Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device incorporating a plurality of application software for storing data, and more particularly to an electronic device such as a portable information terminal capable of displaying a list of address data and the like.

[0002]

2. Description of the Related Art PDA (Personal Digital Assistant)
In addition to the schedule function, some portable information terminals can display a list of address information including an address, an address, a telephone number and the like as an address book and can search the address book. For example,
Japanese Patent Application Laid-Open No. Hei 5-145686 discloses a technique for narrowing down one application, address book (FAX) data to search only necessary data, by managing registered destination names and telephone numbers in various fields for each application. , A display device. With the spread of computers, the amount of data handled by individuals has increased dramatically. Among them, the main data content is used as an index, and the data is searched for by displaying a list.

FIG. 14 is a diagram showing a display example of a conventional electronic device, and shows a display example in which registered destination names and telephone numbers are displayed based on address data. The display of the address book includes items of name and telephone number, and telephone numbers corresponding to the names are listed and displayed in alphabetical order. For example,
Starting with the “A” line, the name “Kato” and the phone number “0742-64-xxxx” are displayed, followed by the name “Kadagawa” and the phone number “03-5123-xxxx”, and so on. In the last line, the name "Yoshimoto" and the phone number "03-624"
“3-xxxx” is displayed.

[0004]

However, such a conventional electronic device has a problem in that it is difficult to find the amount of data that continues to expand only by displaying a list using an index. For example, FIG.
If you select the “KA” line on the address book list consisting of the name and telephone number as in 4, the first data in the “KA” line becomes active (see the hatched part in the figure), Subsequent data is displayed on the list. When the user wants to refer to the last “this” data in the “ka” row data, it is difficult to find out immediately.

[0005] The above problem will be specifically described. 15 and 16 are diagrams showing a display example according to a conventional address information list display method. FIG. 15A shows a display example when the data of the selected group exceeds ten.
5 (b) shows a display example when the data of the selected group is less than 10, and FIG. 16 shows other display examples.

In these figures, reference numeral 10 denotes a display screen of an electronic device, 11 denotes an address book list composed of names and telephone numbers displayed on the display screen 10, and 12 denotes a display content of the address book list 11. These are soft keys on the “A” line to the “W” line displayed on the display screen 10 for selection in the order of sounds. FIG. 15A shows a next screen instruction key 13 indicating that the data of the selected group is not displayed and remains. In the figure, a hatched portion indicates that the corresponding key or item is selected and the data is in an active state. For example, FIG.
In the example, the soft keys on the “KA” line are selected by touch keys or the like, and ten data on the “KA” line are displayed.

In a display example 1 shown in FIG. 15, only data within the range of the selected group is displayed. FIG. 15 (a)
In the figure, "GA" is selected by the soft key 12, and ten data (the maximum number of display data in this case) in which the name starts with the "GA" line are displayed. Since the maximum display data number is exceeded, ten data are displayed and the next screen instruction key 13 is displayed. Here, as shown in FIG. 15B, when “Ya” is selected,
Since there are two data items starting with the “ya” line, only two data items are displayed. The disadvantage of this display method is that FIG.
In the case of (b), it is remarkable that only two data items are displayed although ten data items can be displayed.

In particular, the address information has a different data amount and a different data tendency depending on each user. For example, relative address information often has the same last name, and the data of the corresponding name increases. That is, for some people,
Many rows are registered, but "ya" rows are rarely registered. However, the display process of the "A" line and the display process of the "Ya" line are processed without distinction,
Since the number to be displayed at the same time is the same, wasteful display space is created (in the case of the “ya” line), and it takes time to visually search for the address of the target person (“a”).
Row)) occurs. For other display methods,
The buttons for specifying the classification (“A” to “W” buttons) are a method that means the first data of the data to be displayed.

As shown in a display example 2 in FIG. 16, the selected button is “Ya”, but the data in the “Wa” line is also
It is displayed following the data in the "ya" line. The problem of the display method of the display example 2 is that the data breaks (here, “ya”
Line and the "wa" line) are difficult to understand. FIG.
Then, it does not matter much, but when the data amount is large (for example, when there are about 50 data after the “ya” line instead of 4), for example, it is visually checked whether “Yamamoto” is registered. Suppose you search. The name is "Yu",
If the person starting with "yo" is not registered, it is only when the data of the "wa" line is reached that the person named "Yamamoto" is not registered. Glimpse,
It may seem easy to search, but with a full search,
This is surprisingly difficult. This defect also corresponds to scroll processing, that is, display processing when the data next to the currently displayed final candidate in the list display is selected.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and it is possible to easily search for target data, increase operability, and increase processing speed. The purpose is to provide an electronic device that can.

