Overview

Chapter 1: Overview

The IV-S20 compact image sensor camera is equiped with a CCD image sensor, which captures square
pixels in full range. Employing this state-of-art device, it can be used to pick up high contrast images at high
speed.
It is also easy to interface to a personal computer and a programmable controller, and it can be used in a
variety of production lines such as those for electrical, electronic, semi-conductor or liquid crystal parts as
well as for food, chemical, cosmetics, and other production lines.

1-1 Features

[1] Features of the CCD camera

(1) Arrangement of the square pixels

The vertical and horizontal pixel aspect ratio is 1:1, so there is no need for image correction. This
allows maximum precision and processing speed.

(2) Full pixel reading (progressive scan)

The IV-S20 employs a full pixel reading system which scans every horizontal lines on the CCD in
order. This system does not suffer from reduced image resolution which is caused by the
conventional NTSC interlaced system which only reads half the lines in each frame.

- Comparison of capturing moving objects image

(3) Random shutter

The IV-S20 shutter operation can be triggered by an external signal or by the CCD. It can be used
to mesure moving object.

(4) Reading full and partial images

Since the IV-S20 can be used to capture just the part of the image needed for image processing, it
can read images at very high speeds.

(5) CCD trigger

The IV-S20 samples a part of the CCD (which can be set to any position with according to item ),
and it will starts shutter operation when value of the area being monitored exceeds 50%. With this
function, there is no need for an additional photo sensor or proximaty sensor. Since the IV-S20 can
set the CCD triggering position for each item being processed, it can shorten the time needed to
change the items being processed on a production line.

(6) The C mount module and back plane focus can be adjusted

Since the IV-S20 uses a standerd C mount module for installing the lens, it can be used to adjust the
back plane focus and is convenient for use with a fixed focus lens or for proximaty shots.

Overview

[2] IV-S20 features

(1) Gray scale search using normalization correlation

The IV-S20 processes 256 gray level images using template matching
with normalization correlation. This improves inspection and measure­ment precision without being affected by variations in lighting.

(2) Sub-pixel level precision

When the IV-S20 looks for the position of an object using gray scale
search function, it can calculate a finer position than the actual CCD
pixel size by interpolation to achieve sub-pixel scale precision.

(3) Simultaneous shutter triggering of two cameras

When a trigger signal is input, two cameras will start
their shutter operation at the same time, and transfer
the captured image signals at the same time. This can
reduce the total processing time for taking simulta­neous pictures of moving objects.

(4) 8 kinds of integrated measuring programs, including measurement and inspection functions

The IV-S20 integrates the following measurement programs: Positional deviation, absolute position
measurement, matching level inspection, distance and angle measurement, lead inspection, area
measurement by binarization, counting by binarization, labeling measurements by binarization, and
point measurements. The IV-S20 can process any three measurements from 7 programs, plus po­sitional deviation and absolute position measurements, with one scanned image.

(5) Binarization processing is effective in controlling variations in brightness

Since the binarization process employs a brightness level monitoring function, the threshold value
will follow variations in brightness.

(6) Image pre-processing and binary noise elimination function

In order to process images precisely and reliably, the binarization process uses edge emphasis,
edge extraction, and leveling operations. To eliminate noise, "binary increase _ decrease," "de­crease _ increase," and "area filters" are available.

(7) Rotation correction

Rotation correction determines the angle for correction by locating two points with a gray scale
search and edge detection.

(8) Calculation between images

Calculation of difference between images captured by camera 1 and camera 2, and calculation of
differences between a stored standard image and captured images are both possible. Subtraction
and absolute difference in value can be used for calculation.

(9) Integrated PC function

The integrated calculation functions of a programmable controller are included so that the IV-S20
can directly output detection and measurement results after calculation external equipment. This
can greatly reduce the total processing time and produce cost savings when setting up a system.

(10) High speed programless communication

The IV-S20 has a computer link function and general-purpose serial communication function for
communication with external devices. It can have a user settable communication speed up to 115.2
kbps, which contributes to increased processing speed for the whole system.
The computer link function can write the measurement results to an external programmable control­ler register without any programing.
Using the general-purpose serial communication function, the IV-S20 can execute commands from
a host computer, and return the result to the host computer.

