Special Features
Implements the highest detection power possible with the KEYENCE
pioneered “Color gradation processing” (Patent pending).
• Reliably detects only the designated colors.
Enables the reliable extraction of targets that are hard to differentiate with
conventional monochromatic processing. (e.g. differentiation of yellow on white,
dark blue from black, and gold plate from silver plate, etc.)
A change of background colors does not require a change of settings, because the
CV-701(P)/751(P) detects the registered colors exclusively.
• Shadows on the target surface do not cause malfunctions.
Detection is unstable with conventional monochromatic processing, which detects
the brightness of the target, because it is affected by shadows given by the shape
of the targets and by the varied illumination distributions. Color concentration
processing enhances stability dramatically because detection is based on the color
differences.
■ Operating principals
The CV-701(P)/751(P) converts the color signal of the image captured by the
camera into R/G/B/ digital data using an A/D converting circuit.
It obtains the data of R-G, G-B, R-B based on the
converted digital data. The measurement area for
the color extraction is set based on six parameters.
The [AREA] mode (color binary conversion processing) operates detection by judging whether the
measured values are within or outside the color
extraction area. The colors within the color extraction area are of the maximum gradation level (255
levels of gray) with color concentration processing. The CV-701(P)/751(P) operates gray processing by converting the color data into a monochromatic image so
that the level is reduced as the color falls outside the area.
This processing method realizes stable detection for colors with different values
but with the same hue, and for colors without a hue such as white, black, and
gray.
Simple operation for highly sophisticated image processing functions.
Saves boot-up time dramatically.
• Simple “click extraction”: Simply place and click the cursor on the color
area to be detected to set the colors for extraction. No complicated
parameter settings are necessary.
Setting is simple enough for first-time use for sophisticated image processing.
Loaded with special features
• The screen-saving function allows you to go back and check a former
detection screen.
• The CompactFlash memory comes standard with the CV-701(P)/751(P).
Back up of the detection hysteresis and multiple programs, and copying
between controllers can be operated easily without using a personal
computer.
• The measurement result can be output in analog voltage (0 to 4 V).

4. Adjust the monitor. (with the CV-751(P) only)
The monitor for the CV-751(P) is factory-adjusted so that adjustment is unnecessary under normal conditions. If you need to make adjustments due to ambient light or the viewing angle, follow the procedure below.
* The initial setting is for setting all trimmers to the middle position.
1) Adjust the color depth using the COLOR adjustment trimmer.
2) Adjust the hue using the HUE adjustment trimmer.
3) Adjust the brightness using the BRIGHT adjustment trimmer.
5. Adjust the time and date.
The CV-701(P)/751(P) comes standard with a built-in clock function.
The time and date on the clock are used when writing the data on the
CompactFlash memory, etc.
Adjust the time and date using the [CLOCK] on the configuration menu.
➮
See page 149.
Note 1: The secondary battery for backing up the clock function is not factorycharged.
The battery can be fully charged by applying power to the controller for 24 hours.
Note 2: With the power off, the time between battery recharges is approximately
two months (at a temperature of 25 °C (77°F)). When it becomes low in capacity,
the date and time are reset to the initial setting. (00 YEAR 01 MON 01 DAY 00 MIN

2.2 Illumination
Use illumination for more stable detection.
If you install the CV-701(P)/751(P) in a location with the following conditions,
detection may not be accurate. Change the location or use the specially designed
illuminator.
• Locations directly exposed to sunlight
• Locations in which the ambient light varies greatly depending on the time of day
• Locations in which the illumination level changes according to the movement of
a machine or people
Illuminator
■ Ring lamp
Mount the ring lamp around the lens to illuminate the target evenly. The ring lamp
is available as an option. (CV-R11)
Note: The illumination lamp has a recommended service life. When the light
intensity changes, detection errors may result. Replace the lamp before this
problem occurs.
White balance
Adjust the white balance when discoloration occurs in the target image after the
lens and illumination are adjusted.

3.1 Measurement Modes and Typical Applications
The CV-701(P)/751(P) features five measurement modes: “ARE/CON” (Area
continuous), “INS/TRG” (Inspection trigger), “INS+POS” (Inspection + position),
“ABS.POS” (Absolute position), and “REL.POS” (Relative position). This section
gives an overview and describes the typical application of each mode.
3.1.1 “ARE/CON” (Area continuous)
Use “ARE/CON” mode to continuously measure the area in the window for selected color data.
➮
See“4.4 “AREA” Mode Basic Settings” on page 57 for the setting procedure.
Functions
• Extracts the selected color data of the window.
• Sets a window and measures the area of the selected color data and the
background color of the window.
• Up to eight windows can be drawn for a single program. The measured data
and detection result for each window are output sequentially.
Sample: Detection for the number of pixels
T ypical applications
Use the “AREA” mode for detection of the presence or absence of a target, a
missing target, and for the shape or area of a target.

Basic Unit of Area: “Pixel”
The sensing element CCD of the camera forms a
square grid pattern, and each minute area corresponds
with a pixel. Each pixel recognizes R, G, and B as a 256level brightness signal.
“AREA” mode allows you to set a window on a desired
part of an image on the monitor screen and count the
number of pixels matching the selected color data.
You can detect the area of a target, whether it is small
or large, and the presence or absence of a target.
3.1.2 “INS/TRG” (Inspection trigger)
Use “INS/TRG” mode to measure the selected color data in the window at every
trigger input.
➮
See “4.6 “INS” Mode Basic Settings” on page 70 for setting procedure.
Functions
• Selects the measurement parameter by the inspection mode.
• The following ten inspection mode types can be selected from the inspection
mode.
• Setting an inspection mode for each window allows for multiple detections with
one target.
AREA
Detects the presence or absence of a target, whether it is small or large, a missing
target, and the area of a target as with “ARE/CON” mode.
OUTER (Outer edge)
Measures the distance between the outermost edges in the window.
INNER (Inner edge)
Measures the distance between the innermost edges in the window.
GAP
Measures the distance between the odd-numbered edges and the even-numbered
edges counted from the left (in horizontal scanning) or top (in vertical scanning) of
the window. The maximum, minimum, and average values can be obtained.
