Problems solved by technology

[0003] At present, in the process of taking a group photo, the mobile phone camera cannot automatically focus on the face that the user cares about most, but can only use manual focus to focus on the person the user cares about most. Manual focus is based on the user's touch area. This focusing method is not convenient and smart enough, which reduces the efficiency of taking pictures

Abstract

The invention discloses an automatic focusing method and device. The automatic focusing method comprises following steps: obtaining a to-be-photographed object in a viewing frame, obtaining relation information with the to-be-photographed object, determining a target object according to the relation information, and setting a focusing position as the position at which the target object is located. According to the embodiment of the invention, a user does not need to focus manually in the photographing process, namely once manual selection operation is eliminated, the most cared person is focused directly, the photographing process is greatly simplified, and the photographing efficiency is promoted.

Description

technical field [0001] The present disclosure relates to the fields of mobile Internet technology and face recognition technology, and in particular to an autofocus method and device. Background technique [0002] With the rapid development of mobile terminal technology, various mobile terminals such as mobile phones have become very popular, and their functions are increasingly powerful. For example, a user can take a photo with a mobile phone. [0003] At present, in the process of taking a group photo, the mobile phone camera cannot automatically focus on the face that the user cares about most, but can only use manual focus to focus on the person the user cares about most. Manual focus is based on the user's touch area. This focusing method is not convenient and smart enough, which reduces the efficiency of taking pictures. Contents of the invention [0004] In order to overcome the problems existing in related technologies, the present disclosure provides an auto-fo...
