DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG.
8, the display 40 is connected to the processing device main body 42, and the event processing section 4
4, an enlargement / reduction processing unit 46 and a preprocessing unit 48 are provided.

In FIG. 4, the processing contents of the event processing section 44, the scaling processing section 46, and the preprocessing section 48 are described with reference to a flowchart. In the preprocessing section 48, parameters necessary for the display scaling processing are set. Event processing unit 4
4. The setting is made for the enlargement / reduction processing unit 46 (Step 400 This setting is performed by reading a file containing those parameters).

The parameters include a time for the event processing unit 44 to recognize whether the display enlargement or reduction is designated by continuing to press the mouse button, and the number of the mouse button corresponding to the display enlargement or reduction. , The time interval at which the enlargement / reduction processing unit 46 continuously enlarges / reduces the display, and the amount (magnification) serving as the unit of display enlargement / reduction are included.

When the parameters are set by the preprocessing section 48 (step 400), the event processing section 44 reads the event (step 402) and determines whether or not a mouse button press operation has been performed (step 404). .

When the event processing section 44 confirms that the mouse button has been pressed (step 404).
(Yes), wait until the time set by the pre-processing unit 48 elapses, and determine whether or not the pressing operation of the mouse button is continuously performed (steps 406 and 408: In this example, the mouse button is pressed). The event processing unit 44 determines that the mouse button is continuously pressed when there is no other event, such as when the mouse button is released or the mouse cursor is moved).

When the event processing unit 44 confirms that the continuous operation of the mouse button press has been performed beyond the time set by the preprocessing unit 48 (step 408), the enlargement / reduction processing unit 46 is continuously pressed. It is determined whether the display should be enlarged or reduced according to the number of the mouse button (step 410).

Then, the display is enlarged or reduced by the amount set by the pre-processing unit 48 with the figure displayed at the current position of the mouse cursor as the center (step 412), and whether the continuation operation of the mouse button press is completed. It is determined whether or not there is a next event (steps 414 and 41).
6).

The enlargement / reduction processing section 46 continues the display enlargement / reduction processing when confirming that the pressing operation of the mouse button is continuously performed. When the mouse button press operation ends, the display enlargement / reduction process ends, and thereafter, the event processing unit 44 monitors again whether the mouse button press operation has been performed.

FIG. 5 illustrates the display enlargement operation of the present embodiment. As shown in FIG.
The mouse cursor is moved to the position Z of the figure which is the center of the display enlargement on the screen 30 of FIG. 2 and the mouse button corresponding to the enlargement of the display is kept pressed.

After a lapse of a predetermined time (several hundred msec), the display is enlarged as shown in FIG. 3B, centering on the graphic displayed at the mouse cursor position Z of the button press.

This enlargement is performed continuously when the mouse button is still pressed, and when the displayed figure is enlarged to a desired size as shown in FIG. Is terminated, the enlargement of the display stops at that size. To reduce the display figure, another mouse button is pressed.

As described above, according to the present embodiment, both the designation of the target display graphic and the designation of enlargement or reduction can be performed simultaneously only by pressing the mouse button. It is unnecessary to dispose the buttons 32 and 34 for enlargement and reduction on the top.

Therefore, the operation of enlarging or reducing the display figure becomes extremely easy. In addition, the screen 30 can be used effectively, so that a window can be displayed on the entire screen.

Further, since the enlargement / reduction of the graphic can be stopped by ending the continuous press of the mouse button, the operation of changing the displayed graphic to an arbitrary size can be performed very easily.

Then, a time as to whether or not the enlargement / reduction of the figure is designated by a mouse button press operation, a mouse number corresponding to the enlargement / reduction of the figure, and an interval of a processing time for continuously enlarging / reducing the display figure Since it is possible to set the step size for enlarging or reducing the display figure, it is possible to make the operation environment of the system more comfortable by changing these in accordance with the user's request.

[0032]

As described above, according to the present invention, enlargement / reduction of the screen display and designation of the center position thereof can be performed only by continuing the press operation of the mouse button. Since this button is not required, this operation can be remarkably facilitated, and the entire display screen can be effectively used.
