What is Pixel Binning and what does it consist of?



The race to get the best camera and the best photographs is unstoppable and among all the techniques that are being used to achieve it there is one that has been heard for a long time very often, do you know who Pixel Binning is and what it is? We tell you.

In the world of smartphones, photography has become essential and if we talk about digital photography quality we have to talk about pixels, that is, the smallest unit of information that make up our photos.

In photography these pixels are in the camera sensor and are responsible for capturing the light of the scene. The larger the pixels and the more there are, the more light they capture and the better the picture.

However, smartphone manufacturers encountered a problem. They needed to create better photographic sensors but with the smallest possible size so as not to spoil the design of their ultra-thin mobiles. Hey here where the Pixel Binning came up.

To sum it up as simply as possible, the Pixel Binning is a software technology that groups small pixels into a single pixel. In this way, we have four small pixels forming a larger pixel. By joining the pixels four by four and making them work as if they were only one, we managed to store more light or light information and get better photographs.

That is, when we are facing a 48 megapixel sensor in a mobile with Pixel Binning technology, in reality, what we get are 12 megapixel photographs. Yes, this means that we lose resolution, but instead we gain in images with more light and less noise, even in night scenes.

This technique takes time in the market, but lately it has become popular and each manufacturer has proposed its own formula with different names. Huawei, for example, began using Light Fusion in models such as the Huawei P20 Pro where it is achieved that its 40 megapixel sensor has, virtual form, 1.55 micrometer pixels that capture the light better.

Another option would be that of Sony's Quad Bayer or Samsung's Tetracell technology with which they have recently introduced the first 108 megapixel image sensor, along with Xiaomi that has been the first to include it in one of its mobiles, the Mi Mix Alpha, the mobile whose screen wraps around the case.

This is not the only technique with which it is being able to boost photography in today's mobiles. Other phones such as Google Pixel and Samsung Galaxy S10 also get very good pictures even at night but without the Pixel Binning, so we have other alternatives.
