Cannot detect external Webcam in Matlab - Pls Help me

Hello,

I have installed iball face2face C12.0 Webcam on my laptop. I Use a Dell laptop - Windows 7 OS.

When i type in the imaqhwinfo command i can see 'winvideo', which is supposedly the Integrated Laptop Webcam. I have successfully installed the External webcam and it worked when i used AMCap.exe it's the software i got with the cam.

I tried imaqreset but it did not work. I tried restarting my system but to no avail!!

I request u to help me plss!

Could you post a link to the manufacturer's technical information about that webcam ? I am finding a lot of shopping sites, but not technical specifications.

What do you get if you type:

imaqhwinfo('winvideo')

What does the field "DeviceIDs" say?

i have similar problem

imaqhwinfo('winvideo')

ans =

       AdaptorDllName: [1x81 char]
    AdaptorDllVersion: '4.0 (R2010b)'
          AdaptorName: 'winvideo'
            DeviceIDs: {1x0 cell}
           DeviceInfo: [1x0 struct]

this is the response i get from the matlab

imaqhwinfo

ans =

    InstalledAdaptors: {'coreco'  'matrox'  'winvideo'}
        MATLABVersion: '7.11 (R2010b)'
          ToolboxName: 'Image Acquisition Toolbox'
       ToolboxVersion: '4.0 (R2010b)'

Hi,

I would encourage both of you to contact the MathWorks Technical Support department. http://www.mathworks.com/support/contact_us/index.html

Not all cameras that work with AMCAP are usable from within the Image Acquisition Toolbox and they can help you determine if this is the case with your cameras.
