C2 Output LUTs<br />
The output LUTs allow you to apply custom LUTs to the video stream. The output LUTs<br />
are a set of general-purpose lookup tables that are applied to the digitized camera data<br />
immediately before the data exits the camera. With the output LUTs, you can apply<br />
image characterizations such as brightness, contrast, or apply a gamma look-up table. The<br />
output LUTs differ from the input LUTs in that a single set of table values is common to<br />
all output taps of the camera; there is no mechanism to handle the different taps<br />
independently.<br />
You can create a table to generate almost any camera output response desired. Linear<br />
functions such as y = mx + b or y = a1 * xˆ2 + a2 * x + a3 can be easily generated and<br />
loaded into the LUT using a scripted macro containing repeated calls to the set output<br />
LUT (sol) command. The following are examples of common applications of LUTs:<br />
Unity LUT (output = input)<br />
LUT = [0, 1, 2, 3… 1020, 1021, 1022, 1023]<br />
Gain of 2 (output = 2 * input) 1<br />
LUT = [0, 2, 4, 6… 1023, 1023, 1023, 1023]<br />
Offset of 2 (output = 2 * input + 2) 1<br />
LUT = [2, 3, 4, 5… 1022, 1023, 1023, 1023]<br />
Or any other desired mapping (e.g. output= 3 * output 2 + 1)<br />
LUT = [1, 4, 13, 28… 1023, 1023, 1023, 1023]<br />
Note: Values loaded into the LUT must be within the valid range for a 10-bit integer (0
