Configuring the Camera 47
TM-6740GE Series
5.4 LUT (Look Up Table)
The camera’s LUT is used for dynamic range control when the camera is in 8-bit output mode (Mono8 or
BayerGR8). This allows for the full utilization of the image sensor’s 10-bit output as it is mapped to the 8-bit
output.
Figure 17. LookUp Table
LUTMode: controls which LUT table to use. There are 2 predefined tables and 1 user configurable table.
Available options:
−
Linear: a linear mapping
−
Gamma45: also known as Gamma 0.45.
−
Knee: you can specify the curve by controlling two points.
KneeX1: controls the X value of first Knee point.
KneeY1: controls the Y value of first Knee point.
KneeX2: controls the X value of second Knee point. This value must be greater than KneeX1.
KneeY2: controls the Y value of second Knee point.
KneeSet: after you have changed the values of the knee points click KneeSet to apply the setting. The camera
will take a few seconds to calculate the LUT table. If image acquisition is taking place the image will black out
for about 1 second.
LUTInversion: invert the current LUT table. This creates the negative of image.
