2013-10-21 06:16:13 -0600	commented question	Enable Auto Exposure using code I don't know if this will help you but I've had some success by setting the exposure value then calling QueryFrame twice and set the exposure value again. The next QueryFrame after that might come out with the expected value. This might not help with your particular camera but it seemed to work with mine and it doesn't help with the original question.

2013-10-07 11:19:53 -0600	asked a question	Enable Auto Exposure using code I've had trouble with this before hen trying to disable the Auto Exposure on my webcam, I managed to do it by setting the CV_CAP_PROP_EXPOSURE value which automatically disabled the Auto Exposure. I'd now like to be able to turn it back on for a few seconds and then disable it again but any value I set for CV_CAP_PROP_AUTO_EXPOSURE doesn't seem to take yet I can open a dialog with CV_CAP_PROP_SETTINGS and enable it from within that popup. There must be a way to enable this through code if it's possible through the Settings dialog. I thank you for your time and any help you can offer.

2013-08-29 07:16:49 -0600	commented answer	cvSetCaptureProperty where are the settings? Solved Thanks a bunch I'll see if I can't get anything out of it from OpenCV but if not I'll see if there are any other API's which could be used to do this instead, thanks again for your help.
2013-08-29 05:44:54 -0600	commented question	cvSetCaptureProperty where are the settings? Solved If anyone else gets this problem I've been able to use Skype to reset the webcam properties. Now if I could get a way to turn the auto white balance and auto exposure off using OpenCV throught code, any ideas?
2013-08-29 04:16:21 -0600	commented question	cvSetCaptureProperty where are the settings? Solved Thanks for your response, I thought it might be stored on the device. Sadly the software that comes with the camera doesn't install and there isn't a visible hard reset button on the device. It's definitely on the device as I tried another unit and it works as expected. I will try to get in contact with the manufacturers, thanks for your help. It's not good that you can brick a piece of hardware with code and not be able to restore it.
2013-08-28 11:44:08 -0600	asked a question	cvSetCaptureProperty where are the settings? Solved I was looking to disable the auto balancing on my webcam but somehow I've set make the picture become permanently very highly exposed. I've been trying to reset the settings back to default but to no avail. The problem continued after I re-installed the driver and restarted the computer. Where are the settings changed by cvSetCaptureProperty stored? Perhaps I can delete them and start fresh. Thanks for any help provided.
