Abstract: An electronic device and a method for controlling zooming of a displayed object are disclosed. The method includes: receiving a single-point slide operation performed by a user on a displayed object of a touch screen, and generating a slide signal; parsing the slide signal to obtain a slide track and a feature value of the single-point slide operation; determining whether the feature value of at least one point in the single-point slide operation is greater than a preset value; and when the feature value is greater than the preset value, controlling zooming of the displayed object according to the slide track. A slide track and a feature value of a single-point slide operation of a user are identified, and when it is determined that the feature value is greater than a preset value, zooming of a displayed object of the touch screen is controlled.
