As the display information to be displayed (reduced), any information other than the above example may be used as the display information. For example, the display information and the display level of the display information as shown in FIG. 11 may be used. Display information may use not only text information but also graphic information.For example, when displaying map information, when displaying information in detail according to the display level, the display area on the screen is reduced and enlarged. It can be realized by displaying information such as place names and facility names at that time, and presenting detailed information.

Next, according to the amount of display information and the display level of the portable terminal, the display level is reflected and the display level is distinguished and the summary / detail (enlargement / reduction) is displayed without changing the display area. Of a display attribute calculation method for the following will be described.

As a display attribute calculation method, as shown in FIG.
There is a method of setting the display attribute itself (character size in this example) of the display information by the designation of the user or the like. However, in this method, display attributes such as character size are set in advance (arbitrarily) in accordance with the display mode of the information. Therefore, even if any display information is displayed, the display mode is the same. Attributes are always the same. Therefore, a method of changing a display attribute such as a character size according to the amount of display information for each display level can be considered.

For example, as shown in FIG. 12, the display ratio on the screen is set for each display information at each display level, and display attributes such as character size are derived from the display area and the amount of display information at each display level. A method is conceivable. However, even in this method, depending on the amount of display information at each display level, the display attributes such as the character size may be reversed between the display levels during screen display (for example, the amount of display information at the display level 1 may be small). Even though the display information amount of the display level 1 is much larger than the display information amount of the display level 2 and the display ratio of the display information of the display level 1 is set to be larger than the display ratio of the display information of the display level 2, the display level 1 May be smaller than the character size of the display information at the display level 2. When the same display level information is displayed in different places as shown in FIG. The character size may be different even at the display level.)

Therefore, for example, as shown in FIG. 13, the ratio of the character size of the information of each display level is set, and the character size is determined from the ratio of the display information amount of each display level to the character size of the information of each display level. (The display ratio on the screen is not fixed as shown in FIG. 12, but the display ratio on the screen changes depending on the display information and the display mode).

For example, an algorithm of a method of setting a display ratio on the screen for each display information of each display level and deriving a display attribute such as a character size from a display area and an amount of display information of each display level (first example) Example) is as shown in FIG.
Note that a specific example of the method of calculating the display attribute of the mark 1 in FIG. 14 is as follows.

(A) When displaying information of display level 1 and display level 2 (display mode 2) Horizontal size of terminal screen: X Vertical size of terminal screen: Y Display level 1 information on screen Display ratio: A ₂₁ Display ratio of display level 2 information on the screen: A ₂₂ A ₂₁ + A ₂₂ = 100 Number of characters of display level 1 information: T ₁ Number of characters of display level 2 information: T ₂ Display level 1 display area of one character of information: one character display area information of S ₂₁ display level 2: S ₂₂ one character display of the display level 1 information area _{S 21 = ((X * Y} ) * (a _{21/100)) / T 1} 1 of character display of the display level 2 information area _{S 22 = ((X * Y} ) * (a 22/100)) / T 2 (b) display level 1 and the display level 2 And information of display level 3 (display mode 3) : The vertical size of the X terminal screen: display ratio on the screen of Y display level 1 Information: display ratio on the screen information A ₃₁ display level 2: A ₃₂ display level 3 of information on the screen Display ratio: A ₃₃ A ₃₁ + A ₃₂ + A ₃₃ = 100 Number of characters of display level 1 information: T ₁ Number of characters of display level 2 information: T ₂ Number of characters of display level 3 information: T ₃ 1 of display level 1 information display area of character: display area for one character of the S ₃₁ display level 2 information: display area for one character information S ₃₂ display level 3: display area for one character information S ₃₃ display level 1 _{S 31 = ((X * Y} ) * (a 31/100)) / T 1 displays one character display of level 2 information area _{S 32 = ((X * Y} ) * (a 32/100)) / T ₂ the display area for one character display level 3 information _{S 33 = ((X * Y} ) * (a 33/10 )) / T ₃ Note, also calculated similarly Otherwise display mode.

In FIG. 14, first, the display level information to be displayed on the screen is specified from the display mode of the information to be displayed on the screen. Next, a display attribute such as a character size is calculated from the display area and the amount of display information for each display level. This is, for example, a display level 1 and a display level 2
The character size of the display information of the display level 1 in the case of displaying the information, the screen size is X * Y, of which the display area of the display level 1 information _{(X * Y) * A 21} /100 , and the display level When divided by the number of characters of information 1, the display area S ₂₁ for one character of information of display level 1 becomes ((X * Y) *
Since _{(A 21/100)) /} T 1 and comprising, identifying / calculated as the character size of the maximum size that vertical / horizontal size of each one character does not exceed (S ₂₁₎ ^1/2. Display information is arranged and displayed on the screen by setting the display attributes.

