Overview
The XCL-5000 is a monochrome digital video camera
module. This camera module outputs digital images
utilizing LVDS via the digital interface connector.
Features
Digital interface connector
Equipped with a Camera Link standard small connector.
The XCL-5000 can output a digital image at 15 frames
per second.
High image quality
The XCL-5000 has a progressive scan CCD of
5,000,000 pixels. Both cameras produce high-resolution
images. By adopting square pixels, images can be
processed using the original aspect ratio without a
converting procedure.
Various mode settings
Sending a command from the host device allows the
following mode settings.
•Gain
• Read mode: normal /binning
• Partial scan
• Shutter: Normal/Trigger shutter
• Shutter speed
• Gamma
• Edge detection, Edge emphasis
• Binarization
• Switching an Output Bit Length
Electronic shutter function
Shutter speed can be selected from variety of available
speeds.
External trigger shutter function (2 to
1/10000 sec.)
You can obtain a freeze picture by inputting an external
trigger. This function is useful to shoot a fast-moving
object clearly.
Partial scan
The camera module can limit the number of effective
video output lines to achieve high frame rates, enabling
high-speed image processing.
Binning
By “binning” two pixels that align vertically, you can
acquire a frame rate twice as high as that in the normal
mode.
Body fixing
The screw holes to install the camera module are located
under the front panel (the CCD reference plane).
Installing the camera module on the front panel
minimizes deviation of the optical axis.
Gamma
You can select Off, Manual or Default. When you select
Manual, you can draw up an original gamma line.
Edge detection, Edge emphasis
Edge detection detects an Edge from a picture, and
outputs an image made of the Edge only.
Edge emphasis outputs a clear image emphasized on the
Edge.
Binarization
Outputs an binarized image. Threshold can be changed.
Switching an Output Bit Length
You can select 12 bit output, 10 bit output, or 8 bit
output.
Note
The CCD is driven at high speed during a Partial scan or
Binning operation. In this situation, if intense light is
input to the camera, the peripheral areas of the video
image may be affected. In such a situation, adjust the
amout of light using the iris.
Overview
Typical CCD Phenomena
4
Typical CCD Phenomena
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
Step between left and right
As CCD used in this camera adopts the left-right 2ch
output system, left half and right half of the window are
output individually. Sometimes a step or line may appear
in the center of the window according to 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.

board compatible with the Camera Link feature.
In the board corresponding to PCI 32 bit, the frame
rate may become low according to lack of
processing capacity. When you want to make this
product output 15 frames per second, use a board
corresponding to more than PCI 64 bit (PCI-X).
You can use a cable of 5 meters, and you can
extend it up to 10 meter by using a repeater
(commercially available). Select a proper cable as
the maximum usable length of a cable differs due
to the attribute of each cable.
Spotted noise may appear in a specific brightness
in the window according to the attribute of the
cable. If this noise is an obstacle, shorten the
cable.

Functions
CCD loaded on XCL5000
The 500 million-pixel CCD loaded on XCL-5000 has
two signal outputs-left and right two channels output
system CCD-in order to improve the frame rate. There is
a boundary of two picking up areas in the center of the
window. The left and right signals of the boundary are
conflated into a picture by digital signal process.
Each area of the two channels output system CCD has its
output. Even so, the boundary does not appear in the
center of the window when the left and right signals are
conflated into a picture if the output characteristic
accord with each other. It is, however, very difficult for
the CCD producing technique to make two amplifier
characteristics accord completely, and the output levels
of left and right may differ. In this case, a boundary
appears in the center of the window due to the difference
of the left and right levels. XCL-5000 has an automatic
correction function that automatically detects and
corrects the difference between the levels in order to
make it indistinguishable. The automatic correction
function is set to on in the factory setting. Otherwise you
can cancel the automatic correction function and set the
correction of left and right levels manually.
A step or a boundary may be seen in the center of the
window according to the camera setting mode. This is
not a malfunction. The boundary is especially easily
seen in the Gainup.

Partial scan mode
In this mode, the desired area is read out as the effective
image portion from the effective image area that is
vertically divided into approximately 16 areas, and the
redundant image area is transmitted at high speed to
increase the frame rate. Set the block numbers for highspeed transmission (Read beginning block point PSAH)
and for normal transmission (Read block number
PSAF).
Number of effective image lines
Effective image lines: 128 × (PSAF + 1) lines
PSAF: 0 to 15
When the bottom area of the window is included in the
selected area, the effective image lines decrease for the
lines of the invalid image area. The number of lines of
the invalid image is not steady. It differs according to the
value of PSAH or PSAF.
Starting/Ending point of effective image
The PSAH value of just before the effective image
starting point determines which line of the CCD
effective pixel will be the effective image starting point.
It involves fine adjustment of the timing inside the highspeed transmission length and the lines for 1 block are
not simply 128. It differs according to the PSAH value.
Also, after you have set an effective image ending point
of an area selection, if you specify this point as a starting
point of another setting, the two points may differ. This
is due to the operation principle stated above and is not
a malfunction.

Note
In partial scan operation of this camera, the proper
image is not output for the beginning 38 lines in which
the standard black level is not steady because that CCD
is driving at high speed. For this reason, when the
normal scan mode is changed to the partial scan mode,
the effective image area is shifted up 38 lines.
Therefore in the partial scan mode, the image is
displayed 38 lines above in comparison with the normal
mode. As the result, the effective image area will be
changed and become 2016 lines. Also, when you select
the lowest area of the window in the partial scan mode,
an invalid image area (including the optical block) is
displayed in black. This is normal, not a malfunction.
When you switch the normal mode and the partial scan
mode repeatedly, if the 38-line shift described on the left
poses a problem, set to the partial scan mode instead of
the normal mode and select the whole window area in
order to use it without the image shift. In this case, the
effective image area will be 2016 lines.
