What is binarization and how it helps to make your photos better

In recent years, when it in some article, video or presentation came on the capabilities of the camera of the next smartphone, you probably have heard or seen terms like pixel binning, binarization or technology enterprises of pixels. As you know, it’s all one technology, but what it is and why do we need, we will try to understand this material.

What is a pixel?

To understand what is binarization (technology Association of pixels), you first need to understand what, in this context, pixels. Pixels are physical elements on the camera sensor, which capture the light during shooting.

The larger size of the pixels is measured in micron (ppm meter), and the pixel size of one micron or less are considered small. For example, the camera of the iPhone XS Max, Google Pixel 3 and Galaxy S10 have large pixel size of 1.4 microns.

I think no need to explain that the larger the pixel size, the better, because the larger pixels can capture more light, and this, in turn, a sure sign of a good photo. Especially the difference cameras with large and small pixels visible when shooting in low-light conditions. If you shoot somewhere indoors or on the street, but in the evening or at night, in order that the photo came out like Malevich’s Black square, the camera needs to capture more virtually absent in these light conditions, but if the pixels on the sensor to be sufficiently large, and the lights not be able to collect as a result, the picture will come out dark and with a large amount of noise.

But if the pixels in the camera do large, and the size of the camera module greatly from this increase. You can not increase the module size and increase the pixel size, but then those big pixels in the small module will fit a bit, and the photo resolution in this case will suffer. For the modern slim and elegant smartphone need the same slim camera, and preferably from the body is not sticking. In such circumstances, producers have to try to sit on two chairs at once (the camera smaller, but the pixels are bigger) – and here it came in handy technology called binarization.

Binarization is one of the most important technologies in contemporary photography

In General, the binarization is the process of combining information obtained from the four pixels as if it was received one large pixel. Thus, a photograph taken on a camera with a pixel size of 0.9 microns will correspond to what might make a camera with large pixels 1.8 microns.

The reverse side of this coin is four times reduced resolution photos, which is due to the merging of four small pixels in a large one. This means that mobile camera with high by modern standards the resolution of the sensor 48 MP involved in technology binarization output capable of delivering the resolution of only 12 MP. Now remember that some smartphones resolution camera is only 16 MP, which means that when you combine pixels for better picture in the dark, we get the picture, the quality of which will correspond to the camera with a funny 4 MP.

In General, pixel binning is made possible through the use of sensors in cameras of the so-called Bayer filter. The Bayer filter is a two – dimensional array of color filters, photodiodes which are covered with all modern image sensors available. This filter is used to obtain a color image in the matrices of digital cameras, camcorders, and scanners. A standard Bayer Filter, which is used in your smartphone comprised of 25% red elements, and 25% blue and 50% green elements. According to Cambridge in Color, this filter is designed to simulate the human eye, whose sensitivity is highest to green light it. As soon as the camera sensor captures the image, it is interpolated and processed to produce the final, full-color images.

In combination with the Bayer Filter technology enterprises of pixels gives us the opportunity to do high resolution photos in daylight and photos to a smaller resolution, but also with less noise and a high level of brightness in low light conditions.

Who already uses the binarization?

If the manufacturer has a smartphone with camera 32 MP 40 MP to 48 MP, you can certainly be sure that it uses technology combining pixels. The currently known devices with this technology are the Xiaomi Redmi Note 7, Xiaomi Mi 9, Honor View 20, 4 Nova Huawei, Vivo V15 Pro and ZTE Blade V10.

As I mentioned above, in the market there are smartphones with cameras of lower resolution, but using the binarization. Among these smartphones ThinQ LG G7, LG ThinQ V30s, Xiaomi Redmi Mi S2 and A2. The LG smartphone has a Super Bright mode, which allows you to make 16 MP-sensor bright night 4 MP-photo.

It is obvious that cameras with higher resolution are more suitable for the above technology (especially basic and not the front, of the camera), as the output resolution with the cut four times as much. Fortunately, after the recent news from the manufacturer of mobile processors Qualcomm that the company has implemented in their chipsets support cameras with resolution more than 100 Megapixels, by the end of this year we expect to see the first smartphones with the new mind-blowing cameras.
