Does chnaging v4l2 default settings improves usb camera performance? : I'm have USB ELP camera. I'm using v4l2 driver to capture images from that USB camera. I've found that we can change v4l2 default parameters like brightness, contrast, gamma, exposure, resolution. Can we able to increase the speed of camera access time so that it can captures images at less time by changing these parameters to optimum values ?

Thanks for advice.
