Description

A personal terminal available to the extension / reduction of screen and a screen extension / reduction method}

The present invention relates to a personal terminal capable of enlarging / reducing a screen and a computer-readable recording medium recording a method of enlarging / reducing a screen in the personal terminal and a program for realizing the method. On a personal terminal and a personal terminal, one screen can be displayed by zooming out the screen according to the zoom-out command for data that cannot be displayed on the screen. Realizing the screen zooming method and the method for zooming out the screen according to the zoom-out command for the data that cannot be displayed on the screen, and for enlarging the screen according to the zoom-in command for the data you want to see in detail. Computer-readable records of programs for It is about the medium.

Recently, commercially available screens of personal terminals have a fixed size for each personal terminal, and when there are many contents to be displayed on the screen, all the contents cannot be displayed on one screen.

Accordingly, it was necessary to check information that cannot be displayed on one screen by moving up and down or left and right by using a scroll key or a scroll bar on a personal terminal.

As a result, even when it is necessary to display the entire contents at once, for example, even when displaying graphics or the like, it is possible to display only a part of the contents without displaying the entire contents at once.

Therefore, with the introduction of the next generation mobile communication (IMT-2000) service, as multimedia information such as video is frequently used in personal terminals, screen contents can be enlarged or reduced in order to display the corresponding graphics on one screen. The solution is urgently needed.

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned requirements, and a personal terminal and a screen enlargement / reduction method of the personal terminal capable of enlarging or reducing the content of the screen for information that cannot be displayed on one screen and the method It is an object of the present invention to provide a computer-readable recording medium having recorded thereon a program for realizing the method.

That is, according to the present invention, the screen is reduced and displayed according to the reduction command for the data so much that it cannot be displayed on one screen, and the screen is enlarged and displayed according to the enlarge command for the data to be viewed in detail. Zoom in / out the screen according to the zoom-out command for data that is too large to be displayed on one screen in the personal terminal or personal terminal, and enlarge / display the screen by zoom-in command for the data you want to see in detail. It is an object of the present invention to provide a computer-readable recording medium recording a reduction method and a program for realizing the method.
