Operation
3.6 Programmable Look-Up Table (LUT) and Knee Control
The TM-1402 has a built-in LUT (look-up table) for dynamic range control.
At a specific gain setting, the offset (minimum level.... dark point) and A/D reference top voltage
(maximum level... saturation point) are set to 10-bit A/D input so that the full dynamic range of the
CCD is utilized at 10-bit references as the input and the LUT output is converted into 8-bit to adjust the
gamma correction.
The 10-bit input is segmented into two or more regions by the knee-point settings as variable gamma
selection.
