an error in display content is found, it is possible to reliably know whether or not correct conversion is performed as a result of using each character code.

  Also, a preview target range indicating a range of character code values that can be displayed in the preview area and a preview target exclusion range indicating a range of character code values excluded from the display target in the preview area are set in advance. The selection screen creation means is input data corresponding to the character string displayed on the character string display means immediately before displaying the character code selection screen, and the input data included in the preview target range is displayed in the preview area. It is desirable to use as a part of input data corresponding to. Specifically, it is desirable that the above-described preview target exclusion range includes numbers and character code values corresponding to alphabets. Alternatively, in the above-described preview target exclusion range, in addition to the character code values corresponding to numerals and alphabets, it is confirmed that the same symbol corresponds to the common value of a plurality of character codes in advance. It is desirable that the value of the character code corresponding to the symbol is included. As a result, it is possible to extract from the input data being displayed that the display contents of the preview area differ corresponding to each character code, so that the correct conversion is performed as a result of using each character code. You can know more reliably whether or not.

  Further, the display of the character string by the character string display means described above is performed while the display content is scrolled according to the instruction of the user using the operation means, and the selection screen creation means is used using the operation means. When the shift to the character code selection operation is instructed according to the user's instruction, the input data corresponding to the character string added last as the character string to be displayed by the character string display means is associated with the preview area. It is desirable to use it as input data for a part. As a result, it is possible to display the result of converting each character code on the input data in which a new conversion error has occurred by scrolling the display content in the preview area, so that a desired character code can be easily found. be able to.

  In addition, after the character code is selected by the character code selection means described above, the character string conversion means for converting the input data into a character string using the selected character code, and the character string conversion means It is desirable to further include character string display means for displaying the character string after being processed. Thus, after an appropriate character code is designated with a small number of operations, the input data is correctly converted again using this character code, and a correct character string corresponding to the input data can be displayed.

  In addition, it is desirable that the character code selection screen is displayed when the user instructs to shift to the character code selection operation using the operation means described above. As a result, manual setting of the character code can be performed only when necessary and only when the user desires.

  In addition, the character code selection screen described above includes a plurality of sets of character code names and preview areas, and the character code selection means can select the plurality of character codes in response to a user instruction using the operation means. It is desirable to select a character code with the correct content of the converted character string from the set. This makes it possible to compare and verify whether conversion is performed correctly for each of the plurality of character codes before actually specifying the character code. The number of operations when selecting a code can be greatly reduced.

  Further, the character code selection screen described above includes one set of the name of the character code and the preview area, and the selection screen creation means can select different characters according to the user's instruction using the operation means. The character code selection screen corresponding to the code is created one after another, and the character code selection means, according to the instruction of the user using the operation means, the contents of the converted character string included in any of the character code selection screens It is desirable to select the correct character code. As a result, even when selecting a character code on a device with a small display area, it is possible to check the correctness of the converted character string simply by displaying the character code as a selection candidate, and finally an appropriate character code. It is possible to greatly reduce the number of operations until selection is made.

  Further, the selection screen creation means described above creates a plurality of character code selection screens that are switched and displayed in a predetermined order, and the character codes corresponding to the languages with higher priority are included in the character code selection screen with the earlier display order. It is desirable that Specifically, it is desirable that the above-described language with a high priority is a language used set in a device to which input data is input. Alternatively, it is desirable that the above-described language with a high priority is the language that is most likely to be used at the place of use of the device to which input data is input. Alternatively, it is desirable that the above-described language with a high priority is a language corresponding to a character code that has been selected by the character code selection unit in the past. As a result, the possibility of selecting a desired character code when the display order is early can be increased, and the number of operations until then can be reduced.

  Further, the input data described above is phone book data stored in a memory provided in the mobile phone, and the content of the phone book data sent from the mobile phone is provided in the in-vehicle device when displayed on the in-vehicle device. It is desirable to manually select the character code to be used by the selection screen creation means, selection screen display means, operation means, and character code selection means. As a result, it is possible to simplify the operation until the contents that are not correctly displayed due to garbled characters are correctly displayed when the mobile phone manufactured and sold by each company is connected and the phone book data is read and displayed.

In addition, when the content of the phone book data displayed on the display unit 66 is not correct (when the character is garbled because the wrong character code is used), the control unit 68 sets the character code according to the user's instruction. Perform the manual setting process.

