Feature Request - brightness/contrast

ajpalm · Post by **ajpalm** » Fri Sep 10, 2004 4:42 am

I noticed I could edit the brightness contrast while viewing a camera, but I also noticed this effected all cameras.

Is it possiable that that each camera can have its own settings? As I find due to different lighting levels I need to ‘tweak’ the picture on each camera a bit. Ie one in full sun and one under a carport. The camera adjusts itself I know, but a slightly better picture can be gotten by tweaking these provided settings, one setting does work for all cameras though.

Thanks for listening and Love your work

That depends on the type of video input card you have. The cheaper ones (mostly) tend to share one video digitising chip between multiple cameras, and the contrast/brightness settings are applied to the digitising chip, so change on and you change them all...

Well this would be the case then. Its a one chip that services 4 camera input card.

Then maybe the setting should be split into two then. One for the card that effects all cameras and one per camera input.

A slight brightness/contrast adjustment on each picture isn't much more load compared to whats already happening to the picture.

I suspect you would find that the response would be so slow that by the time an brightness change had taken effect the capture would have switched onto the next camera and you would probably not get the effect you desired. It might be worth experimenting though, there is a patch about to make these setting persistent somewhere.
