As you wish:
1. In what kind of ideal world where we have working and documented
drivers for everything we could do what you said even remotely, and
most of all into userspace?
A "real" light sensor is typically just a CdS cell. CdS, Cadmium Sulfide,
reacts to light by changing its resistance. The circuit is very simple
(put it in series with a resistor to form a voltage divider, and read the
resultant voltage), and very cheap. That, of course, is why we'd use them

Sure ;-)
On my laptop, the webcam is covered by a bit of paper (not joking, some
of us are paranoid ;-)
But why not design and build a real ambient light sensor with a usb
interface and use th

Allow me, as an information engineer and a computer scientist, to
think you missed part of the picture :)
I don't want to challenge your argument of the power consumption of
the webcam even though

As an electrical engineer, I find this idea sound. With a low sampling
rate, such as 0.5 Hz (once every 2 seconds), the additional power draw
should be negligible. 1/60th Hz is far too slow to produce enough quality
for users to appreciate it. 0.5 Hz should be considered a minimum. While

I agree that keeping web-cam always on is not a good idea. Actually it may

making a shots every minute for example. That partially solves the problem
with power.

Hi!
I'm a student of Belarusian State University and I would like to
participate in GSoC 2012.
The idea for my project is to create an automatic brightness
adjustment mechanism using web-camera as light sensor.
Today a lot of laptops have integrated web-camera, but don't have any
light sensor. S
