I’m pretty sure all modern fast AF systems have computer vision in their control loop.
- bayindirh 2y agoA7III has a dedicated DSP for focus & tracking, plus it has a computer vision model which can detect eyes and focus for them (even when you have sunglasses it can spot eyes perfectly), moreover you can give 5 faces to it with focus priority, and if it finds any of these faces in the frame, it focus to that one (lower the number, higher the priority). System works at 30 calculations per second, correcting focus 30 times per sec, as required. This is Sony's AF system, 2 generations ago. I'm sure big three can do these tricks, at least at 30FPS. Latest, highest end Sony cameras do it at 120FPS, plus it can track whole body after losing the face, so they can track the same person in the frame after latching to it.
