    Hi,

    I use QCamera class to get images.

    But the resolution is 640480 !
    My camera resolution is 2592
    1944

    I tried this:

    @
    camera = new QCamera(myCam);

    imageCapture = new QCameraImageCapture(camera);
    
    QImageEncoderSettings imageSettings;
    imageSettings.setResolution(2592,1944);
    imageCapture->setEncodingSettings(imageSettings);
    
    camera->setViewfinder(ui->viewfinder);
    
    connect(imageCapture, SIGNAL(imageCaptured(int,QImage)), this, SLOT(processCapturedImage(int,QImage)));
    
    camera->setCaptureMode(QCamera::CaptureStillImage);
    camera->start();
    

    @

    But it still 640*480.

    Anyone have already solved this problem? thx

      Hi,

      You should also add which version of Qt and OS you are using.

      Did you check the value of available resolutions with supportedResolutions ?

        Os: Windows 7 & 8.1
        Qt : 3.0.0, Fram : 5.2.0, Compiler : Mingw 4.8
        App in 32 bit

        Yes I tried supportedResolutions or supportedFlash (the flash doesn't work too)... but ALL results of this function are "VOID":

        @qDebug() << imageCapture->supportedResolutions();@

        Result :
        ()
