The PlayStation 4 Camera runs without user login (kernel/system device?) and depends for many of its system functions on the APU, using a tripple buffering system
Available functions:
- photo, video
- depth calculation/imaging
- pad, move, face, head and hand recognition/tracking
- one of the cameras can be used for generating the video image, with the other used for motion tracking.
Back chip connected to Aux port is labeled OV00580-B21G-1C. The OmniVision 580 ASIC is not documented, so it seems it was made specially for Sony out of the 500/600 serie (none of them featuring USB 3.0, see external reference).
Front chip connected to microphone array is labeled 5703 324A.
