Re: Controlling Exposure on webcam

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

I have no idea what the Webcam application is. But it seems to do no
streaming. The camera has an autoexposure setting that needs some time
to kick in. So taking a single picture will do you no good if you did
not set the exposure to something reasonable before. Check the /proc
interface to control the camera. But note that in more recent
kernel-versions this was disabled due to a security problem.
