Introduction

1-1 FQ-series Vision Sensors

FQ-series Vision Sensors are real-color Vision Sensors with integrated processing. Once configured, they are
used stand-alone for quality inspection of presence, position, and other product characteristics. To set up or
monitor the sensors, either the touch screen based console 'Touch Finder' or a 'PC Tool' can be used.

Setup, Image Confirmation, and Logging Tools

Touch Finder

FQ Vision Sensor

Used to check images and set the judgement
parameters. It can also be used to save
measurement results and check status during
operation.

PC Tool

Includes the camera, lighting, measurement
processor, and I/O functions.
After the Sensor has been set up, it can be
operated alone to perform measurements
without the Touch Finder or PC Tool.

The same functions as those that are provided
by the Touch Finder can be performed from a
computer. The PC Tool is available free of
charge.

FQ-series Vision Sensors are available in two different models. The differences are given in the following table.

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.

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

improve the quality of the images.

Polarizing filter Specular reflections can be eliminated from an image by attaching a polarizing filter to the

Sensor.

• Selection Tips

• When the measurement object is not moving → Use the HDR function.

• When the measurement object is moving → Use a polarizing filter.

3

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 (exposure times) so that the resulting image has a lower degree of
contrast and can be measured stably for the desired characteristic.

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.

[Image] − [Camera setup]

1 Press [ ] − [Brightness] on the right side of the display.

3 Press the [OK] Button.

Note

• If the measurement object is changed after setting the HDR function, press
the [AUTO] Button to automatically set the HDR mode again.

• If the automatic selection does not achieve the desired results, press the
[HDR] Button and manually set the best HDR mode. As shown below, the
higher the level, the wider the combined dynamic range will be.

• If the reflections cannot be sufficiently removed using the HDR function,
use a polarizing filter as well.

Using a Polarizing Filter

Specular reflections can be eliminated from an image by attaching a FQ-XF1 Polarizing Filter to the Sensor.

Observe the following precautions.

• The image will be darker compared to when no filter is used.

• If the image becomes too dark, adjust the brightness.

Adjusting the Colors of the Image (White Balance)

If external lighting is used, the image may appear as having different colors than the actual object. If this is the
case, adjust the white balance.
If the lighting built in to the Sensor is used, the white balance is already adjusted. No setting is required in this
case.

3-3 Adjusting the Object Position

If objects are moving, the position in the image of the characteristic that is to be measured will vary according
to the timing of the trigger signal. The FQ Vision Sensor offers two different ways to adjust this position
variation.

Function Description Reference

Position compensation If the timing of the trigger is accurate, the FQ Vision Sensor can correct variations in the

position of the object for each measurement with the Position Compensation function.

Trigger delay A delay can be applied from when the trigger (the TRIG signal) is input until when the

image is input, to synchronize the timing of image input with the speed of the moving
objects.

Position Compensation

The FQ Vision Sensor performs measurements in measurement regions that are set to a fixed shape and
position by the operator. A measurement is not performed properly if the object is not positioned inside this
measurement region (e.g., the result will be NG even if the object is OK). In machines in which the position of
the object varies for each image, stable measurements would be impossible. To cope this problem, the Position
Compensation function aligns the whole image so that the object to be measured is moved exactly to the
measurement region.

Reference position (as set by the operator)

The measurement object is properly within the measurement region.

Adjusting the Image Timing

The internal timing for taking an image can be set to be delayed in relation to the external trigger signal. This
can be used to adjust the object position in the image, e.g., if an external trigger sensor is used. If the object
position still varies in the image the Position Compensation function must also be used.

Delay from when the trigger is input until
when Sensor input is started.
