A dual-camera focusing method and terminal

Abstract

The embodiment of the present application discloses a dual-camera focusing method and a terminal, which are used to improve the focusing efficiency of the cameras. The method in the embodiment of the present application includes: acquiring first focus information of the first camera and second focus information of the second camera; determining the first target FOV of the first camera according to the first focus information, and determining the first target FOV of the first camera according to the first focus information 2. Determine the first optional FOV of the second camera according to the focus information; determine the second optional FOV of the second camera according to the FOV correspondence between the first camera and the second camera, and the first target FOV Select FOV; determine the second selectable FOV from the first selectable FOV and the second selectable FOV according to the first confidence level in the first focus information and the second confidence level in the second focus information The second target FOV of the two cameras controls the first camera to move to a position corresponding to the first target FOV, and controls the second camera to move to a position corresponding to the second target FOV.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a dual-camera focusing method and terminal. Background technique [0002] With the rapid development of smart terminals such as mobile phones or tablet computers, mobile terminals provide more and more help to users in life, work, entertainment, and the like. Among them, the shooting function has become an indispensable part of the mobile terminal, and with the improvement of people's quality of life, people have higher and higher requirements on the shooting effect, therefore, the focusing effect in the shooting process is also becoming more and more important. [0003] In the prior art, for a mobile phone with dual cameras (camera A and camera B), the focusing process of camera A and camera B is independent, and there is no obvious interaction process. Since camera A and camera B do not interact, it is easy to appear Camera A stabilizes quickly, but camera B has a...

Problems solved by technology

[0003] In the prior art, for a mobile phone with dual cameras (camera A and camera B), the focusing process of camera A and camera B is independent, and there is no obvious interaction process. Since camera A and camera B do not interact, it is easy to appear Camera A stabilizes quickly, but camera B has a large amount of bellows phenomenon (that is, the camera searches back and forth, and the user sees clear and blurred changes in the interface), which is very bad for the imaging display of camera B. If Using data that has not been successfully focused will also cause problems in the effect of the photo; in addition to the above problems, there are still problems in the prior art that camera A completes the focus first, while camera B slowly searches for the focus, and it takes a long time to complete the focus, etc.

[0004] For the above two kinds of focusing, the user will see the obvious switching between clear and blurred focus, or see the process of focusing slowly. These focusing processes will make the camera's focusing efficiency low.
