By default (AUTO), a color filter that increases the contrast of “area of the largest color
group” and “area of the second largest color group” located inside the area will be
selected automatically.
If the contrast of the desired image is not increased with [AUTO], the filter color can be
changed to suit the image.

● Teaching Brightness
If this function is set to [ON] (default), even if the brightness changes due to fluctuation
of surround lighting, the sensor works well, thereby this function is useful to prevent
color pickup problems that may occur due to lighting fluctuation.
If this function is set to [OFF], workpieces whose brightness and vividness differ from
those of the workpiece that was “taught” first can be identified.
