[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings.

Prior to the description of the present invention, a portable terminal device to which the present invention is applied will be described. FIG. 2 shows a circuit configuration of the portable terminal device.

A central processing unit (CPU) 1 reads a system program and a user application program stored in a program memory 2 and executes an operation to perform system control and input processing of information to be transferred to a host device.

A subsystem program for displaying a window is prepared in this system program. A well-known program can be used as the window display program itself. Regarding the window display, the difference between this embodiment and the conventional example is as follows.

1) The display information storage area used for the window can be variably set.

2) In order to inform the user of a specific window screen in the window display screen, the window is highlighted.

In order to perform such processing, the control procedures of FIGS. 4 to 6 are prepared and stored in the program memory 2. The work memory 3 stores data used for arithmetic processing of the CPU 1 and information displayed on the display device 4.
The storage area of the work memory 3 is provided with a system area that stores data related to system control and a user area that is released to the user side for user applications.

In the system area 11, an area (see FIG. 3) 11A for storing display information (window information) to be displayed in a window and an area (not shown) for synthesizing each window information are provided exclusively. There is. Further, in this embodiment, it is possible to set the window information storage area (see FIG. 3) 12A in the user area 12 according to an instruction from the user. The window information storage area 12A is used for storing other information when there is no instruction for use from the user.

The display device 4 has a work memory 3 in accordance with a display system program periodically executed by the CPU 1.
The screen display information stored therein is received from the CPU 1 and displayed visually.

The input device 5 such as a keyboard is a CPU 1
And the information to be transferred to the host device is input when the application program is executed.

The serial communication interface 6 is connected to the host device via the signal line 7. The signal line 7 can be attached to and detached from the apparatus body.

The window display processing executed in such a circuit configuration will be described with reference to the flow charts of FIGS.

In the operation instruction related to the initial processing in the application program, the user describes in advance a command for instructing the window information storage mode. In this embodiment, any one of a) a first mode using only the system area 11 of FIG. 3, b) a second mode using the system area 11 and the user area 12, and c) a third mode using only the user area. Make a designation.

When the application program is executed, C
The PU 1 identifies the operation instruction described in the application program by the instruction identification program of FIG. 4, and executes the processing according to the identification result. The window information storage mode instruction described above is also identified, and the parameter indicating the mode is stored in the system area 11 in the work memory 3 (S10 → S20 → S25, S30 → S35, S40 →
S45). When a window is displayed according to an instruction in the application program (S10 → S55 → control procedure of FIG. 5), the CPU 1 refers to the above-mentioned parameter value, sets the memory storage address corresponding to the mode indicated by the parameter value, Display information instructed by the application program is stored in the system area 11 and / or the user area 12 in the work memory 3. For example, the second
When the mode is designated, the CPU 1 detects the designation of the second mode by the control procedure of FIG. 5 every time the window display is instructed by the program command in the input device 5 or the application program (step S110 of FIG. 5).
(S120), the display information for the first window is written from the start address of the fixed area allocated for the window in the system area 11. Further, the storage address of the first window information is stored in the system area 11 as directory information. This directory information is used at the time of screen compositing at the time of overlapping display.

Further, the CPU 1 confirms that the write address is within the allowable address range corresponding to the designated mode before writing the information in the above area. In the case of writing in the second mode, it is detected by the write address that the window allocation area in the system area 11 is full, and then the write address is switched to the window allocation area in the user area 12 ( S125). In the case of designating the first mode, when the window allocation area in the system area 11 becomes full, writing of more information is prohibited. Further, in the third mode, the window display information is written from the predetermined start address of the window allocation area in the user area 12 (S135).

In this way, every time the window display information is newly written in the window allocation area, the CP
U1 converts the newly written window information from the character code into a dot pattern and overwrites it in the screen display area in the work memory 3 to update the information group for one screen for display (step S140). .

At this time, the CPU 1 executes the control procedure of FIG. 6 and confirms that the information newly written in the screen display area is the latest window information, that is, the information to be displayed in the front row (FIG. 6, step S210), and a thick frame graphic pattern for emphasis as shown in FIG. 1 is added around the frontmost window.

With respect to the display information of the screen display area, the position of the window which has been in the front row up to now is detected by directory information or the like, and the graphic pattern for emphasis is erased. Since it is read by the CPU 1 and transferred to the display device 4, only the window in the front row is highlighted in a bold frame on the display screen of the display device 4, as shown in FIG. For this reason, since the boundary between the window in the front row and the window immediately after it is specified, the information in the window becomes easy for the user to see.

In addition to this embodiment, the following example can be carried out.

1) Although a thick frame pattern is added to the window screen to be emphasized in this embodiment, a shadow graphic pattern as shown in FIG. 7 may be added. It is also possible to use a frame-like pattern as the emphasized graphic pattern.

2) In this embodiment, an example is shown in which the emphasized graphic pattern is switched and displayed every time a window screen is added. However, the highlighted graphic pattern is switched to the next-stage window as the window screen in the front row is erased. It goes without saying that it will be displayed.

3) In this embodiment, the thick frame graphic is added to the window screen in the front row, but not limited to the window screen in the front row, a specific window screen is displayed to the user from the device side in application processing. When the user wants to be informed, it is advisable to add an emphasizing graphic pattern to the particular window screen. In this case, refer to the directory information for each window screen (the start address of the area that stores the information to be displayed in the window and the information that indicates the window type), and the position of the window to be highlighted in the display screen. Is detected by the CPU 1, and an emphasis graphic pattern corresponding to the position is added to the information group of the screen display area.

4) In the present embodiment, even if only one window screen is displayed, it is highlighted. However, when the number of displays is two or more, it is possible to highlight it. In this case, the number of displays is updated and stored each time a window screen is added or the display is erased, and the presence or absence of highlighting is determined by the CPU 1 based on the value indicated by the number of displays.

5) Not only the overlapping display of window screens,
When displaying individually, the active screen (window screen in the input mode) can be highlighted with a thick frame. In this case, each time the input mode is switched, the window corresponding to the input mode is detected and the window is highlighted.

[0038]

According to the first aspect of the present invention, the specific window screen can be distinguished from the other window screens by the emphasizing graphic pattern, so that the position of the specific window screen can be easily understood by the user.

According to the second aspect of the present invention, by storing the information of the window screen and other information, it is possible to display a large number of window screens without increasing the size of the memory.

According to the third aspect of the present invention, since the information storage area of the window screen can be selectively used, the degree of freedom in constructing the memory address space is increased.
