On March 18, previous reports on the new iPhone came out endlessly. Among them, many analysts for the camera upgrade of iPhone 12 thought that Apple would join the ToF lens. Recently, 9To5Mac certified this in the code of the upcoming iOS14.

What is a ToF lens? ToF stands for Time of Flight, and literal translation is the time of flight. This lens sensor consists of two parts, a transmitting end and a receiving end. The transmitting end emits multiple beams of light, and when it hits the object, the reflection is received by the receiving end. The distance between the object and the object is calculated by calculating the time of light transmission, so as to perceive the 3D space structure.
The principle and function of ToF is similar to Apple's 3D structured light, but ToF has a deeper and wider range than structured light. Some mobile phone manufacturers have also used ToF technology to achieve more secure face recognition. Apple's added ToF lens is located on the back of the phone, so Apple may use ToF lenses to enhance AR performance. In addition, ToF lenses can also help take pictures and increase the focus speed when taking pictures.
However, 9To5Mac mentioned that Apple will launch 4 new iPhones this fall, and only two of them support ToF, which may be the higher-priced iPhone 12 Pro and iPhone 12 Pro Max. Therefore, if you want to experience the AR application and better experience brought by Apple's latest ToF lens, you can only spend extra money.
