Description

  The present invention relates to a technique for rearranging data to be displayed in a data processing apparatus.

  A data processing device such as a portable terminal or a personal computer recognizes a character displayed on the screen from a character code assigned to the character. In addition, it has a function of sorting the data of the character string to be displayed in accordance with an instruction from the user or in advance (sort). By appropriately rearranging the display data on the screen, the convenience of the user browsing the screen is enhanced.

As a technique related to rearrangement of display data, for example, there is a technique described in Patent Document 1 described later. In this document, when rearranging a plurality of data, a part of unit data read from each data is extracted as an element, and the plurality of data are arranged based on a comparison result between the extracted element and the reference. It is described that it will be replaced.
JP-A-11-224182

  By the way, there are a plurality of types of character codes such as JIS and Unicode, and the character code used by the data processing apparatus to create a character string depends on the OS of the apparatus. Therefore, data groups created by a plurality of apparatuses having different character codes may include data having different character codes even if they represent similar character strings.

  However, the data processing apparatus originally does not recognize the data having different character codes as the same. Therefore, for a data group in which a plurality of character codes are mixed, when sort processing is performed based on a part of the data as in the technique of the above document, data representing the same character string but different character codes is Each is recognized as separate. As a result, similar character string information may be scattered on the rearranged screen. Thus, when an appropriate rearrangement result cannot be obtained, the convenience of the user browsing the data is impaired.

  Therefore, an object of the present invention is to provide a technique for appropriately rearranging a data group in which a plurality of character codes are mixed.

The data rearrangement method according to the present invention is a plurality of data blocks, and each of the data blocks included therein includes a plurality of reference code systems and one or more types of non-standard code systems. It is checked whether the code system used in each data block included in the data block is the standard code system or the one or more types of non-standard code systems, and the one or more types of non-standard code systems For each data block in which any of them is used as a code system, it is checked whether the non-standard code system used can be converted to the standard code system, and Each non-standard code system included in each data block in which the non-standard code system that can be converted is used is referred to as the standard code system. In other words, data obtained by merging the data block whose code system is originally the reference code system and the data block whose character code system is used as the reference code system by the conversion are merged. performs reordering of the data block in accordance with said reference code system for a group of blocks, the lined sorted by sorting a group of pre Kide Taburokku the upper, not convertable to the reference code system the reference In this method, data blocks using the outer code system are collectively output at a lower level .

The data processing apparatus according to the present invention is a plurality of data blocks, and each of the data blocks included therein includes a plurality of data in which any one of a reference code system and one or more types of non-standard code systems is used. Means for checking whether the code system used in each data block included in the block is the standard code system or the one or more types of non-standard code systems; and the one or more types of non-standard code systems Means for checking whether or not the non-standard code system being used can be converted into the standard code system for each data block in which any one of the standard code system is used, and the standard Each non-standard code system included in each data block in which the non-standard code system that can be converted into a code system is used is the standard. Merging the data block whose code system is originally the reference code system and the data block whose character code system is the reference code system by the conversion, It means for rearranging the data blocks in accordance with said reference code system for a group of data blocks obtained by the merging, sorted by the sorting, a group of pre Kide Taburokku to the upper, the reference Means for collectively outputting data blocks in which the non-standard code system that cannot be converted into a code system is used, in a lower order.

  According to the present invention, it is possible to appropriately rearrange data groups in which a plurality of character codes are mixed. Thereby, the convenience of the user who browses the displayed data group is improved.

  FIG. 1 shows the configuration of an embodiment of the present invention. The mobile phone 1 corresponds to the data processing device according to the present invention. The mobile phone 1 includes an operation unit 2, a display unit 3, a storage unit 4, a voice input / output unit 5, a light emission notification unit 6, a vibration notification unit 7, a terminal control unit 8, and a mobile communication control unit 9.

  The operation unit 2 includes keys and various operation buttons for inputting numbers and characters. The display unit 3 is a display device such as an LCD that displays a screen. The storage unit 4 includes a storage device that stores control information of the mobile phone 1 and data input from the operation unit 2 or received from the outside. The voice input / output unit 5 is a voice input / output device such as a microphone and a speaker. The light emission notification unit 6 is a state notification device such as an LED that notifies the state by lighting. The vibration notification unit 7 is a state notification device that notifies a state by vibration.

  The terminal control unit 8 is a control device such as a CPU that controls the above-described units to operate the mobile phone 1. The mobile communication control unit 9 includes a wireless device 9-1, and executes processing related to wireless communication of the mobile phone 1 in cooperation with the terminal control unit 8.

  The terminal control unit 8 includes a character code recognition unit 8-1, a reference code conversion unit 8-2, and a character code rearrangement unit 8-3 as functional configurations related to the rearrangement of data to be displayed on the display unit 3. In the present embodiment, the character code includes a reference code and other non-reference codes. Which character code is used as the reference code is arbitrary, but for example, when Japanese is displayed on the mobile phone 1, Shift-JIS, which is widely used as a character code for Japanese, should be used as the reference code. Can do. In this case, EUC (Extended UNIX (registered trademark) Code) -JP and the like correspond to non-standard codes even for Japanese.

