AVT GigE camera attributes

AVT GigE Camera and Driver Attributes V1.3.1

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

Offset

OffsetValue – Integer – R/W

Brightness (aka black level). Setting GainValue does not change the Offset-

Value.

SubstrateVoltage

VsubValue – Uint32 – R/C

Factory use only. CCD substrate voltage. Optimized at factory for each sensor.

Whitebalance

Unlike Hue or ColorTransformationControl, this is a pre-bayer interpolation

gain adjustment. Applies to all color PixelFormats.

Auto

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

following settings to the next image, i.e. the camera must be acquiring images

in order for the auto algorithm to update. Large changes in scene lighting may

require 2-3 frames for the algorithm to stabilize.

WhitebalAutoAdjustTol – Uint32 – R/W

A threshold. Sets a range of averaged scene color changes in which the auto-

matic white balance will not respond. Used to limit white balance setting

changes to only larger variations in average scene color.

WhitebalAutoRate – Uint32 – R/W

Determines how fast the auto white balance algorithm updates.

WhitebalMode – Enum – R/W

WhitebalValueRed – Uint32 – R/W

Gain applied to all red pixels on the CCD, pre-interpolation. 100% = no gain

applied. Each camera model calibrated with a different factory default.

Range: [0-255] Default: 0

Range: [Camera dependent] Units: mV

Range: [0 – 50] Default: 5 Units: percent

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

Manual [Default] Auto white balance is off. White balance can be

adjusted directly by changing the WhitebalValueRed and White-

balValueBlue parameters

Auto White balance will continuously adjust according to the current

scene. The Auto function operates according to the Auto and DSP

controls

AutoOnce The white balance will be set once according to the scene illumi-

nation and then remain at that setting even when the scene illu-

mination changes. The AutoOnce function operates according to

the Auto and DSP controls

Range: [Camera dependent] Units: percent
