xiQ - Technical Manual Version 1.0
67
The dynamic range can be increased by dividing the integration (exposure time) in two or three phases (slopes), with different
maximum saturation levels. The xiQ cameras support 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.
