Predictive Focus Algorithm or PFA for short, provides a method to achieve continuous, high-precision focus during the entire zooming process. When the device is zooming, the technology analyzes the AF value curve transformation law under the subject distance curve, and adjusts different subject distances within the depth of focus, unifying the statistics to engage in precise subject distance adjustment, thus achieving clarity throughout the zooming process. PFA technology has innovatively introduced new methods of judgement to ensure the accuracy and predictability of the direction of subject distance adjustment. The result is a set of advanced focusing algorithms.
