ELECTRONIC DEVICE AND METHOD CAPABLE OF ZOOMING IMAGES |
摘要 |
An electronic device includes a display screen, a processing unit, and a touch panel. The touch panel includes touch sensitive units, and each touch sensitive unit can be identified by an unique coordinate. The processing unit determines whether first two touch sensitive points are touched at the same time, and further determines whether two more touch sensitive points are also touched at the same time within a preset time interval. The processing unit calculates distance between the first two touched points and then a distance between the second two touched points. The processing unit compares the first distance value with the second distance value, and zooms in or zoom out a displayed image according to the result. A related method is also provided.