Also, for example, the ratio of the character size of the information of each display level is set, and the display attributes such as the character size are derived from the ratio of the display information amount of each display level to the character size of the information of each display level. Algorithm of the method (second example)
Is as shown in FIG. A specific example of the method of calculating the display attribute of the mark 2 in FIG. 15 is as follows.

(A) Information of display level 1 and display level 2
(Display mode 2) Horizontal size of terminal screen: X Vertical size of terminal screen: Y Character ratio of information of display level 1 and display level 2:
B_{twenty one}: B_{twenty two} Number of characters of display level 1 information: T₁ Number of characters of display level 2 information: T_Two Display area for one character of display level 1 information: S_{twenty one} Display area for one character of display level 2 information: S_{twenty two} Display area for one character of display level 1 information S_{twenty one}= ((X * Y) * ((B_{twenty one}* T₁) / (B_{twenty one}* T₁+
B_{twenty two}* T_Two))) / T₁ Display area for one character of display level 2 information S_{twenty two}= ((X * Y) * ((B_{twenty two}* T_Two) / (B_{twenty one}* T₁+
B_{twenty two}* T_Two))) / T_Two (B) Information of display level 1, display level 2, and display level 3
Information is displayed (display mode 3) Horizontal size of terminal screen: X Vertical size of terminal screen: Y Information sentence of display level 1, display level 2, and display level 3
Character size ratio: B₃₁: B ₃₂: B₃₃ Number of characters of display level 1 information: T₁ Number of characters of display level 2 information: T_Two Number of characters of display level 3 information: T_Three Display area for one character of display level 1 information: S₃₁ Display area for one character of display level 2 information: S₃₂ Display area for one character of display level 3 information: S₃₃ Display area for one character of display level 1 information S₃₁= ((X * Y) * ((B₃₁* T₁) / (B₃₁* T₁+
B₃₂* T_Two+ B₃₃* T_Three))) / T₁ Display area for one character of display level 2 information S₃₂= ((X * Y) * ((B₃₂* T_Two) / (B₃₁* T₁+
B₃₂* T_Two+ B₃₃* T_Three))) / T_Two Display area for one character of display level 3 information S₃₃= ((X * Y) * ((B₃₃* T_Three) / (B₃₁* T₁+
B₃₂* T_Two+ B₃₃* T_Three))) / T_Three In the case of other display modes, the same calculation is performed.

In FIG. 15, first, the display level information to be displayed on the screen is specified from the display mode of the information to be displayed on the screen. Next, a display attribute such as a character size is calculated from a ratio of a display information amount for each display level to a character size of information of each display level. This is because, for example, when displaying the information of the display level 1 and the display level 2, the character size of the display information of the display level 1 is X *.
Y, the display area of the information of the display level 1 is (X
_{* Y) * ((B 31} * T 1) / (B 31 * T 1 + B 32 *
T ₂ )), and dividing by the number of characters of the information of the display level 1, the display area S ₃₁ for one character of the information of the display level 1 becomes ((X * Y) * ((B ₃₁ * T ₁ ) / (B ₃₁ )). * T ₁ + B ₃₂ *
T ₂ ))) / T ₁ , so that the vertical / horizontal size of one character is specified / calculated as the maximum character size not exceeding (S ₃₁ ) ^1/2 . Display information is arranged and displayed on the screen by setting the display attributes.

FIG. 16A shows an algorithm (third example) of a method for setting the display attribute itself (character size in this example) of the display information by the designation of the user. First, the display level information to be displayed on the screen is specified from the display mode of the information to be displayed on the screen. Next, the display attribute of the information to be displayed on the screen is specified for each display level from the setting of the display attribute. This is, for example,
Character size becomes P ₂₁ of the display information of the display level 1 if (display mode 2) for displaying information display level 1 and the display level 2, the character size of the display information of the display level 2 P
It becomes ₂₂ . Also, next to P ₃₁ is the character size of the display information of the display level 1 when (Display Mode 3) for displaying the information display level 1 and the display level 2 and the display level 3, the character size of the display information of the display level 2 P _32, and the character size of the display information of the display level 3 becomes P _33. This is set in advance as shown in FIG. 16B. If the display mode is the same, the display attribute is always the same. Display information is arranged and displayed on the screen by setting the display attributes.

