I have the digital Elph and it has a view mode but the heat buildup would destroy the camera if they supplied a webcam option. So that is why they don't do that.
To get the cameras smaller they forego 24x7 operation so a good small camera will unlikely be a webcam.
Why this need?
i know of the capabilities of certain video cameras doubling as webcams, but is this feature available on any digital cameras out there? specifically, canon digital ixus i? digital elph?
thanks for your help,
