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. The camera will calculate the table base on
the Knee values below.
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. It is recommended to stop image acquisition during this
time.
LUTInversion:
invert the current LUT table. This creates the negative of image.