[0011]

According to an electronic apparatus of the present invention, there is provided an electronic apparatus comprising: storage means for storing data comprising a plurality of items; and display means for displaying a list of the data for each item. Sort the data consisting of
Classifying means for classifying into a plurality of continuous data groups; specifying means for specifying an arbitrary data group from the classified data groups; and specifying the plurality of data groups on the display means. The data group specified by the means is displayed in a first display mode, and the data group different from the specified data group is displayed in the second display mode following the data group displayed in the first display mode. Control means for controlling the display in a form.

Preferably, the first and second display modes may have different display colors, respectively, and the first and second display modes may be gradation, hatching, shading, or text. The display may be different in decoration. Further preferably, the data composed of a plurality of items may be address information having a name reading composed of a hiragana or katakana character string as a key item, and the data group may include 5 or more items.
The data may be classified in the order of the zero note.

Hereinafter, the operation of the portable telephone terminal 20 configured as described above will be described. FIG. 5 is a flowchart showing the operation of the control unit 31, in which S indicates each step of the flow. First, it is determined in step S1 whether an incoming call has been received. If an incoming call has been received, an incoming call process is performed in step S2, and the process returns to the start state. That is, when there is an incoming call, the incoming call process is executed with priority, and the address data display process described below waits until the incoming call process is completed. If there is no incoming call, it is determined in step S3 whether various keys of the input unit 22 and the mode switching button 23 have been pressed. When the various keys and the mode switching button 23 are not pressed,
Return to the starting state. When the various keys and the mode switching button 23 have been pressed, it is determined in steps S4 to S8 which key / button has been pressed. First, it is determined in step S4 whether or not the pressed key / button is the enter key 22c. If it is the enter key 22c, it is determined in step S5 whether or not the numeric key 22a has already been input.

If the numeric key 22a has already been entered, a dialing process is performed in step S6 and the process returns to the start state. If the numeric key 22a is not pressed, the process returns to the start state. Step S4 above
If the key is not the enter key 22c, it is determined whether or not the key / button pressed in step S7 is the numeric key 22a. In the case of the numeric key 22a, the input information is held and the state returns to the start state. If it is not the numeric key 22a, it is determined that the input of the numeric key 22a has been completed, and the process proceeds to step S8, where it is determined whether or not the key / button pressed in step S8 is the mode switching button 23. If it is not the mode switching button 23, the state returns to the start state. In the case of the mode switching button 23, processing according to the control table shown in FIG. 6 is performed.

FIG. 6 is a table showing values returned to the control unit 31 when the mode switching button 23 is pressed and control modes. The mode is switched from the normal mode to the address book mode as shown in the control table and the value returned to the control unit 31 when each key / button in FIG. 6 is pressed. At this time, the control of each key / button is switched as shown in the control table of FIG.

Returning to the flow of FIG. 5, in step S9, 0 is input to the register cur indicating the ID number (Addr ID No.) of the current address data (cur = 0), and the current address data is stored first. Data. Then
In step S10, address data display processing is performed, and address book data is displayed on the display unit 21. This address data display processing will be described later with reference to FIG. Next, in step S11, it is determined whether or not a selection process for selecting address data from the address data displayed on the display unit 21 has been selected. When the address data selection process has been selected, a dialing process is performed in step S6.
If the address data selection process is not selected, the process returns to the start state.

FIGS. 7 and 8 are flowcharts showing the address data display processing, and correspond to the processing in step S10 in FIG. First, in step S21, variables num, i, and cat used in the address data display processing are initialized (num = 0, i = cur, cat = 0). There are five variables used in the address data display processing, which are shown in FIG.

FIG. 9 is a table showing variables used in the address data display processing. In FIG. 9, i is the Addr ID variable to be displayed, cur is the current Addr ID No., n
um is the number of address data currently displayed, col
Indicates the display color, and cat indicates the line to which the current Addr ID No. belongs.

Next, in step S22, the current Addr ID
It is determined whether the cur indicating No. is equal to or less than the value of the address data control table (cur ≦ Adr Ctrl Table [cat]). If cur> Adr Ctrl Table [cat], the address data is the current Addr ID. It is determined that the line does not belong to the row to which the No. belongs. In step S23, the value of cat is incremented by one (cat ++), and the process returns to step S22. A row to which the currently selected address data (Addr ID No.) belongs is selected by the processing of steps S22 and S23. Specifically, the address data control table is used to look in order from the “a” line, and if not included in the “a” line, check whether it is included in the “ka” line and find out which line it belongs to. Then the actual display processing starts.

