In recent years, multi camera has already become the standard configuration of smart phones. No matter what multi camera combination scheme is adopted, smart phones with a price of more than 1000 yuan have been equipped with more than two rear cameras. Double camera, three camera, four camera and five camera, and one mobile phone has applied for 16 (4X4) camera patents. However, while the number of smart phone cameras has increased, many users have begun to question the practicability of rear multi camera. The more cameras there are, the better it will be to take pictures?

What’s the use of taking more pictures with mobile phones?

At the beginning of the multi camera technology, it was mainly used to solve the problem of the focus segment of smart phones when shooting. Compared with professional cameras that can change the lens or can perform optical zoom through the telescopic lens, the inability to change the focal length once became a problem that hindered the progress of mobile phone photography.

In order to solve this problem, some models try to add a scalable lens structure to the rear camera module of smart phones, but this thick and complex structure is obviously not suitable for increasingly thin mobile devices. Therefore, the scheme of carrying multiple cameras on smart phones has become the mainstream scheme to solve this problem, which is why the early dual camera phones were mostly composed of two lenses, long focus and wide angle.

In the development process of mobile phone rear multi camera, there have been many routes and technical solutions, such as the final synthesis of a photo through multi camera simultaneous imaging, or the use of special auxiliary lens to assist the main camera in imaging, as well as the multi camera scheme design of multi camera to achieve multi focal coverage.

Let’s take a look at the functions of various lenses:

01、Color lens

Standard lens, in most “multi shot” combinations, exists as the main camera; At the same time, there are some enhanced photographic effects, such as “super sensitive” and “high sensitive” lenses that are also excellent for dark photography;

02、Black and white lens

Improve the light input and match with color lens to make the picture more clear;

03、wide-angle lens

Larger shooting makes the photo more spatial and profound;

04、Depth of field lens

With lenses with different apertures, the shooting background is blurred, the subject is more prominent, and the picture is more layered;

05、Telephoto lens

The lens with longer focal length makes the imaging larger and can shoot distant objects;

06、Macro lens

Shoot tiny objects, and focus successfully even at a very short distance;

07、Portrait lens

The focal section of the lens makes the portrait look better;

08、3D depth camera

Complete 3D modeling and provide hardware support for 3D face recognition and AR technology.

What combinations of multiple shots are available on the market?

According to incomplete statistics, there are roughly the following combinations:

Without relevant lens, there is no relevant shooting effect?

Some effects can be presented through later software processing, such as blurring the background of the “depth of field” lens, but the effect may not have a texture directly through the lens. But there are some effects that must be combined with the lens, such as “macro” and “super wide angle”.

For most users, smartphones equipped with multiple cameras provide more possibilities for users to create photos. When users use smart phones to create, they are no longer limited to the focus segment limit of wide-angle main camera, and can obtain the flexibility similar to that of professional cameras in the focus segment selection.

However, due to the limited internal space of the mobile phone, it is expected that the rear multi camera design of smart phones will generally adopt the technical route of not equipped with too many lenses and focusing on improving the imaging quality in the future.

The more cameras you have, the better you can take pictures?

The more mobile cameras you have, the better your picture may not be. There are many factors affecting the photographic effect, such as hardware (pixel, aperture, lens quality, anti shake, etc.), software (algorithm, post synthesis, etc.). The shooting effect will be affected to some extent. Many cameras are not the decisive factor for good shooting effect.
