Acquisition parameters. The luminance of the acquired image can be controlled either explicitly through
exposure time and gain functions, or automatically through corresponding auto-functions.
Exposure time
The
Exposure Time
feature in
Acquisition Control
category configures the length of the exposure in
microseconds.
Analog gain
Analog gain to be applied on the sensor during acquired image digitization can be configured through
corresponding features in Analog Control category. Verify that the Gain Selector feature is set to Analog
(some cameras models support also digital gain). Now the Gain feature controls the desired analog gain
value in decibel.
Auto-functions
Selected camera models support automatic gain and/or automatic exposure functions, when the camera
keeps adjusting given parameter automatically, to maintain constant image luminance. The features will
be displayed in the feature tree only if the camera supports them. To switch the auto function on,
navigate to corresponding control feature, Automatic Exposure in Acquisition Control category or
Automatic Gain in Analog Control category and switch them from Off to Continuous.
Triggered acquisition. The camera starts by default in “free running” mode — acquiring continuous stream of
image frames. On the other hand in the triggered mode, the acquisition of individual frames can be explicitly
