ExposureValue – Uint32 – R/W
The sensor integration time. Values written to control are rounded to nearest
multiple of ExposureTimeIncrement. Reading this control returns the used,
rounded value.
ExposureValue depends on ExposureMode as follows:
• ExposureMode = Manual: ExposureValue is sensor integration time.
• ExposureMode = Auto/AutoOnce/External: ExposureValue is ignored.
• ExposureMode = PieceWiseLinearHDR: ExposureValue is the full sensor
integration time. See ExposureValuePWL1 and ExposureValuePWL2 for
setting ThresholdPWL exposure durations.
ExposureValuePWL1 – Float – R/W
Valid only when ExposureMode = PieceWiseLinearHDR. Exposure time after
ThresholdPWL1 is reached.
ExposureValuePWL2 – Float – R/W
Valid only when ExposureMode = PieceWiseLinearHDR. Exposure time after
ThresholdPWL2 is reached.

Note

When ThresholdPWL2 is less than ThresholdPWL1 (i.e.
enabled), ExposureValuePWL2 must be greater than Expo-
sureValuePWL1.
