LUT (Lookup Table)

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 256 setting
points (indexes).

■ To use the LUT function

Configure the settings as follows.
Item
JAI LUT Mode LUT
LUT Selector* R, G, B
LUT Index GO-2401M-PGE: 0 to 255
GO-2401C-PGE: 0 to 255
LUT Value 0 to 4095
* GO-2401C-PGE only
Note
For the GO-2401C-PGE, separate characteristic curves are configured for R, G, and B.

■ LUT values

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 255). For example,
Index 0 represents a full black pixel and Index 255
represents a full white pixel on the GO-2401M-PGE.
Set the LUT output value for the selected index.
