When the “Auto” checkbox is activated for cameras that provide for the
AutoGain/AutoExposure feature, the “Luminance” panel changes to show the
settings that apply to this mode of operation. The manual settings for gain and
offset will disappear since the luminance will be controlled automatically.
The automated luminance control algorithm takes advantage of both, exposure
and gain settings. First the exposure will be tried to adjust it such that a set
brightness value will be met. Once the highest exposure value has been
reached the algorithm will further increase luminance by increasing camera’s
gain. The upper and lower limits for both controls are available in the
“Luminance” panel once the “Auto” checkbox is checked.
The actual exposure is shown on the “Acquisition” panel and the actual gain is
displayed in the “Luminance” panel on the left to the “min” and “max” gain
settings.
In “Manual” mode the sliders can be used to increase the gain factor related to
the tap. So differences in brightness can be eliminated.
Factory balance will be displayed as 0 db. The slider can also be used for
manually adjusting gain from 0 to 6.0 db for each tap.
When switched to “Auto / Once”, captured images will be checked for tap
balance and in case of a deviation, new left/right gain factors will be
determined and be sent to the camera. As soon as a balance is achieved
between left and right channel, the mode returns to “Off” automatically.
