§ Run once
Select this check box to automatically disable the adjustment functionality as soon as the target
value is reached.
§ 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.
· Histogram area
With the histogram settings, you define the image area you want to use for determining the
average grayscale value. The following parameters are available:
§ Width
§ Height
§ Left
§ Top
By default the histogram area always equals the size of the current image. If you change the
size of the current image, the image area for determining the grayscale value is automatically
adapted to the new image size.
§ Show
Select this check box to display the defined histogram area as an overlay. The currently
calculated average grayscale value is also shown.
· Default
Click this button to reset all parameters to the model-specific defaults.
