Outline

Chapter 1: Outline

The IV-C35M compact color image sensor camera has an integrated color image processing function
to inspect and measure images, that could not be inspected or measured using a monochrome
camera. Thanks to SHARP's unique partial image capture function and a high-speed gray search
function, it will reduce overall processing time. It will not only contribute to high-speed, high-efficiency
inspection and measurement processes, but also help you keep your prices competitive.

1-1 Features

A variety of color filters and a color extraction function clearly distinguish subtle differences
in tone and density.

In addition to filtering the three primary colors (red, green, and blue), the IV-C35M can make accu­rate images of objects using brightness and other optional filters.

Color filter functions for the three primary colors (RGB) and brightness and 5 optional

filters.

Select the color components and brightness of an area you want to evaluate, and display just the
specified component brighter. Then convert it to a 256 gray scale or binary image.
The color filter can be set to display the specified color brightly after gray scale image processing.
This is effective in evaluating subtle differences in color, or for finding flaws or dirt that have
similar colors or tones.

Original color image

Conventional
monochrome
processing

If the hue or color saturation
is very similar between
adjacent areas, the images
cannot be evaluated.

Conventional gray
image processing

The density of this image
can be measured. However,
the hue and color saturation
cannot be evaluated.

Brightness filter

Displays areas that are within
the specified brightness range
(within the specified upper and
lower limits) more brightly.

Custom filter

Specify the optimum color filter
parameters to use, based on the
original image conditions. The optional
filter is effective if the RGB filters are
not used to show areas as brighter.

R (red) filter

Displays red areas more brightly.

G (green) filter

Displays green areas more brightly.

B (blue) filter

Displays blue areas more brightly.

1-2

Outline

Specify a color to extract from the original image.

The controller eliminates all areas of the image except those that have the specified color. Then, it
converts what is left into a binary image. This color extraction function not only works with hue and
saturation, but also with brightness. Therefore, achromatic objects that cannot be processed using
a color filter can still be extracted.
The controller can extract up to 8 colors in one object type. By specifying multiple object types, it
can be used to evaluate even more colors.

The measurement menu has been improved further by adding new menu items.

In addition to conventional measurement menu items, new items have been added for color related
functions including evaluating the color of objects, uneven color inspection, color positional measure­ment, and fault inspection. You can select the menu program items that match your application from 18
measurement menu items.

Easy operation menu

Setting wizard

The IV-C35M wizard asks you to make selections using a questionnaire, thus allowing anyone to set
up the measurement operations and preferences, and decrease the chance of mistaken settings.

Color extraction

For example, you can extract just the blue
area of the letter E in the image on left.

Color filer

* When a monochrome camera is connected to the IV-C35M, the color evaluation,

color unevenness inspection, and color position measurement features cannot be
used.

Shorten the cycle time by connecting two cameras

The two IV-C30C5 color cameras or two IV-S30C3/C4 high-speed monochrome cameras can be
simultaneously connected to IV-C35M controller. By connecting two cameras, your system can reduce
the processing time by positioning two areas at the same time, and then inspecting two areas at the
same time. By triggering the cameras at the same time, the system can capture two images, and
display the images above and below each other, or left and right.
Note: Combined use of a color camera and a high-speed monochrome camera is not possible.

High-speed processing now possible using a color camera or a high-speed monochrome

camera and partial image capture

Sharp's unique partial image function offers high-speed image capture.

Outline

CCD trigger function does not need an external sensor

After a trigger window is setup, the IV-C35M does not need an external sensor if it is scanning
moving objects. To set up a trigger, you can select from color, binary image conversion, average
density, gray search, and edge detection techniques. The gray search mode is useful for a
workpiece for which you cannot easily establish the density range.

Shutter speed freely set

The shutter speed can be set anywhere between 1/30 and 1/10000 second for each object type.
Practically, this means that the light level can be adjusted without changing the lighting equipment
for each object type. The random shutter function is used to close the shutter when a trigger event is
detected, so that precise still images of moving objects can be scanned.

CE approval applied for, widely accepted in international markets

The reliability of the IV-S30 means that it can be used in units destined for overseas markets.

Displays and transfers NG images while measurements are being made

While in measurement, NG images and NG history of the IV-C35M can be seen. Using the USB
communication, the controller transfers NG images to a personal computer in approximately 7 seconds.
This is convenient to investigate NG images for feedback for designing, and contributes to quality
improvement.

Automatically stores NG images on a flash memory card.

The controller is equipped with an interface for a compact flash memory card. When a compact flash
memory card is inserted in the controller housing, NG images can be stored on the card.
A flash memory card can store up to 264 NG images.
* 512x480 pixels: When a 192 MB capacity flash memory card is used.

Read the OK/NG results easily by looking at a colored display of the measurement area and

evaluation result information.

Since the IV-C35M can display the measurement area in any color and the results of the evaluation
can be display in any specified color, you can easily see for yourself if the result is OK or NG.
This function is available even when a monochrome camera is connected.

Customize to your own specification

An IV-S30LB1 image processing library and IV-S30SP parameter setting support software are both
available. Using these tools, the menu screen can be modified to suit your specialized needs to create
your own unique image processing system.

1-2 Color extraction

The color extraction function extracts a color in a certain area from the original image, and registers it
as a reference color. The controller converts areas of color that are within the upper and lower limit
ranges of hue, saturation, and brightness of the reference color to binary images, as well as colors
outside of these ranges.
Then, the controller measures these binary images with conventional measurement procedures.

Effects of extracting color

Available measurement programs that can be used with the color extraction function are area
measurement by binary conversion, object counting by binary conversion, object identification by
binary conversion, color evaluation, color unevenness inspection, and color position measurement.

1-3 Color filter

Color filter is to filter red, green, blue, brightness, or optionally, the captured image, and display the
filtered color as bright gray.
Then, the controller measures these gray images with conventional measurement

Filter types

The color filter function can be used with positional deviation measurement, degree of match inspec­tion, lead inspection, BGA/CSP inspection, area measurement by binary conversion, object counting
by binary conversion, object identification by binary conversion, point measurement, multiple position
measurement, multiple degree of match inspection, and fault inspection.

Precautions for Use

2

Chapter 2: Precautions for Use

Pay attention to the points below when handling the IV-C35M.

(1) Installation

- Each device in the IV-C35M 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) Mounting

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-C35M (power supply for the controller) 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) Connection of cameras

Note that the IV-C35M cannot be connected with EIA cameras that are available on the market.

(5) Measurement settings

Make sure to specify 4000 ms (4 seconds) or less for the measurement processing time on each
measurement item (MEASUREMENT 0 CAMERA 1, MEASUREMENT 0 CAMERA 2, and
MEASUREMENT 1 to 4). For example, if the various tasks require 7000 ms of measurement
processing time, assign 3500 ms to MEASUREMENT 1 and 3500 ms to MEASUREMENT 2 so that
each of the assigned processing times is less than 4000 ms.
If the measurement processing time exceeds 4000 ms, the IV-C35M assumes that an abnormal
operation has occurred and may try to reset the system.

(6) Data saving

- The data set by using the remote keypad is temporarily stored in the memory (RAM) of the IV­C35M. 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 any condition settings menu by pressing
the SET key. If you do not save the data, the data will disappear when you turn OFF the power
to the IV-C35M controller.

- We recommend that you save the data settings and reference images on a floppy diskette using
the IV-S30SP parameter setting support software for the IV-C35M.

(7) Storing the devices

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

(8) Maintenance

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