Find out what each camera is for on your mobile and tell them apart.
Nowadays in the market we can find mobiles with two, three, four and even five cameras. Marketing does a lot. The number of cameras or the size of the megapixels makes it possible to sell more mobile terminals.
We have the concept that the cameras of our terminal perform different specific functions. We know that we have a main camera and the rest are secondary, but… do we know what cell phone cameras do? We will explain below What is each camera on our terminal used for?.
The main camera is the one default to mobile phone for snapshots. The incorporation of artificial intelligence allows it to recognize scenes and automatically apply adjustments to get the best shot possible. In some mobiles, this Artificial Intelligence makes it possible to highlight a particular color and leave the rest of the scene in black and white.
If we go into more technical details, the main camera usually has a wide viewing angle. This angle makes it easier to capture the background of the scene being photographed. Normally it is usually around 60º. The focal aperture can vary from f/1.5 to f/2.8 on cheaper phones.
Telephoto lenses have the function of zoom in more. While most smartphone cameras allow you to zoom by cropping the image and enlarging the result, devices with separate telephoto lenses do this optically.
Thanks to the telephoto lens, we managed to the opposite effect of the wide anglesince the telephoto lens brings the image closer to what you want to shoot without losing focus. The difference between this camera and digital zoom is that digital zoom crops the image to enlarge the result using software, resulting in a lower quality result.
wide angle cameras
As their name suggests, these are cameras that have an increased viewing angle. They are normally used in circumstances where what we want to photograph does not come into play. Thus, wide-angle or ultra-wide-angle cameras move the image away, thanks to the wide viewing angle they have.
Therefore, these cameras are ideal for photographing distant landscapes or tall buildings where we want the entire building or landscape to appear on the scene. these cameras they save focus capabilities, by using a fixed focus.
With the intention of improve the amount of detail and sensitivity of photos, some manufacturers include monochrome cameras in mobile devices. By not including a color filter on the sensor of these cameras, the sensors do not different pictures which are combined by the algorithm that each manufacturer uses for images. With this we achieve that different perspectives of the images are captured and we can, at first, achieve better results when taking photos.
Infrared cameras are those that enable thermal imaging. The uses of these cameras are generally varied. The most common It is used to enhance face unlock function. Apple uses this technology to be able to have a better face unlock.
Time-of-flight (ToF) cameras
Time of Flight Cameras or Time of Flight Cameras have a sensor that emits beams of infrared light to measure depth. They calculate the time that elapses since the light reaches the object we are photographing and returns to the sensor again, they analyze the depth of each element of the image.
What we get with this camera is improve 3D scanning. Used for facial recognition because they are cheaper and do not need outside light, they have moved to the back of our terminals to take 3D photos, improving virtual reality Yes creating a more accurate bokeh effect.
macro cameras, allow you to quickly capture small details at very short distances, without losing focus. With this type of camera and a little practice we can get very good captures of everything we can miss with the naked eye. We can take pictures of water drops, plants, animals, among others, to see the smallest details of our world.
Front cameras have several functions in our mobile devices. As we have already said, one of the uses of the front camera is to be able to have facial recognition. Thanks to a ToF camera or an infrared camera, the mobile recognizes our face. Another of the main uses is the be able to take a selfie.
Over time, the selfie camera has progressed and improved. Nowadays the sensors are usually quite high quality and the selfies usually have very good sharpness and resolution. Currently some manufacturers choose to hide the cameras under the screen so that the terminal does not have the notch that we all know.
As we can see, there are many types of cameras in our mobile devices today. The most important thing, sometimes It’s not the number of cameras we have that is the most important. The most important is the work behind. The major companies usually do pretty good post-processing of the captured images to improve the capture and improve the photos.
At the time, Google I used few cameras and took very good pictures. This was all due to the algorithm used to combine the images and get a good result. Let’s also not forget that more megapixels does not mean better photos, since everything depends on the treatment, as they say, that they make of the image obtained.
