Overview of FQ2-S/CH Series

The FQ2-S/CH Series features Vision Sensors with integrated cameras and controllers. They can be used to
easily achieve simple inspections
You can use parallel controls, no-protocol communications on Ethernet, PLC Link communications on Ethernet,
and EtherNet/IP communications on Ethernet as standard features. You can also use a Data Unit to enable
control with full-scale parallel communications or RS-232C communications.
To set up and monitor the Vision Sensor, you can use either the Touch Finder or the PC Tool running on a
computer. For actual operation, you can use the Vision Sensor on a stand-alone basis.

Preventing Chattering

• The Sensor is equipped with an anti-chattering function, but if the chattering is 100 μs or longer, a faulty input may
occur. (Input signals of 99 μs or shorter are ignored. Signals of 100 μs or longer are treated as input signals.)

• Use no-contact output devices (e.g., SSR or PLC transistor output) for the input signals. If contacts (e.g., relay) are
used, chattering may cause the trigger to be input again during execution of a measurement.

Adjusting the Brightness

You can adjust the shutter speed/gain or the brightness to make images brighter. The setting method depends
on whether HDR Mode is ON or OFF. The setting methods are described below.

HDR Function: p. 70

The exposure time will be longer for higher values of the shutter speed or brightness. This may cause the image to
blur if the object is moving fast. If the Sensor is used on a high-speed line, check that the images are not blurred under
actual operating conditions.

Brightness Correction Mode (FQ2-S1

If the brightness changes inconsistently with each image, turn ON the Brightness Correction Mode.
When HDR is ON: [Brightness] − − [Brightness correction]
When HDR is OFF: [Gain] − − [Brightness correction]
When Brightness Correction Mode is ON, the brightness will be consistent but the timing of image capture will
be delayed by 25 ms (when the shutter speed is 1/250 or higher).
When built-in lighting is OFF and the shutter speed is less than 1/250, the image capture timing will be further
delayed.
Make sure that appropriate images of the measured objects are captured when Brightness Correction Mode is
ON.

Improving the Image Quality of Metallic and other Shiny Surfaces

When objects with shiny surfaces are being measured, the lighting may be reflected off the surface and affect
the image.
To remove reflections, one of the following two functions can be used.

Function Description

HDR (High Dynamic Range) If objects have contrasting light and dark areas, the dynamic range can be made wider to

Polarizing filter (for Sensors
with Built-in Lighting)

improve the quality of the images.

Specular reflections can be eliminated from an image by attaching a polarizing filter to the
Sensor.
If the measurement object must be moving, use a polarizing filter. Also, if reflections can­not be sufficiently removed by using the HDR function, use a polarizing filter as well.

HDR Function

The HDR function is used for objects that have a large difference between light and dark areas. For this kind of
object, clear images cannot be achieved with the standard brightness setting. The HDR function combines
several images of different brightnesses (shutter speed) so that the resulting image has a lower degree of
contrast and can be measured stably for the desired characteristic.

70

Adjusting Image Quality

FQ2-S/CH User’s Manual

Observe the following precautions.

• Use the HDR function only for objects that are not moving to avoid image blurring.
Several images are taken with different shutter speeds and combined. If the object moves while the image
is being taken, the image will become blurred.

• Images with different brightnesses are combined, so the resulting image will have a lower degree of con­trast.

Delaying the Image Capture Timing from the Trigger Input

If the measurement object is moving, the position in the image of the feature that is to be measured will depend
on the timing of the trigger signal. A delay can be applied from when the trigger (i.e., the TRIG signal) is input
until when the image is taken to synchronize the timing of image capture with the speed of moving objects. If
the object position varies in the image, this delay cannot be used to make the object position more stable.
When you use a trigger delay with external lighting, you will also need to adjust the timing to turn ON external
lighting.

Preventing Mutual Interference of Multiple Sensors

When the same trigger signal is input to multiple Sensors, the lighting from one Sensor may affect the
measurements of the other Sensors. This is called mutual interference. This kind of interference can be
prevented offsetting the image input timing of each Sensor from when the trigger signal is received.
Example:
A trigger (i.e., the TRIG signal) is input to Sensor 0 and Sensor 1 at the same time.

Image Adjustment

You can adjust the image that is taken by the Sensor to make it easy to measure.
There are mainly the following two types of items that you can use to adjust the image.

• Filtering the Images (Filter Items)
These items filter the image by eliminating image noise with filters to make them suitable for measurement.

• Compensating for Position Offset (Position Compensation Items)
These items compensate for offset in the position or orientation of the image.

You can combine several filter items and position compensation items to adjust the image that was taken. (You
can use a total of up to eight filter and position compensation items combined.)

Flow of Image Adjustment

The image that is taken by the Camera (called the Camera image) is adjusted in the order that the filter and
position compensation items are registered.

You can specify the order of image adjustment by registering the items in the desired order, but you cannot change
the order of the items after you register them.

Applying the Results of Position Compensation

You can apply the results of position compensation either to the Camera image or to the previous image from
before position compensation was applied.
If you apply the results of position compensation to the Camera image, only the position information from
position compensation is applied to the image to be measured.

• Using Filter Items for Processing with Position Compensation Items

To more effectively perform position compensation, filter items can be used to create an image specifically for
position compensation and then apply only the results of processing the position compensation to the image
that will be measured. The processing order of filter and position compensation items and the settings of the
source images are set up as shown below.

Edge Rotation Position Compensation

This position compensation item detects an edge in two directions.
If the specified color is detected (or the specified density is detected for a Sensor with a Monochrome Camera),
it is recognized as an edge. Two edge positions are detected.
The image is adjusted so that the two edge positions match the positions when the edge positions were
registered.
