Detailed DescriptionThe QCameraImageProcessingControl class provides an abstract class for controlling image processing parameters, like white balance, contrast, saturation, sharpening and denoising. The interface name of QCameraImageProcessingControl is com.nokia.Qt.QCameraImageProcessingControl/1.0 as defined in QCameraImageProcessingControl_iid. See also QMediaService::requestControl() and QCamera. Member Type Documentation
|
| Constant | Value | Description |
|---|---|---|
| QCameraImageProcessingControl::Contrast | 0 | Image contrast. |
| QCameraImageProcessingControl::Saturation | 1 | Image saturation. |
| QCameraImageProcessingControl::Brightness | 2 | Image brightness. |
| QCameraImageProcessingControl::Sharpening | 3 | Amount of sharpening applied. |
| QCameraImageProcessingControl::Denoising | 4 | Amount of denoising applied. |
| QCameraImageProcessingControl::ColorTemperature | 5 | Color temperature in K. This value is used when the manual white balance mode is selected. |
| QCameraImageProcessingControl::ExtendedParameter | 1000 | The base value for platform specific extended parameters. |
Member Function Documentation
QCameraImageProcessingControl::QCameraImageProcessingControl ( QObject * parent = 0 ) [protected]
Constructs an image processing control object with parent.
QCameraImageProcessingControl::~QCameraImageProcessingControl ()
Destruct the image processing control object.
bool QCameraImageProcessingControl::isProcessingParameterSupported ( ProcessingParameter parameter ) const [pure virtual]
Returns true if the camera supports adjusting image processing parameter.
Usually the the supported settings is static, but some parameter may not be available depending on other camera settings, like presets. In such case the currently supported parameters should be returned.
bool QCameraImageProcessingControl::isWhiteBalanceModeSupported ( QCameraImageProcessing::WhiteBalanceMode mode ) const [pure virtual]
Returns true if the white balance mode is supported. The backend should support at least QCameraImageProcessing::WhiteBalanceAuto mode.
QVariant QCameraImageProcessingControl::processingParameter ( ProcessingParameter parameter ) const [pure virtual]
Returns the image processing parameter value.
See also setProcessingParameter().
void QCameraImageProcessingControl::setProcessingParameter ( ProcessingParameter parameter, QVariant value ) [pure virtual]
Sets the image processing parameter value. Passing the null or invalid QVariant value allows backend to choose the suitable parameter value.
The valid values range depends on the parameter type, for contrast, saturation and brightness value should be between -100 and 100, the default is 0,
For sharpening and denoising the range is 0..100, 0 for sharpening or denoising disabled and 100 for maximum sharpening/denoising applied.
See also processingParameter().
void QCameraImageProcessingControl::setWhiteBalanceMode ( QCameraImageProcessing::WhiteBalanceMode mode ) [pure virtual]
Set the white balance mode to mode
See also whiteBalanceMode().
QCameraImageProcessing::WhiteBalanceMode QCameraImageProcessingControl::whiteBalanceMode () const [pure virtual]
Return the white balance mode being used.
See also setWhiteBalanceMode().
