Adjusting Image Brightness with External Lighting
You can adjust image brightness with external lighting or by setting the Sensor sensitivity.
Using a Strobe Trigger Signal to Control External Lighting
If a Data Unit is connected, you can change the output time of the strobe trigger signal (STGOUT) to adjust the
brightness.
Changing the Output Timing and Output Time of the STGOUT Signal: p. 270
Adjusting the Brightness
You can adjust the shutter speed/gain or the brightness to make images brighter. The setting method depends
on whether HDR Mode is ON or OFF. The setting methods are described below.
The exposure time will be longer for higher values of the shutter speed or brightness. This may cause the
image to blur if the object is moving fast. If the Sensor is used on a high-speed line, check that the images are
not blurred under actual operating conditions.
Brightness Correction Mode (FQ2-S1

/FQ2-S2

)
If the brightness changes inconsistently with each image, turn ON the Brightness Correction Mode.
When HDR is ON:
[Brightness]
−
−
[Brightness correction]
When HDR is OFF:
[Gain]
−
−
[Brightness correction]
When the Brightness Correction Mode is ON, the brightness will be consistent but the timing when images are
taken will be delayed by 25 ms. Make sure that appropriate images of the measured objects are taken when the
Brightness Correction Mode is ON.
Reference Timing Chart When the Brightness Correction Mode Is OFF: p. 236
If the gain is increased, the brightness will not be stable and measurement values may be inconsistent. We
recommend that you turn ON the Brightness Connection Mode.
