Yes i did previously i was using opencv 2.1 now this program i used with opencv 2.3 but same result. and i have right now USB camera,because of that it may not showing values 2marrow i will try with my inbuilt cam then i will inform you and thanks a lot to reply me.

The only other thing to try might be to get the latest OpenCV, or build a copy from the OpenCV subversion source, or maybe try a different webcam (like a USB one instead of a built-in one).

Thanks to reply me i tried as you told i put these all statement in main loop and wait for 5 min.
but still same result as 0. but when i put CV_CAP_ANY at place of CV_CAP_V4L2 then i got only frame width and height and all the remaining values i am getting same as previous one result means 0.

cout << "Image brightness: " << cvGetCaptureProperty(pCapture, CV_CAP_PROP_BRIGHTNESS) << endl;
cout << "Image contrast: " << cvGetCaptureProperty(pCapture, CV_CAP_PROP_CONTRAST) << endl;
cout << "Image saturation: " << cvGetCaptureProperty(pCapture, CV_CAP_PROP_SATURATION) << endl;
cout << "Image hue: " << cvGetCaptureProperty(pCapture, CV_CAP_PROP_HUE) << endl;

As I don’t know whether OpenCV gets these properties from the hardware or calculates them itself, another possibility is that it’s a camera-chipset related issue, and those properties simply aren’t available from your webcam’s hardware.

Hope this helps.

As i try your code its very nice, but there in my code i am trying to get camera Brightness,and Contrast as you are trying to print, but i am getting all the 0 value. how you are getting these values?
