Thanks for reply!

I agree that keeping web-cam always on is not a good idea. Actually it may
prevent some real applications, such as Skype to use web-cam. I think about
making a shots every minute for example. That partially solves the problem
with power.

&gt; Today a lot of laptops have integrated web-camera, but don&#39;t have any<br>

I would be your best contact point for it probably. I admit I am not<br>
really fond of the idea - keeping the webcam on and busy all of the<br>
time to make it act like an (inaccurate) light sensor is quite a waste<br>
of resources to me, and most laptop users would rather live without<br>
auto-adjustment than with 1 hour less of battery. A proposal about<br>
