analog digital gain gain
Introduction
Black level defines the brightness in the darkest part of the image.
Possible black level settings are values between 0 and 255. If the set ‐
ting is correct, the sensor will deliver the pixel value 0 for a com ‐
pletely black image. If it is too high, the sensor will deliver a pixel
value greater than 0 for black which means a shade of gray. If the
value is too small, the sensor will deliver a pixel value of 0 for gray
shades.
Analog gain is used to increase the brightness of an image. The avail ‐
able range depends on the camera connected. If you increase the
analog gain, all pixel values of the image will be increased which
means, the whole image becomes brighter. Unfortunately, noise will
increase too because the analog gain becomes effective prior to the
ADC conversion executed by the sensor.
BlackLevel
The black level value defines the brightness in the darkest part of an
image. An optimal setting means, the pixel value 0 is delivered for a
completely black image. If it is too high, it will deliver a pixel value
greater than 0 (which is reserved for a shade of gray). It it is too small,
it will deliver a pixel value of 0 for a shade of gray.
