Subtracting Background
Serial Command
Purpose:
Use the background subtract command after performing flat
field correction if you want to improve your image in a low
contrast scene. It is useful for systems that process 8 bit data
but want to take advantage of the camera’s 10 bit digital
processing chain. You should try to make your darkest pixel in
the scene equal to zero.
Syntax:
