The front camera on your iPhone contains a secret weapon. The same tool that everyone uses Best iPhones It can also be used to create Memoji as a night vision camera for video chats. Even when the camera looks completely dark, you can activate your Memoji and your caller will see you completely…albeit with the filter applied. If you know How to set up MemojiYou now have night vision.
The front camera on the iPhone, since iPhone X With a notch in the front, it has what Apple calls a TrueDepth sensor. The TrueDepth sensor is very similar to the technology Microsoft used in Xbox Kinect. It includes an infrared display and a corresponding sensor camera.
The iPhone TrueDepth unit sprays an array of invisible dots onto your face. If you wear glasses that are capable of seeing in the infrared spectrum, you can actually see the dots and the pattern they form. The camera on the iPhone can detect and read points, and it analyzes the pattern to create a 3D model of your face and head.
Our friends in Honestly Apple Get images from Apple’s patent on TrueDepth technology, and you can see in the diagram what an infrared dot projection looks like.
This is how Face Unlock works on iPhone. It uses an infrared camera to map your face, and it matches this map to the original face unlock map you created. This is why a photo of your face should not fool the iPhone. It can recognize depth, so a 2D image shouldn’t work.
Since the camera is infrared, it works in complete darkness. In a black room, the front camera of the iPhone will not be able to take a good picture, but it will be able to turn your head into a rhinoceros, koala bear or talking mound … Well, you can play with augmented reality emojis and Memoji to discover yourself.
How to get night vision in FaceTime with TrueDepth
If you want to use TrueDepth night vision in a FaceTime call, start your call first. The caller will be in full screen mode, and the camera view will appear in a smaller window. Click on that smaller window.
Click the star icon in the lower left corner of the smaller window. This opens the filter menu. You can choose to become a Memoji by clicking on the first icon. If you haven’t created your own Memoji, now is the time.
If you want a more natural look, tap the icon with green, red and blue circles to open the photo filters. The watercolor filter uses the TrueDepth camera. Even in a completely dark room, you’ll be able to share a watercolor version of yourself, in color or black and white.
Will this work on my phone?
The TrueDepth camera is unique to Apple. If you have an iPhone with a notch, from iPhone X and later, or iPhone 14 Pro or 14 Pro MaxYou have a TrueDepth sensor. Your results will definitely vary, depending on how well your iPhone model looks.
We tried this night vision hack with iPhone 14 Pro and earlier iPhone 11. iPhone 14 Pro worked great and provided the screenshots you see in this story. The iPhone 11 could barely make out our face, but even a little bit of lighting helped and produced a successful filter.
Most other phone companies that offer face unlock use simpler image recognition. More luxurious versions of this feature will look to see if your face is moving, or if your eyes are Ramadan, to make sure the camera is seeing a real human and not a photograph.
Apple is unique in using infrared among the major phone manufacturers. Huawei and Xiaomi have used similar technology on phones, but Samsung and Google use a basic camera setting for face unlock on phones like Galaxy S22 and the Pixel 7.
More secrets in the iPhone camera
It would be great to see Apple adopt this technology more and introduce filters that give a more accurate picture of us in the dark, especially for video chats. There is also another secret weapon hidden on the back of the phone that may have similar effects.
The iPhone’s back camera uses a file LiDAR Scanner, which is basically a version of RADAR technology. Using the so-called “time of flight” data, your iPhone can create a virtual map of your surroundings.
So far, Apple uses these features almost entirely for augmented reality (AR) in games and apps. It also helps cameras in autofocus. The TrueDepth sensor shows us that there’s much more potential for IR technology on board, and we imagine Apple is just starting to unlock LiDAR capabilities on the iPhone.
Future Apple AR products, especially apple glasses The wearable will likely rely heavily on these two technologies. It will be interesting to see, literally, how they behave in the dark.
