The dynamic range can be increased by dividing the integration (exposure time) in two or three phases (slopes), with different
maximum saturation levels. The CB200xG-CM camera supports the dividing in three slopes.
To use this kind of HDR method the user has to define two pairs of parameters: (T1, SL1) and (T2, SL2).
•
T1 and T2 define portions of the total exposure time and the length of the three timing phases.
•
SL1 and SL2 define portions of the sensor saturation, so called kneepoint1 and kneepoint2.
