Manual Gain Webcam

May 7, 2008 | 7:57 pm

Hey does anyone know of any webcams with a manual gain? (i.e. a camera you can set to not change in different lighting situations). Or, as an alternative, is there a way to achieve this in jitter?

Thanks,

Hi Nick.

I would reckon some of the more advanced webcams, like the new HD
Logitech ones, would allow for more tweaking in the setup page. I am
buying a few highend Logitechs soon, will let you know.

I’m not positive but I’m pretty sure the iSight can be set manually (at least for the models from two years ago). You have to do it through the software there aren’t any manual controls on the camera.

Unibrain Fire-I camera comes with software in which you can manually control gain, shutter speed and saturation amongst other things.

use an IIDC firewire camera, and you can then send it IIDC commands
from Jitter to control gain, exposure, etc manually. No need for
additional software. Look at the jit.qt.grab help file for info on
this. As people mentioned already, the iSight and Unibrain’s Fire-I
are both IIDC cameras. (However, in my experience things don’t work
well with multiple i-sights if you are going to want multiple
cameras). I am currently using IIDC firewire cameras made by The
Imaging Source and they are also good for manual jitter control.
