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.

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.

(11) Measuring the positional deviation
Press the TRG/BRT key, and the result of measuring the positional deviation (absolute position) from the stored positioning mark image will be displayed.
*1 The final evaluation result will be displayed as "OK" in the upper left corner of the screen when
all of the items have been evaluated acceptable. If there is a single unacceptable item, "NG" will be displayed.
*2 "MATCH:+09735" means that the degree of match (percentage of pixels that match) between
pixels in the new image and the stored image is 97.35%.
[The acceptance and rejection criteria based on the degree of match]
In order to evaluate acceptability based on the degree of match, first an image of a good specimen is stored for reference. Then, an image of defective specimen is compared for degree of match. Finally an image of another good specimen is compared. These comparisons establish the degree of match to be used for setting the limits used for working comparisons. For example, the degree of match for a non-defective object is 90% or more and that for a defective object is 70% or less, then the threshold value for degree of match can be set to approx. 85%. This allows the evaluation acceptability to be made.
*3 When the final evaluation result is OK, Y0 is turned ON, and a filled box is displayed. (When
the result is NG, an empty box is displayed.) When the auxiliary relay C112 is turned ON, Y0 is turned ON according to the condition set in step (9)for final evaluation output.

[The acceptance and rejection criteria based on the degree of match]
In order to evaluate acceptability based on the degree of match, first an image of a good specimen is stored for reference. Then, an image of defective specimen is compared for degree of match. Finally an image of another good specimen is compared. These comparisons establish the degree of match to be used for setting the limits used for working comparisons. For example, the degree of match for a non-defective object is 90% or more and that for a defective object is 70% or less, then the threshold value for degree of match can be set to approx. 85%. This allows the evaluation acceptability to be made.

(Adjustment of threshold)
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.
6. After setting the lower limit, press the SET key.
7. Move the cursor to 4 SET POINT (setting point) and press the SET key.
- The point setting menu will be displayed.

3-7 Position correction (example of point measurement)
In the setting example shown in section 3-6 "Existence inspection by point measurement," points were set on the segment of number display (the object to be measured), and the each of the points was checked for the correct condition.
However, the object to be measured is not always located exactly at the preset points. To deal with this problem, use the position correction function. Then, the preset coordinates of the points are corrected according to positional deviation of the actual object, and the measurement can be carried out correctly.
(1) Set the points using item (1) to (10) in section 3-6 "Existence inspection by point measurement"
(2) Using the decimal point in a 7-segment display as a positioning mark
- Move the reference point as described in items (1) to (10), in section 3-2 "Position measurement." After the setting, move the cursor to [SET-SCRN] on the MAIN OPS MENU, and press the SET key.
- The [SYSTEM SETUP] menu will be displayed. Move the cursor to 2 OBJECT TYPE
COND (conditions of object type) and press the SET key.
- The [OBJECT TYPE COND] menu will be displayed.
(3) Operation on the [OBJECT TYPE COND] (conditions of object type) menu
1. Move the cursor to 5 POS. ADJ.CAMERA1 (position correction) with the up and down keys, and press the SET key.
2. Move the cursor to REG.0-1PNTSXY (registration: 0-1, first point: XY) with the right, left, up and down keys, and press the SET key. (Correction of X-Y coordinates).
3. Move the cursor to u UPPER MENU with the up and down keys, and press the SET key.
- The [SYSTEM SETUP] menu will be displayed. Move the cursor to 0 OPERATIONS with
the up and down keys, and press the SET key.
- The MAIN OPS MENU will be displayed.
This completes the settings for position correction using a deviation measurement. Run the program, and the preset point coordinates will be moved according to the actual position of the decimal point. Then the point inspection will be conducted.

6-1 Installation conditions
[1] Lighting equipment
Lighting for the workpieces is an important factor in image processing. The lighting conditions affect the measurement results. Select the proper lighting equipment.
- Make sure there is uniform illumination of the whole measurement field where object images will be taken.
- Use flicker-free lighting equipment, such as a high frequency fluorescent lamps or halogen lamps.
- Consult us about the right lighting equipment for your application.
[Backlighting]
Light should uniformly illuminate the field behind an object, so that the IV-S20 measure the object with it's shadow. Since the shadow picture will be converted to binary values, reliable measurements can be executed.
Example:

Backlighting using surface illuminance LED
[Reflective lighting]
A light shone on the front of an object with angle will be reflected, and the IV-S20 will pick up the reflected light. If too much light is reflected, such as from a metallic surface or similar materials, a proper image may not be obtained.

Ë When using the IV-60LD
This paragraph describes how to use Sharp IV-60LD LED lighting equipment. For details about the installation and wiring of the IV-60LD, see the instruction manual. The distance between the IV-60LD and an object (distance at which to install lighting equipment) should be approximately 150mm, and the lit area is approximately 50mm × 50mm. If the lighting distance is reduced approximately 60mm, the lighting may be uneven.

