Color Extraction; Color Filter - Sharp IV-C35M User Manual

1-2 Color extraction

The color extraction function extracts a color in a certain area from the original image, and registers it
as a reference color. The controller converts areas of color that are within the upper and lower limit
ranges of hue, saturation, and brightness of the reference color to binary images, as well as colors
outside of these ranges.
Then, the controller measures these binary images with conventional measurement procedures.
Effects of extracting color
Available measurement programs that can be used with the color extraction function are area
measurement by binary conversion, object counting by binary conversion, object identification by
binary conversion, color evaluation, color unevenness inspection, and color position measurement.

1-3 Color filter

Color filter is to filter red, green, blue, brightness, or optionally, the captured image, and display the
filtered color as bright gray.
Then, the controller measures these gray images with conventional measurement
