What is the use of Huawei's dual cameras?

Compared with a single camera, the advantages of dual cameras in taking pictures are mainly shown in the following aspects:

1. Compared with the traditional single camera scheme, dual cameras have obvious advantages in blurring portrait background (large aperture effect) and sharpness of photos after zooming.

2. It has powerful post-processing ability beyond SLR, and realizes the function of "taking photos first, then focusing" of light field camera.

3. After taking photos, you can readjust the aperture size (F0.95 to F 16) to get new photos with different blurred backgrounds, and even get clearer photos.

4. Filters based on depth information can identify people and backgrounds more clearly and make photos more playable.
