Product Description
This camera is designed to meet high performance and quality requirements while
providing easiness of use.
ATMEL manages the whole chain, from the sensor to the camera. The result is a
camera able to work in 12-bit, with a dedicated electronic offering an excellent
signal to noise ratio.
The programmable settings let the user works at different integration time and
gain. External trigger allows to synchronise the camera on external event while
hardware white balance adjustment avoids subsequent software processing.
Applications
Performance and reliability of this camera make it well suited for the most demanding
applications as film and document scanning, semiconductor and PCB inspection,
DNA analysis, metrology, X-ray imaging, etc...

Imaging System
Description
Figure 1. Imaging System
CAMELIA camera is powered by a single +24V power supply.
CAMELIA camera is configurable via the serial port of the computer (by using either
CommCam software or standard RS232 communicator as TTY or Hyperterminal).
CAMELIA camera sends digital video.
As CAMELIA's CCD is a full frame sensor, the user must use either pulsed lightning or a
chopper/shutter in front of the camera in order to have incident lightning on the CCD
only during integration time. The user must design an electro-optical interface to drive
camera, shutter/chopper or lightning 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.

Anti-blooming by
Clocking
Anti-blooming can be activated or inhibited (see "RS232 Controls" on page 11):
Anti-blooming OFF: anti-blooming inhibited. This position is recommended if anti-
blooming is not required for the application.
Anti-blooming ON: anti-blooming activated.
When binning is disabled, the anti-blooming is efficient until 8 times the saturation
Current.

Video Signal Processing
Gain
Video signal processing gain can be adjusted by setting the ''CDS gain'' via RS232: a
commutation 1x or 4x is available at the input of the video signal processing.
The 4x position is recommended for low level applications.

Timing
2x2 and 4x4 pixel binning are possible to enable previewing modes. Preview mode is
only available in Black and white otherwise the user has to use Overlay mode (but nei-
ther correction nor software LUT are applicable on displayed images).
Frame Timing
Three timing modes are available: Continuous, external triggered and Integration Time
controlled (ITC).
The signals described in the following drawings are:
Notes: 1. Pixel is defined as valid (part of the Frame) when both LEN and FEN Signals are at
Low Level.
2. The latency (called Td after) of 1 Readout line Time defined below depends on the
binning mode. For no binning, this precision is around 104 s.
3. Minimum Time at high level of LEN Signal is 10 s (Transfer Time between two lines).
4. Minimum Time at high level of FEN Signal is 4 lines readout Time (around 416 s).
5. Shutter Delay is adjustable via Commcam or RS232 commands (1, 5, 10 or 20 ms).
