Hardware video adjustments
Many devices support video adjustments that you can use to improve the video quality.
For instance, you can use Video_CaptureDevice_VideoAdjust_GetRanges to get the current level of brightness, available adjustment ranges and the pitch.
| Delphi | VideoCapture1.Video_CaptureDevice_VideoAdjust_GetRanges(adj_Brightness, min, max, step, default, auto); |
| C++/C# | VideoCapture1.Video_CaptureDevice_VideoAdjust_GetRanges(VisioForge_Video_Capture_3. TxVFVideoCapAdjust.adj_Brightness, out min, out max, out step, out default_value, out auto); |
And with Video_CaptureDevice_VideoAdjust_SetValue, you can set the necessary level.
| Delphi | VideoCapture1.Video_CaptureDevice_VideoAdjust_SetValue(adj_Brightness, tbAdjBrightness.Position, cbAdjBrightnessAuto.Checked); |
| C++/C# | VideoCapture1.Video_CaptureDevice_VideoAdjust_SetValue(VisioForge_Video_Capture_3. TxVFVideoCapAdjust.adj_Brightness, tbAdjBrightness.Value, cbAdjBrightnessAuto.Checked); |