In the following, according to the amount of display information and the display level of the portable terminal, the display level is reflected and the display level is differentiated and the summary / detail (enlargement / reduction) is displayed without changing the display area. Example of the display attribute calculation method for this will be described.

As the display attribute calculation method, an example of the method of changing the character size has been described above. That is, as shown in FIG. 14, the display ratio on the screen is set for each display information of each display level, and the character size is derived from the display area and the amount of display information of each display level.

Finally, in order to arrange and display the display information on the screen by setting the display attributes, the optimum character spacing is delivered (S99).

In the case of other display modes, the same calculation is performed.

In the method of changing the character size as the display attribute calculation method, the terminal (software) is used as the character size.
However, in the method of changing the character spacing as a display attribute calculation method, the character spacing can be set (changed) in a unit smaller than the character size, so that the actual calculation result is more accurately reflected. it can.

As a display attribute calculation method for deriving the character spacing, for example, when the level of the information to be displayed is changed, another method such as changing only the line spacing according to the amount of display information may be used.

According to the amount of display information and the display level of the portable terminal, the display level is reflected without changing the display area, and the display level is distinguished and the summary / detail (enlargement /
A display attribute calculation method for displaying (reduced) display can be selected by the user. Further, a display attribute calculation method determined in advance according to the display information may be set. When there is no designation, default
Select the display attribute calculation method set in.

In accordance with the amount of display information and the display level of the portable terminal, the display level is reflected without changing the display area, and the display level is distinguished and the summary / detail (enlargement /
As a display attribute calculation method for displaying (reduced) display, a method of changing other display attributes may be used instead of a method of changing a character size and a method of changing a character interval. Also,
A method of changing a plurality of display attributes among these may be used in combination.

According to the display attribute calculation method described above, even if the information display mode is changed (when information having several display levels is displayed in summary / detailed manner), the display area is fixed without changing the display area. Can be displayed.

When the display mode of the information is changed, the information can be displayed by dividing the display level stages after reflecting the display level stages.

For example, by calculating a display attribute such as an optimum character size and a character interval from a character size ratio, a display information amount, and a screen size, different display information can have the same display attribute regardless of display information. A method of reflecting the calculation method / display level stage can be applied.

Furthermore, the optimum character size (display attribute) can be made variable according to the setting of the user, and the way of reflecting the display attribute / display level can be made variable.

Next, according to the amount of display information and the display level of the portable terminal, the display level is reflected and the display level is distinguished and the summary / detail (enlargement / reduction) is displayed without changing the display area. Of switching the display mode of the information displayed on the screen for the following will be described.

For example, as shown in FIG. 26A, when a display mode switching function for displaying summary / detail (enlargement / reduction) is assigned to the up / down operation of the dial, the dial can be moved upward by one step. The display mode is increased by one, and when the dial is moved one step downward, the display mode is decreased by one. Further, as shown in FIG. 26 (b), the scroll button can be operated up / down / left / right, or as shown in FIG.
Outline / Detail (enlarge / reduce) on buttons etc. as shown in (c)
The function of switching the display mode for displaying may be assigned and realized.

By switching the display mode of the information to be displayed on the screen and displaying the necessary display mode information in accordance with the one-touch user's designation as described above, the complexity of switching the display mode can be reduced. Operability can be improved.

When the portable terminal stores the display information (contents) and thereby burdens the disk or memory, the control is performed by using an external medium such as a PD storing the display information (contents). The processing load on the unit 1 and the like is reduced.

The summary / detail (enlargement / reduction) display that reflects the display level and changes the display level without changing the display area according to the display information amount and the display level of the portable terminal of the present invention is as follows. Even in a terminal device other than the mobile terminal (screen display area is narrow), the display level is reflected and the display level is differentiated according to the amount of display information and the display level without changing the display area, and the summary / detail ( (Enlargement / reduction), and the present invention can be applied.

It is needless to say that the steps of the processing shown in FIG. 2, FIG. 14 to FIG. 20, and FIG. 22 to FIG. 25 can be executed by a computer. Computer-readable recording medium, for example, FD
(Floppy disk), MO, ROM, memory card, CD, DVD, removable disk, etc., and can be provided and distributed.

Although the present invention has been described in detail with the embodiment, it is needless to say that the present invention is not limited to the embodiment and can be variously modified without departing from the gist of the invention. No.
