Sensitivity Mode and Pixel Readout

The camera has the option to operate in either high sensitivity or low sensitivity mode or
in tall pixel mode. When in high sensitivity mode, the camera uses both line scan sensors
and its responsivity increases accordingly. When in low sensitivity mode, the camera uses
the bottom sensor. When operating in tall pixel mode, the camera operates using both
sensors, creating a 28µm x 14µm pixel. The sensitivity mode is software controlled
through QuickCam or through the ASCII command ssm.

PRELIMINARY Spyder3 GigE User Manual

2.2 Equipment Recommendations

PC Requirements

To achieve best performance, the following minimum requirements are recommended:

• Processor: AMD Athlon XP 2000+ or Intel P4 2.0GHz

• Memory: 512MB DDR-RAM PC2700

• Motherboard: Mid-end without embedded graphic card. Avoid using onboard video

cards as they may compete with other components for shared memory.

• VGA card: Nvidia GForce 2 or better (ATI not recommended). Some ATI video cards

will use a high amount of the PCI bandwidth and compete with other components,
such as the GigE network card. This may lower the expected data rate of applications.

• GigE network adapter (either PCI card or LOM): For high performance, you must use

a Intel PRO/1000 MT adapter

• Operating system: Windows 2000 (SP4), Windows XP Professional

Network Adapter Requirements

The Spyder3 GigE camera works only with network adapters based on the Intel 82546,
82541, and 82540 network chips. The driver will also function with adapters based on the
Intel 82544 chip, but these are not recommended due to bugs in the chip that can cause
control packets to be lost if sent while data is streaming.

The PCI ID for some OEM network adapters may not be automatically recognized by the
Spyder3 GigE camera. If this occurs, contact DALSA to obtain an updated INF file.

The following four Intel network adapters are recommended and are the only adapters
that are compatible with the high performance driver:

separation of more than 100 metres, you can use an Ethernet switch. Since the Spyder3
GigE camera complies with the Internet Protocol, the camera should work with all
standard Ethernet switches. However, switches offer a range of functions and
performance grades, so care must be taken to choose the right switch for a particular
application. The following switches are expected to work with the camera:

• SMC (

www.smc.com) TigerSwitch 86xxT family

Features: Layer 2 with IGMP v2.0 managed switch that supports jumbo frames
and multicast

• 3COM (

• Dlink (

Features: Layer 2 unmanaged switch that converts multicast into a broadcast

• 3COM (

8Hwww.3com.com) 3C1770x (4900 Family):

Features: Layer 2 non-blocking switch that converts multicast into a broadcast

• Dlink (

9Hwww.dlink.com) DGS-3308FG & DGS-3308-TG

Features: Layer 3 non-blocking switch that supports multicast

• Cisco (

Features: Layer 3 switch that supports multicast

Fiber-Optic Interface Requirements

In cases where no intervening switch is desired and camera-to-PC separations of more
than 100 meters are required, a fiber-optic media converter can be used with the Spyder3
GigE camera.

The FlexPoint GX from Omnitron Systems (
to fiber and vice versa. It supports multimode (MM) fiber over distances of up to 220 m
(720 ft.) and single-mode (SM) fiber up to 65 km (40 mi.) with SC, MT-RJ, or LC connector
types.

Note: Although these products are known to work with the Spyder3 GigE camera, their

inclusion in this manual does not guarantee they will meet specific application
requirements.

Shielded Ethernet Cable Requirements

In order to achieve EMC compliance, the Spyder3 camera requires the use of shielded
CAT5e or CAT6 Ethernet cables.

2.3 Drivers: Overview

High Performance Driver Mode

In high-performance mode, the Spyder3 GigE works with the High-Performance IP
Device Driver to transfer data between cameras and PCs with very low, predictable
latency at rates of up to 1 Gb/s (100 MB/s). The video data is streamed directly into PC
memory using almost no PC CPU resources. This leaves the CPU free to process
applications.

To achieve this performance level, PCs must be equipped with a GigE network interface
(also referred to as a network adapter) based on Intel’s 82540 chip. Many motherboard
manufacturers are designing this chip directly into their board in “LAN on the
motherboard (LOM)” implementations. Alternately, an Intel 82540-based network
adapter, also known as a network interface card, can be slotted into a PC.

Note: For more information and instructions on installing the drive, refer to the Spyder3

GigE Driver Manual. To view the manual, point to Programs → DALSA QuickCam →
Documentation → Spyder3 GigE Driver Manual

Note: The DALSA NetLink IP Device Driver supports LOM implementations, but the PCI

identification number for these may be different. Contact DALSA to obtain a driver
installation file compatible with LOMs.

