Michael,

What's the recommended FOV for the PS3 Eye camera?

Thanks in advance for the info.

PS Eye has a two-setting adjustable fixed focus zoom lens. Selected manually by rotating the lens barrel, the PlayStation Eye can be set to a 56-degree diagonal Field of View for close-up framing, or a 75-degree diagonal Field of View for long shot framing (default). Lens is 2.1 F-stop, <1% distortion, fixed focus (25cm to 8 at 75º FOV).

This is official information from Sony, confirmed by our own measurements.

Even though everything I read says that it is designed for the PS3 and says nothing about plugging into a computer....you can do it and it will work good???

Yes. It's a USB device, and so long as you have a compatible driver installed, it will work. Code Laboratories has a free PS3 Eye driver that's supposed to be compatible.

I haven't tried this yet, but I got the PS3 cameras a couple of weeks ago and will get to my next round of testing very soon.

when calibrating 1 of my PS3 cameras with iPi calibration software I got: 52.03711 for FOV
if it helps anyone...sadly, I still have nowhere to set up my 4 cams for more reasonable testing
right now. :(

You'll probably want to adjust the lens to the wider 75 degree setting. See above for more info. Just for comparison, the Logitech Quickcam Pro's FOV is about 74.

Hi Greenlaw,

Thanks for that info....curious tho, does iPi do better with a wider FOV and greater distortion?
Or is it an issue of providing more area/real estate for the camera to pick up the actual movement?

Distortion refers to a form of optical aberration and has nothing to do with FOV.

http://en.wikipedia.org/wiki/Distortion_(optics)

Usually you should want as small distortion as possible, no matter what FOV you have.

The only difference between 56/75 degrees setting in PS Eye camera is how much area can you use as capture volume.

Hi, i got my 4 ps3 eyes, and they seem not to work with usb hub, 5m passive usb extenders and even 2 connected 1,8m extenders(3,6m). So i think as it has 2m cable on its own, maximum passive extender would be 3m) Have to order active extenders.
Also when i try to record a video with 640*480 resolution ipirecorder stops recording after a few seconds, even though the space on hdd is enough. But it works on 320*240 ok.
I'll post more of my newbie testing later)
