USB camera image to dark
 

hey buddies... I have an interesting problem with Chicony webcam... My laptop is Satellite A205-s4707...

My webcam is working but it is very dark... I start my cam and I can see myself but after a few seconds it gets dark...

I change the brightness but again it shows me and again it gets dark... My OS is Pardus 2008.2... I cannot fix it.. Could you tell me how to do that..
