The principle of laser focusing is similar to that of laser rangefinder, which can quickly judge the position of lens and object and quickly complete focusing with the movement of lens. Laser ranging can make up for the shortage of dual cameras in special scenes. If the laser focus area is dirty or blocked, it will be impossible to accurately judge the distance. You can wipe the laser area, laser hole and camera lens under the camera flash. If there are fingerprints, oil stains and other dirt in the window area, it will also affect the focusing speed of the camera, which can be cleaned with glasses cloth.

1. Open the camera of Glory 6plus, and click the three horizontal options above to enter the camera settings; 2. Just check the autofocus box. Huawei Glory 6Plus adopts triangulation or triangulation, and the fastest focusing speed can reach 0. 1 second.

In addition, Huawei Glory 6Plus also supports functions such as focus separation metering and manual exposure adjustment.

The front camera of Glory 8 is fixed focus and the rear camera is autofocus. Distance, subject and light will all affect the focusing effect. If the laser focusing area is polluted or blocked, the focusing will also be affected. It is recommended to wipe the laser area, laser hole and camera lens under the camera flash and try again. If it still cannot be solved, it is recommended to back up the important data of the mobile phone in advance and bring the purchase invoice to the local Huawei after-sales service center for inspection and maintenance. The inquiry method of service center address information is as follows: 1. There is a service center module in the mobile phone service or member service APP of Huawei mobile phone, which can help you find the nearest service center in the networked state. 2. You can also click on the individual user in the lower left corner of Huawei official website, and you can query the address and telephone number of the service center by province and city on the new page. 3. Pay attention to WeChat "Huawei Terminal Customer Service".

Dual camera ranging is to calculate the distance from the object to the camera according to the image content. In the case of no texture area or low illumination, the accuracy of ranging with dual cameras is limited. The principle of laser ranging is different from that of dual camera ranging, which can make up for the deficiency of dual camera ranging in special scenes.