Standard Driver Mode

In standard mode, the Spyder3 GigE operates with any vendor’s Ethernet network
adapter. The driver shipped with the adapter transfers the data to the Windows network
stack, which handles IP communications tasks.

Standard mode is recommended for applications where flexibility is more important than
performance. The Windows network stack uses significant levels of CPU processing
power to transfer data to memory, which can result in lost packets, severely degrading
performance.

Standard mode is thus suitable for applications that require bandwidths of only 100 Mb/s
or less. If this mode is used with bandwidths of 1 Gb/s, application performance will
greatly degrade when CPU usage hits 100%. Additionally, at high rates like these,
insufficient CPU resources may be available to process or even display images.

Note: For more information and instructions on installing the drive, refer to the Spyder3

GigE Driver Manual. To view the manual, point to Programs → DALSA QuickCam →
Documentation → Spyder3 GigE Driver Manual

DALSA NetLink Universal IP Filter Driver Mode

The Universal IP Filter Driver mode is recommended for applications where flexibility is
more important than performance, but more performance is required than can be
achieved using only the Windows network stack.

Similar to the drivers used in standard mode, the Universal IP Filter Driver interoperates
with any vendor’s Ethernet network adapter. The driver shipped with the adapter is still
employed, but it communicates with the Filter Driver, instead of with the Windows
network stack.

All packets related to imaging are processed with high efficiency by the Universal IP
Filter Driver. Other packets are forwarded to the Windows stack. In this way, a single
network adapter can support both an imaging application and normal corporate LAN
functions, such as web browsing and email.

Note: For more information and instructions on installing the drive, refer to the Spyder3

GigE Driver Manual. To view the manual, point to Programs → DALSA QuickCam →
Documentation → Spyder3 GigE Driver Manual

Driver Comparison

The performance metrics in 227HTable 3 may help you determine which driver mode best suits
your application requirements. The measurements were taken using an Intel P4 2.8 GHz­based PC with hyperthreading, 512 MB of memory, and Windows XP.

Although CPU performance and data transfer rates vary with PC configuration, relative
performance is roughly equivalent, independent of the PC.

With the hyper threading CPU used in these tests, the 50% CPU usage measured for the
Native Windows stack indicates that one complete processing thread was employed to
transfer the data. This leaves only one thread available for processing applications. By
contrast, with the DALSA NetLink Universal IP Filter Driver and the DALSA NetLink
High-Performance IP Device Driver, one complete thread and most of the second thread
are available for applications processing.

Virtual Serial Port Method

1. Open QuickCam. Refer to section 244H3.1 QuickCam Interface for details on installing and
running the application.

2. Select Configure → Virtual Serial Port to enable or disable the virtual serial port.

Some camera control tools can connect only to a Windows system serial port. To avoid
asking for changes from camera manufacturers, two serial COM ports in the PC can be
linked together to share the serial channel to the IP engine. Through their linkage, data
written to one port can be read by the other port, and vice-versa.

These linked serial COM ports can be either "virtual" or physical. To set up virtual ports,
use a virtual serial port driver. Some good virtual serial port drivers are available at:
http://www.softinfinity.com/ or http://www.virtual-serial-port.com/.

Alternatively, if a PC has two free physical serial ports, they can be connected together
and used as a pair, in the same manner as a virtual serial port driver.

The Serial Port Configuration dialog box allows you to attach the serial channel in
QuickCam to one port in a serial port pair, whether a physical pair or virtual pair.
Therefore, an external application needs simply to connect to the other serial port of the
pair to communicate with the camera.

3.3 First Power Up Camera Settings

When the camera is powered up for the first time, it operates using the following factory
settings:

• High sensitivity mode

• Forward CCD shift direction

• No binning

• Exposure mode 7 (Programmable line rate & max exposure time).

• 5000 Hz line rate

• Factory calibrated analog gain and offset

• Factory calibrated FPN and PRNU coefficients using the following process:

o line rate of 5000 Hz

o analog gain calibrated to an average pixel value of 248 DN

o fpn calibration

o prnu calibration

o 12 bit output

4.2 Optical Interface

Illumination

The amount and wavelengths of light required to capture useful images depend on the
particular application. Factors include the nature, speed, and spectral characteristics of
objects being imaged, exposure times, light source characteristics, environmental and
acquisition system specifics, and more. DALSA’s Web site,
provides an introduction to this potentially complicated issue. See “Radiometry and
Photo Responsivity” and "Sensitivities in Photometric Units" in the CCD Technology
Primer found under the Application Support link.