  Next, the detailed configuration of the control unit 68 will be described. FIG. 2 is a diagram showing a detailed configuration of the control unit 68, and shows a configuration mainly necessary for manual setting of the character code. As shown in FIG. 2, the control unit 68 includes a telephone directory data acquisition unit 70, a character code determination unit 74, a conversion processing unit 76, a telephone directory display processing unit 78, a selection screen creation unit 80, a selection screen display processing unit 82, A character code selection unit 84 is provided.

  The telephone directory data acquisition unit 70 acquires telephone directory data stored in the telephone directory memory 26 in the cellular phone 10 when the cellular phone 10 is connected. The acquired phone book data is stored in the phone book storage unit 62.

  The character code discriminating unit 74 discriminates a character code describing the phone book data. For example, when the acquired phone book data includes identification information for specifying a character code, the character code describing the phone book data is determined by extracting the identification information. Alternatively, the character code may be automatically determined using a method described in Patent Document 1 (Japanese Patent Laid-Open No. 2010-176237).

  The conversion processing unit 76 uses the character code determined by the character code determining unit 74 (or the character code selected by manual setting described later) for the phone book data stored in the phone book storage unit 62. Perform encoding and convert to character string.

  The phone book display processing unit 78 performs processing for displaying the phone book including the character string converted by the conversion processing unit 76 on the display unit 66.

  The selection screen creation unit 80 creates a character code selection screen when the user instructs to shift to a manual character code selection operation using the operation unit 60. This character code selection screen includes a set of a character code name as a selection candidate and a preview area having a character string after converting a part of the phone book data using this character code. It is. A specific example of the character code selection screen will be described later.

  The selection screen display processing unit 82 displays the character code selection screen created by the selection screen creation unit 80 on the display unit 66.

  The character code selection unit 84 selects one of the character codes included in the displayed character code selection screen in accordance with a user instruction using the operation unit 60.

  The selection screen creation unit 80 described above is a selection screen creation unit, the selection screen display processing unit 82 and the display unit 66 are selection screen display units, the operation unit 60 is an operation unit, and the character code selection unit 84 is a character code selection unit. The conversion processing unit 76 corresponds to the character string conversion unit, and the telephone directory display processing unit 78 and the display unit 66 correspond to the character string display unit.

  The hands-free telephone system of the present embodiment has such a configuration, and next, operations related to character code setting will be described. FIG. 3 is a flowchart showing an operation procedure of the control unit 68 in the hands-free telephone device 50 related to the character code setting.

  The phone book data income unit 70 determines whether or not the mobile phone 10 is connected (whether or not the phone book data can be acquired through Bluetooth communication) (step 100). Make a decision and repeat this decision. If the mobile phone 10 is connected, an affirmative determination is made in step 100, and the phone book data acquisition unit 70 acquires phone book data from the mobile phone 10 (step 102). The acquired phone book data is stored in the phone book storage unit 62.

  Next, the character code discriminating unit 74 discriminates the character code used when describing this data based on the phone book data stored in the phone book storage unit 62 (step 104). The conversion processing unit 76 reads the phone book data stored in the phone book storage unit 62, converts it into a character string using the determined character code (step 106), and the phone book display processing unit 78 The phone book including the converted character string is displayed on the display unit 66 (step 108). Further, the phone book display processing unit 78 determines whether or not a page change is instructed for the currently displayed phone book (step 110). The display operation after step 108 is repeated for the telephone book of the page. If no change instruction has been given, a negative determination is made in the determination of step 110, and the selection screen creation unit 80 determines whether or not a change of the character code has been instructed (step 112). If the change of the character code is not instructed, a negative determination is made, and the process returns to step 110 to repeat the operation after the presence / absence determination of the page change instruction. Note that the change instruction in steps 110 and 112 is performed by the user using the operation unit 60.

  FIG. 4 is a diagram showing a specific example of the phone book screen. 4A shows a display example of the first page of the telephone book, FIG. 4B shows a display example of the second page of the telephone book, and FIG. 4C shows a telephone excluding the telephone book data. A display example of the book is shown.

  As shown in FIG. 4C, the phone book screen includes a “phone book” indicating that the phone book screen is displayed, “1, 2, 3, 4” that is a serial number of the phone book list, and a phone book. “Name / famous place” and “phone number” as list item names, page change buttons 100 and 102 for instructing to change the display page of the phone book, and scroll buttons 104 for instructing to scroll the contents of the phone book list, 106 and a character code change button 110 for instructing to change the character code used for conversion at that time. Note that the example shown in FIG. 4C corresponds to the first page of the phone book shown in FIG. 4A and cannot be changed or scrolled to the previous page. The page change button 102 and the scroll button 106 used for instructing are hidden or inconspicuously displayed.

