The gain settings result in the following amplifications:
3.5.2 Setting Brightness
The camera’s brightness is determined by the setting in the Value field of the Brightness control
register (see page 4-20). The brightness setting can be programmed on a decimal scale that
ranges from 0 to 255, (0x000 to 0x0FF).
If the camera is operating in any output mode other than Mono 16, a brightness setting of around
8 (decimal) will result in an offset of 0 in the digital values output for the pixels. (Due to tolerances
in the electronic components in your camera, you may find that the default brightness is set to a
slightly different setting.) An increase of 16 (decimal) in the brightness setting will result in a
positive offset of 1 in the digital values output for the pixels. For example, a brightness setting of
around 24 (8 + 16, decimal) would be required to reach a positive offset of 1. A brightness setting
of around 40 (8 + 16 + 16, decimal) would be required to reach a positive offset of 2, and so on.
If the camera is set for Mono 16 output, a brightness setting of around 0 (decimal) will result in an
offset of 0 in the digital values output for the pixels. An increase of 1 (decimal) in the brightness
setting will result in a positive offset of 1 in the digital values output for the pixels.
