Description

[Detailed Description of the Invention] [Summary] A display control method for a display device equipped with a display plane for multi-windows, in which more windows than the display plane for window display are displayed, the more the number of windows, the more In order to solve the problem that this processing takes a long time, the window display can be made more efficient by dividing the window into several groups and controlling the display by giving display priority within the group and display priority for each group. It becomes possible to process

[Industrial application field]

The present invention relates to a display device equipped with a multi-window display plane, and particularly relates to a multi-window display control method.

For example, a multi-window display in a CRT display device is an effective means for displaying a plurality of pieces of information at the same time.

However, for example, when changing and displaying a multi-window display that is already displayed, it is necessary to process the screen change at high speed in real time in response to the operator's change information input process.

This screen update process tends to become slower as the number of windows increases, and this
Interface (Man Machine Inter
face; MMi) is not preferred.

The practical application of a display method that can more efficiently perform display processing in such cases is awaited.

[Prior Art] ~3- Fig. 4 is a block diagram illustrating a conventional example, and Fig. 5 is a diagram illustrating a processing situation in the conventional example.

FIG. 4 shows a functional block diagram of a CRT display device, which consists of a central processing unit (hereinafter referred to as CPU) 1 that controls various processing operations within the device based on predetermined programs, and various programs used by the CPUI. a keyboard 3 for the operator to input various instructions or various data from the outside; and a window control section 4 for controlling the display of multiple windows; for displaying multiple pieces of information at the same time. The CR7 display unit 8, which has a plurality of display planes, has a window memory 5 (
1) to 5(n), display memories 6(1) to 6(m) that store display information to be displayed in each window, and display memories 6(1) to 6(m) that store the display information to be displayed in each window. It has a display control unit 7 that performs display control, and a plurality of display planes, each of which displays the window and information within the window as a visible image under the control of the window control unit 4 and display control unit 7. The CR7 display screen 8 is configured to include a CR7 display screen 8, and a priority information unit 9 that determines display priority based on internal information.

This example assumes that the number of windows is greater than the number of display planes within the CRT display screen 8. In this case, the fifth
As shown in the figure, the number of windows for the number of display planes (m in this example) is determined based on a certain processing standard (referring to the priority information section 9) from among multiple windows.
, and display under the control of the window control section 4.

That is, the window control unit 4 controls the window memories 5(1) to 5.
(n) is given a certain priority display order, and is displayed on the corresponding display plane for each priority display order.

Next, the display control unit 7 displays (
or to update part of the information displayed in each window), a predetermined display memory 6(i) is taken out from the display memories 6(1) to 6(m) and display or update processing is performed. Was.

It is assumed that all information transfer for performing these display processes is performed via the data bus (al).

[Problem that the invention seeks to solve]

As mentioned above, if the number of windows exceeds the number of display planes that the CR7 display screen 8 has, priority display processing will be performed multiple times to form a multi-window, and this processing will take a lot of time. It will require.

That is, in the case of updating the display information of a window, for example, in the case of the above-mentioned method, all the windows are displayed, and the display contents of the corresponding window are stored in the display memory 6(i) that stores the updated information. Update processing is performed by transferring from.

Also, in order to shorten these processing times, it is possible to prepare a display plane for each window, but in this case, as the number of windows increases, the number of display planes will also increase, and the physical As the configuration increases,
There are problems such as increased costs.

Measures to solve problem C] FIG. 1 shows a block diagram illustrating the invention in detail.

The principle block diagram of the present invention shown in FIG. 1 includes the CPU, display memory 6(1) to 6(m), and CR explained in FIG.
The T display screen 8 and the memory for multiple windows are connected to multiple groups 50(1)~
50 (m), each of which has a display control means (display control unit) 70 having a function of determining the display priority of each of the plurality of groups 50 (the plurality of display memories 6(1) to 6(m)). It is composed of

When controlling the display of windows, first divide the windows into several window groups 50(1) to 50(m), and set the display priority within each window group 50(1) to 50(m) and By configuring the display to be controlled by giving display priority to each group, it becomes possible to process multi-window display more efficiently.

〔Example〕

The gist of the present invention will be specifically explained below with reference to embodiments shown in FIGS. 2 and 3.

FIG. 2 shows a process diagram for explaining the present invention in detail, and FIG. 3 shows a diagram for explaining the processing situation in an embodiment of the present invention. Note that the same reference numerals refer to the same objects throughout the plan.

Window system of this embodiment - 1. A window controller 41 that allocates and displays windows to display planes, and a plurality of windows (window memories 5(1) to 5(n))
is divided into multiple wind groups 50(1) to 50 (m), and each wind group 50(1) to 50
(m) An information section 42 for window groups having information for determining the display priority of the inner windows, and a window group priority information section for storing information for determining display priority for each window group 50(1) to 50(m). 43.

The display control unit 70 also controls the display memories 6(1) to 6(m).
, and a display memory priority information section 72 having information for determining the display priority of the contents of display memos IJ6(1) to 6(m).

Figure 3 shows three wind groups.
0(1) to 50(3), and each window group 50(1) to 50(3) has three windows (i.e.,
Wind memory 5(1) to 5(3), 5(4)
~5(6), 5(7)~5(9) another group).

A display plane within the CRT display screen 8 is provided for each of the line group 50(1) to 50(3), and is determined by referring to the information.

In addition, a plurality of windows (i.e., nine window memories 5 (
1)~5 (3), 5 (4)~5 (6),
5 (7) to 5 (9)), and sometimes each group is
(3), 5 (4) ~5 (6), 5 (
7) to 5(9)) are added to the display priority order.

In this way, the display control unit 7 is placed in the window groups 50 (1) to 50 (3) determined to correspond to the display plane.
0, the contents of the display memories 6(1) to 6(3) are transferred and visually displayed on the CR7 display screen 7.

In the embodiment of the present invention described above, the display information in the window is changed by the corresponding window groups 50 (1) to 50 (
3) Window (window memory 5(1) to 5(3)
, 5(4)-5(6), 5(7)-5(9))
This is possible by reconfiguring the screens only within that group according to the display priority of the group.

〔Effect of the invention〕

According to the present invention as described above, there is an effect that multi-window display can be processed more efficiently.
