Ps3 Eye Camera On Usb Hub?

The Sony PS3 Centre Camera

Well boys and girls, I've been working hard last few weeks to make this cracking camera work under Windows.

As you may seen it before, here are the specs:

- 4 aqueduct audio input:16 bits/channel, 48kHz, SNR 90db
- 56º or 75º Field of View zoom lens
- 2.1 F-end, <1% distortion, stock-still focus (25cm to 8 at 75º FOV)
- 640 x 480 at 60 frames/second
- 320 ten 240 at 120 frames/second
- USB.0 loftier-speed data transfer
- Uncompressed video or optional JPEG pinch

This makes the PS3Eye platonic for multitouch applications. The best part is the cost $39.99! I found mine here.

At present, the chief problem with this photographic camera is that there are no drivers for Windows. The camera'southward chipset info is virtually non-real on the web.
Subsequently examining the camera internals (pictures here) I found that it features the OV534-LB50 camera USB two.0 bridge and the OV7720 CMOS VGA sensor. Both of these are made by OmniVision.

I started thinking to my self: "This camera is crawly and it will exist such a dandy and inexpensive replacement for Firefly MV and the like. If we could just go it to work nether Windows..."

Initially, I started poking around with the USB trying to ship some commands to the PS3Eye and see what happens…

Afterwards many long nights I'thousand bringing yous the event:
- Full VGA (640x480) 60fps video capture test app that features uncompressed loftier quality raw video
- Low CPU overhead (since there is no decompression involved on the PC)
- Very low latency (i frame time period)

The camera currently streams video in YUYV format, therefore each frame is 640*480*ii bytes.
At 30fps this amounts to about 17.5MB/s which is pretty low in comparing to the full USB 2.0 bandwidth.
At 60fps the corporeality of data gets higher and it could be affected by other peripherals connected to the USB host controller.
This is why it is recommended that the camera be the merely device connected to the USB host controller.

Well-nigh of the CPU overhead that I currently have is the color conversion code that is implemented in directly C/C++ without whatever SIMD optimizations.
For real (MT) applications this code will get away, since we will be extracting raw grayscale epitome (every second byte of YUYV).

My driver exposes a camera as a device with direct access, thus eliminating the complexities and the overhead of DirectShow organization.
I will be working on custom PS3EYE capture filter for use in TouchLib.
I am currently running Vista and all the code is developed and tested under this particular OS.

Commuter Installation:

- Offset run the Install.bat in Driver directory. Yous might need to reboot your auto after this stride.
- Plug in the PS3Eye camera. Allow the Windows detect the hub and two USB Photographic camera-B3.04.06.1 devices.
- One of these is the sound and the other one is the photographic camera itself. Later a few seconds Windows will automatically discover and install 1 of the USB Camera-B3.04.06.1 devices. This will be the audio device. The one that is left is the photographic camera.
- Windows will prompt you for a driver. Cancel out of that and go to the Device Manager, correct click on USB Photographic camera-B3.04.06.1 device and chose Update Driver Software.
- From there select Browse my reckoner for driver software and select the Driver directory. The PS3Eye Camera driver will be installed.

After successful installation, your Device Manager should look similar to this:

Now run the PS3EyeTest.exe plan, and the captured video also as the FPS counter volition exist displayed.

Become, try it for yourself…

Enjoy!

UPDATE: The assay of the differences between B3.04.06.1 and B4.04.27.1 firmware revealed that the simply divergence between them
is the reported amount of power that the device consumes. This information is stored in configuration descriptor in the camera'south EEPROM.
The B3.04.06.one version reports 10mA and B4.04.27.1 reports 500mA. This alter is due to the fact that in the newer version of the camera the OV538 flake sits direct on the USB charabanc as opposed to OV534 scrap beingness backside the GL850A USB2.0 hub controller chip. To become more details on this read hither.

PS3EyeTest code update!
The test app detects and displays the camera version.
At present you can select the capture resolution and frame rate.

*UPDATE* 10-01-2008
I simply published the early version of PS3Eye Camera DirectShow Capture Source Filter.
Yous can find all the info and download the files here.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*UPDATE* x-05-2008
I made a single PS3Eye Setup application that will install PS3Eye Driver, DirectShow filter and PS3EyeTest
applications all at once. It volition also allow for clean Unistall for those of you that are experiencing problems
with Wink content in IExplorer and Mozilla browsers. For more than info and files go here or here.
