Abstract

The embodiment of the invention discloses a tracing focusing method. The method comprises the steps of during a photographing process, after the operation of focusing on a target within a photographing range is completed, acquiring a first imaging length value and a first drive current value of the target, wherein the first drive current value is a current value for driving a motor to focus on; determining a current first image distance value and a target actual length value according to a preset drive current value, the first drive current value and the first imaging length value; and after the movement of the target in the photographing range is detected, determining a second drive current value after the target moves according to the first image distance value and the actual length value of the target, and driving the motor to focus on via the second drive current value. The embodiment of the invention also discloses a terminal and a computer readable storage medium. The moving target can be automatically focused on, the focusing efficiency is improved, and the time is saved.

Description

technical field [0001] The present invention relates to focusing technology in the field of image shooting, in particular to a tracking focusing method, a terminal and a computer-readable storage medium. Background technique [0002] With the continuous development of electronic technology, the development of terminals with a shooting function, especially the camera equipment, is also advancing by leaps and bounds, so that users have higher and higher requirements on the shooting function of the camera equipment. In the prior art, in the process of using a terminal to take pictures, it is usually necessary to focus on the shooting target. However, when the shooting target moves, it takes a long time to focus and the focusing efficiency is low. Contents of the invention [0003] In order to solve the above technical problems, embodiments of the present invention provide a tracking focusing method, a terminal and a computer-readable storage medium, which can automatically fo...
