Product Description
This camera is designed to meet high performance and quality requirements while
providing ease of use.
• ATMEL manages the entire manufacturing process, from the sensor to the
camera. The result is a camera that works in 12 bits, with dedicated electronics
that provide an excellent signal to noise ratio.
• The sensitivity of the camera is fairly high even in the near infrared spectrum
thanks to the 100% aperture pixel.
• The programmable settings let the user work at different integration times and
gains. The external trigger enables synchronization of the camera on an external
event, while the 3-shot color mode allows very high resolution for color image
acquisition.
Applications
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 or X-ray imaging.

Camera
The Camelia 4M is powered by a 24V power supply and is configured through the serial
port of the computer. The camera sends digital video to the FGT frame grabber.
As the Camelia's CCD is a full frame sensor, either pulsed lighting or a chopper/shutter
must be used in front of the camera during the integration time in order to obtain incident
lighting on the CCD. The user must design an electro-optical interface to drive the camera, 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.

Camelia 4M Camera
CCD Description • Image format: 28.7 mm (V) x 28.7 mm (H)
• 2048 mm (V) x 2048 mm (H) active pixels
• Readout register along the small side of the image area (vertical image)
• Pixel geometry:
– 14 µm (V) x 14 µm (H)
– 100% aperture ratio
• Antiblooming by clocking
Timing 2 x 2 and 4 x 4 pixel binning can be used to enable previewing modes.
Data rate (pixel clock): 20 MHz
Table 1. Frame Readout Times
Mode Frame Readout Times
No binning 235 ms
2 x 2 pixel binning 125 ms
4 x 4 pixel binning 70 ms
Three timing modes are available:
• Continuous
• External triggered
• Integration time controlled (ITC)
Continuous Timing Mode The camera delivers frames continuously:
• Frame N+1 integration starts as soon as frame N readout is completed.
• The integration time is set by the RS-232 interface.

External Trigger Timing Mode The external TRIG signal allows the user to control the start of frame integration:
• The rising edge of TRIG activates the start of frame integration. This rising edge is
synchronized by the camera with a precision of 112 µs.
• The integration time is set by the RS-232 interface.
• Note that the TRIG signal period must be greater than the sum of the integration
time and the frame readout time.

Integration Time Control (ITC)
Timing Mode
The external ITC signal allows the user to fully control the frame integration:
• The falling edge of ITC activates the start of frame integration. This falling edge is
synchronized by the camera with a precision of 112 µs.
• The rising edge of ITC activates the stop of frame integration. This rising edge is
synchronized by the camera with a precision of 112 µs.
• Note that the ITC signal period must be g r eater t han t he su m of t he integration time
(defined by ITC low) and the frame readout time.

Antiblooming by
Clocking
Antiblooming can be activated or inhibited (see “RS-232 Interface” on page 8):
• Antiblooming OFF: antiblooming inhibited. Recommended if antiblooming is not
• Antiblooming ON: antiblooming activated.
