LUT (Lookup Table)

This function can be used to convert the input to the desired output characteristics. The Lookup Table
(LUT) has 32 points for setup on this camera. The output level can be created by multiplying the gain
data by the input level.
JAI LUT Mode (Analog Control)
Can be selected from OFF, Gamma or LUT table.
LUT Index (LUT Control)
This represents the "starting" or "input" pixel value to be modified by the Lookup Table. This camera
has a 32-point Lookup Table. Thus, on this camera, 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.
LUT Value (LUT Control)
This is the "adjusted" or "output" pixel value for a given LUT index. It has a range of 0 to 4095 (12 bits)
and is automatically scaled to the bit depth of the current output mode (8-bit, 10-bit, or 12-bit). Linear
interpolation is used to calculate LUT values between index points.
Note: *The LUT must have a positive slope, i.e., the value for each index must be greater than the
previous index. If the value for an index is set ≤ one or more previous indexes, those indexes will
be automatically adjusted to maintain a positive slope.
