Fig. 61: Lookup Table with Values Mapped for Higher Camera Output at Low Sensor Readings
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.
Changing the Values in the Luminance Lookup Table and Enabling the Table
You can change the values in the luminance lookup table (LUT) and enable the use of the lookup
table by doing the following:
1. Use the LUT Selector to select a lookup table. (Currently there is only one lookup table avail-
able, i.e., the "luminance" lookup table described above.)
2. Use the LUT Index parameter to select an index number.
3. Use the LUT Value parameter to enter the substitute value that will be stored at the index
number that you selected in step 2.
4. Repeat steps 2 and 3 to enter other substitute values into the table as desired.
5. Use the LUT Enable parameter to enable the table.