  As shown in FIG. 4A, the first page of the phone book screen has a specific name / name and phone number for the first four phone book data in the content shown in FIG. 4C. Data is added. In this state, for example, when the user points the page change button 104 with a finger or the like, the display is switched to the phonebook screen of the second page shown in FIG. This phonebook screen on the second page is the same as the contents shown in Fig. 4C (however, the serial number in the phonebook list has been changed), and the name / name and phone number for the next four phonebook data. The specific data is added.

  In this way, each page of the phone book screen is displayed. The user can make a call to the displayed telephone number by selecting the other party from the displayed telephone directory list while viewing the telephone directory screen. When the call ends, the process returns to step 108 and the phone book screen is displayed.

  When the user is instructed to change the character code by operating the operation unit 60, an affirmative determination is made in the determination of step 112. Next, the selection screen creation unit 80 creates a character code selection screen, and the selection screen display processing unit 82 displays the created character code selection screen on the display unit 66 (step 114).

  FIG. 5 is a diagram showing a specific example of the character code selection screen. As shown in FIG. 5, the character code selection screen includes a “character code selection screen” indicating a character code selection screen, and “ASCII” and “Latin” which are names of five types of character codes to be selected. -1 "," Unicode UTF-8 "," Unicode UTF-16LE "," Unicode UTF-16BE ", and after converting some of the phonebook data using these five types of character codes Preview areas 200 to 208 including character strings, page change buttons 210 and 212 for instructing to change the display page of the character code selection screen, and scroll buttons 214 and 216 for instructing to scroll the contents of the character code selection screen are included. It is. In this example, five sets of character codes and corresponding preview areas are included, and the name of the character code included in each set and the entire preview area are surrounded by a rectangular frame. When the user points with a finger or the like the internal area of the rectangular frame corresponding to, a character code included in the rectangular frame is selected.

  In this way, the character code selection screen displayed for selecting the character code is converted to a part of the phone book data using each character code together with the name of each character code as a selection candidate. Since preview areas 200 to 208 including the resulting character string are included, whether or not the character code is selected correctly before the character code is actually selected and converted to the phone book data (characters are garbled by conversion). Whether or not a character string that has not been obtained can be obtained.

  Next, the character code selection unit 84 determines whether any character code included in the displayed character code selection screen has been selected by a user instruction using the operation unit 60 (step 116). . If no character code is selected, a negative determination is made, and the selection screen display processing unit 82 determines whether or not a page change of the character code selection screen has been instructed (step 118). If a page change instruction using the page update buttons 210 and 212 and the scroll buttons 214 and 216 is not made, a negative determination is made, and the process returns to step 116 to repeat the determination of the presence / absence of a character code selection instruction.

  If any character code is selected, an affirmative determination is made in the determination in step 116, and the character code selection unit 84 changes the character code corresponding to the phone book data (step 120). Thereafter, returning to step 102, the operations after the acquisition of the phone book data are repeated. Instead of acquiring the phone book data every time the character code is changed, the phone book data acquired first and stored in the phone book storage unit 62 may be used. In this case, after the character code change in step 120 is completed, the process may be returned to step 106 for processing.

  Thus, in the hands-free telephone system of the present embodiment, the character string as a result of conversion using each character code is displayed in the preview area on the character code selection screen for selecting the character code. Before selecting the character code and converting it to the phone book data, you can know whether the character code selection is correct and reduce the number of operations when specifying the character code manually. Therefore, the operation can be simplified and the operability can be improved.

  In addition, since the character code selection screen includes a plurality of combinations of the character code name and the preview area, whether or not the conversion is correctly performed corresponding to each of the plurality of character codes is actually determined. Since the comparison and verification can be performed before designating, the number of operations when selecting an appropriate character code from a plurality of character codes can be greatly reduced.

  By the way, it is determined whether or not a part of the telephone directory data corresponding to the preview areas 200 to 208 in the character code selection screen shown in FIG. It needs to be possible. Next, an example of extracting a part of the phone book data corresponding to the preview area 200 will be described.

