What gives us a dual camera in the smartphone and why in many modern smartphones two cameras, not counting the front? Certainly this question is asked by some buyers. More and more new products among Android-smartphones and not only equipped with dual cameras. For those who do not know yet, we will try to explain why this was done.

First, let's define the fact that a double camera is a camera with two sensors, which is quite obvious. You can see two cameras. In fact, the module is one, but it is double.

What kind of sensors are we talking about? One of them, as a rule, is quite ordinary. As in any other smartphone, it is a camera sensor that is designed to capture color and highest quality images.

The second sensor serves to capture the data for which the first. Two sensors in a dual camera work in completely different ways. Different manufacturers of smartphones have invested different meanings in dual cameras. The difference lies precisely in the operation of the second sensor.

3D effect Dual cameras can be used to create a 3D image effect. Thanks to the second sensor, you can better analyze the information about the distance of objects. This allows you to make them almost three-dimensional. So, dual cameras are used in Honor 6X and Mate 9 from Huawei.

The Bokeh effect Surely you like portrait photos with a very blurry background. This is the so-called Bokeh effect. In the case of a smartphone, it is possible to shoot such photos thanks to the information from the second sensor.

Augmented reality Thanks to the infrared emitter and the second camera with a wide-angle lens, you can study the reflection of light. It helps bring augmented reality into our lives. See how it works, you can with smartphones Lenovo Phab 2 Pro and Asus Zenfone AR.

Improved detail In the smart phones Huawei P9, Mate 9 and Honor 8 from Huawei found another interesting use of a dual camera. The second sensor of their camera does not capture information about the color. He sees the world in black and white colors. But this is what allows him to focus on details. Colors receive the first sensor, and the second serves to improve the detail of the image.

Shooting under low light Another advantage of dual cameras is that they give you a better shot in poor light. Light is the most important thing in photography. Two sensors capture more details, and they light up later.

Increase with minimal loss of quality Optical zoom is implemented in some smartphones, but not everyone wants to buy them. For the sake of compactness, mobile cameras are usually not equipped with optical magnification. However, when one of the sensors of the dual camera is wide-angle, everything changes. IPhone 7 Plus and LG G5 use dual cameras in order to give users the ability to zoom in without any appreciable loss of quality. Use.
