8.2 Black Level
Adjusting the camera’s black level will result in an offset to the pixel values output by the camera.
Increasing the black level setting will result in a positive offset in the pixel values output for the
pixels. Decreasing the black level setting will result in a negative offset in the pixel values output for
the pixels.
For example, if the black level parameter value is increased by 1 the pixel value for each pixel is
increased by 1. If the black level parameter value is decreased by 1 the pixel value for each pixel
is decreased by 1.
8.2.1 Setting the Black Level
The black level can be adjusted by changing the value of the Black Level parameter.
The range of the allowed settings for the Black Level parameter value in [DN] varies by camera
model as shown in Table 31.
