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.
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
Filter types
R (red) filter
G (green) filter
B (blue) filter
Brightness filter
Custom filter
The color filter function can be used with positional deviation measurement, degree of match inspec-
tion, lead inspection, BGA/CSP inspection, area measurement by binary conversion, object counting
by binary conversion, object identification by binary conversion, point measurement, multiple posi-
tion measurement, multiple degree of match inspection, and fault inspection.
Computer link
Programmable controllers (PC) are equipped with communication protocols. The "computer link" is
used to transfer data between the PC and an external computer, or the like, using this communica-
tion protocol. The IV-C35M supports the computer link protocols used by Sharp, Omron, Mitsubishi,
and Yokogawa PCs. Therefore, the PC does not need a custom communication program in order to
create a computer link with the IV-C35M.
Contraction
See "Expansion and contraction to eliminate binary noise in the image."

Edge detection
The "edge" refers to the boundaries between the brighter (white) and darker (black) parts in an
image. The "edge detection" function is used to detect this boundary by processing the image.
