How can I acquire webcam snapshots from a ps3 eye?

I got the driver software from macam(<http://webcam-osx.sourceforge.net/>) and followed their directions to install the macam.component from the .dmg file into the /Library/Quicktime folder like they recommended.

Then I tried installing both the USB Webcams and the OS Generic Video Interface in hope of have access to the webcam. At this point when I call

 camList = webcamlist

I'm only returned with the string

'Facetime HD Camera (Built-in)'

instead of with another external camera option.

imaqhwinfo

Likewise this command returns

ans =

    InstalledAdaptors: {'macvideo'}
        MATLABVersion: '8.4 (R2014b)'
          ToolboxName: 'Image Acquisition Toolbox'
       ToolboxVersion: '4.8 (R2014b)'

instead of multiple cameras to choose as well. Does anyone know how to import the driver software to MATLAB? Or likewise some c-code I could enter that would allow me to use the snapshot() function in MATLAB? Thanks so much!

I have it working on 64 bit windows 10 with driver: https://github.com/jkevin/PS3EyeDirectShow

And the image acquisition toolbox with the Acquisition Using Any Hardware set of functions. That is, use winvideo(); others, like preview() don't work).

Example:

imaqhwinfo
vid = videoinput('winvideo',2)
preview(vid)
[img, ts] = getsnapshot(vid);
save(filename,img);

Hi Sean,

Have you checked compatibility from this page?

Thanks, Madhura

Hmmm no I hadn't checked that page. I saw Sony listed there but when clicked on them I never specifically saw the ps3 eye listed. Would there be any way to capture images from the camera through some C code and then implement that code in MATLAB through a mex file or something?

[Madhura Suresh]

You can do that. MEX files are a wrapper around C code that you can use in MATLAB.

1. What version of OS X are you on? 2. Did you try and use the camera with Quicktime or iMovie? Did it work? 3. If the above worked, you shouldn't need Macam.
