I'm going to calibrate GUI elements for all video settings. See picture.
Can I get the maximums and minimums of the parameters of the USB-camera with OpenCV?
One can easily set and get the camera parameters: Setting Camera Parameters in OpenCV/Python
But the different cameras can have not equal ranges of some parameter so you cannot hard code it. For example the Genius Slim 320 USB-camera has the brightness range 0...255, but an another USB-camera has the brightness range -64...+64. Is it possible to get the maxima and minima of the USB-camera parameters (such as a brightness, contrast and so on) by means of OpenCV itself?
