Why should a mobile phone be equipped with dual cameras?

Nowadays, many mobile phones are dual cameras, so this design is definitely beneficial. The function of the camera is to take pictures, and the quality of the camera ensures the quality of this photo.

First of all, two cameras can effectively improve the shooting effect in low light. The images of two cameras with different aperture parameters are compared and adjusted to the value closest to the real scene, thus effectively suppressing noise. Two small cameras can achieve the shooting effect close to one big camera. Due to the limitation of smartphone thickness, it is impossible to insert the next high-end lens. Two cameras can balance the contradiction between effect and module thickness. ? Secondly, double shooting can also make photos more effective. Dual cameras can capture more details of the scene, and at the same time, with large pixels and large aperture, better photo effects can be obtained. ?

Secondly, there is the advantage of 3D effect that once appeared briefly. ? Under the interaction of two lenses, the system can automatically analyze different depth of field. ? Although the word 3D has been over-consumed, people are dismissive, but on this basis, it can still realize the functions of background blur, autofocus, real-life expansion and so on, and the effect is obvious. ? However, although the dual cameras have brought us a better photographic experience, they also have some shortcomings. ? For example, many mobile phones support the background blur function, but if the main body of the characters is not on a plane, only some characters remain clear and other parts are blurred. ? In addition, when shooting scenery, it is often futile and unintelligible.

Generally speaking, dual cameras are more common and quality for people, which improves the user's good experience and makes the mobile phone look more advanced.
