This function improves the contrast of images. This function can be set only when a color camera is connected
to the Controller.
Example:
Setting color filter processing
There are three ways of setting custom colors:
AUTO
The optimum filter is automatically selected from seven color
filters.
Select filter
This setting allows you to select from six color filters + gray filter to
match the color whose contrast is to be improved.
Custom filter
This setting allows you to set the color filter to any custom color.
You can select the desired color from the color palette.
For monochrome images, the color of the currently selected filter is displayed as white and complementary colors
are displayed as black. "Complementary colors" refers to colors that lie on opposite sides of the white point in a
chromaticity diagram.
Example: When the blue filter is selected, blue is displayed as white and yellow is displayed as black.
With regular monochrome image
conversion, the result is a low-
contrast image.
