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
voice commands
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 of processors.

The 1-megapixel Image Sensors is speculated to be an CMOS OV9713.

Front chip connected to microphone array, labeled 5703 324A, is a 4-channel 24-bit Analog-to-digital (A/D) converter.
