Black Level#
For example, you can increase the gray value of each pixel in the image by 3.
Using the Feature#
Adjusting the Black Level#
Info
- Basler recommends setting the black level to 0 before using any of the color enhancement features, e.g., Balance White, Color Transformation, or Gamma. After the color enhancements have been applied, you can change the black level as desired. However, increasing the black level will decrease the color accuracy.
To adjust the black level, enter a value for the BlackLevel parameter.
The change in the gray value resulting from the BlackLevel parameter value depends on the camera model.
Black Level Compensation#
Dark current can have a negative impact on image quality. Some image sensors can compensate for this by automatically adjusting the black level.
On some camera models, you can manually enable or disable this automatic adjustment using the BslBlackLevelCompensationMode parameter.
To do so, set the BslBlackLevelCompensationMode parameter to one of the following values:
Sensor: Black level compensation is performed by the image sensor. The sensor tries to compensate for thermally generated voltages that would affect the signals (dark current).Off: Black level compensation is disabled. This is useful, e.g., for quantitative analysis of weak light signals or if you need raw image data without dark current correction.
Setting the compensation mode toOffresets all internal correction values used for black level compensation.

On daA1280-54um/uc, daA1280-54lm/uc, and puA1280-54um/uc cameras, the black level settings are applied to the pixel data after the gain settings. On all other dart and pulse cameras, the black level settings are applied before the gain settings.
Sample Code#
ace Classic/U/L GigE Cameras#
/* 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 black level to 32 */
errRes = PylonDeviceSetFloatFeature(hdev, "BlackLevelRaw", 32.0);
CHECK(errRes);
/* Disable black level compensation */
/* Note: Available on selected camera models only */
errRes = PylonDeviceFeatureFromString(hdev, "BslBlackLevelCompensationMode", "Off");
CHECK(errRes);
Other Cameras#
/* 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 black level to 32 */
errRes = PylonDeviceSetFloatFeature(hdev, "BlackLevel", 32.0);
CHECK(errRes);
/* Disable black level compensation */
/* Note: Available on selected camera models only */
errRes = PylonDeviceFeatureFromString(hdev, "BslBlackLevelCompensationMode", "Off");
CHECK(errRes);
You can also use the pylon Viewer to easily set the parameters.
