Abstract

The invention relates to an automatic focusing method and apparatus, and belongs to the technical field of photography. The method comprises: during a focusing process, acquiring sound information of an environment; according to the sound information, analyzing a sound source position of the sound information; and performing automatic focusing on a target object at the sound source position. According to the invention, a sounding object is focused through the sound source position; the problem is solved that in a conventional touch control type automatic focusing method, focusing has to be controlled through a touch screen by a user, and in case that the user is at a state when he cannot conveniently operate an electronic device, such as a state when the user holds a tablet device by two hands and a state when the user controls the electronic device by use of a remote controller, automatic focusing cannot be applied; and the effect of normal focusing when the user cannot conveniently operate the electronic device is realized.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to an automatic focusing method and device. Background technique [0002] Focusing refers to the process of changing the object distance and distance position through the focusing mechanism in the camera to make the image of the object being photographed clear. With the rapid development of electronic devices, various electronic devices including shooting functions are used more and more frequently, and people have higher and higher requirements for focusing functions. [0003] An autofocus method provided by the related art includes: during the shooting process of an electronic device, displaying a viewfinder picture through a touch screen; the electronic device receives a click signal from a user on the touch screen, and automatically performs automatic focusing on an object clicked by the click signal in the viewfinder picture; focus. [0004] In the process of implementing...
