Hi,

I have a CCD camera that i will be using for image processing and I'm having problems getting MATLAB to find the camera. it is connected to a 64bit dell desktop by firewire. i downloaded the diver (CMU 1394Camera) and the Demo worked fine i could locate the camera and see a preview. however MATLAB is another story, here is what i did:

>> imaqhwinfo
ans = 
    InstalledAdaptors: {'winvideo'}
        MATLABVersion: '7.11 (R2010b)'
          ToolboxName: 'Image Acquisition Toolbox'
       ToolboxVersion: '4.0 (R2010b)'
>> info = imaqhwinfo('winvideo')
info = 
       AdaptorDllName: 'C:\Program Files\MATLAB\R2010b\toolbox\imaq\imaqadaptors\win64\mwwinvideoimaq.dll'
    AdaptorDllVersion: '4.0 (R2010b)'
          AdaptorName: 'winvideo'
            DeviceIDs: {1x0 cell}
           DeviceInfo: [1x0 struct]
>> dev_info = imaqhwinfo('winvideo',1)  
??? Error using ==> imaqhwinfo at 138  
There is no device with the specified DEVICEID.
