Use the following settings to configure automatic brightness control:
Exposure (AES)
Select this check box to automatically adjust the image brightness based on the exposure shutter
setting.
Gain (AGC)
Select this check box to automatically adjust the image brightness based on the gain setting.
Framerate (AFR)
Select this check box to adjust the frame rate in such a way that the exposure shutter is
optimized. This option is only available when AES is active.
Run once
Select this check box to automatically disable the adjustment functionality as soon as the target
value is reached.
Use sensor auto features
If your sensor offers automatic image brightness adjustment, you can select this check box to
enable the feature. Thorlabs DCx cameras do not support this feature.
Brightness reference
Default average grayscale value (brightness) of the image.
Exposure limit
Sets the upper limit for the exposure time. Gain control is activated as soon as the upper limit of
the exposure time is reached.
The maximum value for automatic exposure time control is linked to the camera settings. If the
maximum possible exposure time value has changed, e.g. through changes in the timing
parameters, then this value is applied as the maximum Auto Exposure value. Set values that are
less than the maximum value are not affected.
Gain limit
Sets the maximum gain limit. On reaching the lower limit (gain = 0), the exposure time adjustment
range is activated.
Speed
Sets the adjustment speed. The higher the speed control is set, the faster the adjustment. Setting
the speed control to 0 disables the adjustment functionality. See also Speed in Automatic
Image Control
Hysteresis
Sets the hysteresis range for control stabilization. See also Hysteresis in Automatic Image
Control
Skip frames
Sets the number of frames that will be skipped during automatic image control when in freerun
mode is active. See also Skip Frames in Automatic Image Control
Histogram area
The histogram area specifies which area of the image will be used for calculating the average
grayscale value of the image.
You can set the size of the histogram area by using the tools on the toolbar.
Default
Click this button to reset all parameters to the model-specific defaults.
