It looks like you don't have videoinput function in your installation. You need to have Image Acquisition Toolbox to have that function. You can do
>> ver
to verify what you have.

Your ver() output confirms that you don't have the Image Acquisition Toolbox installed, as Honglei Chen describes. Thus, you won't be able to acquire images through the videoinput() function. You might be able to find a replacement function on the File Exchange which can do this, but I am somewhat doubtful, as it would need to contain drivers for your particular video camera.
