GO-5000M-PGE / GO-5000C-PGE

9.3. LUT
This function can be used to convert the input to the desired output characteristics.
The Look-Up Table (LUT) has 32 points for setup in the GO-5000M-PGE and 16 points for each R, G
and B in GO-5000C-PGE. The output level can be created by multiplying the gain data by the input
level.
9.3.1 LUT Enable
Can be selected from OFF, Gamma or LUT table.
9.3.2 LUT Index
This represents the “starting” or “input” pixel value to be modified by the Lookup Table. The
GO-5000M-PGE has a 32-point Lookup Table. Thus, in the GO-5000M-PGE, an index value of 0
represents a full black pixel and a value of 31 represents a full white pixel. The index point values
are automatically scaled to fit the internal pixel format of the camera. This is common for all
output configurations. In the GO-5000C-PGE, it is a 16-point Lookup Table.
9.3.3 LUT value
This is the “adjusted” or “output” pixel value for a given LUT index. It has a range of 0 to 4095 and
is automatically scaled to the bit depth of the current operating mode (8-bit, 10-bit, or 12-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.
Output Data = Video IN x LUT data

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