Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display screen control method in a display device such as a personal computer or a workstation.

The description and drawings are based on a display screen M control method in which the size of the display screen is determined by moving a cursor by one manual input, and the size of the display screen determined by the cursor movement and the preset If the sizes of the two display screens are approximately equal, the screen is displayed with the preset display screen size, so even rough cursor movement can be avoided. To disclose a technology capable of selecting a display screen of a predetermined size close to the actual size.

Conventional 2 For example, on a display screen (hereinafter referred to as a window) of a display device for document processing, the size of the window can be changed by using a size change function provided in the so-called window function. It could be changed freely. However, in fields such as document processing, processing is often performed using standard paper sizes such as A4.35. In that case, if you can change the size freely as described above, it may seem convenient, but in reality, it is necessary to adjust the freely set screen size to the standard size, etc. The disadvantage is that it is complicated in terms of aspects. Furthermore, if the operator desires a standard size,
There is also the operational complexity of having to move the cursor accurately to match the size of the display screen to the standard size.

Problems to be Solved by the Invention The present invention solves the above-mentioned prior art by proposing a display screen control method in which the size of the split display screen can only be changed to a predetermined size in the case of - feet. The task is to eliminate the problems.

As one means for achieving the above-mentioned problem, for example, the display screen control method of the embodiment shown in FIG.
A display control unit 101 that controls the screen display of the display screen 100
, display screen size input means 102, and display screen size storage means 10 for storing a predetermined screen size in advance.
4, comparison and discrimination selection means 103.

In the configuration described in L, the screen size information input from the display screen size input means 1O2 is stored in the display screen size storage means 1.
Screen size stored in 04 and comparison discrimination selection means 1
03, and if the two are approximately equal as a result of the comparison, a screen size of a predetermined size stored in the display screen size storage means 104 is selected and displayed on the screen.

Embodiment J Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of the configuration of the first embodiment. The main memory 8 is used for window status and work for each process. Images for each window are stored in a plurality of window buffers 4. The screen operation processor 3 draws figures, characters, etc. in each window buffer 4. Also, multiple window buffers are synthesized from the information in the window buffer 4 and the CRT
What is displayed on the display section l is the screen composition/video control section 2. The main processor 5 is in charge of controlling the entire display device, and the keyboard 6 performs the control operations according to the present embodiment in accordance with the control procedure stored in the main memory section 8, for example, as shown in the flowchart of FIG. The mouse 7 is used by the operator to operate the window, select functions provided in the window, and perform various processing.

Figures 3 (a) to (C) illustrate the window function that changes the size of the window (hereinafter referred to as the window enlargement/reduction function).
21 in ) is a work area within the window, that is, an area where one figure, table, or character is developed. 22 is a menu area, and various functions of the so-called window can be operated using the keyboard 6.
Menu selection is performed by moving the cursor 24 using the mouse 7 or mouse 70. For example, to select the window enlargement/reduction function, press the keyboard 6 in area 23.
This is done by pressing a predetermined key or pressing a switch 9 on the mouse 7.

To select the window enlargement/reduction function, in this embodiment, move the cursor 24 to the area 23 and press the mouse 7.
When the mouse 7 is moved in this state, the frame of the window to be enlarged or reduced at that time is displayed as shown at 25 in FIG. 3(b). When the user stops pressing the switch 9, the window is enlarged or reduced according to the frame size at that time, as shown in FIG. 3(C).

FIG. 4(a) shows a partial area called WCB of the main memory 8. The WCB contains information regarding the size of one window. That is, Wx and WY in WCB are the sizes of the current window in the X and Y directions. In addition, a TABLE as shown in FIG. 4(b) is also stored in the main memory 8 in advance, and this TABLE manages the size of each standard paper by the size of NX, NY in the X and Y directions. For example, for B5 size, NX1. The value NYl is stored, and the values NX2 and NY2 are stored for A4 size.

Next, the control operation according to the embodiment will be explained according to the flowchart in FIG. First, in step S1, it is checked whether the window enlargement/reduction function has been selected by the switch 9 of the mouse 7.

For example, if such a function is selected by the method shown in FIGS. 3(a) to 3(C), in step S2, Wx of the WCB is set with the upper left corner of the window as the origin.

Display only the window frame according to the value of WY. In step S3, it is checked whether the switch 9 is still pressed, and if it is, the process of step S2 is repeated.

If the depression of the switch 9 is released, the new window size Wx and wy are determined in step S4. That is, the initial values are wx and wy, and the amount of change in the window size is ΔX.

If ΔY, the new window size is Wx+Δx,
4 (b) in step S5.
) TABLEtl-reference, (WX, WY) and (
NX, NY) is also close to fi (+1). Then, in step S6, wx, wy are set as NX, NY of the corresponding paper found in step S5.Finally, in step S7, a new Display a window with a new size based on wx and wy.

In addition, in the first embodiment, the screen size was determined by determining the standard size closest to the input screen size as the display screen size, but there is a certain margin in determining whether it is close or not. However, even if a method is adopted in which the screen size input by the operator is determined as the screen size to be displayed when the size difference is greater than the width of the feet, the effect of the above embodiment can still be obtained. Moreover, the operator has a wider range of screen size selections, resulting in improved operability.

[Effects of the Invention] As explained above, according to the present invention, since the size of the display screen is selected at a predetermined screen size, processing for configuring the screen by the display device is no longer required, and furthermore, the operator This eliminates the hassle of having to perform operations to select a display screen size that is extremely close to a predetermined size when viewed from the side.
