Abstract

The invention discloses a method and a device for scaling the display picture of a mobile terminal and the mobile terminal. The method comprises the following steps of detecting contact with a touch screen, and if the contact corresponds to a scaling gesture, obtaining the moving distance and the moving direction of a contact point during the process of contacting with the touch screen; according to the moving distance and the moving direction of the contact point, determining a new scaling level; rendering the display picture of the touch screen according to the new scaling level. By applying the method, the device and the mobile terminal provided by the invention, the smooth scaling of the display picture is guaranteed; moreover, a user can contact the whole interface of the touch screen for scaling operation; the scaling operation area is expanded; the user operation is facilitated; furthermore, a scaling press button or a scaling bar is not needed to be arranged on the display interface of the touch screen, so that the completeness of the display picture is guaranteed.

Description

technical field [0001] The present invention relates to the field of computers, and in particular to a method for scaling a display screen of a mobile terminal, a device thereof, and a mobile terminal. Background technique [0002] At present, users can zoom in and out on touch screen displays (such as electronic maps, pictures, documents, etc.) of mobile terminals (such as smart phones, Pads, etc.). Taking electronic maps as an example, the existing methods for realizing electronic map zooming mainly include the following Two kinds: [0003] Method 1, such as figure 1 As shown, there is a zoom button on the electronic map, and the electronic map can be zoomed in or out by clicking the zoom button, such as clicking the "+" part of the zoom button to enlarge the electronic map, and clicking the "-" part to zoom out the electronic map. The disadvantage of this zooming method is: the zoom level is preset, and the user can only perform zoom operations according to the preset z...
