First Claim
Patent Images
1. An image swapping method for use in an electronic device supporting multi-touch inputs, comprising:
- providing an image on a touch screen of the electronic device, comprising providing a user interface on the touch screen for receiving a user command to enable an image swapping function;
receiving user commands via the user interface to designate a type of characteristics and a swapping order;
detecting contacts of at least two touch inputs on the touch screen;
determining positions of the touch points on the touch screen;
determining characteristics of image portions in the image corresponding to the touch inputs; and
swapping the characteristics of the image portions according to the swapping order.

Abstract
Patterns displayed on a touch screen are swapped in response to occurrence or movements of touch points on the touch screen. Therefore, when a user of the multi-touch device including the touch screen intends to swap patterns displayed on the touch screen, he or she is merely required to give a few simultaneous touches corresponding to the patterns on the touch screen or to simply move the patterns on the touch screen using simultaneous touches.
