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 |
|
| 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.
