Apple will equip the entire iPhone 13 series with LiDAR lidar this year, not just the “Pro” model.
Apple has signed an agreement with Sony to guarantee that LiDAR lidar will be used in the iPhone at least before 2023.
LiDAR is the abbreviation of “light detection and ranging”. The first Apple product equipped with this technology is the 2020 iPad Pro. Previously, this technology was mainly used in the automotive industry.
Lidar systems can use light pulses to accurately measure the distance from an object to the camera lens. Using the relevant data, the camera can auto focus more accurately and better distinguish between foreground and background to create effects such as portrait mode. The depth camera will also help augmented reality applications to place digital objects in real environments more realistically.
