ExposureAutoOutliers – Uint32 – R/W

With ExposureAutoTarget as the mean target brightness, ExposureAutoOutli-

ers is the percentage of pixels on the upper bound of the image brightness dis-

tribution graph that are ignored by the ExposureAuto algorithm. This can be

used limit the effect of small specular bright spots on the overall image bright-

ness calculation.

ExposureAutoRate – Uint32 – R/W

The rate at which the auto exposure function changes the exposure setting.

ExposureAutoTarget – Uint32 – R/W

The general lightness or darkness of the auto exposure feature; specifically, the

target mean histogram level of the image—0 being black, 100 being white.

ExposureMode – Enum – R/W

ExposureTimeIncrement – Float32 – R/C

Increment/resolution of the exposure time in microseconds.

Range: [0 – 1000] Default: 0 Units: 0.01% i.e. 1000 = 10%

Range: [1 – 100] Default: 100 Units: percent

Range: [0 – 100] Default: 50 Units: percent

Manual [Default] The camera exposure time is fixed by Expo-

sureValue parameter

Auto The exposure time will vary continuously according to

the scene illumination. The Auto exposure function

operates according to the Auto and DSP controls

AutoOnce A command. The exposure will be set once according to

the scene illumination and then remain at that setting

even when the scene illumination changes. The

AutoOnce function operates according to the Auto and

DSP controls

External When ExposureMode is set to External the exposure time

will be controlled by an external signal appearing on

SyncIn1 or SyncIn2. In order for this feature to work, the

parameter FrameStartTriggerMode must be set to

SyncIn1 or SyncIn2

PieceWiseLinearHDR Image dynamic range is increased in difficult lighting sit-

uations by clamping down bright pixels with light levels

beyond ThresholdPWL limits. Overall, camera exposure

time is set by ExposureValue. HDR sub-exposures are set

using ExposureValuePWL1 and ExposureValuePWL2

Range: [Camera dependent] Units: μs
