Figure 2: Piece-wise linear signal
1.18.5.2.2.1 Description
Exposure ratios can be controlled by the program. Two rations are used: R1 = T1/T2 and R2 = T2/T3.
Increasing R1 and R2 will increase the dynamic range of the sensor at the cost of lower signal-to-noise ratio (and
vice versa).

• "HDREnable":
