System Precautions
Precautions
Read these precautions and this manual carefully before using the camera.
Confirm that the camera’s p ackaging is u nd am aged before opening it. If the packaging is damaged please
contact the relevant logistics personnel.
Do not open the housing of the camera. The warranty is voided if the housing is opened.
Keep the camera housing temperature in a range of 0 °C to +65 °C during operation.
Do not operate the camera in the vicinity of strong electromagnetic fields. In addition, avoid electrostatic
charging, violent vibration, and excess moisture.
To clean the device, avoid electrostatic charging by using a dry, clean absorbent cotton cloth dampened
with a small quantity of pure alcohol. Do not use methylated alcohol. To clean the surface of the camera
housing, use a soft, dry cloth. To remove severe stains use a soft cloth dampened with a small quantity of
neutral detergent and then wipe dry. Do not use volatile solvents such as benzene and thinners, as they
can damage the surface finish. Further cleaning instructions are below.
Though this camera supports hot plugging, it is recommended that you power down and disconnect
power to the camera before you add or replace system components.
Electrostatic discharge and the CMOS sensor
Image sensors and the camera bodies housing 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. The charge normally dissipates within 24 hours and the sensor returns to normal operation.
Additional information on cleaning the sensor window and protecting it against dust, oil, blemishes, and
scratches can be found here: Appendix D: The Sensor Window.

1. The Piranha4 Color Camera
Camera Highlights
Based on Teledyne DALSA's unique CMOS color line scan sensor architecture, the Piranha4 2k and 4k
Trilinear and Quadlinear color cameras provide outstanding signal-to-noise performance for high speed
imaging. The Piranha4 4k model has 4k resolution with a 10 µm x 10 µm pixel size for optimized optical
design. The 2k model has 2k resolution with a 14 µm x 14 µm pixel size. The cameras deliver a maximum
line rate of 70 kHz.
Precise sensor alignment simplifies multiple camera calibration at the system level. GenICam ™ or ASCII
command-compliant interfaces make the camera easier to setup, control, and integrate. Programmable
features include exposure control, flat field correction, and gain settings. The Piranha4 camera is ideal for
the inspection of printing, printed circuit board, solar cell, film, and large format webs.

Piranha4 cameras are GenICam compliant. They implement a superset of the GenICam ™ Stand ard
Features Naming Convention specification V1.5. This description takes the form of an XML device
descrip tion file resp ecting the syntax d efined by the GenApi m od ule of the GenICam™ sp ecification. The

Sensor Responsivity and Design
Responsivity
The responsivity graph illustrates the sensor’s response to different wavelengths of light (excluding lens
and light source characteristics).
Note: The responsivity of a color camera will measure approximately 1/ 6th that of a similar monochrome
camera model as a result of the effect the color filter has on the sensor and also due to the color camera
not incorporating TDI Mode.

Filters
CMOS cameras are responsive to infrared (IR) wavelengths of light. Infrared light can be problematic
with halogen light sources but is not an issue with white LED sources. When infrared light is present with
this camera color fidelity is reduced. To prevent infrared from distorting the images you scan, use an IR
cut off filter such as a BG-38 on the lens.

Figure 10: 2K Quadlinear Sensor Line Spacing Diagram
In the case of the 4k cameras, the three lines of pixels are separated by two lines of spacing and this line
spacing is equal to 2x the sensor pixel size. In the case of the 2k cameras, only a single line of space
separates the colored lines—with the exception of the monochrome line, which has three lines of spacing.
When the image passes the three lines of pixels, the red, blue and green components for the same image
location are captured at a different time as dictated by the line spacing. The camera automatically corrects
for the line spacing to ensure that the red, blue and green components of the image pixel are all aligned
when output. However, this is only correct when the object pixel size is square; i.e., the distance moved
by the object for one EXSYNC period is equal to the width of the object pixel. In some applications it may
not be possible to achieve a ‘squ are’ object pixel as fine ad ju stment of the lens m agnification and / or the
distance moved for each EXSYNC period is not possible. This scenario may be especially apparent when
trying to integrate the camera into an existing system.
When it is not possible to generate a square object pixel, color artefacts will occur in the scan direction
and is particularly noticeable at sharp edge transitions. The size of the edge artefact is proportional to
how far the pixel is from square. To correct for this, the camera has a feature, Line Spatial Correction (or
three letter command ssa), which allows fine adjustment of the compensation mechanism the camera uses
to correct for the line spacing.
The default setting for this feature is 3 (4k model) or 2 (2k model), which is set for square object pixels.
The setting can be adjusted from 0 to 5 to compensate for rectangular pixels—whether they are too long
or to short.
The following examples of image artefacts show black to white image transitions and the associated
corrected image after applying a specific ssa setting.

Example 1. Target speed adjusted for square pixels
Line Spatial Correction = 3 (ssa = 3). This is the default condition.
Example 2. Target running slower than example 1, same EXSYNC (trigger) frequency
Line Spatial Correction = 3 (ssa = 3) Line Spatial Correction = 4.3 (ssa = 4.3)
Example 3. Target running faster than example 1, same EXSYNC (trigger) frequency
Line Spatial Correction = 3 (ssa = 3) Line Spatial Correction = 1.73 (ssa = 1.73)

Parallax correction
When the camera it is not perpendicular to the object surface the P4 color camera will exhibit color. The
parallax distortion increases when imaging at steep angles relative to the cameras imaging plain. This is
an optical effect caused by the line spacing of the three individual colors. This spacing results in a
different magnification for each line at high angles. As shown in the figure below, there is color distortion
at the extremes ends of the image but at the centre of the image the color distortion does not show up.
4096 pixels
Figure 11: Image with Horizontal Color Alignment Issues
Using the P4 color cameras Parallax Correction feature, the optical magnification for each line is adjusted
such that colors can be lined up at the extreme ends of the image without affecting the center. Using the
feature Image Distortion Correction Mode (shm = 1) this feature can be turned on. Using the feature
Image Distortion Correction Line Selector the user can select red and green to correct the distortion. Note.
The red and green lines are adjusted to to align with the center blue line. Image Distortion Parallax
Correction Pixel Stretch (sha - Set horizontal alignment in float f<value 0-3>) is used to add the amount
of correction needed to the image. The value entered here must be between 0 and 3 (decimal values are
accepted.

The figure above is the same image corrected using the parallax correction. In this example the value of 3
was used to correct the image.
