The cameras of our phones have gained in recent years all kinds of sensors. Virtually most of those that hit the market, including the cheapest ones, already have a depth TOF sensor . And thanks to this man and an app that we have known, it is possible to have a night vision camera.
The depth sensors in our phones are essential to make good portraits, since thanks to them you can recognize the physical details of the scene. They are also perfect for making facial scanners, similar to Face ID. Someone has used the functionality these TOF sensors offer to convert your 3D readings into night images .
So you can see through the night with this sensor
Just like we have ever told you that infrared cameras can offer us the functionality of night vision cameras thanks to the properties of these sensors, in those mobiles that have them. In this case they have done something similar in the case of cameras with TOF sensors, since due to their properties they are also capable of seeing in the dark . Well, as we have learned thanks to XDA Developers, there is an app for Android that allows some phones with this type of TOF sensor to be able to see at night.
The app in question is called Night Vision / ToF Viewer . It has just arrived at the Play Store as an early access, but it certainly offers us a quite satisfactory experience.
Although the image you get in the dark is not high resolution, it is more than enough to know where we are moving and what surrounds us in the dark. Of course, at the moment this app is compatible only with a handful of Android phones, so having a TOF sensor and Android 10 are not the only requirements. In order to enjoy this app, it is necessary to have one of these phones , Huawei P30 Pro, Honor View 20, Samsung Galaxy Note 10+, Samsung Galaxy S10 5G or Samsung Galaxy S20 +. Little new compatible mobiles will be added.
How does this app work?
TOF sensors far anticipate us on their behalf. These acronyms stand for Time of Flight , and that is precisely what they are based on. In the time it takes for the rays emitted by the sensor to return when they collide with a surface. When colliding with the surfaces, a three-dimensional map of what surrounds us is generated, and that translated into an image allows us to see what surrounds us in full darkness.
Because in reality it is not seeing what there is, but it is touching what there is, creating an image from that interaction with the environment by the sensor. That is why the image that this camera app with night vision shows us is so basic.
