FH/FZ5 Processing Item Function Reference Manual
Specify a region on the image that includes the target color. The average color of the
specified region is registered.
Click the reference color on the color chart to specify it. The RGB values for the
specified color are displayed at the bottom.
The color to be detected is set with the RGB values.
This sets the allowable color difference for detecting the edge, using the specified color
as the reference. The larger the difference values, the larger the color range that is used
to detect the edge.
Color IN: The position where a color other than the specified color changes to the
specified color is detected as the edge.
Color OUT: The position where the specified color changes to a color other than the
specified color is detected as the edge.