It is often more important to consider exposure than illumination. The total amount of
energy (which is related to the total number of photons reaching the sensor) is more
important than the rate at which it arrives. For example, 5μJ/cm
exposing 5mW/cm

2

for 1ms just the same as exposing an intensity of 5W/cm2 for 1μs.

Light Sources

13Hhttp://vfm.dalsa.com/,

2

can be achieved by

Keep these guidelines in mind when setting up your light source:

• LED light sources are relatively inexpensive, provide a uniform field, and longer life
span compared to other light sources. However, they also require a camera with
excellent sensitivity, such as the Spyder3 GigE camera.

• Halogen light sources generally provide very little blue relative to infrared light (IR).

• Fiber-optic light distribution systems generally transmit very little blue relative to IR.

• Some light sources age; over their life span they produce less light. This aging may

not be uniform—a light source may produce progressively less light in some areas of
the spectrum but not others.

Filters

CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent
infrared from distorting the images you scan, use a “hot mirror” or IR cutoff filter that
transmits visible wavelengths but does not transmit wavelengths over 750nm. Examples
are the Schneider Optics™ B+W 489, which includes a mounting ring, the CORION™ LS­750, which does not include a mounting ring, and the CORION™ HR-750 series hot
mirror.

Lens Modeling

Any lens surrounded by air can be modeled for camera purposes using three primary
points: the first and second principal points and the second focal point. The primary
points for a lens should be available from the lens data sheet or from the lens
manufacturer. Primed quantities denote characteristics of the image side of the lens. That
is, h is the object height and h

is the image height.

the object distance must be 450mm (0.450m).

5.1 Electrostatic Discharge and the CCD Sensor

Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide
semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge
(ESD).

Electrostatic charge introduced to the sensor window surface can induce charge buildup
on the underside of the window that cannot be readily dissipated by the dry nitrogen gas
in the sensor package cavity. When charge buildup occurs, surface-gated photodiodes
(SGPDs) may exhibit higher image lag. Some SGPD sensors, such as the IL-P4 and the IT­P4 used in the Spyder3 GigE cameras, may also exhibit a highly non-uniform response
when affected by charge buildup, with some pixels displaying a much higher response
when the sensor is exposed to uniform illumination. The charge normally dissipates
within 24 hours and the sensor returns to normal operation.

WARNING:

!

erroneous calibration, ensure that you perform flat-field correction only after a charge buildup

Charge buildup will affect the camera’s flat-field correction calibration. To avoid an

has dissipated over 24 hours.

5.2 Protecting Against Dust, Oil and Scratches

The CCD window is part of the optical path and should be handled like other optical
components, with extreme care.

Dust can obscure pixels, producing dark patches on the sensor response. Dust is most
visible when the illumination is collimated. The dark patches shift position as the angle of
illumination changes. Dust is normally not visible when the sensor is positioned at the
exit port of an integrating sphere, where the illumination is diffuse.

Dust can normally be removed by blowing the window surface using a compressed air
blower, unless the dust particles are being held by an electrostatic charge, in which case
either an ionized air blower or wet cleaning is necessary.

Oil is usually introduced during handling. Touching the surface of the window
barehanded will leave oily residues. Using rubber fingercots and rubber gloves can
prevent oil contamination. However, the friction between the rubber and the window
may produce electrostatic charge that may damage the sensor. To avoid ESD damage and
to avoid introducing oily residues, only hold the sensor from the edges of the ceramic
package and avoid touching the sensor pins and the window.

Scratches can be caused by improper handling, cleaning or storage of the sensor. Vacuum
picking tools should not come in contact with the window surface. CCDs should not be
stored in containers where they are not properly secured and can slide against the
container.

Scratches diffract incident illumination. When exposed to uniform illumination, a sensor
with a scratched window will normally have brighter pixels adjacent to darker pixels. The
location of these pixels changes with the angle of illumination.

5.3 Cleaning the Sensor Window

1. Use compressed air to blow off loose particles. This step alone is usually sufficient to

clean the sensor window.

2. If further cleaning is required, use a lens wiper moistened with alcohol or acetone.

3. We recommend using lint-free ESD-safe cloth wipers that do not contain particles that

can scratch the window. The Anticon Gold 9”x 9” wiper made by Milliken is both ESD
safe and suitable for class 100 environments. Another ESD acceptable wiper is the
TX4025 from Texwipe.