  (1) The phone book is displayed in step 108 shown in FIG. 3. When the displayed phone book contents are correct (not garbled), the character code determined in step 104 is appropriate. I can say that. On the contrary, since it can be considered that the change of the character code is instructed when the contents of the displayed phone book are not correct, the characters included in the phone book that was displayed when the change of the character code was instructed The telephone directory data corresponding to the column is extracted to create preview areas 200 to 208 in the character code selection screen shown in FIG.

  (2) In the case of (1), for example, consider a case where a character code change is instructed when the phone book screen shown in FIG. 4B is displayed. In this telephone directory screen, the contents corresponding to FIG. 4C are prepared in the hands-free telephone device 50 regardless of the telephone directory data, and the display does not become unnatural. On the other hand, in the contents corresponding to the other phone book data, the name / name corresponding to serial number 5 is composed of alphabets, and the name / name corresponding to serial numbers 6-8 is composed of kanji. . The telephone number is composed of numbers. In such display contents, it is highly likely that a common value corresponds to each of a plurality of types of character codes for alphabets and numbers, and each type of character code corresponds to a kanji character. Therefore, there is a high possibility that different values correspond or no corresponding value exists.

  In this embodiment, there is a high possibility that a common value corresponds to a plurality of types of character codes, such as alphabets and numbers, and a “preview target exclusion range” indicating a common value range, In this way, a “preview target range” indicating a range of values corresponding to different values corresponding to each of a plurality of types of character codes or having no corresponding value is set in advance. Then, when extracting the phone book data corresponding to the character string included in the phone book that was displayed at the time when the change of the character code was instructed, the extraction of the phone book data for those included in the preview target range is performed. Done.

  In addition to the character code values corresponding to alphabets and numerals, the preview exclusion range should include some symbols that are compatible with the different character codes (the same values are supported). May be. Which symbols are included in some symbols depends on whether the values and symbols for each of these multiple character codes are actually determined when multiple character codes to be selected are determined (when designing a product). The correspondence relationship is examined, and if the same value corresponds to a common symbol, this value may be included in the preview target exclusion range each time.

  (3) When the phone book screen shown in FIG. 4 is displayed and the scroll button 104 is pointed and the display content is scrolled, the display of the part newly displayed on the phone book screen is not correct (characters). It can be considered that the character code change is instructed at that time. Therefore, when the change of the character code is instructed, the phone book data corresponding to the character string last added to the displayed phone book screen is extracted, and the preview area 200 in the character code selection screen shown in FIG. It is sufficient to create ~ 208.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, in the above-described embodiment, the character code selection screen includes a plurality of combinations of the name of the character code and the preview area, but this is a case where only one set is included. However, the present invention can be applied. If the contents of the preview area corresponding to this character code are garbled, each page of the character code selection screen corresponding to a different character code is created and displayed one after another. Even in this case, since it is known whether or not the character code is correctly converted before actually determining the character code, it is possible to greatly reduce the number of operations until an appropriate character code is finally selected.

  In the above-described embodiment, the order of the character codes included in the character code selection screen shown in FIG. 5 is not particularly mentioned. However, the order is changed in the order of higher priority (for example, the priority order is higher). The character code selection screen may be created so that a high character code is included in the first page of the character code selection screen or a page close to the first page. As the character code having a high priority, one or more character codes corresponding to the language used in the hands-free telephone device 50 (specifically, the language used in the operation guidance or the like) One or more character codes corresponding to the language most likely to be used in the place where the free telephone device 50 is used (specifically, the official language of the country set as the sales destination of the hands-free telephone device 50) Or a character code that has been selected by the character code selection unit 84 in the past (if there is another character code corresponding to the same language as this character code, these character codes are preferably included) To do.

  In the above-described embodiment, the present invention is applied to a hands-free telephone system as an in-vehicle device. However, the contents of text data included in a CD (compact disc) or the like and tag information included in MP3 data are acquired. The present invention can also be applied to an in-vehicle device such as an audio device that performs display. Alternatively, the present invention can also be applied to a case in which the character code is changed when the data acquired by a personal computer other than the in-vehicle device is not correctly encoded.

  As described above, according to the present invention, a character string as a result of conversion using each character code is displayed in the preview area on the character code selection screen for selecting the character code. Before selecting and converting the phone book data, you can know whether the character code selection is appropriate, you can reduce the number of operations when specifying the character code manually, Operation can be simplified and operability can be improved.
