Function imnoise() in Matlab

Why is the mean for imnoise() limited to [0,1]? Is there a way to extend it?

if you are just trying to add gaussian noise to yor image, you could do it 'manually'

>> image = image + mean*randn( size(mage) );

According to the documentation, all the numerical parameters for IMNOISE are normalized by the image intensity. 1 indicates the maximum intensity for the image. It isn't possible to set a pixel to a value outside that range.
