ExposureMode [Enum] R/W

Control for exposure duration.

ExposureTimeAbs [Float] 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.

ExposureTimeAbs depends on ExposureMode as follows:

• ExposureMode = Timed: ExposureTimeAbs is sensor integration

time.

• ExposureMode = TriggerWidth: ExposureTimeAbs is ignored.

• ExposureMode = PieceWiseLinearHDR: ExposureTimeAbs

is the full sensor integration time. See ExposureTimePWL1 and

ExposureTimePWL2 for setting ThresholdPWL exposure dura-

tions.

ExposureTimeIncrement [Float] R/C

Increment/resolution of the exposure time in microseconds.

Timed [Default] Camera exposure time is set by Expo-

sureTimeAbs

TriggerWidth Camera exposure time is controlled by external

trigger pulse on Line1 or Line2. In order for

this feature to work, TriggerSelector =

FrameStart and TriggerSource must be

set to Line1 or Line2

PieceWiseLinearHDR Image dynamic range is increased in difficult

lighting situations by clamping down bright pix-

els with light levels beyond ThresholdPWL

limits. Overall camera exposure time is set by

ExposureTimeAbs. HDR sub-exposures are

set using ExposureTimePWL1 and Expo-

sureTimePWL2
