3.17 Look-Up Tables

The flat field corrections FPN and PRNU assume a linear response to the amount of
light by the sensor, output node, analog amplifier, and analog to digital converter. To
correct any non-linearity in this system of components a Look-Up Table (LUT) has
been implemented in the FPGA for each tap immediately after the ADC. The LUT adds
a signed value (-256 to +255) indexed by the 10 MSB of the input value.
