The advantage of the luminance lookup table feature is that it lets a user customize the response
curve of the camera. The graphs below represent the contents of two typical lookup tables. The first
graph is for a lookup table where the values are arranged so that the output of the camera increases
linearly as the actual sensor output increases. The second graph is for a lookup table where the
values are arranged so that the camera output increases quickly as the actual sensor output moves
from 0 through 2048 and increases gradually as the actual sensor output moves from 2049 through
4096.

Note
There is only one lookup table. When the lookup table is enabled on color
cameras, the single table is used for red, green, and blue pixel values.
When a color camera is set for a YUV pixel data output format and the lookup
table is enabled, the lookup table is applied to the actual red, green, and blue
pixel values output from the sensor before the conversion from RGB to YUV is
performed.