4. An alternative to ESD-safe cloth wipers is Transplex swabs that have desirable ESD

properties. There are several varieties available from Texwipe. Do not use regular
cotton swabs, since these can introduce charge to the window surface.

5. Wipe the window carefully and slowly.

6. When cleaning long linear sensors, it may be easier to wipe along the width (i.e. as

opposed to the length) of the sensor.

6.1 Troubleshooting

The information in this chapter can help you solve problems that may occur during the
setup of your camera. Remember that the camera is part of the entire acquisition system.
You may have to troubleshoot any or all of the following:

• power supplies • cabling

• Ethernet hardware & software • host computer

• light sources • optics

• operating environment • encoder

LED

When the camera is first powered up, the LED will glow on the back of the camera. Refer
to section

276H2.4.1 for information on the LED.

Connections

The first step in troubleshooting is to verify that your camera has all the correct

6.2 Specific Solutions

No Output or Erratic Behavior

If your camera provides no output or behaves erratically, it may be picking up random
noise from long cables acting as antennae. Do not attach wires to unused pins. Verify that
the camera is not receiving spurious inputs (e.g. EXSYNC if camera is in exposure mode
that requires external signals).

Line Dropout, Bright Lines, or Incorrect Line Rate

Verify that the frequency of the internal sync is set correctly, or when the camera is set to
external sync that the EXSYNC signal supplied to the camera does not exceed the
camera’s useable Line rate under the current operating conditions.

Noisy Output

Check your power supply voltage outputs for noise. Noise present on these lines can
result in poor video quality.

Dark Patches

If dark patches appear in your output the optics path may have become contaminated.
Clean your lenses and sensor windows with extreme care.

1. Take standard ESD precautions.

2. Wear latex gloves or finger cots

3. Blow off dust using a filtered blow bottle or dry, filtered compressed air.

4. Fold a piece of optical lens cleaning tissue (approx. 3" x 5") to make a square pad that

5. is approximately one finger-width

6. Moisten the pad on one edge with 2-3 drops of clean solvent—either alcohol or

acetone. Do not saturate the entire pad with solvent.

7. Wipe across the length of the window in one direction with the moistened end first,

followed by the rest of the pad. The dry part of the pad should follow the moistened

DALSA 03-032-10158-04

PRELIMINARY Spyder3 GigE User Manual

end. The goal is to prevent solvent from evaporating from the window surface, as this
will end up leaving residue and streaking behind.

8. Repeat steps 2-4 using a clean tissue until the entire window has been cleaned.

9. Blow off any adhering fibers or particles using dry, filtered compressed air.

Horizontal Lines or Patterns in Image

A faulty or irregular encoder signal may result in horizontal lines due to exposure time
fluctuations; ensure that your exposure time is regular. If you have verified that your
exposure time is consistent and patterns of low frequency intensity variations still occur,
ensure that you are using a DC or high frequency light source.

A2.2 Analog and Digital Signal Processing Chain

Processing Chain Overview and Description

The following diagram shows a simplified block diagram of the camera’s analog and
digital processing chain. The analog processing chain begins with an analog gain
adjustment, followed by an analog offset adjustment. These adjustments are applied to
the video analog signal prior to its digitization by an A/D converter.

The digital processing chain contains the FPN correction, the PRNU correction, the
background subtract, and the digital gain and offset. All of these elements are user
programmable.

Analog Processing

Optimizing offset performance and gain in the analog domain allows you to achieve a
better signal-to-noise ratio and dynamic range than you would achieve by trying to
optimize the offset in the digital domain. As a result, perform all analog adjustments
prior to any digital adjustments.

1. Analog gain (

signal strength before the A/D conversion. It is used to take advantage of the full
dynamic range of the A/D converter. For example, in a low light situation the
brightest part of the image may be consistently coming in at only 50% of the DN. An
analog gain of 6 dB (2x) will ensure full use of the dynamic range of the A/D
converter. Of course the noise is also increased.

2. The analog offset (

introduced into the video path to ensure that the A/D is functioning properly. The
analog offset should be set so that it is at least 3 times the rms noise value at the
current gain.

Spyder3 GigE User’s Manual PRELIMINARY

65

To optimize camera performance, digital signal processing should be completed after any
analog adjustments.

1. Fixed pattern noise (FPN) calibration (calculated using the

63Hccf command) is used to

subtract away individual pixel dark current.

2. The digital offset (

64Hsdo command) enables the subtraction of the “artificial” A/D

offset (the analog offset) so that application of the PRNU coefficient doesn’t result in
artifacts at low light levels due to the offset value. You may want to set the

65Hsdo value

if you are not using FPN correction but want to perform PRNU correction.

