What are monochrome sensors and what are they for

Monochrome digital - Wild Dog Design

Cameras are one of the most important aspects when choosing an Android phone. Nowadays, the usual thing is that most phones in Spain have several sensors, a combination of different types. One type of sensors that we find is the so-called monochrome sensors or black and white sensors, as they are also known.
Surely on some occasions, you have heard about this type of sensors, or you have a phone that has one of these monochrome sensors. Next, we will tell you all about this type of sensors and the importance they have in the cameras of current Android phones.
What are monochrome sensorsCamera sensors are made up of groups of transistors called photosites, whose function is to capture the light that enters through the lens. Normally these photosites are grouped four by four and each one captures a part of the light, which will then be captured in the final photograph. Each of the photosites specializes in capturing a different color temperature (red, green, and blue). While the room serves as a support.



Most brands use a fourth photosite also in red, although we have seen how brands like Huawei change this, betting on replacing green with yellow. When we talk about monochrome sensors, these photo sites do not have filters to capture a specific color temperature. What they do is measure the intensity of the light that touches them, so that is the only thing they do in this case. Then they convert the intensity into a number, which will be used as an aid when creating that photo.
What are they forTypically, monochrome sensors are used as a backup for the phone's main sensor. While they can take black and white photos, which is another of their main functions, it is that support function that is the most common today. Since the main sensor captures information about the scene, the black and white sensor gives information about the lighting map. The combination of the two allows you to process the image to have a better final photo.

The photos we take have less noise, especially in low light situations. This is possible because the monochrome sensors give us precise information about the scene, helping the photos to be sharper. Also, the contrast is better because you have additional information to separate the pixels. You also get a better dynamic range.
A good way to get better photos, although the final quality will depend largely on the camera software. This is something that will vary significantly between one brand and another, but the monochrome sensors will be a good help so that the photos that are taken with the camera will be better.
