1. A method for zooming an image displayed on a touch-sensitive screen of a mobile terminal, the method comprising:
setting a zooming mode by default as a zoom-out mode or a zoom-in mode,
measuring a duration of a stationary touch gesture by a user on the touch-sensitive screen, wherein the measuring is performed in response to detecting a first trigger touch gesture by the user on the touch-sensitive screen;
calculating a first zoom ratio value in response to said measured duration reaching a first duration value;
displaying on the touch-sensitive screen said image zoomed by the calculated first zoom ratio value according to the zooming mode;
calculating a second zoom ratio value in response to said measured duration reaching a second duration value which is greater than said first duration value, the second zoom ratio value being different from the first zoom ratio value;
displaying on the touch-sensitive screen said image zoomed by the calculated second zoom ratio value according to the zooming mode; and
switching the zooming mode from the zoom-out mode to the zoom-in mode, or from the zoom-in mode to the zoom-out mode, in response to said measured duration exceeding a maximum duration threshold.
