| 61 |     \brief The QCameraImageProcessingControl class provides an abstract class | 
| 62 |     for controlling image processing parameters, like white balance, | 
| 63 |     contrast, saturation, sharpening and denoising. | 
| 64 |  | 
| 65 |     The interface name of QCameraImageProcessingControl is \c org.qt-project.qt.cameraimageprocessingcontrol/5.0 as | 
| 66 |     defined in QCameraImageProcessingControl_iid. | 
| 67 |  | 
| 68 |     Camera service may choose the parameters of image processing pipeline depending | 
| 69 |     on sensor properties camera settings and capture parameters. | 
| 70 |  | 
| 71 |     This control allows to modify some parameters of image processing pipeline | 
| 72 |     to achieve desired results. | 
| 73 |  | 
| 74 |     Parameters with the "Adjustment" suffix, like ContrastAdjustment, SaturationAdjustment etc | 
| 75 |     allows to adjust the parameter values, selected by camera engine, | 
| 76 |     while parameters like Contrast and Saturation overwrites them. | 
| 77 |  | 
| 78 |     For example setting the SharpeningAdjustment parameter to -0.1 | 
| 79 |     slightly reduces the amount of sharpening applied, | 
| 80 |     while settings the Sharpening parameter to 0 disables sharpening at all. |
