Gain#

The Gain camera feature allows you to increase the brightness of the images output by the camera.

Increasing the gain increases all pixel values of the image.

To adjust the gain value automatically, use the Gain Auto feature.

Using the Feature#

Configuring Gain Settings#

  1. Set the GainAuto parameter to Off.
  2. If the GainSelector parameter is available, set it to one of the following values:
    • AnalogAll: Selects the analog gain control.
    • DigitalAll: Selects the digital gain control.
  3. Set the Gain parameter to the required value.
    The minimum and maximum parameter values vary depending on the camera model, the pixel format chosen, and the Binning settings.

"Raw" and Absolute Gain Values#

On some camera models, the gain must be entered as a "raw" value on an integer scale. The camera needs the raw value for its internal processing mechanism. The raw value, however, isn't the same as the actual gain value, which is expressed in decibels (dB).

In the camera-specific Gain Properties table, you can find a formula to calculate the absolute gain (in dB) from the raw gain value.

Analog and Digital Gain#

Analog gain is applied before the signal from the camera sensor is converted into digital values. Digital gain is applied after the conversion, i.e., it is basically a multiplication of the digitized values.

Depending on your camera model, the mechanisms to control analog and digital gain can vary:

  • For some cameras, gain control is analog up to and including a certain threshold. Above the threshold, gain control is digital.
  • For some cameras, gain control is entirely digital.
  • For some cameras, you can use the GainSelector parameter to manually switch between analog and digital gain.

  1. Analog gain / digital gain.

Sample Code#

ace Classic/U/L GigE Cameras#
// Set the "raw" gain value to 400
// If you want to know the resulting gain in dB, use the formula given in this topic
camera.GainRaw.SetValue(400);
INodeMap& nodemap = camera.GetNodeMap();
// Set the "raw" gain value to 400
// If you want to know the resulting gain in dB, use the formula given in this topic
CIntegerParameter(nodemap, "GainRaw").SetValue(400);
// Set the "raw" gain value to 400
// If you want to know the resulting gain in dB, use the formula given in this topic
camera.Parameters[PLCamera.GainRaw].SetValue(400);
/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Set the "raw" gain value to 400 */
/* If you want to know the resulting gain in dB, use the formula given in this topic */
errRes = PylonDeviceSetIntegerFeature(hdev, "GainRaw", 400);
CHECK(errRes);
Other Cameras#
// Set the gain to 4.2 dB
camera.Gain.SetValue(4.2);
INodeMap& nodemap = camera.GetNodeMap();
// Set the gain to 4.2 dB
CFloatParameter(nodemap, "Gain").SetValue(4.2);
// Set the gain to 4.2 dB
camera.Parameters[PLCamera.Gain].SetValue(4.2);
/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Set the gain to 4.2 dB */
errRes = PylonDeviceSetFloatFeature(hdev, "Gain", 4.2);
CHECK(errRes);

You can also use the pylon Viewer to easily set the parameters.
