Fig. 58: Lookup Table with Values Mapped for Higher Camera Output at Low Sensor Readings
Using the Luminance Lookup Table to Get 10 Bit or 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 10 bit
or 12 bit to 8 bit fashion.
To use the table in 12 bit to 10 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 a 10 bit format (such as Mono 10). 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 least
significant 2 bits of the substitute value and will transmit the remaining 10 most significant bits.
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 least
significant 4 bits of the substitute value and will transmit the remaining 8 most significant bits.
