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 Brightness Correction Mode is ON, the brightness will be consistent but the timing of image capture will
be delayed by 25 ms (when the shutter speed is 1/250 or faster, i.e., the exposure time is shorter).
When built-in lighting is OFF and the shutter speed is slower than 1/250, i.e., the exposure time is longer, the
image capture timing will be further delayed.
Make sure that appropriate images of the measured objects are captured when Brightness Correction Mode is
ON.
