Product Description
This camera is designed to meet high performance and quality requirements while
providing ease of use.
Atmel manages the entire process, from the sensor to the camera. The result is a
camera able to work in 12 bits, with dedicated electronics that provide excellent
signal to noise ratio.
Because of the 100% aperture pixel the sensitivity of the camera is fairly high
even in near infrared.
The programmable settings let the user work with different integration times, gains
and offsets. The external trigger allows the user to synchronize the camera on an
external event while the 3-shot color mode allows very high resolution for color
image acquisition.
Applications
The performance and reliability of this camera make it well suited for the most
demanding applications such as film and document scanning, semiconductor and
PCB inspection, DNA analysis, metrology, X-ray imaging, etc...

Improvements
The Camelia 8M has been redesigned:
To add new features:
Gain: 928 steps from -5 to 29 dB
Offset: 0 to 255 LSB
Test pattern: ramps up from 0 to 2298 pixel values on each line
Median filter: to remove 1 x 1 and columns defects
To improve the electro-optical performances, in particular by:
Reducing power consumption from 8.5W down to 5.5W, using a new front
panel and internal heat sink. This lowers the CCD temperature by 5
C thus
decreasing the magnitude of "white pixels".
Decreasing the typical temporal noise from 2.7 to 2.4 LSB
To interface with more standard and more cost effective cables
To improve reliability
Camelia M1 8M is CE and FCC compliant
What changes for the user?
New additional commands for gain, offset and test pattern
RS-232 transmission speed increased from 9600 to 19200 bauds for LVDS
cameras (9600 bauds for CameraLink cameras)
Interface connectors:
DATA & SYNC is a 3M MDR connector with better availability, the same
pinout but different mechanic
RS-232 is a D-Sub 9 female for full-duplex transmission
The power supply connector has a camera standard pinout
TTL CONTROL is a new D-Sub 9 male connector avoiding the use of a Y
cable
New rear panel (see position of connectors)

The Camelia camera is powered by a single +24V power supply. It is configurable via
the serial port of the computer (by using either CommCam software or standard RS-232
communicator as TTY or Hyperterminal) for LSD cameras. Camelia is configurable via
the serial communication of CameraLink for CameraLink cameras. It also sends digital
video.
As Camelia's CCD is a full frame sensor, the user must use either pulsed lighting or a
chopper/shutter in front of the camera in order to have only incident lighting on the CCD
during integration time. The user must design an electro-optical interface to drive the
camera, the shutter/chopper or lighting by using the SHUTTER signal delivered by the
camera. If required, the system can send an external trigger or external ITC (integration
time control signal) to the camera.
The BG38 Filter is essential to have a correct white balance on Color Cameras and for
use with standard optics (for achromaticity purpose).

The readout register is along the small side of the image area (vertical image).
Pixel Geometry
Pixels are 10 m x 10 m with an aperture ratio of 100%.
Antiblooming by
Clocking
Antiblooming can be activated or inhibited (see "Serial Communication" on page 12):
Antiblooming OFF: antiblooming inhibited. This position is recommended if
antiblooming is not required for the application.
Antiblooming ON: antiblooming activated.
When binning is disabled, the antiblooming is typically efficient up to 8 times
saturation light.
