Abstract

The invention discloses an automatic focusing method and device. The method comprises the steps that after a user clicks a target object in a viewfinder to complete manual focusing, first spatial data of the target object are obtained; when it is detected that the viewfinding content in the viewfinder changes, position changing data are obtained; according to the first spatial data and the position changing data, second spatial data of the target object are calculated; the target object is automatically focused according to the second spatial data. By the application of the automatic focusing method and device, in the user photographing process, if the viewfinder moves and the target object does not move out of the viewfinder, the target object can be automatically focused, so that the manual focusing operation during viewfinding content changing is avoided, the focusing operation process is simplified, the focusing speed is increased, and the user photographing experience is improved correspondingly.

Description

technical field [0001] The present disclosure relates to the technical field of communication terminals, and in particular to an autofocus method and device. Background technique [0002] With the development of smart terminals, users can realize various application functions through smart terminals. One of the most common application functions is the camera function integrated on smart terminals. Through the camera function, users can view scenes or people of interest anytime, anywhere. shoot. When the camera function is turned on, after the user takes a view through the viewfinder, the user can use manual focus to focus on the content of the viewfinder by clicking a certain viewfinder in the viewfinder, such as a person's face. [0003] In related technologies, if the user manually focuses and moves the viewfinder, the framing content in the viewfinder will change, and at this time, the camera will automatically focus on the center of the viewfinder. However, since there...
