# Code sample - Hardware video adjustments

Delphi and C# (ActiveX) sample code

Many devices support video adjustments that you can use to improve 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);
