Abstract

The embodiment of the present invention discloses a tracking focusing method. During the photographing process, after the target within the shooting range is focused, the first imaging length value and the first driving current value of the target are acquired, and the first driving current value is obtained. The current value is the current value of the current driving motor focusing; according to the preset driving current value, the first driving current value and the first imaging length value, determine the current first image distance value and the actual length value of the target ; After detecting the movement of the target within the shooting viewfinder range, according to the first image distance value and the actual length value of the target, determine the second drive current value for focusing after the target moves, and pass the second drive current value to drive the motor to focus. The embodiment of the present invention also discloses a terminal and a computer-readable storage medium, which can automatically focus on a moving target, improve focusing efficiency and save time.

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...
