The advantage of the lookup table feature is that it allows the user to 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 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 sensor output moves
from 0 through 2048 and increases gradually as the sensor output moves from 2049 through
4096.

The lookup table smart feature does not add information to the image data stream
and can be accessed even when the extended data stream feature (see Section
6.7.1) is disabled.
The gain and offset functions remain active when the lookup table is used. Gain and
offset are applied to the pixel values reported from the sensor before the pixel values
are processed with the lookup table.
The lookup table feature will work when the camera is set for any valid video format.
When you enable the lookup table feature, a default lookup table is automatically
loaded into the camera (see Section 6.7.9 for more information about the default ta-
ble). If you want use your own customized lookup table you must:
1. Use the look table feature Control and Status Register (CSR) to enable the
lookup table feature.
2. Write the values for your customized lookup table to the CSR.
