Figure 1-7 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 511 and increases gradually as the sensor output moves from 512
through 1023.

The EZView utility offers a
used to easily load a file containing a customized lookup table into the
camera. The file must be plain text and must be formatted correctly.
The file must have 1024 lines with each line
containing two comma-separated values.
The first value on each line represents a 10
bit pixel reading from the sensor and the
second value represents the corresponding
8bit output that will be transmitted from the
camera.
The sample below shows part of a typical
text file for a lookup table. Assuming that you
have enabled the lookup table feature on
your camera and used the upload button to
load a file similar to the sample into the
camera:
The sensor reports that a pixel has a value of
1, the camera will output a value of 0.
The sensor report that a pixel has a value of
6, the camera will output a value of 1.
The sensor report that a pixel has a value of
1019, the camera will output a value of 254.