(11) Compact

The IV-S20 can be connected to a maximum of two cameras. It is the smallest image processing
system in the industry with the dark and light processing capabilities (as of August 1998).

(12) Simultaneous display of two screens

The screen can display two images from two cameras alternately, or simultaneously by dividing the
screen into two horizontally. When displaying multiple images, each camera image can be posi­tioned in the upper, middle, or lower views.

(13) Crosshair cursor display

A crosshair cursor is displayed. This cursor is convenient for manual positioning.

(14) Display language changeable between Japanese and English

Menus and other messages displayed on the screen can be switched between Japanese and En­glish.

Overview

1-2 Measurement program

The IV-S20 integrates the following eight measurement programs: Positional deviation, absolute position
measurement, matching inspection, distance and angle measurement, lead inspection, area
measurement by binary conversion, object counting by binary conversion, labeling measurements by
binary conversion, and point measurements.
You can select operating condition parameters to suit your application of the IV-S20.

- The specified pixel area is converted to a binary image. The number of objects, total
size of the white area (the objects) and the area, center of gravity, main axis angle, fillet
diameter, and circumference of each white area can be measured.

DATA SAVE? (YES=[SET]/NO=[ESC])

Chapter 2: Precautions for use

Pay attention to the points below when handling the IV-S20.

(1) Installation

- Each device in the IV-S20 system must be installed in an environment as specified in this manual.
(Operating ambient temperature: 0 to 45˚C, operating ambient humidity: 35 to 85%RH (non­condensing.))

- Do not install the devices in the following locations. Installation in any of these locations may cause
electrical shock, fire, or malfunction of the devices.

1. Places exposed to direct sunlight

2. Places with exposed to corrosive gases

3. Places with excessive amounts of dust, salt, or metal powder in the air.

4. Places exposed to water

(2) Installation

- Make sure to tighten the mounting and terminal screws securely and check everything before
supplying power. A loose screw may cause faulty operation.

(3) Power source

- Do not use the IV-S20 (power supply for the IV-S20 main housing) power supply with any other
equipment.

- Do not turn OFF the power while the menu is displayed or while communicating with external
equipment. Turning OFF the power may erase the data settings.

(4) Data saving

- The data set by using the remote setting key is temporarily stored in the memory (RAM) of the IV­S20. However, it is not stored in the flash memory yet. Therefore, make sure to save the data
settings before returning to the operation screen from the [SYSTEM SETUP] menu by pressing the
SET key. If you do not save the data, the data will disappear if you turn OFF the power to the IV-S20
main unit or if you change the item numbers to be processed.

- We recommend that you save the data settings and reference images on a floppy diskette using the
data backup tool.

(5) Storing the devices

- Do not put any object on top of any of the devices, or the device may malfunction.

(6) Maintenance

- Be careful not to get any dirt or stains on the CCD surface or camera lens. This may cause mis
measurement.

Move the cursor to 9 SAVE IN FLASH MEM or 0 OPERATIONS menu line and
press the SET key. The message below will appear on the upper part of the
screen. Press the SET key at this point. All of the image data and data settings
will be stored in the flash memory.

(8) Operation on the [BIN.AREA SET] menu screen (setting an image for binary conversion)

1. Move the cursor to 5 THRESHOLD VALUE (threshold value) and press the SET key.

2. Move the cursor to L.LM (lower limit) with the left and right keys, and adjust the lower limit
threshold value with the up and down keys.

(Adjustment of threshold value)

An example of adjustment is shown below, using a white object on a black background. When
the dotted line in the window is converted to a binary image, if the lower limit is set higher, the
black part in the binary image will become larger. If the lower limit is set lower, the white part
will become larger. Increase and decrease the lower limit value, find the value at which the
white part in the binary image starts growing and the value at which the black part starts
growing. Then set the lower limit at the value halfway between these points. This will ensure
reliable operation.
