GigE Camera and Drivers Features V3.0.0

This document is a master document for all Allied Vision GigE camera models and is NOT camera specific

DefectMask

Some larger format sensors may contain defective columns. Class 1 and Class 0

sensors are available with no defective columns.

DefectMaskColumnEnable [Enum] R/W

Defect masking replaces defective columns with interpolated values based on

neighboring columns. Defective columns are detected and recorded at the fac-

tory.

DefectMaskPixelEnable [Enum] R/W

Currently NOT implemented.

Exposure

ExposureAuto [Enum] R/W

Auto algorithms use information from the camera’s current image and apply the

following settings to the next image. Large changes in scene lighting may

require several frames for the algorithm to stabilize.

If using ExposureAuto = Continuous, and GainAuto = Continuous

simultaneously, priority is given to changes in exposure until ExposureAu-

toMax is reached, at which point priority is given to changes in gain. Adding

simultaneous IrisMode = Video/DCIris/PIrisAuto results in unde-

fined, “race to target” behavior.

You can configure the auto exposure feature to respond only to a subregion

within the image scene. This subregion can be configured with the DSPSub-

region feature.

Enabled [Default] Enables masking of defective columns

Disabled Disables masking of defective columns

Off [Default] The automatic mode is Off

Once Valid when ExposureMode = Timed or PieceWise-

LinearHDR. Auto-exposure occurs until target is

achieved, then ExposureAuto returns to Off

Continuous Valid when ExposureMode = Timed or PieceWise-

LinearHDR. The exposure time will vary continuously

according to the scene illumination. The auto exposure

function operates according to the ExposureAuto and

DSPSubregion controls

Note



The camera must be acquiring images in order

for the auto algorithm to update.
