ExposureTimePWL1 [Float] R/W
Valid only when ExposureMode = PieceWiseLinearHDR. Exposure
time after ThresholdPWL1 is reached.
ExposureTimePWL2 [Float] R/W
Valid only when ExposureMode = PieceWiseLinearHDR. Exposure
time after ThresholdPWL2 is reached.
ThresholdPWL1 [Integer] R/W
Valid only when ExposureMode = PieceWiseLinearHDR. The first and
highest threshold level in PieceWiseLinearHDR. 0 = no light in pixel, 63
= full pixel light capacity.
Range: [Camera dependent] Unit: µs

Range: [Camera dependent] Unit: µs
Note

When ThresholdPWL2 is less than ThresholdPWL1 (i.e.
enabled), ExposureValuePWL2 must be greater than
ExposureValuePWL1.
Range: [0–63] Default: 63
Note

Leaving ThresholdPWL1 at 63 disables the first threshold
of PieceWiseLinearHDR mode, effectively disabling HDR
mode.
