A term has begun to become popular in the mobile phone industry: ToF camera. If you have researched among the latest mobile phones that have been released, you may have seen how that type of camera slips on occasion between the specifications. But it is not something new, this technology has been used for years, although it is now when it is reaching smartphones.
Although there are few phones that have this ToF camera, this element be very common in the phones of the future, included in yours. So that it doesn't surprise you that your cell phone has a ToF camera, we will explain what exactly it is and what it is for.
ToF cameras: what they are and their functions
A camera with ToF technology -Time of Flight- or flight time camera has a sensor that emits infrared light beams to measure depth. By calculating the time it takes for the light to exit, hit the subject and reach the sensor again, a ToF camera can analyze the depth of each element of the image.
As the name implies, the sensor works by analyzing the flight time, which varies depending on the distance at which the objects are. Ace, An element that is farther away takes longer to receive and bounce the light than one that is closer. Analyzing that information of the arrival of the light, the ToF camera can specify how deep each one of them is.
This technology improves others such as 3D scanning, since with just one infrared light emission you can calculate the depth more quickly and accurately. Also The ToF sensor is cheaper and uses less processing capacity to operate.
The big point in favor of the introduction of ToF cameras in mobile phones is not the price or the processing, but the multiple applications for which it serves. Especially, It highlights its ability for facial recognition, which is much more precise and fast Thanks to this technology, and not need external light.
That is not all, because ToF sensor also improves gesture recognition at terminals, the measurement of distance and volume, the scanning of objects, the experience with augmented reality, the quality of the photographs in portrait mode by better blurring the background and allows night vision with the mobile.
As you can see, ToF cameras are a remarkable advance for multiple functions of the current mobile phones. Although most do not have this technology, their presence will be a majority in the coming years.
