The present invention provides a mobile terminal and its focusing method based on touch gestures. The focusing method includes: starting a photographing program to display a preview picture on the touch screen; clicking a focus frame located at the edge of the preview picture and sliding to the focus position; After the touch position reaches the focus position, the movement direction of the focus frame is changed; the photographing program recognizes the change of the focus frame movement direction to focus and judges that the focusing action is over; when the touch action leaves the touch screen, the photographing program controls the camera to take pictures. The focusing method based on the touch gesture provided by the present invention can complete the focusing and photographing actions at one time through the position change of the touch gesture on the touch screen, which simplifies the operation process of focusing and photographing, makes the photographing process more convenient for the user, shortens the focusing time, and facilitates Capture instant images.
Description
technical field [0001] The present invention relates to the technical field of photographic focusing of mobile terminals, in particular to a mobile terminal and a focusing method based on touch gestures thereof. Background technique [0002] More and more smart phones represented by Android have entered the lives of ordinary people. Among them, Android's built-in camera photo application, if the user thinks that it is necessary to manually optimize the focus, generally includes the following steps: [0003] 1. The user starts the camera program to display the preview screen; [0004] 2. The user clicks the area to focus on on the preview screen; [0005] 3.