  The character code recognition unit 8-1 recognizes whether the character code of the data to be rearranged is a reference or non-reference. The reference code conversion unit 8-2 converts the data of the non-reference character code (hereinafter referred to as “non-reference code”) recognized by the character code recognition unit 8-1 into a reference character code ( Hereinafter, it is determined whether or not the data can be converted into “reference code”. For convertible data, the data is converted from a non-reference code to a reference code. The character code rearrangement unit 8-3 performs a sort process on the data that has undergone the processes of the character code recognition unit 8-1 and the reference character code conversion unit 8-2, and the order of data to be displayed on the screen of the display unit 3 To decide.

  The operation of the mobile phone 1 will be described with reference to the flowchart shown in FIG. When an operation for displaying a list of data groups in the storage unit 4 occurs in the operation unit 2, the terminal control unit 8 creates a list according to the following procedure.

  First, the character code recognition unit 8-1 reads data to be listed one by one (step S1). If the data is, for example, a document, only the title of the document may be read instead of reading the entire document.

  Each time the data is read, the reference character code conversion unit 8-2 determines the character code of the data. If the determination result is a reference code (step S2: “reference”), the process proceeds to an inspection of data to be read next (step S5).

  On the other hand, when data of a non-standard code is detected (step S2: “non-standard”), the standard character code conversion unit 8-2 determines whether or not the character code of the data can be converted into a standard code. Then, the non-reference code data determined to be convertible to the reference code (step S3: Yes) is converted into reference code data representing the same character string (step S4).

  Here, for example, a case is assumed in which the reference code is Shift-JIS and the determination target is “good morning” according to EUC-JP of the non-standard code. In this case, the reference character code conversion unit 8-2 converts “good morning” of this EUC-JP into “good morning” of Shift-JIS of the reference code. Accordingly, the mobile phone 1 can recognize “good morning”, which is a non-standard code, as the data of the standard code.

  Of the data of the non-standard code, the data that cannot be converted into the standard code, that is, the data for which there is no corresponding standard code, maintains the current non-standard code (Step S3: No).

  When the above-described processing by the reference character code conversion unit 8-2 is completed for all data to be listed (step S5: No), the character code rearrangement unit 8-3 performs the following for each data group of the reference code and the non-reference code. Execute sort processing within each group. This rearrangement process may be performed on at least a group of reference codes, and non-reference codes may be arbitrary.

  When the rearrangement within the group is completed, the character code rearrangement unit 8-3 further rearranges the reference code group so as to be displayed higher than the non-reference code data (step S7). And the result of the above rearrangement process is output to the display part 3 (step S8). As a result, the list related to the current data group is displayed on the display unit 3 in the order corresponding to the rearrangement process.

"Concrete example"
A specific example is given about the said embodiment. FIG. 3 shows the premise of this example. In this example, it is assumed that the A code as the reference code is included in the B code as the non-reference code (A⊆B). Further, the mobile phone 1 stores a plurality of e-mails in which the A code and the B code are mixed in the order shown in FIG. The illustrated character string is the title of each mail. These titles are the targets of the sorting process in this example.

  The operation of the mobile phone 1 based on the above premise will be described along the procedure shown in FIG. The mobile phone 1 first determines the character code for each mail title. Then, out of the B code titles that are out of the standard, those that can be converted into the standard A code are detected. In this example, only “tomorrow's schedule” described in the B code is detected as being convertible to the A code (step 4a).

  The mobile phone 1 converts the detected “tomorrow's schedule” of the B code into that of the A code (step 4b). As a result, the mobile phone 1 recognizes of 2 and "Tomorrow's schedule" of 1 and "Hello," but, as a group of A code. Then, the A code group is rearranged according to a predetermined rule (step 4c), and the whole is rearranged so that the A code group is displayed higher than any title of the B code (step 4d). Note that a group of non-standard B codes may be rearranged according to the rules of the B code.

  As a result, the titles of the e-mails are displayed on the mobile phone 1 in the order shown in step 4d.

  Thus, according to the present embodiment, if there is character string data common to both codes in the data group in which the reference code and the non-reference code are mixed, they are unified with the data of the reference code. Therefore, it is possible to prevent the data having the same contents from being scattered and displayed in the rearrangement result. Further, since the data of the reference code corresponding to the user's use is rearranged so as to be displayed higher than that of the non-reference code, the convenience of the user who browses the data is improved.

  In general, since a mobile terminal such as the mobile phone 1 is functionally simpler than a personal computer or the like, there are often only one type of character code that can be properly displayed. In such a terminal, by setting the one type of character code as a reference code, data of a non-reference code that is not normally displayed on the screen can be properly displayed. Moreover, since the data of the reference code is displayed at the upper level, even if the screen is a small screen of the mobile terminal, it is possible to quickly browse the properly displayed data.

  The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. For example, in the above embodiment, the processing by the character code rearranging unit 8-3 is executed after the processing of all data by the reference character code converting unit 8-2 is completed (FIG. 2: steps S5 to S6). Instead, the reordering may be updated every time the reference character code conversion unit 8-2 finishes one data process, that is, the reordering may be executed by an immediate process.

  The present invention is not limited to application to a portable terminal, but is also suitable for data rearrangement in an apparatus such as a personal computer having more processing functions than a portable terminal. In addition, the data group to which the present invention is applied is not limited to the e-mail as in the above specific example, but includes various data groups that are required to display a list, such as general document and phone book data. Good.

  Further, the present invention can be implemented as a computer program corresponding to the operation of the mobile phone 1 or a recording medium storing the program.