When the light is projected from above the object and if reflection off the object influences the image processing, try the following countermeasures.
1Tilt the camera center axis (within a range that does not affect the image processing) to move away
from the light reflected from the object.
2Separate the camera from the lighting equipment. Install the IV-60LD lighting equipment so that it will
shines from an angle that prevents creation of the reflection.

[2] Illuminance and shutter speed
The illuminance provided by the lighting equipment and the shutter speed must be set within the proper range.
- The following graph shows the relation between illuminance and shutter speed for the IV-S20L16 camera lens (focal length 16 mm) with an aperture setting of f = 1.6. Determine the proper amount of illuminance and the correct shutter speed, by referring to this graph. Adjust the aperture as necessary.
- To measure a moving object, or to increase the image processing speed, set the shutter speed to 1/ 1000 sec. or 1/2000 sec. or faster. However, an extremely high shutter speed will require intense lighting, thereby increasing the cost.

There is a relationships as shown on page 6-6 and 6-7, among the camera installation distance, the field of view (in the vertical/horizontal direction), the lens focal length f, the aperture setting, the focal length, and the resolution.
[Example]
When the camera installation distance is 500 mm and the field of view (in the horizontal direction) is 110 mm, the optimum lens can be selected as described in the following
procedure. The required information is taken from the table on page 6-6.

1 Selecting the lens focal length, and aperture (f - stp setting)
Follow the line for a camera installation distance of 500 mm for the view (in the horizontal direction) that is closest to 110 mm, which is 114.6 mm. A 114.6 mm field of view is shown in the column for a lens focal length, f, of 16 mm. Therefore, a lens with focal length of 16 mm is considered to be optimum.

2 Considering the focal length
The actual focal length, 16.5 mm, is longer than the lens focal length, f = 16 mm, by 0.5 mm. However, if the camera installation distance of 500 mm is within the focal range (distance from an object) of the actual lens (f = 16 mm), you can use it.
1. The focus range of the IV-S20L16 camera lens (f = 16 mm) built into the IV-S20 is from 50 mm to infinity. Therefore, the camera installation distance of 500 mm is within the focal range, and the IV-S20L16 lens can be used.
2. When another lens (with a focal range of 16 mm) is used, if its focal range exceeds 500 mm, install a commercially available C mount close-up shot ring. Use a ring that is 0.5 mm thick (16.5 - 16 = 0.5 mm).

3 Resolution
When the displayed image fills the whole monitor screen, and the view (in the horizontal direction) is 114.6 mm wide, the resolution is 223.9 µm.

Notes
- The values shown in the tables on page 6-5 and 6-6 are only reference data for installation. These values may vary, according to the characteristics of lenses you are using. When using any lens, check the data using the actual equipment.
- If you want to use a camera lens other than the IV-S20L16, buy a lens with a C type lens base. (The IV-S20L16 has a C type lens base.)
- A lens with too short focal length (f = 4.2 mm or 8 mm) will distort the edges of the field of view.

To improve the noise resistance of the constant-voltage power supply connected to the IV-S20 main housing, observe the following precautions.
- Ground the FG terminal of the constant-voltage power supply according to the class 3 grounding.
- The power line between the IV-S20 main housing and the constant-voltage power supply must be as short as possible. (Recommended distance: less than 30 cm) Do not run the power supply line near any noise generating sources, such as electric motor lines.
- Use twisted-pair wire for the power supply line.
Note
[3] Connecting a power supply
Connect a commercially available constant-voltage power supply to the power terminals (POWER: +24 V, 0 V) on the IV-S20 main housing. Use a 24 VDC ± 10%, 350 mA or more constant-voltage power supply.
- Use an individual power supply to supply power to the IV-S20 main housing. If the power supply is used to power other equipment, measurement errors may occur.
- Check the polarity of the power supply terminals, +24 V and 0 V. If power is supplied with the polarity inverted, the IV-S20 main housing may be damaged.
- Only connect or disconnect the camera cable and other equipment while the power is OFF.

Note
The constant voltage power supply (24VDC) connected to the IV-S20 main housing should not be ground its positive terminal.
- If the positive terminal of the constant voltage power supply is grounded while using external equipment connected to the SG or FG terminals, the short circuit shown below will be created. This circuit will let a large current flow through the SG line inside the IV-S20, and may destroy the circuit, or cause smoke or a fire.
- If the positive terminal of the 24 VDC power supply must be grounded for facility construction reasons, make sure to provide an independent power supply (exclusively for use with the IV-S20) which does not ground either the positive or negative terminals.
