Black Level (NI 177xC Smart Cameras)
The black level specifies the image brightness. Set the black level to the
pixel value which corresponds to true black. If the black level is innacurate,
near-black pixels may be displayed as black or black objects may appear
gray in the output image.

Look-Up Table
A look-up table (LUT) transformation maps pixel values in the source
image into other values in the transformed image. For example, you can use
a LUT transformation to improve the contrast and brightness of an image.
Note
NI 177xC Smart Cameras allow you to define a LUT for each color plane in the RGB
color space.
To enable a LUT in MAX, use the
LUT Controls
on the
Camera
Attributes
tab of the device configuration page.
