About this Manual:
This manual describes the measurement conditions, settings, and external device communications methods for the F400 Color Vision Sensor. The F400 can take measurements using color information.
The F400 supports two scene modes that can be used for measurement: Color Pickup Mode and Color
Filter Mode. The features of these two scene modes are as follows:
Color Pickup Mode: Only the specified color is extracted and measured.
Color Filter Mode: A color filter is applied to create an easily measurable image. Color combinations
that are hard to distinguish in gray images because of low contrast in brightness,
such as green and yellow, can be recognized and measured.
Please read this manual and other related manuals carefully and be sure to understand the information
provided before attempting to install or operate the F400. The manuals for the F400 are outlined in the following table.

1 Safety Precautions
WARNING Cover the terminal blocks with the Terminal Block Protection Covers.
Uncovered terminal blocks can result in electric shock.
WARNING Use DC power supplies with safe extra low-voltage circuits on the
secondary side for the main F400 power supply and power supplies for
the terminal blocks. Excessively high voltages can result in electric
shock.
Caution Do not touch fluorescent or halogen lights while the power is ON or
immediately after the power is turned OFF. These lights generate heat
and can cause burns.
Caution Do not use the F400 in environments with flammable or explosive gases.
Caution Install the F400 away from high-voltage equipment or motors to ensure safety during
operation and maintenance.
Caution Use the power supply cables and crimp terminals of specified sizes.
Caution Use at the power supply voltages specified in this manual.
Caution Be sure to securely tighten the screws when mounting F400 components.
Caution Do not dismantle, repair or modify any F400 components.
Caution Dispose of F400 components as industrial waste.
Caution To prevent damage from static electricity, use a wrist strap or another device for pre-
venting electrostatic charges when touching terminals or connector signal lines.
Caution Do not turn OFF the power while a message is being displayed indicating that proces-
sing is being performed. Data in memory will be destroyed, and the F400 may not
operate correctly the next time it is started.
2 General Precautions
The user must operate the product according to the performance specifications
described in the operation manuals.
Before using the product under conditions which are not described in the manual or
applying the product to nuclear control systems, railroad systems, aviation systems,
vehicles, combustion systems, medical equipment, amusement machines, safety
equipment, and other systems, machines, and equipment that may have a serious
influence on lives and property if used improperly, consult your OMRON representative.
Make sure that the ratings and performance characteristics of the product are sufficient for the systems, machines, and equipment, and be sure to provide the systems,
machines, and equipment with double safety mechanisms.

1-1 Features
Color Images
Color information from a color image can be used when performing measurements.
Select one of the two F400 measurement modes, called scene modes, depending on
the application. The two modes are Color Pickup Mode and Color Filter Mode.
Refer to t h e
Introduction Manual (Z131)
for information on color (hues and saturation)
and applications.
Color Pickup Mode
The Color Pickup mode is used to extract only specified colors. Simply click the color
to be displayed on the screen to register it as a pickup color. Up to 8 colors can be
registered per scene.
Applications include separation by color, such as for ice cream separation or for wiring checks.
Color Filter Mode
A color filter can be applied to create an easily measurable image. There are five color
filters: Red, green, blue, colorgray, and gray. The colorgray filter is used to convert a
color image to a grayscale image with 256 gradations by using hue and saturation
settings. The colorgray filter enables measurement of color combinations, such as
green and yellow, with low contrast in brightness making them hard to distinguish in
gray images.
Applications include detection of small defects, such as surface defects on bottle
caps, and inspection free from background distortion, such as inspecting the amount
of adhesive that has been coated on a surface.

• Position and orientation of object can be compensated before measurement. → p. 37
There are four methods: Using search, edge, area and center of gravity, or center of gravity
and axis angle.
• Color of object and color read by camera can be adjusted automatically using white balance.
→ p. 96 Adjust white balance each
time lighting is changed.
• Camera image can be adjusted to facilitate measurement.
Filtering: Edges of object are enhanced and noise reduced.
→ p.
33
Background suppression: Background of object, such as pat-
terns, is excluded from measurement.
→ p. 34
Color filter: Contrast of measurement area is increased
→ p.24
• Up to 8 specified colors can be picked up.
→ p. 28
• Images can be checked on screen. Up to 16 images can be stored
in memory to confirm past images to see what problems have
occurred. Images can be backed up on a computer.
→ p. 100
• Setup can be changed smoothly.
→ p. 16 Each of 16 scenes can be
set up for different inspection
conditions. Change scenes to
setup a different measurement
object.

• Communications with external devices is possible through a
terminal block or RS-232C port. Refer to the table on the next
page.
•The distance between two regions or the maximum value
can be obtained by calculating measured values or by
using functions.

1-2 Measurement Modes
There are five measurement modes. Different modes are available depending on the
scene mode.
1-2-1 Color Pickup and Color Filter Modes
Search → p. 55, 144
Density searches are used when inspecting the shape of specific objects. The object
is measured using a registered measurement pattern called a model. The position of
the object and the degree of conformity, called the correlation, with the model are calculated.
Edge
→ p. 63, 140
The edge measurements are used to find the coordinates of edges of the measurement object. The width of an object can be calculated by using an equation to subtract
edge coordinates.
Area and Center of Gravity
→ p. 67, 147
The binary center of gravity and area can be used to calculate the size (i.e., the area)
and the position (i.e., the center of gravity) of the measurement object.
Center of Gravity and Axis Angle
→ p. 67, 147
The binary axis angle can be used to calculate the orientation (i.e., the binary axis) of
the measurement object, in addition to the center of gravity and area. Binary axis
searches increase processing time, so binary center of gravity and area searches
should be used when only the center of gravity and area are required.
1-2-2 Additional Color Filter Mode
Surface Defects → p. 52, 142
The measurement object can be inspected for surface defects. Areas that are largely
different in densities are detected as defects.
