Black Level#

Black Level 相机功能允许您更改图像的整体亮度。调整相机的黑电平会导致相机输出的像素灰度值发生偏移。

例如,您可以将图像中每个像素的灰度值增加 3。

该功能的使用#

调整 Black Level#

信息

  • Basler 建议您在使用任何色彩增强功能之前将黑电平设置为 0,例如,Balance WhiteColor TransformationGamma。应用色彩增强后,您可以根据需要更改黑电平。但是,增加黑电平会降低颜色精确度。

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.

Types of Black Level Adjustment#

On racer 2 L camera models, the BlackLevelSelector parameter is available. This parameter allows you to choose between two types of black level adjustment. You can also perform both types of adjustment at the same time.

To configure black level adjustment:

  1. 设置 BlackLevelSelector 参数设置为以下值:
    • All: The black level value is applied universally.
    • SensorAll: The black level value is applied to the sensor.
      You can both increase and decrease the black level, which can be useful, e.g., if you want to set bright pixel values in the dark field to zero.
  2. Specify the desired black level.
  3. Optional: If you want to perform both types of black level adjustment, set the BlackLevelSelector parameter to the other value and repeat step 2.

Specifying a black level value of 0 effectively disables the respective adjustment.

信息

If you're using the DSNU correction of the Shading Correction feature, you have to create the shading correction set for DSNU correction again after you have adjusted the sensor black level.

Black Level 补偿#

暗电流可能会对图像质量产生负面影响。某些成像传感器可以通过自动调整黑电平来对此进行补偿。

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 to Off resets all internal correction values used for black level compensation.
