Using the Luminance Lookup Table to Get 8 Bit Output

As mentioned above, when the camera is set for a 12 bit pixel data format, the lookup table can be

used to perform a 12 bit to 12 bit substitution. The lookup table can also be used in 12 bit to 8 bit

fashion. To use the table in 12 bit to 8 bit fashion, you enter 12 bit substitution values into the table

and enable the table as you normally would. But instead of setting the camera for a 12 bit pixel data

format, you set the camera for an 8 bit format (such as Mono 8). In this situation, the camera will

first use the values in the table to do a 12 bit to 12 bit substitution. It will then truncate the lowest 4

bits of the substitute value and will transmit the remaining 8 highest bits.
