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.

Connecting the Cables

GPO Output Specifications

When exposure output is selected, signal output is valid during image sensor exposure. When strobe control output is selected, output signal timing and pulse width can be precisely set to control external devices such as strobes connected to the camera. The sensor readout signal indicates that the imager is outputting images. If you select user output, the High/Low-fixed output is obtained according to the register set value. The polarity of the GPO output signal can be changed, using the line selector. When connecting the GPO output signal, terminate the connection with 10 kΩ impedance.
The figure shows an example in which the polarity of GPO output is positive.

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.

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 disabled
As image transmission is not completed when the exposure ends, transmission of the next image cannot be started. The trigger becomes invalid.
