Detailed Description
CameraImageProcessing provides control over post-processing done by the camera middleware, including white balance adjustments, contrast, saturation, sharpening, and denoising
It should not be constructed separately, instead the imageProcessing property of a Camera should be used.
Camera { id: camera imageProcessing { whiteBalanceMode: Camera.WhiteBalanceTungsten contrast: 0.66 saturation: -0.5 } }
