Delphi and C# (ActiveX) sample code
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
VideoCapture1.Video_CaptureDevice_VideoAdjust_GetRanges(adj_Brightness, min, max, step, default, auto);
VideoCapture1.Video_CaptureDevice_VideoAdjust_GetRanges( VisioForge_Video_Capture_3.TxVFVideoCapAdjust.adj_Brightness, out min, out max, out step, out default_value, out auto);
VideoCapture1.Video_CaptureDevice_VideoAdjust_SetValue( adj_Brightness, tbAdjBrightness.Position, cbAdjBrightnessAuto.Checked);
VideoCapture1.Video_CaptureDevice_VideoAdjust_SetValue( VisioForge_Video_Capture_3.TxVFVideoCapAdjust.adj_Brightness, tbAdjBrightness.Value, cbAdjBrightnessAuto.Checked);
