Smartphones have become a necessity in today's world which you can gauge by looking at their increasing use, the most successful of these smartphones is the state-of-the-art camera installed in them. The convenience of modern cameras in smartphones has made it extremely easy for people of all ages to take great pictures, and now you can see users taking pictures at every opportunity.
Interestingly, the prices of these smartphones also depend on the innovation of the cameras installed in them, ie the higher the price, the better the camera. However, one of the advantages that is now emerging from smartphones in companies is the provision of more cameras on the back of the same smartphone.
In addition, several companies have introduced a number of smartphones with 3 or 4 cameras installed, while Xiaomi has also introduced a phone with 5 cameras on the back. But do you know what the purpose of the extra cameras in a smartphone is when one camera is enough to take a picture?
Of all the cameras on the back of the smartphone, one camera has the status of a primary camera that focuses on the relevant object when taking a picture. In addition, one of the additional cameras has a wide-angle, which allows it to capture the surrounding scene to a certain extent while taking a picture. It has an ultra-wide-angle camera that captures the surrounding view at a wider angle than a wide-angle camera.
Simply put, this system is such that when a person sees with both eyes, he can see the wide-angle around him, but if he closes one eye and sees with only one eye, he can see the view around the open eye. But not with the eyes closed.
