Import Statement: import QtMultimedia 5.6


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.

    imageProcessing {
        whiteBalanceMode: Camera.WhiteBalanceTungsten
        contrast: 0.66
        saturation: -0.5
