Problem with camera
-
I'm trying to get a camera properties e.g contrast, saturation. I'm having some problems using QCamera and QCameraImageProcessing. The fuction of isAvailable() always returns false.How would I control these properties
camera = new QCamera(cameraDevice); QCameraImageProcessing *imageProcessing = camera->imageProcessing(); qDebug()<<"isAvailable:"<<cameraProcessing->isAvailable(); if (imageProcessing->isAvailable()) { imageProcessing->setDenoisingLevel(-0.3); }

Hi,
Depending on your OS/backend you won't necessarily have access to all properties. What version of Qt are you running ? On which platform ?

IIRC, on Windows you have to use the DirectX backend to have the support for camera

Hi, if you need to do serious, advance image processing or some fun computer vision tricks, openCV3.0 may give you a hand(release on yesterday), this way you do not need to rely on the back end of the OS to help you denoise, white balance, inpainting, face recognition, text recognition and so on.
