What's the technology behind 4D AF? Is it same as Lytro's multi-aperture technique?
this technology predicts positions of next moment base on current 3D position and speed, that's why it called 4D, 3D + Time
I'm a bit confused of the expressions in those 2 videos. the 1st one says that its AF is predictive. But 2nd one says that it tracks motion.What's right?
Predictive. These engineers never saw Barry Sanders run.
This technique has been used in film SLR cameras before. My Minolta 9000i has this function, hops 25 years ago ...
In the soccer scene, how does it know which player to focus on?
the one closest to the camera.
...or the one, that you select useing the tracking AF feature of those cameras.
probably not the one closest to the camera. see the video.i guess you can select it, but how would one do that when the scene is moving quickly and those cameras come with only a few buttons and no mouse (or touch screen).
