How to set webcam parameters programatically on Microsoft Lifecam Cinema (e.g. switch off autofocus)

原文 2010-06-15 12:33:11 7 2 windows/ webcam

The Microsoft Lifecam Cinema software has several options to control focusing, exposure and so on. I need to control these programatically for a machine vision project. How can this be achieved?

MATLAB toolbox for image acquisition allow access to the full functionality of the LifeCam. Eg focus. However the provided driver has a problem, which Microsoft refuses to deal professional with - they claim that it is MATLAB that has a problem. So at the moment I cannot control brightness and exposure, two parameters that should be accessible.

I ran into this same problem on a photo booth kiosk I built. To get around it, I created a simple command line utility to set these preferences and allow for reapplying them at startup.
