Lookup Table (Lut) - JAI SW-4000T-10GE User Manual

Lookup Table（LUT）
The LUT function is used to generate a non-linear mapping between signal values captured on
the sensor and those that are output from the camera.
You can specify the output curve using 257 setting points (indexes).
■ To use the LUT function
Configure the settings as follows.
Item selectable range
LUTMode LUT
LUTSelector* Red, Green, Blue
LUTIndex 0 ～ 256
LUTValue 0 ～ 4095
■ LUT Value
LUT values range from 0 at the lowest to 4095 at the highest. Linear interpolation is used to
calculate LUT values between the index points.

Use LUT.
Select the LUT channel to control.
Select the LUT index to configure. Indexes represent the
possible pixel values captured on the sensor, from the
lowest value (Index 0) to the highest (Index 256). For
example, Index 0 represents a full black pixel and Index
256 represents a full white pixel.
Set the LUT output value for the selected index.

Values between points are determined
using the linear interpolation values of
data to the left and right.
