Abstract

PURPOSE:To quickly display data received through personal computer communication or the like on a display screen by reducing and displaying received data stored in a received data storing means so as to be divided into respective display areas on the display screen. CONSTITUTION:A display device 3 can prepare plural display areas on a display screen under the control of a display control device 5 and can display data in each display area. The device 5 reduces and displays data in each display area and continuously moves (scrolls) plural reduced data displayed on respective display areas based upon a command applied from an arrow key or the like on an input device 7. When a certain display area displaying reduced display data is specified by a cursor whose movement is controlled by the input device 7, a mouse or the like, the reduced display data on the specified display area is magnified and displayed on the display screen by the device 5.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a computer using the present invention, FIGS. 2 to 4 are explanatory views relating to the same embodiment, and FIG. 5 is a flowchart showing the operation of the same embodiment. Figure 1
In FIG. 1, 1 is a CPU, 2 is a storage device, 3 is a display device such as a CRT or liquid crystal, 4 is a communication interface, 5 is a display control device, 6 is a system bus, and 7 is an input device such as a keyboard.

A communication program, a display control program, etc. are stored in the storage device 2, and the CPU 1 has an input device 7
By executing a communication program or a display control program stored in the storage device 2 according to a command or the like from the storage device 2, various communication control or display control is performed. As shown in FIG. 2, the display device 2 can provide a plurality of display areas 9 on the display screen 8 by the display control device 5, and can display data in each display area 9. In the illustrated example, four display areas 9 are displayed on the right side of the display screen 8.

Further, the display control device 5 displays the data in a reduced size for each display region 9, and the data is reduced in the display region 9 in response to a command from an arrow key (not shown) of the input device 7. Data is continuously moved and displayed (hereinafter,
Scroll or scroll display). The display data reduced in each display area 9 is shown in FIG.
As shown in FIG. 5, when the display area 9 is designated by the cursor 10 whose movement is controlled by the input device 4 or the mouse (not shown), the reduced display data of the display area 9 designated by the display control device 5 is displayed. It is enlarged and displayed on the screen 8.

In FIG. 3, the display area 9 designated by the cursor 10 is shown by hatching, and in FIG. 4, the reduced display data of the designated display area 9 is enlarged. In response to a command from the input device 7 or the like, the CPU 1 executes the communication program and the display control program of the storage device 2, etc., is transmitted / received to / from the outside through the communication interface, and the received data received is stored in the storage device 2, It is appropriately displayed on the display device 3.

Next, the operation of the present invention will be described with reference to the flowchart shown in FIG. When a communication command is input from the input device 4 or the like (step S1), the CPU 1 executes the communication program stored in the storage device 2 and data communication is performed via the communication interface 4. In step S2, it is determined whether or not the communication command input in step S1 is a reception command. Step S2
When it is determined that the command input in step S4 is a communication data reception command, the process proceeds to step S3.

In step S3, the received data from the outside is received from the communication interface 4, and in step S4
Is stored in the storage device 2 via the system bus 6. When it is determined that the command input in step S2 is not the reception command, the process proceeds to step S5. Step S5
Then, it is determined whether or not the input command is a display command. When it is determined that the input command is the display command, the process proceeds to step S6.

In step S6, the CPU 1 calls the received data from the storage device 2 and transfers it to the display control device 5. The display control device 5 divides the received data from the storage device 2 into a plurality of display areas 9 of the display device 3 and displays the reduced data (FIG. 2). Assuming that the data area of the storage device 2 is virtually divided into a to l as shown in FIG. 2, each received data of the data area b, the data area c, the data area d, and the data area e is displayed on the display screen 8. 4 display areas 9
a, the display area 9b, the display area 9c, and the display area 9d, respectively, and are reduced and displayed in order. For example, the received data in the data area b is reduced and displayed in the display area 9a, and the received data in the data area c is reduced and displayed in the display area 9b.

When it is determined that the command input in step S5 is not the display command, the process proceeds to step S7. It is determined whether or not the instruction input in step S7 is a scroll display instruction, and if it is determined that the input instruction is a scroll display instruction, the process proceeds to step S8.

In step S8, the received data of the storage device 2 to be displayed is reduced and displayed in the display areas 9a to 9e of the display screen 8 and stored in the display areas 9a to 9b in response to the scroll display command of the input device 7. The received data in the data areas a to l of the device 2 are continuously scroll-displayed. For example, as shown in FIG. 2, the data area b is displayed in the display area 9a, the data area c is displayed in the display area 9b, the data area d is displayed in the display area 9c, and the received data in the data area e is displayed in the display area 9d. When the display area 9 is scrolled upward, the data areas b-c-d are displayed for the respective display areas 9a-9d.
-E, c-d-e-f, d-e-f-g, e-f-g-
Data such as h, f-g-h-i ... are sequentially scroll-displayed.

When it is determined in step S7 that the command is not the scroll display command, the process proceeds to step S9. In step S9, it is determined whether or not the instruction is to enlarge the reduced display of the display area 9. If it is determined that the instruction is to enlarge, the process proceeds to step S10. In step S10, when an enlargement command is input from the input device 7 or the like as shown in FIG. 3, the cursor 10 is displayed on the display screen 8, for example. The cursor 10 can be moved with the arrow keys of the input device 7, and the display area 9 (indicated by diagonal lines) indicated by the cursor 10 is enlarged and displayed as shown in FIG.

If it is determined in step S9 that the command is not a command for enlarging the reduced display of the display area 9, the process proceeds to step S11 and other processing is performed. In this way, by communication with the outside, the reception data received from the communication interface 4 is stored in the storage device 2 via the system bus 6,
The display control device 5 displays the received data of the storage device 2 in a reduced size in a plurality of display areas 9 on the display screen 8 of the display device 3. Further, in accordance with a command from the input device 7 or the like, the display area 9
The reduced display data is scrolled, and the reduced display data is enlarged and displayed by designating the display area 9 having the desired data.

As described above in detail, according to the present invention, the received data received is reduced and displayed in the plurality of display areas 9 of the display screen 8. Therefore, when the display area 9 is scroll-displayed, the display area 9 is displayed. The display data of is displayed in a reduced size, and the amount of data movement per unit time is large compared to the normal display data, so that the desired received data can be displayed in the display area 9 quickly, and further, the display area 9 Since the reduced display data of can be enlarged and displayed on the display screen 8, the received data can be viewed speedily.
