GainControl/Gain

This feature controls the gain settings applied to the sensor.

Gain [Float] R/W

The gain setting applied to the sensor. For best image quality, the gain setting

should be set to zero. However, in low-light situations, it may be necessary to

increase the gain setting.

GainAuto [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 2–3 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 gain feature to respond only to a subregion within

the image scene. This subregion can be configured with the DSPSubregion

feature.

Note



The shutter feature is intended to control the exposure by

means of a mechanical shutter. It should not be confused

with any other exposure control feature.

The mechanical shutter is available ONLY on the Bigeye G-

629B Cool camera.

Range: [Camera dependent] Default: 0 Units: dB

Off [Default] The automatic mode is Off

Once Auto-gain occurs until target is achieved, then GainAuto

returns to Off

Continuous The gain will vary continuously according to the scene illu-

mination. The auto exposure function operates according

to the ExposureAutoControl and DSPSubregion

controls

Note



The camera must be acquiring images in order

for the auto algorithm to update.
