Playstation 4 Camera

Specifications

Overview of Technical Specifications
Product Code CUH-ZEY1
External Dimension approximately 186mm x 27mm x 27mm (height x width x depth)
Weight approximately 183g
Cable Length Cord length: 200cm approximately
Connection Type PS4 dedicated connector AUX (USB 3.0-derived)
Capture Range 30cm -
Camera lens Dual camera (move like)
Aperture f/2.0 /fixed focus
Field of view (FOV) 85°
Video Format RAW16/RAW8, YUV422/YUV8 (greyscale)
Video Frame Rate
  • 7.5, 15, 30 or 60fps at 1280x800 pixels
  • 7.5, 15, 30, 60 or 120fps at 640x400 pixels
  • 7.5, 15, 30, 60, 120 or 240fps at 320x200 pixels
  • 7.5, 15, 30, 60, 120 or 240fps at 160x100 pixels
Color depth 12-bit tonal gradation (=4096 tonal levels)
Microphone 4 Channel Microphone Array
Programmable settings

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.
