Is it possible to disable webcam led while capturing an image on Windows?

A videocapture object has set and get functions. On android you could just do Videocapture.set(CV_CAP_PROP_ANDROID_FLASH_MODE, CV_CAP_ANDROID_FLASH_MODE_OFF).

The only thing that looks close to something like led light is CV_CAP_PROP_BACKLIGHT. So try to do Videocapture.set(CV_CAP_PROP_BACKLIGHT, 0)

I don't think, that is possibly. That is on hardware level or at best on driver level.

most win webcam drivers come with a properties page, that you can call e.g from vlc, media player, etc, - even (with a bit of luck) from opencv:

VideoCapture cap(0);
cap.set(CAP_PROP_SETTINGS,1);

the settings will be persistant, but you'll have to remember, which usb port you plugged it into !
