What's the difference between a single camera and a dual camera?

The dual camera consists of a main camera and an auxiliary camera, which is equal to the original dual-core impact single-core processor. A single camera consists of one camera. The differences between them are as follows:

1 is not the same as the blur effect.

The blur effect of single camera combined with large aperture is better than that of double cameras.

2. The effect of night lighting is different.

Dual cameras are two independent modules with their own sensors, so the shooting effect in low light environment is better than that of single camera.

3. Different operability

Dual cameras have two cameras, which are better in operability and playability than single cameras.

Extended data:

1, the dual camera main camera is responsible for shooting; The sub-camera is mainly responsible for measuring the depth of field range and spatial information, so as to achieve fast and accurate focusing in 0.3 s.

2. Better performance in low light environment. Dual cameras can analyze which pixels restore the scene to a higher degree, which can help the mobile phone effectively suppress noise, thus making the picture have better picture quality restoration.

3. The aperture of the mobile phone camera is similar to the lens of the camera, and the value of the aperture is inversely proportional to the aperture. However, due to the limitation of structure and volume, the aperture of the lens in modern mobile phones is generally fixed. So the size of its aperture will directly affect the effect of the camera.