3. Photo-Response Non-Uniformity (PRNU) coefficients (calculated using the

67Hcpa commands) are used to correct the difference in responsivity of individual pixels

66Hccp or

(i.e. given the same amount of light different pixels will charge up at different rates)
and the change in light intensity across the image either because of the light source or
due to optical aberrations (e.g. there may be more light in the center of the image).
PRNU coefficients are multipliers and are defined to be of a value greater than or
equal to 1. This ensures that all pixels will saturate together.

4. Background subtract (

68Hssb command) and system (digital) gain (69Hssg command) are

used to increase image contrast after FPN and PRNU calibration. It is useful for
systems that process 8-bit data but want to take advantage of the camera’s 12 bit
digital processing chain. For example, if you find that your image is consistently
between 128 and 255DN(8 bit), you can subtract off 128 (

Calibrating the Camera to Remove Non-Uniformity (Flat
Field Correction)

Flat Field Correction Overview

Note: The QuickCam software that ships with the Spyder3 GigE camera has a flat field correction
wizard. For easy flat field correction, use the wizard located on the Calibration tab.

This camera has the ability to calculate correction coefficients in order to remove non­uniformity in the image. This video correction operates on a pixel-by-pixel basis and
implements a two point correction for each pixel. This correction can reduce or eliminate
image distortion caused by the following factors:

• Fixed Pattern Noise (FPN)

• Photo Response Non Uniformity (PRNU)

• Lens and light source non-uniformity

Correction is implemented such that for each pixel:

V

output

Note: If your
illumination or white
reference does not

view of the camera,
the camera will send a
warning.

input

where V

V

PRNU( pixel) = PRNU correction coefficient for this pixel

FPN( pixel ) = FPN correction coefficient for this pixel

Background Subtract = background subtract value

System Gain = digital gain value

The algorithm is performed in two steps. The fixed offset (FPN) is determined first by
performing a calibration without any light. This calibration determines exactly how much
offset to subtract per pixel in order to obtain flat output when the CCD is not exposed.

The white light calibration is performed next to determine the multiplication factors
required to bring each pixel to the required value (target) for flat, white output. Video
output is set slightly above the brightest pixel (depending on offset subtracted).

Flat Field Correction Restrictions

It is important to do the FPN correction first. Results of the FPN correction are used in the
PRNU procedure. We recommend that you repeat the correction when a temperature
change greater than 10°C occurs or if you change the analog gain, integration time, or line
rate.

PRNU correction requires a clean, white reference. The quality of this reference is
important for proper calibration. White paper is often not sufficient because the grain in
the white paper will distort the correction. White plastic or white ceramic will lead to
better balancing.

03-032-10158-04 DALSA

Spyder3 GigE User’s Manual PRELIMINARY

For best results, ensure that:

• 50 or 60 Hz ambient light flicker is sufficiently low not to affect camera performance

and calibration results.

• For best results, the analog gain should be adjusted for the expected operating

conditions and the ratio of the brightest to darkest pixel in a tap should be less than 3
to 1 where:

69

Brightest Pixel (per tap)

3>

Darkest Pixel (per tap)

• The camera is capable of operating under a range of 8 to 1, but will clip values larger

than this ratio.

• The brightest pixel should be slightly below the target output.

• When 6.25% of pixels from a single row within the region of interest are clipped, flat

field correction results may be inaccurate.

• Correction results are valid only for the current analog gain and offset values. If you
change these values, it is recommended that you recalculate your coefficients.

This algorithm is recommended for use only when FPN is
negligible and FPN coefficients are set to zero. Since this

Subtracting Background

Purpose: Use the background subtract command after performing flat field

correction if you want to improve your image in a low contrast
scene. It is useful for systems that process 8 bit data but want to
take advantage of the camera’s 12 bit digital processing chain.
You should try to make your darkest pixel in the scene equal to
zero.

1 = This algorithm first adjusts each

tap’s analog gain so that 8-13% of pixels
within a tap are above the value
specified in the target value parameter.
PRNU calibration then occurs using the
peak pixel in the region of interest.

calculation is performed for all sensor
pixels but warnings are only applied to
pixels in the region of interest. This
algorithm is useful for achieving
uniform output across multiple
cameras.

3 = This algorithm includes an analog

gain adjustment prior to PRNU
calibration. Analog gain is first adjusted
so that the peak pixel value in tap’s ROI
is within 97 to 99% of the specified
target value. It then calculates the
PRNU coefficients using the target
value as shown below:
