In extremely low-light video recording, how does the iPhone's LiDAR scanner specifically improve autofocus performance?

In extremely low-light video recording, traditional autofocus systems, such as contrast detection and phase detection, struggle because they rely on detecting visual contrast or light phase differences within the scene. In the absence of sufficient visible light, these methods lack the necessary information to accurately and quickly determine focus, often leading to slow 'hunting' for focus or complete failure to acquire it. The iPhone's LiDAR (Light Detection and Ranging) scanner specifically improves autofocus performance by directly measuring the distance to objects in the....
