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 accu-
rate 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.

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 measure-
ment, 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.

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.

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 inspec-
tion, 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.

- Inspection procedure
1Determine the measurement points (K0 to K3) from the mid points of the leads
and the reference line.
2Calculate the distances between the leads (D0 to D2) using the measurement
points.
3Calculate the lead lengths (L0 to L3) from the measurement points (K0 to K3)
toward the lead measurement limit line.
Purpose
Example
Based on positional information obtained from the gray scale search function,
inspect the condition of the IC leads and connector pins. (No. of lead pins that can
be detected in one image: Max. 128.)
Application Inspect the IC leads and connector pins.

(7) Multiple position measurement
The IV-C35M can detect up to 128 workpieces whose images exceed the specified
matching level (gray search) or threshold value (edge detection) compared with the
reference image.
- The positional deviation measurement needs to have a number of positions
registered for measurement. However, this measurement only requires you to
register one position and reduces the set up time.
Purpose
Example
Application Position measurement of workpieces having complicated density conditions, that
could not be measured by conventional binary conversion and density processing.
[Measurement results]
- Number of points detected
- Coordinates detected for each points
[Measured results]
- Number of images detected
- Coordinates and degree of match detected for each image
●Gray search
●Edge detection
This is useful for obtaining the distance between the coordinates of a position.
- L1 to L3 can be calculated by measuring distances and angles.
