8.3.2 LUT Index
This represents the “starting” or “input” pixel value to be modified by the Lookup Table. The
SP-5000-GE2 has a 256-point Lookup Table, meaning the index points are treated like an 8-bit
image with 0 representing a full black pixel and 255 representing a full white pixel. The index
points are automatically scaled to fit the internal pixel format of the camera. This is common
for all output configurations.
8.3.3 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 or 10-bit).
Note: linear interpolation is used if needed to calculate LUT values between index points. In the
color mode, the LUT function works the same regardless of the color of the pixel.

8.4. Gamma
This command is used to set gamma between gamma 0.45 and gamma 1.0 (OFF) in 16 steps.
The gamma value is an approximate value.

8.4.1 Linear and Dark Compression
SP-5000-CXP2 has a dark compression circuit to improve the signal-to-noise ratio in the dark portion
of the image.
