Webcam. Brightness & Gamma Control




Hello

I am using a Ricoh Webcam with the driver r5u870.

The problem is that the image quality is poor, it is too dark, thus I
would like to brighten it.

I have tried to do it using v4l-conf, v4lctl, but I get a message like this:

"v4l brightness control not supported"

I am not sure I am asking in the right place, but I have been
"interneting" for a while on r5u870 and v4l and found nothing that
helps me.

How could I determine where the problem is? Where can I check the
logfile for v4l start up. That would help me check wether the problem
is from the webcam driver or from v4l.

Cheers