Step S24 and subsequent steps are the actual display processing. First, in step S24, it is determined whether i does not exceed the total number of address data and num is smaller than the total number that can be displayed on the display. If not, the present address data display processing ends. If the above condition is satisfied, the name of the i is set in step S25 based on the address data structure (see FIG. 3).
[I] .name, phone number Adr Data Base [i] .telno,
It is displayed on the num line of the display unit 21. Next, a process of displaying a color on the line is performed by the processes of step S26 and subsequent steps.

FIG. 10 is a table showing constants used in the address data display processing. This constant table stores variables for designating types of colors. As shown in the constant table of FIG. 10, the color types are the display color of the currently selected item (COL_CURRENT), the display color of the same line as the currently selected item (COL_SAME_CATEGORY), and other display colors. (COL_OTHER). Specific examples of the variable names and the display colors of the selected data will be described later with reference to FIG.

Returning to the flow, in step S26, the variable c
It is determined whether or not ur is the currently selected i (i = cur), and if it is the currently selected item, COL_CURRENT is substituted for the variable col in step S27. If it is not the currently selected item, i is set to the current Addr I in step S28.
Address data control Tab corresponding to the row to which D No. belongs
It is determined whether or not i is greater than or equal to le (i ≧ Adr Ctrl Table [cat]) and smaller than the address data control table corresponding to the next row (i <Adr Ctrl Table [cat + 1]). Is the same line as the currently selected item.

If it belongs to the same line as the currently selected item, COL_SAME_CATEGOR is added to the variable col in step S29.
Substitute Y and go to step S31. If the item does not belong to the same row as the currently selected item, COL_OTHER is substituted for the variable col in step S30, and the process proceeds to step S31.

In step S28, num of the display unit 21
The color indicated by col selected in any of the above steps S27, S29, and S30 is displayed in the row. This completes the process of displaying one line. In step S32, i and num are incremented by one (i ++, num ++) to display the next line, and the process returns to step S24. Is performed to determine whether the condition is satisfied.

FIG. 11 is a flowchart showing the address data selection processing, which corresponds to the processing in step S11 in FIG. First, in step S41, it is determined whether or not a key / button has been pressed. If not, the process returns to the start state. If so, it is determined in step S42 whether the pressed key / button is the mode switch button 23. If the key / button is the mode switch button 23, the flow is terminated without selection. Here, as shown in FIG. 6, the mode is switched from the address book mode to the normal mode. If it is not the mode switching button 23 in step S42, it is determined in step S43 whether or not the enter key 22c. In the case of the enter key 22c, the flow ends in the selected state. At this time, Adr Data Base [cur] .tel
The telephone number indicated by "no" is passed to the dialing process described in step S6 of FIG.

If it is determined in step S43 that the key / button is not the determination key 22c, it is determined in step S44 whether the key / button pressed is the numeric key 22a. In the case of the numeric key 22a, Adr Ctrl Table [return value of the pressed numeric key] is assigned to the variable cur in step S45, and the flow advances to step S47. Here, the return value of the pressed numeric key is a return value from the keys shown in the table of FIG. On the other hand, step S4
If it is not the numeric key 22a in step S4, then in step S46, the Next, Prev, and Next shown in the table of FIG.
The value returned when the key 22b is pressed is added.

Next, in step S47, the process proceeds to the address data display process (step S10 in FIG. 5). By executing the above-described flow, when the address book is used, the following address data is displayed on the display unit 21.

FIG. 12 is a diagram showing a display example of the portable telephone terminal 20, in which registered destination names and telephone numbers are displayed based on the same address data as the conventional display example shown in FIG. It is. In the conventional display method shown in FIG.
If you select the “KA” line on the address book list consisting of names and phone numbers, the first data in the “KA” line becomes active (see the hatched part in the figure), and the data after that becomes active. Displayed on the list. When the user wants to refer to the last data of this “ko” in the data of the “ka” row, it has been difficult to find it immediately.

On the other hand, in the present embodiment, since the classification information of the data is configured to be displayed, as shown by the hatched portion in FIG. Is displayed. Therefore, the end of the “ka” line is easy to understand, and the target data can be quickly searched. In this example, since all the data in the row “KA” are classified by color,
Data ("Gouda", 044-611-xxxx) can be searched quickly. The above is an example of a case where the data amount is relatively small. However, in the case of a list display using an index having a larger data amount, the search becomes very easy.

The above effect will be described more specifically. FIG. 13 is a diagram illustrating a display example of a list display method of the address information of the mobile phone terminal 20 according to the present embodiment, which is a display example when the data of the selected group exceeds ten. ).
