Typical CCD Phenomena
Overview
Power supply
Use a stable power source free from ripple or noise.
Locations for operation and storage
Avoid operation or storage in the following places.
• Extremely hot or cold locations. Recommended
temperature range for operation is 0 °C to 40 °C
(32 °F to 104 °F).
• Locations subject to strong vibration or shock.
• Near generators of strong electromagnetic radiation
such as TV or radio transmitters.
Care
Use a blower to remove dust from the surface of the lens
or optical filter. Clean the exterior with a soft, dry cloth.
If the camera is very grimy, apply a cloth soaked in a
mild detergent then wipe with a dry cloth. Do not apply
organic solvents such as alcohol or benzine which may
damage the finish.
Note on laser beams
Laser beams may damage a CCD. You are cautioned
that the surface of a CCD should not be exposed to
laser beam radiation in an environment where a laser
beam device is used.
The following effects on the monitor screen are
characteristic of CCD cameras.
They do not indicate any fault with the camera module.
Smear
This occurs when shooting a very bright object such as
electric lighting, the sun, or a strong reflection.
This phenomenon is caused by an electric charge
induced by infrared radiation deep in the photosensor. It
appears as a vertical smear, since the CCD imaging
element uses an interline transfer system.
Vertical aliasing
When you shoot vertical stripes or lines, they may
appear jagged.
Blemishes
A CCD image sensor consists of an array of individual
sensor elements (pixels). A malfunctioning sensor
element will cause a single pixel blemish in the picture.
(This is generally not a problem.)
White speckles
While CCD image pickup device is made by an accurate
technique, imperceptible speckless may rarely come up
on the screen due to cosmic rays and so on. This is
connected to the principle of CCD image pickup device,
not a malfunction. And the white speckless are easy to
come up in the following conditions.
• Using the camera in high temperature
• When turning up the gain
• With slow-shutter settings
Blooming
This is a phenomenon in which the light from very
bright objects appears to overflow into neighboring
areas in an image.
Level differences between left and right
as well as top and bottom
As the CCD used in the camera adopts a 4-channel
output system, the image area is divided into quarters to
be output individually. Sometimes level differences
among these four sections may occur or border lines
may be seen vertically or horizontally at the center of the
screen, depending on the setting mode of the camera.
This is not a malfunction.
Note
If strong light enters a wide area of the screen, the screen
may become dark.
This is not a malfunction. If this occurs, avoid strong
light or adjust the lens iris to reduce the light amount.

Network
Network Settings
For the camera to be connected to a network, the
following address data must be properly specified:
• IP address
• Subnet mask
• Default gateway
The camera provides the following three methods for the
address data setting:
• Using Persistent IP
• Using DHCP
• Using Link Local Address (LLA)
Using Persistent IP
Use this method when the IP address to be assigned to
the camera has been specified in advance. When using
the persistent IP, subnet mask and default gateway
settings are also required.
Using DHCP
The camera is equipped with a function to automatically
obtain an IP address by communicating with a DHCP
server on a network. When using the DHCP method for
IP address setting, the subnet mask and default gateway
values automatically obtained from the DHCP server are
also used.
Packet Delay
The delay amount to be inserted between packets can be
set when sending them to a network. By increasing the
packet delay, you can reduce the network bandwidth that
the camera uses for sending packets. However, as the
amount of data sent in a certain time is decreased with
increased delay, the frame rate of output images of the
camera may be consequently decreased.
Notes
• Any persistent IP address can be entered, but the
camera may become unable to be detected, depending
on the IP address setting. If this occurs, use a tool for
issuing ForceIP and set a persistent IP address again.
• The packet size and payload size (amount of data per
frame) settings that conform to the forbidden
condition described below are invalid. If such invalid
setting is made, an error occurs. In such a case, change
the packet size or payload size to an appropriate value.
Forbidden condition: The remainder is 4 or 8 when the
payload size is divided by (packet size – 36).
The payload size (in bytes) is calculated from the
image size (Width × Height) and pixel format as
follows:
Mono8: Width × Height
Mono10Packed/Mono12Packed: Width × Height ×
1.5
• When setting the parameters (Width, Height, and
PixelFormat) for calculating the payload size, stop
camera image output beforehand.
Using LLA
If neither Persistent IP nor DHCP is used, or if an IP
address cannot be obtained from the DHCP server, the
IP address is determined by LLA. The IP address
determined by LLA will be 169.254.XXX.YYY, with
XXX and YYY automatically specified.
In addition, the following network settings can be
changed.
• Packet size
• Packet delay
Packet Size
The amount of image data per packet can be set in bytes.
To permit the camera to operate properly, set the packet
size to a value less than the MTU of the network device
connected to the camera.

