Abstract

The present disclosure relates to an autofocus method and device, and the method includes: after the user clicks on the target object in the viewfinder to complete manual focusing, acquiring the first spatial data of the target object; when detecting the viewfinder in the viewfinder When the content changes, acquire position change data; calculate second space data of the target object according to the first space data and the position change data; and automatically focus on the target object according to the second space data. By applying the embodiments of the present disclosure, if the viewfinder moves but the target object does not move out of the viewfinder when the user is taking pictures, the target object can be automatically focused, thereby avoiding the manual focus operation when the viewfinder content changes, simplifying the The focusing operation process improves the focusing speed and correspondingly improves the user's shooting experience.

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...
