autogain
“autogain” gchararray
(off, once, continuous) Controls whether the camera will try to adjust the gain settings. Setting this parameter to
anything but "off" will override the exposure parameter. Running the plugin without specifying this parameter will
reset the value stored on the camera to "off".
Flags: Read, Write
Default value: "off"
gain
“gain” gdouble
(dB) Sets the gain added on the camera before sending the frame to the computer. The value of this parameter
will be saved to the camera, but it will be set to 0 every time this plugin is launched without specifying gain, or it
will be overridden if the autogain parameter is set to anything that is not "off". Reconnect the camera or use the
reset parameter to reset the stored value. Range: 0.0 to 12.0
Flags: Read, Write
Default value: 0.0
blacklevel
“blacklevel” gdouble
(DN) Sets the stream's black level. This parameter is processed on the camera before the picture is sent to the
computer. The value of this parameter will be saved to the camera, but it will be set to 0 every time this plugin is
launched without specifying this parameter. Reconnect the camera or use the reset parameter to reset the
stored value. Range: 0.0 to 63.75
Flags: Read, Write
Default value: 0.0
gamma
“gamma” gdouble
Sets the gamma correction value. This parameter is processed on the camera before the picture is sent to the
computer. The value of this parameter will be saved to the camera, but it will be set to 1.0 every time this plugin
is launched without specifying this parameter. Reconnect the camera or use the reset parameter to reset the
stored value. Range: 0.0 to 3.9
Flags: Read, Write
Default value: 1.0
reset
“reset” gchararray
(off, before, after). Controls whether or when the camera's settings will be reset. Setting this to "before" will wipe
the settings before the camera initialization begins. Setting this to "after" will reset the device once the pipeline
closes. This can be useful for debugging or when using the camera with other software that does not reset the
camera settings before use (such as PylonViewerApp).
Flags: Read, Write
Default value: "off"
