9.3.2
LUT selector
In the GO-5000C-USB, the selection of R, G or B is displayed. Select one to adjust. In the
GO-5000M-USB, this is not displayed.
9.3.3
LUT Index
This represents the "starting" or "input" pixel value to be modified by the Lookup Table. The
GO-5000M-USB has a 32-point Lookup Table, meaning the index points are treated with 0
representing a full black pixel and 31 representing a full white pixel. In the GO-5000C-USB, a Look
up Table is 16 points instead of 32 points. The index points are automatically scaled to fit the
internal pixel format of the camera. This is common for all output configurations.
9.3.4
LUT value
This is the "adjusted" or "output" pixel value for a given LUT index. It has a range of 0 to 4095
(12-bit) and is automatically scaled to the bit depth of the current operating mode (8-bit, 10bit or
12-bit).
Note: linear interpolation is used if needed to calculate LUT values between index points. In the
color model, the LUT function works the same regardless of the color of the pixel.

9.4.
Gamma
This command is used to set gamma between gamma 0.45, gamma 0.6 and gamma 1.0 (OFF) in 3
steps.
The gamma value is an approximate value.
