Color cameras
Setting LUT = OFF effectively makes full use of the 14 bit by bypassing the LUT circuitry; set-
ting LUT = ON means that the most significant 12 bit of the 14 bit are used and further down
converted to 10 bit. For cameras with 12-bit ADC: the most significant 10 bit of the 12 bit are
used.
