Abstract

The present invention discloses a focal length control method, a focal length control device and a focal length control system and a mobile device. The method includes the following steps that: the mobile device acquires the volume information of voices emitted by a target object; the mobile device determines the distance of the target object from the mobile device based on the acquired volume information; and the mobile device adjusts the focal length of a photographing device according to the distance of the target object from the mobile device. With the method, device and system of the present invention adopted, the technical problem of a poor photographing effect which is caused by manual adjustment of focal length required by an existing mobile device in photographing can be solved.

Description

technical field [0001] The present invention relates to the field of mobile equipment, in particular, to a focus control method, device and system and mobile equipment. Background technique [0002] With the popularization of mobile devices (for example, smart phones) and the continuous improvement of mobile device camera effects, and the convenience of taking pictures with mobile devices, more and more people like to use mobile devices to take selfies on various occasions, especially using selfie sticks Taking selfies is becoming more and more popular. When the mobile device is taken at different distances from the face, the size of the portrait in the selfie image is not the same, and people are used to shouting "eggplant" and other similar words when taking pictures to capture a more satisfactory smile . In this case, if the focal length of the mobile device is not suitable, the size of the portrait in the selfie imaging will be inappropriate, which will affect the selfi...
