In such a way, since the zoom frame 500 can be freely moved, enlarged and reduced to select the zoom object data area and the result of operation can be visually forecasted in advance by comparing the zoom frame 500 with the data display range of the window, the operability is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an overlapping multi-window display system, and in particular, to zoom-up display of circle display data in an active window (window with the highest display priority). and a zoom control method for zooming down display.

[Prior art] Conventionally, this type of method has been used to
As described in Japanese Patent No. 87, a method for enlarging and reducing display data within a window without changing the window size is discussed.

In this method, when enlarging the display, the data is enlarged to the size corresponding to the window size multiplied by the reciprocal of the enlargement magnification, and when reducing the display, the data is enlarged to the size corresponding to the window size multiplied by the reciprocal of the reduction magnification. The data corresponding to the image is displayed in a reduced size.

[Problems to be Solved by the Invention] The above-mentioned prior art does not take into consideration the movement or enlargement/reduction of the target data area to be displayed in an enlarged or reduced size. (1) The target data to be displayed in an enlarged or reduced size (2) It is difficult to visually predict the result of an operation in advance.

The object of the present invention is to overcome the drawbacks of the prior art described above.

The object of the present invention is to provide a zoom control method in which a target data area to be enlarged or reduced can be freely set on a window, and the result of the setting can be visually predicted in advance.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides enlarged display of display data or Means for displaying an operation section for instructing reduced display is provided.

This operation section is, for example, a zoom box provided at the border of the active window.

Further, means for displaying an enlargement operation section for instructing enlarged display and a reduction operation section for instructing reduction display in place of the zoom box when the zoom box is instructed; - Means for displaying an area frame indicating a predetermined range within the data display range of the window is provided.

The enlargement operation section and the reduction operation section are for specifying the zoom type of enlarged display or reduced display, and are, for example, a zoom up box and a zoom down box.

Further, when the zoom box is specified, a movement instruction section for instructing movement of the area frame, and/or an enlargement/reduction instruction section for instructing enlargement or reduction of the area frame. A means for displaying may be provided.

The region frame is, for example, a zoom frame, and is preferably similar to the data display range of the window.

The movement instruction section and enlargement/reduction instruction section are, for example, a zoom frame movement handle and a zoom frame enlargement/reduction handle, where the zoom frame movement handle moves the zoom frame, and the zoom frame enlargement/reduction handle controls the size of the zoom frame. By changing , the data area to be zoomed can be selected.

Further, it is desirable to display the zoom frame by using a rubber band display method that follows the process of moving the zoom frame and instructing enlargement/reduction of the zoom frame.

In particular, only the zoom frame may be displayed without providing the zoom frame movement handle and the zoom frame enlargement/reduction handle. In this case, for example, the zoom frame can be enlarged/reduced by specifying an arbitrary magnification from the outside.

Furthermore, the functions of the zoom frame movement handle and the zoom frame enlargement/reduction handle can be substituted with a mouse.

This means, for example, that you can move the zoom frame with the left mouse button and expand/reduce the zoom frame with the right button, or if you hold down a button inside the zoom frame, the zoom frame will shrink, and if you press the button outside the zoom frame, If you continue, you can make the zoom frame expand.

Furthermore, the present invention provides an enlargement display means for enlarging and displaying the data in the area selected by the zoom frame up to the window frame of the active window when the zoom up box is specified; - A reduction display means for reducing and displaying the display data of the active window to the range of the zoom frame when a box is designated.

For example, the enlargement display means and the reduction means can be realized by application software that maps the zoom frame and the window data display @surroundings.In addition to the enlargement operation section and reduction operation section, it is also possible to A return instruction section may be provided for instructing to return to the state.

According to the present invention, an information processing device equipped with an overlapping multi-window display system having the zoom control method described above can be obtained. This allows the overlap
When running various application software on a multi-window display system, these software can be provided with a zoom control function.

[Operation] When you click the zoom box above with the mouse, the zoom frame above is displayed in the center of the active window, and the zoom box is replaced with the zoom up box and zoom down box above. It will be done.

If you drag the zoom frame movement handle above with the mouse,
The zoom frame moves accordingly, and the zoom frame expands and
When you drag the reduction handle with the mouse, the zoom frame that follows it will be enlarged or reduced.

After determining the data area to be zoomed by the zoom frame in this manner, the user clicks the zoom up box or the zoom down box with the mouse depending on the type of zoom up or zoom down.

When zooming up, the displayed data within the zoom frame is enlarged to the data display range of the window, and the zoom
When the window is down, the data displayed in the window is reduced to fit within the zoom frame.

In this way, the zoom frame for selecting the data area to be zoomed can be freely moved, enlarged, and reduced, so it is highly flexible, and by comparing the zoom frame and the data display range of the window.

It is easy to operate because the result of the operation can be visually predicted in advance.

If it is determined in step 10 that the mouse pointer will not be moved, the zoom frame enlargement/reduction processing in steps 6015 to 6030 is unnecessary and is therefore omitted. In step 6035, the state of the mouse button is captured, and in step 6040, the on/off state of the button is determined. If the button is on, that is, if the button is still pressed, the process returns to step 6005 to continue enlarging/reducing the zoom frame 500, and repeats the same process as above. Furthermore, when the button is off, that is, when the button is released, the process of enlarging and reducing the zoom frame 500 ends.

As a result, the screen changes from FIG. 3(c) to FIG. 3(d). In the process from FIG. 3(C) to FIG. 3(d), the zoom frame 5 follows the movement of the mouse pointer.
00 is enlarged/reduced. A so-called rubber band display is performed.

Returning to FIG. 6, since the zoom frame enlargement/reduction control in step 1045 has been completed, the process proceeds to step 101O.
