This invention relates to an image data display control method in a display device such as an UBE.

[Conventional technology]

Conventionally, image data is displayed on the screen of a display device such as a CRT by reading out image data stored in a data storage unit and adjusting it to a size that can be displayed on the screen according to a specified display area of the image data. This is done by enlarging and reducing.

As a result, when the image data is enlarged and displayed on the entire CRT screen as shown in FIG. 4, the size of the entire image data is larger than the area of the image data displayed on the CRT screen. The position designated by the data input device has a one-to-one correspondence with the display position on the CRT screen. For this reason, the position of the image data that the data input device can instruct to display is limited to the display position on the CRT screen;
It is not possible to instruct display of the position of image data in an area that is not displayed on the RT screen (undisplayed area) using the data input device.

In such a state, the image data in the undisplayed area is CR
In order to display on the T screen, the current enlarged display state must be changed to full display state where the entire image data is displayed on the CRT screen, or the center position of the enlarged display remains the same and the display state is reduced. After the image data of the area to be displayed is placed on the CRT screen, it is necessary to issue a display instruction by specifying the display position on the CRT screen again using the data input device.

Also, when using a mouse as a data input device,
You have to move the display position by pointing the mouse several times.

Moreover, even if the display on the CRT screen is once displayed in its entirety or reduced in size as described above, the display position may be specified using the data input device or the display position may be shifted using the mouse. It is difficult to immediately display image data of a desired area on a CRT screen.
