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);
And with Video_CaptureDevice_VideoAdjust_SetValue, you can set the necessary level.
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);
