Abstract

A zooming method of a display image of an electronic device for zooming in a designated area of a portable electronic device. The zooming method includes the following steps setting a hot key combination, and loading a trigger event of the hot key into a Windows operating system as a monitor event; detecting the trigger event of an input device; if the Windows operating system detects the trigger event of the hot key, the Windows operating system executing a zooming process of the Windows operating system, so as to zoom in or zoom out the display image. Thus, a same set of hot key signals can be used to zoom in/out the designated area in different applications.