Reset Functions
This camera has the following reset functions for
returning operations to the initial conditions:
• Camera reset
• Camera setting reset
Camera Reset
Reset is executed by accessing the DeviceReset register.
The camera is restarted. This is the same operation as
that when you turn the power off then back on again.
Camera Setting Reset (Initializing)
This reset is executed by holding the reset button on the
rear panel pressed for more than three seconds. Then the
camera is restarted.
The following network settings are returned to their
default values with this reset operation:
Packet size, packet delay, use/nonuse setting of the
persistent IP address and the set values (IP address,
subnet mask, default gateway), use/nonuse setting of
DHCP
In addition, the camera settings are changed as follows:
“UserSetDefaultSelector” is set to “Default.”
Triggering
Trigger Operations
The camera can shoot images according to trigger
signals supplied from external devices. If no operation
with a trigger signal is selected, the camera performs
free-run image output according to the exposure time
and frame rate settings. In Free-Run mode, the frame
rate is automatically adjusted to the maximum value
according to the exposure time setting. The frame rate
can also be fixed when required. The sensor output
shown in the figures below is a signal (SensorReadOut)
which indicates that the imager output is valid. The
signal can be fed out from the GPIO-OUT connector.

When the camera is in Trigger Edge mode, it starts
shooting by detecting the rising or falling edge of a
trigger signal and performs shooting for the exposure
time specified in advance.
In Trigger Width mode, shooting is performed by
detecting the effective period of the trigger signal as the
exposure time.

Special Trigger Modes
In a normal trigger operation, the settings, such as
exposure time, gain and imaging region, must be
changed in advance for each trigger input when shooting
under different conditions. Such setting changes can be
eliminated by activating a special trigger mode which
makes shooting under different conditions easier. Up to
16 configurations of camera settings can be used. There
are two types of special trigger modes: Bulk mode, in
which shooting continues after being started by a trigger
signal, and Sequential mode, in which shooting is
performed each time a trigger signal is detected. The
next exposure will start after the current image output is
completed. Therefore, the second and subsequent
trigger signal inputs in Sequential mode must be more
than 3 msec. after the end of the preceding image output.
In Trigger Edge mode, the time from when detecting a
trigger signal to when starting exposure is 1.5 usec.
Shooting is performed according to the “Exposure
Time” specified in advance.
In Trigger Width mode, “Minimum Delay” operation or
“Exact Exposure Time” operation can be selected. The
relationship between the time till starting exposure and
the exposure time are shown in the table below.

Trigg er Shif t
The camera can perform exposure by the next trigger
even during image transmission (except in Special
Trigger mode). In such case, as the trigger signal can be
a noise source, use the camera with Trigger Shift
activated. When Trigger Shift is active, the time between
trigger input and start of exposure is automatically
adjusted to avoid noise generation, causing a delay of
one line at maximum in starting exposure. When Trigger
Shift is deactivated, the delay adjustment is not made
and exposure always starts with the same timing, but
noise may be mixed into images. Even if Trigger Shift is
active, triggering may be disabled, or exposure may be
defective while an image transmission is in progress and
the next transmission cannot be started. Select a
sufficient trigger interval (see “Trigger Input
Specifications” (page 8)).
Setting parameter: TriggerShift = On
Example of next image transmission
